Copyright © 2013 American Society of Anesthesiologists MCC Session Number – MCC01 Saturday, October 12 8:00 AM - 9:30 AM CA MC01 Difficult Ventilation and Diagnosis of Tracheoesophageal Fistula (TEF) in a Patient Post Esophagectomy Rany Abdallah, M.D., Ph.D., Jaber El-Bashir, M.D., Ayman Ads, Rush University Medical Center, Chicago, IL A 66-year-old old male with esophageal adenocarcinoma underwent esophagogastrectomy but developed shortness of breath (SOB) on POD3. On POD7 imaging showed a contrast leak suggesting anastomotic dehiscence. He was intubated for SOB and planned dehiscence repair. During transport bubbling was heard from his mouth despite cuff reinflation. In the OR 20cm H2O of PEEP was required for adequate ventilation. Surgical exploration revealed an esophageal anastomotic defect overlying a defect in the left main bronchus and confirmed a TEF diagnosis. The ETT was pushed into the right main bronchus surgical repair completed then repositioned in the trachea; providing adequate ventilation. Saturday, October 12 8:00 AM - 9:30 AM CA MC02 Acquired Hemophilia A After Coronary Artery Bypass Graft Surgery Ahmad Abou Leila, M.D., Abayomi Akintorin, Bozana Alexander, M.D., John H. Stroger Jr. Hospital of Cook County, Chicago, IL We are reporting a challenging case of a rare cause of post operative bleeding. Acquired hemophilia A is rare cause of coaguloathy that we believe was the main culprit . Patient post CABG developed nonsurgical bleeding with new isolated PTT prolongation. Bleeding was resistant to conventional therapy. Mixing studies didn't correct PTT thus we ruled out factors deficiencies. Heparin effect excluded by normal factor X levels. Patient received factor VIII inhibitor bypass therapy after which PTT corrected and bleeding stopped. The triad of acquired coagulopathy noncorrectable PTT and exclusion of heparin effect make acquired hemophilia A the most likely diagnosis. Saturday, October 12 8:00 AM - 9:30 AM CA MC03 Anesthetic Management of a 53-Year-Old Female With Metastatic Leiomyosarcoma to the Left Atrium and Right Lower Lobe Oludayo Adeyefa, M.D., University of Texas Health Science Center at Houston, Houston, TX, Ron Purugganan, M.D., Dilip Thakar, M.D., The University of Texas MD Anderson Cancer Center, Houston, TX Leiomyosarcoma is a relatively rare form of cancer and accounts for between 5-10% of soft tissue sarcomas which are in themselves relatively rare. We present the case of a 53 -year-old female with a history of uterine leiomyosarcoma s/p hysterectomy who presented with metastatic leiom year-old sarcoma to the left atrium and right lower lobe with invasion to the left pulmonary veins. Anesthetic management included one-lung ventilation for a left thoracotomy cardio pulmonary by pass and intraoperative TEE to evaluate the left atrial mass pre and post surgery. Given the carefully planned perioperative care she had a smooth intraoperative and postoperative course.

He had acute severe AI and pulmonary hypertension. Intra-op the vegetation was not present and we proceeded with AVR. While attempting to separate from CPB the cerebral saturation was 50% below baseline PaO2 on FiO2 of 1.0 was 47mmHg the SpO2 in the high 80s and SBP of 6070mmHg. He was maintained on norepinephrine 40mcg/min epinephrine 0.06mcg/kg/min milrinone 0.375mcg/kg/min vasopressin 0.12Units/min phenylephrine 2mcg/kg/min. Methylene blue 2mg/kg was added for suspected vasoplegia. This improved the BP to 110mmHg and allowed for separation from CPB. Saturday, October 12 8:00 AM - 9:30 AM CA MC05 Type IV Endoleak Detected by Transesophageal Echocardiography During Endovascular Repair of Aorta Shalin Shah, D.O., Gautam Agarwal, M.D., Manuel Castresana, Shvetank Agarwal, Georgia Regents University, Augusta, GA A 76-year-old female with traumatic transection of the descending thoracic aorta underwent endovascular aortic repair (EVAR) with TEE to guide graft placement. A single C-TAG® (W. L. Gore & Associates Inc. Flagstaff Arizona USA) endograft measuring 26mm X 21mm X 10 cm was deployed under fluoroscopic and transesophageal echocardiographic (TEE) guidance. Post-stent deployment angiographically there was no evidence of endoleak. On TEE multiple small high-velocity jets were seen traversing the entire anterior surface of the stent graft representing early type IV endoleak. We describe different types of endoleaks their diagnosis implications and management. Saturday, October 12 8:00 AM - 9:30 AM CA MC06 Anesthetic Management of Bilateral Thoracoscopic Maze for Recurrent Atrial Fibrillation: Case-Series Mark Banks, M.D., Mary Arthur, M.D., Vijay Patel, M.D., Shvetank Agarwal, M.D., Georgia Regents University, Augusta, GA Four patients with recurrent atrial fibrillation who had previously failed transcatheter ablation presented for a thoracoscopic bilateral maze procedure and left atrial appendage clipping with immediate cardiopulmonary bypass availability. Sequential lung ventilation in modified supine position created ventilatory challenges in these patients with multiple comorbidities including obesity congestive heart failure and pulmonary hypertension. Intraoperative transesophageal echocardiography was used to rule out left atrial thrombus measure left atrial and pulmonary vein size and to guide the clipping of the appendage. In this case-series we discuss the anesthetic management of sequential lung isolation in supine position and use of intraoperative transesophageal echocardiography.

Anesthetic management included general endotracheal tube anesthesia cardiopulmonary bypass availability and transesophageal echocardiography (TEE) to guide deployment of the stent-graft. Challenges included difficult vascular access shorter than usual proximal landing zone and hemodynamic instability due to rupture of the internal iliac artery during sheath removal. We discuss the various indications pre- and intra-op imaging modalities anesthetic considerations and complications of EVAR in traumatic transections of the descending thoracic aorta. Saturday, October 12 8:00 AM - 9:30 AM CA MC08 Superior Vena Cava Tear in a 70-Year-Old Female Following Lead Extraction Chad Agnew, M.D., Amy Duhachek-Stapelman, UNMC, Omaha, NE Cardiac lead extractions are associated with a number of adverse events that require rapid diagnosis and treatment. We present a case of a 70-year-old female who underwent lead extraction secondary to high impedance. Transesophageal echocardiography (TEE) probe was placed for intra-operative monitoring. During laser extraction a sudden drop in systolic blood pressure from 130s to 80s occurred. TEE revealed new significant right pericardial fluid collection. Resuscitation measures were initiated along with emergent sternotomy and cardiopulmonary bypass by cardiothoracic surgeon. A superior vena cava tear was identified and repaired. The patient was transported to ICU in stable condition. Saturday, October 12 8:00 AM - 9:30 AM CA MC09 On Pump Coronary Artery Bypass Grafting and Left Ventricular Pseudo-Aneurysm Repair in a 29-yearold Patient With Systemic Lupus Erythematosus and Antiphospholipid Syndrome and Intraoperative Heparin Resistance Nawraz Alan, M.D., Douglas Sharp, M.D., Seol Yang, M.D., Darin Zimmerman, M.D., George Washington University, Washington, DC We describe the intraopertaive care of a 29-year-old male with anti-phospholipid syndrome who required a LV pseudo-aneurysm repair and thrombus evacuation as well as CABG. He had a history of multiple arterial thromboses resulting in left BKA as well as acute lacunar infarct. Work up of his stroke revealed a LV pseudo-aneurysm with thrombus and 100% proximal LAD stenosis. In fear of a thrombotic event on CPB we elected ACT of 800s before proceeding; however this was challenging as the patient displayed heparin resistance. We will review the pathophysiology and present results of a literature search regarding intraoperative care. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM CA MC10 PEA Arrest From an Argon and/or Carbon Dioxide Gas Embolism During Laparoscopic Renal Cell Carcinoma Cryoablation Laura Alexander, M.D., Jodi Sherman, M.D., Trevor Banack, M.D., Jean Charchaflieh, M.D., Yale, New Haven, CT A 70-year-old female with RCC underwent GAET for a laparoscopic renal mass cryoablation. Three hours after abdominal insufflation in trendelenberg/right lateral decubitus positioning intra-abdominal pressure was raised to 20mmHg during argon beam cauterization. ETCO2 immediately declined from 38 to 6 with declines in O2 HR BP and a new 2mm ST depression. Medications administered; ephedrine phenylephrine epinephrine and atropine. PEA arrest developed ACLS initiated with stabilization after 6 minutes. TEE revealed; 20% LVEF severe hypokinesis and negative PFO/embolus. The working diagnosis was a CO2 and/or argon PE with resultant stress induced cardiomyopathy. Patient was extubated 2 days later and discharged home. Saturday, October 12 8:00 AM - 9:30 AM CA MC11 Anesthetic Management of a Large Obstructive Cardiac Hemangioma of the Right Ventricle Michael Allen, D.O., Sanjay Dwarakanath, M.D., Shvetank Agarwal, M.D., Georgia Regents University, Augusta, GA A 40-year-old male underwent a left anterior thoracotomy for tissue biopsy of a hypervascular right ventricular mass of unknown origin incidentally detected on the chest CT. Arterial and central venous lines were placed pre-induction in anticipation of hemodynamic instability due to right ventricular outflow tract obstruction. General anesthesia and lung-isolation was achieved with a single lumen endotracheal tube and bronchial blocker with preparations for emergent cardiopulmonary bypass. Intraoperative transesophageal echocardiography revealed a 7x6 cm mass invading the right ventricular free wall confirming preoperative transthoracic echocardiography without any evidence of tamponade physiology. The final histopathological diagnosis being a hemangioma. Saturday, October 12 8:00 AM - 9:30 AM FA MC12 Methemoglobinemia With the Use of Benzocaine Spray for Awake Fiberoptic Intubation Samer Abdel-Aziz, M.D., Mohamed Ismaeil, M.D., University of Arkansas for Medical Sciences, Little Rock, AR We report a case in which the use of benzocaine spray to facilitate awake fiber optic intubation in a patient with a difficult airway caused methemoglobinemia intraoperatively. Local benzocaine was sprayed in the patient's mouth for a total time of 1 second 15 minutes later SpO2 decreased to 85% on the pulse oximeter. Arterial blood gas showed a MetHb of 24.6% of total Hemoglobin. The patient was successfully treated with methylene blue intravenously and recovered uneventfully. Small amounts of local benzocaine sprayed to numb the airway can cause significant methemoglobinemia that requires immediate recognition and appropriate management.

The affected patient requires careful preoperative preparation and intraoperative attention. A 57-year-old female with an adrenal pheochromyctoma was scheduled for laparoscopic right adrenalectomy. Preoperatively the patient received adequate alpha-blockade. Planned laparoscopic approach was met with difficulty due to dense adhesions and converted to an open approach. During dissection the right renal vein was injured and considerable blood loss and hemodynamic instability ensued. We suspected that venous air embolism contributed to the instability. With diagnosis and treatment in an expeditious manner the patient had a favorable anesthetic outcome. Saturday, October 12 8:00 AM - 9:30 AM FA MC14 Management of a Symptomatic Long Segment Tracheal Stenosis From a Large Goiter With Intrathoracic Extension Shivon Abdullah, M.D., Benjamin Stam, B.S., Pramod Chetty, M.D., Oklahoma University Health Sciences Center, Oklahoma City, OK Symptomatic multi-level tracheal compression from neck and mediastinal masses pose a challenge for the anesthesiologist. We describe a challenging case of a 42-year-old female with a large goiter complicated by intrathoracic extension resulting in deviation and significant compression of the trachea. Without the luxury of resorting to a surgical airway in the event of airway collapse femoral arterial and venous cannulae were placed for possible extracorporeal oxygenation. The airway was secured by awake fiber-optic intubation using a reinforced tube placed distal to the level of stenosis. Due to significant tracheomalacia the patient was left intubated overnight and extubated uneventfully. Saturday, October 12 8:00 AM - 9:30 AM FA MC15 Airway Management of a Patient With Recurrent Angioedema Shady Adib, M.D., Julie Marshall, M.D., Alice Landrum, M.D., University of Missouri, Columbia, MO A 47-year-old female presented to the ER with significant tongue edema and the presumed diagnosis of lisinopril-induced angioedema. She was taken to the OR for an awake nasal fiberoptic intubation with ENT present for a possible emergency tracheostomy. The patient was extubated on hospital day two. Seven days after the initial presentation she returned with stridor but no upper airway edema and was intubated without difficulty. Our patient developed lower airway edema following resolution of tongue edema. This emphasizes the need for continued suspicion of airway edema following resolution of external swelling. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM FA MC16 Anesthetic Management of a Patient With End Stage Amyotropic Lateral Sclerosis and Severe COPD Adam Adler, M.D., M.S., Neil Connelly, M.D., Baystate Medical Center, Springfield, MA A 72-year-old female with progressive ALS presented for IR guided percutaneous-gastrostomy. With coexisting severe COPD and CHF she requested general anesthesia and the issue of neuromuscular relaxation was encountered. Induction was accomplished using propofol. ETT placement without muscle relaxation proved impossible due to small mouth opening and rocuronium 20mg was administered. Train of four was checked the presence of 4 twitches and sustained tetany observed at the orbicularis oculi muscle prior to reversal with Neostigmine+glycopyrrolate. ETT and oral suction was performed prior to extubation with equipment available for possible re-intubation. She was transferred to PACU uneventfully and discharged the following day. Saturday, October 12 8:00 AM - 9:30 AM FA MC17 Airway Management of Angioedema in the Setting of Emesis and a Grand Mal Seizure and Airway Compromise Adam Adler, M.D., M.S., Emad Attallah-Wasif, M.D., Baystate Medical Center, Springfield, CT A 47-year-old-man arrived to our emergency department with severe tongue angioedema after taking lisinopril. Initially he had garbled speech and mild respiratory distress. His symptoms were progressively worsening. Decision was made to secure his airway with an awake nasal fiberoptic intubation. Trauma surgeon was at bedside for backup surgical airway. While receiving nebulized lidocaine he became dyspnic and vomited followed by a grand mal seizure which was terminated with IV midazolam. He had pulseless electrical activity arrest and CPR was initiated for 1 min. Single pass with nasal FFB was unsuccessfully. Emergency cricothyrotomy was performed and the airway secured. Saturday, October 12 8:00 AM - 9:30 AM FA MC18 Mechanical Extraction of a Cannula Aspirated Through a Chronic Post-Laryngectomy Tracheoesophageal Fistula Adam Adler, M.D., M.S., Srinvasa Gutta, M.D., Baystate Medical Center, Springfield, MA A 71-year-old-male arrived to the ED reporting to have lost the plastic cannula used to plug a chronic tracheoesophageal fistula. The patient underwent laryngectomy 10 years prior complicated by tracheoesophageal fistula that failed surgical closure on multiple occasions. The patient denied respiratory symptoms dysphagia or odynophagia. Chest x-ray failed to localize the radiopaque object. GETA followed by bronchoscopy of the larger airway segments failed to identify the cannula. A rigid endoscope revealed the cannula in the stomach which was snared and brought to the mouth for extraction. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM FA MC19 Perioperative Myocardial Infarction as a Cause of Extubation Failure Avneep Aggarwal, Muhammad Jaffar, M.D., University of Arkansas for Medical Sciences, Little Rock, AR We report a case of extubation failure following non cardiac surgery complicated by perioperative myocardial infarction. A 68-year male was scheduled for radical cystectomy with ileal conduit for bladder cancer. The patient's past anesthetic experience was uneventful. Patient had good functional capacity and denied any cardiac symptoms. His PMH was significant for CAD COPD and obesity. Intraoperative course was significant for transient ST depression. Extubation failed despite adequate neuromuscular blockade reversal and stable hemodynamics. Post operatively elevated cardiac biomarkers were suggestive of perioperative myocardial infarction. Coronary angiography revealed triple vessel disease with 60-80% stenosis. Saturday, October 12 8:00 AM - 9:30 AM FA MC20 Positioning Pitfalls: Prone to Pulmonary Embolism Latrice Akuamoah, M.D., M.P.H., Jeffrey Silverstein, M.D., M.S., Melissa Lee, M.D., Mount Sinai Medical Center, New-York, NY A 63-year-old man with remote history of atrial fibrillation presented for C2-T1 laminectomy and fusion to treat symptomatic cervical cord compression. General anesthesia was induced followed by endotracheal intubation. The patient was turned prone. Within minutes his heart rhythm converted to atrial fibrillation he became hypotensive minimally responsive to vasopressors and end tidal CO2 decreased. He was turned supine and maintained on vasopressors which improved his hemodynamics. Arterial blood gas demonstrated increased PaCO2 and decreased PaO2. The case was canceled and he was transported to the intensive care unit for further management. Postoperative CT scan confirmed bilateral pulmonary embolism. Saturday, October 12 8:00 AM - 9:30 AM FA MC21 Total Intravenous Anesthesia for the Resection of a Large Catecholamine Secreting Tumor William Fernando Amaya-Zuniga, M.D., Monica Mora-Ortiz, M.D., Darwin Cohen-Manrique, M.D., Jorge Alvarado-Sanchez, M.D., Fundacion Santa Fe de Bogota, Bogota, Colombia A 63-year-old female presented with Pheochromocytoma (suprarrenal mass 10X8X6cm). 24-hour urine metanephrines and vanillylmandelic acid were positive. The preoperative preparation included administration of terazosin and metoprolol two weeks before the surgery achieving adequate control of blood pressure and symptoms. Given the size and the complexity of the mass an open surgical resection was considered. Total Intravenous Anesthesia (target controlled infusion of propofol and remifentanyl) and infusion of dexmedetomidine were administrated. Anesthesia was guided by Entropy monitoring; proper intraoperative hemodynamic control was achieved requiring minimum hypotensive and vasopressive drugs. This technique allowed hemodynamic stability with attenuated sympathetic response. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM FA MC22 Impending Airway Obstruction Melody Anderson, M.D., Francesco Resta-Flarer, M.D., Jonathan Lesser, M.D., Jinu Kim, M.D., St. Luke's Roosevelt Hospital, New-York, NY A 59-year-old male with fever and increased difficulty breathing over the previous two days presented to ER with inflamed airway associated with pharyngeal mass and impending airway obstruction. The patient was brought to OR for emergent airway management. First and second intubation attempts with GlideScope did not reveal identifiable anatomy. Third and fourth attempts with fiberoptic were unsuccessful secondary to pharyngeal mass obstruction and inability to enter the airway. The decision was made to proceed with tracheostomy. Return to OR the following day for tonsillectomy and pharyngeal neck exploration revealed near complete obstruction of the airway by left paratonsillar mass. Saturday, October 12 8:00 AM - 9:30 AM FA MC23 Acute Decrease of End-tidal CO2 During Pheochromocytoma Resection Elena Ashikhmina, M.D., Ph.D., Zhiling Xiong, M.D., Ph.D., Brigham & Womens Hospital, Boston, MA Mr. XXX is a 65-year-old male undergoing laparoscopic right adrenalectomy for pheochromocyroma developed an acute drop of end-tidal CO2 from 32 to 14 mmHg after insufflation of the abdomen. The opening pressure was 15 mmHg. About 4 L of CO2 was infused into peritoneal cavity. The patient remained hemodynamically stable. A transesophageal echocardiography was performed and noted no evidence of right heart strain but significant collapse of an inferior vena cava. It was concluded that the patient could not tolerate intraperitoneal pressure of 15 mmHg and the case proceeded with intraperitoneal pressure of 10 mmHg without complications. Saturday, October 12 8:00 AM - 9:30 AM FA MC24 Anesthetic Management for a Patient With Mitochondrial Metabolic Disorder Ahmed Attaallah, M.D., Ph.D., Eric Lindstrom, C.R.N.A., West Virginia University, Morgantown, WV Mitochondria is the main intracellular site for ATP production. Patients with mitochondrial metabolic disorders often have multiple organ systems deterioration predisposing them to perioperative complications. These patients vulnerable to hypoglycemia and lactic acidosis sensitive to anesthetics prone to malignant hyperthermia and have respiratory and cardiac compromises. We present a patient who suffers from refractory seizures muscle weakness decreased respiratory and cardiac reserve and impaired glucose regulation. There are conflicting reports in the anesthesia literature but most perioperative complications have been predictable and preventable. We will outline the up-to-date recommendations for perioperative management and discuss the implications on the anesthetic plan. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM FA MC25 TEE Usage for Non-Cardiac Surgery Abisola Ayodeji, M.D., Lynn Belliveau, M.D., Kalpana Tyagaraj, M.D., Maimonides Medical Center, Brooklyn, NY A 79-year-old woman with past medical history of pulmonary emboli s/p Greenfield filter was brought to the OR for repair of a colovesicular fistula and urethral obstruction. Induction and intubation were uneventful. During the procedure two acute episodes of hypoxia and hypotension occurred. Blood pressure responded to vasopressors. The hypoxia initially nonresponsive to PPV albuterol and ETT suctioning resolved spontaneously. A central line and an arterial line were placed. The diagnosis of exclusion was pulmonary microemboli. TEE showed normal cardiac function and no evidence for emboli. Case is being presented for discussion of TEE use for non-cardiac surgery. Saturday, October 12 8:00 AM - 9:30 AM FA MC26 Malignant Hyperthermia: To Be or Not to Be? Does This Patient Deserve a Label? Neda Sadeghi, M.D., Mari Baldwin, M.D., St. Lukes Roosevelt, New York, NY We present the case of a 69-year-old female undergoing plastic surgery for treatment of basal cell carcinoma . She had uncomplicated prior anesthetics. One hour into general anesthesia she became febrile to 39 degrees F hypercarbic to 80mmHg tachycardic and hypertensive. Volatile anesthesia was turned off; intravenous anesthesia commenced. Slowly her temperature normalized with active cooling measures and she improved with both tachycardia and hypercarbia abating. Post-operatively her potassium was 4.5 CK 1287. Dantrolene was not given. She was scheduled for another anesthetic in 4 weeks. How to proceed and what to tell her? Saturday, October 12 8:00 AM - 9:30 AM FA MC27 Tracheal Stent Placement in a 60-year-old Patient With Esophageal Cancer and New TrachealEsophageal Fistula Philip Bamberger, Maria Cashin, C.R.N.A., Faiz Bhora, M.D., St. Lukes-Roosevelt Hospital Center, New York, NY Tracheal stent placement in acute adult tracheal-esophageal fistula. TIVA was selected for 2 reasons: the airway would have to be shared with the surgeon and the powerful narcotic remifentanyl could be used to blunt reflex hypertension and tachycardia from tracheal stimulation. Induction was with Sevoflurane Midazolam 2 mg IV Fentanyl 100 mcg. Anesthesia was maintained with Propofol 150 mcg/kg/min and Remifentanyl 0.2 mcg/kg/min which was started at the time of induction. Rocuronium 30 mg IV. Ventilation was via intermittent jet ventilation with FiO2 =1.0. The surgeons suspended the trachea and larnyx and direct visualization placed a tracheal stent. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM FA MC28 Acute Depression After Postoperative Ondansetron Harish Bangalore Siddaiah, Ashok Rao, M.D., Shilpadevi Patil, M.D., LSUHSC, Shreveport, LA 39-year-old patient with h/o depression was for a scheduled ureteric stone removal. After completion of surgery patient was transferred to PACU where patient complained of nausea was administered 2 mg of intra-venous ondansetron. Immediately after administration patient became unresponsive to verbal and painful stimuli. Neurology was consulted immediately who assessed the patient by then patient started responding to painful stimuli and gradually to verbal stimuli but had tearing from both eyes. Focal neurological exam was within normal limits. Psychiatry team was consulted who interviewed her and diagnosed her with acute depressive episode started her on anti-depressants. Saturday, October 12 8:00 AM - 9:30 AM FA MC29 Intraoperative Management of a Patient With Pheochromocytoma and Gastrinoma Harish Bangalore Siddaiah, Ashok Rao, M.D., Shilpadevi Patil, M.D., LSUHSC, Shreveport, LA 49-year-old with a h/o severe hypertension NSTEMI was admitted with hematemesis was diagnosed with peptic ulcer disease due to gastrinoma on routine CT scan of abdomen a large pheochromocytoma was diagnosed. Patient was then started on prazosin for 10 days on day of surgery patient's preoperative blood pressure was 155/80. Patient was taken to OR and induced with propofol sufentanil rocuronium and maintained on isoflurane. As surgery progressed patient's blood pressure increased reaching 250/120 esmolol and nitroprusside drip were started immediately and were titrated to reach maximum doses though patient's blood pressure remained elevated till excision of the tumour. Saturday, October 12 8:00 AM - 9:30 AM FA MC30 Robotic Prostatectomy Impairs Cardiac Contractility Matthew Barker, M.D., Virginia Commonwealth University, Richmond, VA, John Watkins-Pitchford, McGuire VAMC, Richmond, VA An 80-year-old male 70 inches 187 pounds underwent robotic prostatectomy for benign prostatic hypertrophy. The circulation was monitored with bio-reactance (Cheetah Medical Inc). Stroke Volume Index Heart Rate and Total Peripheral Resistance were measured. A preoperative passive leg raise test(PLR) showed normal Starling fluid-responsiveness the stroke volume increasing 30.5%. Uneventful surgery proceeded with 50ml blood loss and 300ml lactated Ringer's infused. After emergence extubation and transport to PACU the PLR test was repeated with only 8% increase in stroke volume. The progreessive intraoperative fall in stroke volume after an initial rise was not accompanied by clinical pulmonary edema. Saturday, October 12 8:00 AM - 9:30 AM OB MC31 Penetrating Injury to the Gravid Uterus: Anesthetic Considerations Sarah AbdelFattah, M.D., Nicholas Nedeff, M.D., Jackson Memorial Hospital, Miami, FL Patient is a 27-year-old female G3P2002 at 34 weeks gestation who arrived to trauma center s/p gunshot wound to head and abdomen/ gravid uterus. Case describes management of the parturient in Copyright © 2013 American Society of Anesthesiologists the trauma setting including primary survey and airway management as well as physiologic changes (hemodynamically hematologically etc) in pregnancy and the considerations that must be accounted for in order to care for the patient in a penetrating trauma. Also there is discussion of when/ if to deliver the fetus and when it is appropriate to maintain the pregnant state. Saturday, October 12 8:00 AM - 9:30 AM OB MC32 Anesthetic Considerations in a Parturient With Repaired Tetralogy of Fallot and Oral-Facial Digital Syndrome Abdullah Abdullah, M.D., Jaya Ramanathan, M.D., Jenna McKinnie, M.S., University of TennesseeMemphis, Memphis, TN A 25-year-old G2P1 at 36 weeks with a history of repaired Tetralogy of Fallot and oral-facial-digital syndrome was admitted for labor. Additional cardiac surgeries included mitral valve replacement and recently pulmonary artery conduit replacement. Her medications were digoxin and lasix. Physical examination revealed stable hemodynamics and class2 airway. ECHO showed EF 50-55%. A vaginal delivery was planned. Epidural was performed with a loading dose 10 ml of 0.125% bupivacaine followed by 0.125% bupivacaine with fentanyl 5ug/ml infusion at 12ml/hour with excellent analgesia. A forceps-assisted delivery was achieved successfully with estimated blood loss 250 ml. Post-partum course was uneventful. Saturday, October 12 8:00 AM - 9:30 AM OB MC33 Cesarean Delivery and Splenectomy for Severe Idiopathic Thrombocytopenic Purpura: A Case Report Kulsum Akbar, M.D., Alexander Butwick, M.B. B.S., Stanford Medical Center, Stanford, CA The medically challenging case involves a 29-year-old G1P0 parturient who presented with lower extremity petechiae and recently diagnosed Idiopathic Thrombocytopenic Purpura (platelet count = 5x109/L). Her ITP proved refractory to various treatments including plasmapharesis. A thromboelastogram performed at 37 weeks showed low maximum amplitude (MA) and clot stability (G) causing inability to measure clot formation time (K) at which time she underwent a cesarean section and a concomitant splenectomy. Intrapartum removal of the spleen and the subsequent administration of recombinant FVIIIa proved successful in increasing her platelet count and can be considered for obstetric patients with severe refractory ITP.

After receiving an epidural the OB service artificially ruptured her membranes. Within 5 minutes she complained of severe abdominal pain chest pain and dyspnea marked by tachycardia hypotension hypoxia fetal bradycardia and altered mental status. General anesthesia was delivered and an emergent c-section was done. Her EKG rhythm transitioned from right heart strain to PEA arrest at which point ACLS was initiated. Return of circulation was obtained however she developed DIC and required a massive transfusion with over 25 units of PRBCs and FFP and Platelets. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM OB MC38 To Stick or Not to Stick: Alternative Approaches to Labor Analgesia in a Parturient With Suspected Von Willebrand Disease Eric Ashford, M.D., Johannes Dorfling, M.D., Regina Fragneto, M.D., University of Kentucky, Lexington, KY Von Willebrand disease and other inherited coagulopathies presenting in parturients during labor complicate the utilization of neuraxial anesthesia for pain management. Analgesia in parturients can be achieved through various alternative means though providers might not fully integrate the efficacy and ramifications of different medications and administration techniques. We illustrate the management of a 26-year-old parturient presenting at night with no previous prenatal care detailing an incomplete history of an inherited coagulopathy determined to be von Willebrand disease. We also discuss a literature review of the available pain management modalities and medication administration in parturients with inherited coagulopathies.

The patient refused neurosurgical intervention and so we provided percutaneous therapy. We changed the spinal cord stimulator to a constant current device and added two percutaneous quadripolar leads. The patient appreciated complete resolution of painful symptoms and was able to engage in athletic activities. This is the first report of complete resolution of post amputation pain with a change from a constant voltage to a constant current SCS. Saturday, October 12 8:00 AM - 9:30 AM PN MC48 Ketamine Infusion Therapy for Severe Aura Associated With Migraine Jared Chase, D.O., Sumit Katyal, M.D., Cleveland Clinic, Cleveland, OH A 60-year-old-female presents with persistent aura and episodic migraines for over a year. She experiences photophobia motion sensitivity visual field cuts left temporal pain and a persistent shimmering visual disturbance which interfere with her work as a radiologist. Brain MRI/MRA/MRV were normal. Her headache and persistent aura had been poorly controlled with amitriptyline meclizine NSAIDs memantine and prednisone. She failed treatment with depacon and magnesium infusions. Therapy with intravenous subanesthetic doses of ketamine for 5 days was beneficial in disrupting the cycle of persistent aura. Saturday, October 12 8:00 AM - 9:30 AM PN MC49 A Unique Case: Treatment of Supraorbital Neuralgia Using Pulsed Radiofrequency Ablation Cassandra Duncan-Azadi, M.D., Amber Brooks, M.D., University of Alabama Birmingham, Birmingham, AL Supraorbital neuralgia although an uncommon disorder is the most frequent extra cranial neuralgia of the trigeminal nerve. There are several small case studies reporting various medical managements and even surgical treatment. However there are few reports of successful treatment with pulsed radiofrequency ablation. We present a 36-year-old female patient who developed debilitating supraorbital neuralgia following a concussion who failed medical management. She underwent two treatments with pulsed radiofrequency ablation and obtained significant relief allowing her to return to work. Pulsed radiofrequency ablation offers a less invasive nonsurgical option for patients with this painful disorder.

Preprocedure vitals were BP 106/72 mmHg pulse 87 bpm pulse oximetry 99% on room air. For the procedure patient was prone without sedation. Under fluoroscopic guidance radiofrequency needles were placed in the proximity of medial branches. Upon initiation of radio frequency lesion at C6 level the patient developed sinus bradycardia that progressed to a 5 second pause. Lesioning was terminated after recognition of bradyarrythmia with gradual return of heart rate to the baseline. Radiofrequency lesioning was attempted two more times with similar bradyarrhythmia. Saturday, October 12 8:00 AM - 9:30 AM PN MC51 Challenging Spinal Cord Stimulator Placement in High-Risk Patient With Critical Limb Ischemia on Antiplatelet Agent Shrif Costandi, M.D., Yashir, Eshraghi, M.D., Hani Yousef, M.D., Ph.D., Yosaf Zeyed, M.D., Youssef Saweris, M.D., Nagy Mekhail, M.D., Ph.D., Cleveland Clinic Foundation, Cleveland, OH, Yashar Eshraghi, Case Western Resrve University/MetroHealth Medical Center, Cleveland, OH Background: Spinal cord stimulation (SCS) has been advocated to treat critical limb ischemia. Antiplatelet might render SCS placement challenging. Case History: Sixty seven years-old male presented with critical limb ischemia. Lumbar sympathetic block produced significant short-term pain relief. SCS trial was done as a two-staged procedure using perioperative eptifibatide. First stage of the trial resulted in 100 % pain relief of his rest pain and improved claudication distance. Second stage followed with implantation of the battery. Conclusion: We are reporting successful and safe use for perioperative eptifibatide infusion while placement of SCS in high-risk vascular patient on preoperative prasugrel. Saturday, October 12 8:00 AM - 9:30 AM PN MC52 Intrathecal Catheter Placement in the Anticoagulated Patient Stephen Estime, Dalia Elmofty, M.D., University of Chicago, Chicago, IL A 13-year-old female with PMH of Neurofibromatosis I complicated by metastatic malignant peripheral nerve sheath tumor was consulted to pain service for chronic abdominal pain. After failing oral and intravenous opioid regimens the decision was made to attempt intrathecal pain management via a continuous catheter. Before catheter placement patient's INR was found to be elevated and expected to continue to rise. After administration of FFP the INR was reduced. Although it is against ASRA guidelines for neuraxial catheter placement in a coagulopathic patient after discussing with patient and family an intrathecal catheter was successfully placed without complications.

Three weeks prior the patient had undergone an uncomplicated ileocecectomy for an obstructing high grade B cell lymphoma tumor. Laparotomy revealed no signs of bowel ischemia or perforation but showed omental thickening and a large amount of tumor burden throughout the abdomen. Postoperatively the patient acutely declined and was diagnosed with tumor lysis syndrome that lead to hemolytic anemia acute kidney injury severe metabolic acidosis and methemoglobinemia resulting from Rasburicase therapy. Saturday, October 12 8:00 AM - 9:30 AM CC MC57 Unexpected Vascular Lesions in a Patient With Traumatic Brain Injury Nada Alkaki, Benjamin Moor, Tufts Medical Center, Boston, MA, Yana Hudcova, Lahey Hospital and Medical Center, Burlington, MA We present a case of a previously healthy 61-year-old patient admitted to the SICU with the diagnosis of traumatic right sided acute on chronic subdural hematoma (SDH). Initial CT scan demonstrated lenticular subdural lesion with significant cortical compression and midline shift as well as suspicion for vascular aneurysms at the base of the skull. Patient was treated by evacuation of the hematoma via burr hole. Three days later CT angiography confirmed multiple intracranial aneurysms and patient underwent elective clipping of five and coagulation of three aneurysms. We discuss diagnosis operative options and postoperative care in patients with intracranial aneurysms. Saturday, October 12 8:00 AM - 9:30 AM CC MC58 Acute Non-Hepatic Hyperammonemic Encephalopathy Wesley Allen, M.D., University of Missouri-Columbia, Columbia, MO A 65-year-old female with ESRD on hemodialysis presented to the hospital malnourished with high ileostomy output and failure to thrive. TPN was initiated when traditional supplementation measures failed. Acute decompensation requiring vasopressor support and ETT intubation subsequently ensued. Ammonia level was elevated at 126mmol/dL. After common etiologies of acute hyperammonemic encephalopathy were ruled out acute urea cycle failure was identified secondary to deficiencies in arginine ornithine and citrulline from prolonged high ileostomy output malnutrition and chronic hemodialysis. With scheduled hemodialysis and IV amino acid replacement the patient showed vast clinical improvement and was soon discharged from the hospital.

Shaan Alli, M.D., Peter Wong, M.D., Tufts Medical Center, Boston, MA, Veljko Popov, M.D., Jana Hudcova, M.D., Lahey Clinic, Burlington, MA We present a case of a healthy 19-year-old patient admitted to the surgical intensive care unit following a motor vehicle collision. Initial computed tomography of the patient's brain was unremarkable with the exception of a single punctuate lesion in the left frontal deep white matter. However the patient's neurologic deterioration with progression to coma was inconsistent with initial radiologic studies. Repeated computed tomography and magnetic resonance imaging sequences showed multiple deep white matter foci of hyperdensity findings consistent with diffuse axonal injury. The clinical and radiologic findings disease course and pathophysiology of diffuse axonal injury will be discussed. Saturday, October 12 8:00 AM - 9:30 AM CC MC60 Several Cardiac Arrests Caused By a Massive Pulmonary Embolus. Successful Treatment With Repetitive Trombolytic Therapy. Johnny Andersen, M.D., Camilla Asferg, M.D., Niels Anker Pedersen, M.D., Karsten Skovgaard Olsen, M.Sc., University of Copenhagen Glostrup Hospital, Glostrup, Denmark This case describes a miraculously survival after double administration of thrombolysis to a patient who experienced a hemodynamic significant PE complicated by six fold cardiac arrest. A 52-year-old man had a 5-hour spine surgery. The next day he had several cardiac arrests due to a massive saddle embolus. The pH was for many hours between 6.6-6.9 and he was in no condition to be transported to another facility for surgery. He was anticoagulated which was followed by massive bleeding. He was treated twice with tenecteplase and eventually the pulmonary embolus was completely resolved and he was admitted to rehabilitation. Saturday, October 12 8:00 AM - 9:30 AM CC MC61 Guidewire- Induced Refractory SVT Lovkesh Arora, M.D., David Traul, M.D., Ph.D., Cleveland Clinic Foundation, Cleveland, OH A 47-year-old male with history of paraplegia from MVA and chronic lumbar osteomyelitis s/p lumbar laminectomy with epidural abscess drainage eight weeks ago was scheduled for lumbar iliac fusion. Patient had no significant cardiac comorbidities. After uneventful anesthesia induction guidewire insertion</u> during right internal jugular venous catheterization resulted in supraventricular tachycardia resistant to IV esmolol and precordial thump. The guidewire was withdrawn but SVT worsened into polymorphic ventricular tachycardia warranting CPR and defibrillation</u>. Rhythm converted to sinus bradycardia after a single shock. The remainder of the intraoperative course was uneventful. Postoperatively cardiac enzymes were negative and neurological status was intact.

Patient was POD # 5 after subtemporal cranial decompression for a ruptured right MCA aneurysm. Open thorocotomy was performed and chest tube was found to be in the left ventricle. Left ventriculotomy was repaired by cardiac surgeon. Patient was transferred back to SICU. Case is being presented for discussion of resuscitation of massive hemorrhage and administration of massive transfusion protocol. Patient underwent an uneventful cranioplasty and closure of the skull two months after discharge. Saturday, October 12 8:00 AM - 9:30 AM CC MC63 Postoperative Management of Severe Acute Anemia in a Jehova's Witness Liana Maria Azi, Ph.D., Fernando Lopes, M.D., Jyrson Klamt, M.D., Ph.D., Luis Garcia, M.D., Ph.D., USP Medicine Faculty of Ribeirao Preto, Ribeiao Preto - SP, Brazil We report severe anemia case succeeding scoliosis surgery in a young Jehovah's Witness patient. Several technics were used to minimize intraoperative blood loss. After surgery she was extubated with hematocrit level of 14% but excessive blood drainage dropped her hematocrit level to 8 6%. Despite hemodynamic deterioration she was awake and refused transfusion. Two hours later her hematocrit was 5% (hemoglobin 1 4 g.dl-1). Then she lost conscious her trachea was intubated and aggressive erythropoietin therapy initiated. After five days she was extubated without organic dysfunction. It's a challenging case because her critical point of DO2 is lower than previously thought possible. Saturday, October 12 8:00 AM - 9:30 AM CC MC64 Multi-Disciplinary Care of a Patient Presenting With Acute Myasthenic Crisis After Major Thoracic Surgery Mark Banks, M.D., Shvetank Agarwal, M.D., Manuel Castresana, M.D., Georgia Regents University, Augusta, GA A 77-year-old male with Osserman's stage III myasthenia gravis (MG) symptomatic for many years but only recently diagnosed presented to the ICU after right thoracotomy decortication and wedge resection for empyema and right-upper-lobe mass. His preoperative FVC and pyridostigmine dose were 3.1 L and 240 mg respectively. Postoperatively he was extubated on second postoperative day (POD). Despite high dose prednisone immunoglubulins pyridostigmine and plasmapheresis progressed to myasthenic crisis requiring re-intubation on POD-3. Continued aggressive supportive care enabled successful extubation on POD-9. This case highlights the role of multi-disciplinary approach to postoperative management of patients with severe MG undergoing major thoracic surgery. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 8:00 AM - 9:30 AM CC MC65 Anticoagulation Dilemma in a Patient With On-X® Mitral and Aortic Valves Tiffany Richburg, M.D., John Beatty, M.D., Abigail Hoffman, M.D., Manuel Castresana, M.D., Shvetank Agarwal, M.D., Georgia Regents University, Augusta, GA A 57-year-old woman underwent On-X® mitral and aortic valve implantations and de Vega tricuspid annuloplasty for severe regurgitation. On postoperative day nine while on subcutaneous heparin and aspirin she developed cardiac tamponade after mediastinal chest tube removal. Following surgical decompression and resuscitation a waxing and waning course of coagulopathy and thrombocytopenia that was exquisitely sensitive to even prophylactic anticoagulation attempts ensued. She progressed to disseminated intravascular coagulopathy requiring multiple blood component transfusions. In this casereport we discuss the clinical dilemma of balancing the need for anticoagulation and managing severe coagulopathy in the context of two freshly implanted mechanical heart valves. Saturday, October 12 8:00 AM - 9:30 AM CC MC66 Use of Salvage Therapy in a Pregnant Patient With Pulmonary Hypertension Meena Bhatia, M.D., Anthony Delacruz, M.D., Rush University Medical Center, Chicago, IL The patient is a 25-year-old female who presented 25 weeks pregnant with shortness of breath and hemoptysis. She was found to have severe pulmonary hypertension with pulmonary hemorrhage and rapidly decompensated requiring emergent intubation. The patient went into cardiac arrest and was placed on VA ECMO. The patient's respiratory status continued to deteriorate and she developed severe ARDS. She was placed on HFOV and slowly started to improve. After 11 days the patient was weaned back to conventional ventilation and de-cannulated from ECMO. The patient continued to improve with decreasing respiratory support and was transferred for acute rehabilitation. Saturday, October 12 8:00 AM - 9:30 AM CC MC67 Percutaneous Tracheostomy and Mechanical Ventilation in the Treatment of Pickwickian Syndrome Daniel Borman, Jackson Memorial Hospital, Miami Beach, FL PG is a 43-year-old African American female with a past medical history of obesity hypoventilation syndrome pulmonary hypertension systemic hypertension asthma and multiple dvt's. The patient has a long standing history of obstructive sleep apnea leading to severe pulmonary hypertension and right heart failure. The patient was treated with home oxygen BiPAP and oral medications however she presented to a local community hospital obtunded due to apparent carbon dioxide induced narcosis. It was determined that the patient would benefit from a tracheostomy under general anesthesia allowing for more aggressive treatment of the patient's disorder.

Saturday, October 12 8:00 AM - 9:30 AM CC MC72 Hyperfibrinolysis in Therapeutic Hypothermia After Cardiac Arrest Thomas Christianson, J. Russell Langdon, M.D., University of Tennesse Medical Center-Knoxville, Knoxville, TN A 60-year-old female presented to the intensive care unit after two episodes of witnessed PEA arrest with proper ACLS management. The longest episode of PEA lasted roughly 25 minutes. On admission the patient had a GCS of 6T and was requiring vasopressive support. The patient was started on therapeutic hypothermia. Upon reaching target temperature a thromboelastogram was drawn which showed normal coagulation. Twelve hours later a repeat thromboelastogram showed hyperfibrinolysis. Concurrently the patient developed hematochezia worsening hypoxemia despite maximal ventilation efforts and severe hypotension despite multiple vassopressive agents. The family decided to withdraw care at that time. MCC Session Number – MCC02 Saturday, October 12 10:30 AM - 12:00 PM NA MC73 Transient Ischemic Attack (TIA) After Shoulder Arthroplasty in the Beach Chair Position Madeel Abdullah, Anna Irwin, M.D., George Hsu, M.D., Thomas Jefferson University, Philadelphia, PA A 64-year-old man presented for a right shoulder rotator cuff repair. He had an interscalene block followed by general anesthesia during the surgery. The patient was placed in the beach chair position. Phenylephrine boluses were used intermittently throughout the case to maintain mean arterial pressures greater than 75mm Hg. In the PACU the patient suffered a Transient Ischemic Attack (TIA) 2 hours after the surgery ended with right sided weakness dysarthria and deviation of the tongue which resolved in 1.5 hours.

Saturday, October 12 10:30 AM - 12:00 PM NA MC77 Sudden Loss of Unilateral Lower Extremity SSEP's During Spinal Surgery: Review of Causes Kamyar Bahmanpour, M.D., Ramsis Ghaly, M.D., Advocate Illinois Masonic Medical Center, Chicago, IL A 34-year-old male was brought to operation room for right L5-S1 microdiscectomy. After induction of general anesthesia and SSEP electrodes placement patient was positioned prone-kneeling on an Copyright © 2013 American Society of Anesthesiologists Andrews frame and surgery started with a balanced anesthesia and normal SSEP's findings initially. However SSEP's amplitude of the left posterior tibial nerve lost gradually. Possible systemic and surgical causes ruled out immediately and finally the patient was taken out of the kneeling position and SSEP's amplitude returned to normal. The patient repositioned into a less kneeling and procedure continued uneventful. Post operative neurological assessment was normal. Saturday, October 12 10:30 AM - 12:00 PM NA MC78 Acute Subdural Hematoma in PACU Patient After Cochlear Implant Surgery Harish Bangalore Siddaiah, M.D., Ashok Rao, M.D., Shilpadevi Patil, M.D., LSUHSC, Shreveport, LA 65-year-old patient scheduled for a right sided cochlear implant surgery was induced with fentanyl propofol succinylcholine and anesthesia was maintained with isoflurane. Surgery was uneventful however at emergence patient was not responsive to commands had no head lift but had a normal train of four ratio. After ruling out pharmacological metabolic abnormalities patient was shifted to PACU intubated with probable diagnosis of retention of residual anesthestic gas isoflurane vs neurologic abnormality. Patient deteriorated further in PACU had unequal pupil sizes developed extensor posturing CT scan showed acute large subdural hematoma with midline shift which was evacuated immediately. Saturday, October 12 10:30 AM - 12:00 PM NA MC79 Intrathecal Baclofen Pump Malfunction Challenges of Management of Patients With Multiple Sclerosis Withdrawal Syndrome Versus Baclofen Overdose Anna Barczewska-Hillel, M.D., St. Luke's-Roosevelt Hospital Center, New York, NY A 23-year-old female with h/o Multiple sclerosis for 3.5 years(gait instability RLE spasticity and weakness urinary incontinence) was scheduled for revision of malfunctioning baclofen pump. Family noticed worsening of spasticity over 10 days. GA was induced uneventfully and at the end of the procedure patient was extubated after following commands. In recovery room she became unresponsive with increased spasticity tachycardia and hypertension. Saturday, October 12 10:30 AM - 12:00 PM NA MC80 Challenging Monitored Anesthesia Care in a Patient With Carcinoid Tumor Encasing the Carotid Artery Zhe Chen, M.D., Patrick McCormick, M.D., Irene Osborn, M.D., The Mount Sinai Medical Center, New York, NY 56-year-old man with metastatic lung carcinoid status post pneumonectomy presented with neck pain and was found to have a 4x7 cm carcinoid tumor encasing the right common carotid. The patient came for a balloon test occlusion study in neuroradiology. An octreotide infusion was started in the preoperative holding area. Patient was sedated using midazolam and fentanyl but kept conscious for neurologic examinations. A nitroprusside infusion was used to induce hypotension for the study. After a successful BTO the right common carotid was coiled. The patient remained stable throughout the procedure and was discharged to the neurosurgical ICU on octreotide. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM NA MC81 Loss of Intraoperative Evoked Potentials During Resection of a Mediastinal Mass Saranya Chinnappan, M.D., Cindy Wang, M.D., Muoi Trinh, M.D., Mount Sinai Hospital, New York, NY A 45-year-old male presented with a posterior mediastinal mass extending into thoracic vertebrae requiring a posterior laminectomy and thoracotomy. During the laminectomy diminished MEP and SSEP signals were identified but improved with etomidate. The tumor was removed via thoracotomy and MEP was lost again without return with a second etomidate dose. Cord perfusion was increased with phenylephrine and steroids were administered. A wake-up test performed at the end of the 12-hour procedure demonstrated intact sensation but loss of motor function. Motor function eventually improved. This case challenged us to respond to changes in intraoperative monitoring signals to prevent neurologic deficits. Saturday, October 12 10:30 AM - 12:00 PM NA MC83 Isolated Spinal Artery of Adamkiewicz Rupture Presenting as Acute Paraplegia and Severe Hemodynamic Instability Linda Chung, M.D., Candice Burrier, M.D., University of Illinois, Chicago, IL Isolated Spinal Artery Aneursyms (SAA) are rare phenomenon with less than 20 reported cases worldwide. Our case report is of a 22-year-old healthy male with sudden severe chest and neck pain rapidly progressing to complete paralysis of the lower extremities. A CT demonstrated cerebral subarachnoid bleeding and blood around the spinal cord at T7. The patient was hemodynamically unstable with sinus tachycardia malignant hypertension and ST segment changes. Prior to induction of anesthesia for angiography the patient became altered. Spinal angiogram revealed a ruptured T7 artery of Adamkiewicz aneurysm. We will discuss anesthetic considerations of this unique case. Saturday, October 12 10:30 AM - 12:00 PM NA MC84 Remifentanil-Induced Respiratory Failure in PACU After a Brainstem Tumor Debulking: A Word of Caution and Review of Remifentanil Laura Duling, M.D., Annette Rebel, M.D., Grace Liu, B.A., Jeremy Dority, M.D., University of Kentucky, Lexington, KY A 66-year-old man developed sudden apnea and unresponsiveness after a large cerebellopontine angle tumor debulking. Based on the findings of a focused neurologic exam the patient was emergently mask ventilated with subsequent return of spontaneous ventilation minutes later and recovery without further complications. Remifentanil bolus from residual infusion in an IV line was suspected due to rapid return to baseline and acute neurologic findings. We review remifentanil and highlight a challenging diagnostic dilemma in an acutely apneic patient after major neurosurgery. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM NA MC86 Recurrent Stridor After Ependymoma Resection Elizabeth Embury, M.D., Letha Mathews, M.B. B.S., Vanderbilt, Nashville, TN A 31-year-old male presented with a chief complaint of worsening diplopia. CT and MRI imaging revealed hydrocephalus with a cystic mass filling the fourth ventricle. He underwent an uneventful twelve hour posterior fossa craniectomy with resection of an ependymoma. He was successfully extubated at the case end but required reintubation for stridor and respiratory distress on PODs one three and four leading to tracheostomy. Direct laryngoscopy revealed no significant laryngeal edema and calcium levels were normal. His symptoms were thought to be secondary to recurrent laryngeal nerve palsy from traction on the vagus nerve intraoperatively. Saturday, October 12 10:30 AM - 12:00 PM NA MC87 Anesthetic Management of a Patient With Recurrent C2 Chordoma and Metastasis to T3 Presenting for Wide Local Excison and Anterior/Posterior Fusion. Andrew Feldman, M.D., Scott Blackwell, D.O., San Antonio Uniformed Services Health Education Consortium, Ft Sam Houston, TX A 57-year-old female with history of a C2 chordoma was found to have recurrence and T3 metastasis. She had undergone C2 chordoma excision and posterior spinal fusion from occiput-C7 four years prior. This was complicated by airway swelling requiring emergent tracheostomy. She presents with significant sleep apnea and stridor but no neurological deficits. The patient underwent 12+ hour staged procedures: 1) T3 vertebrectomy with wide local excision and revision posterior spinal fusion occiput-T7 and on POD#5 2) Tracheostomy and transoral C2 vertebrectomy with anterior fusion. Anesthetic challenges included airway management one-lung ventilation and the use of SSEPs and MEPs. Saturday, October 12 10:30 AM - 12:00 PM NA MC88 Subarachnoid Haemorrhage Complicated by Severe Neurocardiogenic Shock Michael Bokoch, M.D., Thomas Fernandez, M.B.Ch.B., UCSF, San Francisco, CA A 47-year-old male was admitted with severe SAH shock and hypoxaemic respiratory failure. CXR suggested ARDS. Labs revealed a PO2 of 55mmHg Troponin 10.72ug/L. Echocardiogram showed EF 30% and global hypokinesis. CT angiogram revealed a left supraclinoid ICA blister aneurysm bilateral skull base ICA dissections and evidence of fibromuscular dysplasia. Further cardio-pulmonary stabilization was allowed prior to aneurysm clipping and extracranial-intracranial bypass. Surgery proceeded on vasopressors with a PA catheter guiding fluid therapy. Postoperatively the patient deteriorated with new areas of infarct requiring decompressive craniectomy. He made some improvement yet remains hospitalized with high risk of poor neurologic outcome.

His son also had a pheochromocytoma excised. The patient started experiencing intermittent worsening back and chest pain palpitations and headaches. Cardiac causes were ruled out. Eventual spine CT showed a mass at T4 and MRI confirmed cord compression. The mass was embolized and excised via thoracic laminectomy and fusion. During mass excision bleeding and hemodynamic instability ensued. Urgent anesthetic and interdisciplinary management of a T4 mass compressing the spinal cord is discussed. Saturday, October 12 10:30 AM - 12:00 PM NA MC90 Susceptibility of Motor-Evoked Potentials to Dexmedetomidine During Spine Surgery Ju Gao, M.D., Carl Lo, M.D., Colin Wilson, M.D., West Virginia University, Morgantown, WV A 41-year-old male s/p MVC sustained multiple injuries including occipital cervical dislocation and underwent emergent C2-3 fusion with SSEP and MEP monitoring. The anesthetic included: Sufentanyl 0.3mcg/kg/hr IV Isoflurane 0.5 MAC and Dexmedetomidine 0.5 mcg/kg IV bolus over 10 minutes followed by 0.4 mcg/kg/hr infusion. The patient was placed in the prone position during dexmedetomidine bolus. After prone positioning the patient's upper and lower MEP's could not be detected despite maximal stimulation.

Hindsight Provides Valuable Insight Mari Baldwin, St. Lukes Roosevelt, New York, NY, Gerald Bushman, M.D., Childrens Hospital Los Angeles, Los Angeles, CA We describe the case of a patient scheduled for pericardial window in our institution where cardiac and interventional services are not available. He had an extensive cardiac history and we were concerned he would need some cardiac intervention that we could not provide-yet the surgeon assured this was not so. After surgery he did decompensate and required transfer to our sister hospital with cardiac services. This case points out that there should be better collaboration and communication with surgical colleagues and OR team regarding best patient care and safety before surgery. Should transfer should have occurred prior to surgery? Saturday, October 12 10:30 AM - 12:00 PM PI MC109 Chaos in Off-Site: Bringing the Patient Back to Our Safe Zone Melissa Flanigan, D.O., Sarah Kadhim, M.D., West Virginia University, Morgantown, WV Interventional radiology aneurysmal coiling is one of our offsite assignments. A standard general anesthetic with arterial line is usually performed. In this particular scenario there was undetected closure device failure that led to severe hemorrhagic shock. Radiology team did not intervene so the anesthesia team transferred the patient to our main operating room in order to adequately resuscitate. Since the patient was continuing to decompensate vascular surgery was emergently consulted by the anesthesiologist to remedy the situation. A stent was placed artery repaired and stabilization followed. Clearly vigilance teamwork and insistence by the anesthesia team saved this patients life. Saturday, October 12 10:30 AM - 12:00 PM PI MC110 Difficult Airway Management - An Alternative Approach Pedro Freire, Mariana Correia, Iria Figueira, Nidia Goncalves, Nicolas Zwolinski, Centro Hospitalar Lisboa Ocidental, Lisboa, Portugal A 51-year-old man with a psychiatric illness was proposed to urgent surgical drainage of a gluteal abscess. The patient who presented with dysphonia had a cervical mass (supposed abscess) that extended all the way to the mediastinum conditioning a leftward deviation and compression of the trachea and limited neck mobility with no surgical indication. Coagulation and infection parameters prevented a neuro-axial block. Plans for the anesthetic approach included dissociative anesthesia and awake fiber optic intubation. After careful consideration risks were explained to the patient and the surgery was made under dissociative anesthesia. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM PI MC111 Greening the Operating Rooms (ORs) Sabina Khan, M.D., Joshua Chance, M.D., M.Saif Siddiqui, M.D., University of Arkansas for Medical Sciences, Little Rock, AR, Joe Knight, Arkansas Children Hospital, Little Rock, AR ORs (Operating Rooms) are some of the most waste generating places in a hospital. This has contributed towards the increasing trend of natural disasters. Greening the OR helps identify hospital waste categorization reduces non-regulated waste conserves energy and minimize the exposure patients and public have to hazardous chemicals. By modifying the anesthetic practices we can reduce the eco footprint and lead to the formation of dynamic learning community for information exchange through awareness and education and save millions of dollars by implementation of relevant strategies. A greener health care delivery will have a positive impact on environmental sustainability. Saturday, October 12 10:30 AM - 12:00 PM PI MC112 Massive Transfusion and Refractory Hypotension With Calcium Drug Shortage: What To Do? Tiffany Moon, M.D., Chen Shi, M.D., Anna Allred, M.D., UT Southwestern, Dallas, TX Drug shortages are becoming more common with over 40 intravenous medications listed in 2010. Shortages of certain drugs pose a threat to the optimal treatment of patients especially when acceptable alternatives are unavailable. Here we present the case of a patient with cirrhosis undergoing an orthotopic liver transplant requiring massive transfusion (90 units) and exhaustion of the pharmacy's calcium chloride supply. Resource utilization strategies were employed to open the crash carts on the medical floors to obtain more calcium. This highlights the need for awareness of drug shortages and methods to obtain drugs that are crucial to optimal anesthetic management. Saturday, October 12 10:30 AM - 12:00 PM PI MC113 Emergent Craniotomy for Intracerebral Bleed in a Critically Ill Patient With LVAD Driveline Related Sepsis and Supratherapeutic INR: A Case of Futile Care Amanda Moraska, M.D., Paul Kempen, M.D., Cleveland Clinic Foundation, Cleveland, OH A 59-year-old obese male with hypertension OSA atrial fibrillation on warfarin CVA MI paroxysmal VT smoking alcoholism and heart failure with LVAD placement as a bridge-to-transplant was admitted for driveline-related sepsis. Hospitalization was complicated by extensive intracerebral hemorrhage from supratherapeutic INR. Emergent craniotomy was done under general anesthesia. Post-operatively he had no neurologic improvement and after two additional weeks of expensive tests and procedures further care was deemed futile and withdrawn. This patient illustrates a variety of anesthetic challenges as well as ethical issues concerning futile care something important to consider with medicine's increasing emphasis on resource allocation. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM RA MC114 t-PA Administration for Pulmonary Emboli After Spinal Anesthesia Brian Adams, University of Tennessee Medical Center- Knoxville, Knoxville, TN A 39-year-old female who underwent cesarean section for breech fetal presentation received t-PA within 30 hours of spinal anesthesia due to diagnosis of bilateral pulmonary emboli. While fibrinolytic administration was appropriate based on hemodynamic compromise and presence of right heart strain use of t-PA is considered higher risk for 10 days after neuraxial anesthesia per ASRA guidelines. The use of t-PA was fortunately discovered during routine post-operative rounds at which time the patient was educated on potential complications and neurological checks ordered for 24 hours. Patient follow-up at discharge and within 1 week of discharge revealed no anesthetic-related complication. Saturday, October 12 10:30 AM - 12:00 PM RA MC115 Chronic Pain Localized to the Lliohypogastric Nerve: Treatment Using an Ultrasound Guided Technique of Hydrodissection for Catheter Placement as a Guide for Surgical Lliohypogastric Nerve Resection Adam Adler, M.D., M.S., Pranay Parikh, M.D., Baystate Medical Center, Springfield, MA, Daryl Smith, M.D., University Of Rochester, Rochester, NY A 58-year-old female was referred to the pain service complaining of burning right lower abdominal pain for two years. Iliohypogastric nerve blocks were performed using ultrasound guidance. This was repeated three times after the initial block provided 100% pain relief lasting approximately 4 weeks. A fluoroscopic guided Iliohypogastric nerve cryoablation provided complete pain resolution lasting 4 weeks however with complete return of symptoms. She decided to proceed with surgical excision of the right Iliohypogastric nerve. The technique of hydrodissection was employed to isolate the Iliohypogastric and a catheter was places adjacent to the nerve as a marker for the surgeon. Saturday, October 12 10:30 AM - 12:00 PM RA MC116 Bilateral Transversus Abdominus Plane (TAP) Blocks and Their Role in Facilitating Extubation in a Patient With Intracranial Hypertension Adam Antflick, D.O., George Williams, M.D., Jaideep Mehta, M.D., M.B.A., Bic Chau, M.D., University of Texas Health Science Center at Houston, Houston, TX A 20-year-old Hispanic post-partum female with a past medical history significant for autoimmune hemolytic anemia and pre-eclampsia presented with an intracranial hemorrhage and interventricular hemorrhage who on post-operative day #2 following a caesarean section continued to have increased intracranial pressure. The patient had bilateral TAP blocks in order to provide analgesia and thus reduce intracranial pressure facilitating extubation. Saturday, October 12 10:30 AM - 12:00 PM RA MC117 Continuous Popliteal and Femoral Nerve Catheters in a Patient With Refractory Lower Extremity CRPS Camellia Asgarian, M.D., Priya Kumar, M.D., Candra Bass, M.D., UNC Hospital, Chapel Hill, NC Complex regional pain syndrome (CRPS) is a disease process with debilitating consequences. We describe the case of a 19-year-old woman with a two year history of CRPS type 1 involving her left lower Copyright © 2013 American Society of Anesthesiologists extremity. She was severely debilitated and refractory to conventional therapy including lumbar sympathetic block intravenous ketamine rehabilitation therapy spinal cord stimulation opioids tricyclic antidepressants anticonvulsants and psychotherapy. Our intervention with continuous popliteal and femoral nerve catheters allowed for her participation in physical therapy. As a result she achieved a lower pain score an increased range of motion in her lower extremity and an improved quality of life. Saturday, October 12 10:30 AM - 12:00 PM RA MC118 Use of Regional Anesthesia in a Patient With a Pre-Existing Neuropathy Alisha Bhatia, M.D., Taruna Penmetcha, M.D., John H. Stroger Hospital, Chicago, IL Patient is a 44-year-old male who presented with wrist pain and was found to have a chronic scaphoid fracture five years after an ORIF of the initial injury. He had the hardware removed but continued to have pain. He then developed numbness of the fourth and fifth digits and forearm pain. An EMG showed left ulnar neuropathy across the elbow segment. When he presented for cubital tunnel release decision was made to do a supraclavicular block for anesthesia for the case. The patient continued to have pain and numbness post-op and developed triceps muscle twitching and fasiculations. Saturday, October 12 10:30 AM - 12:00 PM RA MC119 Transversus Abdominis Plane Block in a Patient With Spinal Muscular Atrophy Shelly Borden, M.D., Bridget Muldowney, M.D., Kristopher Schroeder, M.D., University of Wisconsin, Madison, WI A 21-year-old female patient with Spinal Muscular Atrophy (SMA) underwent cystectomy for spastic bladder. She complained of 10/10 pain POD1; epidural was not safe or viable given spinal hardware for scoliosis. She remained intubated postoperatively (difficult intubation history); narcotics were used sparingly to avoid compromising ventilation. TAP block was offered and provided excellent analgesia (2/10). Extubation occurred on POD3. Atrophied abdominal musculature in SMA made the block technically challenging but was successful and should be considered an alternative method for postoperative pain management in patients undergoing abdominal surgery in whom neuraxial analgesia is contraindicated and narcotics are avoided. Saturday, October 12 10:30 AM - 12:00 PM RA MC120 Peripheral Nerve Blockade as Primary Anesthetic for Total Knee Arthroplasty in Anticoagulated Patient With Severe Ischemic Cardiomyopathy Clifford Bowens, M.D., Jeremy Jones, M.D., Vanderbilt University School of Medicine, Nashville, TN We report a case in which peripheral nerve blockade was considered the safest anesthetic for a patient undergoing total knee arthroplasty. The patient's past medical history was significant for CHF (EF = 10%) ischemic cardiomyopathy (AICD) and atrial fibrillation. The patient had been anticoagulated with warfarin and enoxaparin. Ultrasound guidance was used to perform a continuous femoral nerve block lateral femoral cutaneous nerve block and obturator nerve block. A nerve stimulation technique was used for the sciatic nerve block. The patient was maintained on a dexmedetomidine infusion during the surgery and had an uneventful intraoperative and postoperative course. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM RA MC121 Combined Spinal Epidural Anesthesia for Non-Pheochromocytoma-Related Ambulatory Surgery in a Patient With Metastatic Pheochromocytoma Sheida Bunting, M.D., Eric Brumberger, M.D., New York Presbyterian/Weill Cornell, New York, NY The literature is sparse regarding the use of neuraxial anesthesia in patients with pheochromocytoma. A limited number of case reports describe the intentional use of epidural anesthesia as the primary anesthetic in patients with pheochromocytoma undergoing non-pheochromocytoma-related surgery. We present a successful case of a patient with metastatic pheochromocytoma undergoing resection of a femoral osteochondroma performed under spinal anesthesia using combined spinal-epidural and sedation in an ambulatory setting; this technique has not been previously reported. We conclude that the dense sympathectomy and hemodynamic stability resulting from spinal anesthesia make it an ideal option for patients with pheochromocytoma undergoing non-pheochromocytoma surgery. Saturday, October 12 10:30 AM - 12:00 PM RA MC122 Supraclavicular Nerve Block Unmasks Myocardial Infarction Sneha Chandra, M.D., Michael Bassett, M.D., MetroHealth Medical Center, Cleveland, OH A 90-year-old female presented with intracranial hemorrhage and non-displaced right proximal humerus fracture and non-operative management was recommended. The acute pain service was consulted for management of shoulder pain and performed a right supraclavicular nerve block. Immediately following the procedure she reported resolution of shoulder pain but complained of abdominal pain and dyspnea. She became anxious tachypneic and tachycardic with decreasing oxygen saturation and ST segment depression. Secondary to the temporal nature of her symptoms there was immediate concern for phrenic nerve paralysis pneumothorax and/or local anesthetic systemic toxicity. After further evaluation and testing she was diagnosed with NSTEMI. Saturday, October 12 10:30 AM - 12:00 PM RA MC123 Epidural Blood Patch for Presumed Post Dural Puncture Headache After Posterior Spinal Fusion Surendrasingh Chhabada, M.D., Pilar Castro, M.D., Markakis Dorothea, M.D., Cleveland Clinic Foundation, Cleveland, OH A 14-year-old female with idiopathic scoliosis who underwent T5-L1 posterior spinal fusion presented as an outpatient one week post-operatively with severe postural headache. No neuroaxial techniques had been performed perioperatively. She was admitted to the hospital overnight one week after discharge with suspected post dural puncture headache (PDPH) which was successfully treated conservatively with hydration caffeine and bedrest. She required readmission however two weeks post-operatively with recurrent symptoms of PDPH. Despite an unknown level of dural puncture we decided to treat her with a lumbar epidural blood patch which resulted in immediate and permanent resolution of PDPH symptoms. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM RA MC124 Spontaneous Complete Resolution of Paraplegia Caused by Large Epidural Hematoma Associated With Epidural Anesthesia in a Vascular Surgery Patient Jae-Young Kwon, Ah-Reum Cho, Jeong-Min Hong, Mi-Jung Cho, Pusan National University Hospital, Busan, Republic of Korea A 76-year-old woman taking antiplatelet agents (aspirin clopidogrel) due to coronary stent placement underwent femoropopliteal revascularization under epidural anesthesia. She had claudication caused by arteriosclerosis obliterans and spinal stenosis. The antiplatelet agents were discontinued 7 days before the surgery and were bridged over to intravenous unfractionated heparin until 6 hours before the surgery. Epidural anesthesia and femoropopliteal revascularization were performed without any problems. The patient developed paraplegia 11 hours after surgery. The MRI showed large epidural hematoma extended from T2 to L4 levels. Despite our recommendation the surgical decompression was refused. However complete recovery occurred in 14 days. Saturday, October 12 10:30 AM - 12:00 PM RA MC125 What Goes Up Must Come Down: The Case of Cardiac Arrest & Complete Heart Block During Spinal Anesthesia Mack Thomas, M.D., Sharon Couch, M.D., Ochsner Medical Center, New Orleans, LA Although 1st degree AV blocks and infranodal conduction defects are not considered contraindications to neuraxial anesthesia they may pose risk in developing higher degree AV blocks or cardiac arrest. We describe a case of a 73-year-old woman with a complicated history including RBBB syncopal episodes attributed to BPPV and 1st degree AV block who presented for TKA. Minutes following hyperbaric spinal anesthesia initiation patient suffered severe bradycardia which progressed to complete heart block and cardiac arrest. Prompt resuscitation was performed with resolution of cardiovascular collapse. Resultant cardiac rhythm revealed complete heart block which persisted after recession of spinal block. Saturday, October 12 10:30 AM - 12:00 PM RA MC126 Virtual Reality for Ultrasound-Guided Regional Anesthesia - Our Experience Paul Courtney, M.D., Daneshvari Solanki, M.D., Rene Przkora, M.D., Ph.D., University of Texas Medical Branch, Galveston, TX Introduction: Ultrasound-guided regional anesthesia requires coordination between the display of the target on the ultrasound screen and the hands of the physician. We introduced a head-mounted video display (HMD) to display the ultrasound image close to the physician`s eyes and evaluated this approach in a case series. Methods: After IRB approval the HMD was used in 4 patients and compared to 4 patients without HMD for lower extremity blocks. Results: Significant fewer head movements were observed with the HMD. No complications noted. Conclusion: Virtual reality using the HMD improved coordination. A larger study is currently conducted to evaluate these findings. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM RA MC127 Total Spinal Anesthesia: A Devastating Complication of Thoracic Paravertebral Block. Implications of the Anatomical Communications With the Paravertebral Space Craig Cummings, M.D., Medical College of Wisconsin, Milwaukee, WI 52-year-old obese female with multiple bilateral rib fractures and mild traumatic brain injury on therapeutic anticoagulation for prosthetic mitral valve. Pharmacological analgesia ineffective including sub-hypnotic ketamine. No epidural given coagulation status plan for paravertebral catheters. Ultrasound guidance unsuccessful. Classic landmark technique utilized for uneventful placement of bilateral T4 catheters. Negative test dose and aspiration. Incremental injection of 20 mL 0.5% ropivacaine with epinephrine into right catheter. Patient unresponsive with progressive hypoxia hypotension and bradycardia. ACLS performed with chest compressions and medications. Vital signs stable without further hemodynamic support. Patient unresponsive for two weeks off sedation on mechanical ventilation. Saturday, October 12 10:30 AM - 12:00 PM RA MC128 Management of a Rare Femoral Nerve Block Complication Involving Extravasation of Body Fluid in an Elderly Patient Thuan Dao, M.D., Natalie Wong, M.D., Mahammad Hussain, M.D., UT Houston Medical School, Houston, TX Peripheral nerve blocks (PNB) can alleviate perioperative pain decrease narcotic requirement and improve rehabilitation. Management of rare complications of PNBs has not been extensively published. We placed a femoral nerve block catheter in our elderly patient who underwent distal femur ORIF for periprosthetic fracture. Postoperatively 1400 ml of fluid drained from the nerve block site after catheter removal. The block needle could have punctured the bladder causing urine to track along the catheter path. However comparison of the fluid and urine composition ruled out bladder injury. We suspect the fluid was likely extravasation due to the patient's poor nutrition status. Saturday, October 12 10:30 AM - 12:00 PM RA MC129 Epidural Hematoma Following Thoracic Epidural Catheter Insertion in a Patient With No Risk Factor Karine De Oliveira Dias, M.D., Cleveland Clinic Foundation, Cleveland, OH We describe a case of an Epidural Hematoma on a 34-year-old female otherwise healthy diagnosed with a non-functional Left Upper Lobe carcinoid tumor who presented for Sleeve Lobectomy. Laboratorial values were within normal limits. No anticoagulation drugs were administered. A preinduction T5-T6 epidural catheter was inserted easily and surgery completed in 4 hours. Immediately after extubation patient complained of severe back pain and left lower extremity paresis with preserved sensation was appreciated. Thoracolumbar MRI showed an extradural hematoma and spinal cord compression at T5-6. Patient underwent emergent Laminectomy and discharged on PO7 with LLE motor strength 4/5. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 10:30 AM - 12:00 PM RA MC130 Liposomal Bupivacaine Lauren Dies, M.D., Jaideep Mehta, M.D., Gokul Thimmarayan, M.D., Muhammad Hussain, M.D., UT Health Science Center Houston, Houston, TX The anticipation of an extended release local anesthetic agent in regional anesthesia is to provide long acting postoperative pain control without the requirement of a catheter while also decreasing postoperative opioid requirement. Liposomal bupivacaine an extended-release form of bupivacaine can provide analgesia for up to 72 hours without having an indwelling catheter. The following case report describes a 33-year-old male who had a single shot sciatic nerve block with liposomal bupivacaine following an open reduction and internal fixation (ORIF) of his left lateral malleolus and experienced excellent post-operative pain relief but a prolonged motor blockade lasting 120 hours. Saturday, October 12 10:30 AM - 12:00 PM RA MC131 Supplemental Superficial Cervical Plexus Block After Supraclavicular Block in a Morbidly Obese Patient for Arthroscopic Shoulder Surgery Robert Doty, M.D., Luminita Tureaunu, M.D., Dorota Szczodry, M.D., Northwestern University Feinberg School of Medicine, Chicago, IL 38-year-old female ASA 2 145kg 157cm BMI 59 scheduled for left shoulder arthroscopy. A low volume ultrasound guided left supraclavicular block with 10mL of 0.5% bupivacaine with 1:300 000 epinephrine was performed pre-op for postoperative analgesia. Anesthesia was maintained with general anesthesia with endotracheal tube. Post-op in PACU the patient complained of 7/10 (VAS) pain in the C4 nerve root distribution. There was no clinical evidence of respiratory compromise. Left ultrasound guided superficial cervical plexus block with 3mL of 0.5% bupivacaine with 1:300 000 epinephrine was performed. The patient reported 0/10(VAS)pain denied dyspnea and was discharged home. Saturday, October 12 10:30 AM - 12:00 PM RA MC132 Utility of Use of a Continuous Peripheral Nerve Catheter for a Patient Presenting With Muscle CrampFasciculation Deneene Doyker, M.D., Ghassan Aljafar, M.D., Lori Circeo, M.D., Baystate Medical Center, Springfield, MA A 48-year-old male with hypertension hypercholesterolemia diabetic neuropathy of bilateral lowerextremities history of bilateral lower extremity compartment syndrome with surgical intervention left foot drop gastric adenocarcinoma with surgical resection lumbar spinal stenosis with chronic low back pain presented with right lower extremity pain muscle cramp and fasciculation similar in presentation to a past compartment-syndrome episodes.

B.S., Massachusetts General Hospital, Boston, MA A 44-year-old African woman with HIV had a low thoracic midline epidural placed prior to general endotracheal anesthesia for open abdominal myomectomy. Aspiration and test dose were negative so epidural boluses of lidocaine were administered intra-operatively. After an uneventful surgery she remained unresponsive exhibiting dysconjugate gaze and lip-smacking movements. Midazolam propofol levetiracetam and intra-lipid were administered after which she became responsive. Following extubation she had a negative head CT and was taken to the ICU. Neurology consult confirmed the diagnosis of local anesthetic toxicity and recommended no further treatment. Within hours the patient returned to baseline neurological function. Saturday, October 12 10:30 AM - 12:00 PM RA MC134 Bilateral Ropivacaine Infused Brachial Plexus Catheters for Postoperative Pain Control in a Trauma Patient Mical Duvall, Veerandra Koyyalamudi, M.D., LSU Shreveport, Shreveport, LA We present a case of a 26-year-old female with bilateral upper extremity fractures after a motor vehicle collision who received bilateral brachial plexus catheters with an infusion of ropivacaine for post-op pain control. Placement of brachial plexus catheters above the clavicle is associated with a high incidence of phrenic nerve involvement and diaphgramatic paralysis. To avoid complications associated with bilateral phrenic nerve blockade we placed bilateral infraclavicular brachial plexus catheters under ultrasound guidance. Saturday, October 12 10:30 AM - 12:00 PM PD MC135 Anesthetic Management of a Neonate With Obstructing Duodenal Web Adam Adler, M.D., M.S., Baystate Medical Center, Springfield, MA, Jessica Bland, M.D., Connecticut Children's Hospital, Hartford, CT A male child born at 36 weeks was born to a mother with preeclampsia and a history of cocaine use throughout pregnancy. At birth he weighed 3.02kg and was noted to have wide spaced nipples tongue tie hypospadias and was devoid of other obvious abnormalities. He was discharged home after two days and returned on the fifth day of life with poor feeding. Upper GI series demonstrated a bowel obstruction due to duodenal web for which he underwent an emergent uncomplicated surgical resection. He will be evaluated by the hospital geneticist for potential associated congenital syndromes. Saturday, October 12 10:30 AM - 12:00 PM PD MC136 Anesthetic Management of an Adolescent With Anti-N-methyl-D-Aspartate Receptor Encephalitis Naila Ahmad, M.D., Patel Ankur, M.D., Brenda McClain, M.D., Saint Louis University, St. Louis, MO The patient is 14-year-old female scheduled for laparoscopic oophorectomy for teratoma associated with anti-NMDA receptor encephalitis. Initial presentation included headaches dizziness and abdominal discomfort. Seizures extrapyramidal movements violent outbursts and loss of consciousness. Laboratory Copyright © 2013 American Society of Anesthesiologists findings were positive for NMDA antibodies. Pelvic CT revealed an ovarian neoplasm. Pre-operative history and physical exam revealed wide swings in blood pressure agitation and dyskinesia. Anesthetic management consisted of induction with Propofol and vecuronium and maintenance with Sevoflorane and morphine. Invasive blood pressure monitoring was performed. No perioperative adverse events occurred. Drug selection rationale for monitoring and planned postoperative care will be discussed.

Anita Akbar Ali, M.D., Hess Robertson, M.D., University of Arkansas For Medical Sciences, Little rock, AR, Hani Hanna, M.D., Edwin Abraham, M.D., Arkansas Children's Hospital, Little Rock, AR A 3-year-old pediatric trauma patient was scheduled for halo vest placement due to C1 instability. An intramedullary femur nail insertion was also planned after halo fixation. Per Neurosurgeon's request patient was kept sedated and spontaneously breathing during halo placement in order to prevent any unintentional neck movement during airway manipulation. After halo fixation and inhaled induction multiple unsuccessful attempts were made with glidescope and fiberoptic scope. Eventually a MAC 2 blade was inserted in the mouth and handle was attached after placement of blade in oral cavity and ETT was placed successfully (figure 1). Saturday, October 12 10:30 AM - 12:00 PM PD MC138 Challenges Encountered in the Anesthetic Management of a Patient With Cornelia de Lange Syndrome Sehar Alvi, M.D., Shvetank Agarwal, M.D., Ranita Donald, M.D., James Mayfield, M.D., Georgia Regents University, Augusta, GA A 21-year-old female with Cornelia de Lange syndrome (CdLS) presented for transvaginal ultrasound and gynecological examination to evaluate her irregular menses. She had severe micrognathia short neck micromelia of extremities and mental retardation. Anticipating a difficult airway decision was made to avoid endotracheal intubation. Intramuscular ketamine was administered in the preoperative holding area followed by assisted mask ventilation with sevoflurane and oxygen in the operating room. Difficult airway cart was kept on stand-by for an emergent endotracheal intubation or establishing a surgical airway if need arose. We discuss the anesthetic challenges in managing a patient with a rare congenital disorder. Saturday, October 12 10:30 AM - 12:00 PM PD MC139 A Case of Neonatal Airway Obstruction Joseph Andre, M.D., Ammar Yamani, M.D., Donald Schwartz, M.D., Baystate Medical Center, Springfield, MA A 2-day-old male evaluated for excision a large nasopharyngeal mass with resulting ball-valve effect. Following uncomplicated delivery he developed cyanosis and desaturation with feeding. MRI revealed a large soft tissue mass in the nasopharynx. He was taken to the operating room with preparation made for possible difficult airway including Glidescope* 2.5mm 3.0mm ETT Nasal airway cut and measured. Desaturation to 85% and a cyanotic episode were successfully managed with judicious use of CPAP. He was induced with sevoflurane and intubated.. After mass resection he was extubated uneventfully. Radiologic images will highlight the discussion of management of neonatal nasopharyngeal masses.

In utero he was diagnosed at 24 weeks via abdominal ultrasound with bilateral hydronephrosis with severe reflux grade 5. Intraoperative management was uncomplicated. However post procedure observation in the pediatric intensive care unit patient was noted to be voiding ~1liter a day and his electrolyte demonstrated dehydration. His medical management included daily fluid replacement therapy as needed. We are going to present his postoperative course including daily urine output electrolytes and significant hemodynamics. Saturday, October 12 10:30 AM - 12:00 PM PD MC141 The Anesthetic Challenges and Perioperative Considerations for the Management of a Toddler With Schinzel-Giedion Syndrome Ahmed Attaallah, M.D., Ph.D., Drew Rodgers, M.D., West Virginia University, Morgantown, WV We present a toddler with Schinzel-Giedion syndrome (SGS) who underwent craniotomy for craniosynostosis. SGS is an extremely rare genetic disorder characterized by mid-face retraction skull anomalies neuro-degenerative features seizures urinary malformations skeletal and genital anomalies severe mental retardation cardiac defects recurrent pneumonias interrupted breathing failure to thrive and developmental delay. SGS patients typically do not live beyond 2 years. We discuss the numerous potential challenges of SGS and share our anesthetic techniques resulting in successful management of our patients. We also review the strategies utilized to avoid and/or treat possible perioperative compromises in order to minimize adverse outcomes. Saturday, October 12 10:30 AM - 12:00 PM PD MC142 Cardiac Arrest After Local Anesthetic Intoxication in a Pediatric Patient Liana Maria Azi, M.D., Ph.D., Ana Amelia Souza Simas, M.D., Anna Gisele Coutinho, Wilfred Tobon, Diego Grimaldi Figueiroa, Professor Edgard Santos University Hospital, Salvador, Bahia, Brazil A 6-year-old 20 kg male presented for hypospadias correction. General anesthesia and caudal block with Bupivacaine 0 375% 10 ml was performed. One minute later he experienced ventricular tachycardia reverted by amiodarone but it subsequently evolved to pulseless electrical activity (PEA). Local anesthetic intoxication was hypothesized and adrenaline and lipid emulsion was administrated followed by continuous infusion of both. He returned to sinusal rhythmus approximately 1 hour after cardiac arrest. The patient was transported to the PICU and successfully extubated after 48h. He was discharged home without any sequelae six days later.

On day of surgery in the OR patient was initially intubated. However there was no chest rise misting or ETCO2 detected suspecting esophageal intubation patient was re-intubated again with same results. A suction catheter was introduced into the ETT and thick mucus plugs were suctioned out. Flexible bronchoscope was used to further determine the cause of ETT obstruction. Thick mucus plugs and blood clots along with few gun pellets were suctioned. Saturday, October 12 10:30 AM - 12:00 PM PD MC144 Right-Sided Eventration Masquerading as RDH Natalie Barnett, M.D., Francine Yudkowitz, M.D., The Mount Sinai Hospital, New York, NY A neonate born at 36 weeks 6 days of a twin gestation with APGAR scores of 8/9 was noted to be tachypneic in the well baby nursery. After transfer to the neonatal intensive care unit pediatric surgey was consulted and a thoracic ultrasound revealed the liver in the right hemithorax. A right sided diaphragmatic hernia was suspected and on day of life (DOL) #4 the neonate was brought to the OR. Surgical finding was diaphragmatic eventration that was repaired without complications. Patient was discharged home on DOL #16 and was doing well at 6 week follow up. MCC Session Number – MCC03 Saturday, October 12 1:00 PM - 2:30 PM FA MC146 Undiagnosed Heart Block In An Out-Of-State Patient Natalie Barnett, M.D., Steven Neustein, M.D., The Mount Sinai Hospital, New York, NY A 76-year-old male patient traveled from Georgia to New York for a parathyroidectomy. Other than hypertension the patient denied any other medical history. Once in the operating room the patient was noted to be in symptomatic second degree heart block. Patient was brought to the PACU and cardiology consulted. Due to the unusual circumstance of an out-of-state patient the decision was made to have a temporary transvenous pacemaker placed and to proceed with the parathyroidectomy later the same evening. The patient was discharged against medical advice prior to permanent pacemaker placement and returned home to Georgia. Saturday, October 12 1:00 PM - 2:30 PM FA MC147 Perioperative Serotonin Syndrome Nicole Beatty, M.D., John Eisenach, M.D., Mayo Clinic, Rochester, MN Serotonin syndrome is gaining attention in perioperative and chronic pain settings due to the growing prevalence of multi-modal therapies that increase serotonin levels and thereby heighten patient risk. A Copyright © 2013 American Society of Anesthesiologists patient's genetic make-up may further add to their risk of serotonin syndrome. Described is a case of serotonin syndrome upon emergence from general anesthesia. A subsequent cytochrome P4502D6 genetic test result suggested a potential alteration in metabolism. We describe the clinical presentation and management of perioperative serotonin syndrome as well as a possible genetic predisposition for this patient taking combination anti-depressant medications and receiving common perioperative medicines. Saturday, October 12 1:00 PM - 2:30 PM FA MC148 An Airway Emergency on Postoperative Day 7 Allan Belcher, D.O., John Doyle, M.D., Ph.D., Maged Gurguis, M.D., Cleveland Clinic, Cleveland, OH A 66-year-old male underwent cervical fusion surgery. He was discharged on POD 5 but readmitted the next day for neck pain. On POD 7 his pain increased significantly his neck was actively swelling and he had respiratory distress. He was taken urgently to the OR awake fiberoptic intubation was attempted but anatomy was poorly visualized and he rapidly desaturated. ENT and the Anesthesia resident urgently opened the left neck wound and expressed 50 cc of clotted blood. Awake Glidescope intubation was used and with marked difficulty he was successfully intubated with a 5.5 MLT tube on 3rd attempt. Saturday, October 12 1:00 PM - 2:30 PM FA MC149 Anesthetic Concerns and Considerations for Arcuate Ligament Syndrome Cole Bennett, M.D., John Jerabek, D.O., Cleveland Clinic Foundation, Cleveland, OH Surgery for arcuate ligament release can be performed via open or laparoscopic. While it has been performed safely laparoscopically the rate of conversion to open is high enough that it should be of significant concern to the anesthesiologist for all patients undergoing this procedure. This case report describe one such instance in which the celiac artery was severed during the procedure and why it is of the utmost importance for the anesthesiologist to prepare for a worst case scenario despite the fact that these patients are often otherwise healthy. Saturday, October 12 1:00 PM - 2:30 PM FA MC150 Anesthetic Concerns for a Myasthenia Gravis Patient Undergoing Robot-Assisted Thoracoscopic Thymectomy Jennifer Bernard, M.D., Alan Romero, M.D., UT Southwestern Medical Center, Dallas, TX A 40-year-old male with myasthenia gravis presented for robotic-assisted thoracoscopic thymectomy. Pre-operatively he was continued on 120mg pyridostigmine TID and 20mg prednisone daily. Anesthesia was induced with remifentanil lidocaine ketamine and propofol initially trying to avoid paralytics. The patient had a difficult airway necessitating administration of rocuronium for placement of a SLT and bronchial blocker. Anesthesia maintenance was achieved with a remifentanil infusion and boluses and sevoflurane. The patient was able to be extubated in the OR after full reversal and demonstration of extubation criteria. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM FA MC151 The Devil in Disguise: Malignant Hyperthermia Phenotypes Francisco Bezerra, M.D., Paras Patel, M.D., Zachary Price, M.D., Henry Ford Hospital, Detroit, MI A 57-year-old male with history of arthritis and hypothyroidism underwent repeat transphenoidal resection of pituitary adenoma. Intravenous general anesthesia was induced and maintained with isoflurane. Approximately 2.5h after induction patient presented gradual increase of temperature EtCO2 and later tachycardia. Malignant hyperthermia was considered. Isoflurane was discontinued and a propofol infusion along with active cooling was installed. Administration of Dantrolene was held due to clinical improvement. Patient was transported to ICU and extubated the same day. Serum CPK peaked at 1631 IU/L. Submission of blood sample for malignant hyperthermia susceptibility testing was positive for heterozygous in the RYR1 gene. Saturday, October 12 1:00 PM - 2:30 PM FA MC152 Not Just Another Biopsy Alisha Bhatia, M.D., John H. Stroger Hospital, Chicago, IL A 29-year-old male with no medical history presented with a productive cough and dyspnea on exertion. CT scan revealed a large mass within the anterior mediastinum extending into the left lung and inducing rightward distal tracheal deviation. There was marked attenuation of the SVC and 40% loss of lung volume. Anesthesia was consulted for sedation for a CT guided biopsy because the patient was unable to lay flat without coughing and feeling short of breath. General anesthesia was administered due to concern for the airway given the size of the mass and its location. Saturday, October 12 1:00 PM - 2:30 PM FA MC153 Anesthetic Considerations for an ALS Patient Undergoing Diaphragm Pacemaker Placement Amar Bhatt, M.D., Joshua Lumbley, M.D., The Ohio State University, Columbus, OH Amyotrophic lateral sclerosis (ALS) is a rare degenerative disease involving both upper and motor neurons eventually causing failure of pulmonary mechanics requiring tracheostomy and full ventilator support. At our institution laparoscopically placed diaphragm pacing systems (DPS) have been trialed for insertion prior to requirement of a tracheostomy and ventilator support. Anesthetic management of this and other procedures on patients with ALS requires careful intraoperative management for successful extubation and ventilator independence. We describe the anesthetic management of a patient with late stage ALS for laparoscopic DPS placement without the use of neuromuscular blockade successful extubation and no further pulmonary consequences. Saturday, October 12 1:00 PM - 2:30 PM FA MC154 Utilization of iPhoneFaceTime™; Application to Facilitate Intraoperative Ultrasound Guided Arterial Line Placement Ryan Bialas, M.D., M.P.H., Claude McFarlane, M.D., UNC Chapel Hill, Chapel Hill, NC Proper patient forearm positioning for placement of a radial arterial catheter is often challenging intraoperatively. When ultrasound guided line placement is necessary intraoperatively it is often Copyright © 2013 American Society of Anesthesiologists impossible to place the ultrasound monitor in a location that can be viewed by the anesthesia provider placing the line. We describe the use of the iPhone and FaceTime™; application to facilitate successful intraoperative ultrasound guided placement of difficult arterial lines in two patients. This technique could be useful in numerous applications when cumbersome ultrasound machines are unable to be placed in an optimal location for the anesthesia provider performing a procedure. Saturday, October 12 1:00 PM - 2:30 PM FA MC155 Awake Emergent Tracheotomy in a Patient With Superior Vena Cava Syndrome Stephen Bird, D.O., Chris Nagy, M.D., SAUSHEC, San Antonio, TX 62-year-old female with history of breast cancer and subsequent subclavian vein catheter placement for chemotherapy presented to the ED with severe neck and upper extremity swelling and worsening dyspnea. Computed tomography of the neck revealed superior vena cava syndrome secondary to catheter related thrombosis. Shortly after admission to the ICU anesthesia was consulted for emergent airway management. Significant edema was noted on the airway exam and the patient's respiratory compromise continued to worsen. After consideration of multiple airway approaches the decision was made to proceed with an awake emergent tracheotomy. This led to immediate improvement in oxygenation. Saturday, October 12 1:00 PM - 2:30 PM FA MC156 Interruption of Dual Antiplatelet Therapy: Anesthetic Management of a Patient With a < 30 Day Old Drug Eluting Stent Undergoing Cranioplasty Gabriel Bonilla, M.D., Mount Sinai School of Medicine - Elmhurst Hospital, Elmhurst, NY A 78-year-old male with hypertension and a bioprosthetic MVR has a < 30 day old drug eluting stent in a CABG graft. Dual antiplatelet therapy has been discontinued because of recurrent subdural hematomas requiring subsequent craniotomy with hematoma evacuation serial bedside aspirations of postoperative fluid collection and craniectomy with hematoma evacuation. He presents for a scheduled cranioplasty. This case reviews maintainance of a favorable balance between factors determining oxygen supply and demand and the different modalities used to monitor perioperative myocardial ischemia. This case emphasizes the importance of interdisciplinary communication when caring for patients in the perioperative setting. Saturday, October 12 1:00 PM - 2:30 PM FA MC157 Airway Management in a Patient with an Epiglottic Cyst Robert Bowers, M.D., Jonathan Lesser, M.D., Franco Resta-Flarer, M.D., Migdalia Saloum, M.D., St Luke's Roosevelt Hospital Center - Columbia University, New York, NY A 42-year-old with a large epiglottic cyst in the vallecula presented for excision. Preoperative nasopharyngoscopy demonstrated the cyst obliterating any view of the glottic opening. Intraoperatively a video Glidescope was used to characterize the anatomy of the cyst and its impact on tracheal access and corroborated the visual obstruction of the glottis. Initial attempts to lift the cyst or displace it laterally with the endotracheal tube were unsuccessful. A decision was made to do direct laryngoscopy with a Miller 2 blade allowing the cyst to be displaced ventrally facilitating intubation with a size 5.0 ETT. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM FA MC158 Airway Fire Inside Rigid Bronchoscope Daniel Brezina, Slawomir Oleszak, M.D., Renata Kowal, M.D., Yelena Babenko, M.D., Stony Brook University, Stony Brook, NY A 70-year-old man underwent bronchoscopy to evaluate hemoptysis. IV induction followed by placement of rigid bronchoscope was accomplished without incident. A RUL carcinoid tumor was resected using electrocautery snare. The patient was then ventilated for 5 minutes on RA followed by application of YAG laser for hemostasis at which time a flame was observed inside bronchoscope. The fire was immediately extinguished and bronchoscope removed. There was evidence of fire damage to the plastic suction catheter but bronchoscopy showed no airway damage. The case was completed and the patient had an otherwise unremarkable postoperative course. Saturday, October 12 1:00 PM - 2:30 PM FA MC159 Anaphylactic Reaction to Antithymocyte Globulin Rabbit During Kidney Transplant Robert Buchmann, M.D., Kyle Dryden, M.D., SLU, St. Louis, MO We present a 41-year-old male for kidney transplant. History included hypertension and end stage renal disease. Pt was taken to operating room anesthesia was induced trachea was intubated and arterial and central lines were placed. Procedure was started without incident. Prophylactic methylprednisone was administered followed by antithymocyte globulin rabbit infusion. Shortly after infusion was initiated patient became hypotensive and peak airway pressures rose drastically causing difficult ventilation. Several epinephrine boluses followed by infusion were started and patient eventually stabilized. Transplant was aborted and patient was transported to ICU. Patient was extubated and epinephrine infusion discontinued post-operative day 2. Saturday, October 12 1:00 PM - 2:30 PM FA MC160 Collapse of a Large Goiter Causing Immediate Respiratory Collapse During a Routine Pre-Anesthetic Assessment Gaurav Budhrani, M.D., Temple University Hospital, Philadelphia, PA A 50-year-old female presents with an 8x6 cm thyroid mass rightward deviation and direct compression of the trachea and extension into the anterior mediastinum. She is symptomatic when supine and is scheduled for surgery. Immediately after the pre-anesthetic evaluation she experiences sudden dyspnea panics and turns cyanotic. A rapid response is called by the RN while anesthesiology calls for backup and a fiberoptic cart. She develops bradycardia and a Code Blue is activated. After BMV with the head of the bed elevated she returns to consciousness. Her airway is topicalized with lidocaine and an awake glidescope intubation is successful. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM FA MC161 Anesthetic Management of a Patient With a Solitary Fibrous Tumor Occupying the Entire Left Hemithorax Presenting for Resection via Anterolateral Thoracotomy and Hemisternotomy Melissa Byrne, D.O., Jennifer Vance, M.D., University of Michigan, Ann Arbor, MI We present the case of a 54-year-old male with past medical history of hypertension and six months of progressive dyspnea on exertion found to have a mass occupying the entire left hemithorax causing rightward mediastinal shift scheduled for left pneumonectomy with possible cardiopulmonary bypass. A highly vascularized tumor weighing approximately 3.5 kilograms was resected with accompanying massive blood loss and hemodynamic compromise requiring volume resuscitation and vasopressor administration. We will discuss the management of altered cardiopulmonary physiology experienced by re-expansion of a lung which had functionally been collapsed for several months preoperatively. Saturday, October 12 1:00 PM - 2:30 PM FA MC162 Airway Management of Patients With Severe Ankylosing Spondylitis William Carter, M.D., Jennifer Vance, M.D., Gennadiy Voronov, M.D., John H. Stroger Hospital of Cook County, Chicago, IL I present a case of a 40-year-old with ankylosing spondylitis who presented for a corrective total hip replacement. He presented with stiffness of the cervical spine atlanto- occipital temporo-mandibular and crico- arytenoid joints. The patient was positioned properly and the King Laryngoscope a form of indirect laryngoscopy was attempted and was successful on the first attempt. An anesthetic plan in which tracheal intubation is accomplished before anesthetic induction or immediately after an expeditious induction needs to be in place before the patient arrives in the OR. There are many options in securing the airway in AS patients. Saturday, October 12 1:00 PM - 2:30 PM FA MC163 Anesthetic Concerns for Posterior Lumbar Fusion in Patient With Undiagnosed Myotonic Dystrophy Courtney Castoro, M.D., Daniel Ferry, M.D., Katalin Scherer, M.D., The University of Arizona College of Medicine, Tucson, AZ Myotonic Dystrophy Type 1 (DM1) is the most common form of neuromuscular disease in adults with a prevalence of 1 in 8 000. It is an autosomal dominant disease caused by a trinucleotide (CTG) repeat in theDMPK gene. Genetic anticipation is a characteristic feature where the disease appears at an earlier age and with increasing severity in successive generations. Anesthetic complications are numerous potentially deadly and not proportional to the severity of the disease. Preoperative screening may be difficult as patients may not know they have the disease- common due to the neuropsychological and personality changes characteristic of DM1. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM FA MC164 Dabigatran in the Setting of Urgent Surgery Dennis Chang, Cleveland Clinic Foundation, Cleveland, OH A 77-year-old male presented with right intracapsular hip fracture after a syncopal episode. Medical history includes severe oxygen dependent COPD rheumatoid arthritis medically managed significant/severe CAD s/p CABG with bioprosthetic Mitral Valve and Tricuspid valve repair sick sinus syndrome/atrial fibrillation s/p MAZE procedure with pacemaker CML with recurrent pleural effusions. He had stage 3 Chronic renal failure (creatinine=) and dabigatran maintenance dose was last ingested 46 hours earlier with preop PT/INR PTT abnormal at ( 17.2/1.5 59). The patient appeared cyanotic with tachypnea on oxygen at 4 l/min reporting this unchanged since the syncope. ABG and Troponin sent. Saturday, October 12 1:00 PM - 2:30 PM OB MC165 High Risk Obstetric Patient With Non-Ischemic Cardiomyopathy and Scleroderma Shayan Bengali, B.S., Mohammed Abdel Rahim, M.D., University of Miami Miller School of Medicine, Miami, FL A 23-year-old gravida 2 para 0-1-0-1 at 28 weeks gestational age presents with 2 weeks of worsening dyspnea. She was admitted into the cardiac ICU and treated for uncompensated CHF. She remained as an inpatient until delivery due to her scleroderma and severely dilated cardiomyopathy with left ventricular non-compaction and poor EF status post cardiac resynchronization therapy. She was found to have an EF of 10% pulmonary edema and restrictive lung disease. The fetus on routine monitoring was found to have recurrent late-decelerations and it was decided the patient would undergo elective repeat cesarean section with cardiopulmonary bypass on standby. Saturday, October 12 1:00 PM - 2:30 PM OB MC166 Acute Hypoxemic Cardiopulmonary Arrest in a Parturient With Severe Preeclampsia and Cardiomyopathy: Anesthetic Management for Unanticipated Emergent Cesarean Delivery John Berry, M.D., Lavinia Kolarczyk, M.D., David Mayer, M.D., UNC Hospitals, Chapel Hill, NC A 25-year-old G3P0 morbidly obese parturient with severe preeclampsia and 25 week twin gestation was intubated for respiratory distress and transferred to our facility. Mechanical ventilation was poorly tolerated and she developed acute hypoxemic bradycardic arrest. Bedside TTE revealed acute cardiomyopathy. She was brought to the OR for emergent caesarean section. Given the broad differential diagnosis for her hemodynamic compromise TEE was requested. TEE revealed large pleural effusions and LVEF 25%. Bilateral chest tubes were placed with immediate improvement in ventilation and oxygenation. This case illustrates the timely effectiveness of a multidisciplinary approach of anesthesia and surgical subspecialties. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM OB MC167 Epidural by Flashlight Daniel Betterly, Brent Luria, M.D., NYU, New York, NY In the obstetrical suite during hurricane sandy with no light besides flashlights there was a 30-year-old parturient. She was 40 weeks pregnant and in active labor. She had 3 previous C-Sections and was attempting to have a vaginal birth. There was no way to effectively monitor fetal heart rate and the mother was on a transport monitor. An epidural catheter was placed with a flashlight in order to provide a safer method incase a C-section was needed and to provide some pain relief during labor. Saturday, October 12 1:00 PM - 2:30 PM OB MC168 Thrombotic Microangiopathy in Pregnancy Robert Biechler, M.D., Medical College of Wisconsin, Milwaukee, WI A 23-year-old African American female without a significant past medical history presented in active labor. An epidural was placed without complications. Labs were ordered two hours following epidural placement. Labs illustrated a platelet count of 6 000. Based on the labs the patient was given the presumed diagnosis of pregnancy induced TTP/HUS. The patient was initially treated with fresh frozen plasma transfusion. Following delivery by cesarian section the patient was treated with plasma exchange and diagnosed definitively with TTP. The case illustrates the difficult management decisions that are required when managing a parturient with newly diagnosed thrombotic microangiopathy. Saturday, October 12 1:00 PM - 2:30 PM OB MC169 Prolonged Paralysis After Spinal Anesthesia in a Parturient: A Cause for Concern Brett Blakeway, M.D., John Carter, M.D., Randall Henthorn, M.D., Abhinava Madamangalam, M.D., University of Oklahoma Health Science Center, Oklahoma City, OK A young gravida at 39 weeks with chronic hypertension Type II DM and obesity underwent a repeat C/S and tubal ligation under a standard spinal anesthetic. Signs and symptoms of lower extremity paralysis persisted hours after normal anticipated recovery. Neurosurgical consultation and extensive investigations including a spine MRI revealed no abnormalities. The patient complained of blindness in both eyes on post-op day 3. Psychiatric evaluation pointed to a conversion disorder. We will detail the diagnosis and management of delayed recovery from spinal anesthesia and describe criteria to diagnose a somatic conversion disorder and management. Saturday, October 12 1:00 PM - 2:30 PM OB MC170 Anesthetic Management of an Exit Procedure Adam Braden, M.D., Christopher Nagy, M.D., San Antonio Uniformed Services Health Education Consortium, Fort Sam Houston, TX A 23-year-old primigravid female presented at term for an Ex-Utero Intrapartum Treatment (EXIT) procedure for severe fetal micrognathia. Following lumbar epidural placement for post-operative pain control the patient's airway was secured with rapid sequence induction and direct laryngoscopy. Further large-bore intravenous access and a radial arterial line were then obtained. Anesthesia was Copyright © 2013 American Society of Anesthesiologists maintained with 1-1.5 MAC desflurane. Profound uterine relaxation was achieved with a nitroglycerine infusion. Maternal blood pressure was supported with phenylephrine. After partial delivery pediatric otolaryngology secured the child's airway without complications. The remainder of the case was uneventful and the patient was extubated without difficulty. Saturday, October 12 1:00 PM - 2:30 PM OB MC171 Management of Placenta Percreta Daniel Brewer, M.D., San Antonio Military Medical Complex, San Antonio, TX A 32-year-old G5P2 female with 2 previous C-sections and history of ruptured ectopic pregnancy presents with placenta percreta. MRI performed at 27 weeks showed invasion into the urinary bladder with potential bilateral ureteral involvement. Patient underwent planned C-section and hysterectomy at 32 +1 weeks with Urologic repair of bladder and cystoscopy for evaluation of ureteral involvement. RSI induction followed large bore IV access and arterial line placement. Central venous access obtained immediately after induction. EBL was 4200ml and patient was resuscitated with 8 units PRBC & FFP. Patient was adequately resuscitated and extubated following procedure. Saturday, October 12 1:00 PM - 2:30 PM OB MC172 Roc Sux or Mag: A Case of Postoperative Paralysis Bridget Bush, Virginia Mason Medical Center, Seattle, WA A 34-year-old G6P3 with Hep C h/o IVDU and on Magnesium s/p Cesarean for PIH was taken back for an ex-lap for bleeding. She remained paralyzed post-operatively with only weak post-tetanic train-of-four elicited. The case exemplified differential diagnosis and management of post-operative paralysis in the post-partum pre-eclamptic patient and decision making points for her rapid sequence intubation. Saturday, October 12 1:00 PM - 2:30 PM OB MC173 Cesarean Delivery for a Parturient With Pulmonary Hypertension and Thrombocytopenia William Cederquist, M.D., Anna Dubovoy, M.D., Joanna Kountanis, M.D., University of Michigan Health System, Ann Arbor, MI A 31-year-old G6P3 woman at 28+5 weeks gestation was admitted with an insidious onset of dyspnea and found to have severe pulmonary hypertension (PA pressure 102/55 mmHg mean 75 mmHg PVR 16 WU). Her medical history was notable for cyanotic congenital heart disease repaired at age 3 but without long term followup. She was initiated on intravenous epoprostenol (prostacyclin) a potent pulmonary vasodilator and inhibitor of platelet aggregation but subsequently went into preterm labor at 32+3 weeks gestation. Here we describe the anesthetic management for Cesarean delivery in a patient with severe pulmonary hypertension. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM OB MC174 A Case of a Stuck Epidural Catheter in the Lateral Recess Stephanie Cheng, M.D., Thomas Halazynski, M.D., Yale University, New Haven, CT Epidural catheter was placed for a 20-year-old healthy actively laboring female which subsequently proved to be ineffective. Multiple attempts at removal with traction and positioning failed. Catheter stretch was noted. A second catheter for analgesia was placed the first one still in place. Following delivery repeated removal attempts were unsuccessful and Neurosurgery was consulted. A noncontrast CT scan showed catheter tip terminating in right L1-L2 lateral recess. With the patient in right lateral decubitus position flexion/extending of the waist arching of the pelvis left and right and saline injection the epidural catheter was removed with intact catheter tip. Saturday, October 12 1:00 PM - 2:30 PM OB MC175 Management of Massive Intraoperative Hemorrhage in Patients With Known Placenta Accreta: A Case Report Stephen Chin, D.O., Mari Baldwin, M.D., St Luke's Roosevelt Hospital Center, New York, NY We present a 37-year-old parturient with a known placenta accreta at 35 weeks gestation. Soon after a labor epidural was placed she presented to the operating room for caesarian section secondary to nonreassuring fetal tracing. Surgical delivery was complicated and hemodynamics were unstable due to considerable hemorrhage. General anesthesia was commenced and the infant was delivered successfully. Massive transfusion and resuscitation and hysterectomy took place. Surgical control of uterine artery bleeding was inadequate and required a trip to interventional radiology for uterine artery embolization. She was extubated on POD #1 and had no recall or neurologic or other sequelae. Saturday, October 12 1:00 PM - 2:30 PM OB MC176 A Unique Challenge: Obstetric Anesthesia for Harlequin Ichthyosis Andrea Choate, M.D., Thea Rosenbaum, M.D., UAMS, Little Rock, AR A 20-year-old with Harlequin Ichthyosispresented for the birth of her first child. She is one of only 12 people in the USA with this rare skin disorder and she is the first documented to give birth. Unique challenges in our anesthetic approach arose in the inability to tape the epidural catheter the tracheal tube and EKG and electrocautery pads to the skin. In addition possible upregulation of acetylcholine receptors and extreme hyperkalemia with succinylcholine use may be associated along with unknown anesthetic pharmacokinetics. Our choice of anesthesia was a success. Saturday, October 12 1:00 PM - 2:30 PM OB MC177 Epidural Anesthesia for Cesarean Section in an Achondroplastic Dwarf Isaac Chu, M.D., Jonathan Ko, M.D., Melissa Rocco, M.D., Mount Sinai, New York, NY An 18-year-old woman with achondroplasia presented for cesarean section for a full term intrauterine pregnancy. The patient had no prior surgeries. Her airway evaluation was characterized by a Mallampati I classification a large tongue and a depressed nasal bridge. On physical exam her spine was midline with no scoliosis. A neuraxial anesthetic was chosen because of airway concerns in achondroplasia and Copyright © 2013 American Society of Anesthesiologists pregnancy. An epidural provided increased control of the level of the neuraxial block and improved duration than a spinal anesthetic. The epidural was placed on the first attempt without complications and the surgery proceeded uneventfully. MC178 Saturday, October 12 1:00 PM - 2:30 PM OB MC178 Urgent Cesarean Section in a Morbidly Obese Patient With a Working Epidural Andrew Crabbe, M.D., Daniel BIggs, M.D., University of Oklahoma COM, Oklahoma City, OK A 36-year-old morbidly obese G4 P2 female presented in labor at 38 weeks. She has a BMI of 88 severe obstructive sleep apnea requiring oxygen and CPAP diabetes and hypertension. The patient had a working epidural but operative delivery was proposed because of failed progression. She was unable to lie supine thus a general anesthetic was indicated. An awake fiberoptic intubation was planned because of positioning and expected difficult intubation and was accomplished with topicalization of upper airway and ketamine sedation. Operative delivery was without event and the patient was electively ventilated until the following day then extubated. Saturday, October 12 1:00 PM - 2:30 PM OB MC179 Anesthesia Considerations of Loeys-Dietz Syndrome in Pregnancy: A Case Report Jessica Cronin, M.D., MBA, Harry Dietz, M.D., Xiaobo Dong, M.D., Ernest Graham, M.D., Jamie Murphy, M.D., Gretchen Oswald, M.S., Melissa Russo, M.D., Johns Hopkins Hospital, Baltimore, MD A 28-year-old primagravida woman with Loeys Dietz Syndrome (LDS) presented at 36 weeks gestation for scheduled primary elective cesarean delivery. The patient had clinical findings consistent with this diagnosis including mild aortic root dilation chronic right vertebral dissection with two cerebral aneurysms and small ectasias of the thecal sac in the lumbar region. Pregnant patients with LDS have significant risks including aneurysm rupture new aneurysm formation and uterine rupture. After a thorough preoperative evaluation the patient underwent a successful general anesthetic focused on maintenance of intraoperative hemodynamic stability and minimal intraoperative blood loss. Saturday, October 12 1:00 PM - 2:30 PM OB MC180 Twin Gestation With Placenta Percreta Matthew Culling, M.D., Eva Szabo, M.D., Eli Torgeson, M.D., University of New Mexico, Albuquerque, NM We present a 31-year-old G3 P2002 with a dichorionic diamnionic twin gestation with placenta accreta and placenta previa percreta invading the bladder wall. After a multidisciplinary conference she underwent cesarean section and hysterectomy at 28 weeks and 5 days. Her surgery was complicated by ureteral injury near total cystectomy and extensive blood loss. She had a general anesthesia with invasive monitoring. The massive transfusion protocol was initiated during the operation and she was taken to IR for emergent embolization of both internal iliac arteries. The intraoperative EBL was 15 liters. She was discharged on post-op day 28. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM OB MC181 Single Subarachnoid Blockade During Delivery of Second Baby in Twin Delivery Sabrina DaCosta, M.D., Ramsis Ghaly, M.D., Ned Nasr, M.D., John H. Stroger Jr. Hospital of Cook County, Chicago, IL 34-year-old G5P2112 female at 34 weeks gestation and BMI 35.5 presented with dichorionic-diamniotic twin gestation in cephalad/transverse lie. She was admitted with PPROM in pre-term labor. Patient was completely dilated and +1station. After relocation to the operating room for double set up patient delivered Twin A with several pushes. Twin B's frank breech presentation required urgent C/S. In right lateral position subarachnoid anesthesia was placed within two minutes. Evidence based recommendations for multi-gestation deliveries are lagging behind growing clinical demand. Subarachnoid blockade in lateral position can be performed safely for Twin B delivery when unanticipated C/S becomes necessary. Saturday, October 12 1:00 PM - 2:30 PM OB MC182 Remifentanil Induced Apnea: The Importance of Utilizing CPAP in the Known OSA Patient Jose De Leon, M.D., Tanya Lucas, M.D., Stephen Heard, M.D., University of Massachusetts Medical School, Worcester, MA A 31-year-old G2P3 with diabetes and BMI=40 presents for induction at 38 weeks for HELLP syndrome. An epidural was contraindicated due to platelets of 71K and falling. The patient consented to a remifentanil PCA for labor analgesia and the remifentanil was titrated from 25ucg to 50 ucg q 4 minutes. After 15 minutes at this dose the patient had a witnessed episode of apnea with the lowest spO2 in the mid-70s. Further investigation revealed the patient had a CPAP machine which was then used after remifentanil analgesia was resumed. Mother and baby had an uneventful hospital stay. Saturday, October 12 1:00 PM - 2:30 PM OB MC183 A Patient With Moya Moya Syndrome Presents for a Crash C-Section Due to Abruption Jose De Leon, M.D., Tanya Lucas, M.D., Laura Cohen, M.D., Bronwyn Cooper, M.D., Stephen Heard, M.D., University of Massachusetts Medical School, Worcester, MA A 35-year-old G5P0 presented for a high-risk consult at 32 weeks gestation. The following challenges were addressed: MoyaMoya Sydrome requiring long term Clopidogrel a history of extra- and intracranial anastomosis surgical treatment and deafness. At 36 weeks prior to having the Clopidogrel stopped the patient presented with abruption planceta and a FHR = 105 bpm with no variablity. An emergency c-section was called however no one on the team could communicate with the patient and the pre-natal records including the anesthesia consult could not be accessed. In minutes an anesthetic assessment and plan was delivered. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM OB MC184 Methadone Mom: Weighing the Risks of Methadone Maintenance in Baby and Mom Prianka Desai, M.D., Lori Oliver, M.D., Yale, New Haven, CT MR is a 26-year-old G1P1 with HCV and heroin abuse on methadone maintenance who presented with preterm labor at 24+6 weeks. Contractions subsided after treatment with steroids and magnesium. Her 250mg methadone dose was continued and EKG showed QTc interval of 526. The pain service was consulted. Her dose was increased during pregnancy from 225mg due to higher requirements. The management required input from obstetrics pain service and cardiology due to the risks. Literature searches on methadone tapering the assessment of QTc and the risks of withdrawal for mom and baby did not provide consistent guidelines for management. Saturday, October 12 1:00 PM - 2:30 PM OB MC185 Anesthetic Management of a Parturient With Prolonged QT Syndrome (LQTS) Sarah Deverman, M.D., Barbara Scavone, M.D., University of Chicago Medicine, Chicago, IL A 30-year-old patient 34 6/7 weeks gestation with LQTS presented for peripartum planning. Patient endorsed history of multiple syncopal events/cardiac arrest; is s/p BiV-ICD-pacer. Maternal b-blocker therapy is complicated by mild fetal bradycardia. Reports of parturients with LQTS remain scarce; risk increases peripartum (Drake-2007). With a multidisciplinary approach fundamental to management the anesthesiologist aims to decrease risk of dysrhythmias by moderating sympathetic activity secondary to anxiety labor pain laryngoscopy or surgical stimulation; preventing bradycardia/tachycardia; and avoiding QT-prolonging drugs (Behl-2005). Anesthetic plan included early neuraxial labor analgesia in a calm quiet setting possible cesarean under neuraxial anesthesia/general anesthesia in reserve. Saturday, October 12 1:00 PM - 2:30 PM CA MC186 Anesthetic Management of Living-Donor Renal Transplant Recipient With Prior Orthotopic Heart Transplant and Severe Pulmonary Hypertension Paul Anderson, M.D., Raed Abdullah, M.B. B.Ch., University of Pittsburgh Medical Center, Pittsburgh, PA Patients with pulmonary hypertension who undergo general anesthesia for non-cardiac surgery have increased risk of morbidity and mortality. We present a 51-year-old female with history of prior orthotopic heart transplant (for idiopathic cardiomyopathy) CAD with EF 40-45% (post-RCA stenting) and newly diagnosed pulmonary hypertension and elevated right heart pressures who underwent livingdonor renal transplant for end-stage renal disease secondary to tacrolimus toxicity. A pulmonary artery catheter was used to help guide management of the hemodynamics and pharmacological interventions especially during reperfusion of the graft. The patient had an uneventful intraoperative and postoperative course and went home on POD #4.

He suffered multiple fractures and a vascular injury requiring massive transfusion. He was emergently taken to the operating room for a left femoral to posterior tibial bypass and four-compartment fasciotomies. After 36 hours he was emergently taken back to the operating room for loss of Left lower extremity pulses. Sudden refractory hypotension followed by Ventricular fibrillation cardiac arrest was successfully resuscitated as per Advanced Cardiac Life Support protocol. Transesophageal echocardiography showed severely depressed right ventricular function suggesting a right ventricular contusion Saturday, October 12 1:00 PM - 2:30 PM CA MC188 Spinal Subdural Hematoma After Lumbar Drain Placement for FEVAR Camellia Asgarian, Robert Isaak, D.O., Harendra Arora, M.B. B.S., UNC Hospital, Durham, NC Spinal subdural hematoma after lumbar drain placement has not been reported for patients undergoing endovascular thoracoabdominal aortic aneurysm (TAAA) repairs. We describe the case of a 71-year-old male who developed a symptomatic spinal subdural hematoma after placement of a lumbar drain for endovascular TAAA repair. The patient developed weakness in his lower extremities 12 hours postoperatively. MRI showed a spinal subdural hematoma from T12/L3 with cord compression. The patient did not received surgical decompression but rather replacement of the lumbar drain by the neurosurgical team. The patient was discharged on POD #9 with 4+/5 strength in both lower extremities. Saturday, October 12 1:00 PM - 2:30 PM CA MC189 Epidural Hematoma After Removal of Lumbar Drain for Thoraco-Abdominal Aortic Aneurysm Surgery Camellia Asgarian, M.D., UNC Hospital, Durham, NC Epidural hematoma is an uncommon complication after lumbar drain placement for thoracoabdominal aortic aneurysm (TAAA) repair. We describe the case of an 86-year-old man who underwent an endovascular TAAA repair with lumbar drain placement. The patient's intraoperative and post-operative course was uneventful. The lumbar drain was removed and he was discharged on POD 2. On POD 3 the patient returned with bilateral lower extremity weakness. MRI revealed an epidural hematoma with cord compression. He underwent emergent laminectomy for hematoma evacuation. At the time of discharge his only remaining deficit was 4/5 strength in his left hamstring.

B.S., Georgia Regents University of Augusta, Augusta, GA A 59-year-old Jehovah's Witness male with severe sepsis secondary to necrotizing fasciitis of left upper extremity was diagnosed with NSTEMI and transferred to our institution for emergency CABG surgery. The procedure was uneventful and the Hb level on arrival to the ICU was 6.8 g/dl. During the immediate postoperative period the patient had significant blood loss requiring factor VII desmopressin and emergency surgical re-exploration. The postoperative recovery was uncomplicated in spite of Hb level of 3.3 g/dl. He was continued on erythropoietin and extubated on day ten and discharged home on day thirty after resolution of the necrotizing fasciitis. Saturday, October 12 1:00 PM - 2:30 PM CA MC191 A Successful Case of Sequential Lung Isolation Using the EZ-Blocker in a Morbidly Obese Patient With Dilated Cardiomyopathy Who Presented for Bilateral Video-Assisted Thoracoscopic Maze for Atrial Fibrillation Emily Ashford, M.D., Mary Arthur, M.D., Georgia Regents University of Augusta, Augusta, GA 43-year-old morbidly obese male presented for a bilateral Video-Assisted Thoracoscopic Maze for chronic atrial fibrillation. His past medical history included dilated cardiomyopathy requiring a biventricular ICD. His LV function was globally depressed (EF 20%). After induction of anesthesia the Yshaped EZ-blocker which has two cuffs on the bifurcated distal ends was advanced under fiber-optic guidance into the right and left main bronchus respectively. Sequential lung isolation was achieved by inflating the cuff of the corresponding main bronchus. Surgical exposure was good with no episodes of hypoxemia or cuff dislodgement. The patient was extubated after the procedure with no complications. Saturday, October 12 1:00 PM - 2:30 PM CA MC192 Therapeutic Hypothermia After Witnessed Cardiac Arrest Requiring Advanced CPR and Urgent CABG Surgery Emily Ashford, M.D., Manuel Castresana, M.D., Sanjay Dwarakanath, M.B. B.S., Vikas Kumar, M.B. B.S., Georgia Regents University of Augusta, Augusta, GA 58-year-old male with past medical history of hypertension and diabetes presented to our ICU after witnessed ventricular fibrillation arrest at his work place with successful return of spontaneous circulation after 12 minutes of cardio-pulmonary resuscitation. On admission cardiac catheterization showed multi-vessel coronary disease with EF of 30%. He was placed on intra-aortic balloon pump and therapeutic hypothermia protocol. The next day he underwent successful coronary artery bypass graft in spite of peri-operative complications included metabolic acidosis hyperglycemia and coagulopathy. Post-operatively inotropic vasopressor IABP and ventilatory supports were successfully weaned extubated on day 10 and later discharged home without neurologic deficit.

PSH: CABG 2003 and AICD 1994. Following induction radial arterial line and femoral venous introducer were placed. TEE: dilated RA with 3.5 cm vegetation and 2+ TR. After ICD lead extraction acute etCO2 decrease was observed and severe hypotension ensued. ABG: increased pCO2-etCO2 gradient and acute decrease in pO2 of 456-157. TEE: RV overload and LV distension. No vegetation seen. Deterioration continued in spite of norepinephrine and epinephrine. ACLS was initiated. After 32 mins CPR TEE confirmed thrombosis in all four chambers but embolism was seen in PA. Resuscitation efforts aborted. Saturday, October 12 1:00 PM - 2:30 PM CA MC194 Successful Emergency Surgical and Anesthetic Management of a Right Ventricular Perforation From Laser Lead Extraction Mark Banks, M.D., Mary Arthur, M.D., Vinayak Kamath, M.B. B.S., Brent Shafer, P.A., Georgia Regents University, Augusta, GA Laser lead extractions can result in fatal cardiovascular injuries despite surgical intervention. We report a successful case of a repair of a right ventricular (RV) and left innominate vein perforation following laser lead extraction of a malfunctioning RV lead in an 82-year-old female with a history of non-ischemic cardiomyopathy. A sudden hypotensive episode followed by cardiac standstill confirmed by fluoroscopy and TEE prompted the initiation of ACLS and an emergent median sternotomy with repair on cardiopulmonary bypass (CPB). The patient was successfully weaned from CPB requiring inotropic support ICU care and extubated on postoperative day 5 neurologically intact. Saturday, October 12 1:00 PM - 2:30 PM CA MC195 Asymptomatic Cold Agglutinins Discovered the Day of Cardiac Surgery Emily Sharpe, M.D., David Barbara, M.D., David Cook, M.D., Mayo Clinic College of Medicine, Rochester, MN A 49-year-old male with a history of Hodgkin's lymphoma treated with radiation therapy presented for CABG and pericardiectomy. Blood bank antibody screening revealed a cold autoantibody. He denied associated anemia or peripheral agglutination. Active warming techniques were utilized intraoperatively. Normothermia (37C) was maintained on cardiopulmonary bypass and tepid (34C) blood cardioplegia administered. The patient experienced no perioperative complications. Cold agglutinins are autoantibodies that may result in red blood cell agglutination on exposure to cold. In asymptomatic patients cardiac surgery can be safely performed without additional testing using normothermic cardiopulmonary bypass and avoidance of cold cardioplegia.

B.S., Feroze Mahmood, M.D., Robina Matyal, M.D., Beth Israel Deaconess Medical Center, Boston, MA, Mario Gallegos, M.D., University of Costa Rica, San Ramon, Costa Rica Luyang Jiang, M.D., Peking University People's Hospital, Beijing, China A 24-year-old intravenous drug user presented with word-finding difficulties secondary to a stroke. Transthoracic echo demonstrated large mitral valve vegetation with severe mitral regurgitation necessitating mitral valve replacement. Intraoperative transesophageal echo demonstrated a septum within the left atrium with all pulmonary vein openings on one side of the septum and the atrial appendage on the other side. Resection of left atrial appendage and the septum in addition mitral valve replacement was performed.Resolution of mitral regurgitation was confirmed by post procedure TEE. Saturday, October 12 1:00 PM - 2:30 PM CA MC197 Undiagnosed Pheochromocytoma During ECMO Decannulation Amy Beethe, Amy Duhachek-Stapelman, M.D., University of Nebraska Medical Center, Omaha, NE Peri-operative care of a patient with pheochromocytoma presents multiple challenges and if undiagnosed is associated with intraoperative mortality of approximately 80%. A 46-year-old female who presented with chest pain had rapid deterioration of her cardiac ejection fraction to 5% after cardiac catheterization requiring emergent ECMO placement. The diagnosis was presumed viral myocarditis. Following myocardial recovery anesthesiology was consulted for ECMO decannulation. Intraoperatively three episodes of profound medically resistant hypertension occurred (increased MAP from 65 to 140mmHg). After consideration of an ultrasound revealing a hemorrhagic adrenal mass she was treated empirically for pheochromocytoma with phentolamine which resulted in cardiovascular stability. Saturday, October 12 1:00 PM - 2:30 PM CA MC198 Left Atrial Dissection Secondary to Coronary Sinus Cannulation: Evaluation Evolution and Treatment John Berry, M.D., Nishita Dalal, M.D., Pryia Kumar, M.D., Susie Martinelli, M.D., William Stansfield, M.D., UNC Hospitals, Chapel Hill, NC A 74-year-old male underwent coronary artery bypass grafting aortic valve replacement and thoracic aortic arch repair. During the course of the operation the appearance of an unusual LA mass on transesophageal echocardiography examination prompted a search for its cause. It was determined to be a LA dissection a rare complication linked with specific cardiac surgeries. The natural progression of this unusual pathology was followed with sequential TEE studies over the course of multiple operations. We present a case report and literature review focusing on the echocardiographic features for identification progression and management of this rare complication. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM CA MC199 Investigating Pacemaker Dysfunction in the Operating Room Meghan Bhave, M.D., Victor Pascua, University of California San Francisco, San Francisco, CA We present a pacemaker-dependent patient undergoing neck dissection. Intraoperatively magnet placement rendered the device asynchronous. External pacing pads were applied as a further precaution and the case proceeded uneventfully. Prior to extubation arterial line and plethysmography monitoring showed no evidence of circulation following magnet removal. Thus the magnet was re-applied to restore perfusion. We later determined that the external pacer was inadvertently functioning but charged to a current level insufficient to capture the ventricle. Once this source of interference was off the pacemaker reverted back to DDD mode after magnet removal and the patient was successfully extubated. Saturday, October 12 1:00 PM - 2:30 PM CA MC200 Coronary Vasospasm With Anomalous Origin of Left Main Jason Blitz, M.D., Polyana Silver, M.D., Walter Reed National Military Medical Center, Bethesda, MD Forty-five-year-old male with history of obesity OSA HTN and tobacco use presented for colon resection due to adenocarcinoma. Preoperative TTE stress test and ECG were unremarkable. After anesthesia induction three episodes (1-5min) of significant ST elevations occurred resolving spontaneously without hypotension tachycardia or ectopy. Intraoperative TEE EKG and postoperative cardiac troponins were negative. Coronary artery catheterization revealed anomalous origin of the left main from the right coronary sinus. Although cardiology concluded that ST changes were due to vasospasm and the anomalous anatomy was an incidental finding literature suggests that aberrant coronary artery anatomy can be directly associated with vasospasm. Saturday, October 12 1:00 PM - 2:30 PM CA MC201 Cardiac Tamponade During Attempted Percutaneous Peri-Valvular Leak Closure After Transcatheter Aortic Valve Implantation (TAVI): Immediate Cardiac Surgical Intervention in the Hybrid Cath Lab Patrick Britell, M.D., Lebron Cooper, M.D., University of Miami, Maimi, FL Anterograde percutaneous closure of aortic peri-valvular leak via femoral vein POD2 after TAVI. Immediately following atrial septotomy tamponade ensued with hemodynamic instability. After emergent pericardiocentesis 7L blood were drained under constant aspiration. Upon surgeon arrival patient was too unstable to transport to OR. After sternotomy perforation of dome of LA was identified and ligated and AVR was performed on CPB in hybrid cath lab. Weaning from CPB required epinephrine and IABP. Following successful surgical intervention in the cath lab the patient was discharged home on POD19. Surgical intervention in the cath lab may be safer than OR in certain situations.

On admission day 1 the EKG showed prolonged QTc intervals. On hospital day 4 she developed a V-fib cardiac arrest. EKG after ROSC revealed a QTc of 850 milliseconds. The progression of QTc duration during her hospital course was recorded. Several medications and comorbidities contributed to torsade de pointes. All culprit medications were discontinued and electrolytes were replaced. Isoproterenol infusion and intravenous phenytoin therapy were used to shorten the QTc which normalized in 2 days. Saturday, October 12 1:00 PM - 2:30 PM CA MC203 Postoperative Very Late Drug Eluting Stent Thrombosis in a Jehovah's Witness After Plavix Withdrawal Enrico Camporesi, M.D., Devanand Mangar, M.D., Collin Sprenker, B.S., J. Thompson Sullebarger, M.D., Florida Gulf-to-Bay Anesthesiology Associates LLC, Tampa, FL, Hesham Omar, M.D., Mercy Hospital, Chicago, IL A 54-year-old Jehovah's Witness gentleman was scheduled for bilateral knee replacement. He had a history of 3 coronary stent for recurrent anginal pains (1 BMS and 2 DES all deployed >40 months). Last angiogram showed no occlusive disease. Plavix was stopped 5-days earlier. Postoperatively while in the PACU he suffered lateral STEMI and a V-fib arrest. Angiography showed thrombosis of 2 DES with sparing of BMS. AngioJet thrombectomy successfully debulked the thrombus in the LCX and LAD. This acute thrombosis of DES -but not BMS- exemplify how DES are more prone to this compliacation due to delayed endothelialization. Saturday, October 12 1:00 PM - 2:30 PM CA MC204 A Potentially Devastating Case of Perioperative Vision Loss After Coronary Artery Bypass Grafting Sneha Chandra, M.D., Hesham Omar, M.D., MetroHealth Medical Center, Cleveland, OH A 49-year-old male with hypertension hyperlipidemia asthma and sleep apnea was scheduled for CABG. His past medical history was significant for a gunshot wound to the head with subsequent seizures and mild dementia. There was mild bilateral carotid artery disease. ECG showed sinus rhythm and anterior wall STEMI. LV ejection fraction was 45%. After uneventful CABG with cardiopulmonary bypass the patient's left pupil was dilated at 8 mm and non-reactive to light while his right pupil measured 2 mm and was reactive. There was worsening of cognition. Eventually the patient became increasingly oriented and vision returned to baseline.

Patient found to have mass occupying entire right atrium and crossing tricuspid valve resulting in significant hypoxia and left ventricular dysfunction. Patient was taken emergently to the OR requiring pressors prior to induction and intraoperatively. Following excision of 8x9 cm myxoma patient developed severe tricuspid regurgitation. We will discuss anesthetic implications of Carney's Complex a rare disorder with predisposition for recurrent atrial myxomas. We will also review intraoperative echocardiography of obstructing lesions management of right ventricular outflow obstruction and postoperative sequelae following excision. Saturday, October 12 1:00 PM - 2:30 PM CC MC206 Suspected Heparin-Induced Thrombocytopenia and Thrombosis Syndrome (HITTS) With Mesenteric Thrombosis in a Living Liver Donor Patient Catherine Cooper, M.D., Virginia Commonwealth University Medical Center, Richmond, VA A 38-year-old liver donor had significant acidosis and rising creatinine at the end of partial hepatectomy. The following day ultrasound showed low portal vein flow. At reopearation extensive clot was found in the mesenteric veins and there was evidence of coagulopathy without bleeding. A diagnosis of HITTS was made and treated with bivalirudin. Saturday, October 12 1:00 PM - 2:30 PM CC MC207 Case Report: Long-term Pentobarbital Coma in Treatment of Posterior Reversible Encephalopathy Syndrome Post Liver Transplant Elviira Corsi, D.O., Dimitri Bezinover, M.D., Patrick McQuillan, M.D., Subramanian Sathishkumar, M.B. B.S., Sonia Vaida, M.D., Penn State Milton S. Hershey Medical Center, Hershey, PA We are presenting a case of 26-year-old female with posterior reversible encephalopathy syndrome after liver transplantation. She received a deseased donor liver transplant due to fulminant liver failure secondary to amatoxin mushroom poisoning. The patient developed PRES with symptoms of severe brain edema and did not improve despite of adjustment of immunosupressive therapy. She required maximal therapy including cooling mannitol 3% saline and pentobarbital infusion. All attempts to reduce the dose of pentobarbital failed due to intractable seizure activity. Only after 62 days the therapy was successfully tapered. The patient was discharged to rehabilitation center without neurologic deficits.

He underwent upper doubleballoon enteroscopy and ERCP under general anesthesia. Following the DBE an air cholangiogram was obtained. Soon thereafter a drop in end tidal CO2 bradycardia and hypotension ensued. After transient response to vasoactive medications PEA arrest occurred. ACLS was initiated. Arterial line and central line were placed. TEE confirmed air in both sides of the heart indicative of venous air and paradoxical air emboli. Despite aspiration of air from central line resuscitation was unsuccessful. Saturday, October 12 1:00 PM - 2:30 PM CC MC209 Subanesthetic Ketamine Infusion to Manage Anxiety in a Chronically Critically Ill Patient Daniela Darrah, M.D., Vivek Moitra, M.D., Columbia University College of Physicians and Surgeons, New York, NY A 55-year-old required ECMO for ARDS. After developing intra-abdominal hemorrhage and sepsis he became chronically critically ill and complained of severe anxiety. His symptoms were assessed with the Hospital Anxiety and Depression Scale (HADS). At baseline his score was maximal for anxiety and consistent with depression. An infusion of ketamine (3 mcg/kg/min) was administered for 72 hours and the HADS was repeated daily. After 24 hours his score demonstrated a 27% improvement in symptoms; 21% improvement was retained one day after the infusion was completed. He denied any unpleasant psychotomimetic symptoms. Saturday, October 12 1:00 PM - 2:30 PM CC MC210 Early Extubation in an O2 Dependent Patient Following High Risk Surgery With Multiple Blood Transfusions Kunal Desai, M.D., Sharline Kashfian-Halimi, M.D., Marianna Mogos, M.D., Pete Roffey, M.D., Duraiyah Thangathurai, M.D., LAC+USC Medical Center, Los Angeles, CA An 82-year-old male with PMH of severe COPD on 2L O2 at home moderate aortic stenosis CKD stage V and anemia with bladder cancer presents for radical cystectomy. The procedure was 6.5 hours and the patient received 5 units PRBCs. The patient was brought to the ICU as due to comorbid conditions involving his respiratory cardiac renal and hematologic systems. Within an hour of arriving to the ICU the decision was made to extubate the patient based on clinical status and risk benefit analysis regarding documented higher incidence of extubation failure in patients with prolonged mechanical ventilation. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 1:00 PM - 2:30 PM CC MC211 Use of Bedside Ultrasound in the Management of Unexplained Acute Hypoxemia in a Mechanically Ventilated Patient With Acute Inflammatory Demyelinating Polyneuropathy Rasesh Desai, M.D., Avinash Kumar, M.D., Vanderbilt University, Nashville, TN 64-year-old male with acute inflammatory demyelinating polyneuropathy complicated by quadriparesis respiratory failure and autonomic instability became acutely hypoxemic. Hypoxemia did not resolve despite increase in PEEP and FIO2. Throughout this episode ventilation dynamic compliance and peak pressures remained unchanged. Chest X-ray showed low lung volumes with patchy infiltrates. Bedside thoracic ultrasonography showed no pneumothorax pulmonary edema or pericardial effusion but revealed significant new right lower lobe consolidation not clearly evident on chest x-ray. Patient was rolled to contralateral side with resolution of hypoxemia consistent with shunt physiology. Patient continues to improve from his likely aspiration pneumonia. Saturday, October 12 1:00 PM - 2:30 PM CC MC213 Heparin Induced Thrombocytopenia Complicated by Cardiac Ischemia Hemothorax and High Dose Argatroban Daltry Dott, M.D., Joseph Schlesinger, M.D., Vanderbilt University Medical Center, Nashville, TN 57-year-old male status post coronary artery bypass surgery who developed chest pain secondary to ischemia pericarditis and presumptive microvascular thrombi from heparin-induced thrombocytopenia who required high-dose argatroban to obtain a therapeutic aPTT. Chest pain was attributed to pericarditis and acute graft thrombosis as demonstrated on EKG and echocardiogram. During dualanticoagulation therapy he developed an expanding left-sided hemothorax that required drainage with a pigtail catheter placement. This case presents a diagnostic challenge of multifactorial chest pain juxtaposed with management of anticoagulation while undergoing procedural intervention and weaning high dose argatroban to warfarin monotherapy and ensuring therapeutic anticoagulation. Saturday, October 12 1:00 PM - 2:30 PM CC MC214 Unusual Placement of Left Subclavian Central Venous Catheter After Emergency Craniotomy Bradley Drury, M.D., Kayiguvwe Kragha, M.D., Solomon Levy, M.D., Detlef Obal, M.D., Ph.D., Matthew Stephens, M.D., University of Louisville, Louisville, KY An 83-year-old white female became hemodynamically unstable after developing a combined subdural/epidural hematoma subsequent to a fall from standing height. After taking the patient to the operating room for emergency craniotomy the left subclavian central venous catheter (CVC) placed during surgical preparation exhibited a central venous pressure tracing that suggested an intrathoracic position of the catheter. Interestingly on the postoperative conformational chest x-ray the tip of the CVC appeared in the left hemithorax. Possible explanations and rare anatomic variations leading to this unforeseen finding will be discussed in this case presentation.

Stephen Estime, Michael Woo, M.D., University of Chicago, Chicago, IL An 84-year-old male with a past medical history significant for an ischemic cardiomyopathy s/p Heartmate II implantation presented to the hospital with signs of LVAD thrombosis. Due to advanced age compounded by multiple medical problems the patient was not deemed a candidate for emergent VAD replacement. The patient was taken to the interventional cardiology suite for catheter directed TPA administered thrombolysis. Several hours into treatment the patient developed mental status changes and was subsequently found to have a large intraparenchymal hemorrhage. Saturday, October 12 1:00 PM - 2:30 PM CC MC216 Altered Mental Status Left Hemiparesis Right Gaze Preference: What's the Diagnosis? Shahbaz Farnad, M.D., Sandra Goyal, M.D., Arvind Rajagopal, M.D., Rush University Medical Center, Chicago, IL Altered mental status hemiparesis and visual gaze preference often cue physicians to a diagnosis of stroke or other neurologic pathology. Acute aortic dissection rarely presents only with neurologic symptoms. The potentially fatal nature of aortic dissection necessitates rapid recognition and treatment and should be considered when faced with a presentation of stroke-like symptoms. We present a case of a 66-year-old female on anti-coagulation therapy with a history of atrial fibrillation and CAD who presented with stroke-like symptoms and negative CT findings for hemorrhagic stroke. She was found to have acute Type A aortic dissection requiring open repair. MCC Session Number – MCC04 Saturday, October 12 3:00 PM - 4:30 PM CC MC217 Case Report: Successful Use of Extracorporeal Membrane Oxygenation in a Patient With Toxic-Shock Induced Cardiogenic Shock Eilon Gabel, M.D., Vadim Gudzenko, M.D., UCLA, Los Angeles, CA We present a case of toxic-shock induced cardiomyopathy in a patient brought to UCLA after being found unarousable on an airplane. Upon presentation the patient was hypotensive with a Left Ventricular Ejection Fraction (LVEF) of 5-10% leukocytosis and bandemia. The patient became increasingly unstable requiring vasopressors antibiotics intravenous immunoglobulin antiarrhythmics and ultimately veno-arterial ECMO. Seven days later the patient's LVEF improved to 35-40% and ECMO was successfully discontinued. By the next day vasopressors were stopped and the patient was extubated. Blood cultures remained negative and toxic-shock was diagnosed by exclusion after staphylococcus aureus was identified in chronic lower extremity wounds.

She was started on antibiotics but was not a surgical candidate and the palliative care service was consulted for a presumed life expectancy of less than 24 hours. However the patient lived over a week longer much of that time visiting with friends and family. Her nausea and pain were well-controlled by the palliative care team. Saturday, October 12 3:00 PM - 4:30 PM CC MC219 Severe Hypoxia Due to Broncho-Esophageal Fistula and Acute Lung Injury Treated With Differential Lung Ventilation Mark Giska, M.D., Beaumont Health System, Royal Oak, MI An elderly male in the Surgical Intensive Care Unit following esophagectomy developed worsening hypoxia due to broncho-esophageal fistula and acute lung injury. An attempt at operative repair was aborted because of failure to adequately oxygenate during one lung ventilation. He developed pulseless electrical activity upon return to the SICU and was successfully resuscitated. Multiple ventilator modalities were then employed during differential lung ventilation but ultimately proved to be unsuccessful. Respecting his wishes for no heroic measures his family decided to withdraw care and the patient expired later that day. Saturday, October 12 3:00 PM - 4:30 PM CC MC220 Is the Central Line on the Left Side of the Heart? Patient With Klippel Trenaunay Weber Syndrome and Unknown Persistent Left Superior Vena Cava Andrea Gomez Morad, M.D., Natalie Bruno, M.D., Saint Elizabeth's Medical Center, Boston, MA, Jeffrey Kane, M.D., Lahey Clinic, Boston, MA Klippel-Trenaunay-Weber syndrome is associated with vascular malformations. Persistent left superior vena cava (PLSVC) is a rare condition but a common congenital anomaly of the thoracic circulation. We present a case of a 42 -year-old Male with Klippel-Trenaunay-Weber syndrome and unidentified PLSVC admitted to SICU after emergency craniotomy. A left internal jugular vein catheter was placed under ultrasound guidance Follow up chest X-ray showed a catheter localized in the left hemithorax following a paramediastinal course. Catheter was removed and right sided subclavian catheter was placed. Later the presence of a PLSVC was confirmed by a previous CT thorax.

Ravindra Gupta, M.D., Geraldine Diaz, D.O., Sacha Pollard, Pharm.D, Sarah Sokol, Pharm.D, University of Chicago, Chicago, IL A 65-year-old morbidly obese female with diabetes, hypertension, chronic pancreatitis, and cigarette smoking underwent a ventral hernia repair. Postoperatively the patient required intubation for respiratory distress. A chest CT demonstrated a right upper lobe PE and anticoagulation with intravenous heparin utilizing aPTT monitoring was initiated. While demonstrating therapeutic aPTT levels the patient received a CT scan for repeated failure to extubate that demonstrated a new PE of the left lower lobe. In response heparin monitoring utilizing anti-Factor Xa levels was implemented. After 24 hours of therapeutic anti-factor Xa levels (0.3-0.7Units/mL) the patient was extubated with aPTT > 200 seconds. Saturday, October 12 3:00 PM - 4:30 PM CC MC223 The Use of Extracorporeal Membrane Oxygenation in Autoimmune Acute Respiratory Distress Syndrome Jacob Gutsche, M.D., John Augoustides, M.D., University of Pennsylvania, Philadelphia, PA 39-year-old female transferred from an outside hospital with a diagnosis of fulminant ARDS secondary to pneumonia. The patient experienced a brief cardiac arrest at the outside hospital before intubation. Due to difficulties in oxygenating the patient we placed the patient on veno-venous ECMO which facilitated low stretch mechanical ventilation. The patient's cultures were negative for bacterial or viral pneumonia. The workup was expanded to include autoimmune disease etiologies and a diagnosis of acute systemic lupus erythematosus mediated pneumonitis. The patient was started on high dose intravenous steroids and improved rapidly. Saturday, October 12 3:00 PM - 4:30 PM CC MC224 Diabetes Insipidus - A Rare Side Effect of Olanzaprine Aysha Hasan, Shaul Cohen, M.D., Adil Mohiuddin, M.D., Diane Ridley, M.D., Sahebjit Bhasin, Student, Christine Hunter, M.D., UMDNJ-Robert Wood Johnson University Hospital, Belle Mead, NJ 77-year-old female (150 cm 72 kg) with HTN DVT diverticulitis and LE weakness presented to ER with severe abdominal pain. A Hartman's procedure was performed and transferred to ICU. She developed delirium and treated with Olanzapine. The patient's urine output >5 liters/day. Common etiologies were explored. Finally after discontinuing olanzapine within 24 hours the patient improved. Central DI is caused by decreased secretion of ADH. Common laboratory findings include urine osmolality <300 and urine output >50 ml/kg/day. Nephrogenic DI is inability of ADH to bind renal receptors. Many drugs and medical conditions can cause DI. Management includes discontinuation of drug.

He was intubated on arrival. He had left facial fractures left intracerebral hemorrhage and injury to the external carotid artery. He became hypotensive and bradycardic in the ER and was resuscitated with blood products and vasopressors. On arrival of family he was identified as a Jehovah's Witness. Blood conservation measures were employed. He failed a trial of extubation on hospital day 2 and was made DNR/DNI by relatives. He passed away in a few hours. Saturday, October 12 3:00 PM - 4:30 PM CC MC226 Usefulness of Novel Multimodal Monitoring During Controlled Hypotension in a Jehovah's Witness Undergoing Radical Nephrectomy and Liver Resection Chad Heng, Susan Darrah, Mariana Mogos, Peter Roffey, Duraiyah Thangathurai, Los Angeles County+Univerity of Southern California Medical Center, Los Angeles, CA A 47-year-old Jehovah's Witness with renal cell carcinoma and direct invasion of the liver underwent right radical nephrectomy. To minimize blood loss controlled hypotension was utilized. In the past this technique has been used without adequate monitoring leading to increased risk of ischemia. A novel multimodal monitoring strategy including cerebral oximetry TEE venous blood gas and urine output was implemented to ensure safety and maintain vital organ perfusion. Adequate cerebral myocardial and renal perfusions were demonstrated even at the lowest levels of hypotension. Blood loss was minimal and the patient was discharged from ICU on POD #1. Saturday, October 12 3:00 PM - 4:30 PM CC MC227 Vasospasm in a Patient With Sickle Cell Disease Daniel Hernandez-Barajas, M.D., Peggy White, M.D., University of Florida, Gainesville, FL 25-year-old AAM with history of SCD diagnosed subarachnoid hemorrhage. On arrival no neurologic deficits were noted. Shortly after he had decline in his neurologic status and EVD was placed. Hematology recommended partial manual exchange transfusion with a goal of HbS of 30% or less achieved with 8 UPRBC. Days later he underwent a coil embolization of a ruptured left posterior communicating aneurysm. Patient underwent transcranial doppler to assess for vasospasm afterwards he was diagnosed with symptomatic vasospasm with AMS responsive to systolic blood pressures >160 vasopressors were started. He also underwent angiogram with intraarterial verapamil.

Post operative day one the patient with no known thyroid disease or cardiac history except for pericarditis twelve year prior was noted to be in new onset atrial fibrillation. Metabolic and radiologic workup revealed hyperthyroidism without classic symptoms of hyperthyroidism and a multinodular goiter. The patient was treated with Tapazole and made complete recovery. This case serves to raise awareness of the risks of morbidity from uncommon presentations after common diagnostic tests. Saturday, October 12 3:00 PM - 4:30 PM CC MC229 Too Much of a Good Thing? The Role of Immunosuppression in Graft Versus Host Disease After Liver Transplant Jessica Hobbs, M.D., Christopher Franklin, M.D., Caron Hong, M.D., University of Maryland, Baltimore, MD Graft-versus-host disease (GVHD) after liver transplant is rare with an incidence of 0.1%. Our patient was a 65-year-old male with end-stage liver disease secondary to hepatitis C who underwent liver transplant without complication. Approximately 3 weeks later the patient experienced fever pancytopenia and rash which after biopsy were found to be secondary to GVHD. Immunosuppression was increased but the patient expired 3 months after transplant. Recent studies have shown while increasing immunosuppressive medications is the current recommendation for GVHD it may be more efficacious to decrease immunosuppression in order to allow the host's immune system to attack donor T-cells. Saturday, October 12 3:00 PM - 4:30 PM CC MC230 A New Discovery that May Not be So New: Anti-N-Methyl-D-Aspartate Receptor Encephalitis Jessica Hobbs, M.D., Christopher Franklin, M.D., University of Maryland, Baltimore, MD Anti-N-methyl-D-asparate receptor (NMDAR) encephalitis is a neurological disorder associated with antibodies against the NMDA receptor. Patients suffering from NMDAR encephalitis present with psychosis memory deficits seizures and language degeneration. It can progress to a catatonic state associated with abnormal movements and autonomic and breathing instability. It is often associated with a tumor and if a tumor is present patients respond faster to immunotherapy after resection than do patients without a tumor. We describe a 33-year-old female with HIV infection who presented with seizure activity that progressed to encephalopathy requiring intubation. The patient was subsequently found to have anti-NMDAR encephalitis. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM CC MC231 Postoperative Management of Severe Fixed Pulmonary Hypertension and Cardiac Dysfunction After Complex Multi-Valvular Cardiac Surgery Tiffany Richburg, M.D., Abigail Hoffman, M.D., John Beatty, M.D., Manuel Castresana, M.D., Shvetank Agarwal, M.D., Georgia Regents University, Augusta, GA A 57-year-old woman with severe rheumatic mitral aortic and tricuspid valve disease with resultant group II pulmonary hypertension underwent mechanical mitral and aortic valve replacements as well as tricuspid annuloplasty. Postoperatively she developed complete right ventricular failure secondary to severe pulmonary hypertension that was unresponsive to multiple inotropes intra-aortic balloon pump and pulmonary vasodilators including nitric oxide inhaled prostacyclin and sildenafil. Simultaneously the patient developed severe pulmonary dysfunction requiring increasing PEEP and oxygen requirements. This case highlights the challenges in management of patients with severe fixed group II pulmonary hypertension after complex cardiac surgery. Saturday, October 12 3:00 PM - 4:30 PM CC MC232 Anesthetic Considerations for Ex-Vivo Liver Surgery Ryan Ivie, M.D., Tricia Brentjens, M.D., Columbia University, New York, NY Ex-vivo liver surgery involves the resection of the liver and potentially neighboring abdominal organs en bloc resection of the embedded tumor and reimplantation of the organ(s). It is indicated for patients with liver cancer who have failed alternative treatments and offers the advantage of bloodless dissection and reconstruction. We describe a series of cases that exemplify the anesthetic management of ex-vivo liver surgery. Unique characteristics include prolonged anhepatic phase large area of cut hepatic surface resulting in rapid and difficult to control hemorrhage on reperfusion and massive transfusion over an unusually brief period of time requiring advance preparation. Saturday, October 12 3:00 PM - 4:30 PM CC MC233 Airway Management for Tracheal Disruption: Emergency Department to the Intensive Care Unit Julie Joseph, M.D., Jefferey Berman, M.D., UNC, Chapel Hill, NC Tracheal injury following non-penetrating trauma is rare but life threatening. It requires immediate intervention. A 31-year-old 105 kg ASA 1 male dropped a 200-pound barbell on his neck while bench pressing. He presented in moderate distress. Anesthesia was called to the emergency department to intubate. Physical exam demonstrated crepitus in his neck and supraclavicular areas. The trachea moved with respirations. He was taken emergently to the operating room. Surgical exploration revealed tracheal disruption with only the membranous trachea intact. The trachea was repaired and a tracheostomy placed above the injury. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM CC MC234 Rhabdomyolysis After Prolonged Foot Surgery Arun Kalava, Samuel Leung, M.D., Joel Yarmush, M.D., New York Methodist Hospital, Brooklyn, NY, Monica Midha, M.D., Jersey Shore University Medical Center, Neptune, NJ Rhabdomyolysis occurs extremely rarely intra-operatively and post-operatively. Undiagnosed and untreated rhabdomyolysis may lead to complications the most serious of which are acute renal failure and death. Prolonged surgical time and immobilization are known risk factors that contribute to rhabdomyolysis. To our knowledge rhabdomyolysis has not been reported following foot surgery. We present a patient with Charcot deformity who underwent corrective surgery that was 9 hours in duration. Intra-operatively the patient developed hyperkalemia acidosis and hypotension and was subsequently diagnosed with rhabdomyolysis. Additionally muscle damage was not distal to or at the site of tourniquet application as reported in many cases. Saturday, October 12 3:00 PM - 4:30 PM CC MC235 Anesthetic Management of a Patient With Lethal Catatonia Undergoing Emergent ECT Siri Kanmanthreddy, M.D., Steve Barnes, M.D., Rush University Medical Center, Chicago, IL A 47-year-old female with history of hypertension diabetes bipolar disorder and neuroleptic malignant syndrome was transferred to our facility after failed medical management of lethal catatonia at an outside hospital. She presented with fever tachycardia hypertension altered mentation and rigidity requiring emergent ECT. General anesthesia was induced with methohexital and rocuronium a laryngeal mask airway (LMA) placed and mechanical ventilation delivered. Upon ECT completion neuromuscular blockade was reversed and the LMA removed. She underwent eight more ECTs utilizing comparable anesthetic agents but varying airway management techniques. At their conclusion her vital signs stabilized rigidity resolved and mental status improved. Saturday, October 12 3:00 PM - 4:30 PM CC MC236 Emphysematous Esophago-Gastritis Associated With Hepatic-Portal Venous Gas Sign as Ominous Outcome Predictors Obata Katsuyoshi, M.D., Ph.D., Minobu Ozaki, M.D., Hiroyuki Matsuyama, M.D., Ph.D., Lizuka Hospital, Lizuka, Japan A 82-year-old female was admitted to our hospital for urinary tract infection. Four days after admission she developed to shock status. Abdominal CT showed hepatic portal venou gas sign and emphysematous esophagitis and gastritis associated with incarcerated obturator hernia.Emergent surgery was scheduled for hernia repair.Pre-operative medical co-morbities were acute kidney injury extension of PT-INR:4.45 septic shock status and aspiration pneumonia.Prior to anesthesia induction radial artery cannulation and naso-gastric tube suction were performed.Soon after tracheal intubation severe hypotension occurred. Though we tried to stabilize poor hemodyanamic state resuscitation failed eventually. We will present the ominous outcome predictors seen in this case. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM OB MC237 Anesthetic Management of a Parturient With a Liver Transplantation Sandeep Dhanjal, Martin Ismawan, M.D., Tiffany Orchard, M.D., Walter Reed National Military Medical Center, Bethesda, MD 30-year-old female G3P0020 EGA of 34+4 presented to Labor and Delivery for observation of preeclampsia. Medically history is complicated by hypertension primary sclerosing cholangitis requiring orthotopic liver transplant complicated by deep venous thrombosis. The patient was evaluated by the complex obstetric anesthesia service for chronic and acute hepatopathy in setting of pre-eclampsia. The patient was found to have no evidence of coagulopathy liver failure (ascites venous distension encephalopathy) or medication regimen that would preclude neuraxial anesthesia. She underwent combined spinal-epidural anesthesia without complications and successfully underwent cesarean delivery. She was discharged home on post-operative day two. Saturday, October 12 3:00 PM - 4:30 PM OB MC238 Anesthesia Management of Combined Cesarean Section and Radical Hysterectomy for Invasive Cervical Cancer During Pregnancy Tasneem Dohadwala, M.D., Virgil Manica, M.D., Tufts Medical Center, Boston, MA We report a case of a 35-year-old G4P3 female with a known diagnosis of locally invasive stage IB1 grade-2 endocervical adenocarcinoma who presented to the gynecology/oncology clinic at 14+ weeks gestation with her HIV-positive husband. Despite counseling she desired to continue with the pregnancy. Thus at 34 weeks gestation she had a planned C/section which was done under spinal anesthesia to honor the patient's desire to be awake for her daughter's delivery. For subsequent radical hysterectomy we converted to GETA with rapid sequence induction. An arterial line was placed for invasive monitoring. She remained hemodynamically stable throughout the case. Saturday, October 12 3:00 PM - 4:30 PM OB MC239 Anesthetic Management of a Parturient With Cardiovascular and Skeletal Complications of Marfan Syndrome for Cesarean Section Jennifer Dominguez, M.D., Terrence Allen, M.B. B.S., Linda Gray, M.D., Abigail Melnick, M.D., Holly Muir, M.D., Duke University, Durham, NC A 19-year-old G1P0 woman with Marfan syndrome a dilated aortic root hypertension obesity and scoliosis s/p Harrington rod placement from T5 to L4 presented for cesarean section at 37 weeks gestation. A spinal catheter was placed under CT-fluoroscopic guidance. After placement of an arterial catheter dosing of the spinal catheter did not produce adaquete anesthesia and general anesthesia was induced and maintained with an inhalational anesthetic and remifentanil to achieve hemodynamic stability. While neuraxial anesthesia is desirable in parturients with a dilated aortic root its use is complicated by the high rate of inadequate blocks in these patients. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM OB MC240 Anesthetic Management of a Parturient With Seckel Syndrome for Cesarean Section Ranita Donald, M.D., Vikas Kumar, M.D., Georgia Regents University, Augusta, GA 24-year-old parturient G1P0 at 37 weeks gestation with history of Seckel Syndrome presented in early labor for the cesarean section for cephalo-pelvic disproportion. Patient had typical features of Seckel Syndrome (bird-headed dwarfism mental retardation crowding of vertebra with scoliosis microcephaly micrognathia beaked nose with severely limited mouth opening and neck mobility). Otolaryngology consult earlier showed very difficult airway with complete right nasal obstruction very narrow left nasal passage retroflexed epiglottis and narrowed glottic inlet. Patient required awake tracheostomy (difficult tracheostomy) followed by cesarean under general anesthesia without any complication. Patient and baby were discharged home on third postoperative day. Saturday, October 12 3:00 PM - 4:30 PM OB MC241 Anesthetic Considerations and Management in a Mother Undergoing Intrauterine Fetal Thoracoamniotic Shunts for Bilateral Fetal Hydrothorax Farzad Ebrahimi, M.D., Sergio Gonzalez, M.D., N. Nick Knezevic, M.D., Ph.D., Advocate Illinois Masonic Medical Center, Chicago, IL A 37-year-old G2P1 woman was diagnosed with bilateral fetal hydrothorax at 29-weeks gestation. Fetal thoracocentesis performed under LA at 30-weeks resulted in re-accumulation of fluid within two weeks. A decision was made to perform ultrasound-guided percutaneous placement of bilateral fetal thoracoamniotic shunts as minimally invasive fetal surgery. The patient received small intermittent bolus doses of midazolam and fentanyl for intravenous sedation. An 8-French cook Pigtail catheter was deployed into the fetal thoracic cavity under US-guidance. The anesthetic goals for both the mother and fetus included maintaining hemodynamic stability maternal oxygenation normocarbia placental perfusion uterine relaxation and preparation for a potential C-section. Saturday, October 12 3:00 PM - 4:30 PM OB MC242 Bebulin Administration Before CSE Placement in a Parturient With Factor X Deficiency Ashley Eggers, Christopher Ciliberto, M.D., Laurent Bollag, M.D., Ruth Landau, M.D., University of Washington, Seattle, WA A 26-year-old nullipara with an autosomal dominant variation of Factor X Deficiency was induced at 39 weeks gestation and requested neuraxial analgesia. She had a history of significant bleeding during relatively minor procedures and had received Bebulin (Factor IX complex) on several occasions. After 24 hours of IV PCA remifentanil for early labor pain a Bebulin dose was given followed by an uneventful CSE. Following delivery the epidural was removed without issues and she was discharged from the hospital two days later. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM OB MC243 Anesthesia for Endovascular Repair of Coarctation of the Aorta in a Pregnant Woman With Mitral Stenosis. A Challenging Case for Mother and Fetus Renata Ferreira, M.D., Christopher Ciliberto, M.D., LaVone Simmons, M.D., Elisa Zaragoza-Macias, University of Washington, Seattle, WA 34-year-old female with coarctation of the aorta and moderate MV stenosis. Due to persistent hypertension at 20 weeks of gestation an endovascular stent placement was perfomed by a multidisciplinary team including maternal-fetal medicine interventional cardiology cardiothoracic anesthesia and obstetric anesthesia.Continuous fetal monitoring was performed. Upon extubation an episode of fetal asystole followed by prolonged fetal bradycardia was identified. The obstetric anesthesiologist administered ephedrine nitroglycerin and terbutaline. Upon administration of ephedrine mother developed hypertension and pulmonary edema treated with furosemide and non-invasive positive pressure. Appropriate fetal heart rate normalized. By discharge patient was normotensive on no medications. The pregnancy is ongoing. Saturday, October 12 3:00 PM - 4:30 PM OB MC244 Anesthetic Management of a Parturient With Klippel-Trenaunay Syndrome on Therapeutic Anticoagulation Melissa Flanigan, D.O., Monica Ata, D.O., Eric Massey, M.D., West Virginia University, Morgantown, WV 34-year-old parturient with a history of Klippel-Trenaunay Syndrome presents to our facility in preterm labor. On admission she was found to have extensive deep venous thrombosis of her left leg. She was anticoagulated with heparin during her stay. Multiple providers were consulted who educated the patient and gave her different options for labor analgesia. The patient ultimately decided on spinal anesthesia. Upon discontinuing the heparin and reaching normal coagulation values an intrathecal administration of duramorph with a low-dose isobaric bupivacaine was administered. She received adequate analgesia during her labor and subsequently had an uneventful delivery. Saturday, October 12 3:00 PM - 4:30 PM OB MC245 Epidural Anesthesia in a Patient With Idiopathic Fibrosing Mediastienitis Complicated With Obstruction of the Superior Vena Cava Karen Fleming, M.D., Fatimah Habib, M.D., Magdy Takla, M.D., Cooper University Hospital, Camden, NJ A 34-year-old G3P2 female with a history of morbid obesity and idiopathic fibrosing mediastinitis presented for induction of labor at 39 weeks gestation. The patient was seen in preadmission testing for anesthetic evaluation. On physical exam the patient had bilateral upper extremity swelling shortness of breath with exertion and obesity. New imaging was not recommended by pulmonology. A scheduled induction of labor with an epidural anesthesia was planned in coordination with the maternal-fetalmedicine team for high risk pregnancy. The epidural was kept at a low infusion rate. Every measure was taken to avoid general anesthesia in this patient. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM OB MC246 A Case of ECT in a Pregnant Patient Kenneth Fomberstein, M.D., Lars Helgeson, M.D., Yale-New Haven Hospital, New Haven, CT A 20-year-old female at 24 weeks gestational age presented for electroconvulsive therapy (ECT) in the PACU. ASA and fetal heart rate monitors were applied with normal readings. Methohexital & succinylcholine were used for intubation. Fetal decelerations to the 60s were noted after 2:30 minutes of seizure. Midazolam was administered and the seizure aborted after 2:50. The FHR tracing became difficult to obtain so the patient was taken to the OR where FHR was reacquired at 124. The patient was observed then extubated. Subsequent ECT treatments were induced with propofol with seizure durations <1:30 with no episodes of fetal bradycardia. Saturday, October 12 3:00 PM - 4:30 PM OB MC247 Management of Intraoperative Hypertensive Emergency Later rRevealed to be Undiagnosed Pheochromocytoma Marylin Fouche, M.D., University of Mississippi Medical Center, Jackson, MS 29-year-old female with history of chronic untreated hypertension and morbid obesity with pregnancy at 28 weeks presenting for emergent cesarean due to severely elevated pressures and preeclampsia. Arterial line pressures were not decreased after delivery of a viable fetus. Multiple IV anti-hypertensives at maximum doses and oral anti-hypertensives were not successful in decreased pressures. Despite therapy patient continued to have severe blood pressures with deteriorating mental status. Urine metanephrine levels obtained and were elevated. Abdominal CT scan revealed pheochromocytoma. Pressures improved with oral agents; total intensive care time 15 days. Patient then scheduled for removal of pheochromocytoma. Saturday, October 12 3:00 PM - 4:30 PM OB MC248 Management of Aortic Stenosis and Chest Pain in the Parturient Robert Freundlich, M.D., M.S., Vishrut Naik, M.D., Monica Servin, M.D., University of Michigan, Ann Arbor, MI A 23-year-old ASA 4 G2P1 presents at 25 weeks of gestation with a chief complaint of exertional chest pain. The patient has a history of severe aortic stenosis and mild mitral regurgitation status-post mechanical aortic and mitral valve replacement at age 13. She receives fonaparinux for prophylactic anticoagulation. She is admitted for evaluation and the obstetric anesthesiology service is consulted for recommendations for pre-delivery optimization. She denies signs and symptoms of heart failure. A TTE is performed and reveals a peak aortic gradient of 80 mmHg and a mean gradient of 50 mmHg. Left ventricular systolic function is normal. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM OB MC249 EXIT Delivery for the Difficult Fetal Airway Jessica Galey, M.D., Shobana Bharadwaj, M.B. B.S., University of Maryland, Baltimore, MD Two cases of EXIT delivery for fetal airway management are discussed. A 33 year-old patient was treated with intra-amniotic and intra-fetal-muscular injection of levothyroxine for a fetal goiter compressing trachea and a 36 year-old patient with a fetal neck mass causing tracheal deviation. Direct Laryngoscopy Rigid bronchoscopy Tracheostomy or EXIT to ECMO was the algorithm proposed for airway management while on placental perfusion. General anesthesia was initiated and uterine relaxation was provided with sevoflurane and nitroglycerin infusion and low dose phenylephrine to maintain maternal blood pressures. The times from uterine incision to clamping the umbilical cord were 25 and 13 minutes respectively. Saturday, October 12 3:00 PM - 4:30 PM OB MC250 Management Strategy for a Cesarean Delivery for a Parturient With Severe Cardiomyopathy With No Prenatal Care in Acute Distress Jacqueline Galvan, Heather Nixon, M.D., University of Illinois Hospital, Chicago, IL We present a case of a 22-year-old G2P1 at 33 weeks GA who was transferred from an OSH with progressive dyspnea chest pain and orthopnea with a PMH of cardiomyopathy (EF=35%) and no prenatal care. On admission her transthoracic echocardiogram showed an EF of 10% with PHTN (PAP 36mmHg) global hypokinesis and cardiomegaly. Due to her worsening condition and IUGR of the fetus a cesarean delivery was planned. In this medically challenging case with a high risk of mortality we describe our successful management strategy including echocardiography invasive monitoring beta blockers diuretics fluid restriction milrinone bolus and an inhalational induction. Saturday, October 12 3:00 PM - 4:30 PM OB MC251 Management of a Large Hemorrhagic Liver Adenoma in an Obese Parturient Jacqueline Galvan, M.D., Hokuto Nishioka, M.D., University of Illinois Hospital, Chicago, IL A 31-year-old obese parturient at 17 weeks gestation presented with abdominal pain and anemia requiring multiple blood transfusions. Her obstetric history was complicated by emesis gravidarum. Imaging studies revealed a large 10cm x 15cm hemorrhagic liver adenoma. Robotic-assisted laparoscopic excision of the mass was planned and it was successfully excised with minimal blood loss and without hemodynamic compromise. The parturient was extubated at the completion of the case with fetal heart tones at baseline. While resection of liver tumors in pregnancy is rare a careful anesthetic management is crucial to a successful outcome. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM OB MC252 Anesthetic Considerations for Amyotrophic Lateral Sclerosis in Pregnancy Harry Garcia, Student, Mohammed Abdel-Rahim, M.D., Gabriel Sarah, M.D., University of Miami Miller School of Medicine, Miami, FL A 27-year-old female G1P0 presented to her obstetrician at 10 weeks gestational age complaining of weakness in the right upper and left lower extremities. Conclusive workup led to the diagnosis of Amyotrophic Lateral Sclerosis. By 30 weeks gestational age she developed dyspnea at rest and while supine. At a multidisciplinary meeting the decision was made to schedule delivery by C-section at 34 weeks gestational age. However respiratory decompensation required C-section at 33 weeks gestational age. To date the literature reports only 11 similar pregnancies. Here we present the perioperative management anesthetic implications and outcomes of this rare and debilitating disease. Saturday, October 12 3:00 PM - 4:30 PM RA MC253 Continuous Left Stellate Ganglion Block for Intractable Angina Ryan Ensminger, D.O., Linda Le-Wendling, M.D., University of Florida, Gainesville, FL Our patient is a 60-year-old male with coronary artery disease post CABG in 2003 and 2012 fibromyalgia and intractable chest pain. Previously the patient had undergone cervical spinal cord stimulator placement for his chest pain which eventually became ineffective. Despite Nitroglycerin infusion and intravenous dilaudid the patient continued to have severe angina though he was not a candidate for percutaneous coronary intervention or surgical revascularization. A continuous left stellate ganglion block was placed under real-time ultrasound guidance and an infusion of ropivicaine initiated with relief of his angina. The patient refused alcohol ablation of the stellate ganglion. Saturday, October 12 3:00 PM - 4:30 PM RA MC254 Patient With a Difficult Airway Undergoing Percutaneous Endoscopic Gastrostomy Tube Placement Under Ultrasound-Guided Bilateral Rectus Sheath Block Shahla Escobar, M.D., Enrique Escobar, M.D., Irina Gasanova, M.D., Ph.D., Amin Kamali, D.O., University of Texas Southwestern Medical Center, Dallas, TX A 63-year-old male with a past medical history significant for squamous cell carcinoma of the tongue presented to the interventional radiology suite for a midline percutaneous endoscopic gastrostomy tube placement for malnourishment. His preoperative physical examination was significant for a Mallampati class 4 airway small mouth opening short thyromental distance and limited neck mobility. Intravenous sedation was initiated with a dexmedotomidine infusion. A bilateral ultrasound-guided rectus sheath block at the T7 and T9 dermatome levels was performed. A mid-abdominal sensory block overlying the T7-T10 nerve dermatomes was achieved. His procedure was successfully completed without local anesthetic supplementation.

Pain score 9 refractory to tramadol dipyrone ketorolac and morphine. Reduction in pain score 9 to 3 in 45 minutes after intravenous dextrocetamine 0.1 mg.kg-1 and lidocaine 2 mg.kg-1 infused over 30 minutes. Lack of pain within 3 days. Pregabalin 225 mg given orally per day for 1 month. No neuropathic manifestations in 16 weeks of follow-up. Saturday, October 12 3:00 PM - 4:30 PM RA MC256 Removal of a Thoracic Epidural Catheter After Cardiac Surgery While on Angiomax Daniel Francis, M.D., Mahammad Hussain, M.D., UT Houston- Texas Medical Center, Houston, TX In this case we describe a 57-year-old female who received a pre-operative Thoracic Epidural for a multivessel CABG. Her post-operative course was complicated by severe thrombocytopenia concern for HIT the need for life sustaining mechanical support devices and continuous anti-coagulation. The patient was transferred to our facility for higher level of care on angiomax due to concern for HIT. The Acute Pain service was consulted to manage safe removal of the retained thoracic epidural catheter. Saturday, October 12 3:00 PM - 4:30 PM RA MC257 Bilateral Tap blocks for an Open Laparatomy Scott Goldhaber, D.O., Chaiyapat Charoonbara, M.D., Jean Eloy, M.D., Sean McGuirt, Student, UMDNJNJMS, Newark, NJ Transversus abdominis plane (TAP) block is a relatively new regional technique. It remains underutilized despite its ease of use. It involves injecting local anesthetic between the internal oblique and transversus abdominis layers. While many studies demonstrate efficacy in postop analgesia few reports evaluate its use as a regional technique intraoperatively. We present a case of a 70-year-old man who underwent exploratory laparotomy with Bilateral TAP blocks under sedation. Saturday, October 12 3:00 PM - 4:30 PM RA MC258 Postoperative Rescue Sciatic Nerve Block Performed Using Stimulation Technique for Treatment of Intractable Stump and Phantom Limb Pain Following Acute Traumatic Amputation of Foot and Ankle Jonathan Grainger, M.D., Michael Hawryschuk, M.D., University of Cincinnati Medical Center, Dayton, KY We present a case employing a rescue sciatic nerve block using nerve stimulation for treatment of intractable postoperative pain following emergent below knee amputation. Nerve stimulation is rarely used in this scenario secondary to inability to elicit a motor response. Using our understanding of phantom limb pain we were able to illicit a sensation of sensory nerve stimulation in the non-existent foot. Despite no evidence of motor stimulation below the knee our patient was pain free within Copyright © 2013 American Society of Anesthesiologists minutes. We believe that this stimulation technique may be an alternate end-point if no motor response can be elicited for post-operative analgesia. Saturday, October 12 3:00 PM - 4:30 PM RA MC259 A Case of Transverse Sinus Venous Thrombosis After Post Dural Puncture Headache Maged Guirguis, M.D., Samuel Samuel, M.D., Cleveland Clinic Foundation, Cleveland, OH 28-year-old patient developed headache after her second C6-C7 inter-laminar cervical epidural steroid injection with documented dural puncture who presented with classic features of PDPH refractory to conservative measures. Patient failed both lumbar and cervical epidural blood patch. MRI brain showed a focal filling defect within the left transverse sinus. MRV showed absent flow-related enhancement in a large portion of the left transverse sinus. Initiating heparin infusion paralleled with subsiding of symptoms.Full hypercoagulability panel showed elevated factor-VIII. Patient was started on warfarin.MRVs in 3 and 6 months were performed and showed partial re-canalization in the left transverse sinus. Saturday, October 12 3:00 PM - 4:30 PM RA MC260 Transient Horner Syndrome and Unilateral Brachial Plexus Blockade Following Epidural Infusion in a Thoracotomy Patient Jason Hahn, M.D., Luminita Tureanu, M.D., Northwestern University, Chicago, IL Epidural catheterization may cause significant adverse effects perioperatively. We describe a case of transient Horner syndrome and unilateral brachial plexus blockade following epidural infusion of 0.1% bupivacaine with 10mcg/ml hydromorphone in a thoracotomy patient. The differential diagnosis included CNS pathology brachial plexus injury and nerve root involvement. The symptoms resolved with halving the epidural infusion and continuing with hydromorphone only. Such symptoms most likely due to second order sympathetic neuronal involvement are reported rarely in the literature. Possible contributing factors include positioning sympathetic fiber hypersensitivity and anatomic variations. Early recognition may facilitate clinical decision making and avoid unnecessary diagnostic workup. Saturday, October 12 3:00 PM - 4:30 PM RA MC261 It Hurts Where My Toes Would Be if They Were There: Phantom Pain After Transmetatarsal Amputation Brittani Hale, M.D., Ellen Flanagan, M.D., Duke University, Durham, NC A 28-year-old female with lupus and ESRD presented for right femoral AV graft placement. Postoperative course was complicated by acute vasospastic episode of the right lower extremity. Despite argatroban therapy gangrene developed requiring transmetatarsal amputation under general anesthesia with PCA post-operative analgesia. Regional analgesia was not considered due to patient's anticoagulation status. On POD3 the Pain Service was consulted for 10/10 lower extremity pain. Saphenous and popliteal nerve catheters were placed after single shot blocks for comfort. Despite complete sensory and motor blockade the patient continued to report severe pain where my toes would be if they were there.

An epidural catheter was placed preoperatively for postoperative pain control. On postoperative day 2 significant resistance was met during catheter removal despite multiple maneuvers classically used to aid in catheter removal. The patient was placed prone on a portable Wilson frame and using fluoroscopy the catheter location was identified and the catheter ultimately removed. Inspection revealed a single loop knot less than 1 cm from the catheter tip. We describe a possible mechanism for knotting during placement and review approaches to removal of entrained epidural catheters. Saturday, October 12 3:00 PM - 4:30 PM RA MC263 Anesthetic Management of a Thrombocytopenic Patient on Suboxone Maintenance for Splenectomy Yili Huang, D.O., Balazs Horvath, M.D., Robert Lagasse, M.D., Yale University School of Medicine, New Haven, CT Suboxone has gained popularity as a treatment for opioid addiction and chronic pain but its partial agonist/antagonist activity makes management of perioperative analgesia difficult. Premorbid conditions and surgical requirements can also make the use of regional anesthesia controversial in these patients. Our patient is a former opioid addict previously managed with a physician-monitored methadone program before transitioning herself to Suboxone maintenance without the input of a physician. Her history includes pulmonary and portal hypertension secondary to cirrhosis and her preadmission testing revealed a platelet count of 55 000. She is scheduled to undergo splenectomy and possible spenorenal shunt with postoperative heparinization. Saturday, October 12 3:00 PM - 4:30 PM RA MC264 Neuraxial Anesthesia in a Left Ventricular Assist Device Patient Undergoing Gynecologic Surgery Jacob Hummel, M.D., Brent Dilts, Santiago Gomez, Tulane University, New Orleans, LA A 33-year-old female with severe non-ischemic cardiomyopathy chronically supported by an LVAD underwent a salpingo-oopherectomy to remove an ovarian mass. Neuraxial anesthesia was conducted throughout the case wtih an epidural and dosed with 0.5% ropivacaine and 2% lidocaine along with an intravenous infusion consisting of propofol and ketamine for sedation. The challenge of maintaining optimal hemodynamics in the presence of neuraxial anesthesia vasodilation and extensive blood loss was significant. The patient was admitted to the ICU for vasopressor support and monitoring but was quickly weaned off vasopressors. The patient was discharged home on postoperative day 3 in stable condition.

Placed on an Oxygen Facemask at 6 liter/ minute. A low dose Propofol Infusion was started (40 mcg/kg/min.) The classicly described method of Intercostal block was performed at the posterior angle of each rib T4-12 by first palpating each rib then hitting it with a 25 ga needle and walking off the inferior aspect. 4 ml of Bupivacaine 0.5% was injected into each neurovascular bundle. The patient tolerated this well and went on to have Visually Aided Thoracic Surgery (VATS) drainage of empyema. Saturday, October 12 3:00 PM - 4:30 PM RA MC266 Transient Urinary Incontinence After Single Shot Sciatic Nerve Block Christina Julian, M.D., Stephen Howell, M.D., James Sadler, M.D., West Virginia University, Morgantown, WV A 38-year-old female patient experienced transient urinary incontinence after a pre-operative single shot sciatic nerve block for posterior tibial tendon debridement and tenosynovectomy. The block was performed via the classic posterior Labat approach stimulating needle was utilized and 20 mL of Bupivicaine 0.5% was injected without complication. In the 12-hour period immediately post-op the patient complained of significant perineal numbness and experienced 4 episodes of urinary incontinence. As the effects of the block dissipated the patient slowly regained sensation and the ability to void completely returned by 16 hours post block. She has no residual effects. Saturday, October 12 3:00 PM - 4:30 PM RA MC267 Successful Treatment With Intralipid of Central and Peripheral Nervous System Symptoms Resulting From Local Anesthetic Overdose Ihab Kamel, M.D., Rodger Barnette, M.D., Gaurav Trehan, M.D., Temple University Hospital, Philadelphia, PA A 51-year-old 74 kg female scheduled for transvaginal tape placement under general anesthesia had 80 mL of 0.5% bupivacaine with epinephrine injected at the surgical site. In the PACU the patient experienced dizziness posturing and occulogyric symptoms. The patient could not feel or move her left lower extremity. On examination the left leg showed rigidity loss of motor strength and decreased sensation. The patient was treated with 500 mL of 20% intralipid IV (bolus and infusion) over 21 minutes. After treatment neurologic symptoms resolved and the patient had restoration of motor function and sensation to the left lower extremity.

After completion of the continuous infusion of local anaesthetic on the third post-operative day the nurse attempted to remove the catheter as instructed. But it could not be removed causing pain and discomfort to the patient leading to removal of the catheter by a plastic surgeon under local anaesthesia. On exposure a fascial band was found trapped between the distal coils of the catheter which was released and the catheter removed. The patient recovered without any neurological deficit. Saturday, October 12 3:00 PM - 4:30 PM RA MC269 Stuck on You Muthuraj Kanakaraj, Madhu Shankar Balasubramaniam, M.D., F.R.C.A, Asoka Balage, M.D., F.R.C.A, Malgorzata Jaworskagrajek, M.D., F.R.C.A, Reginald Edward, M.D., F.R.C.A, Hull and East Yorkshire Hospitals NHS Trust, Hull, United Kingdom An 18-year-old female patient with ultrasound guided adductor canal perineural catheter for anterior cruciate ligament repair was discharged home with continuous infusion by an elastomeric pump along with written and verbal instructions on catheter care and removal. At the end of the infusion when the patient attempted removal of the catheter the metal catheter uncoiled and got stuck. She contacted the anaesthesiologist and needed admission to hospital for catheter removal by plastic surgeons under local anaesthesia. The coils were found snagged on the fascia and had to be disengaged and removed. The patient recovered uneventfully without any neurological deficit. Saturday, October 12 3:00 PM - 4:30 PM RA MC270 Dabigatran: To bleed or Not to Bleed Nakiyah Knibbs, Michael Anderson, M.D., Mount Sinai Medical Center, New York, NY 65-year-old female with hypertension PVD recurrent DVT/PEs and renal insufficiency on dabigatran presents for knee revision for infection with systemic sepsis three weeks prior at an outside hospital. Significant blood loss was anticipated as her PVD precluded tourniquet use. Her last dabigatran dose was 4 days prior but her PTT and INR remained elevated (47.3 and 1.4). A thrombin time (TT) was sent and was 2 times normal. Because of dabigatran's irreversibility the case was delayed and TT monitored until normalized. The case proceeded 3 days later without incident. Copyright © 2013 American Society of Anesthesiologists Saturday, October 12 3:00 PM - 4:30 PM RA MC271 Combined Interscalene and Superficial Cervical Plexus Blocks for Postoperative Analgesia for Clavicular Surgery - A Novel Approach Sudheera Kokkada Sathyanarayana, M.D., Karina Gritsenko, M.D., Konrad Gruson, M.D., Boleslav Kosharskyy, M.D., Naum Shaparin, M.D., Montefiore Medical Center Albert Einstein College of Medicine, Bronx, NY Regional anesthesia for clavicle surgery is not well described in literature. This case series describes 4 patients undergoing open clavicle surgery who received preinduction ultrasound-guided interscalene brachial plexus and superficial cervical plexus nerve blocks requiring minimal postoperative analgesics. Intraoperatively balanced general anesthesia was provided with induction narcotic doses only; postoperative day 1 follow-up indicated excellent post-operative analgesia no narcotics in PACU no pain for 24 hours. This case series illustrates effective regional techniques which allow for improved patient satisfaction decreased narcotic use no pain on ambulation to home and transition to successful PO regimen. A prospective observational study is planned. Saturday, October 12 3:00 PM - 4:30 PM RA MC272 Cranial Nerve Paresis Following Shoulder Surgery: A Cause Analysis Molly Kraus, M.D., Rachel Cain, Renee Caswell, M.D., David Rosenfeld, M.D., Mayo Clinic, Phoenix, AZ A retrospective chart review of cranial nerve dysfunction following shoulder surgery was performed with analysis of operative indication and technique regional anesthesia characteristics of neurapraxia and postoperative course. Three patients with cranial nerve paresis following shoulder surgery were identified. All patients underwent ipsilateral preoperative ultrasound-guided interscalene brachial plexus block with ropivacaine. All surgeries were performed in the beach-chair position. Cranial nerve paresis was noted immediately postoperatively. Affected nerves included ipsilateral hypoglossal contralateral hypoglossal and ipsilateral hypoglossal and vagus. Intraoperative patient positioning as opposed to preoperative regional nerve block or operative technique is the most likely causative factor. Saturday, October 12 3:00 PM - 4:30 PM RA MC273 Extraction of A Knotted Interscalene Catheter Neha Kumar, M.D., Christina Jeng, M.D., Icahn School of Medicine at Mount Sinai, New York, NY A 61-year-old female presented for shoulder arthroplasty. Ultrasound-guided interscalene catheter was placed for perioperative analgesia. Post-operative day two the catheter could not be pulled at bedside. Peripheral catheter entrapment is a rare occurrence; case reports describe catheters hooking or kinking around the brachial plexus where forceful extraction risks permanent nerve injury. Thus the patient was monitored for dysesthesias during all extraction attempts. ENT was involved imaging obtained and it was decided Orthopedics would remove the catheter in the operating room. Effective communication among pain management specialists anesthesiologists surgeons radiologists and the patient resulted in a satisfactory outcome.

Traditional management includes endotracheal intubation high flow jet ventilation or spontaneous ventilation. Our airway management technique included a method of total intravenous anesthesia with spontaneous ventilation along with intermittent endotracheal intubation to provide optimal operating conditions for the surgeon while maintaining airway protection of the patient. Saturday, October 12 3:00 PM - 4:30 PM AM MC275 Severe Masseter Spasm & Stridor From Muscle Rigidity Associated With the Patient With Lewy Body Dementia Won Chee, M.D., The Montefiore Medical Center & Albert Eintein College of Medicine, Bronx, NY A 52-year-old female was scheduled for multiple tooth extractions under general anesthesia. Her past medical history was significant for Lewy body dementia diagnosed 3 years ago. The disease had severely impaired her neurological function both cognitive and motor; she could neither communicate with others nor care for herself from generalized muscle rigidity . Her medications included Sinemet. During emergence from anesthesia the patient manifested a severe masseter muscle spasm. After extubation a loud \stridor-like\" sound was heard but without visible airway obstruction. Eventually administration of Sinemet via an NG tube resolved all the symptoms." Saturday, October 12 3:00 PM - 4:30 PM AM MC276 Postoperative Stridor: A Challenging Diagnosis Ben Cobb, M.D., Katie Podorean, D.O., Irene Rozet, M.D., University of Washington, Seattle, WA Reintubation of the patient's airway in the immediate postoperative period increases morbidity and mortality. We present a case of postoperative stridor of multifactorial nature including paradoxical vocal cord motion (PVCM) abnormality. A 47-year-old ASA III female after uneventful general anesthesia for outpatient hysteroscopy developed stridor peri-oral swelling and respiratory depression. After unsuccessful conservative management for ketorolac allergy her airway was reintubated. After 48 hours repeated fiberoptic examination revealed PVCM. The patient was extubated with non-improved stridor and was referred to speech therapy for ongoing treatment. In middle-age women PVCM should be considered as a cause of stridor. Saturday, October 12 3:00 PM - 4:30 PM AM MC277 An Iatrogenic Airway Obstruction in a Former IV Drug User - Abbe Flap Inset Bryan Currie, D.O., Sanjib Adhikary, M.D., Pennsylvania State University Hershey Med Ctr, Hershey, PA A 31-year-old man underwent a cleft lip repair with unsatisfactory results. An Abbe flap was created from the philtrum to the lower lip. He presents for inset of the Abbe flap. Airway exam was remarkable for midline Abbe flap (upper to lower lip) resulting in extremely limited mouth opening. Contributing to Copyright © 2013 American Society of Anesthesiologists the complexity of this case was difficult IV access in this former IV drug user and his demand for a mask induction before IV placement. A mask induction with nitrous oxide was performed before intravenous access maintaining spontaneous ventilation. An asleep nasal fiberoptic intubation was then performed. Saturday, October 12 3:00 PM - 4:30 PM AM MC278 Anesthetic Management of a Patient With Charcot Marie Tooth Disease Type 2 and Soy Allergy Presenting for Laparoscopic Paraesophageal Hernia Repair Anis Dizdarevic, M.D., Columbia University, New York, NY 67-year-old woman with a history of Charcot Marie Tooth Disease Type 2 with associated peripheral neuropathy and bilateral lower and upper extremity pain presents for a laparoscopic repair of paraesophegeal hernia with mash and fundoplication. Patient also reports an unknown allergic reaction to soy and peanuts. This case report describes the anesthetic evaluation and considerations in Charcot Marie Tooth Disease association between soy and peanut allergy and risk of reaction after propofol administration analysis of literature and evidence and finally our successful anesthetic technique for this case. Saturday, October 12 3:00 PM - 4:30 PM AM MC279 Postoperative Loss of Taste and Smell Kelly Elterman, M.D., Richard Urman, M.D., M.B.A., Brigham and Women's Hospital, Boston, MA Alterations in taste and smell including but not limited to anosmia ageusia hypogeusia and dysgeusia have been associated with various medications including anesthetic agents. These symptoms typically occur 1-2 weeks after medication administration and last several months. Our patient a 61-year-old woman with no neurologic history or prior anesthetics underwent laparoscopic BSO for an ovarian mass and developed anosmia and ageusia on POD 1. Intraoperatively she received midazolam fentanyl propofol vecuronium sevoflurane and scopolamine. Her symptoms resolved completely by POD 3. Anesthesiologists should be aware of this unusual postoperative phenomenon which may impact patient satisfaction and quality of life. Saturday, October 12 3:00 PM - 4:30 PM AM MC280 Ventricular Tachycardia After Prone Positioning in Percutaneous Nephrolithotripsy in a Patient With a History of Right Bundle Branch Block and Newly Diagnosed Bifasicular Block Karen Fleming, M.D., Irwin Gratz, D.O., Cooper University Hospital, Camden, NJ A 73-year-old female with a history of hypertension diabetes morbid obesity and right bundle branch block was scheduled for percutaneous nephrolithotripsy. The patient was seen in pre-admission testing because of dyspnea on exertion. An EKG performed in pre-admission testing showed a new bifasicular heart block. After induction the patient was placed prone. Within 5 minutes the patient experienced 15 beats of ventricular tachycardia. Surgery was aborted; the patient was placed supine and spontaneously converted to sinus rhythm. Cardiology was consulted and concluded that this was artifact. The patient remained in the hospital for 24h observation and discharged home.

ACS develops once the intraabdominal pressure increases to 20-25 mmHg and is characterized by increased airway pressures inadequate ventilation and oxygenation altered renal function and hemodynamic instability. This case report details a 79-year-old male who developed acute ACS secondary to extraperitoneal bladder rupture and subsequent intraperitoneal tear during transurethral resection of the prostate (TURP) under general anesthesia. This case discusses his diagnoses and management which included re-intubation emergent exploratory laparotomy and drainage of irrigation fluid. Saturday, October 12 3:00 PM - 4:30 PM AM MC282 Refractory Postoperative Hypotension in the Ambulatory Setting After TAP Block for Inguinal Herniorrhaphy (Was it the TAP Block?) Christopher Godlewski, M.D., Tilak Raj, M.D., Thomas Tinker, M.D., University of Oklahoma Health Science Center, Oklahoma City, OK We present a 54-year-old patient who underwent inguinal herniorrhaphy under GETA with TAP (transversus abdominis plane) block for postoperative analgesia in our Ambulatory Surgery Center. In PACU he developed severe (systolic 60mmHg) refractory hypotension; he remained awake and conversant. Hypotension did not respond to treatment with fluids and pressors nor did it affect his consciousness. The prolonged and severe nature of the problem warranted admission to the ICU at the main hospital. Could the TAP block cause this? We discuss the differential diagnosis and management of such a problem and reveal the pathology responsible for this enigmatic problem. Saturday, October 12 3:00 PM - 4:30 PM AM MC283 Humerus Fracture Repair in a Patient With Advanced Multisystem Dysfunction in an Ambulatory Surgery Setting. Timothy Harwood, M.D., Wake Forest University, Winston-Salem, NC A 64-year-old man weighing 92 kg was scheduled in our ambulatory surgery center for a humeral head ORIF after a fracture. PMH included CAD with CABG/stents CHF with diastolic dysfunction and pleural effusions and BNP 249 DM with renal insufficiency PVD with CEA OSA but he cannot use CPAP. Because of these risk factors we chose a continuous ISB and superficial cervical plexus block for surgical anesthesia with a short-acting LA until we were assured he could tolerate the phrenic block. The ISB catheter was used for postoperative analgesia and the patient was discharged well on POD 1.

Induction of anesthesia was uneventful. Surgery was performed with a hysteroscope and bipolar cautery loop. During surgery the hysteroscope fluid bag was changed. Suddenly the ETCO2 decreased from 30 to 9 blood pressure dropped to 60/40 and the pulse increased to 110. An air embolus entrained by the hysteroscope into the uterine veins was suspected. Epinephrine was administered. The blood pressure increased to 130/75. The patient emerged from anesthesia moving all extremities. Within 2 hours she was alert and oriented hemodynamically stable and ready for discharge. Saturday, October 12 3:00 PM - 4:30 PM AM MC285 Management of an Unanticipated Difficult Airway Secondary to Ventral Osteophytes: A Case Report Jason Hoyos, D.O., Amy Kamat, M.D., Christina Matadial, M.D., University of Miami/Jackson Memorial Hospital, Miami, FL This report describes a case in which a large ventral osteophyte resulted in obstruction of the upper airway and difficult intubation. This structure was visualized while attempting to intubate a 54-year-old man presenting for a radical prostatectomy who had no prior imaging studies. In this case initial techniques were performed including an MAC blade and Storz rigid laryngoscope which proved to be unsuccessful. Eventually a successful hybrid technique was attempted using the rigid fiberoptic scope and the flexible fiberoptic scope together allowing visualization of the structures and appropriate navigation around the obstruction. Saturday, October 12 3:00 PM - 4:30 PM AM MC286 Airway Management in a Morbidly Obese Patient With OSA for Drug-Induced Sleep Endoscopy and Uvulopalatopharyngoplasty Zeena Husain, Quisqueya Palacios, M.D., Baylor College of Medicine, Houston, TX Drug-induced sleep nasal endoscopy (DISE) prior to uvulopalatopharyngoplasty for obstructive sleep apnea (OSA) presents anesthesia care providers with clinical challenges for airway management in high risk patients with significant comorbidities. The majority of OSA patients are obese with potentially difficult airways. Although RSI is ideal DISE is the opposite with prolonged airway obstruction an unsecured airway and ineffective oxygen delivery in a patient without protective airway reflexes. It is imperative to anticipate and plan for possible complications during DISE such as difficult intubation risk of aspiration respiratory depression and inadequate anesthesia all while maintaining constant communication with the surgeons.

During an extensive pre-op interview it was discovered that the patient's mastocytosis was uncontrolled contrary to his medical record. His surgery was postponed one month while his condition was stabilized with cromolyn prednisone diphenhydramine and promethazine. The purpose of this case report is to discuss the importance of thorough pre-op evaluation and management using an example of a patient undergoing general anesthesia presenting with mastocytosis. Saturday, October 12 3:00 PM - 4:30 PM AM MC288 Great Auricular Neuropraxia With Beach Chair Position: A Case Report Miinal Joshi, M.D., Mohammad Abidi, M.D., H Kamath, M.D., Joel Yarmush, M.D., Joseph Schianodicola, M.D., NY Methodist Hospital, Brooklyn, NY Arthroscopy is a frequent method for shoulder procedures. We report a case of greater auricular neuropraxia associated with horseshoe headrest used for shoulder surgery in beach chair position. In this case an interscalene block was performed under ultrasound guidance and a nerve stimulator technique. The patient was comfortable through out the procedure for 143 minutes and discharged home. Following day the patient described numbness in the lobule of the left ear extending to the mandibular angle. MRI studies were negative. Injury of the greater auricular nerve was diagnosed. After five months her symptoms decreased to the point of minimal irritation.

Vikram Chawa, M.D., Hui Yuan, M.D., Saint Louis University, St. Louis, MO This case is about a 75-year-old male with greater than four Metabolic Equivalents of Task and without any risk factors from the Revised Cardiac Risk Index who was scheduled for open reduction internal fixation of bilateral femoral fractures. Upon requesting medication for his fracture pain our patient was found to also have chest pain and ischemic changes on ECG. After standard acute treatment was administered coronary catheterization was performed which showed severe triple vessel disease. This underlying severe disease was symptomatically unmasked secondary to anxiety pain and anemia. Surgery was delayed until patient underwent revascularization. Sunday, October 13 8:00 AM - 9:30 AM FA MC290 Pneumothorax Following Laparoscopic Extraperitoneal Inguinal Hernia Repair Amanda Chehval, D.O., Anjali Patel, D.O., Saint Louis University, Saint Louis, MO Pneumothorax is a rare complication of laparoscopic surgery due to the extravasation of insufflated carbon dioxide into the pleural space. We describe a 31-year-old healthy male who presented for laparoscopic repair of a right inguinal hernia. After insufflation with CO2 the ETCO2 and peak airway pressures began to increase with decreased breath sounds bilaterally. The patient remained hemodynamically stable and the surgery was completed. A post-operative chest x-ray revealed bilateral pneumothoraces. The patient was admitted overnight for observation and chest x-ray the following day demonstrated resolution of the pneumothoraces. He was discharged without further complication. Sunday, October 13 8:00 AM - 9:30 AM FA MC291 En Bloc Resection Neck Dissection and Rectus Abdominis Microvascular Free Flap for Management of Recurrent Right Periorbital Sarcoma Tiffany Chen, M.D., NYU Langone Medical Center, New York, NY A 67-year-old man with history of HTN HLD CAD s/p MI complete heart block s/p PPM IgA nephritis and right sphenoid wing meningioma status post resection and radiation therapy in 2008 presents with increasing right periorbital swelling. The patient underwent right composite craniofacial resection and orbital exenteration orbital and zygomatic osteotomies frontotemporal craniectomy lumbar drain placement and reconstruction with a rectus abdominis microvascular free flap. The patient experienced mental status changes on POD 5. NCHCT showed edema and small intraparenchymal hemorrhage with mild midline shift and mass effect. Lumbar drain was clamped with improvement in mental status.

Airway is a mallampati class 3 with limited range of motion. CT shows large hilar mass obstructing left main bronchus and separate 10cm diameter goiter causing proximal tracheal stenosis to 5 mm. After awake flexible bronchoscopy rigid bronchoscope was placed and the bronchial tumor was partially ablated by laser. Then a left main bronchus stent was placed. Next tracheal stenosis was managed by placement of another stent. After removal of rigid bronchoscope LMA was placed and removed when patient woke up. Sunday, October 13 8:00 AM - 9:30 AM FA MC294 Split Thickness Skin Grafting for a Circumferential Neck Burn in the Ecuadorian Jungle: A Case Report Chien Chow, M.D., Rady Children's Hospital, San Diego, CA, Robert Stephenson, D.O., St. Elizabeth's Medical Center, Boston, MA Our patient is a 49-year-old Ecuadorian mother of 9 who sustained circumferential flame burns to her neck from a kitchen stove accident several years ago. In this medically challenging case we discuss the unique challenges of securing an expected difficult airway during a medical missions trip in the Ecuadorian jungle where advanced airway equipment like fiberoptic bronchoscopy or video-assisted laryngoscopy is not available. By carefully titrating sedation with intravenous anesthetic agents that did not induce apnea we maintained the patient's oxygen stores and allowed adequate time to secure the patient's airway. Her surgery and post-anesthetic course were uneventful. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 8:00 AM - 9:30 AM FA MC295 Management of the Airway in the Pierre Robin Syndrome Using C-Mac D Blade and Fiberoptic Scope Elif Cingi, Nathan T. Beerling, M.D., University of Minnesota, Minneapolis, MN Airway management with Pierre Robin syndrome is diagnostically and therapeutically challenging. It is a rare condition first described by the Pierre Robin in 1923. The severity of the syndrome varies widely and associated upper airway obstruction is the most difficult problem to overcome. The triad of glossoptosis micrognathia and cleft palate provides a challenge in airway management for the anesthesiologist in newborn. Adult Pierre Robin syndrome patients with multiple corrective surgeries may have altered normal anatomy. We present a case in which the nasal airway was successfully managed with a C-MAC D blade and fiberoptic scope while patient was awake. Sunday, October 13 8:00 AM - 9:30 AM FA MC296 Management of Tracheostomy Migration in the Pickwickian Patient Catherine Cleland, M.D., Christopher Jackson, M.D., George Washington University Hospital, Washingon, DC A 24-year-old ventilator dependent morbidly obese female with obesity hypoventilation syndrome and known difficult airway presented one day status post tracheostomy with decreasing tidal volumes and an air leak. The trach had migrated anteriorly and the patient was taken emergently to the OR. Prior to attempted exchange of the trach over a pediatric tube exchanger a Glidescope was placed in an attempt to visualize the cords (grade 4 view). Trach exchange was unsuccessful tidal volumes were low and oxygen saturation started to decrease. Airway management was then turned over to the Anesthesia team followed by successful endotracheal intubation. Sunday, October 13 8:00 AM - 9:30 AM FA MC297 Utilization of Continuous Ventilation During Intubation of an Unfavorable Airway Catherine Cleland, Chris Edwards, M.D., George Washington University Hospital, Washington, DC A 49-year-old male with a history of cirrhosis and esophageal varices presented to the operating room with a cervical abscess from breakdown of cervical hardware. Risks and benefits of an awake intubation were discussed with the patient who ultimately refused. The patient was induced with propofol lidocaine and fentanyl and a 4.5 intubating LMA was placed with the c-collar still in position. Spontaneous respirations were maintained with the use of a bronchoscopy elbow. A 7.0 ETT was placed through the LMA guided with a fiberoptic scope. End-tidal CO2 was confirmed before and after the LMA was removed.

The patient fired two large caliber rounds under his chin essentially removing his mid face obscuring all relevant upper airway anatomy. The surgical team requested an intubation from above be maintained during their revision to tracheostomy. We discuss our approach to intubation in a patient with obliterated upper airway anatomy hemorrhage and florid edema Sunday, October 13 8:00 AM - 9:30 AM FA MC299 Perioperative Management for Extensive Liver Resection in a Patient With Polycystic Liver Disease Major Cunningham, M.D., Hui Yuan, M.D., St. Louis University, St. Louis, MO This patient was a 47-year-old female with polycystic kidney and liver disease with destruction of her right liver by giant size of cysts causing abdominal pain and dyspnea. With previous liver resection she presented for repeat extended right hepatectomy. An epidural catheter was placed preoperatively. In OR hemodynamics status were monitored with A-line and CVP. For reducing the blood loss CVP was maintained at the lowest level and BP was supported with vasopressin. Hemostasis was managed by real time of thromboelastography and significant blood loss was replaced with the transfusion. The patient was recovered after operation without any complications. Sunday, October 13 8:00 AM - 9:30 AM FA MC300 Medical and Ethical Challenges in a Patient With a Known History of Anaphylactic Reaction to Contrast Dye Presenting for Endovascular Surgery Nishita Dalal, Robert Isaak, D.O., University of North Carolina, Chapel Hill, NC 80-year-old female with a history of TAAA s/p TEVAR and AAA s/p EVAR presented for repeat fenestrated TEVAR of TAAA. Patient had a known history of an anaphylactic reaction to IV contrast dye and was prophylatically pretreated prior to the procedure. Despite pretreatment the patient had an anaphylactic reaction following administration of 3ml of IV contrast. Following a lengthy discussion amongst the surgical team and with the family the decision was made to continue the surgery with the use of gadolinium dye. The patient's postoperative course was complicated by a mesenteric embolic event requiring small bowel resection.

She reported several allergies to pain medication including anaphylaxis to demerol dilaudid codeine morphine fentanyl and naproxen. Consequently this case presents challenges to safely provide analgesia fosters discussion regarding the prevalence of true opiate allergies questions the possibility of pre-anesthetic allergy testing and exemplifies the long term consequences of incorrectly labeling a patient with a drug allergy. Sunday, October 13 8:00 AM - 9:30 AM FA MC302 Acute Post-Intubation Airway Obstruction Following a TIPS Procedure Maurice Davis, M.D., Timothy Schmale, M.D., Beaumont Health System, Royal Oak, MI A 47-year-old male with history of alcohol/hepatitis C-induced end-stage liver disease (MELD 23) endstage renal disease diabetes and bilateral vocal cord paralysis underwent a 7-hour TIPS procedure. Patient was extubated with reassuring cuff leak test but reintubated for respiratory distress and transported to PACU. CXR revealed a large right pleural effusion. After two stable hours on IMV patient desaturated to 41%. Manual ventilation proved difficult breath sounds were diminished bilaterally and suction catheter failed to traverse the tube. Following a third intubation endotracheal tube examination revealed a distal secretion-blood concretion with near complete Murphy's eye occlusion. Thoracentesis removed 2L. Sunday, October 13 8:00 AM - 9:30 AM FA MC303 Accelerated Idioventricular Rhythm (AIVR) and Hemodynamic Instability in a Blunt Trauma Patient Undergoing Femur Fracture Repair Vimal Desai, M.D., Charles Smith, M.D., Michael Howkins, D.O., Nathaniel Bolli, M.D., Case Western Reserve University MetroHealth Medical Center, Cleveland, OH A 20-year-old man sustained a high speed MVC. During transport he had multiple PVCs. ECG showed sinus tachycardia but was otherwise normal. He was scheduled for femur fracture repair. Shortly after rapid sequence induction he developed a wide complex accelerated idioventricular rhythm (AIVR). Whenever heart rate fell below 95-100 the same AIVR would ensue. Administration of glycopyrolate maintained ST with hemodynamic stability. Postoperatively there were frequent PVCs and AIVR. Echocardiography and cardiac MRI revealed mild global LV dysfunction and focal RV dysfunction consistent with myocardial contusion. Troponins were negative. Outcome was favorable without syncope chest pain or heart failure.

B.S., Alberto De-Armendi, M.D., M.B.A., University of Oklahoma, Oklahoma City, OK A 12-year-old obese patient with an acquired anterior mediastinal mass and a difficult airway causing tracheal obstruction was scheduled for a supraclavicular biopsy. Our anesthesia team devised a sequentially algorithmic plan of action to manage any encountered complications allowing us to escalate the invasiveness of care in a stepwise fashion to counter any impediments in securing an airway. Our team resorted to MAC sedation leading to a comfortable patient and a successful operation. We opted to avoid general anesthesia to side step potential difficult intubation difficulties as well as decrease the risk of post procedural nausea and aspiration. Sunday, October 13 8:00 AM - 9:30 AM PD MC312 Fiberscope Access To Larynx And Trachea Via A Supraglottic Device In An MPS1 Child With A Difficult Airway David Beebe, M.D., University of Minnesota Medical School, Minneapolis, MN, Kumar Belani, M.B. B.S., Amplatz Children's Hospital, Minneapolis, MN This challenging case describes a 5-year-old with advanced MPS1H disease requiring anesthesia for multiple procedures. During a previous attempt he could not be intubated by an anesthesiologist for tonsillectomy and adenoidectomy. We used sevoflurane for induction and i.v. placement and while the patient was breathing spontaneously continued anesthesia with propofol infusion during which time an AirQ® LMA was placed. A pediatric fiberscope was preloaded with an endotracheal tube and successfully introduced into the trachea via the supraglottic airway that allowed continued spontaneous breathing. The child was then successfully intubated. The procedures were completed and the child was successfully extubated.

She presented for re-operationof limb fixation and muscle flap with contralateral fibular bone harvesting. Intraoperatively an epidural catheter was placed for postoperative pain management. Seven hours into the surgery an acute arterial thrombosis occurred during vascular anastomosis of the muscle flap requiring emergent anticoagulation with heparin. Postoperatively the heparin infusion was discontinued and enoxaparin (1 mg/kg every 12 Copyright © 2013 American Society of Anesthesiologists hours) initiated. The epidural catheter was removed uneventfully on POD#5 after the enoxaparin had been held for a 24-hour period Sunday, October 13 8:00 AM - 9:30 AM PD MC314 Anesthetic Management in Patient With Marfans Syndrome Diffcult Airway Full Stomach With Significant Right Sided Spontaneous Pneumothorax Angelina Bhandari, M.D., Javier Joglar, M.D., Driscoll's Children Hospital/ UTMB, Corpus Christi, TX A 17-year-old cachetic male with hx of Marfan syndrome severe asthma Mitral Valve prolapse aortic root dilatation pectus carinatum who presents to the ER with sudden onset of chest pain. CXR reveals 90% Right sided spontaneous pneumothorax. The patient had short TM distance about 4 cm and NPO status was NOT met prior to arriving to the OR. He was also on a partial rebreather. The surgeon requested strongly to do be done under GA. Mask anestheisa instituted and spontaneous ventilation maintained. Addition of IV ketamine also used. First attempt revealed a grade 4 view. Sunday, October 13 8:00 AM - 9:30 AM PD MC315 Cardiac Toxicity Associated With Bupivacaine Penile Blockade in an Infant Richard Blum, M.D., Charles Nargozian, M.D., Alfonso Casta, M.D., Sharon Redd, M.D., David Waisel, M.D., Boston Children's Hospital, Boston, MA A former premature six-month-old presented for circumcision. Following inhalation induction and planned spontaneous mask ventilation the urology team placed a penile block using with 1 ml/kg of 0.25% bupivacaine. Within 1-2 minutes the patient's HR and BP dropped to 90's and 40's/20's. Spontaneous ventilation ceased while ECG demonstrated ST-T wave abnormalities and wide complex sinus rhythm. Controlled ventilation was started and a weak femoral pulse led to 4 minutes of chest compressions. 1.5 ml/kg of 20% intralipid was administered over about 90 seconds with a prompt return of stable vital signs and improvement in ECG changes. Sunday, October 13 8:00 AM - 9:30 AM PD MC316 Anesthesia for a Combative Child With DiGeorge Syndrome and Autism Requiring Sedation for Frequent Immunoglobulin Infusion Kadia Bundu, Shridevi Pandya Shah, M.D., UMDNJ-NJMS, Newark, NJ A case of a nine-year-old boy with severe nonverbal autism and 22Q11.2 microdeletion syndrome. Due to panhypogammaglobulinemia and recurrent sinopulmonary infection he receives immunoglobulin infusion therapy every three months with each session lasting six hours under sedation. He has verbal apraxia sensory disintegration and seizure disorder. He requires premedication and sedation due to high anxiety and severe combative behavior.

Lisa Caplan, Emad Mossad, M.D., Texas Children's Hospital, Houston, TX A 10-month-old with a ventricular septal defect required anesthesia for surgical repair. As per our institutional practice only infants less than one month of age routinely receive irradiated and cytomegalovirus (CMV) negative packed red blood cells for the cardiopulmonary bypass (CPB) prime. After median sternotomy was performed the thymus was absent in a patient who had no pre surgical genetics testing. Due to the concern for graft versus host disease the entire cardiopulmonary bypass circuit required repriming with CMV negative irradiated blood. The CMA which was sent intraoperatively did confirm a 22q11 deletion several days later. Sunday, October 13 8:00 AM - 9:30 AM PD MC318 Anesthetic Challenges in a 7-Year-Old Boy With Prader-Willi Syndrome Who Presented for Eye Muscle Surgery Daniel Carinci, M.D., NYU Langone Medical Center, New York, NY 7-year-old boy with Prader-Willi syndrome (BMI of 39) presented for eye muscle surgery. He was admitted the night prior; noisy breathing episodes of apnea and desaturation to upper 80s were noted. After mask induction patient desaturated to low 80s requiring two-man technique to maintain adequate ventilation. Glidescope revealed a grade 2 view and an ETT was secured. After extubation patient with airway obstruction and saturations as low as 80% requiring nasal trumpet and chin lift. On arrival to PACU patient lethargic with SpO2s remaining around 90%.

He initially presented to the primary physician with dyspnea and was given albuterol without improvement. Subsequently he presented to the ER and CT scan showed a mediastinal mass compressing the trachea. A diagnostic axillary node biopsy was planned. The need to keep the airway patent precluded general anesthesia. The decision was made to use sedation with ketamine and distraction in combination with local anesthetic cream and infiltration. The patient tolerated the procedure well while maintaining spontaneous ventilation. Sunday, October 13 8:00 AM - 9:30 AM PD MC321 A Case of Anaphylactic Shock to Albumin During T2-L2 Spinal Fusion in a Prone Pediatric Patient Maggie Chou, M.D., Columbia University New York Presbyterian, New York, NY, Manon Hache, M.D., Morgan Stanley Children's Hospital of New York, New York, NY Anaphylaxis in a prone patient presents challenges for the anesthesiologist: diagnosis identifying the triggering agent and particularly medication administration and resuscitation. The most common triggering agents are antibiotics neuromuscular blockers and latex. There have been only a handful of reports of anaphylaxis to albumin and none in pediatric patients thus far. We describe the first reported case of anaphylaxis to albumin in a 15-year-old male patient undergoing T2-L2 spinal fusion and discuss the treatment options in a prone patient and the decision to halt or continue surgery. Sunday, October 13 8:00 AM - 9:30 AM PD MC322 Emergent Surgery in a Child With Diabetic Ketoacidosis Melissa Coleman, M.D., Sanjib Adhikary, M.D., Uma Parekh, M.D., Pennsylvania State University, Hershey, PA A 5-year-old girl weighing 27 kg with diabetic ketoacidosis was scheduled for emergent laparotomy after worsening abdominal pain increasing abdominal circumference persistent metabolic acidosis and portal gas on abdominal x-ray. Intravenous induction was done with fentanyl lidocaine propofol and rocuronium. Five minutes after intubation the patient decompensated into PEA and progressed to ventricular fibrillation. ACLS was initiated and the abdomen was simultaneously decompressed with a midline incision. Spontaneous circulation returned after approximately 40 minutes. The patient was transported to PICU for further stabilization before surgery. Propofol in an acidotic patient with abdominal compartment syndrome caused this adverse event.

It occurs from an inborn error of cholesterol biosynthesis. The congenital abnormalities that are associated with this syndrome provide difficulty in mask ventilation and intubation. This case presentation is a TE fistula repair in a 3-day-old newborn with Smith-Lemli-Opitz syndrome. The patient had microcephaly and micrognathia. The patient was intubated under general anesthesia with video laryngoscopy while the infant was spontaneously breathing. The endotracheal tube was right mainstemmed and then pulled back until bilateral breath sounds were auscultated. The patient was successfully ventilated. Sunday, October 13 8:00 AM - 9:30 AM PD MC334 Anesthetic Management of Pediatric Patients With Stuve Wiedemann Syndrome Odinakachukwu Ehie, M.D., Anita Patel, M.D., New York University Langone Medical Center, New York City, NY A 56-day-old infant male with Stuve Wiedemann syndrome and myoclonic seizures was scheduled for laparoscopic G-tube placement given his high risk of aspiration. He was born with a history of respiratory insufficiency requiring intubation at birth along with an echo that estimated PAS pressures around 30 mmHg (2/3 systolic pressure). He was subsequently weaned to FiO2 of 35% and extubated while managed with nitric oxide. Given the high risk of a difficult airway ENT performed a laryngoscopy pre-operatively to confirm no need for a tracheostomy. The patient then underwent a rapid sequence induction and was intubated with no intraoperative complications. Sunday, October 13 8:00 AM - 9:30 AM PD MC335 Anesthetic Management of Tracheoesophageal Fistula/Esophageal Atresia Repair Complicated by a Vascular Ring and Congenital Heart Disease Justin Farmer, M.D., Michael Sroka, M.D., Wake Forest, Winston Salem, NC We present a 3-day-old female born at 36 weeks gestation found to have a tracheoesophageal fistula with esophageal atresia after failure of orogastric tube placement. Additional workup revealed a right aortic arch patent ductus arteriosus and complete vascular ring. The patient was brought to the OR induced and intubated. Flexible bronchoscopy confirmed ETT placement and pericarinal TEF. A second intravenous line and arterial line were placed. Anesthetic maintenance was continued with sevoflurane and rocuronium. Surgery proceeded with vascular ring and TEF ligation in addition to gastrostomy tube. The patient was returned to the intensive care unit intubated. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 8:00 AM - 9:30 AM PD MC336 Focus on a Known Difficult Airway Results in Sevoflurane Exposure in an MH-Susceptible Patient Tanna Ferrara, D.O., Devika Singh, M.D., Ronald Litman, D.O., Children's Hospital of Philadelphia, Philadelphia, PA A 6-year-old female with difficult airway neuromuscular scoliosis thoracic insufficiency syndrome (nightly bipap 14/6 x 8) and known RYR-1 receptor mutation was scheduled for VEPTR expansion x 2. A primary and backup plan for intubation were readied in the OR. The room was set for MH precautions with activated charcoal filters in line with the inhalation and exhalation ventilator tubing but the tape and sign across the inhaled agents was missed by all members of the anesthesia team. We discuss the care of this patient post-op after inadvertent Sevoflurane exposure and the importance of safety checks in the OR. Sunday, October 13 8:00 AM - 9:30 AM PD MC338 Anesthetic Management of an Emergency Case for a Patient With Trisomy 7p: A Very Rare Genetic Abnormality. Melissa Flanigan, D.O., Eric Massey, M.D., Monica Ata, D.O., Kristen Dragan, M.D., West Virginia University, Morgantown, WV 14-year-old female presented to our facility with rapidly deteriorating respiratory status and abdominal compartment syndrome. Past medical history included a partial Trisomy 7p and all its sequelae and an unspecified psychotic disorder. A very brief preoperative exam showed a nonverbal patient with no obvious airway abnormality and no cardiac issues. Emergently she was taken to the operating room for an exploratory laparotomy emphasizing her multiple abdominal issues. A basic anesthetic plan along with intravenous resuscitation was initiated with adjustments for her rare abnormality. Sunday, October 13 8:00 AM - 9:30 AM PD MC339 Anesthetic Management of Pediatric Patients With Trifunctional Protein Deficiency Stephen Flynn, M.D., Tara Wenger, M.D., Can Ficicioglu, M.D., Ronald Litman, D.O., The Children's Hospital of Philadelphia, Philadelphia, PA Trifunctional protein (TFP) is responsible for metabolism of long chain fatty acids (FA). During fasting or stress buildup of FA in muscle of TFP deficient patients can result in detergent-like reactions inducing rhabdomyolysis. Although mechanisms for rhabdomyolysis in TFP deficiency are different than more common perioperative forms of rhabdomyolysis (e.g. muscular dystrophies) many anesthesiologists avoid volatile anesthetics and succinylcholine for fear of causing rhabdomyolysis. We report three TFP deficient children receiving multiple anesthetics. CK levels prior to and following anesthetics(total n=26)were charted and analyzed to determine if there existed any association between CK level and TIVA vs. volatile general anesthesia. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 8:00 AM - 9:30 AM PD MC340 Anisocoria in a Four Month Old Child Under General Anesthesia Daniel Ford, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA, Thomas Chalifoux, M.D., University of Pittsburgh School of Medicine, Pittsburgh, PA The appearance of anisocoria in the perioperative period is alarming as it may represent serious neurologic pathology. Although this finding is rare particularly in the pediatric population the anesthesiologist should be able to recognize anisocoria understand the etiology and potential differential diagnoses and begin an appropriate evaluation. Balancing the priorities of the anesthetic operative procedure and workup of unexpected anisocoria can be challenging. We report a case of anisocoria in a four-month-old child under general anesthesia for an elective inguinal hernia repair and review our approach to this diagnostic dilemma. Sunday, October 13 8:00 AM - 9:30 AM PD MC341 Congenital Lipomatosis: A Rare Condition Contributing to a Challenging Pediatric Airway Anne Savarese, M.D., Jessica Galey, M.D., University of Maryland School of Medicine, Baltimore, MD We present a 3-year-old boy with congenital lipomatosis and a large facial tumor presenting for radical resection and reconstruction. He had significant right sided facial swelling enlargement of the right hemimandible maxilla zygoma as well as tonsil parotid and submandibular glands. The contours of his mouth were distorted and his trachea was significantly deviated. We secured his airway while maintaining spontaneous ventilation using nasal fiberoptic bronchoscopy assisted with a video fiberoptic laryngoscope to obtain a clear view of the glottis. The surgery proceeded uneventfully he was extubated in the OR and discharged home on POD 3. Sunday, October 13 8:00 AM - 9:30 AM NA MC342 Intraoperative Cerebral Vascular Accident During Spinal Surgery Carlos Garcia, M.D., Dimiter Arnaudov, M.D., LAC+USC Medical Center, Los Angeles, CA This case involves a 64-year-old male who presented to the operating room for anterior cervical decompression and fusion for unstable cervical spine. After a smooth induction he was intubated using a pediatric fiberoptic bronchoscope. He was place in mayfield pins and cervical traction. During the dissection of the neck the patient lost somatosensory and motor evoked potentials on the right side of his body. The procedure was cancelled and the patient was taken to MRI which was initially negative. Repeat MRI showed an internal capsule infarct. He had complete right sided hemiplegia and hyperalgesia resulting from the infarct. Sunday, October 13 8:00 AM - 9:30 AM NA MC343 Anesthetic Implications of a Carotid Body Tumor Resection Mauricio Garcia Jacques, M.D., Robina Matyal, M.D., Feroze Mahmood, M.D., BIDMC, Boston, MA 43-year-old F who presented recurrent episodes of loss of balance and shaking with associated slurred speech and confusion. She only recalled the shaking and loss of balance as presenting symptoms. The patient was found to have bilateral carotid body tumors left larger than right. Her laboratory work up Copyright © 2013 American Society of Anesthesiologists was negative for carcinoid or pheochromocytoma. Imaging revealed highly vascularized masses from C2C4 around the internal carotid. Balloon occlusion test developed delayed areas of left sided brain ischemia. After tumor embolization she underwent successful excision of the left sided mass sparing the internal carotid and the laryngeal nerves. Sunday, October 13 8:00 AM - 9:30 AM NA MC344 Emergent Craniotomy in a Pregnant Patient With Rapidly Rising Intracranial Pressure Danielle Gluck, M.D., Irene Osborne, M.D., Mt. Sinai Hospital, New York, NY A 37-year-old female with no PMH P3013 at 22 weeks gestation presented with 2 weeks of worsening headaches emesis lethargy with left upper extremity weakness and photophobia. On exam patient had slurred speech left homonymous hemianopsia left hemiparesis and hemisensory neglect. MRI showed a large partially cystic mass in right temperoparietal region with midline shift uncal herniation and right mid brain compression. After discussion with patient OB-GYN neurosurgery and anesthesia decision was made to proceed with right temporal craniotomy and tumor resection. This patient poses concerns including management of pregnant patient for emergent non-obstetric surgery with increasing intracranial pressure. Sunday, October 13 8:00 AM - 9:30 AM NA MC345 Anesthetic Considerations for a Patient With an Implanted Neurostimulator Device Stephen Goldberg, M.D., Tara Kennedy, M.D., Thomas Jefferson Univerity Hospital, Philadelphia, PA A paucity of information exists in the literature regarding the intraoperative management of deep brain stimulators. A number of special concerns for implanted neurostimulators exist specifically the risk for interference with routinely used devices such as electrocardiography electrocautery cardiac pacemakers and external defibrillators and MRI. We will discuss the perioperative management used to face these challenges in two cases; a 57-year-old male with DBS placed for essential tremors that underwent Right bronchoscopy and video assisted thoracic surgery and a 78-year-old female with DBS placed for refractory Parkinson's disease who underwent open repair of a nasal fracture. Sunday, October 13 8:00 AM - 9:30 AM NA MC346 Use of Ketamine as an Induction Agent in Craniotomy for Traumatic Brain Injury Michelle Gonta, M.D., Corey Scher, M.D., NYU School of Medicine/Bellevue Hospital Center, New York, NY 20-year-old healthy female s/p multiple stab wounds to the torso and head taken emergently to operating room for craniotomy and exploration of stab wound to skull and washout and closure of stab wounds to torso. Prior to induction patient was noted to be somewhat hypotensive with SBP 80s-90s and decision was made to use ketamine for induction to improve hemodynamics. Rapid sequence intubation performed without difficulty. BP following induction was 101/72. ICP remained stable intraoperatively both by neurosurgeon's visual assessment and ICP monitoring. Discussion will focus on newer studies showing benefits of using ketamine in traumatic brain injury.

Sunday, October 13 8:00 AM - 9:30 AM NA MC351 The Anesthetic Concerns of Cervical Vagal Schwannomas Grace Huang, M.D., Mount Sinai, New York, NY Schwannomas can occur anywhere in the body and between 25-45% of reported cases arise in the head and neck. Schwannomas can arise from various origins. Cervical vagal schwannomas are rare parapharyngeal neoplasms that are included in a differential diagnosis that is important to understand because of the varied pathophysiological consequences. Surgical manipulation of vagal schwannomas can cause severe bradycardia and in some cases asystole. Furthermore resection of this tumor can result in deficits such as vocal cord palsy. Thus it is important to review the implications of this subset of head and neck masses. Sunday, October 13 8:00 AM - 9:30 AM NA MC352 Intraoperative Diagnosis and Management of Dapsone Induced Methemoglobinemia in a Patient Undergoing Intraoperative MRI Guided Craniotomy for Tumor Matthew Hulse, M.D., Athir Morad, M.D., J.P. Ouanes, M.D., Johns Hopkins Hospital, Baltimore, MD A 32-year-old female presented for craniotomy to resect recurrent glioblastoma multiformans (GBM). During the patient's preoperative chemotherapy treatment she was placed on PCP prophylaxis with diamino-diphenyl sulfone (Dapsone). On the day of surgery physical examination findings revealed cyanosis of the patient's digits but were attributed to preexisting Raynaud's disease. Pulse oximetry intermittently revealed saturations >90%. After induction of general anesthesia pulse oximetry more consistently registered saturations at 85%. An arterial blood sample demonstrated a methemoglobin concentration of 16.7%. The methemoglobenemia was treated with 1mg/kg of 1% methylene blue and serial arterial blood samples confirmed resolution of the episode.

Her past medical history was also significant for hypertension dyslipidemia hypothyroidism and fibromyalgia. She had presented with multiple episodes of neurologic deficits in her life time compatible with cerebral infarctions. She was planned for a revascularization surgery including left superficial temporal artery to left middle cerebral artery bypass. Perioperative risk factors affecting morbidity of this particular condition and anesthetic management to decrease these risks are going to be discussed in this case report. Sunday, October 13 8:00 AM - 9:30 AM NA MC354 66-year-old Female With Deep Brain Stimulator Presenting for Electroconvulsive Therapy Yashar Ilkhchoui, M.D., Eli Torgeson, M.D., University of New Mexico, Albuquerque, NM We report the case of a 66-year-old woman with past medical history of major depressive disorer diabetes mellitus type 2 end-stage kidney disease kidney transplant essential tremor for which she underwent a deep brain stimulator (DBS) a year ago. She presented with worsening depression with catatonic features and was elected for electroconvulsive therapy (ECT). Her deep brain stimulator was turned off a week prior to ECT to avoid any potential interference between ECT electrical impulse and DBS electrodes. For ECT sessions general anethesia was induced with methohexital and succinylcholine and entire procedure and recovery were uneventful. Sunday, October 13 8:00 AM - 9:30 AM NA MC355 Anesthetic Management for Human Spinal Cord Schwann Cell Transplantation Craig Jabaley, M.D., Thomas Fuhrman, M.D., Jackson Memorial Hospital/University of Miami, Miami, FL Herein we describe the anesthetic management for the first enrollee in a Phase 1 clinical trial of autologous Schwann cell transplantation following acute thoracic spinal cord injury. A motionless surgical field is required during intramedullary injection which necessitates prolonged apnea. Following endotracheal intubation maintenance of general anesthesia with intravenous versus volatile agents demonstrated a minor improvement in PaO2. CPAP was used to facilitate apneic oxygenation with a concomitant linear increase in PaCO2 which the patient tolerated well. Our experience reaffirms the minimal impact of volatile agents on hypoxic pulmonary vasoconstriction and highlights the modern utility of apneic oxygenation.

She is found to have Posterior Reversible Encephalopathy Syndrome (PRES) and after delivery she is started on anticonvulsant and Copyright © 2013 American Society of Anesthesiologists antihypertensive therapy with complete resolution of her neurological symptoms. PRES is characterized by bilateral symmetrical vasogenic edema in the posterior parietal lobes identifiable on MRI. If diagnosed early patients can have a full recovery and avoid complications such as permanent neurologic impairment or death. Sunday, October 13 8:00 AM - 9:30 AM NA MC360 Prolonged Wakeup Caused by Pneumocephalus Following Resection of Craniopharyngioma Lorraine Kerchum, Stanlies D'Souza, M.D., Baystate Medical Center, Springfield, MA Two years after resection of a large craniopharyngioma compressing the optic chiasm with resultant panhypopituitarism a 66-year-old male developed new visual symptoms. Imaging revealed tumor recurrence with several cystic outpouchings the largest being 3cm causing significant pressure upwards into the hypothalamic area. He subsequently underwent a left pterional craniotomy and resection of recurrent craniopharyngioma using sevoflurane and remifentanil anesthesia. The case was complicated by internal carotid artery rupture but no significant blood loss resulted. Upon cessation of general anesthesia he was unable to follow commands and experienced significant right-sided weakness. Reimaging showed pneumocephalus causing a left-to-right 6mm midline shift. MCC Session Number – MCC06 Sunday, October 13 10:30 AM - 12:00 PM CA MC361 Liver Transplantation in a Patient With Significant Pulmonary Hypertension Hovig Chitilian, M.D., Worasak Keeyapaj, M.D., Jonathan Charnin, M.D., Massachusetts General Hospital, Boston, MA Liver transplantation (LTx) in patients with mean pulmonary artery pressure (mPAP) >35mmHg is associated with significant mortality. We report a case of successful LTx in a patient with a mPAP of 40mmHg. He had been managed on sildenafil and epoprostenol. Intraoperative pulmonary hypertension was treated with escalating doses of epoprostenol (to 13ng/kg/min) as well as inhale nitric oxide. Right ventricular (RV) function was monitored with TEE. Following reperfusion the mPAP increased to 50mmHg but responded to diuresis and inotropic support. His postoperative course was characterized by persistent pulmonary hypertension. He was ultimately weaned off epoprostenol and maintained on sildenafil. Sunday, October 13 10:30 AM - 12:00 PM CA MC362 Management of New Hemodynamically Significant Bundle Branch Block During Open ThoracoAbdominal Aortic Aneurysm Repair Yi Jia Chu, M.D., Pema Dorje, M.D., Univ of Michigan, Ann Arbor, MI During a thoracoabdominal aortic aneurysm repair using distal perfusion a peculiar intermittent hemodynamic change was noted. Bypass was achieved via a large bore cannula in the right IJ with its tip at the superior atrial-caval junction per TEE. During the later half of the case bundle branch pattern with prominent venous pulsation associated with a decrease in arterial pressure was noted. No ST changes or Copyright © 2013 American Society of Anesthesiologists no wall motion abnormalities were noted. We hypothesize the cannula tip irritated the SA node and the internodal conduction pathways leading to premature atrial contraction and resultant hemodynamics. Sunday, October 13 10:30 AM - 12:00 PM CA MC363 Active Automatic Cardioverter-Defibrillator During Laser Transurethral Resection of the Prostate Bryan Cohen, M.D., Armin Deroee, M.D., Jerome O'Hara, M.D., Cleveland Clinic, Cleveland, OH Two patients each with an implanted cardioverter defibrillator device underwent a laser vaporization of the prostate without deactivation of the device. Both surgeries proceeded without complication and on follow up no unnecessary defibrilator firing had occurred in the postoperative period. Based on the technology involved in green light laser prostate surgery no interference with the device should be expected. Although more studies are needed it is reasonable to believe that due to lack of interference between laser surgery and implantible cardioverter defibrillators these devices need not be deactivated prior to certain laser procedures. Sunday, October 13 10:30 AM - 12:00 PM CA MC364 Perioperative Management of Patient With Gastropericardial Fistula Matthew Culling, M.D., Lev Deriy, M.D., Kathleen Reyes, M.D., University of New Mexico, Albuquerque, NM A 70-year-old female with history of 3 vessel CABG and Nissen fundoplication presented to the emergency department with chest pain and shortness of breath. An ECG demonstrated diffuse T-wave abnormalities and atrial fibrillation with RVR. A CT with contrast revealed a pneumopericardium and a communication between the gastric fundus and pericardium. She underwent a gastropericardial fistula repair under general anesthesia with invasive monitoring and central venous access. Her post-op course was complicated by infection and she was discharged on POD #35. Sunday, October 13 10:30 AM - 12:00 PM CA MC365 Acute Bronchospasm Following Adenosine Administration in the Cardiac Catheterization Lab: A Case Report Nicholas Davis, M.D., Maya Jalbout-Hastie, M.D., New York Presbyterian Hospital-Columbia University, New York, NY Patient is a 65-year-old woman with a history of SVT and mild adult-onset exercise-induced asthma who presented to the cardiac catheterization lab for radio frequency ablation. Immediately following administration of adenosine the ventilator indicated elevated peak pressures and end tidal CO2 tracing was lost.

B.S., Alfonso Casta, M.D., Shoaib Mohammad, M.D., Boston Children's Hospital, Boston, MA We present a 13-year-old male with HCC extending to the IVC and right atrium who underwent complete hepatectomy with ex-vivo dissection and re-transplantation of the malignancy-free liver on cardiopulmonary bypass. Despite normal coagulation studies severe portal hypertension contributed to uncontrollable blood loss after incision. Due to the rapid blood loss estimated as high as 1.5L/min the patient was placed on cardiopulmonary bypass to facilitate the procedure. The patient required massive transfusion Factor VII and vasoactive infusions to maintain adequate blood volume and perfusion. He was stabilized transferred to the ICU for ongoing resuscitation and discharged neurologically intact POD 20. Sunday, October 13 10:30 AM - 12:00 PM CA MC367 Diagnosis of Tetralogy of Fallot in an Adult Patient by Transesophageal Echocardiography and Anesthetic Management of the Surgical Repair Michael Dutt, M.D., New York University Medical Center, New York, NY A 55-year-old female presented with several months of general fatigue and exertional dyspnea and preoperative transthoracic echocardiogram findings of severe aortic stenosis and regurgitation. She was scheduled for aortic valve replacement but pre-cardiopulmonary bypass transesophageal echocardiogram (TEE) revealed a previously undiagnosed Tetralogy of Fallot. She underwent successful surgical repair at a later date. Anesthetic management was guided by intraoperative TEE to ensure careful control of hemodynamics. Post-operative EKGs revealed widening of her QRS complex and occasional ventricular ectopy. Electrophysiology study showed no inducible ventricular arrhythmias and the patient was discharged home on post-operative day 13. Sunday, October 13 10:30 AM - 12:00 PM CA MC368 Bivalirudin Anticoagulation in a Patient With Heparin Antibodies and Renal Failure During Transition From ECMO to LVAD Guy Efune, M.D., Philip Greilich, M.D., UT Southwestern Medical Center Dallas, Dallas, TX Patients with heparin antibodies and renal failure requiring anticoagulation for cardiac bypass present a distinct challenge in anesthetic management. We present the case of a 67-year-old male patient who experienced an MI and subsequently developed heparin antibodies and renal failure. The patient was subsequently placed on ECMO after suffering a cardiac arrest during an attempted placement of an Impella device. Bivalirudin anticoagulation was successfully used during his transition from ECMO to LVAD. Intraoperative CRRT was performed to assist in removal of residual Bivalirudin at the completion of his procedure. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM CA MC369 The Anesthetic Considerations and Management in Patients With Autoimmune Hemolytic Anemia Undergoing Aortic Valve Replacement Carol Eisenstat, M.D., Frank Seifert, M.D., Thomas Bilfinger, M.D., Igor Izrailtyan, M.D., SUNY Stony Brook University Hospital, Stony Brook, NY Autoimmune hemolytic anemia (AIHA) a condition where warm or cold-reactive autoantibodies are directed against antigens located on the surface of erythrocytes poses a significant anesthetic challenge in the management of such patients undergoing cardiac surgery involving cardiopulmonary bypass (CPB). Formation of the antibody-antigen complex in AIHA along with inherent destabilization of the erythrocyte membrane from CPB results in severe hemolysis. Thorough assessment and coordination between medical surgical perfusion and anesthesia teams are essential for optimal outcomes. We present two cases of AIHA in patients undergoing successful aortic valve replacement and compare perioperative considerations in patients with warm- and cold-reactive AIHA. Sunday, October 13 10:30 AM - 12:00 PM CA MC370 Acute Myocardial Infarction and Cardiac Tamponade Following Left Pneumonectomy Enrique Escobar, M.D., Shahla Escobar, M.D., Chen Shi, M.D., Lisa Morse, M.D., University of Texas Southwestern Medical Center, Dallas, TX A 71-year-old male patient with a left lung adenocarcinoma presented to the hospital for a left pneumonectomy. On emergence from anesthesia the patient developed severe hypotension with STsegment elevation in the inferolateral leads. The patient was emergently transported to the cardiac catherization suite where the cardiologists deployed a bare metal stent in the right coronary artery and gave a loading dose of eptifibatide. A transesophageal echocardiogram at that time demonstrated a significant pericardial effusion. The patient was taken back to the operating room where the surgeons performed a median sternotomy to successfully repair a hole in the left atrium. Sunday, October 13 10:30 AM - 12:00 PM CA MC371 Monitored Anesthesia Care in Cardiac Ablation Therapy for Recurrent Ventricular Tachycardia in a Patient With Obstructive Sleep Apnea Karen Fleming, M.D., Amanda Burden, M.D., Erin Pukenas, M.D., Keyur Trivedi, M.D., John Andriulli, M.D., Cooper University Hospital, Camden, NJ A 77-year-old male with a history of obstructive sleep apnea CAD and ischemic heart disease presented with rapid sustained ventricular tachycardia (VT) and hypotension with multiple shocks from his ICD. Medical management with PO amioderone was unsuccessful. Intra-operative ablation was planned under monitored anesthesia care (MAC) using a Propofol infusion. This infusion resulted in hypotension and hypoxemia which were both treated. During the procedure the patient had two episodes of sustained ventricular tachycardia that required external shock at 300J. Successful ablation occurred after stabilization of vital signs. The patient remained on PO amioderone and was discharged to rehab.

Pre-induction arterial line was placed under ultrasound guidance. After induction two large-bore peripheral intravenous lines were placed for fluid and medical management during the case as there was concern that subclavian and internal jugular access would interfere with the artificial heart. Pre-operative TEE evaluation was also not possible with the artificial heart. After sterile prep and drape the cardiac surgeons placed a femoral introducer and pulmonary artery catheter which was floated after the cadaveric heart was transplanted. Sunday, October 13 10:30 AM - 12:00 PM CA MC373 Anesthetic Considerations for a Patient With a Large Invasive Mediastinal Mass Undergoing Sternotomy and Tumor Debulking Surgery Jeffrey Fujii, M.D., Galina Dimitrova, M.D., The Ohio State University, Columbus, OH The patient is a young male with no significant past medical history diagnosed with an anterior mediastinal tumor that invades the superior vena cava right atrium and right ventricle and has significant metastases to both lungs. Thoracic surgery performed a median sternotomy with partial debulking of the mediastinal and pulmonary tumor burden. Planning the successful anesthetic was a collaborative effort between anesthesia surgery and perfusion. The patient was given a general anesthetic with alternating left and right lung ventilation arterial blood pressure monitoring femoral central venous access transesophageal echocardiography standby massive transfusion capability and an epidural for postoperative pain control. Sunday, October 13 10:30 AM - 12:00 PM CA MC374 General Anesthesia in a Patient With Bullous Pemphigoid Lauren Ganderson, M.D., Baylor College of Medicine, Houston, TX A 39-year-old male with active bullous pemphigoid presented with a pericardial effusion necessitating an urgent pericardial window. Bullous pemphigoid an autoimmune mediated subepidermal blistering disease causes bullae on the trunk extremities oropharynx and esophagus. His skin was protected from development of bullae by coating the endotracheal tube and arterial and central lines secured with sutures in petroleum jelly with no complications. His eyes were covered with low adhesive paper tape but skin erosions on the eyelids did develop. He was stable throughout the procedure on a norepinephrine infusion which was weaned with emergence and he was extubated in stable condition. Sunday, October 13 10:30 AM - 12:00 PM CA MC375 Aortic Arch Thrombus Emergent Urgent or Elective Resection? Mauricio Garcia Jacques, Robina Matyal, M.D., BIDMC, Boston, MA 64-year-old female recently taken off systemic anticoagulation for history of lower extremity ischemia who presents with left upper extremity pallor and loss of peripheral pulses. Duplex of the affected Copyright © 2013 American Society of Anesthesiologists extremity demonstrated thrombosis in her mid ulnar and distal radial arteries. Given her poor response to heparin infusion she was taken for emergent thrombectomy. We performed a general anesthetic to do a TEE evaluation. Two mobile echogenic densities were found in the distal aortic arch the larger measuring 2x1 cm. These findings raised the question of how to proceed? Is this an urgent emergent or elective aortic arch thrombectomy. Sunday, October 13 10:30 AM - 12:00 PM CA MC376 Intraoperative Fire Following Unrecognized Pulmonary Injury During Redo-Sternotomy Stephen Gleich, M.D., Jonathan Fox, M.D., Mayo Clinic, Rochester, MN A 72-year-old male with prior history of aortic valve replacement underwent redo-sternotomy and aortic valve re-replacement for bioprosthetic aortic regurgitation. After induction and sternal split a large circuit leak occurred. Because no gross air leak was observed in the surgical field an equipment malfunction was the presumed cause and FiO2 and fresh gas flows were increased. While troubleshooting cautery use ignited a surgical sponge in the superior chest which was quickly extinguished. Closer inspection revealed a 2 cm round area of pulmonary injury which was oversewn. No gross tissue injury was evident and the case proceeded uneventfully. Sunday, October 13 10:30 AM - 12:00 PM CA MC377 Gathering the Missing Pieces of a Challenging Puzzle Wendy Bernstein, M.D., Nicholas Goehner, University of Maryland, Baltimore, MD Resection of an atrial myxoma should prevent embolic phenomenon not cause it. We present a 59-yearold female with increasing dyspnea and stroke with a left atrial myxoma. After induction intubation and invasive line placement sternotomy was completed. During venous cannulation SBP acutely decreased to 38mm Hg. TEE revealed obstruction of the LV inflow tract by the myxoma. Successful cannulation was achieved despite large hemodynamic fluctuations. Separation from cardiopulmonary bypass was complicated by biventricular akinesis which could have been attributed to embolization of friable tumor down the coronary arteries. Sunday, October 13 10:30 AM - 12:00 PM CA MC378 Sometimes You Don't Want to be in the Right Andrew Goldberg, M.D., Ralph Dilisio, M.D., Menachem Weiner, M.D., Gregory Fischer, M.D., Ichan School of Medicine at Mount Sinai, New York, NY Our patient had a history of surgically corrected L-type transposition of the great vessels and ventriculoseptal defect (VSD) now presenting for left ventricular assist device (LVAD) placement. The patient required an LVAD secondary to right ventricle (systemic ventricle) failure from chronic strain. Also his three previous pacemakers were no longer enough to help his cardiac output. After difficult line placement secondary to multiple previous cardiac surgeries the case progressed uneventfully. Once the LVAD was placed and activated the previously corrected VSD re-opened from the newly created pressure gradient. The patient required significant hemodynamic support for the rest of the case. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM CA MC379 Anticoagulation for Urgent CABG Procedure in a Patient With Hx of HIT Leonid Gorelik, M.D., Ping Wang, M.D., Ryan Colapietro, D.O., University of Cincinnati Medical Center, Cincinnati, OH 75-year-old male with a history of heparin induced thrombocytopenia (HIT) CAD and DMII transferred from outside hospital for urgent CABG. Reportedly developed HIT 10 years ago when hospitalized for sepsis as confirmed by family. This case illustrates anticoagulation with Bivalirudin instead of the standard heparin protocol used for on-pump CABG. We discuss the diagnosis and future implications of developing HIT alternatives for anticoagulation during CPB as well as the titration and monitoring of Bivalirudin. In this case the intra-op coarse was complicated by significant bleeding multiple transfusions of products and the administration of factor VII. Sunday, October 13 10:30 AM - 12:00 PM CA MC380 Transcatheter Aortic Valve Implant in an Orthotopic Heart Transplant Recipient Via the Subclavian Artery Sheena Gormley, M.D., Peter McGuigan, M.B. B.Ch., Adesh Ramesewak, M.B. B.Ch., Andrew McKinley, M.D., Ganesh Manoharan, M.D., Mark Spence, M.D., Royal Victoria Hospital Belfast, Belfast, United Kingdom Symptomatic aortic stenosis has a mortality of 40% at one year. Transcatheter Aortic Valve Implantation (TAVI) offers a therapeutic alternative for those patients who are deemed high risk for surgery. There have been three reported cases in the literature of TAVI being carried out in orthotopic heart transplant recipients using either a trans-apical or femoral approach. We present the fourth case of TAVI in an orthotopic heart transplant recipient and the first to be carried out via a subclavian approach. We discuss the evidence for TAVI and the role of the anaesthetist in the multidisciplinary management of the patient. Sunday, October 13 10:30 AM - 12:00 PM CA MC381 Anesthetic Management for Bentall Procedure in a Patient With History of Malignant Hyperthermia Kevin Graham, D.O., Shvetank Agarwal, M.B. B.S., Vijay Patel, M.D., Manuel Castresana, M.D., Georgia Regents University, Augusta, GA 65-year-old-female with a large ascending aortic aneurysm and severe aortic regurgitation was scheduled for a Bentall procedure. Her history was significant for an episode of malignant hyperthermia (MH) during a previous anesthetic. Perioperative anesthetic management included meticulous preparation of anesthetic machine avoidance of triggering anesthetic agents and continued monitoring in the postoperative period. In view of the prolonged cardiopulmonary bypass time of approximately 5 hours patient was rewarmed to a core temperature of 36.5C to avoid worsening of coagulopathy while closely monitoring for early signs of MH. The patient remained free from MH through her ICU and hospital stay. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM CA MC382 Crashing on Bypass With Two Peripheral IVs: The Benefit of Immediate and Continuous Chest Compressions on Neurologic Outcome After Cardiac Arrest at Induction for Emergent CABG Mary Graham, Mike Hosking, M.D., University of Tennessee Medical Center, Knoxville, TN 58-year-old female with critical coronary disease in stable condition after cardiac catheterization acutely decompensated in the preoperative holding area prior to central line placement for urgent CABG. She was immediately taken to the OR where cardiac arrest occured at induction followed by immediate and continuous cardiac massage and ACLS protocol which allowed time to crash onto cardiopulmonary bypass within 30 minutes. Postoperatively the pt was extubated in 48 hours without sustaining any anoxic insult and was discharged 9 days later. Early and continuous cardiac massage may have been a key factor contributing to favorable neurologic outcome. Sunday, October 13 10:30 AM - 12:00 PM CA MC383 Clinical Implication of Pulmonary Flow Assessment Affected by Single Lung Ventilation in Minimally Invasive Cardiac Surgery Radhika Grandhe, M.D., Shiva Sale, M.D., Cleveland Clinic, Cleveland, OH 59-year-female underwent robotic excision of left atrial myxoma. Anesthetic management included double lumen ETT invasive lines and TEE. Intraop TEE showed LA mass attached to interatrial septum situated close to the RPV. The mass was excised via left atriotomy and LA closed after complete deairing. While weaning off bypass with left lung ventilation TEE showed normal pulmonic vein inflow on color doppler interrogation. Post CPB and chest closure double lung ventilation was resumed and TEE revealed RUPV flow acceleration. The incision was reopened and a repair stitch along RUPV was removed which normalized flow on TEE. Sunday, October 13 10:30 AM - 12:00 PM CC MC384 A Balancing Act: Managing Ischemic Stroke in the Setting of Ventricular Pseudoaneurysm Hannah Keirnes Lovejoy, M.D., Donald Crabtree, M.D., Roy Neeley, M.D., Vanderbilt University, Nashville, TN 56-year-old F with h/o familial hyperlipidemia CAD with multiple MI's (most recent 2 wk prior) and aortic stenosis s/p apicoaortic bypass who presented with R sided weakness and expressive aphasia. Pt was diagnosed with L MCA infarct treated with clot retrieval complicated by hemorrhagic conversion. An echo revealed a density in the apicoaortic conduit. Subsequent cardiac MRI showed contained rupture and pseudoaneurysm formation of the cardiac apex. Fibrinous material flowed between the rupture and apex during diastole. Her course was further complicated by HIT. ICU management goals included reduction of cardiac workload maintenance of CPP and anticoagulation.

She was started on oral baclofen prior to pump extraction. Intraoperative course was uneventful with successful extubation in the operating room. However she developed sudden respiratory distress in the Post Anesthesia Recovery Unit. Her emergent reintubation was complicated by generalized rigidity and difficulty in opening the mouth despite adequate dosing of muscle relaxant secondary to acute baclofen withdrawal. She underwent a tracheostomy on post-operative day 5 due to inability to wean. Sunday, October 13 10:30 AM - 12:00 PM CC MC386 Broken Heart Syndrome in a Patient With Myelofibrosis After Splenectomy: A Case Report Eugene Kim, M.D., Peter Roffey, M.D., Duraiya Thangathurai, M.D., University of Southern California, Los Angeles, CA A 65-year-old male with myelofibrosis and massive splenomegaly presented for splenectomy. His cardiac history was unremarkable and a preoperative echocardiogram was normal. His intraoperative course was unremarkable and the patient was extubated in the operating room and transferred to the ICU. The patient continued to have an uneventful recovery in the ICU and was subsequently transferred to the ward. On postoperative day 4 the patient was readmitted to ICU with atrial fibrillation with rapid ventricular rate to 170s beats per minute. Transthoracic echocardiogram demonstrated wall motion abnormalities with retained contractility of basal segment and akinesis of distal segments and apex. Sunday, October 13 10:30 AM - 12:00 PM CC MC387 Acute Kidney Injury and Ischemic Hepatitis Due to Huge Hematoma After Catheteriztion of Subclavian Vein Jae-Young Kwon, Eunsoo Kim, M.D., Jeong-Min Hong, M.D., Yun-Hee Han, M.D., Pusan National University Hospital, Busan A 74-year-old male presenting left leg pain and numbness underwent thrombectomy of superficaial femoral artery. Central vein catheter was inserted through the subclavian vein under general anesthesia. Catheterization and thrombectomy were performed without any problems. Heparin was administered during intraoperative and postoperative period. On second postoperative day He had syncope due to hemorragic shock. Chest computed tomography showed a large hematoma between pectoralis major and minor muscle on left chest wall. He developed acute kidney injury and ischemic hepatitis. He had contiunous renal replacement therapy and mechanical ventilation. He was transferred to general ward on the 19th ICU day. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM CC MC388 Challenges in the Medical Management of Multiple Different Intracranial Pathologies Martin Krause, M.D., Navaz Karanjia, M.D., Brian Lemkuil, M.D., University of California San Diego, San Diego, CA A 34-year-old developmentally delayed male presented with a right periorbital abscess pansinusitis and sepsis. Initial management included broad-spectrum antibiotics and surgical debridement of sinuses/orbit. Subsequent mental status deterioration led to neuroimaging that revealed: 1) abscesses involving the right frontal lobe adjacent to the ethmoid sinus and a second involving the hypothalamus optic chasm and anterior cerebral arteries; 2) anterior cerebral artery mycotic aneurysm; 3) noncommunicating hydrocephalus; 4) ischemic strokes to the corpus callosum and left pons. Laboratory evaluation revealed hyponatremia (126) and coagulopathy (INR 1.9) of unknown etiology. He was transferred to Neurocritical Care for medical management/surgical optimization. Sunday, October 13 10:30 AM - 12:00 PM CC MC389 Case of Neuroleptic Malignant Syndrome Secondary to Haloperidol and Quetiapine: Experience With Bromocriptine Therapy Jonathan Kremer, M.D., Jonathan Ratcliff, M.D., Betty Tsuei, M.D., Christopher Droege, Pharm.D, University of Cincinnati, Cincinnati, OH 68-year-old male with significant narcotic and benzodiazepine use admitted to the ICU with respiratory failure after cervical spine fixation. Haloperidol and quetiapine were used for the treatment of ICU delirium. A 107 F fever with severe autonomic instability developed on post operative day 5. Bromocriptine therapy was successfully initiated with symptomatic improvement and following two days of treatment dose taper was initiated. However he developed recurrent autonomic dysfunction without fever. Increased bromocripitine dose for an additional ten days followed by a week long taper resulted in complete resolution of symptoms. Sunday, October 13 10:30 AM - 12:00 PM CC MC390 Recurrent Cardiac Arrests Associated With Sepsis Complicating Prosthetic Valve Replacement Vikas Kumar, Shalin Shah, Sanjay Dwarakanath, Manuel Castresana, Georgia Regents University, Augusta, GA 49-year-old female with PMH of HTN ESRD hepatitis C spina bifida decubitus ulcer underwent bioprosthetic aortic valve replacement for aortic stenosis and extubated on day of surgery. On postoperative day two she developed sudden bradycardia cardiac arrest with successful resuscitation and had severe hypoglycemia and sepsis. TTE showed mild aortic regurgitation and mild perivalvular leak. Later patient was extubated but had similar episode of bradycardia leading to cardiac arrest with successful resuscitation on post-operative day eighteen. TEE showed worsening aortic regurgitation perivalvular leak and aortic annular abscess not diagnosed earlier on TTE. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM CC MC391 Unrecognized Sepsis in a Patient Undergoing Elective Coronary Artery Bypass Graft Surgery Vikas Kumar, Shalin Shah, Mary Arthur, M.D., Manuel Castresana, Georgia Regents University, Augusta, GA 77-year-old female with PMH of hypertension OSA multi-vessel CAD presented to ER with unstable angina and scheduled for CABG next morning. Despite being somnolent and temperature of 39.8 C on morning of surgery decision was made to proceed. Intraoperatively she was difficult to wean off bypass requiring inotropic vasopressors balloon pump and developed abdomen distension. Post-operative course was complicated by severe cardiogenic and septic shock with E. coli from blood culture multiorgan failure and severe acidosis despite aggressive antibiotics therapy and hemodynamic support. Her condition continued to deteriorate and went into cardiac arrest;and died on post-operative day four. Sunday, October 13 10:30 AM - 12:00 PM CC MC392 A Rare Cause for Dyspnea: Acute Fibrinous and Organizing Pneumonia Catherine Kuza, M.D., Theofilos Matheos, M.D., Stephen Heard, M.D., University of Massachusetts Medical School, Worcester, MA A 60-year-old male smoker presented with worsening dyspnea and hemoptysis. Chest x-ray and CT scan showed bilateral diffuse opacities and ground glass densities respectively. Bronchoscopy was negative for malignancy granulomas and bacteria. Open lung biopsy revealed acute fibrinous and organizing pneumonia (AFOP). AFOP is a rare disease that is idiopathic or occurs due to environmental exposures infections or collagen vascular diseases. Patients present with dyspnea cough fever or acute respiratory distress syndrome. Definite diagnosis requires an open lung biopsy. Treatment includes antibiotics corticosteroids and cyclophosphamide with varying responses. The optimal duration of therapy is unknown. Sunday, October 13 10:30 AM - 12:00 PM CC MC393 Postoperative Central Venous Catheter Migration Detected by Abnormal Central Venous Pressure Tracing Karim Ladha, Cheryl Bline, M.D., Joseph Hyder, M.D., Ph.D., Massachusetts General Hospital, Boston, MA The patient was a 58-year-old man with a history of hypertension who underwent an open AAA repair. The procedure was preceded by an uneventful placement of a left internal jugular triple-lumen catheter confirmed to be in the left innominate vein by chest x-ray in the OR. He was transferred post-operatively to the ICU still intubated. Approximately four hours after arrival to the ICU CVP tracing began displaying intermittent pulsatilty correlated to the respiratory cycle during mechanical ventilation. A chest film was obtained and showed that the tip had straightened 90 degrees and migrated into the left superior intercostal vein.

During the procedure patient suddenly became hypotensive with a significant drop of ETCO2. CPR proceeded with SBP maintained above 70mmHg throught the chest compression. TEE showed dilated RA and RV and a normal LVF. A clinical diagnosis of PE was made. A total of 4mg of tPA was administered directly to the pulmonary artery through the PA cath.Shortly after the patient's hemodynamics dramatically improved and stabilized. Patient had a full recovery. Sunday, October 13 10:30 AM - 12:00 PM CC MC395 Management of Patient With Ruptured Intracerebral Aneurysm With Concurrent Abdominal Aortic Aneurysm Shea Stoops, M.D., Ben Chen, M.D., Abhijit Lele, M.D., University of Kansas Medical Center, Kansas City, KS A 66-year-old Caucasian man with a history of COPD CAD MI CVA smoking and DVT presented with a Hunt and Hess 1 Modified Fisher Grade 1 subarachnoid hemorrhage due to ruptured 6 mm bilobed anterior cerebral artery aneurysm. He also had a 7 cm infra renal aortic aneurysm that required repair. Patient underwent successful endovascular repair of cerebral aneurysm on post-bleed day 1 and endovascular aortic aneurysm repair (EVAR) on post-bleed day 2. The patient was discharged on post bleed day 9 without evidence of vasospasm or hydrocephalus and absence of focal neuro deficit. Sunday, October 13 10:30 AM - 12:00 PM CC MC396 Perioperative Management of a Previously Undiagnosed Giant Pericardial Effusion Marcos Lopez, Patrick Henson, D.O., Michael Pilla, M.D., Vanderbilt University School of Medicine, Nashville, TN A 56-year-old M with PMH COPD L BKA s/p multiple failed thrombectomies and a-fib was transferred from an OSH with concern of R leg ischemia. Emergency thrombectomy vs. bypass was scheduled. Postinduction TEE showed a large pericardial effusion. He underwent axillary-femoral bypass and was transferred to the CVICU post-op. He began to show tamponade physiology so underwent pericardiocentesis at the bedside with acute drainage of 1 L of bloody fluid and additional 2L over 2 days. This complex case lends to a detailed discussion of clinical decision making for pericardial effusion and tamponade in the perioperative period. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM CC MC397 Successful Fibrinolitic Therapy for Massive Pulmonary Embolism in Immediate Postoperative Period: Is it Really an Absolute Contraindication? Jack Louro, M.D., Roman Dudaryk, M.D., UM/ Jackson Memorial Hospital, Miami, FL We will be presenting the case of a 48-year-old morbidly obese female with multiple medical problems admitted with Fournier's gangrene that experienced cardiovascular collapse leading to cardiac arrest postoperatively in the ICU. We will review the differential for her decompensation and diagnostic modalities available to the critical care physician. We will discuss the diagnosis and treatment of massive pulmonary embolism in a patient with hemodynamic instability and open surgical wounds. Emphasis will be placed on the use of TEE as a primary diagnostic modality and the use of IV thrombolytics in the postoperative period. Sunday, October 13 10:30 AM - 12:00 PM CC MC398 Mixed Cardiogenic and Septic Shock From Suppurative Pancarditis Ayumi Maeda, M.D., Massachusetts General Hospital, Boston, MA, Hayley B. Gershengorn, M.D., Beth Israel Medical Center, New York, NY A 53-year-old cirrhotic male presented with chest pain and fever. EKG showed diffuse ST-elevations and initial transthoracic echocardiography revealed global hypokinesis. He was diagnosed with MSSA aortic valve endocarditis and shock which persisted despite antibiotics. Repeat TTE showed massive pericardial effusion with tamponade. Emergent pericardiocentesis drained purulent discharge (700ml); sanguineous pleural fluid was also drained from the left--both grew MSSA. His course was complicated by acute kidney injury requiring hemodialysis respiratory failure requiring mechanical ventilation disseminated intravascular coagulation and death. This case demonstrates that aortic valve endocarditis can cause suppurative pancarditis and thoracic empyema with mixed cardiogenic and septic shock. Sunday, October 13 10:30 AM - 12:00 PM CC MC399 Anesthetic Management of a Parturient With Congenital Complete AV Block for Elective C-Section. Sandeep Mayur, M.D., Kalpana Tyagaraj, M.D., Maimonides Medical Center, Brooklyn, NY A 20-year-old pregnant female G1P0 at 39 weeks gestation with history of congenital complete heart block presented for elective C-Section. Preop. cardiac consult was obtained. Preoperative vital signs were BP 104/75 HR 52 SpO2 100% and the patient showed no signs of heart failure on physical exam. EKG showed third degree AV block. Echocardiogram revealed ejection fraction of 60% with no significant valvular disease normal chamber sizes. A-line and external pacing pads were placed. Atropine 0.2 mg was given prophylactically. C-Section was performed uneventfully under CSE anesthesia. Patient was monitored in CICU for 48 hours before discharge.

His daily baseline hydromorphone usage was 60mg intravenous morphine equivalent. General anesthesia was performed and maintained with Ketamine Propofol and Isoflurance. Naloxone was administered incrementally maintaining hymodynamic and thermodynamic stability. Patient was extubated on postoperative day (POD) one in the Intensive Care Unit (ICU) on an infusion of Ketamine-Fentanyl-Midazolam and Dexmedetomidine. Adjunct medications were added as needed. Opioid requirement peaked at 143% above baseline on POD two and returned to baseline by POD six upon hospital discharge. Sunday, October 13 10:30 AM - 12:00 PM CC MC402 Patient Safety Lessons From a Tracheostomy Emergency Linda-Jayne Mottram, M.B. B.Ch., Lynn Cromie, M.B. B.Ch., Michael McGinlay, M.B. B.Ch., South Eastern Health and Social Care Trust, Belfast, United Kingdom We describe the sequence of events which ensued following the urgent exchange of a surgical tracheostomy in one of our intensive care patients. Loss of end-tidal carbon dioxide surgical emphysema and failure to adequately ventilate the patient resulted in a cardiorespiratory arrest. Despite initially hypothesising that an upper airway false passage had been created it became apparent that lower airway trauma had occurred and a left sided bronchopleural fistula was present. We postulate the mechanism of such an injury and share the patient safety lessons we have learned about tracheostomy management in our institution.

Uneventful induction and intubation. In the middle of a case surgeon requested to give antithymocyte globulin. Half hour later patient became hypertensive and tachycardic despite adequate anesthesia and analgesia which was controlled with labetalol. Solumedrol given. Patient extubated at end of case. After extubation patient developed severe hypertension tachyacrdia and desaturated to mid 80's. HeHeheCXR showed pulmonary edema with hypercarbia on ABG. Patient reintubated. Hypoxia and hypertension thought to be secondary to cytokine release syndrome secondary to administration of antithymocyte globulin. Sunday, October 13 10:30 AM - 12:00 PM CC MC404 Pulmonary Artery Rupture in a Patient With Orthotopic Heart Transplant After Total Artificial Heart Placement Koichi Nomoto, M.D., Adam Evans, M.D., MBA, Mount Sinai Medical Center, New York, NY A patient s/p orthotopic heart transplant involving an explanted total artificial heart (TAH) was brought to the ICU with a pulmonary artery catheter which was removed on POD#4. On POD#5 he was extubated but refused to take anything orally. A Nasogastric tube was placed and associated with coughing. This was complicated by increased chest tube output and need for emergent intubation. A TEE revealed cardiac tamponade. He underwent emergent re-exploration where bleeding was found from the left PA distal to the transplant anastomosis. Our case illustrates that a patient can still have a PA rupture despite TAH and replacement. Sunday, October 13 10:30 AM - 12:00 PM CC MC405 ECMO Failure in Severe Idiopathic Giant Cell Interstitial Pneumonia and Pulmonary Hypertension William O'Byrne, M.D., Robert Atiken, M.D., University of Alabama School of Medicine, Birmingham, AL The patient is a 64-year-old female with past medical history significant for rheumatoid arthritis and polymyalgia rheumatica. She was diagnosed with giant cell interstitial pneumonia via VATS and admitted to the MICU at the University of Alabama Hospital. She was treated aggressively with open lung ventilation steroids and antibiotics. She underwent right and left heart catheterization which showed pulmonary arterial hypertension and no coronary disease. She was subsequently placed on veno-venous ECMO via the right internal jugular approach as a bridge to lung transplantation. However the patient could not be effectively oxygenated despite 100% FiO2 for seven days.

Uterine rupture is defined as a disruption of the uterine myometrium with extrusion of membranes and fetal parts into the peritoneum. There is usually associated bleeding and abdominal pain. Despite an expedient diagnosis and early surgical intervention morbidityand mortality is high. This is a concern for all the providers involved including anesthesiologists obstetricians surgeons and neonatologists. Fortunately the vital communication and coordination between the multiple teams involved in this case resulted in favorable outcomes for both mother and neonate. Sunday, October 13 10:30 AM - 12:00 PM OB MC407 Anesthetic Management for Labor and Delivery of a Patient With Severe Cystic Fibrosis Ravpreet Gill, M.D., Jaya Ramanathan, M.D., University of Tennessee Health Science Center, Memphis, TN A 20-year-old G1P0 with history of cystic fibrosis presented in labor at 36.4 weeks gestation. Past medical history was also significant for cholestasis and respiratory insufficiency requiring intubation 2 months earlier. Meds: Albuterol pancrealipase tobramycin VS: Temp 36.6 C HR 114 RR 18 BP 103/72 SpO2 95% on room air. Airway: Mallampati 2. Lungs: decreased air entry b/l with diffuse wheezing. An early labor epidural was placed humidified oxygen was delivered and continous pulse oximetery was used. The patient also received regularly scheduled albuterol nebulizer treatments. The second stage of labor was assisted and vaginal delivery was uneventful. Sunday, October 13 10:30 AM - 12:00 PM OB MC408 Anesthetic Management of a Parturient With Complex Regional Pain Syndrome: A Case Report and Review of Literature Ramon Go, Tricia Desvarieux, M.D., Marianne David, M.D., Sean Malin, M.D., George Washington University Hospital, Washington, DC The patient is a 38-year old G1P0 parturient who presents at 383 weeks gestation age for elective cesarean section with a history of CRPS. The patient has had 11 sympathetic blockades and stopped taking gabapentin during the pregnancy. A combined spinal epidural (CSE) is opted to provide rapid dense block for c-section, for management of potential CRPS symptoms, and post-op incisional pain. Her intraoperative course is unremarkable. She received a patient controlled epidural anesthesia infusion of bupivacaine 0.0325% with fentanyl for post-operative pain control. The catheter was discontinued 24 hours after delivery.

An epidural catheter was placed without complication. The patient subsequently complained of constant sharp bilateral subscapular back pain with radiation to her left shoulder and arm that was incapacitating. She was unable to lye supine or in the lateral decubitus position. Gross neurological exam was unremarkable. Electrocardiogram revealed sinus tachycardia with no ischemic changes; chest roentgenogram was within normal limits. The epidural catheter was replaced yet she remained acutely symptomatic. An emergency cesarean section was considered in order to expedite treatment for her potentially life threatening condition. Sunday, October 13 10:30 AM - 12:00 PM OB MC410 Anesthetic Management of Cesarian Delivery for a Patient With Symptomatic Obstructive Goiter Brian Gregson, M.D., Caleb Zelenietz, M.D., University of Manitoba, Winnipeg, MB A 33-year-old female presented with an increasingly symptomatic goiter in the second trimester of pregnancy. The patient was a recent immigrant with a long-standing goiter and a previously attempted thyroidectomy in her home country which was cancelled because of failed intubation. She had become stridorous at rest and had worsening exertional dyspnea but no positional symptoms. Endocrinology optimized her medical therapy and Head & Neck Surgery deferred thyroidectomy until the postpartum period. We elected to avoid natural labour and instead use epidural anesthesia for cesarian delivery in a controlled setting. The child was successfully delivered without adverse outcome. Sunday, October 13 10:30 AM - 12:00 PM OB MC411 Management of Ceasarean Section in a Patient With Placenta Previa and Accreta and Strong Family History of Malignant Hyperthermia Shaun Gruenbaum, M.D., Jacob Baranoski, B.Sc., Alice Li, B.Sc., Benjamin Gruenbaum, M.D., Alan Weinstock, M.D., Yale University School of Medicine, New Haven, CT A 38-year-old G3P2 female with prior cesarean section x 2 strong family history of malignant hyperthermia known posterior placenta previa and suspected placenta accreta was admitted at 33+3 weeks with spontaneous rupture of membranes. During cesarean section with hysterectomy patient was maintained on 60% N2O in 40% O2 intermittent propofol boluses with sufentail 1 mcg/kg/hr and midazolam 2 mcg/kg/hr. The procedure was complicated by 7L blood loss resuscitated with 5L crystalloid 10u PRBC's 7u FFP and 10u platelets. The patient remained hemodynamically stable and normothermic throughout the case and was extubated within 1 hour of transport to SICU.

She required a temporary transvenous pacer and was admitted to our in situ L&D ICU for telemetry ICU for telemetry. She received epidural analgesia for her labor that was augmented with Pitocin. The epidural was bolused to achieve anesthesia and a forceps delivery was performed to shorten the 2nd stage of labor. A permanent pacemaker was implanted prior to her discharge. We will discuss the management of bradycardia and anesthetic implications of transvenous pacing and neuraxial anesthesia in our presentation. Sunday, October 13 10:30 AM - 12:00 PM OB MC413 A Case of Sheehan Syndrome: Pituitary Hemorrhage and Cerebral Vasospasm Resulting From Covert Severe PostPartum Hemorrhage Fatimah Habib, M.D., Cooper University Hospital, Camden, NJ A 39-year-old female at 38 weeks gestation presented with eclampsia and developed occult postpartum intra-abdominal hemorrhage following a cesarean section. Following emergent exploratory laparotomy her condition continued to deteriorate and she began displaying varied neurological deficits with evidence of PRES syndrome on imaging. Further imaging revealed a hemorrhagic pituitary gland and cerebral vasospasm. She was diagnosed with Sheehan syndrome. Treatment with Nimodipine was begun to alleviate the cerebral vasospasm. This case demonstrates an example of Sheehan syndrome PRES syndrome the minimal treatment options for cerebral vasospasm and pituitary hemorrhage following severe postpartum hemorrhage and the utility of Nimodipine. Sunday, October 13 10:30 AM - 12:00 PM OB MC414 Unusual Cause of Postpartum Headache Mona Halim-Armanios, M.D., Ohio State University Medical Center, Columbus, OH A rare cause of Post-Partum Headache: Another reason for earlier imaging: Differential diagnosis of a post-partum headache includes a wide variety of medical conditions. The diagnosis could be compounded by the likely possibility of post-dural puncture headache. We present a rare cause of postpartum headache in a patient who has received labor epidural analgesia.She developed left hemiparesis & global -aphasia. A diagnosis of Call-Fleming Syndrome or Reversible Cerebral vasoconstriction Syndrome was based on her presentation and imaging. This case demonstrates a rare cause of postpartum headache that has not been published in the anesthesia literature before. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM OB MC415 Pulmonary Embolism During Emergent Cesarean Section in a Patient With Preeclampsia and Twin Gestation Sabrina Haque, M.D., MBA, Jeremy Grayson, M.D., UMDNJ Robert Wood Johnson, New Brunswick, NJ A 38-year-old G2P0 at 36 weeks with twin gestation presented for induction of labor for severe preeclampsia. The patient required general anesthesia for delivery of Twin B secondary to cord prolapse. During uterine closure end tidal carbon dioxide (etCO2) oxygen saturation and blood pressure decreased precipitously. Vasopressors were administered to maintain SBP 120-140. ABG at this time revealed pH 7.27 pCO2 49 paO2 175 on FiO2 100%. Within minutes etCO2 oxygen saturation and blood pressure normalized with supportive treatment. Postoperatively a CT angiogram of the chest indicated pulmonary embolus in the right main and segmental pulmonary arterial branches. Sunday, October 13 10:30 AM - 12:00 PM OB MC416 Anesthetic Considerations for Obstetric Patients With Spinal Muscular Atrophy Frederick Isaacson, D.O., Heather Nixon, M.D., University of Illinois Chicago, Chicago, IL Spinal muscular atrophy (SMA) is a rare degenerative disease that affects the anterior horn cells of the spinal cord. We present a medically challenging case of a 39-year-old multiparous patient with spinal muscular atrophy type III who presented for repeat elective cesarean delivery that was complicated by postpartum hemorrhage due to profound atony necessitating conversion from neuraxial blockade to general anesthesia. The patient's course was further complicated by prolonged weaning from mechanical ventilation due to residual muscle weakness and the development of disseminated intravascular coagulopathy. This case highlights the anesthetic considerations for obstetric patients with SMA. Sunday, October 13 10:30 AM - 12:00 PM OB MC417 Neurofibromatosis in the Parturient Patient: A Case Report and Review Andrea Johnson, D.O., Alice Tsao, M.D., Riverside County Regional Medical Center, Moreno Valley, CA 29-year-old 37 week parturient laboring patient requested an epidural for 10/10 labor pain. PMHx was significant for neurofibromatosis 1 Brown-Sequard Syndrome and Chronic Pain Syndrome. Neurosurgery evaluation revealed stable neurological deficits since 2007 with no pre-gravid MRI changes. PSHx consisted of C2-C7 neurofibroma resection in 2007 posterior C2-C7 spinal fusion in 2009 and multiple neurofibroma excisions. PE found limited cervical ROM narrow incisor gap and Mallampati 4. Epidural catheter placement was deemed safe anesthetic plan however MRI to r/o new neurofibromas was not possible due to precipitous labor. We propose lumbar ultrasound as an alternative diagnostic tool. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM OB MC418 Neuraxial Analgesia in the Laboring Parturient With Arnold-Chiari Type I Malformation - Relief of Pain in Unchartered Terrain? Suneil Jolly, M.D., Ana Lobo, M.D., M.P.H., Yale New Haven Hospital, New Haven, CT A 17-year-old G1P0 @40w+2 diagnosed with Arnold-Chiari type 1 malformation during her first trimester presented in labor requesting pain relief. She was diagnosed via CT scan after experiencing headaches vision changes and dizziness; an MRI was unsuccessful secondary to anxiety with plans to follow-up postpartum. Upon assessment the patient was asymptomatic during the prior two weeks except for occasional numbness in two fingers bilaterally. After considering the limited data on ACT-1 with neuraxial analgesia and lack of recent symptoms an epidural was placed successfully with significant pain relief. The patient had NSVD without complications or exacerbation of symptoms. Sunday, October 13 10:30 AM - 12:00 PM OB MC419 Cerebrospinal - cutaneous Fistula in a Parturient Following Neuraxial Blockade Danny Joseph, Stanlies D'Souza, Baystate Medical Center, Springfield, MA A 26-year-old primigravida at 37 weeks with notable history of oxycodone abuse presented for a scheduled cesarean section. Intra-operative management included a single shot spinal combined with a lumbar epidural catheter. Postoperatively patient was noted to have an intrathecal-cutaneous fistula with persistent cerebrospinal fluid leak. This fistula was initially observed for the first two days postoperatively with no resolution. A neurosurgical consult was obtained and the decision was made to suture the fistula closed at the skin. The patient initially did not report any post dural puncture headache symptoms but at six month follow up reports chronic headaches. Sunday, October 13 10:30 AM - 12:00 PM OB MC420 Emergency Exploratory Laparotomy and C-Section in a 37-Week Parturient Who Was Pinned by an SUV Michael Jourden, Jennifer Eismon, Case Western Reserve University MetroHealth Medical Center, Cleveland, OH Trauma complicates 7% of pregnancies with fetal death occurring in 55% of major traumas. A 32-yearold 37-week pregnant previously healthy female presented after being hit by an SUV. At presentation she was hypotensive in the 60's with fetal heart rate in the 40's and was immediately taken for emergency c-section and exploratory laparotomy. Rapid sequence induction was performed and the patient was intubated using a glidescope. She remained intubated post-op and was taken to the SICU. She and baby are currently hospitalized (day #38). The mother is improving however the baby has suffered severe hypoxic encephalopathy. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM OB MC421 Anesthetic Management for Cesarean Section in a Paraplegic Parturient With Multiple Comorbidities Including Urosepsis and Pulmonary Embolus Sarah Kadhim, M.D., Lance Parks, D.O., West Virginia University, Morgantown, WV Pregnant patients with spinal cord injuries present unique anesthetic challenges. Several complications have been identified including autonomic hyperreflexia premature labor pressure sores urinary tract infections and failure to progress. The following case report describes a primigravid female with a history of thoracic spinal cord injury and intrapartum complications including urosepsis decubitus ulcer pulmonary embolus requiring treatment with heparin and increased narcotic tolerance. On induction of labor at 37 weeks gestation failure to progress necessitated anesthetic management for Cesarean section. The successful use of general anesthesia is described as well as special considerations for both general and regional anesthesia. Sunday, October 13 10:30 AM - 12:00 PM OB MC422 Management of a Parturient With Amyotrophic Lateral Sclerosis (ALS) Jerry Kalangara, M.D., Daria Moaveni, M.D., J. Sudharma Ranasinghe, M.D., University of Miami, Miami, FL A 34-year-old female who is 34 weeks pregnant was suffering from weakness of the upper and lower extremities due to ALS. She was requiring nasal cannula/ BiPAP to maintain adequate oxygen saturation. A multi-disciplinary team closely followed her. Due to her worsening condition the patient needed a cesarean delivery and all attempts were made to avoid intubation and the use of sedatives and hypnotics. Epidural anesthesia with ultrasound guidance was performed. An appropriate sensory level was achieved via careful titration of 2% lidocaine. A baby boy was delivered and the mother's respiratory symptoms improved significantly after delivery. Sunday, October 13 10:30 AM - 12:00 PM OB MC423 Challenge in the OB Suite: Handling Cardiac and Neurologic Issues in a Pediatric Primigravida Megha Karkera, M.D., University of Arkansas for Medical Sciences, Little Rock, AR This challenging case is a 16-year-old primigravida who was found to have severe long segment aortic stenosis during her pregnancy as well as multiple spinal lipomas during this time. Planning the anesthetic of this case required a significant amount of research and multi-disciplinary meetings/agreements. After considerable thought she was planned for an elective Cesarean Section under general anesthesia with placement of a preinduction arterial line as neuraxial anesthesia of any kind was considered unwise given her recent diagnosis of spinal lipomas. Sunday, October 13 10:30 AM - 12:00 PM OB MC424 ADAMTS13 Missense Mutant R1060W Presenting as TTP in Pregnancy Catriona Kelly, M.B.Ch.B., Conor McCarroll, M.B. B.Ch., Royal Hospital, Belfast, United Kingdom A 31-year-old primigravida presented at 33 weeks gestation with a rash and feeling generally unwell. She was anaemic Hb 38g/L and thrombocytopenic <10x 109/L. On examination the fetal heart was Copyright © 2013 American Society of Anesthesiologists absent and there had been no fetal movement for 12 hours. She was diagnosed with TTP and immediately transferred to tertiary care for plasma exchange and for obstetric management of the intrauterine death. When her platelets reached 20x 109/L labour was induced. Investigation revealed a R1060W mutation of the ADAMTS13 protein as the cause for her TTP which was precipitated by pregnancy. Sunday, October 13 10:30 AM - 12:00 PM OB MC425 Multidisciplinary Approach to Successful Craniotomy in Patient Presenting During the 3rd Trimester Bradley Kelsheimer, Jeffry Ostrander, Abhinava Madamangalam, University of Oklahoma, Oklahoma City, OK A 31-year-old female at 31 weeks gestation required a craniotomy for a recurrent ganglioglioma. We detail the planning process for her cranial surgery including positioning to optimize surgical exposure and left uterine tilt. Additionally she requested continuous perioperative and intraoperative fetal heart rate monitoring and an operative delivery for fetal deterioration during craniotomy. We will describe our multidisciplinary approach to achieving these goals including preparing for a Cesarean section during a craniotomy in the non L&D ORs at our institution as well as other contingency planning that was involved for a successful outcome for both mother and fetus. Sunday, October 13 10:30 AM - 12:00 PM OB MC426 Pelvic Peritoneal Block Stops Pain Nausea Vomiting and Retching During Cesarean Section Under Spinal Anesthesia Stephen Kennedy, M.D., Inova Fairfax Hospital, Falls Church, VA 30-year-old G2P1 female experienced pain nausea vomiting and retching during Cesarean Section under spinal anesthesia when the uterus was undergoing repair. Instillation of 20ml of 1% lidocaine onto the posterior wall of the uterus blocks the nerves traversing the peritoneum and immediately stops the reaction to uterine manipulation. Nerves traversing the peritoneum originate from the pelvic plexus and include parasympathetic nerves S2 3 4 as well as sympathetic nerves T10-L1. This represents a novel use for local anesthesia during an open surgical procedure to eliminate pain as well as reflex nausea vomiting and retching. Sunday, October 13 10:30 AM - 12:00 PM OB MC427 Pneumocephalus: Etiology of a Headache After Epidural Placement Firdous Khan, M.D., Crystal Wright, M.D., Baylor College of Medicine, Houston, TX This case describes a 34-year-old woman who developed a severe headache after attempted epidural placement for labor and delivery. Loss of resistance to air was the technique chosen for placement and the procedure was complicated with breech of dura. A head CT later diagnosed pneumocephalus. In the setting of a headache pneumocephalus-- although a severe complication--is often overlooked as opposed to the more well-known post puncture dural headache. Large volumes of air in the brain can cause serious neurologic complications and questions the advantage of using loss of resistance to air vs. saline in labor epidural placement. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM OB MC428 Anesthetic Management of Cervical Varices in a Parturient Janelle Kho, M.D., Barbara Scavone, M.D., University of Chicago, Chicago, IL A 39-year-old patient at 21 2/7 weeks gestation presented with vaginal bleeding and was found to have cervical varices. She experienced multiple bleeding episodes over several days (total EBL 2 liters) and presented for cervical compression sutures and possible hysterotomy/hysterectomy. Reports of this rare cause of bleeding are limited with obstetric management ranging from bed rest to emergent hysterectomy for massive hemorrhage (Yoshimura: J Ob Gyn Res 2004; 30:323). Anesthetic management has not been described; optimal practice remains unclear. Our anesthetic plan consisted of neuraxial anesthesia with general anesthesia held in reserve due to the unpredictable intraoperative course. Sunday, October 13 10:30 AM - 12:00 PM OB MC429 Ex Utero Intrapartum Treatment of Fetal Micrognathia Nicole King, M.D., Brandon DaValle, D.O., Erik Nagel, M.D., Sara Gonzalez, M.D., Naval Medical Center San Diego, San Diego, CA Ex Utero Intrapartum Treatment (EXIT) procedures have emerged as an option for potentially life-saving procedures in fetuses with predicted airway compromise at birth. A 26-year-old female presents with a 20 week ultrasound and imaging demonstrating severe fetal micrognathia glossoptosis polyhydramnios absence of a gastric bubble and suspected microtia. An EXIT procedure was completed with successful intrapartum endotracheal intubation with a flexible fiberoptic bronchoscope through a Laryngeal Mask Airway (LMA). This case represents the first EXIT procedure at Naval Medical Center San Diego and to our knowledge only the second EXIT procedure performed in the DOD Military Health System. Sunday, October 13 10:30 AM - 12:00 PM OB MC430 Anesthesia for C-Section in a Patient With Marfan Syndrome Complicated by Lumbar Tarlov Cyst John Kissko, M.D., Emily Baird, M.D., Ph.D., Richard Month, M.D., University of Pennsylvania, Philadelphia, PA A 41-year-old G2P1 presented at 38 weeks for elective Cesarean delivery. Her past medical history was significant for Marfan syndrome with dilated aortic root severe rheumatoid arthritis and multiple Tarlov and nerve root cysts from L2-S1. During this pregnancy she experienced new onset of numbness and paresthesias in her right lateral thigh. Surgical anesthesia was provided with a thoracic epidural placed at the T11/12 space and epidural 1.5% lidocaine with epinephrine 1:200 000 was administered (total volume 26mL maximum sensory level T3 bilaterally). Low-transverse Cesarean delivery was performed without neurologic cardiovascular obstetric or surgical complication. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 10:30 AM - 12:00 PM OB MC431 Anesthetic Management of a Rare Case of Cervical Pregnancy Presented With Vaginal Bleeding: Coordinated Team Work of the Anesthesiologist the Gynecologist and the Interventional Radiologist Ahmad Elsharydah, M.D., MBA, Maria Lasala, M.D., UT Southwestern Medical Center, Dallas, TX A 33-year-old F with cervical pregnancy (9 wks) admitted for vaginal bleeding. Treatments with intraamniotic injection of KCl and IM injection of Methotrexate failed. Patient's desire was to conserve uterus for future pregnancies therefore she was scheduled for D&C and possible hysterectomy. To minimize hemorrhage during D&C an interventional radiologist placed Fogarty balloons in the both iliac arteries. Balloons were inflated just before the surgery. She received 5 units PRBCs 2 units of FFPs and one unit of platelets in the OR and post-op ICU care. She recovered fully and was discharged few days later. Sunday, October 13 10:30 AM - 12:00 PM OB MC432 Anesthetic Management for Labor and Cesarean Section of a Parturient With Pseudotumor Cerebri and Substance Abuse Christina Lee, M.D., Patricia Dalby, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA A 33-year-old G10P5 with a history of chronic hypertension diabetes mellitus type 2 pseudotumor cerebri with prior VP and current LP shunts opioid abuse on Subutex asthma obesity hypothyroidism and anxiety was admitted at 38w2d gestation for induction of labor. After review of prior imaging showing the shunt catheter location an epidural was placed at L1-L2. She was taken for cesarean section for arrest of dilation and intolerance of labor but was unable to tolerate epidural anesthesia secondary to dyspnea. She underwent a general endotracheal anesthetic was extubated upon completion of surgery and had an uncomplicated postoperative course. MCC Session Number – MCC07 Sunday, October 13 1:00 PM - 2:30 PM PN MC433 Successful Treatment of Peripheral Neuropathic Pain With Duloxetine Following Neruoinvasive West Nile Virus Infection Ross Gliniecki, M.D., Ian Fowler, M.D., Lauren Mattingly, M.D., Naval Medical Center San Diego, San Diego, CA A 57-year-old female patient presented with severe burning extremity pain two weeks after diagnosis with neuroinvasive West Nile Virus infection. She had been treated with transdermal fentanyl for musculoskeletal pain but this was not effective for her presenting neuropathic symptoms. On evaluation she met DSM-IV criteria for Major Depressive Disorder and was treated with Duloxetine for both MDD and neuropathic pain. Significant improvement in neuropathic pain symptoms were observed by day 7 and Duloxetine was continued for 5 months until eventual resolution of pain and depressive symptoms. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM PN MC434 Perioperative Alpha-2 Agonist Adjunct Therapy for a Chronic Pain Patient Receiving Buprenorphine/Naloxone Brendan Griffis, D.O., John Capacchione, M.D., Matthew Hoch, D.O., Thomas Hayes, M.D., Walter Reed National Military Medical Center, Bethesda, MD A 25-year-old male with bilateral hip disarticulations who was taking buprenorphine/naloxone for chronic pain presented for heterotopic ossification excision of his sacrum and pelvis. He declined regional anesthesia and received general anesthesia with ketamine dilaudid and sevoflurane. Despite receiving large doses of opioids and a continuous ketamine infusion his pain remained 10/10 in the PACU. He was transferred to the ICU and started on a dexmedetomidine infusion in addition to the ketamine which reduced his pain to 5/10. This case illustrates the utility of alpha-2 agonist adjunct therapy for a chronic pain patient receiving opioid agonist/antagonists in the perioperative period. Sunday, October 13 1:00 PM - 2:30 PM PN MC435 A Novel Use of a Spinal Cord Stimulator in a Patient With Loin-Pain Hematuria Syndrome Samuel Grodofsky, M.D., Peter Yi, M.D., University of Pennsylvania, Philadelphia, PA Loin pain hematuria syndrome (LPHS) is a rare poorly understood diagnosis of exclusion characterized by flank pain and hematuria. We present a case of a 24-year-old woman with LPHS who presented to our clinic seeking minimally invasive intervention to reduce her pain and opioid requirements. She underwent a trial and then permanent implantation of spinal cord stimulator (SCS) with leads placed in paramedian position which brought relief and improved physical functioning. This is the first documented report of SCS for LPHS which is a much less invasive procedure than renal autotransplantation the most effective treatment described to date. Sunday, October 13 1:00 PM - 2:30 PM PN MC436 Severe Stevens-Johnson Syndrome; How Do I Control Your Pain? Jessica Hayes, M.D., Bruce Skolnik, M.D., Roy Soto, M.D., Beaumont Health Systems, Royal Oak, MI AF a 23-year-old male with a history of chronic back pain treated with six to ten Vicodin pills daily and prescribed marijuana presented to the Emergency Department with complaints of sore throat conjunctivitis and oral sores. He had recently started taking NSAIDs at home. His symptoms eventually progressed to severe Stevens-Johnson Syndrome necessitating hospitalization for management of severe pain and treatment to prevent infection and progression of this disease. His continuing epidermal and mucosal damage and baseline opiate tolerance necessitated pain service consultation with complex management of his pain including enteral mucosal topical and parenteral opiates and anticonvulsants. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM PN MC437 Altered Mental Status and Severe Hypotension in a Patient With Intrathecal Baclofen Pump Yashar Ilkhchoui, M.D., Eugene Koshkin, M.D., Brian Starr, M.D., Suzanne Numan, M.D., Ph.D., University of New Mexico School of Medicine, Albuquerque, NM A 53-year-old woman underwent an intrathecal baclofen pump placement to treat severe spasticity secondary to multiple sclerosis. 6 days after pump refill she developed severe hypotension and respiratory failure necessitating tracheal intubation and ICU admission. Her pump was interrogated and no error was noted. Her mental status and muscle tone improved after intrathecal medicine dose was reduced. She was extubated the day after but remained somnolent. The pump was emptied and it was noted that baclofen reservoir contained 6 ml less medicine than was programmed. Her intrathecal pump was replaced and her symptoms resolved in 24 hours. Sunday, October 13 1:00 PM - 2:30 PM PN MC438 A Case of Subdural Hematoma After Epidural Blood Patch in a Spontaneous Intracranial Hypotensive Patient With Multi-Level Cerebrospinal Fluid Leakage Young Joo, M.D., M.S., Kangwon National University Hospital, Chuncheon-Si Gangwon-Do, Republic of Korea A forty-two-year-old male presents to pain clinic with one-month history of spontaneous headache. The headache is postural and is refractory to conservative therapies and the radionuclide cisternography showed CSF leaks at T1 and L2 levels. An autologous interlamins epidural blood patches at L1-2 and T1-2 level under fluoroscopy has dramatically relieved symptoms. However he presents to ER 3days later with severe headache. The computed tomography revealed bilateral subdural hemorrhage (SDH). The patient underwent craniotomy to remove SDH. Subsequently headache has resolved completely and patient was discharged without any complication. Sunday, October 13 1:00 PM - 2:30 PM PN MC439 High Dose Lamotrigine for Chronic Post Stroke Pain Danny Joseph, Alfred McKee, Baystate Medical Center, Springfield, MA A 65-year-old male who had suffered a stroke presented with persistent chronic pain with residual right hemiparesis. With no relief with conservative and pharmacological therapy his chronic pain became debilitating to the point that he had attempted suicide. Subsequently he was started on lamotrigine which showed improvement of his central pain syndrome. The dose of lamotrigine was then titrated upwards until the pain had resolved reaching a dose of 700 mg per day. Sunday, October 13 1:00 PM - 2:30 PM PN MC440 Massive Intracranial Bleed After Intrathecal Pump Revision Enas Kandil, M.D., University of Texas Southwestern, Dallas, TX A 64-year-old male with Complex regional pain syndrome of left lower extremity underwent an Intrathecal pump revision. Past medical history included hypertension coronary artery disease obesity and depression. Medications included beta-blockers a diuretic gabapentin and duloxetine. Under Copyright © 2013 American Society of Anesthesiologists sedation utilizing fluoroscopic guidance while in the lateral position pump was revised with some difficulty placing the intrathecal catheter requiring multiple needle punctures to the Dura. Patient tolerated the procedure well and was admitted over night for observation. Over night patient became unresponsive was found to have suffered a massive intracranial bleed with a large midline shift on CT. Sunday, October 13 1:00 PM - 2:30 PM PN MC441 When Breathing is Affected: Pitfalls of Peripheral Nerve Catheters Michael Kaufmann, M.D., Ravi Singh, M.D., Tariq Malik, M.D., Dalia Elmofty, M.D., Magdalena Anitescu, M.D., University of Chicago, Chicago, IL A 52-year-old male with a history of CRPS underwent an ultrasound guided brachial plexus catheter placement for pain. The catheter was tunneled 2 in. posterior from the supraclavicular fossa. Patient had excellent pain relief for 3 weeks when he suddenly developed severe chest pain worse with inspiration. CT image was consistent with catheter migration close to pleura and attempts to remove it were unsuccessful. Further interventions under fluoroscopy guidance ensured removal of an intact but significantly stretched catheter with wire uncoiling. This case illustrates the pitfalls of wire reinforced peripheral nerves catheters and need for deeper tissues tunneling. Sunday, October 13 1:00 PM - 2:30 PM PN MC442 Severe Sciatica in a Parturient Patient Chang-Po Kuo, National Defense Medical Center/Tri-Service General Hospital Duke University Medical Center, Taipe; Billy Huh, Duke Universisty Medical Center, Durham, NC A 32-year-old parturient 21 weeks of gestation suffered from acute low back pain with radiculopathy. The MRI revealed disc protusion at L5/S1 with nerve root compression. Physical therapy and bed rest didn't provide much help. Her sleep was severely interupted. She could hardly walk or stand for a while. For the sake of the fetus the parturient refused any medication. After well explaination Enrac acupressure therapy was applied on her. The pain decreased and she regained normal activities again soon after the treatment. The life quality returned to her like before as she was not pregnant. Sunday, October 13 1:00 PM - 2:30 PM PN MC443 Successful Treatment of Refractory Complex Regional Pain Syndrome With Low-Dose Ketamine Infusion Jason Longwell, M.D., Terry Stambaugh, M.D., Walter Reed National Military Medical Center, Bethesda, MD A 30-year-old male with a one-year history of bilateral lower extremity Complex Regional Pain Syndrome (CRPS) refractory to multiple lumbar sympathetic blocks and to neuropathic pain agents (gabapentin pregabalin duloxetine) was admitted to the hospital for treatment with a low-dose ketamine infusion. The patient's symptoms resolved completely after 72 hours of ketamine infused at 20 mg/hr and he was discharged home. He did not require neuraxial or peripheral nerve blockade nor did he require admission to the intensive care unit. This case illustrates the successful treatment of CRPS without the potential complications associated with high-dose ketamine treatment. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM PN MC444 Epidural Blood Patch for Spontaneous CSF Leak in the Presence of Immune Mediated Thrombocytopenia: Between a Rock and a Hard Place. Ankit Maheshwari, M.D., Akhil Singh, M.D., Shrif Costandi, M.D., Cleveland Clinic, Cleveland, OH A 32-year-old female presented with complaints of orthostatic headache suggestive of intracranial hypotension. Imaging demonstrated cerebrospinal fluid leak at the lower thoracic level. Patient was a known case of immune mediated thrombocytopenia common variable immunodeficiency Sjogren's syndrome drug induced liver injury chronic steroid use and Diabetes. She also demonstrated persistent thrombocytopenia in spite of conventional treatment for immune mediated thrombocytopenia. We describe the considerations involved in planning an epidural blood patch in a patient with spontaneous CSF leak in the presence of active immune mediated thrombocytopenia. Sunday, October 13 1:00 PM - 2:30 PM PN MC445 Pemphigus Vulgaris Related Pain Apryl Martin, M.D., Azzam Alkhudari, M.D., John H. Stroger Jr Hospital of Cook County, Chicago, IL A paucity of data exists in the medical literature on pain treatment modalities for patients with pemphigus vulgaris. Pemphigus vulgaris is a chronic relapsing autoimmune blistering disease of the skin and mucous membranes that causes extreme pain. However it remains exceedingly rare and few studies describe the pain component of the disease and treatment outcomes. In patients such as ours with pemphigus pain that is diffuse nociceptive with coexisting neuropathic components pain management is complex. We utilized dual morphine therapies for basal and breakthrough pain gabapentin for nerverelated pain and continued disease modifying immunosuppressive therapy to provide optimal pain relief. Sunday, October 13 1:00 PM - 2:30 PM PN MC446 Ketamine Therapy for Opioid Induced Hyperalgesia in a Chronic Pain Pediatric Patient Mike Martinez, D.O., University of Missouri, Columbia, MO Chronic pain therapeutic modalities are constantly expanding; however our knowledge of Opioid Induced Hyperalgesia and its treatments are still very sparse. In this case report we will discuss the usage of Ketamine for OIH specifically because of its antagonism of the N-methyl-D-aspartate receptor. Obviating the activation of this ligand-gated calcium channel enables the prevention or interruption of the wind-up phenomenon which leads to central sensitization. Titrating Ketamine to effect over 6 days in the pediatric intensive care unit we were able to completely discontinue opioid therapy in a 15-yearold boy with chronic pain stemming from multiple abdominal surgeries.

Electrode migration is a significant complication in occipital nerve stimulation (ONS) partly because of the mobile anatomical location of electrode placement. We report a patient with occipital neuralgia who experienced loss of stimulation efficacy and muscle spasm during ONS therapy secondary to electrode migration which required three electrode revisions to achieve therapeutic benefit. We describe a method to revise electrode location without replacing the electrodes or accessing the generator using a Touhy placed along the desired trajectory though which the previously implanted electrode was passed. Sunday, October 13 1:00 PM - 2:30 PM PN MC448 The Naltrexone Conundrum: Perioperative Pain Management of the Patient on Naltrexone Brian Mirante, M.D., Keun Chung, M.D., Donna-Ann Thomas, M.D., Yale University School of Medicine, New Haven, CT 39-year-old F presents for robotic assisted radical hysterectomy. Patient in Naltrexone rehabilitation program for history of alcohol and heroin abuse. Presented for surgery after having never discontinued her Naltrexone. Neuroaxial and non-opioid technique planned but aborted after vasovagal event during attempted epidural placement. Surgery postponed and patient later presented off Naltrexone. Perioperative anesthetic pain management included Ketamine bolus and infusion Propofol infusion Ketorolac intravenous Acetaminophen. Post-operatively patient complained of mild-to-moderate pain effectively supplemented with Dilaudid 0.6 mg IV. Patient discharged POD#1 without complication and with pain adequately controlled. No additional opioids used. Sunday, October 13 1:00 PM - 2:30 PM PN MC449 Placement and Management of a Thoracic Epidural Catheter for Postoperative Analgesia in a Patient With Dual Spinal Cord Stimulators Rahul Modi, M.D., Michael Sniderman, M.D., Keck School of Medicine of USC, Los Angeles, CA 65-year-old woman (ASA 3) undergoing laparoscopic esophagectomy with gastric pullup for severe dysphagia secondary to scleroderma. She had two spinal cord stimulators implanted for Chronic Regional Pain Syndrome (CRPS) in the right lower extremity and post-herpatic neuralgia. Her pain was never controlled with the SCSs thus they were turned off and her pain physician started a regimen of Baclofen cymbalta neurontin and oxycodone. Given her history of chronic pain and the potential for converting to an open procedure we placed and managed a thoracic epidural catheter in a patient with existing dual spinal cord stimulators. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM PN MC450 Sphenopalatine Ganglion Block for Treatment of Malnutrition Related to Odynophagia and Dysphagia: A Case Report Arash Motamed, M.D., MBA, Kartik Ananth, M.D., Steven Richeimer, University of Southern California, Los Angeles, CA A 69-year-old male with tonsillar malignant squamous-cell carcinoma presented with refractory dysphagia and odynophagia secondary to severe radiation induces oral mucositis and 12.7kg weight loss. Sphenopalatine ganglion block with 1ml of 4% lidocaine instilled in each nares was performed with immediate and complete resolution of symptoms for about 10 minutes allowing time for intake of high calorie drinks. After appropriate training the patient performed this block twice daily at home. Subsequently the patient's mood and caloric intake improved bypassing the need for a gastric tube. He continued to apply the lidocaine drops for the duration of his radiation therapy. Sunday, October 13 1:00 PM - 2:30 PM PN MC451 Challenges in Treating Pain in a Patient With Systemic Botulism Shahryar Mousavi, Anthony Lebario, M.D., Donna-Ann Thomas, M.D., Steven Surrett, M.D., SUNY Upstate University Hospital, Syracuse, NY Botulism is a rare but serious paralytic illness caused by a nerve toxin that is produced by the bacteriumClostridium botulinum. This leads to paralysis usually requiring ventilation assistance. We present a 43-year-old male status-post lap band placement which was complicated by gastric erosion requiring surgical removal of the band. The patient was readmitted for symptoms of blurry vision numbness in the tip of his tongue and dizziness. He was found to be positive for Botulinum toxin from swabs of his rectum. He had resistant abdominal pain which was found to be neuropathic after response to gabapentin. Sunday, October 13 1:00 PM - 2:30 PM FA MC452 Emergency Intubation in a Patient With an Endobronchial Stent Matthew Draughon, M.D., Baylor College of Medicine, Houston, TX As anesthesiologists we should be knowledgeable about endobronchial stents and understand how to manage patients with these devices in elective and emergent situations. In our case a lung cancer patient with an in situ endobronchial silicone Y-stent had a code blue event and required emergent intubation. Due to the complex nature of the patients airway and poor communication there was difficulty with intubation. We learned that effective communication understanding the stent types and their complications and bronchoscopic visualization of the trachea and stent with careful guidance of the ETT into position are vital in securing the airway in these patients. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM FA MC453 An Imposssible Airway in the Emergency Department William Dudney, M.D., Vanderbilt University Hospital, Nashville, TN N.F. arrived to our ED after being found down. She had obvious craniofacial defects. Intubation by ED physicians had failed. The anesthesia airway team arrived with patient being ventilated by LMA. Intubation was attempted using portable video laryngoscope without success. Markedly abnormal anatomy was noted. LMA was placed but ventilation was tenuous due to aspiration. A fiberoptic intubation also failed and he patient could not be ventilated. Her airway was managed with simultaneous bronchoscopy and cricothyroidotomy by the anesthesia and ED teams respectively. Patient arrested during cricothyroidotomy and ACLS initiated. Airway could not be established and she expired. Sunday, October 13 1:00 PM - 2:30 PM FA MC454 Anesthetic Management in a Patient With Advanced Fibrodysplasia Ossificans Progressiva Cary Effertz, M.D., Edwin Rho, M.D., Mayo Clinic, Rochester, MN A 55-year-old male with Fibrodysplasia Ossificans Progressiva (FOP) presented for ureteroscopic stone extraction. Extensive heterotopic ossification of the spine jaw and larynx created unique anesthetic challenges. General anesthesia was chosen over neuraxial technique due to extensive spinal calcifications and avoidance of causing post traumatic ossification. An 18g IV was placed atraumatically. He was positioned awake and intubated via oral fiberoptic intubation. ENT was at bedside during intubation with a drill (due to overlying calcification) to assist with emergency tracheostomy if necessary. The procedure extubation and postoperative period were uncomplicated and the patient was discharged to home the following morning. Sunday, October 13 1:00 PM - 2:30 PM FA MC455 Presumed Tension Pneumothorax Nihal Eisa, M.D., Johns Hopkins Hospital, Baltimore, MD 56-year-old male with mental retardation and congenital hydrocephalus comes in after having a seizure. He has limited verbal interaction and comprehension at baseline. He was taken to the OR for VP shunt revision with no intra-op complications. Shortly after being transported to the PACU patient developed shortness of breath hypoxia hypotension and agitation. Lung sounds were diminished on the right. Neurosurgery noted they threaded the shunt with the wrong end of the wire intra-op. They performed immediate needle decompression of the right lung after which CXR showed massive right lung atelectasis. Patient was re-sedated intubated and chest tube placed. Sunday, October 13 1:00 PM - 2:30 PM FA MC456 Whether It Is Nobler to do Regional Anesthesia: Part 2 of 2 Jennifer Eldredge, M.D., Jason McKeown, M.D., University of Alabama Birmingham, Birmingham, AL A 60-year-old female with a recognized difficult airway due to a severely curved cervical spine deformity presented to an outside hospital with a right hip fracture. She could not be intubated for fixation of her Copyright © 2013 American Society of Anesthesiologists hip fracture so she was transferred to UAB for further management. The patient also had a history of lumbar spine instrumentation so the anesthesia team elected to place an intrathecal catheter for continuous spinal anesthesia. After initial difficulties the intrathecal catheter was successfully placed under fluoroscopic guidance. The patient underwent right hip hemiarthroplasty with continuous spinal anesthesia for intraoperative and postoperative pain management. Sunday, October 13 1:00 PM - 2:30 PM FA MC457 Submental Intubation: An Alternative to Tracheostomy in Maxillofacial Trauma Macdale Elwin, M.D., Michael Perrino, M.D., Parwane Pagano, M.D., David Koslovsky, M.D., Columbia University, New York, NY, Edward Chen, M.D., North Shore-LIJ Health System, Long Island, NY 21-year-old male presented after an assault during which he sustained facial trauma. Imaging showed extensive maxillofacial fractures requiring a Le Fort I fracture reduction and fixation and orbital floor reconstruction. As an oral endotracheal tube (ETT) would interfere with intraoperative occlusion and nasal intubation was contraindicated the decision was made to proceed with submental intubation. The patient was intubated orally with a flexible reinforced ETT. The surgeon then created a passage in the submental region allowing the proximal end of the ETT to be externalized while its distal portion was stabilized. ETT position was reconfirmed with fiberoptic bronchoscopy. Sunday, October 13 1:00 PM - 2:30 PM FA MC458 Abdominal ICD Replacement for a Patient With Fontan Cardiac Physiology and on Long-term Amiodarone Therapy: Anesthetic Options and Implications Joshua Emmett, M.D., Ahmad Elsharydah, M.D., UT Southwestern Medical Center, Dallas, TX A 34-year-old male was admitted for abdominal pacemaker/ICD replacement. The device was placed for sinus node dysfunction and syncope secondary to recurrent atrial arrhythmia. His cardiac history included transposition of the great vessels and single ventricle with left ventricle morphology s/p several cardiac surgeries including Glenn and modified Fontan procedures. He was started on oral Amiodarone for better control of his arrhythmia. Additionally he had a history of moderate asthma GERD and obstructive sleep apnea on CPAP. Anesthetic options were discussed with the patient and the procedure was done under uneventful MAC/local anesthesia. Sunday, October 13 1:00 PM - 2:30 PM FA MC459 Perioperative Blood Transfusion Considerations for a Patient With IgA Deficiency Presenting for Cardiac Surgery Timothy Erpelding, M.D., Lavinia Kolarczyk, M.D., UNC Hospital, Chapel Hill, NC 71-year-old male with a history of coronary artery disease severe aortic stenosis IgA deficiency and thrombocytopenia presented for CABG and AVR. Perioperative hematologic considerations included risk of coagulopathy as well as a risk of anaphylaxis to FFP and non-leukoreduced blood products. Given the high likelihood of transfusion a perioperative transfusion strategy was established. Blood conservation strategies were employed and the availability of leukoreduced blood products and FFP (donated by a known IgA deficient donor) was confirmed prior to surgery. This case illustrates the importance of perioperative collaboration between anesthesiology hematology cardiac surgery and the blood blank. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM FA MC460 An Adult Patient With Acute Epiglottitis and Croup - Approach to Emergency Airway Management Enrique Escobar, M.D., Shahla Escobar, M.D., Carl Adkins, M.D., Gerald Matchett, M.D., University of Texas Southwestern Medical Center, Dallas, TX A 48-year-old woman with a past medical history significant for psoriasis on etanercept and adalimumab presented to the emergency department with a three day history of a barking cough and throat pain. The patient developed worsening respiratory distress and was emergently transported to the operating room for airway management. After pretreatment with midazolam the patient was sedated with ketamine which improved her bronchospasm and stridor. She underwent an uneventful inhalational induction of general anesthesia with a mixture of heliox and sevoflurane with no muscle paralysis. While spontaneously breathing the patient was successfully intubated with a video laryngoscope. Sunday, October 13 1:00 PM - 2:30 PM FA MC461 Massive Postoperative Pulmonary Embolism : Cause of Cardiac Arrest in the Post Anesthesia Care Unit Arash Esmailzadegan, M.D., Roman Dudaryk, M.D., University of Miami Miller School of Medicine, Miami, FL A 54-year-old male who suffered a cardiac arrest in the PACU following operative fixation of a right femur neck and shaft fracture. ACLS algorithm was initiated leading to return of spontaneous circulation. TEE was performed immediately post arrest and demonstrated a massive pulmonary embolism and right heart strain. Infusion of tissue plasminogen activator was initiated as acute treatment of the PE in the PACU. The following day pulmonary embolectomy was performed. Sunday, October 13 1:00 PM - 2:30 PM FA MC462 When a Ruptured Uterus Turns Into a Ruptured Lung Nicole Fairweather, M.B. B.S., Francesca Rawlins, M.B. B.S., Princess Alexandra Hospital, Brisbane, Australia Failed intubation occurs in approximately 1:250 obstetric general anesthetics and despite advances in airway management devices this incidence has not changed in 20 years. Failed intubation is an important factor contributing to both maternal and fetal morbidity and mortality. With an increasing incidence of cesarean section deliveries prediction and management of the obstetric difficult airway remains an important learning point. We present a case of 'can't intubate can't ventilate' in an emergency cesarean section complicated by the development of a tension pneumothorax and bronchopleural fistula. We describe the subsequent management of the difficult obstetric airway for one lung ventilation. Sunday, October 13 1:00 PM - 2:30 PM FA MC463 Liver Biopsy and Excision of Pelvic Masses in a Patient Suspected to Have Carcinoid Syndrome Michael Fakhry, M.D., NYU Medical Center, New York, NY The patient is a 49-year-old female with a history of a T3N1 ileocolic carcinoid tumor s/p resection two years prior presenting with increasing liver and ovarian masses on MRI as well as an elevated serum Copyright © 2013 American Society of Anesthesiologists serotonin level. She underwent a diagnostic laparoscopy liver biopsy left salpingo-oophorectomy and right ovarian biopsy under GETA with an arterial line. She was pretreated with diphenhydramine famotidine and dexamethasone with octreotide readily available. The case proceeded successfully with no significant cardiopulmonary instability attributed to neuroendocrine mediators. The pathology report for the liver masses and left ovarian mass indicated metastatic carcinoid tumor. Sunday, October 13 1:00 PM - 2:30 PM FA MC464 When a Chance to Cut is Not the Best Option: An Anesthesiologist's Perspective Tania Faruque, Cleveland Clinic Foundation, Cleveland, OH An 82-year-old female presented to the ER of an outside hospital with dyspnea thyroid mass and was transferred for thyroidectomy. Her medical history there included recent pacemaker implantation with baseline 2-3rd degree heart block raising questions of adequate pacemaker function. Echocardiography revealed pulmonary pressures of 88 sytolic with good LV function and mild right ventricular dysfunction. Chest CT demonstrated tracheal compression from right-posterior mass extending to the carina including calcifications and pleural effusion. Preoperative anesthetic consultation occurred regarding potential median sternotomy but was postponed for pacemaker evaluation medical consult and repeat echocardiography to confirm outside findings. Thoracocentesis was performed. Sunday, October 13 1:00 PM - 2:30 PM FA MC465 Airway Management in Patient With Tracheal Impalement Robert Fiala, M.D., Monique Espinosa, M.D., Jackson Memorial Hospital/ University of Miami Miller School of Medicine, Miami, FL A 30-year-old male presented to our trauma center after being struck in the neck with several pieces of shrapnel from a lawnmower. Vitals were stable. There was no crepitus nor blood in the oropharynx. Physical examination revealed a high probability of tracheal impalement. The patient was taken to the OR. We performed a rapid sequence fiberoptic intubation in order to visualize any tracheal injuries and allow for both surgeons and the anesthesia team to see. The exam confirmed that the debris had penetrated the trachea. The airway management of this case was medically challenging and discussion would be enlightening. Sunday, October 13 1:00 PM - 2:30 PM FA MC466 Airway Management in a Subject with Tracheal Injury Esophageal Injury and Subcutaneous Emphysema Daria Flores, M.D., Suman Rajagopalan, M.D., Raja Palvadi, M.D., Baylor College of Medicine, Houston, TX Traumatic penetrating injury to the neck can pose a challenge to the anesthesiologist depending on the structures involved. A 23-year-old patient with multiple gunshot wounds to the neck and thorax was brought to the operating room for bronchoscopy and esophagoscopy. Endotracheal intubation was done after taking necessary cervical spine precautions. His examination revealed tracheal injury 2.5 centimeters proximal to the carina and a complete esophageal transection 25 centimeters from the incisors. The endotracheal tube was emergently exchanged for a left-sided double lumen tube while Copyright © 2013 American Society of Anesthesiologists trying to maximize oxygenation and prevent further subcutaneous emphysema in order to facilitate the surgical repair. Sunday, October 13 1:00 PM - 2:30 PM FA MC467 Postoperative Ischemic Optic Neuropathy Following Short Non-Spine Surgery in the Prone Position Marylin Fouche, University of Mississippi Medical Center, Jackson, MS This case illustrates the increased risk of ischemic optic neuropathy after non-spine prone surgery involving a 61-year-old male with history of morbid obesity diabetes mellitus and hypertension scheduled to undergo hip fracture repair. Prone positioning proved difficult due to body habitus; eyes free from pressure and neck was maintained in the neutral position. Intraoperative management involved large fluid shits subsequent to large blood loss exogenous blood administration and liberal crystalloid administration. Upon resumption of the supine position patient exhibited significant periorbital edema. Post-operative visit revealed patient with significant bilateral visual loss later shown to be ischemic optic neuropathy. Sunday, October 13 1:00 PM - 2:30 PM FA MC468 A Great Big Urology Job: But What About the Patient? Steven Boggs, M.D., MBA, Ram Roth, M.D., Elizabeth Frost, M.D., The Icahn School of Medicine, Manhattan, NY 67-year-old male with multiple medical problems including hypertension congestive heart failure CAD s/p bypass EF = 30% atrial flutter s/p ablation pulmonary hypertension (210/120) COPD asthma renal failure on dialysis anemia DM Type I opioid and cocaine dependent. Pt. had distal right ureterectomy for ureteral carcinoma the previous year now with recurrence in both bladder and right kidney and desired curative procedure - radical cystoprostatectomy with bilateral nephroureterectomies. We examine the considerations in managing a patient with significant comorbidities for an extensive procedure. Sunday, October 13 1:00 PM - 2:30 PM FA MC469 Anesthesia Considerations and Positioning Issues in a Patient With Multiple Sclerosis and Bilateral Severe Limb Contractures Needing Prone Positioning for Surgery Marc Galland, D.O., Tilak Raj, M.D., University of Oklahoma Health Sciences Center, Oklahoma City, OK, Raghuvendar Ganta, M.D., VA Medical Center, Oklahoma City, OK Patient is a 53-year-old female with history of severe MS bed-ridden with bilateral severe limb contractures worse in the lower limbs Hx of seizure disorder CVA and DM. She was scheduled for a percutaneous nephrolithotomy for removal of staghorn calculi. Particularly challenging in this case was the pharmacologic management of the patient with severe MS and the need for prone positioning for surgery made difficult by her limbs in fixed flexion. We present our successful anesthetic management and describe with clinical pictures our approach in successfully managing her positioning. Which is better for padding - foam or gel? Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM FA MC470 Successful Single Lung Ventilation With Low Fi02 During an Anterior Mediastinal Mass Excision on a Patient at Risk of Bleomycin Oxygen Toxicity Mauricio Garcia Jacques, M.D., Marc Mecoli, M.D., BIDMC, Boston, MA 28-year-old with an anterior mediastinal mass concerning for Hodgkin Lymphoma sp 5 cycles of ABVD resistant to therapy who presents to the OR for excision of residual mass and lung decortication via VATS. Her last cycle of chemotherapy was administered 20 days prior to day of surgery. The patient was induced general anesthesia with a 50% FiO2 preoxygenation and intubated with a 37F left DLT with FOB assistance and maintained with FiO2 of 30% during the case with 50% for emergence. We tolerated SpO2 of 90%. She was extubated in OR and discharged home POD#3. Sunday, October 13 1:00 PM - 2:30 PM FA MC471 Intraoperative Anaphylaxis to Thymoglobulin During Renal Transplantation Brittany Garel, M.D., The Johns Hopkins Hospital, Baltimore, MD A 50-year-old male with polycystic kidney disease presented for kidney transplantation. Induction and intubation as well as arterial and central venous catheter placement were performed uneventfully. Cefazolin dexamethasone and thymoglobulin were administered. Intraoperatively the patient abruptly became hypotensive and hypoxic developed elevated peak airway pressures and end-tidal carbon dioxide tracing declined to zero. This was followed by pulseless electrical activity. The patient was extubated reintubated and evaluated using fiberoptic bronchoscopy and TEE. The patient was treated primarily with epinephrine and albuterol. Transplantation was aborted and he was transferred to the SICU. He was extubated the following day without sequelae. Sunday, October 13 1:00 PM - 2:30 PM FA MC472 A Case of Atypical Butyrylcholinesterase and Postoperative Awareness Anthony Giberman, M.D., Richard Hirasuna, M.D., Naval Medical Center San Diego, San Diego, CA A 31-year-old female presents for tonsillectomy. Induction was with alfentanil lidocaine and propofol followed by succinylcholine oral intubation and desflurane for maintenance. At surgical completion desflurane was discontinued but the patient remained unresponsive for another hour and could not be extubated until two hours following induction. The patient was conscious but paralyzed in the OR for over 30 minutes before the diagnosis of atypical butyrylcholinesterase was suspected. Post-operative labs revealed a Dibucaine number of 27. This case highlights atypical butyrylcholinesterase as a cause of delayed awakening and the risk of awareness for affected patients while paralyzed in the operating room.

Matthew Gilbert, M.D., M.P.H., Jessica Lovich-Sapola, M.D., Case Western Reserve University Metrohealth Medical Center, Cleveland, OH One use of laryngeal mask airways (LMA) is in the ASA difficult airway algorithm. This is exemplified in our case of a 68-year-old male undergoing an exploratory laparotomy with a presumed airway obstruction after post-operative extubation. An LMA was placed and succinylcholine was administered for re-intubation. While attempting to remove the LMA the laryngeal mask separated from the plastic tubing a situation that has not yet been cited in literature. After the remaining LMA was removed the trachea was re-intubated. Post-operatively he was transported to the SICU trachea extubated on postoperative day 5 and discharged 4 days later. Sunday, October 13 1:00 PM - 2:30 PM FA MC474 Toxic Oxygen? Managing a Patient After Bleomycin Chemotherapy Laura Gilbertson, M.D., Jay Roby, M.D., University of Southern California, Los Angeles, CA A 29-year-old male with stage 3 metastatic testicular cancer presented for RPLND after three rounds of bleomycin chemotherapy. Due to concerns about development of bleomycin induced lung toxicity room air was used for induction. The patient was maintained throughout the procedure with an FiO2 below 25%. Fluid restriction was used as fluid overload has been shown to increase the incidence of pulmonary insufficiency and ARDS in patients with bleomycin exposure. The patient was extubated on room air at the end of the nine hour procedure without development of respiratory complications. Sunday, October 13 1:00 PM - 2:30 PM FA MC475 Anesthesia in an Austere Environment and Sea Lion Dive Physiology: Measuring Heart Rate and Stroke Rate in Diving California Sea Lions Ross Gliniecki, M.D., Naval Medical Center San Diego, San Diego, CA, Birgitte McDonald, Ph.D., Paul Ponganis, M.D., Ph.D., Scripps Institution of Oceanography, San Diego, CA This study measured heart rate response in sea lions foraging deep in the ocean on a single breath. The mammals were anesthetized in the field and equipped with digital electrocardiograms and time/depth/3-axis acceleration loggers. Anesthesia equipment was compact and portable: O2 tank circuit CO2 absorber volatile anesthetic vaporizer zalophyscope endotracheal tube and bite block. Anesthesia involved mask induction laryngoscopy and endotracheal intubation. Sea lions displayed bradycardia often below 10 beats min-1 in dives longer than 6 minutes. Flipper stroke rate was low for most of the dive suggesting that muscle relies primarily upon myoglobin-bound O2 for energy metabolism.

Three months prior a type II odontoid fracture required emergent tracheostomy and occiput - C4 fusion. Exam demonstrates trismus narrow oral opening narrow palate hypertrophic tongue base reduced O-C2 angle and severe tracheal stenosis. After induction ventilated only with 4.0 stomal ETT. Intubation succeeded only with retrograde passage of pediatric bougie through the stoma. Closure of the stoma was uneventful. After extubation audible stridor appreciated with rapid desaturation. Trans tracheal jet ventilation through vessel dilator cricothyrotomy maintained oxygenation until oral fiberoptic intubation was successful. Patient extubated after two SICU days. Sunday, October 13 1:00 PM - 2:30 PM FA MC477 Capnothorax With Abdominal Insufflation - Tension Running High Caron Hong, M.D., Nicholas Goehner, M.D., University of Maryland, Baltimore, MD A 57-year-old female presented for recurrent hiatal hernia repair. After induction with propofol fentanyl and rocuronium a 7.0 ETT was placed and the patient positioned supine. The abdomen was insufflated with CO2 to 15mmHg. While mobilizing the stomach end-tidal CO2 increased from 35 to >100 mmHg. ETT placement was confirmed circuit continuity assured and the surgical team informed. CO2 insufflation and surgical dissection was discontinued. The patient was hyperventilated to normocapnea within minutes. Given timing of hypercapnea with dissection around the espophageal hiatus capnothorax was suspected. The surgery was completed laparoscopically utilizing higher PEEP and lower insufflation pressures successfully. Sunday, October 13 1:00 PM - 2:30 PM FA MC478 Anesthetic Challenges in a Patient With Carcinoid Syndrome and Carcinoid Heart Disease Presenting for a Non-Cardiac Surgery Andrea Gomez Morad, M.D., Lisa Vukalcic, M.D., Saint Elizabeth's Medical Center, Boston, MA Carcinoid tumors are uncommon neoplasms capable of producing bioactive substances resulting in a variety of physiologic changes. Carcinoid syndrome can cause tricuspid and pulmonic valvular disease which can lead to severe right ventricular failure. We present a case of a 63 -year-old female with obstructive acute renal failure scheduled for a cystoscopy and bilateral nephrostomy tubes placement. She had diagnosis of carcinoid syndrome with cardiac involvement (severe tricuspid regurgitation and right heart failure). We are going to describe our management discuss the preoperative considerations intraoperative goals and postoperative care of patients with carcinoid syndrome and carcinoid heart disease.

Patient emergently taken to OR for external fixation of fracture and right popliteal artery angioplasty. External fixation done without complication 2 units PRBCs transfused. During angioplasty patient became transiently hypotensive with SBP 90s. Hematocrit dropped from 27 to 20 2 more units transfused however patient becoming increasingly hypotensive requiring multiple pressor boluses without improvement and finally infusion of 2 pressors. Multiple possible sources of bleeding surgically explored however source never found. Continued hypotension attributed to SIRS response to trauma. Sunday, October 13 1:00 PM - 2:30 PM FA MC480 To Cancel or Not to Cancel? Challenges in the Management of Repeated Intraoperative Urticaria in a Nonelective Surgery Silpa Goriparthi, M.D., Tara Kennedy, M.D., Thomas Jefferson University Hospital, Philadelphia, PA, Michael Gollotto, M.D., Our Lady of Lourdes Medical Center, Camden, NJ A 71-year-old male smoker with a history of renal cell carcinoma presented with a suspicious lung mass. Shortly after induction significant truncal urticaria was noted. The case was cancelled and allergy consultation was obtained. Skin testing of several anesthetic agents was negative. The patient returned for surgery and was pretreated with diphenhydramine and decadron. After induction he was found to have even more severe urticaria. After discussion with the allergist the case was cancelled again. We will discuss limitations of allergic skin testing of anesthetic agents and the differential diagnosis and treatment of perioperative urticaria in a non-elective surgery. Sunday, October 13 1:00 PM - 2:30 PM FA MC481 An Unusual Difficult Airway Related to Severe Kyphosis Sandra Goyal, M.D., Rush University Medical Center, Chicago, IL An 85-year-old female with a complex medical history including colon cancer and restrictive lung disease presented for right hemicolectomy. Following induction of anesthesia attempted intubation with a 7.5 endotracheal tube (ETT) failed when the ETT could not be passed beyond the vocal cords despite their grade one view with direct laryngoscopy and glidescope visualization. No tracheal stenosis or overt abnormality was seen upon airway assessment with a fiberoptic bronchoscope. Intubation was finally achieved with repeat laryngoscopy and use of a 6.0 ETT. A cervico-thoracic CT later revealed severe kyphosis with extreme tracheal curvature likely complicating passage of the 7.5 ETT.

Physical exam was significant for severely limited neck movement limited thyromental distance and Mallampati score of III. After standard IV induction intubation with a GlideScope and bougie failed. Cords were visualized however the angle was too severe to introduce the bougie. Fiberoptic bronchoscopy also failed as the cords were unable to be visualized. GlideScope was then placed and fiberoptic bronchoscope loaded with ETT was introduced into the trachea under visualization via GlideScope. ETT was then placed over bronchoscope. Sunday, October 13 1:00 PM - 2:30 PM FA MC483 No End-Tidal CO2 Secondary to Bronchospasm Mark Boswell, M.D., Ph.D., Kyle Greer, M.D., University of Louisville, Louisville, KY We describe an 18-year-old pregnant female at 23 weeks gestation with a history of asthma who presented for left video-assisted throracoscopic surgery for pneumonia and pleural effusion. Following intravenous induction and an atraumatic intubation with a double-lumen endotracheal tube no endtidal carbon dioxide was observed on capnography. The patient experienced rapid desaturation. Removal of the double-lumen tube and mask ventilation returned saturations to normal. Reintubation resulted again in no end-tidal carbon dioxide and rapid desaturation. A diagnosis of bronchospasm was made and treatment with volatile and intravenous anesthetics eventually resulted in normal waveform capnography. Sunday, October 13 1:00 PM - 2:30 PM FA MC484 Sudden drop in SaO2 With Left Lung White-Out After Induction of General Anesthesia in a Patient Undergoing Pituitary Resection for Cushing's Disease Shaun Gruenbaum, M.D., Harika Nagavelli, M.D., Alice Li, B.Sc., Benjamin Gruenbaum, M.D., Michael Hrycelak, M.D., Yale University School of Medicine, New Haven, CT A 27-year-old female with history of Cushing's disease obesity was scheduled for endonasal transsphenoidal resection of a pituitary tumor. After uneventful induction of general anesthesia and endotracheal intubation the patient had sudden drop in Sa02 to 81% that did not improve with manipulation of mechanical ventilation settings. ABG revealed PaO2 of 82 despite FiO2 of 100%. After several minutes of ventilation PaO2 improved to 130 chest x-ray demonstrated complete white-out of the left lung. The case was cancelled and the patient was transported to NICU where she improved and was extubated within a few hours.

Shaun Gruenbaum, M.D., Benjamin Gruenbaum, M.D., Alice Li, B.Sc., Harika Nagavelli, M.D., David Silverman, M.D., Yale University School of Medicine, New Haven, CT A 27-year-old female with a history of Cushing's Disease secondary to pituitary tumor was evaluated in the preoperative clinic. She had a 90 lbs weight-gain over 4 years insomnia buffalo hump moon facies acne depression and borderline hyperglycemia. On questioning she reported daily episodes of unprovoked tachycardia to 120 associated with palpitations and dyspnea. Per the patient's primary doctor she had previously demonstrated runs of supraventricular tachycardia and atrial fibrillation of unclear etiology on Holter monitor. A pheocromoctyoma was suspected and we considered whether the case needed to be delayed for further workup. Sunday, October 13 1:00 PM - 2:30 PM FA MC486 Anesthetic Implications and Considerations During Paraganglioma Resection Ryan Gualtier, M.D., NYU School of Medicine, New York, NY 35-year-old female with PMH of HTN and HCV presented with two-year history of right flank pain night sweats and palpitations. Upon initial workup the 24-hour urine metanephrines were highly positive. MRI CT and MIBG scans confirmed presence of 3.5cm hypervascular mass medial to the IVC consistent with a paraganglioma. The patient was medically optimized for surgery including blood pressure control with Phenoxybenzamine and Metoprolol. Intra-operatively blood pressure was extremely labile due to IVC compression and manipulation of the paraganglioma causing massive catecholamine surges. Dexmedetomidine Phenoxybenzamine Nitroglycerin and Esmolol were utilized to blunt the catecholamine response and rapidly control blood pressure. Sunday, October 13 1:00 PM - 2:30 PM RA MC487 Naltrexone Induced Opioid Supersensitivity Rocco Landi, M.D., Mark Shulman, M.D., St. Elizabeth's Medical Center, Brighton, MA Naltrexone is a pure antagonist of the mu opioid receptor with up-regulatory effects on receptor expression with chronic exposure. We present the case of a 61-year-old female with a hepatic mass scheduled for segmental liver resection and cholecystectomy. Unbeknownst to the anesthetic team the patient had undergone chronic naltrexone treatment under the care of her psychiatrist. After receiving 0.6 mg of epidural hydromorphone intraoperatively the patient experienced profound respiratory depression resistant to naloxone reversal. We describe our management and review the literature exploring the effects of chronic naltrexone treatment on mu-opioid receptor expression and activity.

Sunday, October 13 1:00 PM - 2:30 PM RA MC490 Bilateral Transversus Abdominis Plane Catheters for Peri-perative Pain Control in a Patient With Reflex Sympathetic Dystrophy With a Spinal Cord Stimulator Undergoing an Open Right Hemicolectomy: A Case Report. Natasha Malackany, D.O., Hesham Elsharkawy, M.D., Kamal Maheshwari, M.D., Wael Ali Sakr Esa, M.D., The Cleveland Clinic, Cleveland, OH We report the peri-operative management of bilateral transversus abdominis plane (TAP) catheters in a patient with reflex sympathetic dystrophy with a spinal cord stimulator who underwent an open right hemicolectomy. Bilateral TAP catheters were placed pre-operatively under ultrasound-guidance and tunneled backward away from the surgical field. 15 mL of ropivicaine 0.5% was injected to each side and ropivicaine 0.2% was infused continuously at 8mL/hour. The patient required minimal narcotics postoperatively only while her spinal cord stimulator was off. TAP catheters are an option for peri-operative pain management in patients with reflex sympathetic dystrophy and spinal cord stimulators undergoing abdominal surgery. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM RA MC491 What to do With an Epidural Catheter in a Patient who Becomes Placed on ECMO? Behram Mehta, M.D., Ehab Farag, M.D., Cleveland Clinic, Cleveland, OH This was a 79-year-old male with a past medical history of T2N0M0 esophageal adenocarcinoma and prostate cancer who underwent an esophagectomy. The patient had a T8-9 epidural placed preoperatively for postoperative pain control. Early in the postoperative course the patient had an evolving posterolateral MI from an occluded left circumflex which was treated with stent placement IABP and initiation of V-V ECMO. Patient received clopidogrel and abciximab during stenting and was subsequently started on a heparin drip. Now that the patient was receiving full anticoagulation the medically challenging question was when could the patient's epidural catheter be removed? Sunday, October 13 1:00 PM - 2:30 PM RA MC492 Using a Double Epidural Technique for Postoperative Analgesia: A Case Study Tucker Mudrick, M.D., Brian Allen, M.D., Vanderbilt University Medical Center, Nashville, TN A 46-year-old male taking 950mg PO morphine per day underwent abdominoperineal resection with end colostomy sacrectomy bilateral gluteal rotational flaps and bilateral ureteral stents for invasive SCC of his anus and sacrum. Patient was extubated on POD#1 and complaining of excruciating pain despite being on ketamine and high dose fentanyl infusions. We performed a double epidural technique at T10 and L3 which resulted in almost complete resolution of the patient's pain. Ketamine and fentanyl infusions were weaned off shortly afterwards and patient was able to actively participate in physical therapy. Patient was discharged on POD#9 in excellent condition Sunday, October 13 1:00 PM - 2:30 PM RA MC493 Bilateral Continuous Thoracic Paravertebral Block and Intrathecal Duramorph for Hand-Assisted Laparoscopic Hepatectomy in a Patient With Type 1a Glycogen Storage Disease: A Case Report. Anastacia Munro, Trusha Govindji, M.D., Donald Bohannon, M.D., Andre Boezaart, M.D., UF Shands, Gainesville, FL A 16-year-old male with Type Ia glycogen storage disease underwent a hand-assisted laparoscopic left lateral hepatectomy for a hepatic adenoma-hepatocellular carcinoma. Surgcally-induced stress and pain are triggers for elevation of lactate and problems with glucose homeostasis therefore adequate pain control was imperative. This was achieved with intrathecal morphine and bilateral continuous thoracic paravertebral blocks placed pre-operatively and supplemented with a hydromorphone patientcontrolled analgesia on postoperative day (POD) 1. Catheters were removed on POD 3. During hospitalization glucose and lactic acid levels were monitored frequently and returned to pre-operative levels prior to discharge. Patient was discharged home on POD 7. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM RA MC494 Ultrasound-Guided Axillary Nerve Block in a Patient With Chronic Inflammatory Demyelinating Polyneuropathy: A Case Report Kristen Pastor, M.D., Emily Nelson, M.D., Brigham and Women's Hospital, Boston, MA Chronic inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated disease of the peripheral nervous system. We present a case of a 69-year-old man with CIDP for upper extremity surgery performed under axillary block. He presented with lower extremity numbness and weakness; previous upper extremity symptoms had improved with IVIG infusions. An ultrasound guided axillary nerve block with 40 mL of 1.5% mepivicaine provided successful anesthesia of the patient's distal arm for the case and he received minimal intravenous sedation with a natural airway. Postoperatively he had complete resolution of the block with no residual motor or sensory deficits. Sunday, October 13 1:00 PM - 2:30 PM RA MC495 Combined Interscalene-Superficial Cervical Plexus Blocks for Surgical Repair of Clavicular Fracture in a Pregnant Patient of 15 Week's Gestation Eamon O'Murchu, M.D., Malikah Latmore, M.D., Admir Hadzic, M.D., St Luke's Roosevelt Hospital Center, New York, NY, Catherine Vandepitte, M.D., University Hospitals Leuven K.U.L, Leuven, Belgium A 32-year-old woman at 15 weeks gestation was admitted with a unilateral mid-shaft displaced clavicular fracture sustained during an automobile collision. A single injection interscalene brachial plexus block and a superficial cervical plexus block were performed under ultrasound guidance followed by successful surgical reduction of the fracture. Interscalene brachial plexus blocks are commonly used at our institution as a single anesthetic modality for surgery on the clavicle. While most anesthetic agents are considered safe in pregnancy recent animal studies suggest that anesthetic agents may present harm to the developing fetus and a regional technique may be preferred. Sunday, October 13 1:00 PM - 2:30 PM RA MC496 Posterior Thigh Abscess Following Continuous Popliteal Sciatic Nerve Block in the Ambulatory Setting Jason Panchamia, D.O., Michael Ritchey, M.D., Cleveland Clinic, Cleveland, OH A 61-year-old female was scheduled for elective right ankle surgery. A preoperative popliteal sciatic nerve catheter was placed in a sterile fashion under ultrasound guidance. Intraoperative course was uneventful and the patient was discharged with an ambulatory infusion pump. On postoperative day four the patient was hospitalized for right leg cellulitis and a deep posterior thigh abscess located at the popliteal catheter site which was confirmed with imaging studies. Subsequently she underwent multiple incision and drainage in addition to a prolong course of intravenous antibiotics. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM RA MC497 Bad Lungs Bad Heart Bad Hip: The Anesthestic Management of a 93-year-old With Mycobacterium Avium Intracellulare and Aortic Stenosis Laura Park, M.D., Michael Bialos, M.D., Icahn School of Medicine at Mount Sinai, New York, NY 93-year-old M with h/o CAD moderate AS and Mycobacterium avium intracellulare presenting with L femur fracture requiring hemiarthroplasty. As the pt had poor pulmonary function pt's pulmonologist felt that avoiding GA would be best due to probable difficulty weaning from ventilator. Surgery team and pulmonologist urged for a regional anesthestic technique to be implemented. Given the AS large bore IV's and a preinducation A-line were established after which multiple attempts at placing an epidural were unsuccessful. Though a relative contraindication due to the AS a spinal anesthetic was placed and pt was started on a phenylephrine infusion with close hemodynamic monitoring. Sunday, October 13 1:00 PM - 2:30 PM RA MC498 Use of Continuous Spinal Anesthesia in a Patient With Severe Aortic Stenosis and Pulmonary Hypertension Ronak Patel, Sarah Clarke, D.O., Michael Terreri, M.D., TJUH, Philadelphia, PA Pulmonary hypertension and aortic stenosis are two disease processes associated with increased morbidity and mortality. These conditions present the unique challenge of creating a fine balance between sympathetic activity cardiac output coronary perfusion pulmonary vascular resistance and systemic vascular resistance. Central neuroaxial anesthesia has historically been contraindicated in patients with severe aortic stenosis secondary to marked decreases in systemic vascular resistance. In addition general anesthesia has been the method of choice for intraoperative management of the patient with pulmonary hypertension. Here we discuss the use of continuous spinal anesthesia for a patient with severe aortic stenosis and severe pulmonary hypertension. Sunday, October 13 1:00 PM - 2:30 PM RA MC499 Horner's Syndrome After Thoracic Epidural in a Patient With Ehler-Danlos Syndrome Ravi Pathak, M.D., Jingping Wang, M.D., Massachusetts General Hospital/Harvard Medical School, Boston, MA Presented is a case of miosis and ptosis in a 43-year-old female with history of Ehler-Danlos syndrome underwent sigmoid resection rectopexy and urethral sling under general anesthesia and low thoracic epidural which was placed pre-operatively. Post-operatively the pain service was asked to come evaluate the patient for blown pupil. Upon evaluation the patient had miosis and ptosis of the right eye with no other neurological signs or symptoms. The symptoms resolved within 24 hours with no sequelae. With a brief review of the literature risk factors for miosis and ptosis are discussed. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 1:00 PM - 2:30 PM RA MC500 The Addition of Dexamethasone in a Peripheral Nerve Block in Lieu of a Peripheral Nerve Catheter Christopher Paul, M.D., Anjali Patel, D.O., Saint Louis University, St. Louis, MO A 19-year-old female presented in the recovery room for peripheral nerve block for postoperative pain control status post open reduction and internal fixation of a lisfranc injury. In order to provide a long acting block while avoiding the potential complications of a peripheral nerve catheter we have begun adding dexamethasone to single shot peripheral nerve blocks. This patient had sustained complete sensory and motor block for greater than 30 hours with complete resolution at 56 hours after single shot lateral popliteal block placement. Patient had no residual sensory/motor deficits at outpatient follow-up. Sunday, October 13 1:00 PM - 2:30 PM RA MC501 Thromboelastography for Evaluation of Epidural Removal in a Thrombocytopenic Patient Christopher Paul, M.D., Anjali Patel, D.O., Saint Louis University, St. Louis, MO A 52-year-old male s/p liver and liver/kidney transplant presented for ventral hernia repair. Based on previous labs and no other contraindications an epidural for analgesia was placed. It was requested the epidural be removed on POD #5 for discharge the subsequent day. However due to platelet count of 75 000 the epidural was not removed. As platelet transfusion was not an option for this patient a thromboelastogram was performed the following day with subsequent epidural removal. Neurologic examination by nursing was ordered every hour for 24hours for evaluation of epidural hematoma. Patient discharged without complications. Sunday, October 13 1:00 PM - 2:30 PM RA MC502 Isolated Lower Extremity Motor Block Following Thoracic Epidural Placement Kelly Price, Stephanie Yacoubian, M.D., Brigham and Women's Hospital, Boston, MA 84-year-old female with a new right sided lung mass scheduled for robotic assisted wedge resection. In the pre-op holding area thoracic epidural was placed under minimal sedation at T6-T7 in two attempts with no unusual observations at time of placement. Following placement aspiration of the catheter was negative for CSF and a test dose of 3cc 1.5% lidocaine with 1:200 000 epinephrine was administered. On exam prior to induction of anesthesia patient was noted to have an appropriate T4-T9 sensory level and complete motor block of the left lower extremity in the absence of any lower extremity sensory changes. Sunday, October 13 1:00 PM - 2:30 PM RA MC503 Rotation of Continuous Peripheral Nerve Catheters to Provide 18+ Days of Pain Relief Yawar Qadri, M.D., Ph.D., Arun Ganesh, M.D., Cody Rowan, M.D., Randall Coombs, M.D., University of North Carolina at Chapel Hill, Chapel Hill, NC A 37-year-old male suffered a degloving injury of his dominant upper extremity. As the limb was neurovascularly intact multiple operations were attempted to salvage the limb. A supraclavicular brachial plexus catheter was placed for surgical anesthesia. After an initial salvage operation localized Copyright © 2013 American Society of Anesthesiologists bacterial and fungal osteomyelitis was noted. Due to the need for multiple operations nerve catheters were rotated to provide almost three weeks of continuous brachial plexus blockade minimizing opioid and general anesthetic exposure. A multimodal management plan for the patient's orthopedic injuries was established. Unfortunately the patient went on to require amputation and developed phantom limb pain. Sunday, October 13 1:00 PM - 2:30 PM RA MC504 Assessing Platelet Function Prior to Removal of Epidural Catheter From Patient Given Clopidogrel John Reynen, M.D., Kristopher Schroeder, M.D., University of Wisconsin, Madison, WI A 68-year-old male with CAD and remote coronary stent placement received a thoracic epidural for postoperative pain control for an Abdominoperineal Resection. While on heparin and aspirin the primary team restarted his home medication clopidogrel POD#3-5. Risk of epidural hematoma versus epidural abscess was balanced when planning catheter removal. Thromboelastography was utilized on the day of planned removal to assess for platelet function as well as his functional coagulability. The epidural catheter was removed POD#8 without complication after the thromboelastogram demonstrated normalized platelet function. No neurologic deficits presented after 24 hours of close monitoring. MCC Session Number – MCC08 Sunday, October 13 3:00 PM - 4:30 PM FA MC505 Perioperative Management of the Patient With Oral Basal Disorder Ethan Reynolds, M.D., Hui Yuan, M.D., Saint Louis University, Saint Louis, MO A 38-year-old female at 27 weeks gestation presented to the operating room emergently for incision and drainage of a submental odontogenic abscess. Awake fiberoptic intubation in the operating room allowed successful placement an ETT. With little improvement in the airway anatomy the decision was made to keep the patient intubated. Self extubation in the recovery area required emergent reintubation. The ETT was initially removed and successful bag mask ventilation commenced. Following an unsuccessful attempt using a video laryngoscope an LMA was placed allowing successful ventilation. Fiberoptic bronchoscope was then used through the LMA to secure the airway. Sunday, October 13 3:00 PM - 4:30 PM FA MC506 Management of Von Willebrands Disease in a Jehovah's Witness Presenting for Radical Nephrectomy Justin Richads, M.D., Jonathan Wanderer, M.D., Vanderbilt University, Nashville, TN WB is a 60-year-old male with a history of von Willebrands disease who presents with a right renal mass for laparoscopic radical nephrectomy. He is a Jehovah's Witness and refuses blood products. Preoperatively he was evaluated by the hematology service which recommended infusion of antihemophilic factor/von willebrand factor complex in the perioperative period. He underwent the above procedure without complication; intraoperative estimated blood loss was 50ml. Postoperatively he completed the prescribed antihemophilic factor/von willebrand factor complex infusion. He was Copyright © 2013 American Society of Anesthesiologists discharged on post-operative day three with a hemoglobin of 8.3 mg/dl and without signs or symptoms of anemia. Sunday, October 13 3:00 PM - 4:30 PM FA MC507 Anesthetic Management of a Patient With Severe Wegener's Granulomatosis Undergoing Laryngotracheobronchoplasty Janice Riso, M.D., Franco Resta-Flarer, M.D., Jonathan Lesser, M.D., Junping Chen, M.D., Ph.D., St. Luke’s Roosevelt Hospital Center Columbia University College of Physicians and Surgeons, New York, NY A 54-year-old female with Wegener's Granulomatosis acute renal failure on hemodialysis and multiple hospitalizations secondary to respiratory failure underwent a tracheoplasty for worsening respiratory status due to tracheal stenosis. The patient continued to deteriorate and was taken back to the OR 21 days later for laryngeal dilation and excision of granulomatous tissue. Over the next 2 months her symptoms continued to decline and tracheostomy became necessary. Tracheostomy was performed along with bronchoscopy and tracheal balloon dilation. 9 days later the patient required additional laryngotracheoplasty endoscopic bronchial dilation and tracheostomy exchange. Sunday, October 13 3:00 PM - 4:30 PM FA MC508 Management of Massive Airway Bleeding in a Patient With a History of Descending Thoracic Aortic Aneurysm Repair Pragati Rohatgi, M.D., Soumya Nyshadham, M.D., Lars Helgeson, M.D., Yale University School of Medicine, New Haven, CT A 36-year-old male with 10 years prior history of thoracic aortic aneurysm repair presented with massive hemoptysis and cardiac arrest. Patient was resuscitated and intubated in ED with X-ray revealing left lung opacity and widened mediastinum. Anesthesiology was consulted for right lung isolation and tamponade of left sided intrapulmonary bleed. Fiberoptic bronchoscopy via ETT failed to identify any anatomical structures due to massive bleeding. Ventilation and oxygenation became compromised. The endotracheal tube was successfully replaced with a left-sided DLT over cook exchange catheter and bag ventilation continued. Patient again arrested was resuscitated and subsequently expired. Autopsy revealed left aorto-pulmonary erosions. Sunday, October 13 3:00 PM - 4:30 PM FA MC509 Laparoscopic Cholecystectomy in an Adult Patient With Complicated Cystic Fibrosis Santiago Rojas Paez, M.D., Thea Rosenbaum, M.D., University of Arkansas for Medical Sciences, Little Rock, AR A 20-year-old male patient with acute cholecystitis was scheduled for cholecystectomy. He has history of Cystic Fibrosis complicated by severe airway obstructive involvement prior pneumothorax and diabetes. He was medically optimized and pulmonary consultation recommended elective extubation in ICU. Patient underwent procedure with general endotracheal anesthesia. At the end of surgery opioid analgesics were generously tritiated based on respiratory rate to provide comfort on emergence. Patient met extubation criteria and was extubated in close communication with surgeon and pulmonologist. He was transferred to ICU with continued Cystic Fibrosis care.

The cricothyrotomy was complicated by a traumatic pneumothorax which resulted from incorrect placement of the bougie intubating introducer. This case both illustrates a potential complication of this airway technique and highlights the need for vigilance to diagnose and manage a pneumothorax. Sunday, October 13 3:00 PM - 4:30 PM FA MC511 Anesthetic Management of a Patient With Post-Legionnaires' Anti-Acetylcholine Antibody Syndrome (anti-AChR) and Ischemic Cardiomyopathy David Dahl, M.D., Michael Hosking, M.D., University of Tennessee Knoxville, Knoxville, TN A 76-year-old male requiring surgical incision and drainage of a peri-rectal abscess. Approximately one year prior he contracted Legionnaires' Disease. He developed progressive skeletal muscle weakness leading to prolonged intubation and tracheostomy. Extensive evaluation was negative for malignancy and he was diagnosed with post infectious anti-AChR syndrome. He remained unable to to ambulate but no longer required tracheostomy. Other complicating medical factors included ischemic cardiomyopathy with an EF of 25% and presence of an ICD. Anesthetic management was complicated by uncertain effect of neuromuscular blockers compromised cardiac function and the need for prone positioning. Sunday, October 13 3:00 PM - 4:30 PM FA MC512 Unknown Pseudocholinesterase Deficiency in a Patient With Extensive Previous Surgical History Julia Rosenbloom, M.D., Jeremy Burke, M.D., Jodi Sherman, M.D., Yale University School of Medicine, New Haven, CT 43-year-old white female with poorly-controlled type-two diabetes and hypertension presented for emergency cystoscopy. Past anesthetics including for acute appendicitis were reported unremarkable and patient denied familial anesthetic complications. Patient underwent RSI with succhinylcholine in the operating room; at the end of the procedure (15 minutes from induction) patient had 0/4 twitches. After 45 additional minutes under GA patient had 1/4 twitches. Patient was transported to ICU with presumed diagnosis of pseudocholinesterase deficiency and required ventilator assistance for four hours prior to extubation. Pseudocholinesterase deficiency may not have been evident with prior anesthetics due to variations in practice or patient-centered features. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC513 Anesthesia Management for Extensive Tracheal Papillomatosis Omolola Salaam, M.D., Mohamad Hashim, M.D., Maimonides Medical Center, Brooklyn, NY 48-year-old male with extensive tracheal papillomatosis presented with severe stridor and dyspnea. CT scan showed over 90% obstruction of the trachea extending from the vocal cord to the carina. He was scheduled for tracheal balloon dilatation and stent placement. General anesthesia was induced and jet ventilation was placed at the level of the vocal cord to maintain adequate oxygenation. Tracheal balloon dilatation was performed over a guide wire followed by deployment of two tracheal stents to maintain the lumen patency. He was recovered and discharge home the same day. Sunday, October 13 3:00 PM - 4:30 PM FA MC514 Total Thyroidectomy in a Pregnant Patient Craig Samford, M.D., Wolf Kratzert, M.D., University of New Mexico, Albuquerque, NM A 28-year-old female with a past medical history significant for Grave's disease complicated by a goiter bilateral hemianopsia atrial tachyarrhythmia and several spontaneous abortions was admitted to the Otolaryngology service for elective thyroidectomy following unsuccessful medical management. The patient presented with tachyarrhythmia at 150 bpm and an anterior neck mass measuring 9-10 centimeters. Due to suboptimal treatment of her hyperthyroidism surgery was delayed with the goal of rate and arrhythmia control and euthyroid labs. On preoperative anesthesia evaluation the patient reported difficulties breathing when lying flat on her back. Routine urine pregnancy test in the preoperative area was positive. Sunday, October 13 3:00 PM - 4:30 PM FA MC515 Intrathoracic Fire Rohin Sarkar, M.D., University of New Mexico, Albuquerque, NM 60-year-old male with BPH asthma and a chronic empyema with chest tube presented for a bronchoscopy partial open thoracoplasty and revision of the Eloesser flap. A single lumen tube was placed in the trachea for a video bronchoscopy and then exchange to a double lumen tube was tried. However the double lumen tube did not pass and the single lumen was too short to mainstem therefore the procedure was begun with double lung ventilation. During the lysis of an adhesion between the lung and the chest wall a flame was noted in the surgical field with the use of electro-cautery. Sunday, October 13 3:00 PM - 4:30 PM FA MC516 Anesthetic Management of Donor Nephrectomy for a Recipient With a History of Malignant Hyperthermia Jacob Schaff, M.D., Rob Maniker, M.D., Columbia University, New York, NY A 56-year-old woman presented for living-related donor nephrectomy. The recipient had reported a personal history of malignant hyperthermia (MH) requiring ICU admission. Sevoflurane levels have been measured in rat kidneys up to two days after its discontinuation. With this in mind we chose a nontriggering anesthetic with propofol and remifentinil infusions for the donor to avoid possible triggering Copyright © 2013 American Society of Anesthesiologists via the transplanted kidney to the MH-susceptible recipient. Both patients had uneventful procedures and were discharged without complications. This example underscores the importance of communication among anesthesia teams to promote patient safety especially in the context of living related transplantation. Sunday, October 13 3:00 PM - 4:30 PM FA MC517 The Effects of Buprenorphine on Anesthetic Dosing Jacob Schauer, M.D., Yury Khelemsky, M.D., Mount Sinai Medical Center, New York, NY A 44-year-old female on buprenorphine-naloxone maintenance for opioid dependence presented for emergent anterior decompression and stabilization of a cervical spine fracture. Intraoperative neurophysiological monitoring prevented use of paralytics and inhalational anesthetics. Anesthetic maintenance included propofol and remifentanil infusions. Intraoperative patient movement was uncontrolled with very high doses of propofol and remifentanil. Movement in response to surgical stimulation was ablated only after the addition of ketamine. Seven days later after discontinuation of buprenorphine-naloxone and transition to maintenance with methadone a posterior cervical arthrodesis was performed. She had drastically reduced anesthetic requirements during this case illustrating buprenorphine's profound effect on anesthetic dosing. Sunday, October 13 3:00 PM - 4:30 PM FA MC518 The Use of a Fiberoptic Bronchoscope as a Steerable Stylet for a Glidescope Assisted Intubation of a Difficult Airway Krystal Scherrer, M.D., Michael Lasky, M.D., Saint Louis University, St Louis, MO A 46-year-old M presented for craniotomy. This patient's PMH included left tonsil SCC s/p chemotherapy/radiation. On exam the patient was a Mallampati I had a normal thyromental distance marginal mouth opening and left facial paralysis. DL was performed with a MAC 4 blade but only the epiglottis could be visualized. We then attempted with the GlideScope™; and found the patient's airway deviated significantly and could not pass a styletted ETT. The ETT was then loaded onto the bronchoscope. With the bronchoscope acting as “steerable” stylet we inserted the ETT between the cords under direct view of the GlideScope™. Sunday, October 13 3:00 PM - 4:30 PM FA MC519 Cricothyrotomy in the Post Anesthesia Care Unit Due to Expanding Hematoma Following Anterior Cervical Spine Surgery Rupa Sekhar, M.D., Zana Borovcanin, M.D., University of Rochester Medical Center, Rochester, NY 52-year-old female presented with neck hematoma one hour after anterior cervical decompression and fusion. Anesthesia was paged emergently to PACU due to respiratory distress. A left neck hematoma expanding to midline and right neck was visible. Surgical team attempted to evacuate the hematoma. Trauma surgery was present with cricothyrotomy tray. Airway topicalization was performed. Attempted awake intubation with Glidescope was unsuccessful resulting in can't ventilate can't intubate situation. Decision was made to proceed with cricothyrotomy. After securing the airway the patient was taken to the OR for formal wound exploration and conversion to tracheostomy. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC520 Challenges of Airway Management Posed by Upper Airway Fistulas Goonjan Shah, Harendra Arora, M.D., University of North Carolina, Chapel Hill, NC We describe a case of a difficult airway in a 68-year-old male patient who presented for sinus surgery. The patient had a large left orbital defect from a previous left orbital exenteration. After anesthesia induction with propofol mask ventilation was extremely difficult due to air-leak from a communication between the nasopahrynx and the orbit. Despite the use of saline-soaked gauze to cover up the orbital defect mask ventilation was extremely difficult. Once patient was breathing spontaneously endotracheal intubation was achieved with a fiberoptic. We will discuss the challenge posed by upper airway fistulas and review the difficult airway algorithm. Sunday, October 13 3:00 PM - 4:30 PM FA MC521 Difficult Airway in a Patient With Tracheal Stenosis Mehul Shah, Stanlies D'Souza, M.D., Toni Chahla, M.D., Baystate Medical Center, Springfield, MA A 51-year-old female with known tracheal stenosis secondary to prior traumatic emergent intubation presented for CABG with triple vessel disease. During asleep fiberoptic intubation an abnormal soft tissue web-like structure was noticed in the right lateral trachea at 18 cm from incisor level. Following unsuccessful attempted intubation with 6.0 size tube an LMA was placed and patient was awakened. In a separate setting asleep fiberoptic aiway evaluation showed 7-10 mm long tracheal stenosis beginning 3.5 cm distal to the vocal cords. This stenosis required ballon dilatation and the procedure was performed over an properly positioned LMA. Sunday, October 13 3:00 PM - 4:30 PM FA MC522 Pneumothorax During Laparoscopic Paraesophageal Hernia Repair Jessica Shanahan, M.D., T. Anthony Anderson, M.D., Massachusetts General Hospital, Boston, MA A 64-year-old male with paresophageal hernia GERD and emphysema with no recent flares underwent laparoscopic paraesophageal hernia repair. An hour after induction the patient became acutely hypoxemic and hypotensive. No breath sounds were auscultated on the left. Increasing FiO2 hyperventilation and cessation of abdominal insufflation initially improved hypoxemia. Emergency flexible bronchoscopy revealed mucus plugging which was aggressively suctioned. Stat chest x-ray showed a very small left apical-medial pneumothorax unable to be appreciated on the OR monitors. Hypoxemia and hypotension recurred with reinsufflation of the abdomen. Definitive management was a left-sided chest tube. Sunday, October 13 3:00 PM - 4:30 PM FA MC523 Malignant Hyperthermia in a Healthy 23-year-old Male During the Second of Two Anesthetic in One Day Anna Shapiro, M.D., Jesse Shurter, M.D., University of California San Diego, San Diego, CA A healthy 23-year-old man underwent two procedures 10 hours apart. First was a traumatic abdominal hernia repair. Anesthesia induced with lidocaine 100mg etomidate 20mg and succinylcholine 100mg and Copyright © 2013 American Society of Anesthesiologists maintained with sevoflurane was uneventful. Ten hours later with a nearly identical anesthetic technique he underwent scapula wash-out. He became rigid during prepping and within ten minutes developed tachycardia hypercarbia and elevated airway pressures. Sevoflurance was discontinued IV dantrolene administered and he remained intubated overnight. CPK peaked at 11 755 and muscle biopsy showed necrosis. Malignant hyperthermia can present in patients who have very recently undergone a potentially triggering anesthetic without incident. Sunday, October 13 3:00 PM - 4:30 PM FA MC524 Carcinoid Crisis Brought on by Laryngoscopy Alok Sharma, M.D., Michael Alvarado, M.D., Pablo Guzman, M.D., University of California San Francisco, San Francisco, CA We describe the case of a 62-year-old female with small bowel carcinoid tumor metastatic to liver who developed carcinoid crisis (whole body flushing severe hypotension) upon induction of general anesthesia for a toe amputation for melanoma. Preoperatively she had daily episodes of flushing and wheezing despite therapy with octreotide. On the day of surgery she took her prescribed octreotide and received another subcutaneous octreotide injection prior to OR. Intraop resuscitation was successful with vasopressin IV octreotide infusion and epinephrine and surgery was aborted. Her toe ampuation was later completed uneventfully under spinal after overnight pretreatment with intravenous octreotide. Sunday, October 13 3:00 PM - 4:30 PM FA MC525 Reishi Mushroom's Antiplatelet Like Effects Leads to Unexpected Intraoperative Complications Shelly Sharma, M.D., Bernadette Cracchiolo, M.D., Shubhangi Kesavan, M.D., Steve Shulman, M.D., M.S., Anthony Sifonios, M.D., UMDNJ New Jersey Medical School, Newark, NJ Reishi mushroom has antihypertensive anti-tumor and antiplatelet effects. A 64-year-old female with cervical cancer properatively without disclosing it. Robotic radical hysterectomy was planned and begun but blood oozed from all sites of dissection despite use of cautery. Therefore procedure was converted to laparotomy. FFP did not improve her coagulation. After administration of platelets clot formation was visualized and oozing stopped. She required 3 units of PRBC. Reishi mushroom contains protease and polysaccharides that contribute to its antiplatelet effect. It should not be ingested before surgery as this can lead to unexpected blood transfusion and prolong intubation. Sunday, October 13 3:00 PM - 4:30 PM FA MC526 Cardiovascular Collapse in a Patient With Multiple Co-Morbidities Undergoing Parathyroidectomy Uttam Shastri, M.D., University of Texas Southwestern, Dallas, TX A 67-year-old female with PMH of stable angina HTN and IDDM was scheduled for a parathyroidectomy. Echo showed normal LV function and diastolic dysfunction. After induction the head was positioned in extension. Maintenance included sevoflurane and remifentanil infusion. The patient then became bradycardic hypotensive and lost carotid pulse. The head was immediately placed in neutral position. Chest compressions were started atropine 1 mg IV was given. The HR increased to 85 with systolic BP remaining 60-65. Vasopressin 15 units was administered. The case was aborted and patient was transferred to the ICU intubated. She was discharged without residual effects. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC527 Intraoperative Hyperkalemia and CRRT Initiation Lisa Shaw, M.D., University of Michigan, Ann Arbor, MI This is a 66-year-old male for repair of an enterocutaneous fistula with end-stage renal disease (ESRD) severe gastroparesis and history of tracheostomies. We were faced with managing his airway and contending with hyperkalemia thereafter. Continuous renal replacement therapy (CRRT) was initiated which then led to hypothermia and coagulopathy. Research surveyed includes a review of potassium and hyperkalemia the use of succinylcholine versus rocuronium for rapid sequence intubations the use of succinycholine and lactated ringers in ESRD patients the potential existence for potassium tolerance and finally treatment options for hyperkalemia including indications for and complications of intraoperative CRRT. Sunday, October 13 3:00 PM - 4:30 PM FA MC528 Anesthetic Management of a Patient With Fibrodysplasia Ossificans Progressiva John Shepler, George Arndt, M.D., Richard Galgon, M.D., University of Wisconsin School of Medicine and Public Health, Madison, WI A 46-year-old man with severe global heterotopic ossification and extra-articular joint ankylosis from fibrodysplasia ossificans progressiva presented for ureteroscopy and laser lithotripsy. Anesthesia management was challenged by complete mandibular and cervical spine fixation extensive anterior neck soft tissue ossification precluding a surgical airway global joint fixation requiring positioning attention and severe restrictive lung disease. Successful anesthetic management included small gauge intravenous cannulation an awake bronchoscopic wire-guided nasal intubation careful intra-operative positioning neuromuscular blocking drug use avoidance non-opioid analgesia an awake extubation and a careful post-operative monitoring plan. Safe home discharge occurred on post-operative day 1. Sunday, October 13 3:00 PM - 4:30 PM FA MC529 Perioperative Coagulation Status Monitoring: Thromboelastography (TEG) or Laboratory Testing? Shashank Shettar, M.D., Kyota Fukazawa, M.D., Ernesto Pretto, M.D., M.P.H., Jackson Memorial Hospital and Miller School of Medicine University of Miami, Miami, FL A 59-year-old patient with HCV cirrhosis and prosthetic valves (aortic mitral) presented for liver transplantation. The patient was anti-coagulated (warfarin) until the day of transplant. Pre-transplant labs showed prolonged PT-INR APTT but normal fibrinogen and platelets. In contrast TEG in the OR showed normal ‘time to coagulation' (R) with wide maximum amplitude (MA). The discrepancy between laboratory tests and TEG posed a dilemma: (i) administer FFP and vitamin-K to prevent bleeding or (ii) anti-coagulate to protect valves. Heparin was administered with serial TEGs for coagulation monitoring. Surgery was uneventful and heparin switched to warfarin on the third postoperative day. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC530 A Case of Succinylcholine Induced Bronchospasm Kara Siegrist, M.D., Shannon Kilkelly, D.O., Vanderbilt University, Nashville, TN Our case was a 24 year-old male who presented for irrigation and debridement of a leg wound. Anesthesia was induced by rapid sequence with propofol lidocaine fentanyl and succinylcholine. Immediately post-induction and intubation it was noted that the patient had increasing peak airway pressures and oxygen desaturation. Bronchospasm was suspected and treated with multimodal therapy eventually broken with volatile anesthetic and epinephrine. Bronchoscopy revealed copious bronchorrhea. Succinylcholine is believed to be the trigger for this patient's bronchospasm due to the large muscarinic component of the bronchorrhea. Succinylcholine induced bronchospasm is described in the literature though no recent cases have been reported. Sunday, October 13 3:00 PM - 4:30 PM FA MC531 Management of Brugada Syndrome in Non-Cardiac Surgery Jonathan Silva, M.D., Baylor College of Medicine, Houston, TX Brugada syndrome is a hereditary arrhythmia that occurs from a loss of function of sodium channels. It is characterized by ST-elevation in leads V1-V3 on ECG in patients with a structurally normal heart. A transmural gradient between the epicardium and endocardium results in ST-elevation and may lead to ventricular arrhythmias. The anesthesiologist must be aware of the drugs that exacerbate Brugada syndrome including beta blockers alpha agonists calcium channel blockers and certain local anesthetics. Propofol and volatile anesthetics should be used with caution. Achieving adequate pain control normothermia normocapnia and glucose and electrolyte balance may also reduce risk of tachyarrhythmias. Sunday, October 13 3:00 PM - 4:30 PM FA MC532 Difficult Airway Management in a Patient With Huge Scalp Tumor: A Case Report Marco Silvestrini, M.D., Victor Cardona, M.D., Dimaris Dominguez, M.D., University of Puerto Rico, San Juan, PR Case of a 29-year-old female patient with past medical history of bronchial asthma and atopic dermatitis allergic to aspirin presented with a slow growing scalp mass for excision. Head CT with tridimensional construction showed a highly vascular mass measuring 15.5cm x 15cm x 17.6cm. Due to the scalp mass dimensions the patient was unable to lay flat at the OR table. For the airway management an awake anterograde fiberoptic intubation was performed with the patient in fully sitting position. A comprehensive literature review revealed no similar cases have been reported in Puerto Rico and the United States. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC533 Unexpected Hemodynamic Changes in a Case of Metastatic Ovarian Carcinoma. Asha Singh, M.D., Ursula Galway, M.D., The Cleveland Clinic Foundation, Cleveland, OH 54-year-old female with PMH of HTN and Hyperglycemia diagnosed with ovarian carcinoma with Omental caking and Adrenal metastasis scheduled for Ex-lap BSO Omentectomy and Adrenal mass removal. PreInduction Epidural placement was complicated by Bradycardia and vasovagal symptoms treatment with Glycopyrrolate and Ephedrine lead to Hypertension and transient SVT. Adrenal resection was complicated by Hypertensive crisis treated with NTG Esmolol and Labetalol. After Adrenalectomy she had refractory hypotension requiring high dose of Norepinephrine Vasopressin IV fluids and ICU admission. Vasopressors were weaned off on POD # 2 and patient was extubated. Later Adrenal mass was diagnosed as Pheochromocytoma. Sunday, October 13 3:00 PM - 4:30 PM FA MC534 Avoiding Perioperative Complications in Patient With History of Ross Procedure Undergoing NonCardiac Surgery Gurbinder Singh, D.O., Sherif Zaky, M.D., Ph.D., Cleveland Clinic, Cleveland, OH Ross procedure replaces defective aortic valve with patient's own pulmonic valve and pulmonic valve is substituted with homograft. We describe intraoperative management of long-term complications resulting from this procedure. Most common complications include aortic and homograft regurgitation. A 63-year-old gentleman with history of Ross procedure performed 16 years ago underwent revision of hip arthroplasty. We placed invasive monitors including pre-induction arterial line central venous catheter and transesophageal echocardiogram to monitor hemodynamics and myocardial depression. We used Etomidate Rocuronium Fentanyl and Isoflurane to maintain forward flow without causing bradycardia or increasing systemic vascular resistance. Patient underwent surgery without complications. Sunday, October 13 3:00 PM - 4:30 PM FA MC535 The Role of Complement Activation in the Early Stages of Trauma Alexander Sinofsky, M.D., Corey Scher, M.D., NYU Langone Medical Center, New York, NY A 48-year-old male presenting with an abdominal gunshot was taken to the OR for ex-laparotomy. The patient showed signs of complement activation; he developed refractory hypotension and unresponsive to crystalloids/colloids and disordered coagulation. His BP was ultimately controlled by vasopressors and massive blood transfusion protocol. The patient developed ARDS and had a prolonged stay in the SICU. There arenno drugs available that could have controlled compliment activation and hypertonic saline 7% which has been shown to be beneficial in trauma was not available at our institution. There is likely a future role for complement inhibitors in an anesthesiologists' hands. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC536 A Simple Nasal Mask Improved Oxygenation in a Morbidly Obese Patient With Obstructive Sleep Apnea under Propofol Sedation During Upper GI Endoscopy for Post-Gastric Banding Gastric Outlet Obstruction Sameet Syed, M.D., Heather Skiff, D.O., Andy Burr, D.O., Rose Alloteh, M.D., James Tse, M.D., Ph.D., UMDNJ-Robert Wood Johnson Medical School, New Brunswick, NJ A 40-year-old 5'10 360 lb BMI 52 kg/m2 male with OSA was scheduled for EGD with dilation of gastric outlet obstruction. He was NPO for 4 days since gastric banding. After pre-oxygenated with a nasal mask using an infant mask O2 saturation increased from 95% to 100%. Pop-off valve was closed to provide continuous flow of O2 (6 L/min) and air (2 L/min). Deep sedation was induced with small boluses of propofol (total 150 mg) and maintained with infusion (150 mcg/kg/min). He maintained spontaneous respiration and 99-100% O2 saturation throughout with FiO2 of 0.7-0.8. He tolerated the procedure well. Sunday, October 13 3:00 PM - 4:30 PM FA MC537 Cardiac Arrest in an Elderly Patient With Severe Aortic Stenosis Having Occiput-C4 Decompression and Fusion Karen Slocum, M.D., M.P.H., Christopher Jackson, M.D., George Washington University, Washington, DC An 80-year-old male presents for occiput-C4 decompression and fusion due to cervical spinal cord compression. His past medical history is significant for severe aortic stenosis myocardial infarction and atrial fibrillation. Surgery is in the prone position with approximately 2 liters of blood loss requiring blood transfusion and a phenylephrine drip. At the end of the case upon turning the patient to the supine position blood pressure and pulse can no longer be attained and CPR is initiated with success. Patient is transferred to the ICU where he is treated for hypotension and discharged home 3 weeks later. Sunday, October 13 3:00 PM - 4:30 PM FA MC538 Anesthetic Concerns in a Patient With Mitochondrial Myopathy Mark Smeltzer, M.D., Lois Connolly, M.D., Medical College of Wisconsin, Milwaukee, WI 68-year-old female with history of ESRD T2DM HTN and mitochondrial myopathy presented for a kidney transplant. She was maintained on D5/0.45 NS the night prior to surgery. Utilizing standard ASA monitoring induction was accomplished with lidocaine 5mg IV propofol 100mg IV fentanyl 100mcg IV and cisatracurium 0.15mg/kg IV. Anesthesia was maintained with desflurane. Maintenance of neuromuscular blockade was achieved with a cisatracurium infusion at 1mcg/kg/min and blockade was reversed with glycopyrrolate 0.01mg/kg IV and neostigmine 0.07mg/kg IV after completion of the procedure. The patient was transported intubated to the PACU and placed on pressure support ventilation until meeting extubation criteria. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC539 Severe Hypotension in a Patient With a High Spinal Cord Injury: Is Methyl Methacrylate the Culprit? Elizabeth Smith, M.D., University of Louisville, Louisville, KY There are many causes of intraoperative hypotension in chronic spinal cord injury patients undergoing orthopedic procedures. We present a case of an 18-year-old female with a 1 year history of paraplegia resulting from T3 spinal cord injury after a motor vehicle accident who returned to the operating room with an infected femurrod. Intraoperatively the patient developed sudden severe hypotension. Various diagnoses and treatment strategies will be discussed in presentation of this case including differential diagnosis of hypotension in the chronic spinal cord injury patient which in our case included methyl methacrylate toxicity pulmonary embolus and hemorrhage. Sunday, October 13 3:00 PM - 4:30 PM FA MC540 The Challenges of Adult Onset Acromegaly Michale Sofer, M.D., Arthur Atchabahian, M.D., NYU Langone Medical Center, New York, NY A 50-year-old male with acromegaly presented for left TKR. A previous anesthetic necessitated emergent tracheostomy. Spinal anesthesia was challenging. Sedation resulted in airway obstruction and airways were unhelpful. Obstruction resolved with jaw thrust. Despite femoral and spinal block tourniquet pain appeared after 80 minutes. The procedure could be completed without general anesthesia. The patient underwent a washout to evacuate a hematoma 10 days later. Despite numerous attempts the spinal could not be performed. Femoral and sciatic blocks with minimal sedation were initially effective but as airway obstruction worsened an LMA was inserted with good results. Recovery was uneventful. Sunday, October 13 3:00 PM - 4:30 PM FA MC541 Difficult Airway Resulting From Unusual Laryngeal Pathology: A Review of Management Strategies and Diagnostic Modalities Che Solla, M.D., Walter Reed National Military Medical Center, Bethesda, MD, Fernando Resano, M.D., Medstar Washington Hospital Center, Washington, DC 88-year-old male undergoing trans-catheter aortic valve replacement. Following induction several endotracheal tubes (ETT) of different diameters were attempted unsuccessfully. A fiberoptic laryngoscopy revealed left vocal cord palsy. A computerized tomography scan revealed a calcified Teflon granuloma within the left vocal cord and a circular orifice with a diameter of 7 mm towards the posterior commissure. Because of the unyielding pathology towards the middle of the vocal cords a 5.5 mm ETT was successfully placed by maintaining the tube against the vocal cords and gently flexing the head to advance the tube through the posterior orifice. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM FA MC542 Retroperitoneal Tumor Resection Complicated by Pulmonary Embolism Carlos Soto, NYU Medical Center, New York, NY A 77-year-old male presented for resection of a retroperitoneal leiomyosarcoma extending into the infra-hepatic IVC. After an hour of dissection significant bleeding and hypotension developed; an elevated ACT suggested coagulopathy. Vasopressors and massive fluid/blood product resuscitation were initiated. After another hour the patient developed high peak and plateau airway pressures desaturation and a drop in EtCO2. TEE demonstrated a dilated RV and a mass in the right pulmonary artery consistent with pulmonary embolism. Dramatic hypotension was treated with brief chest compressions and epinephrine. After transport to the PACU all life support was discontinued per family request. Sunday, October 13 3:00 PM - 4:30 PM FA MC543 A Failed Attempt to Place a Carotid Stent Carlos Soto, NYU Medical Center, New York, NY A 78-year-old woman with severe carotid stenosis presented for carotid stent placement. She had a history of multiple TIAs as well as severe hypertension DM2 PVD and CKD. The patient expressed significant anxiety but received no anxiolytics per surgeon request in order to accurately monitor any changes in mental status during the procedure. Blood pressure was difficult to control with multiple anti-hypertensive meds with systolic in the 220's. An episode of agitation and movement was shortly followed by dysarthria facial droop hemiparesis and episodes of bradycardia. A stroke code was called. Sunday, October 13 3:00 PM - 4:30 PM FA MC544 Partial Hepatectomy Complicated by Hyperkalemia Associated Cardiac Arrest Liza Starecki, M.D., Wojciech Reiss, M.D., St. Lukes - Roosevelt Hospital, New York, NY A 39-year-old female with a giant cavernous hemangioma of liver presented for right hepatic lobectomy. The procedure was complicated by blood loss requiring massive transfusion. After 6 units of pRBC were transfused over one hour patient experienced a transfusion-associated hyperkalemic cardiac arrest. The EKG showed a sine wave which rapidly progressed to ventricular tachycardia and asystole. An ABG sample taken 3 minutes before any EKG changes revealed a potassium level of 9.3 mEQ/ dL. The hyperkalemia was managed with epinephrine insulin glucose and calcium and the patient returned to sinus rhythm. Sunday, October 13 3:00 PM - 4:30 PM CA MC545 Use of the Lariat Device for Left Atrial Appendage Closure Suzanne Kellman, M.D., Megan Lanigan, M.D., Mark Chaney, M.D., The University of Chicago, Chicago, IL 73F with atrial fibrillation (AF) whose warfarin was stopped secondary to GI bleeding presents for percutaneous left atrial appendage (LAA) exclusion. AF increases risk of embolic stroke with most thrombi originating in the LAA. Exclusion of this appendage may reduce stroke risk in patients with contraindications to oral anticoagulation. The Lariat procedure in which an exclusion device is threaded from the subxiphoid into the pericardium to snare the LAA is a new technique with unique anesthetic Copyright © 2013 American Society of Anesthesiologists considerations. In comparison with other LAA exclusion procedures it has a higher success rate and does not require continuation of anticoagulation post-operatively. Sunday, October 13 3:00 PM - 4:30 PM CA MC546 Severe Bronchospasm With Unilateral Right Main Bronchus Collapse and Tracheal Swelling During Ross Procedure in a 28-year-old Male Divya Kestur Rajasekhar, M.D., Trevor Banack, M.D., Yale University School of Medicine, New Haven, CT 28-year-old M with severe AR presented for AVR. PMH includes: morbid obesity hypertension childhood asthma and current smoker. CPB time was 257minutes. ABG after CPB was 7.37/344/43/ 95/24.9. Protamine and FFP/platelets were administered. After starting platelets/FFP the patient became difficult to ventilate peak airway pressure increased blood pressure decreased and ABG 7.21/49/63/78/25. FOB revealed a collapsed/swollen trachea and right bronchus beyond the ETT. Transfusion reaction was suspected. Blood products were stopped and medications administered: IV steroids/epinephrine infusion/Benadryl/inhaled steroids/epinephrine/inhaled albuterol. After 1.5hours airway swelling decreased and ABG improved 7.33/40/95/20.5/98.The patient was brought to CTICU stable. Sunday, October 13 3:00 PM - 4:30 PM CA MC547 Fixing Broken Hearts With Saline Ansar Khan, M.D., University of Maryland Medical Center, Baltimore, MD An anxious 14-year-old male with dilated cardiomyopathy presented to the OR secondary to acute exacerbation of his biventricular failure. Commonly used drugs including propofol etomidate dobutamine and calcium chloride were in critically low supply or not available secondary to national shortage. Using the IABP low dose midazolam and fentanyl with phenylephrine flush were used to safely induce anesthesia. A BIVAD was successfully placed as a bridge to heart transplant. This case illustrates how national drug shortages are forcing anesthesiologists to develop novel and potentially precarious anesthetic plans for once practical and predictable induction maintenance and emergence. Sunday, October 13 3:00 PM - 4:30 PM CA MC548 Such a Big Heart. Or is it an Aneurysm? Swapnil Khoche, Mahesh Sardesai, M.D., Sudhakar Yennam Reddy, M.B. B.S., University of Pittsburgh Medical Center, Pittsburgh, PA A 69-year-old female was scheduled for resection of a ventricular aneurysm related to recent inferior MI. Her reported EF was 10%. After uneventful induction of general anesthesia transesophageal echocardiography revealed a larger basal posterior aneurysm (6.2 x 5.3cm) with otherwise good ventricular wall motion moderate mitral regurgitation and no left ventricular thrombus. The patient underwent the operation uneventfully. Aside from the unusual size and location of the aneurysm our case highlights the utility of real time 3D echocardiography in structural and functional quantification during complex and dynamic conditions during the perioperative period Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM CA MC549 3D Echocardiography During Right Heart Intracardiac Thromboembolectomy Eugene Kim, M.D., Christopher Tam, M.D., Sandeep Gupta, M.D., Igor Izrailtyan, M.D., Stony Brook Medicine, Stony Brook, NY Although no evidence-based management guidelines for right heart intracardiac thromboemboli exist surgical thromboembolectomy remains as a valuable option for certain patients. We present an 85-yearold female referred to our institution after outpatient echocardiography diagnosed a large mobile thrombus originating in the inferior vena cava extending into the right atrium and prolapsing through the tricuspid valve. Following extraction of the thrombus intraoperative 3D echocardiography was utilized to guide decision-making for right pulmonary artery thromboembolectomy. Sunday, October 13 3:00 PM - 4:30 PM CA MC550 Difficulty Achieving Asystole When the Procedure Requires a Temporary Cessation of Pulsatility Sang Kim, M.D., Andrew Leibowitz, M.D., Icahn School of Medicine at Mount Sinai, New York, NY 83-year-old male sustained an endoleak after endovascular repair of his infrarenal abdominal aortic aneurysm (AAA) and presented for an open AAA banding procedure. Surgical technique required transient (5 seconds) asystole. Escalating bolus doses of adenosine of 6 12 18 and 24 mgs were ineffective. A bolus of adenosine 24 mg with esmolol 45 mg yielded a brief episode of bradycardia and then a combined bolus dose of adenosine 30 mg with esmolol 60 mg resulted in asystole sufficient to accomplish the repair. The history of the use of adenosine in endovascular surgery will be explored in this presentation. Sunday, October 13 3:00 PM - 4:30 PM CA MC551 Left Ventricular Outflow Tract Obstruction With Systolic Anterior Motion of the Mitral Valve Diagnosed by Transesophageal Echocardiography in Refractory Hypotensive Patient After Heart Transplantation Tae Kyong Kim, M.D., Jeong Jin Min, Yunseok Jeon, Deok Man Hong, Jae-Hyon Bahk, Seoul National University Hospital, Seoul, South Korea A 44-year-old man presented for urgent heart transplantation due to dilated cardiomyopathy which rapidly progressed to multi-organ failure. Transthoracic echocardiography revealed pulmonary hypertension and global hypokinesia with ejection fraction of 20%. Heart transplantation was performed under cardiopulmonary bypass (CPB) and separation from CPB was tried using infusion of dobutamine and milrinone. However hypotension and tachycardia aggravated and transesophageal echocardiography showed left ventricular outflow tract obstruction (LVOTO) with systolic anterior motion of the mitral valve. After discontinuation of dobutamine and administration of norepinephrine LVOTO was improved and his blood pressure was restored. CPB was weaned successfully.

An arterial line was inserted anesthesia was induced the airway was secured and central lines were placed. A thoracotomy was preformed and cardiopulmonary bypass was instituted due to pulmonary artery hemorrhage. The donor lung was reperfused and CPB was weaned. Massive transfusion continued for persistent mediastinal hemorrhage so the chest was packed. An ICU ventilator was instituted and the renal transplant began. Mild hypoxia persisted throughout the renal transplant. The chest was closed after hemostasis was deemed adequate. The patient was transferred to the ICU. Sunday, October 13 3:00 PM - 4:30 PM CA MC553 Tick Associated Adult Onset Anaphylaxis and its Impact for CPB Amanda Kleiman, M.D., Keith Littlewood, M.D., Danja Groves, M.D., University of Virginia, Charlottesville, VA We present two separate cases in which patients with known tick bite associated delayed anaphylaxis to red meat presented for cardiopulmonary bypass. In each case the decision was made to proceed with the use of heparin prior to initiation of bypass and varying degrees of prophylaxis were used. Despite prophylaxis including dexamethasone and H1 blockers one patient exhibited a severe anaphylactic reaction. With the addition of an H2 blocker for the 2nd patient the patient exhibited only a moderate rash. Sunday, October 13 3:00 PM - 4:30 PM CA MC554 Acute Aortic Dissection Requiring CPB and DHCA Scott Klier, D.O., Arjang Khorasani, M.D., Advocate Illinois Masonic Medical Center, Chicago, IL We present the case of a 70-year-old female who presented with an acute ascending aortic dissection requiring emergent repair. This repair was accomplished using femoral-femoral cardiopulmonary bypass and deep hypothermic circulatory arrest to ensure adequate neuroprotection while antegrade vascular flow was suspended. A coordinated effort between the surgeon anesthesiologist and perfusionist allowed for successful surgical repair and avoidance of the multiple complications that are frequently associated with this surgery. The patient had an uneventful post-operative course and was able to be discharged home within one week of her surgery. Sunday, October 13 3:00 PM - 4:30 PM CA MC555 Managing the Hypercoagulable Bypass Patient Natalia Klosak, M.D., Albert Robinson, M.D., University of Florida, Gainesville, FL A 24-year-old female with known Antithrombin III deficiency presented two weeks post-partum with venous thromboembolism. The patient underwent bilateral iliac and caval thrombectomy and experienced post-operative dyspnea chest pain and hypotension. Bedside TTE in the ICU revealed severe RV dysfunction following which the patient arrested and received large dose inotropic support and Copyright © 2013 American Society of Anesthesiologists continuous CPR en route to OR. She was found to have a massive saddle embolus and required pulmonary embolectomy and RVAD placement on cardiopulmonary bypass. Due to her hypercoagulable status unconventional management of anticoagulation was required with excess heparin and FFP to maintain the bypass circuit. Sunday, October 13 3:00 PM - 4:30 PM CA MC556 Approach to Medical and Surgical Management of Aortic Insufficiency in Patients With Heartmate II LVAD: A Case Report Vibhuti Kowluru, M.D., Jeremy Poppers, M.D., Columbia University- New York Presbyterian Hospital, New York, NY Patient is a 75-year-old man with NIDCM rheumatic heart disease with moderate AS/MR afib AICD who underwent Heartmate II LVAD insertion with MV ring as Destination Therapy. His post VAD course was notable for right heart failure and recurrent GI bleeds requiring suspension of anticoagulation. Following patient developed device thrombosis requiring LVAD exchange. Consequently he developed dyspnea on exertion and was found to have severe aortic insufficiency. Given elevated creatinine and inability to increase LVAD speeds due to severe hemolysis patient underwent Amplatzer closure of aortic valve. Approach to aortic insufficiency in patients with Heartmate II LVAD is discussed here. Sunday, October 13 3:00 PM - 4:30 PM CA MC557 Broken Hearted: A Case Presentation of Atrioventricular Disruption Following Aortic and Mitral Valve Replacement Dinesh Kurian, M.D., MBA, Arun Jayaraman, M.D., Ph.D., Jacob Klapper, M.D., Jeffery Gaca, M.D., Mark Stafford-Smith, M.D., Duke University, Durham, NC Atrioventricular disruption (AVD) is a devastating complication of cardiac surgery. We present a case of AVD in a patient undergoing aortic and mitral valve replacement. In addition to severe aortic and mitral stenosis TEE identified mitral annular calcification requiring debridement. Following separation from cardiopulmonary bypass bleeding was noted from the posterior aspect of the heart. It was judged that the patient would not tolerate return to bypass for surgical repair prompting non-surgical attempts to treat AVD. Despite these efforts the patient died eight hours after surgery. In this case we discuss the risk factors diagnosis and treatment of AVD. Sunday, October 13 3:00 PM - 4:30 PM CA MC558 Unstable Supraventricular Tachycardia Due to Prescription Stimulant Use in an Adult Patient With ADHD Robert LaCivita, Giuseppe Trunfio, M.D., Maimonides Medical Center, Brooklyn, NY, Christopher Ovanez, M.P.H., St. George's University School of Medicine, Grenada A 51-year-old woman with adult attention deficit hyperactivity disorder on multiple stimulant and psychotropic medications presented for elective total hip arthoplasty. After the induction of general anesthesia and positioning in the absence of any surgical stimulation the patient unexpectedly and abruptly developed unstable SVT . She was electrically cardioverted returned to normal sinus rhythm and surgery was cancelled. Post operative work up including echocardiogram EKG and lab work was unremarkable. It was hypothesized that the paroxysmal SVT was likely attributable to her use of Copyright © 2013 American Society of Anesthesiologists Dextroamphetamine/Amphetamine in association with other commonly prescribed psychotropic medications. Sunday, October 13 3:00 PM - 4:30 PM CA MC559 Case of Prolonged QT Type 3 Revealed Under General Anesthesia After Episode of Sudden Cardiac Arrest in a 10-year-old Lisa Lee, M.D., Drexel University College of Medicine, Philadelphia, PA A 10-year-old female presented after collapsing after running. CPR was initiated by school staff and she was successfully defibrillated with AED. There was no family history of sudden cardiac death. Exercise stress testing showed no exercise-induced arrhythmias. Cardiac MRI and echocardiography were normal. An ICD was deemed necessary as the cause of her ventricular fibrillation had not been discovered. During ICD implantation under general anesthesia her QTc became extraordinarily long. This had not been noted previously at rest or with exercise. A diagnosis of Long QT Type 3 was made. No further episodes of prolonged QT were noted post-procedure. Sunday, October 13 3:00 PM - 4:30 PM CA MC560 Implant of Syncardia® Total Artificial Heart in an ACHD Patient With an LVAD Erica Lin, M.D., Renee Kreeger, M.D., Lori Aronson, M.D., Cincinnati Children's Hospital Medical Center, Cincinnati, OH Advancements in congenital heart disease care have led to improved survival and the evolution of a unique patient population: the adult with congenital heart disease (ACHD). As a referral center for ACHD care within a pediatric hospital setting and with an expertise in ventricular assist devices (VAD) our team assumed care of a 34-year-old ACHD patient with right heart failure and an implanted LVAD. The perioperative experience surrounding her conversion to a biventricular device epitomizes the challenges faced by a multidisciplinary team when caring for an ACHD patient who presents with fulminant cardiac failure. Sunday, October 13 3:00 PM - 4:30 PM CA MC561 Cardiac Amyloidosis and Anesthetic Management for Cardiac Surgery John Liu, M.D., Lynn Belliveau, D.O., Kalpana Tyagaraj, M.D., Maimonides Medical Center, Brooklyn, NY 74-year-old male with medical history of prostate cancer HTN CAD s/p CABG and stents presented for tricuspic valve replacement. Most recent cardiac imaging was suggestive of cardiac amyloidosis which was not noted at the first cardiac surgery 8 years prior. Physical exam EKG and intraop TEE showed characteristic findings of amyloid cardiomyopathy. Patient presented with signs and symptoms of right heart failure. Intraoperative TEE showed severe right and left heart failure severe TR and MR. The perioperative management of the patient was complicated and required multiple vasopressors inotropes and inhaled pulmonary vasodilators to wean from cardiopulmonary bypass Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM CA MC562 Orthotopic Cardiac Transplantation After a Post-Infarction Ventricular Septal Rupture Pingle Reddy, M.D., Geoffrey Lively, Vigneshwar Kasirajan, M.D., Virginia Commonwealth University, Richmond, VA This is a 44-year-old male who initially presented to an outside hospital with a massive inferior wall STEMI. During catheterization he developed cardiogenic shock and required emergent placement of ECMO. At the time the patient was found to have a large ventricular septal defect (VSD) secondary to ventricular septal rupture (VSR). After a complicated hospital course including a failed VSD closure the patient was transported to our hospital for further care. Approximately three weeks later a Total Artificial Heart was placed for bridge to transplantation which occurred five months after the initial injury. Sunday, October 13 3:00 PM - 4:30 PM CA MC563 Anesthetic Management of a 40-Year-Old With Uncorrected Tetralogy of Fallot Receiving Radiofrequency Ablation for Metastatic GI Stromal Tumors Nathaniel Loo, M.D., Jonathan Gal, M.D., Mount Sinai Hospital, New York, NY The most common cyanotic congenital heart defect tetralogy of fallot (TOF) results in adverse cardiopulmonary changes. Early surgical treatment of TOF attenuates long term effects of hypoxia and cyanosis from shunting on cardiac remodeling. Only 3% of uncorrected TOF patients survive past 40 years and these surviving patients pose multiple anesthetic challenges. This 40-year-old patient with uncorrected TOF underwent radiofrequency ablation for metastatic GI stromal tumors. Challenges in anesthetic management from the severity of his underlying right ventricular hypertrophy pulmonary stenosis and intraoperative shunting are discussed. Sunday, October 13 3:00 PM - 4:30 PM CA MC564 Aortic Valve Replacememnt-Bentall Procedure Complicated by Profound Vasoplegia and Transfusion Related Lung Injury During Cardiopulmonary Bypass Requiring Methylene Blue Infusion and IntraAortic Balloon Pump Insertion Antonio Hernandez Conte, M.D., MBA, Nir Maghen, M.D., Ali Khoynezhad, M.D., Cedars-Sinai Medical Center, Los Angeles, CA A 55-year-old -female ASA 4 with a past medical history of severe aortic stenosis and ascending aortic aneurysm presented for an elective aortic valve replacement and Bentall procedure. After initiating CBP the patient was transfused with autologous and donor directed packed red blood cells. Almost immediately after transfusion was initiated the patient developed severe hypotension and copious pulmonary secretions and required large doses of vasopressin epinephrine and norepinephrine. Differential diagnoses included anaphylactoid reaction or TRALI. Persistent systolic and diastolic hypotension required use of methylene blue during CPB and insertion of an intraaortic balloon pump in order to wean off CPB. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM CA MC565 Aortic Valve Replacement in a Patient With Malignant Hyperthermia Tammy Mai, D.O., John Medley, M.D., Univeristy of Missouri, Columbia, MO Patient is a 71-year-old female with a history of malignant hyperthermia and severe aortic stenosis scheduled for an aortic valve replacement. Glidescope was used for anticipated difficult airway and hemodynamic goals of aortic stenosis were maintained throughout surgery. Anesthetic plan included avoiding triggering agents volatile anesthetics were removed from anesthesia machine CO2 absorbent canister was changed anesthesia machine was flushed with O2 at 10L/min for 20 minutes before start of case and TIVA was used for anesthesia with dexmedetomidine infusion for maintenance. Patient underwent an uneventful surgery and post op course and was discharged on post-op day 15. Sunday, October 13 3:00 PM - 4:30 PM CA MC566 Pulmonary Embolism in a Patient Undergoing CABG Tammy Mai, D.O., Mitch McKamey, D.O., Univeristy of Missouri, Columbia, MO 62-year-old female transferred from an outside hospital with severe triple vessel CAD and intra-aortic balloon pump for post infarction angina scheduled for CABG. After completion of protamine the patient became unstable with pulmonary hypertension hemorrhage and cardiogenic shock requiring inotropic support and return to bypass. A bronchial blocker was placed and the patient was taken to IR lab. Imaging revealed an aneurysm in the bronchial artery segment to the right lower lobe and a large embolus to the right main pulmonary artery. She was returned to the OR for embolectomy but continued to have hemodynamic deterioration. Sunday, October 13 3:00 PM - 4:30 PM CA MC567 A Patient With Severe Asthma and Moderate Aortic insufficiency From Bicuspid Valve for Laparoscopic Inguinal Hernia Surgery Bryan Marchant, M.D., Chuanyao Tong, M.D., Sandy An, B.S., Nichole Taylor, D.O., Wake Forest, Winston-Salem, NC Despite being minimal invasive and allowing for faster recovery laparoscopic CO2 insufflation places a significant strain on the cardiovascular and pulmonary systems. A morbidly obese patient with bicuspid induced aortic insufficiency and ascending aneurysm CAD severe asthma and other comorbidities is scheduled for redo laparoscopic inguinal hernia surgery. During the presentation we will discuss the preanesthesia evaluation-the discrepency between the lab tests and history acquiring and physical examination; form a practical anesthesia plan and the outcome of the anesthesia care. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM CA MC568 The Pitfalls of Transthoracic Echocardiography in Evaluation of Endocarditis: A Case Report of Artifactual Mitral Stenosis Rebecca Margolis, D.O., Sarah Armour, M.D., Mark Nelson, M.D., Virginia Commonwealth University, Richmond, VA We present a patient with a history of liver and renal transplant heparin induced-thrombocytopenia and endocarditis who presented for a third time mitral valve replacement after transthoracic echocardiogram demonstrated thrombus causing severe mitral stenosis. Intraoperative transesophageal echocardiography revealed that the presumed thrombus was in fact an acoustic shadow. Due to this finding the management of the patient was dramatically altered and the case was cancelled. This case highlights the superiority of TEE over TTE for the detection of complications related to endocarditis and the inherent pitfalls of TTE such as acoustic shadowing and poor acoustic windows Sunday, October 13 3:00 PM - 4:30 PM CA MC569 Rare Ventricular Wall Mass With RVOT Obstruction Eric Massey, WVU, Morgantown, WV Patient is a 41-year-old female with no pertinent PMH who presented with shortness breath mild chest discomfort and complaints of malaise and worsening cough. CT scan of the chest revealed a questionable intraventricular mass. Cardiac work-up included transesophageal echocardiogram and cardiac MRI which confirmed the presence of cardiac tumor with involvement of the right atrium and right ventricle. Endomyocardial biopsy returned as a likely rhabdomyoma. Cardiac function ejection fraction chamber pressures and coronary arteries were normal at rest. This discussion will focus on the anesthetic management and implications of a RVOT mass. Sunday, October 13 3:00 PM - 4:30 PM CA MC570 Diagnosis and Management of Incidental Aortic Dissection During Bilateral Lung Transplantation With Cardiopulmonary Bypass Michael Mathis, M.D., Matthew Caldwell, M.D., University of Michigan, Ann Arbor, MI We describe a 29-year-old male with medically refractory cystic fibrosis presenting for double-lung transplant. After induction of general anesthesia and initiating mechanical ventilation worsening pulmonary hypertension prompted initiating cardiopulmonary bypass. The surgery proceeded uneventfully; however upon weaning from cardiopulmonary bypass and decannulation intraoperative transesophageal echocardiography demonstrated a previously undiagnosed retrograde Type B aortic dissection. An intraoperative cardiac surgery consult was obtained and due to concern for retrograde extension the patient underwent an ascending aortic arch replacement. The aortic arch replacement proceeded as planned and upon completion the patient was transferred to the intensive care unit in stable but critical condition. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM CA MC571 Metastatic Leiomyosarcoma Compressing the Left Ventricle Sharon McCartney, M.D., George Whitener, M.D., Duke University, Durham, NC A 44-year-old female who previously underwent total abdominal hysterectomy for uterine leimyosarcoma developed a left lower lung metastasis measuring 22 x 14 x 10cm. This tumor extruded outside of her skin on the lateral border and compressed her left ventricle on the medial border. She had poor functional status including dyspnea and chest pain with minimal exertion. We describe the intraoperative anesthetic management of her left lower lobectomy excision of seven ribs pericardium and left hemidiaphragm as well as reconstruction of the left hemidiaphragm pericardium and chest wall. We also describe the patient's postoperative course and analgesia management. Sunday, October 13 3:00 PM - 4:30 PM CA MC572 Left Ventricular Perforation After Transcatheter Aortic Valve Replacement (TAVR) Deployment Sharon McCartney, M.D., Arun Jayaraman, M.D., George Whitener, M.D., Duke University, Durham, NC A 73-year-old female with severe aortic stenosis coronary artery disease status post prior coronary artery bypass surgery hypertension and peripheral vascular disease had NYHA class III symtpoms of dyspnea and chest pain with minimal exertion. Due to small caliber femoral vessels she underwent transcatheter aortic valve replacement (TAVR) with a partial sternotomy and direct aortic approach. After deployment of a 26 mm Medtronic CoreValve the patient developed profound hypotension refractory to pharmacologic support. Transesophageal echocardiography revealed an expanding hemorrhagic pericardial effusion and large left ventricular rupture. We discuss this case as a complication of TAVR. Sunday, October 13 3:00 PM - 4:30 PM CA MC573 Aspiration in Asymptomatic Patient With Remote History of Gastrectomy Daniel McGuire, M.D., Abraham Fura, D.O., Erika Cyr, M.D., Jeffrey Sagel, D.O., Walter Reed National Military Medical Center Bethesda, Besthesda, MD, Victor Rivera, M.D., Naval Health Clinic Cherry Point, Cherry Point, NC A 74-year-old male with remote history of esophagectomy-gastrectomy presented for coronary artery bypass graft. Surgery was complicated by an aspiration event on induction despite asymptomatic Gastroesophageal Reflux Disease H2 blocker therapy and appropriate npo status. Suction of aspirated fluids was performed and bronchoscopy revealed clean bilateral airways. Surgery was continued after serial arterial blood gasses demonstrated appropriate oxygenation; however separation from bypass was complicated by significant hypoxemia requiring inhaled nitric oxide and Airway Pressure Release Ventilation. The development of Acute Respiratory Distress in this case is presumed multifactorial to include both aspiration pneumonitis and cardiopulmonary bypass-associated lung injury. Copyright © 2013 American Society of Anesthesiologists Sunday, October 13 3:00 PM - 4:30 PM CA MC574 3D TEE Diagnosis of an Acute Atrioventricular Valve Thrombosis in a Patient With a Single Ventricle for Impella Implantation Renata Miketic, M.D., Sasha Shillcutt, M.D., Univ of Nebraska Med Ctr, Omaha, NE Mechanical valve thrombosis is a severe complication post-valve replacement. Risk factors for thrombosis include hypercoagulability blood stasis and endothelial damage. Acute mechanical valve thrombosis is a critical event with significant morbidity and mortality. Urgent diagnosis is imperative to treatment and survival. Because 3D TEE has increased spatial and temporal resolution of intra-cardial masses it has allowed cardiac anesthesiologists to expand their diagnostic capabilities. We describe the use of 3D TEE to diagnose acute valve thrombosis in a patient with a functional single ventricle who presented for Impella implantation to treat acute heart failure two weeks after mechanical tricuspid valve placement. Sunday, October 13 3:00 PM - 4:30 PM CA MC575 Hypotension on Cardiopulmonary Bypass During Closure of a Potts Shunt in an Adult Congenital Heart Disease Patient Jeffrey Moore, D.O., Mark Lischner, D.O., Richard McAffee, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA A 47-year-old female with congenital atrial septal defect ventricular septal defect hypoplastic right ventricle and a palliative Potts shunt (aorta to left pulmonary artery) presents for shunt closure and cardiac transplant. Profound hypotension occurred with the initiation of cardiopulmonary bypass despite adequate flow resistance and vasopressors. Left to right shunting across the Potts shunt was diagnosed from physiologic signs and compression of the pulmonary artery. The patient suffered anoxic brain injury but fortunately recovered to near baseline status. Sunday, October 13 3:00 PM - 4:30 PM CA MC576 Impossible to Induce Safely - SVC Narrowing With Adrenal Insufficiency? Allison Moriarty, M.D., Daniel Sizemore, M.D., West Virginia University, Morgantown, WV A 33-year-old female was admitted to our hospital with bradycardia and urosepsis. The bradycardia required placement of a temporary transvenous pacemaker. After stabilization she presented to the operating room for epicardial pacemaker lead placement via left thoracotomy. Permanent transvenous leads were not being attempted due to chronic SVC narrowing observed on CT scan. She had a history of a gunshot wound to the head with subsequent stroke seizures and hypopituitarism. Her medications included hydrocortisone 30mg qAM and 20mg qPM DDAVP and synthroid. We discuss anesthetic planning and induction in a pacemaker-dependent patient with SVC narrowing and adrenal insufficiency.

We utilized an inhalation induction using sevoflurane in order to maintain spontaneous ventilation with assistance after which a bolus of remifentanil and an infusion of propofol were started. The patient's airway was surrendered to the otolaryngologist who intubated using direct laryngoscopy and a 5.0 cuffed standard endotracheal tube. We utilized periods of apnea at two minute intervals after which the patient was mask ventilated to an end tidal oxygen if 90%. The patient was dilated up to a size 7.5 endotracheal tube. Monday, October 14 8:00 AM - 9:30 AM AM MC578 Anesthetic Management of a Patient With a Cardiac Life-Vest Undergoing a TURP Procedure Alec Lawrence, M.D., Kenneth Moran, M.D., The Ohio State University Wexner Medical Center, Columbus, OH The cardiac LifeVest is a wearable external defibrillator used for patients at high risk for sudden cardiac arrest who are not currently candidates for implantable ICD placement such as unknown permanent risk or infection. This case involved a patient with severe LV systolic dysfunction and a LifeVest due to an infected sternal wound that was scheduled to undergo a TURP procedure. We will discuss the anesthetic considerations including how the vest functions whether it should be continued intraoperatively and the implications of concurrent use of electrosurgical units. Monday, October 14 8:00 AM - 9:30 AM AM MC579 Abnormal EKG in a Patient With History of Substance Abuse John Lee, M.D., University of Southern California, Los Angeles, CA 24-year-old male with history of substance abuse and unknown abnormal cardiac rhythm scheduled for ankle fracture ORIF. On arrival to OR patient begins having multiple PVCs while in NSR. The patient becomes anxious and tachycardic NSR becomes solely PVCs resembling Vtach or an accessory pathway rhythm. Still the patient is hemodynamically stable. Lidocaine is given and has no effect. Esmolol is given and NSR returns interspersed with PVCs. Intraoperatively patient continues to have a tachycardic and abnormal rhythm and esmolol is no longer effective. Patient is admitted and cardiology is consulted. Monday, October 14 8:00 AM - 9:30 AM AM MC580 The Land of the Unknown: Spinal Anesthesia in a Patient With Kennedy's Disease Brittany Maggard, M.D., Marina Varbanova, M.D., Gary Loyd, M.D., University of Louisville, Louisville, KY We are presenting a case of spermatocelectomy on a 68-year-old patient with Kennedy's disease. Kennedy's disease is a rare X-linked recessive neurodegenerative disorder of lower motor neurons Copyright © 2013 American Society of Anesthesiologists characterized by progressive proximal limb and bulbar muscular atrophy. Patients with the disease have an increased risk of spontaneous laryngospasm postoperative glottic edema and may require prolonged ventilatory support. There is no literature reporting the use of spinal anesthesia in patients with Kennedy's disease. We felt a spinal anesthetic would be a reasonable alternative for our patient who tolerated the blockade well with no delay in his postoperative recovery. Monday, October 14 8:00 AM - 9:30 AM AM MC581 Choking Patient in PACU: Airway Management of Patient With T-Tracheal Tube Tariq Malik, Atul Gupta, M.D., University of Chicago, Chicago, IL 76-year-old Polish speaking male with bladder cancer left hemiparesis hypertension subglottic/tracheal stenosis with T-tube presented for TURBT. No records were available for similar procedure done under GA previously at an outside facility. Patient refused neuraxial anesthesia. After propofol induction Ttube was switched to 7.0 cuffed endotracheal tube. At the end t-tube was replaced after multiple attempts. In PACU patient woke up combative requiring sedation. A family member brought in to help communicate with the patient pointed out that the t-tube had been placed in reverse orientation like the last time. ENT then placed the tube under bronchoscopic guidance. Monday, October 14 8:00 AM - 9:30 AM AM MC582 I've Fallen Asleep and I Can't Get Up: A Rare Complication: Conversion Disorder After General Anesthesia for Ambulatory Surgery Chawla LaToya Mason, M.D., Damien Larkins, M.D., Baylor College of Medicine, Houston, TX A 46-year-old healthy woman presented for breast biopsy. She received general anesthesia comprised of midazolam fentanyl lidocaine propofol and sevoflurane. During recovery she reported loss of motor and sensory function in bilateral extremities below level of the knees. Neurosurgery and neurology teams were immediately consulted for further evaluation that included computed tomography. No organic explanation for the patient's symptoms was found. After psychiatric evaluation a presumptive diagnosis of conversion disorder was made. At time of discharge he required a walker for ambulation assistance. Several months later she returned to the hospital for an unrelated visit with no neurologic deficits. Monday, October 14 8:00 AM - 9:30 AM AM MC583 A Successful Perioperative Management of Liver Transplantation Case With Idiopathic Pulmonary Fibrosis Takashi Matsusaki, M.D., Keishi Kawano, M.D., Norihiko Obata, M.D., Ryuji Kaku, M.D., Hiroshi Morimatsu , M.D., Okayama University Hospital, Okayama, Japan A 46-year-old female cirrhotic patient due to hepatitis of type C presented with progressive dyspnea hypoxemia and increased alveolar-arterial oxygen gradient (A-a) requiring home oxygen therapy due to Idiopathic Pulmonary Fibrosis. Her Model for End-stage Liver Disease was 16 however she also had progressive hepatocelluar carcinoma within the Milan criteria. She had received the living-donor liver transplantation from her husband. We gave her lowered her concentration of oxygen and tidal volume during the operation.

Monday, October 14 8:00 AM - 9:30 AM AM MC586 Anesthetic Management of Achondroplastic Dwarf Mayur Patel, M.D., Victor Mandoff, M.D., University of Arkansas for Medical Sciences, Little Rock, AR A 67-year-old female achondroplastic dwarf presenting with metastatic colon cancer to liver was scheduled to have segmentectomy of segment 8 of liver and cholecystectomy. Patient was 49 inches tall and weighed 40 kg. Patient appeared very anxious in preoperative holding. Smooth IV induction to facilitate intubation. Once patient stabilized 16 gauge and 14 gauge intravenous lines were inserted peripherally and in external jugular respectively. Although patient had bounding radial pulses on palpation bilaterally we had multiple failed attempts to thread arterial catheters in the radial arteries. After these failed attempts a catheter was placed in the femoral artery. Monday, October 14 8:00 AM - 9:30 AM AM MC587 Prolonged Paralysis After an Intubating Dose of Intermediate Non-Depolarzing Muscle Relaxant Thao Pham, M.D., Tara Kennedy, M.D., Silpa Goriparthi, M.D., Thomas Jefferson University Hospitals, Philadelphia, PA A healthy 40-year-old 73 kg African American female with a malignant right breast mass was scheduled for partial mastectomy. Pre-operative labs revealed a stable hemoglobin of 6.3 g/dl and normal Copyright © 2013 American Society of Anesthesiologists metabolic panel and liver function tests. 40mg (0.48mg/kg) of rocuronium was given intravenously to facilitate intubation. Two hours later the train of four was 0/4 with no post-tetanic response. Recovery of neuromuscular function did not occur until four hours after induction. We will discuss possible causes of this unique clinical predicament and the need for quantitative measurement of neuromuscular blockade even after a single dose of paralytic. Monday, October 14 8:00 AM - 9:30 AM AM MC588 Aspiration in a Patient With Delayed Gastric Emptying: What to Do When NPO Guidelines Fail? Taylor Plumer, Mercy Udoji, University of Alabama at Birmingham, Birmingham, AL 57-year-old WF with systemic sclerosis gastric bypass & esophageal dilations presents for amputation of bilateral ischemic digits. Patient brought to OR noting last PO intake 48-72hrs prior. Before RSI for GETA patient received IV ranitidine for nausea. As propofol and lidocaine were administered copious amounts of bilious emesis were noted. With head turned in trendelenburg position immediate suctioning of oropharynx returned bilious content with particulate matter. Intubation proceeded with 5cc of similar content suctioned from the endotracheal tube and an additional 2400mL of bilious content suctioned from a nasogastric tube resulting in case cancellation and hospitalization for aspiration pneumonia. Monday, October 14 8:00 AM - 9:30 AM AM MC589 Spontaneous Ventricular Fibrillation and Torsade De Pointes in an Elderly With Undiagnosed Severe Hypomagnesemia Govind Rajan, University of California Irvine, Irvine, CA, Kristin Satterfield , M.D., Maxime Cannesson , M.D., Ph.D., UCI Medical Center, Irvine, CA Acquired renal magnesium wasting due to aging and mild interstitial renal disease is increasingly being recognized. The incidence is further increased among patients with history of diabetes and those on diuretic therapy. We present a case unprovoked ventricular fibrillation and torsades de pointes in an elderly with undiagnosed severe hypomagnesemia in the immediate post operative period following wide local excision of right cheek melanoma. The discussion focusses on the importance of undiagnosed hypomagnesemia among elderly and its clinical implications in the perioperative period. Monday, October 14 8:00 AM - 9:30 AM AM MC590 Isosulfan Blue Dye Anaphylaxis Presenting as Inability to Ventilate With an LMA Heather Reed, M.D., Huong Le, M.D., Christiana Shaw, M.D., Mark Rice, M.D., University of Florida, Gainesville, FL A 44-year-old woman presented for sentinel node biopsy and segmental mastectomy. After induction an LMA was placed with adequate ventilation. Three minutes after isosulfan blue dye injection for sentinel node location ventilation became difficult. The LMA was removed and an ETT was placed easily. Twenty minutes later she became hypotensive and unresponsive to phenylephrine ephedrine and vasopressin. With erythema and swelling in her arm and chest low dose epinephrine was titrated until her MAP stabilized. At the conclusion of the procedure she had no cuff leak and remained intubated for eight hours. Serum tryptase was elevated at 27.2 ug/L. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM AM MC591 Stat Bilateral Needle Thoracostomies: A Case of Severe Bilateral Tension Pneumothoraces During a Routine Colonoscopy Carmen Rivera, University of Illinois Hospital, Chicago, IL 80-year-old woman ASA VI presented for a colonoscopy. During the procedure oxygen desaturation was noted and massive subcutaneous emphysema was palpated. Her cardiac rhythm rapidly deteriorated to pulseless electrical activity and ACLS protocol was initiated. Immediate presumptive diagnosis of tension pneumothoraces was made. Bilateral needle thoracostomies were performed with immediate return of blood pressure and improved ventilation. Surgical intervention revealed a large cecal tear. After appropriate ICU care patient was discharged home without any long term sequelae. This case highlights the importance of anesthesia providers' ability to quickly recognize and treat this life threatening complication. Monday, October 14 8:00 AM - 9:30 AM AM MC592 The Use of Glidescope for Tracheal Intubation in Patients With Ankylosing Spondylitis Sara Robertson, M.D., Victor Mandoff, M.D., University of Arkansas for the Medical Sciences, Little Rock, AR This patient with ankylosing spondylitis presented for a left CFE. The patient's positioning was a challenge. After being transported to the operating room the patient was positioned on the OR table with several blankets under his back. With fiberoptic intubation equipment immediately available the patient was intubated with the glidescope. This case brings to light a possible equally effective alternative to awake fiberoptic intubation of patients with ankylosing spondylitis-the use of the Glidescope. Monday, October 14 8:00 AM - 9:30 AM OB MC593 Anesthetic Considerations for an EXIT Procedure for a Venolymphatic Malformation Christina Lee, M.D., Manuel Vallejo, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA A 37-year-old G1P0 female with a history of chronic hypertension underwent an EXIT procedure at 36 weeks 6 days GA for a fetal venolymphatic malformation involving the left parotid space with encroachment into the pharynx. General endotracheal anesthesia was induced with a rapid sequence induction. Maintenance was achieved with desflurane and nitrous oxide. After uterine incision the fetal head and right upper extremity were exteriorized. An intravenous catheter was placed in the fetal hand. The fetal airway was secured by pediatric ENT via endotracheal intubation by direct laryngoscopy. The patient was extubated upon completion of surgery and recovered uneventfully. Monday, October 14 8:00 AM - 9:30 AM OB MC594 Peripartum Cardiomyopathy in a Patient With Mild Pre-eclampsia and Twin Gestation Alice Li, Loretta Grecu, M.D., Yale University, New Haven, CT A 32-year-old G1P1002 woman with pre-eclampsia presented with acute shortness of breath and low SaO2 on POD5 after Cesarean-section. Chest X-ray revealed bilateral patchy hazy opacities while TTE Copyright © 2013 American Society of Anesthesiologists showed severe biventricular failure (LVEF 15%). She was diagnosed with peripartum cardiomyopathy. Emergent intubation and intra-aortic balloon pump followed. Despite maximal ventilatory support and management with diuretics and vasodilators she continued to deteriorate with MVO2 35% and SaO2 85%. She underwent emergency BIVAD implantation with ECMO. Three days later ECMO was removed and she was extubated. The BIVAD was removed the following week. Her last LVEF was 55% before being discharged home. Monday, October 14 8:00 AM - 9:30 AM OB MC595 Quadriplegic Parturient With Autonomic Dysreflexia on Therapeutic Anticoagulation for Pulmonary Embolism K. Grace Lim, M.D., Anne Lavoie, M.D., Manoj Kalayil, M.D., Brian Braithwaite, M.D., Christopher Cambic, M.D., Northwestern University Feinberg School of Medicine, Chicago, IL The patient is a 32-year-old G3P1 with C5 quadriplegia after a motor vehicle collision at the age of 19. She has severe autonomic dysreflexia at baseline and had two successful vaginal deliveries in the past under epidural analgesia. During this pregnancy however she was diagnosed with bilateral pulmonary embolisms six weeks prior to labor and delivery requiring therapeutic anticoagulation. We discuss and weigh the evidence risks and benefits of regional anesthesia - an arguably superior mode of control of dysreflexia - in the setting of therapeutic anticoagluation in an immobile parturient. Monday, October 14 8:00 AM - 9:30 AM OB MC596 Venous Sinus Thrombosis After Unintended Dural Puncture and Blood Patch James Lincoln, M.D., Snigdha Ancha, M.D., Mary Im, M.D., Marcus Zebrower, M.D., Drexel University College of Medicine, Philadelphia, PA A 34-year-old female requested elective labor epidural placement. During placement there was return of CSF through 18g Tuohy needle at L3-4 Level. Subsequently an epidural catheter was successfully advanced at the L4-5 level with LOR at 4cm. The epidural facilitated an uncomplicated spontaneous vaginal delivery. Later on PPD#9 patient presented from home for severe positional headache. An epidural blood patch was placed with immediate relief and patient was discharged. On PPD #10 patient was admitted for recurrent headache and found to have right venous sinus thrombosis on MRI. Neurology was consulted and patient improved clinically with therapeutic anticoagulation. Monday, October 14 8:00 AM - 9:30 AM OB MC597 Management of Hypercoagulable Laboring Patient in Rapid Atrial Fibrillation Jon Livelsberger, D.O., Michael Brotspies, D.O., William Somerset, D.O., Temple University Hospital, Philadelphia, PA 27-year-old G8P0250 at 38 weeks with history notable for protein C deficiency, multiple DVTS, and PE presented in early labor. Decision made to provide epidural analgesia, however since anticoagulation would be held during labor, decision made by OB to place IVC filter. After filter placed, via right IJ approach, she returned to L&D in rapid atrial fibrillation (BP 90/50). Cardiac consultation obtained, they advised against cardioversion without anticoagulating. OB was against anticoagulating and soon after declared arrest of labor. A neuraxial technique was attempted; however inadequate sensory blockade mandated induction of general anesthesia in the face of hemodynamic instability. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM OB MC598 Postdural Puncture Headache With Associated Subdural Hematoma Oscar Lopez, NYU, New York, NY 30-year-old Gravida 2 Para 0010 at 35 3/7 weeks gestation presentes for caesarean section for gestational hypertension. Planned for CSE. Positioned sitting midline attempt L3-L4. Tuohy needle advanced to LOR. Positive clear CSF was noted. Second attempt at L2-L3 without complications. Cesarean section performed uneventfully. Remained asymptomatic in hosital. POD 5 developed severe positional frontal headache relieved in supine position. Went to ED CT head showed bilateral 1cm subdural hematomas no midline shift. Patient had no neurologic deficit. Blood patch performed on POD#6. Headache completely resolved on POD #7. Eventually discharged home after 2 days of monitoring. Monday, October 14 8:00 AM - 9:30 AM OB MC599 Delayed Epidural Local Anesthetic Response in a Patient With Severe Preeclampsia Undergoing Cesarean Delivery Sean Malin, M.D., Howard Lee, B.S., Marianne David, M.D., George Washington University, Washington, DC The patient was a 46-year-old G2P0 parturient with sarcoidosis MVP who presents at 26.3 weeks with triplets and severe preeclampsia/HELLP syndrome for urgent Cesarean delivery. The anesthetic plan was for neuraxial blockade by epidural infusion. An epidural catheter was placed and bupivacaine 100mg thirty minutes later lidocaine 100mg fifteen minutes later lidocaine 90mg failed to provide anesthesia adequate for surgery. The decision was made to proceed with general anesthesia. Rapid sequence induction was performed with direct laryngoscopy using a C-mac and a size 6.0 endotracheal tube. Interestingly post-operative pain was well controlled with PCEA through the same catheter. Monday, October 14 8:00 AM - 9:30 AM OB MC600 Subdural Injection or Epidural Anesthesia in a Hypovolemic Patient? A Case Report Looking at Maternal Heart Rate Variation During Contractions. Caroline Martinello, M.D., Felipe Medeiros, M.D., Justin Davis, M.D., Michelle Simon, M.D., Rakesh Vadhera, M.D., F.R.C.A., The University of Texas Medical Branch, Galveston, TX Maternal heart rate (MHR) variability with uterine contractions may be a predictor of volemic status and blood pressure response to neuraxial anesthesia in laboring patients. Limited data is available but there are case reports of hypovolemic patients developing a sinusoidal pattern of MHR on fetal strips with the trough of the MHR curve corresponding to the uterine contractions. We describe a case of shock and respiratory arrest following labor epidural anesthesia with focus on MRH pattern. We additionally discuss possible causes and differential diagnosis such as subdural injection of local anesthetic. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM OB MC601 The Clinical Management of a Suspected Subdural Catheter Placement in a Preeclamptic Parturient Brian McClure, D.O., Ashraf Farag, M.D., Texas Tech University Health Sciences Center, Lubbock, TX This is a case of suspected subdural injection of local anesthetic in an 18-year-old preeclamptic parturient. The patient underwent routine placement of an epidural catheter with a test dose injection of local anesthetic with epinephrine. Approximately four minutes after injection the patient began to feel drowsy light headed and short of breath. Oxygen was administered however the patient desaturated subsequently losing consciousness. She was immediately intubated and ventilated transferred to the operating room where a healthy infant was delivered via forceps. The patient remained stable and was extubated 4 hours later without apparent complications to mother or newborn. Monday, October 14 8:00 AM - 9:30 AM OB MC602 Loss of Airway in a Pregnant Trauma Patient Resulting in Emergent Cesarean Section Shady Adib, M.D., Melanie McMurry, M.D., University of Missouri, Columbia, MO A 34-year-old pregnant female EGA 30 weeks post MVA with multiple facial fractures was scheduled for a tracheostomy and ORIF of facial fractures. She was intubated with a central line and fetal monitoring. After an uneventful surgical course the surgeon inadvertently pulled out the central line and lost the tracheosomy access. The patient became hypoxic and fetal heart tones diminished. The patient was intubated orally. OB performed an emergency cesarean section. The infant required CPR. IV access was eventually regained. The infant was transported to NICU. The patient returned to the ICU with an oral ETT in stable condition. Monday, October 14 8:00 AM - 9:30 AM OB MC603 Complicated Autoimmune Hepatitis and Cesarean Delivery Gustavo Mendes, M.D., Fernanda Mehlmann, M.D., Anibal Vicuna, M.D., Daniel Kim, Monica Siaulys, M.D., Ph.D., ISCMSP, Sao Paulo, Brazil A 22-year-old ASA Physical Status III women presented for cesarean delivery. Past history was significant for autoimmune hepatitis with signs of acute recrudescence (ascites dyspnea and ecchymosis) with few treatment options due to pregnancy. In preoperative evaluation the echocardiogram was unremarkable and blood bank ready for massive blood transfusion. Since patient had clinical signs of coagulopathy general anesthesia technique was chosen and uneventful. During surgery were used 7 platelets units 7 cryoprecipitate units and 3 fresh frozen plasma units and no unexpected bleeding detected. Patient subsequent course was uneventful. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM OB MC604 Postdural Puncture Headache Treatment and Prophylaxis: Treating an Immediate Onset Postdural Puncture Headache With an Epidural Blood Patch Via an Existing Epidural Catheter and then Administering Prophylactic Cosyntropin Jennifer Mendoza, M.D., Heather Nixon, M.D., University of Illinois at Chicago, Chicago, IL We present a parturient (G4P2 at 37wks GA with twin pregnancy) whose first attempt at a labor epidural resulted in an inadvertent dural puncture with the rapid onset of a postdural puncture headache(PDPH). Migration of the placed intrathecal catheter led to inadequate analgesia and a subsequent epidural catheter was placed for labor analgesia. After successful delivery of twins an epidural blood patch was performed utilizing the epidural catheter with immediate relief of PDPH. Then 1 mg of cosyntropin was administered intravenously for PDPH prophylaxis of future headache. The patient was discharged on postpartum day 3 without complication or headache. Monday, October 14 8:00 AM - 9:30 AM OB MC605 Management of Labor Analgesia in a Parturient With a Giant 5 cm Vestibular Schwannoma Keric Menes, M.D., Arti Ori, M.D., Maimonides Medical Center, Brooklyn, NY 25-year-female at 40 weeks presented in active labor. History was significant for resection of a giant cerebropontine angle vestibular schwannoma five years ago. Post resection a residual tumor of 6 x 3 mm tumor was left behind. Recent MRI demonstrated a larger 2.5 x 5.4 x 4.0 cm tumor. Physical exam showed bilateral visual loss persistent imbalance and tinnitus in the left ear. The parturient was placed on PCA morphine pump at a dose of 1 mg every 8 min without an infusion. An arterial line was placed. The parturient delivered vaginally after 10 hours without incident. Monday, October 14 8:00 AM - 9:30 AM OB MC606 Anesthetic Management of a Pregnant Patient With Suspected Placenta Percreta. Daniela Micic, Jae Park, University of Southern California, Los Angeles, CA A 28-year-old G3P2 female pregnant with twins in active labor was urgently brought to the operating room for caesarian section. The patient had suspected placenta percreta. Quickly an anesthetic plan was formulated with the obstetricians and urologists. An arterial line and central line were placed while the patient was awake for monitoring and access. The surgeons scrubbed and sterilely prepped the patient prior to anesthesia induction. Rapid sequence induction and intubation were performed and a caesarian section was safely and successfully carried out. The patient then underwent a hysterectomy without complications. Monday, October 14 8:00 AM - 9:30 AM OB MC607 Neuraxial Analgesia for Labor After Epidural Steroid Injections Merrick Miles, UNC, Durham, NC, Kimberley Nichols, UNC Hospitals, Chapel Hill, NC A 37-year-old laboring multiparous female requested a lumbar epidural for analgesia. Her past medical history was notable for chronic low back pain treated with lumbar epidural steroid injections. The epidural placement was uneventful via a loss of resistance technique but the patient had a positive test Copyright © 2013 American Society of Anesthesiologists dose for intrathecal placement. No significant analgesia was experienced and the decision was made to replace the catheter. The second catheter threaded easily but CSF was aspirated. This catheter was managed successfully as an intrathecal catheter but the patient suffered a post-dural puncture headache that required an epidural blood patch for resolution. Monday, October 14 8:00 AM - 9:30 AM OB MC608 Anesthetic Management of a Parturient With Limb-Girdle Muscular Dystrophy for Caesarean Section Larkin Mitchell, M.D., Eric Hutto, M.D., Arthur Calimaran, M.D., University of Mississippi Medical Center, Jackson, MS A 25-year-old 59 in 32 kg G1P0 at 34 weeks gestation presented for scheduled caesarean section due to malpresentation and worsening oligohydramnios. She had limb-girdle muscular dystrophy with associated scoliosis and severe restrictive lung disease. Her pre-operative pulmonary function tests revealed FVC 30% of predicted FEV1 31% of predicted and severe decrease in DLCO and she used BiPap at night. History of difficult airway.The anesthetic implications of limb-girdle muscular dystrophy presented a challenging scenario for the peri-operative management of this patient. Monday, October 14 8:00 AM - 9:30 AM OB MC609 Postpartum Hemorrhage in a Parturient With Von Willebrand Factor Disease Type 2A Daria Moaveni, M.D., Katherine Hoctor, M.D., J. Ranasinghe, M.D., University of Miami-Jackson Memorial Hospital, Miami, FL A 31-year-old G2P1001 with von Willebrand factor disease type 2a presented for trial of labor after cesarean at 39 weeks gestation. She requested a labor epidural but the ristocetin cofactor activity was not available to determine the safety of performing a neuraxial technique. Remifentanil PCA was used successfully for labor analgesia. Antihemophilic factor/von Willebrand factor complex (vWFC) was given preemptively during labor. A cesarean delivery was performed for arrest of labor and general anesthesia was administered; vWFC was given during surgery. Despite no excessive intraoperative bleeding in the PACU she developed postpartum hemorrhage requiring additional treatment. Monday, October 14 8:00 AM - 9:30 AM OB MC610 A Multidisciplinary Approach to Acute Aortic Dissection in the Third Trimester of Pregnancy Dominique Moffitt, M.D., Hans Sviggum, M.D., Laura Chang, M.D., Brigham and Women's Hospital, Boston, MA We report a complex case of a 27-year-old female with Marfan's who presented at 28 weeks gestation with a descending thoracic aortic dissection. A multidisciplinary team including obstetrics anesthesia cardiology along with vascular and cardiac surgery coordinated her management and care. She underwent cesarean delivery at 30 weeks gestation in a hybrid operating suite under epidural anesthesia. She returned two weeks postpartum with expansion of the dissection which was then repaired. The cardiovascular physiology of pregnancy and how it influences the risk of aortic dissection in patients with Marfan's will be discussed along with the anesthetic considerations. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM OB MC611 Curious Incidence of Recurrent Postpartum Angioedema Cody Motley, M.D., B.J. Haywood, M.D., Brian Seacat, M.D., Abhinava Madamangalam, M.D., OU Health Sciences Center, Oklahoma City, OK We present a multigravida at 34 weeks gestation complicated by severe gestational hypertension who developed impressive bilateral periorbital and perioral pruritic erythematous edema post-operatively. Onset occurred several hours following an uncomplicated cesarean section with a spinal anesthetic. Resolution of symptoms occurred over the next 24 hours. Her angioedema correlated closely with the mast cell-mediated variety. Interestingly the patient experienced similar symptoms with her previous pregnancy. She denied having known allergies. We will discuss the clinical features causes management and potential risks associated with angioedema in the parturient. Monday, October 14 8:00 AM - 9:30 AM OB MC612 Fever Back Pain and Tenderness 6 Days After a Labor Epidural; Now What? Cody Motley, M.D., Tilak Raj, M.D., B.J. Haywood, M.D., OU Health Sciences Center, Oklahoma City, OK We present a 33-year-old female who presented six days postpartum following an uncomplicated vaginal delivery and epidural analgesia with complaints of fever chills and lower back pain. Exam revealed fever tachycardia and profound tenderness and heat throughout her lower back. Concern for an epidural abscess prompted immediate lumbar spine MRI. Imaging revealed inflammation and cellulitis in the subcutaneous tissues following the epidural needle tract within the L2-3 interspace sparing the epidural space. We will discuss the diagnostic workup treatment and potential risks associated with subcutaneous cellulitis threatening the epidural space and its differentiation from an abscess with images. Monday, October 14 8:00 AM - 9:30 AM OB MC613 Management of Refractory Headache in the Postpartum Patient With Suspected Dural Puncture Jason Mulawa, M.D., William Mansfield, M.D., Roy Soto, M.D., William Beaumont Hospital, Royal Oak, MI AM a 34-year-old G1P0 received a combined spinal-epidural for management of labor pain. PMH was significant for migraines epilepsy scoliosis and spondylolysis. Her epidural provided moderate pain control for 3 hours but required replacement at that time. Repeat epidural provided appropriate pain relief but unexpected motor block suggestive of intrathecal spread of anesthetic. 24hrs after an uneventful NSVD patient presented with positional bifrontal headache. Blood patch was performed with relief of symptoms but patient returned with same symptoms 18hrs after initial presentation. Repeat blood patch similarly relieved symptoms for 18hrs and neurology was consulted for evaluation of persistent symptoms. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM OB MC614 Anesthetic Challenges in Management of an Achondroplastic Dwarf With Preeclampsia Undergoing Cesarean Delivery Shweta Narang, M.D., Neelam Malhotra, M.D., Ramsis Ghaly, M.D., Craig Malk, M.D., John H Stroger Jr. Hospital of Cook County, Chicago, IL 29-year-old G3P1102 parturient at 28.4 weeks gestation with known achondroplastic dwarfism history of 2 previous Cesarean deliveries presents with elevated blood pressures proteinuria diagnosed with severe preeclampsia. She had a class 4 Mallampati classification and limited neck extension. Laboratory data was remarkable for platelet count of 92 000/microliter (downtrending) with normal liver functions and coagulation. For Cesarean delivery and tubal ligation continuous lumbar epidural was placed early. In the OR 2% lidocaine with epinephrine was titrated in 3 ml increments and T4 sensory level was achieved with 15 ml. Surgery proceeded uneventfully with delivery of a baby with APGARS 4/7. Monday, October 14 8:00 AM - 9:30 AM OB MC615 Anesthetic Management of a Jehovah's Witness Parturient With Complete Placenta Previa and Unicornuate Uterus for Cesarean Section. Michael Nayshtut, D.O., Zana Borovcanin, M.D., University of Rochester, Rochester, NY We present a 35-year-old G5P3 term Jehovah's Witness scheduled for an elective cesarean section for a complete placenta previa. Despite multiple risk factors for intraoperative hemorrhage the patient refused transfusion of all blood products other than cryoprecipitate autologous blood via cell saver Factor VII Factor VIII and volume expanders for religious reasons. Prior to the operative day thorough discussion with the patient took place along with extensive planning and coordination among the obstetric and anesthesiology teams in order to achieve the best possible outcome. Fortunately the caesarean section was uneventful resulting in a viable delivery with APGARS 8 9. Monday, October 14 8:00 AM - 9:30 AM OB MC616 Anesthetic Considerations in Parturients With CNS Shunts for Hydrocephalus: A Case Series Karl Nazareth, M.D., Nenna Nwazota, M.D., Baylor College of Medicine, Houston, TX The prevalence of women with CNS shunts surviving to reproductive age is increasing as diagnosis and treatment of intracranial abnormalities improves. Thus the anesthetic considerations for labor management in these patients are an increasing challenge. This case series involves three parturients with hydrocephalus of varying etiologies who underwent either neuraxial or general anesthesia for delivery. Several important issues regarding use of neuraxial anesthesia in the setting of intracranial hypertension and special considerations for cesarean deliveries under general anesthesia are discussed in-depth. This case series is the first to date in this unique patient population. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 8:00 AM - 9:30 AM OB MC617 Obstetric Epidural Catheter Placement in a Patient With a Myelomeningocele David Nguyen, M.D., Timothy Bednar, M.D., Husong Li, M.D., Ph.D.,The University of Texas Medical Branch, Galveston, TX The parturient patient with spina bifida meningocele or a myelomeningocele can often be a challenging patient to manage from an anesthetic perspective. Reviewing the anatomy and pathophysiology in these patients can help in the obstetric patient. A detailed neuraxial anesthetic plan with backup plans including general anesthesia is recommended after discussion with the patient and obstetrician. We describe a case of a patient with a myelomeningocele requiring a Cesarean-section after a failed trial of labor. We describe our approach to neuraxial anesthesia in this parturient population and expand the discussion to gravid patients with spina bifida or a meningocele. Monday, October 14 8:00 AM - 9:30 AM OB MC618 Maternal Cardiac Arrest From Amniotic Fluid Embolism in the Setting of Severe Pre-Eclampsia Intrauterine Fetal Demise (IUFD) and Disseminated Intravascular Coagulation (DIC) Travis Nickels, M.D., Olusegun Senbore, M.D., Cleveland Clinic Foundation, Cleveland, OH 36-year-old G5P4 at 29 weeks gestation with known pre-eclampsia was transferred to our facility after diagnosis of placental abruption and IUFD. Upon admission to our Labor and Delivery unit the patient was hypertensive and complaining of painful contractions. She was also noted to be anemic and in severe DIC. Our team worked with Obstetrics to stabilize the patient and correct the coagulopathy. Following Cytotec induction and artificial rupture of membranes the patient became dyspneic and cyanotic. 20 minutes later she acutely deteriorated and went into cardiopulmonary arrest. She was intubated and taken immediately to the OR for emergency cesarean. Monday, October 14 8:00 AM - 9:30 AM OB MC619 Difficult Emergent Endotracheal Intubation in the Setting of Postpartum Flash Pulmonary Edema Karmin Nissan, Heather Nixon, M.D.,University of Illinois Chicago Medical Center, Chicago, IL A 32-year-old parturient (BMI 52) developed severe pre-eclampsia in the postpartum period with flash pulmonary edema necessitating emergent endotracheal intubation. The obstetric anesthesiology team who were previously aware of the patient responded to the decompensation in the intensive care unit with advanced equipment which ultimately allowed for difficult but successful endotracheal intubation. This clinical scenario demonstrates the risks of severe pre-eclampsia in the immediate postpartum period the utility of obtaining an obstetric anesthesiologist to assist in the management of postpartum patients and the yield of using advanced airway equipment as first-line management in an emergency off-site postpartum airway.

Monday, October 14 8:00 AM - 9:30 AM OB MC621 Anesthetic Management of Labor and Delivery in a Parturient With Pseudotumor Cerebri Junaid Nizamuddin, M.D., Massachusetts General Hospital, Boston, MA, Laura Chang, M.D., Brigham and Women's Hospital, Boston, MA An 18-year-old female with a history of pseudotumor cerebri status post recent removal of infected ventriculoperitoneal shunt presented with preterm labor at 31 weeks gestation. She reported recurrent headaches accompanied by blurry vision during pregnancy suggesting worsening of her intracranial hypertension. An intrathecal catheter was placed to allow for drainage of cerebrospinal fluid and for analgesia during labor and delivery. She was able to Valsalva with uterine contractions and with a spontaneous vaginal delivery without worsening of her neurologic symptoms and delivered a healthy female. Monday, October 14 8:00 AM - 9:30 AM OB MC622 Anesthetic Implications of Narcolepsy/Cataplexy Regarding Neuraxial Anesthesia for Cesarean Section Casey Windrix, M.D., Alexander Nowlin, Student, Abhinava Madamangalam, M.D., University of Oklahoma, Oklahoma City, OK An urgent Cesarean delivery was required for a 35 week gestation in breech presentation and severe preeclampsia. Narcolepsy/Cataplexy was the only significant medical history characterized by daily episodes of sleepiness and loss of muscle tone precipitated by intense emotions or extreme stress. The patient desired to be awake for the birth of the child; though she was concerned that during regional anesthesia she would experience a cataplectic event a sentiment shared by the obstetricians. After careful planning and focused patient counseling we administered neuraxial anesthesia for an uneventful Cesarean section. We detail the anesthetic planning. Monday, October 14 8:00 AM - 9:30 AM OB MC623 Management of Parturient With Malaria Requiring Caesaran Section Christiana Obi, D.O., Steven Halle, M.D., SLR Hospital Center NY, New York, NY This case discusses the anesthetic management of a 36-year-old G5P4 at 36 weeks gestation with newly diagnosed malarial infection undergoing an emergent c-section. The patient recently returned from a Copyright © 2013 American Society of Anesthesiologists two week stay in the Ivory Coast where she manifested constitutional symptoms two weeks after returning to the U.S. Consultation by OB/Gyn as well as Infectious Disease and Hematology-Oncology was done with presumptive diagnosis of malaria. Peripheral smear consistent with Plasmodium. Emergent c-section decided secondary to signs of fetal distress with subsequent administration of general anesthesia. Anesthetic considerations for the gravid patient with malaria discussed. Monday, October 14 8:00 AM - 9:30 AM OB MC624 Challenging Case Report:Peripartum Anaphylaxis Versus Amniotic Fluid Embolism Mauricio Jacques, M.D., Jason O'Neal , Stephen Pratt, M.D., Beth Israel Deaconess Medical Center Harvard Medical School, Boston, MA A 38-year-old woman G4P2 with no significant medical history presented at 39.2 weeks of gestation. A combined spinal/epidural was administered. The patient developed hypotension with associated fetal bradycardia after the placement. An emergent cesarean section was performed. The patient developed a generalized rash and hypotension with persistent tachycardia without respiratory symptoms. She was treated for anaphylactic shock. Postoperatively the patient continued to bleed in recovery. Coagulation tests were consistent with DIC. The patient returned to the OR for surgical re-exploration. Massive transfusion protocol was initiated. A TTE showed evidence of severe right ventricular failure suspicious for pulmonary embolism. Monday, October 14 8:00 AM - 9:30 AM OB MC625 Anesthesia Practice in Rural Zambia: Massive Blood Loss Due to Uterine Rupture Alicja Orkiszewski, M.D., Private Practice, Palo Alto, CA, Aleksandra Orkiszewska, , M.D., Private Practice, Chicago, IL, Laura Marijke Heman, M.D., Lumezi Mission Hospital, Lundazi, Zambia 27-year-old pregnant multiparous female was brought to OR in unstable condition for emergency laparotomy (uterine rupture). Local hospital did not have anesthesia machine electrocoagulation or oxygen. Surgery was performed under i.v. Katamine and Propofol. Vital signs were monitored visually and with NIBP stethoscope and pulsoxymeter. Hemostasis was achieved with uterus repair and laps that were removed later. EBL was 3 liters. During surgery patients received 5 l of fluids and 1 unit of blood. 2nd unit was transfused later postoperatively. After surgery pain was controlled with Acetaminophen Ibuprofen and Vicodin. Patient was dischared home POD # 9 with Hb-6. Monday, October 14 8:00 AM - 9:30 AM OB MC626 The Difficulties Of Epidural Analgesia in a Patient With Right Sided Heart Lesions : A Bleeding Diathesis Post Spinal Fusion Jeffrey Pack, M.D., University of New Mexico, Albuquerque, NM A 28-year-old female G-1 P-0 with history of Bernard-Soulier disease severe scoliosis with T-1-L2 fusion and tetralogy of Fallot S/P multiple repairs now with severe pulmonary outflow stenosis and valvular regurgitation presented to Obstetric Triage with spontaneous rupture of membranes. For labor analgesia a multi-modal approach was discussed including risks and benefits; the patient desired epidural analgesia. A platelet transfusion was given to address her platelet dysfunction. Ultrasound was considered for use in placement of the epidural but after exam an L-3-4 epidural was placed easily in Copyright © 2013 American Society of Anesthesiologists traditional manor. The epidural was bolused incrementally; safety and excellent analgesia were achieved. Monday, October 14 8:00 AM - 9:30 AM OB MC627 Intrathecal Catheter Use in Morbidly Obese Pregnancy Anuj Patel, M.D., Jeron Zerillo, M.D., Andrew Perez, M.D., Mount Sinai School of Medicine, New York, NY A 34-year-old morbidly obese (BMI 72) and severely pre-eclamptic G4P3 at 29 weeks GA admitted with ARF on CKD presented for caesarean section from ICU. Neuraxial epidural anesthesia was selected for management of her delivery. After achieving adequate loss of resistance without CSF return threading of the catheter resulted in CSF leakage. At this point we chose to place the catheter intrathecally for the procedure anticipating difficulty in placing an epidural catheter at a different lumbar level. The caesarean section proceeded without incident. Subsequently the patient was discharged but readmitted with respiratory distress several months later ultimately expiring. Monday, October 14 8:00 AM - 9:30 AM OB MC628 Anesthetic Management of a Parturient With Congenital Prolonged QT Syndrome Requiring a Life Vest Kelly Peretich, M.D., Andrew Gentilin, M.D., Manuel Vallejo, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA A 28-year-old G3P2 woman with congenital prolonged QT syndrome presented for planned repeat Cesarean section. In her second trimester she began having symptomatic palpitations requiring a Zoll defibrillator Life Vest and was started on atenolol. Baseline QTc was 489 ms and preoperative serum electrolytes were within normal limits. In the OR the vest was removed Zoll pads were placed on her chest and set to monitor and pace mode.

This occurs from a defect in the decidua basalis resulting in chorionic villi invasion into myometrium. This condition is often managed by cesarean hysterectomy; however recent advances allow for uterine preservation via uterine artery embolization. We present a patient with complete placenta previa and accreta who underwent repeat cesarean and bilateral uterine artery embolization under combined spinal-epidural anesthesia. An epidural was placed at T9-T10 for post-op pain control and spinal was done at L4-L5. The procedure was completed without significant bleeding and post-op pain was well controlled.

Presenting symptoms included postural occipital headache and neck stiffness. She Copyright © 2013 American Society of Anesthesiologists underwent three epidural blood patches and developed decreased vision the evening after the third blood patch. Ophthalmology Neurology and Neurosurgery were consulted. Initial MRI was concerning for subdural hemorrhage however a repeat MRI showed white matter changes associated with PRES. The patient was diagnosed with PRES in the setting of post-partum hypertension. Presenting symptoms of PRES and PDPH may be similar making the initial diagnosis of PRES challenging. Monday, October 14 8:00 AM - 9:30 AM OB MC634 Cesarean Section Convulsion Coagulopathy and Cardiovascular Collapse Shervin Razavian, M.D., Frank Sahli, M.D., Venesa Ingold, M.D., The University of Kansas Medical CenterKansas City, Kansas City, KS We present the case of a cesarean section delivery that was complicated by an intraoperative seizure with simultaneous cardiovascular collapse and patient hemorrhage which we believe to be likely secondary to an amniotic fluid embolism (AFE). AFE remains a rare complication of obstetrical procedures with a recently estimated incidence of 2 per 100 000 deliveries. If not recognized quickly and treated promptly and properly the condition is fatal. In total our patient was resuscitated with 8 units of packed red blood cells 7 units of platelets 6 units FFP and 10 units of cryoprecipitate. She was discharged home on POD 4. Monday, October 14 8:00 AM - 9:30 AM OB MC635 A Combustion in the Anesthesia Machine in the Labor and Delivery Suite Leah Reimer, NYU Medical Center, New York, NY A 31-year-old G1P0 woman was admitted for induction of labor. Co-morbidities included scoliosis s/p Harrington rod placement through L4. An epidural in the L5-S1 interspace resulted in incomplete relief during labor. An uncomplicated c-section under GETA ensued due to non-reassuring fetal status. As the patient was extubated a loud bang and burning smell emanated from the anesthesia machine. The patient was immediately transferred unharmed. Investigation revealed that a foreign material introduced into the Spirolog expiratory flow sensor in the Draeger Apollo anesthesia machine lead to ignition and combustion. An ongoing investigation commenced including recommendations from the ECRI institute. Monday, October 14 8:00 AM - 9:30 AM OB MC636 Anesthetic Management for Cesarean Delivery in the Setting of Acute Hepatic Failure and Pulmonary Hypertension Goran Ristev, Bryan Mahoney, M.D., Ohio State University Wexner Medical Center, Columbus, OH A 38-year-old female G4P3 at 28w5d presents with jaundice epistaxis edema and transaminitis. Evaluation revealed acute hepatic failure in the setting of hepatitis C cirrhosis further complicated by coagulopathy and pulmonary hypertension. At 28w5d cesarean delivery was performed due to absent umbilical artery end-diastolic flow and worsening maternal condition. A male infant was successfully delivered under general anesthesia utilizing invasive arterial and central venous pressure monitoring for potential hemodynamic instability. Intraoperative bleeding and coagulopathy were managed with 5U FFP 4U PRBC 2U cryoprecipitate and 1U platelets followed by successful extubation in the operating room.

Monday, October 14 8:00 AM - 9:30 AM OB MC645 Patient With Anterior Horn Cell Disease for Cesarean Section: Neuraxial or General Anesthesia? Usha Saldanha, M.D., Sergey Pisklakov, M.D., UMDNJ-NJMS, Newark, NJ Anterior Horn Cell Disease (AHCD) is caused by degeneration of motor neurons. Some anesthesiologists consider neuraxial anesthesia contraindicated in this group due to possible further neurologic decline. We report a case of a patient with a long history of AHCD where spinal anesthesia was successfully used for cesarean section. Her recent electromyography showed involvement of lower cervical and upper thoracic roots and her neurologic status was stable for the last two decades. After weighing all risks and benefits we decided to proceed with spinal anesthesia. Cesarean section was uneventful. Patient regained full function postoperatively with no exacerbation of her condition. Monday, October 14 8:00 AM - 9:30 AM OB MC646 Anesthetic Management of Hyperthyroid Storm With Congestive Heart Failure and Pulmonary Edema in Pregnancy Mical Samuelson Duvall, M.D., Shilpadevi Patil, M.D., LSUHSC Shreveport, Shreveport, LA We present a patient with diagnosis of uncontrolled hyperthyroidism congestive heart failure (CHF) and pulmonary edema in the setting of third trimester pregnancy. Hyperthyroidism is a difficult disease in terms of diagnosis and maintaining patient compliance with medication. Non-compliance leads to significant cardio-pulmonary morbidity. As a consequence successfully treating uncontrolled hyperthyroidism presents a unique challenge in pregnant patients. In these patients it is clinically important to place hemodynamic monitoring. C-section may also be necessary to treat patients who are refractory to medical management.

Monday, October 14 10:30 AM - 12:00 PM CA MC665 Emergent Sternotomy and Cardiopulmonary Bypass for Removal of a Foreign Body During Pacemaker Replacement Charles Jones, M.D., Samuel Dejo, M.D., Metro Health Medical Center, Cleveland, OH We are presenting a 20-year-old female with a history of congenital heart block scheduled for a pacemaker removal and reimplantation. After routine induction and endotracheal intubation anesthesia was maintained with isoflurane fentanyl propofol and rocuronium for muscle relaxation. Intraoperatively cardiology was unable to remove the right ventricular epicardial lead or retrieve their guidewire. At this point an emergent sternotomy was performed and the patient was placed on cardiopulmonary bypass to remove the foreign bodies. Post-operatively she was taken to the surgical intensive care unit trachea extubated on post-op day 1 and discharged home on post-op day 3. Monday, October 14 10:30 AM - 12:00 PM CA MC666 Anesthetic Management of a Parturient With Newly Diagnosed Hereditary Hemorrhagic Telangiectasia Zachary Jones, M.D., UT Houston, Houston, TX The patient is a 25-year-old F G2P1 at 36wks gestation presenting with worsening dyspnea and lower extremity edema. CXR showed pulmonary edema. An echo showed a 4.2cm dilated aortic root. She had Copyright © 2013 American Society of Anesthesiologists a history of a pulmonary AVM and a saccular right internal carotid aneurysm increasing in size. CT showed hepatic AVMs. She was newly diagnosed with Hereditary Hemorrhagic Telangiectasia (HHT). Due to risk of worsening acute heart failure rupture of carotid aneurysm and dissection of aortic root pt. received successful epidural and had an urgent c-section. Echo unchanged post-partum. Monday, October 14 10:30 AM - 12:00 PM CA MC667 Postoperative Takotsubo Cardiomyopathy After Pneumoperitoneum Induced Asystole Pranjali Kainkaryam, M.D., Lori Circeo, M.D., Baystate Medical Center, Springfield, MA A 48-year-old woman with severe gastro-esophageal reflux disease presented for a laparoscopic Nissen fundoplication. Rapid sequence induction and intubation were uneventful. Asystole occurred immediately after insufflation of carbon dioxide in the peritoneal cavity. ACLS was initiated and normal sinus rhythm was restored after 3.5 minutes. Laparoscopy ruled out an intra-abdominal injury. Transesophageal echocardiography showed no intra-cardiac air but demonstrated global hypokinesis and apical ballooning of left ventricle. No coronary artery disease was found on cardiac catheterization which confirmed the diagnosis of Takotsubo Cardiomyopathy. She required post-operative ICU care and was discharged home in good condition on post-operative day 6. Monday, October 14 10:30 AM - 12:00 PM CA MC668 Aortic Valve Replacement Via Minithoractomy: Cerebral Desaturation During Aortic Cross Clamp Aruna Kamath, Albert Perrino, M.D., Wanda Popescu, M.D., Yale-New Haven Hospital; Veterans Affairs Medical Center - West Haven, New Haven, CT A 52-year-old male with a quadricuspid aortic valve and severe aortic regurgitation presented for aortic valve replacement via right minithoracotomy. Cerebral oximetry values were within normal limits until the aortic cross clamp was applied. Significant cerebral desaturation was noted values < 65% concomitant with a large backflow of blood in the side port of the cordis catheter. Upon surgical inspection the aortic cross clamp was found to have obstructed two thirds of the superior vena cava. The anesthetic challenge was to recognize complications associated with minithoractomy and to discern signs symptoms and physiology of superior vena cava obstruction. Monday, October 14 10:30 AM - 12:00 PM FA MC669 How Should a Patient With ICD be Managed for Upper Extremity Surgery? Cosmin Guta, Razvan Hurezeanu, M.S., Cleveland Clinic Foundation, Weston, FL 65-year-old male with an ICD/pacemaker and history of hepertension diabetes presented for surgery on the left elbow. Anesthesia team planned to use a magnet for the deactivation of the ICD. Despite the magnet use four discharges from the ICD were noticed during the case. Several attempts to reposition the magnetic device proved unsuccessful probably due to the position of the left arm in right lateral decubitus. The ineffectiveness of the deactivation method has prompted us to reevaluate our practice to use a magnet to deactivate an ICD instead of a reprogramming approach. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC670 Intracranial Hemorrhage Following a Liver Mass Resection Cosmin Guta, M.D., Wagih Gobrial, M.D., Cleveland Clinic Foundation, Weston, FL, Razvan Hurezeanu, M.S., Ross University School of Medicine, Dominica A 61-year-old male with a history of new onset hypertension for the previous 2 months was scheduled for hepatic/adrenal tumor removal. Initial Preop work up for the hypertension indicated pheocromacytoma but repeat testing found this to be negative. Intraoperatively the patient went into hypertensive crisis with a systolic pressure in the 300s subsequently developing a left basal ganglia ICH. Postop the patient recovered from the ICH while the BP normalized with no paroxysmal events. The events noted intraoperatively are classically associated with peochromacytoma but multiple pathology exams were unable to confirm it. Monday, October 14 10:30 AM - 12:00 PM FA MC671 Anesthetic Challenges Associated With a New Treatment for Severe Asthma Cosmin Guta, M.D., Carlos Cajina, M.D., Wagih Gobrial, M.D., Cleveland Clinic Foundation, Weston, FL, Anthony Han, M.D., Ph.D.,Texas Tech University, El Paso, TX Anesthetic Challenges Associated with a New Treatment for Severe Asthma Bronchial Thermoplasty (BT) is an alternative for refractory severe asthma. BT utilizes controlled radiofrequency to ablate smooth muscles lining the airways thereby limiting constrictive potential of airway muscles. Four patients underwent three sessions of BT each in our department. A balanced general anesthesia (GA) technique was used. Oxygen flows were maintained at 8L during the procedure due to significant leakage around the bronchoscope. Patients tolerated the procedure without any significant complication. GA facilitated stable intraoperative hemodynamics and provided a secure airway while maintaining complete suppression of the cough reflex. Monday, October 14 10:30 AM - 12:00 PM FA MC672 Extreme Acidosis After Multisystem Trauma: How Low Can-You Go? Jonathan Hadaway, M.D., Nicole Dobija, M.D., Matthew Waldron, M.D., University of Florida College of Medicine, Gainesville, FL We present a case of intraoperative resuscitation of a 44-year-old male undergoing emergent exploration for intraabominal hemorrhage after high-impact multisystem trauma. The patient arrived to OR in extremis; perioperative course was complicated by ongoing hemorrhage coagulopathy and severe acidosis (baseline ABG 6.68/72.6/125/8). Treatment included massive transfusion correction of respiratory component electrolyte and coagulation abnormalites and ~400 mEq sodium bicarbonate. The patient was transferred to ICU stable. Hospital course included 4 more operations and 2 weeks intensive care. After 3 weeks the patient was extubated neurologically intact and planned for discharge to inpatient rehabilitation. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC673 Protectors of the Airway Mohammed Hamdani, M.D., Ammar Alamarie, M.D., Sarah Stuart, M.D., SUNY Upstate Medical Center, Syracuse, NY The case is about a 35-year-old morbidly obese male admitted to MICU with acute pancreatitis secondary to hypertriglyceridemia complicated by respiratory failure and acute kidney injury. The patient was scheduled for a tracheostomy due to prolonged intubation. In route to the OR the patient had desaturations down to the 60's requiring recruitment maneuvers and manual ventilation to maintain saturations. At the onset of the procedure the surgeon elected to perform a bronchoscopy during which the tip of the bronchoscope was sheared in the ETT causing airway obstruction. This required emergent reintubation. Monday, October 14 10:30 AM - 12:00 PM FA MC674 Anesthesia and Acute Myelopathy: Offender or Bystander Elizabeth Hankinson, M.D., Ahmed Zaky, M.D ., University of Washington VAPSHCS, Seattle, WA A 71-year-old gentleman with esophageal carcinoma underwent esophagectomy under general and epidural anesthesia following neoadjuvant therapy. Post-operatively the patient recieved fluids for hypotension and developed atrial fibrillation. Post-operative day two the patient had sensory and motor deficits below L1. Spine MRI showed non-compressive increased T2 signal T9 to the conus with central cord enlargement suggestive of transverse myelitis. Steroids were started with mild improvement in sensory function. Subsequently the patient developed multi-organ failure secondary to surgical complications and care was withdrawn. Monday, October 14 10:30 AM - 12:00 PM FA MC675 Airway Management in a Patient With Hereditary Angioedema and Allergies to Danazol and C1Esterase Inhibitor Concentrates Virginia Hardie, M.D., Allyson Hascall, M.D University of Nebraska Medical Center, Omaha, NE Hereditary angioedema is a potentially life-threatening condition characterized by spontaneous swelling of the gastrointestinal tract and airway. It is triggered by minor tissue trauma and does not respond to antihistamines steroids or epinephrine. A 66-year-old female with a history of hereditary angioedema presented for esophagogastroduodenoscopy. The patient had a history of allergic reaction to danazol and C1-esterase inhibitor concentrates which are standard prophylactic treatments. Our management plan included a secured airway prior to pharyngeal manipulation and a prophylactic dose of the treatment medication ecallantide which is normally reserved for acute attacks only. The patient's perioperative course was uneventful. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC676 Saved by the Tube: A Case of Threatened Airway Obstruction Following Arthroscopic Shoulder Repair Nazish Hashmi, M.D., Sabina Khan, M.D., University of Arkansas for Medical Sciences Little Rock, AR, Teodora Terlea, M.D., John L. McClellan Memorial Veterans Hospital, Little Rock, AR A 51-year-old healthy male presented for a right arthroscopic rotator cuff repair. He had a previous shoulder arthroscopy with no complications. General anesthesia was induced with propofol fentanyl and succinylcholine. He was intubated and positioned in left lateral decubitus. The operation lasted three hours. Upon removal of drapes significant facial and upper chest swelling was noted. He was left intubated and transferred to the PACU on sedation. The head of the bed was elevated to 30 degrees. One hour postoperatively his facial swelling decreased significantly and he was extubated and subsequently discharged home. Monday, October 14 10:30 AM - 12:00 PM FA MC677 The Epiglottis is Where? The Case of a Displaced Epiglottis Obscuring the Glottic Opening Following Glidescope Intubation and Other Complications of Glidescope Use Elizabeth Healy, M.D., Tripti Kataria, M.D., Jonathan Lusardi, M.D., University of Chicago, Chicago, IL A 58 F with history of left tonsil and base of tongue cancer presents for panendoscopy and esophageal dilation after completion of CRT. Rapid sequence induction with atraumatic Glidescope® intubation was performed. Direct laryngoscopy by surgeon revealed subluxation of the epiglottis into the tracheal inlet with complete blockage of the glottic opening. Suction was passed along edge of ETT and with concurrent laryngeal manipulation the epiglottis was flipped back into position with no apparent injury. Patient extubated transferred to PACU and discharged the same day. Potential post-operative complications could include sore throat hoarseness vocal cord injury and upper airway obstruction. Monday, October 14 10:30 AM - 12:00 PM FA MC678 Anesthetic Management of a Patient With Acute Polysubstance Intoxication Presenting With Traumatic Open Globe Injury Joshua Heller, M.D., Richard Abel, M.D., Nicole Ansell, M.D., Stanley Kang, M.D., Icahn School of Medicine at Mount Sinai, New York, NY A 34-year-old morbidly obese man with no known past medical history presented with a traumatic open globe rupture. Upon interview with the patient the anesthesiology team learned that he had been actively abusing cocaine methamphetamine and ethanol and had not slept for several days. Physical exam revealed a potentially difficult airway. Monday, October 14 10:30 AM - 12:00 PM FA MC679 Unexpected Myocardial Infarction Status Post Low Risk Procedure Mada Helou, M.D., Paul Kempen, M.D., Cleveland Clinic Foundation, Cleveland, OH 39-year-old male presented with otherwise minimal past medical history (including hyperlipidemia and active tobacco abuse) for urethral stricture. A reportedly uneventful anterior stage I urethroplasty occurred under Sevoflurane rocuronium fentanyl and hydromorphone anesthetic with the exception of Copyright © 2013 American Society of Anesthesiologists a short period of tachycardia during emergence lasting one minute. After two hours in the PACU retrosternal chest pain with hypotension 66 mmHg systolic ensued leading to immediate EKG transcription revealing hyperacute anterior ST elevation and TTE echo documenting anterior wall motion abnormality. Emergent mobilization into the catheterization lab occurred concomitant to stabilizing and lifesaving interventions. Monday, October 14 10:30 AM - 12:00 PM FA MC680 Intraoperative Anaphylaxis After Temporally Related Administered of Intravenous Albumin Emily Herschmiller, M.D., Robert Weller, M.D., Wake Forest University, Winston-Salem, NC A 60-year-old male with obesity diabetes and ulcerative colitis s/p proctocolectomy underwent emergent surgery for strangulated parastomal hernia. He received cephazolin and rocuronium prior to incision. After uneventful two hours he developed hypotension treated with albumin 5%. Hypotension worsened and wheezing tachycardia and erythema developed. Anaphylaxis was suspected and BP and ventilation improved after epinephrine dexamethasone and diphenhydramine. The patient showed extensive urticaria and required postoperative ventilation and epinephrine infusion. He was extubated on POD 1 and recovered to discharge. Tryptase was elevated at 24 µg/L Albumin was suspected as the allergen. Allergy consultation and testing is scheduled. Monday, October 14 10:30 AM - 12:00 PM FA MC681 Prehospital Laryngotracheal Injury: Complication of Esophageal Sealing Cuffed Supraglottic Airway Devices (SADs) Kenneth Hiller, M.D., University of Texas at Houston, Houston, TX This case details prehospital respiratory arrest and complications from King LTS™ insertion following unsuccessful endotracheal intubation (ETI) and SAD placement attempts. On hospital arrival chest tubes relieved pneumothoraces however subcutaneous emphysema (Panel A) continued to increase. Laryngotracheal injury was suspected. Fiberoptic exam revealed arytenoid edema (Panel B). Open surgical dissection revealed air bubbles distal to the glottis. The tracheostomy balloon was inflated distal to the laryngotracheal tear. Subsequent chest x-ray (Panel C) demonstrated significant resolution of subcutaneous emphysema. Maintaining SAD placement and avoiding ETI ensured visual confirmation of the presence and location of the tear and prevented exacerbation of injury. Monday, October 14 10:30 AM - 12:00 PM FA MC682 Irregular Heart Rate In An Otherwise Healthy Woman Lee Hingula, M.D., Tori Myslajek, M.D., Yale New Haven Hospital, New Haven, CT A 64-year-old woman presented for laparoscopic cholecystectomy. The patient was noted to have an irregular heart rhythm on the pulse oximeter with a rate of 77 beats per minute. When asked about her medical history she recalled having an irregular heart rhythm since childhood but did not know the diagnosis. She never experienced palpitations chest pain or symptoms consistent with heart failure. An EKG demonstrated ventricular trigeminy. The patient was brought to surgery induced uneventfully and her rhythm reverted to normal sinus. She remained in normal sinus rhythm until her discharge from the post-anesthesia care unit. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC683 Severe Persistent Succinylcholine-Induced Hyperkalemia in an Ambulatory Patient Juliann Hobbs, M.D., M.P.H., Charles Brudney, M.B.Ch.B., Duke University Medical Center, Durham, NC An obese 66-year-old male with no known renal disease and normal serum chemistry values presented for outpatient shoulder surgery. Approximately one hour after induction of anesthesia and administration of succinylcholine the ECG demonstrated signs of hyperkalemia and his serum potassium was found to be 7.4 mmol/liter. He was treated with calcium insulin and furosemide and recovered uneventfully. Calculation of his glomerular filtration rate (GFR) revealed significant renal dysfunction despite serum creatinine within normal limits. Anesthesiologists should consider the risk of hyperkalemia when using succinylcholine and evaluate patients' renal function based on GFR rather than solely on serum creatinine values. Monday, October 14 10:30 AM - 12:00 PM FA MC684 Anesthetic Management of Difficult Double-Lumen Endobronchial Tube and Bronchial Blocker Placement Nicole Hollis, D.O., Jeffery Gross, M.D., University of Connecticut, Farmington, CT 48-year-old woman with recurrent lung cancer to her right middle lobe presented for a right thoracotomy. Significant medical history included lung cancer (s/p right upper lobectomy). Resection required one-lung ventilation. Airway management included initial failed placement of a 35French left double-lumen endobronchial tube (DLT); despite fiberoptic assistance the bronchial lumen persistently entered the right mainstem. A 35French right DLT was easily inserted but did not provide adequate lung isolation. Finally lung isolation was accomplished with a bronchial blocker through a single lumen endotracheal tube. We suspect that difficulty placing the DLT was due to altered anatomy from the prior thoracotomy. Monday, October 14 10:30 AM - 12:00 PM FA MC685 Anesthetic Management for Removal of a Sewing Pin From the Trachea Christopher Howson, M.D., Stephen McHugh, M.D., Li-Ming Zhang, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA Providing anesthesia for patients with inhaled foreign bodies presents a unique challenge for anesthesiologists. Standard methods of airway management frequently cannot be used. Communication with the proceduralist and an understanding of the procedure and physiologic consequences of common anesthetic medications are of vital importance. This case involves a 31-year-old woman who presented for suspension laryngoscopy after accidentally inhaling a sewing pin into her trachea. Anesthetic considerations included maintenance of spontaneous ventilation obtaining an adequate depth of anesthesia to tolerate prolonged suspension laryngoscopy without the use of muscle relaxants and the avoidance of endotracheal intubation. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC686 Retrograde-Assisted Fiberoptic Intubation in a Patient With Unanticipated Difficult Airway Jia Huang, M.D., Edwin Weeks, M.D., George Vaida, M.D., NYU Medical Center, New York, NY A 67-year-old female with an otherwise normal airway exam was scheduled for laparoscopic bilateral salphingo-oophorectomy. General anesthesia was induced with propofol and fentanyl; and the patient was paralyzed with rocuronium. She was easily ventilated but found to be difficult to intubate. Attempts to intubate her with direct laryngoscopy using different blades the glidescope fiberoptic intubation +/glidescope guidance and the intubating LMA +/- fiberoptic guidance all failed. Patient was eventually intubated using a retrograde wire-assisted fiberoptic intubation technique. At the end of procedure she was extubated over a tube exchanger without any untoward sequelae. Monday, October 14 10:30 AM - 12:00 PM FA MC687 Anesthetic Management in a Patient Status-Post Double Lung Transplant for Living-Related Donor Renal Transplant Caroline Hunter, M.D., Massachusetts General Hospital, Boston, MA A 51-year-old female with a history of cystic fibrosis complicated by insulin dependent diabetes respiratory failure status post bilateral living lobar lung transplant and end-stage renal disease secondary to diabetes and calcineurin inhibitor toxicity presented for renal transplant. The challenges we faced during anesthetic care included monitoring in the setting of a double lung transplant. We placed an arterial line and CVP catheter to monitor arterial blood gases and CVP respectively. Approximately 1 800 double lung transplants are performed annually in the United States and this operation causes anatomical and physiological changes that affects anesthetic management for subsequent operations. Monday, October 14 10:30 AM - 12:00 PM FA MC688 Difficult Airway Management in a Patient With Acromegaly and OSA Complicated by an Unexpected Supraglottic Mass Afzaal Iqbal, M.D., Zana Borovcanin, M.D., University of Rochester Medical Center, Rochester, NY A 52-year-old male with acromegaly and OSA presented for trans-sphenoidal pituitary tumor resection. During awake fiberoptic intubation a mobile polypoid mass was observed on the right vocal cord. With the endotracheal tube in place ENT attempted a biopsy with substantial manipulation. The patient was kept intubated and a tracheostomy was placed on POD#3 due to edema and ease of surgical exposure. An attempt to remove the mass failed one week later due to persistent edema. The mass was removed three months later with laser ablation once the edema subsided; the tracheostomy was then successfully decannulated. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC689 An Awake Malignant Hyperthermia-Like Death in a Patient Taking Dietary Supplements Johanes Ismawan, M.D., John Capacchione, M.D., Walter Reed National Military Medical Center, Bethesda, MD, Sheila Muldoon, Nyamkishig Sambuughin, Patricia Deuster, Uniformed Services University of the Health Sciences, Bethesda, MD A physically-fit 24-year-old female presented to the emergency department with tachycardia (HR 200) muscle rigidity and hyperthermia (105oF). Efforts to control her heart rate and temperature were unsuccessful: she died of multi-organ failure. She had a documented malignant hyperthermia (MH) event during surgery at age 11. Postmortem analyses identified a MH-causative RYR1 gene mutation (Gly2434Arg) and one month use of a weight-loss dietary supplement (OxyElite Pro) containing multiple stimulants. The pathologist identified caffeine and alcohol consumption as other contributing factors. It is possible that dietary supplements are a previously unknown risk for MH susceptible patients or persons with RYR1 mutations. Monday, October 14 10:30 AM - 12:00 PM FA MC690 Management of Massive Hemoptysis in the Bronchoscopy Suite: A Case Report Pankaj Jain, Paul Kempen, Cleveland Clinic, Cleveland, OH A 61-year-old female patient with a history of double lung transplant for Interstitial Pneumonia and subsequent declining pulmonary function underwent an outpatient transbronchial biopsy under sedation. She had no risk factors for hemorrhage. Following the fourth biopsy from the right middle lobe massive hemoptysis was noted with hypoxemia on the pulse oximeter. Emergent endotracheal intubation was performed and positive pressure ventilation was achieved. Hemostasis was subsequently achieved. Endotracheal intubation though potentially challenging is of utmost priority to optimize ventilation and oxygenation and for clearing the airway and hemostatic treatment of bronchial bleed. Monday, October 14 10:30 AM - 12:00 PM FA MC691 Anesthetic Management of a Patient With Hypokalemic Periodic Paralysis Undergoing Ascending Aortic Aneurysm Repair With Aortic Valve Replacement Vanita Jain, D.O., James Khoury, M.D., Baystate Medical Center, Springfield, MA A 56-year-old male with a history of hypokalemic periodic paralysis arrived for ascending aortic aneurysm repair and aortic valve replacement. Due to concern for hypokalemia causing prolonged paralysis and mechanical ventilation the goal of anesthetic management was to minimize the risk of hypokalemia. Normothermia was maintained throughout the case as hypothermia can cause intracellular shift of potassium. All intravenous fluids were free of dextrose and the patient was not given insulin intra-operatively to further reduce the risk of hypokalemia. Non-depolarizing paralytics were utilized and re-dosed at the surgeon's request. The patient was extubated without complications in the cardiac ICU. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC692 Perioperative Management of a Patient With Hemophilia A and Known Factor VIII Inhibitory Antibodies Undergoing Drainage of a Chest Wall Abscess Vanita Jain, D.O., Frederick Conlin, M.D., Baystate Medical Center, Springfield, MA A 48-year-old Hispanic male with a history of hemophilia A and factor VIII inhibitor antibodies arrived for chest wall abscess drainage. Because of his hemophilia and past history of hemorrhage we decided to transfuse factors prior to surgery. The standard prophylaxis for hemophilia A is to administer factor VIII however the patient had developed inhibitory antibodies to factor VIII rendering it useless. Instead factor VIII was by-passed and he received factor VIIa prior to surgery which was then tapered during the postoperative period. Intraoperatively he tolerated the procedure well with minimal blood loss. He was discharged home without complications. Monday, October 14 10:30 AM - 12:00 PM FA MC693 Successful Use of a Total Intravenous Anesthetic Technique for a Patient With Stiff Person Syndrome Undergoing Multilevel Posterior Lumbar Spine Surgery Jessica Jajosky, M.D., William Tippets, D.O., WVU, Morgantown, WV Stiff Person Syndrome (SPS) is an autoimmune disorder that affects GABA-ergic neurons and results in rigidity and spasms of axial muscles. Patients with SPS may experience postoperative hypotonia when exposed to volatile agents and muscle relaxants. In this case the patient underwent posterior lumbar surgery (L2-S1) for spinal stenosis and disc herniation. Her anesthetic included IV propofol remifentanil dexmedetomidine and ketamine. Neuromuscular blocking agents and volatile anesthetics were avoided. Agents acting via GABA receptors were minimized. Surgical conditions were adequate and the patient experienced an uneventful postoperative course. A TIVA technique may be a feasible option for patients with SPS. Monday, October 14 10:30 AM - 12:00 PM FA MC694 Intraoperative Diagnosis of a Tension Pneumothorax During a Laparoscopic Gastrectomy Zachary Jones, UT Houston, Houston, TX 92-year-old F with gastric cancer presenting for a robot assisted laparoscopic gastrectomy. She is highly functional at baseline with only a remote history of asthma and infrequent inhaler use. During surgery peak pressures increased from 20 to 30 and her blood pressure dropped from normotensive to 60s/40s. Breath sounds were absent over the left lung. The differential was right mainstem intubation mucous plugging bronchospasm and pneumothorax. Steroids and albuterol were given with no improvement. A bronchoscope confirmed ET tube above the carina and clear airways. Intraoperative CXR revealed left pneumothorax requiring decrease in insufflation and upgrade to ICU status. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC695 Extensive Thyroid Mass Encasing the Trachea to the Level of the Carina: Approach to Airway Management Julie Joseph, M.D., Lavinia Kolarczyk, M.D., University of North Carolina, Chapel Hill, NC A 77-year-old female presented with stridor and respiratory distress. CT scan revealed a large thyroid mass which encased the trachea and extended to the level of the carina. Significant mid tracheal narrowing (0.3 cm in smallest diameter) and tracheal deviation were noted. Approach to airway management included careful consideration of both upper and lower airway distortion mid tracheal narrowing and distal extent of the mass. Given the risk of airway collapse at multiple anatomic levels we performed an awake fiberoptic intubation using an extended length thin diameter endotracheal tube and electively intubated the right mainstem bronchus. Monday, October 14 10:30 AM - 12:00 PM FA MC696 Difficulties With Emergency Intubation in a Polymorbid Patient With Acutely Expanding Neck Hematoma Incision and Drainage Eduardo Jusino-Montes, M.D., Michael Tran, D.O., Paul Kempen, M.D., Cleveland Clinic Foundation, Cleveland, OH This 65-year-old male presented with stridorous respiratory distress from acute neck hematoma expansion after heparin intravenous infusion began in preparation for renal/hemo-ultrafiltration. He was admitted from an outside hospital for management of acute decompensated heart failure. His medical history included diabetes mellitus type II hypertension cerebrovascular disease thrombocytopenia pulmonary hypertension chronic kidney disease and dilated cardiomyopathy. Previous bilateral internal jugular venous catheterization attempts occurred under ultrasound guidance with normal coagulation studies except for thrombocytopenia (65K/mm3). Six hours after anticoagulant therapy began coagulation test results included an INR= 1.3 PT= 15.0 aPTT= >180 and platelet count (49K/mm3). Monday, October 14 10:30 AM - 12:00 PM FA MC697 Emergency Exploratory Laparotomy in a Patient With Recent NSTEMI and Bilateral Lung Transplant for Severe COPD and Pulmonary Hypertension John Kanaan, M.D., Cleveland Clinic Foundation, Rocky River, OH 63 year-old female POD#11 from bilateral lung transplant developed abdominal distention and leukocytosis with bowel pneumatosis on imaging; taken for emergent laparotomy. History: POD#9 developed AFlutter with RVR EKG changes in anteroseptal leads and positive cardiac enzymes. DC cardioversion produced sinus rhythm with return of R waves ST return to baseline and incomplete RBBB; troponin (peak 0.35ng/mL) decreased though still positive (0.23ng/ml) on POD#11. Echocardiogram obtained two days post-cardioversion demonstrated maintained LV function with resolution of pulmonary hypertension small pericardial effusion and dilated left atrium. History includes recent onset hyponatremia (126 mEq/L) schizophrenia hepatitis C hypertension and DM2 with neuropathy. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 10:30 AM - 12:00 PM FA MC698 Preoperative Volume Optimization Using Nitroglycerin in a Patient Scheduled for Pheochromocytoma Resection Armen Kara, M.D., University of Southern California, Los Angeles, CA Classically patients scheduled for pheochromocytoma resection are preoperatively started on adrenergic blockade however recent controversial studies have questioned the need for preoperative irreversible alpha blockade in normotensive patients. As such we have recently been encountering patients on the day of surgery that have little to no preoperative adrenergic blockade. We present one such patient whom we admitted the evening before scheduled adrenalectomy for pheochromocytoma in order to optimize her volume status using a nitroglycerin infusion. With this fluid optimization we were easily able to manage her vital signs intraoperatively without much fluctuation in her blood pressure throughout the entire case. Monday, October 14 10:30 AM - 12:00 PM FA MC699 Cleidocranial Dysostosis and Severe Refractory OSA: Challenges in Airway Management Marcin Karcz, M.D., M.S., Zana Borovcanin, M.D., University of Rochester, Rochester, NY 51-year-old morbidly obese male with cleidocranial dysostosis (CD) and severe refractory OSA was admitted for telegnathic maxillomandibular advancement (MMA) surgery. Airway exam showed a mouth opening only wide enough to visualize the tip of the tongue. After using a needle-less local anesthetic technique for airway topicalization an awake nasal fiberoptic intubation was performed. Postoperatively the patient was remained intubated due to the complexity of his surgery and significant airway edema. An approach to intubation and strategy for safe extubation of high risk patients with CD morbid obesity and severe refractory OSA undergoing MMA surgery will be discussed. Monday, October 14 10:30 AM - 12:00 PM FA MC700 Anesthesia Considerations of Deceptive Paradoxical Vocal Cord Motion Disorder Ami Karkar, M.D., Yi Hua, M.D., Georgia Regents University, Augusta, GA 64-year-old ASA III female with CLL mild asthma and HTN underwent a diagnostic laryngoscopy for left tonsillar mass. Patient tolerated the procedure well with general anesthesia intubated with a 7.0 mm endotracheal tube. After extubation with extubation criteria met she developed partial upper airway obstruction that presented with a rare intraoperative presentation of persistent gasping of air with 100% oxygen saturation and stable vital signs. Initially a trial of albuterol nebulizer positive pressure ventilation nasal trumpet placement IV epinephrine and racemic epinephrine were given. Fiberoptic laryngoscopy showed paradoxical vocal cord motion which was successfully treated with IV versed. Monday, October 14 10:30 AM - 12:00 PM FA MC701 Anesthesia Management of Patients With Parry-Romberg Syndrome Ami Karkar, M.D., Tao Hong, M.D., Georgia Regents University, Augusta, GA Parry-Romberg Syndrome (PRS) is a rare condition manifesting in severe progressive hemifacial atrophy involving skin soft tissue and bone. It is often found in the first decade of life more frequently in females. Copyright © 2013 American Society of Anesthesiologists It is known to cause severe facial pain and is associated with other auto-immune disorders and inflammatory changes noted on MRI (Moseley). Although many have studied its etiology and the complexities of surgical grafting the intraoperative anesthesia management of the multiple systems affected by PRS has not yet been studied. Consideration should be given to potentially difficult airways and connective tissue cardiovascular and neurologic aspects of PRS. Monday, October 14 10:30 AM - 12:00 PM FA MC702 Anesthetic Implications of Hypothyroidism Suzanne Kellman, M.D., Jennifer Hofer, M.D., The University of Chicago, Chicago, IL A 51F with interstitial lung disease is scheduled for a lung biopsy. She has a TSH level of 13 and symptomatic hypothyroidism. There are several possible perioperative implications of hypothyroidism including coma and cardiac arrest. Patients have increased peripheral vascular resistance decreased blood volume and impaired baroreceptor reflexes. Respiratory depressants specifically narcotics can lead to respiratory failure as both hypoxic and hypercapnic respiratory drives are decreased. The stress of surgery may unmask adrenocortical insufficiency requiring steroid supplementation. The degree of elevation in TSH corresponds to the severity of hypothyroidism. Properly diagnosed and treated hypothyroidism may mitigate these complications. Monday, October 14 10:30 AM - 12:00 PM FA MC703 Oesophagectomy in a Patient With Corrected Congential Cardiac Disease and Situs Invertus Catriona Kelly, M.B.Ch.B., Aoibhin Hutchinson, M.B.Ch.B., Royal Hospital, Belfast, United Kingdom A male patient presented for oesphagectomy two years after adulthood surgery for correction of congential cardiac disease. He was born with a single atrium and had two superior vena cavae draining into this. He also had situs invertus. He had atrial septation performed and his right SVC was reimplanted to the right atrium. He also had a mitral and tricsupid valve replacement. This case demonstrates the difficulties with managing venous access and one lung ventilation in a patient with altered anatomy and following successful cardiac corrective surgery.

Physical exam is significant for progressively decreasing upper extremity strength. MRI of the cervical spine shows central cord syndrome and neurosurgery plans an urgent posterior spinal fusion. Secondary to his injury we anticipate neurogenic shock and prepare for transvenous pacing. Roughly 5 min after induction patient became hypotensive to 70/40 and bradcardic to 45. Tapscope placed and paced until cardiology emergently came and placed a transvenous pacer. DP was paced for the next 40 min until his intrinsic heart rate surpassed the pacer. Monday, October 14 10:30 AM - 12:00 PM NA MC706 Staged Embolization Resection of a Carotid Body Tumor Geoffrey Lively, M.D., Pingle Reddy, M.D., Sarah Armour, M.D., Virginia Commonwealth University, Richmond, VA This is a 33-year-old female with bilateral carotid body tumors (CBT) left larger than right. Initially sixvessel cerebral angiogram with onyx embolization of the left carotid body tumor was performed. Anesthesia obtained ultrasound images pre and post embolization which correlated well to angiographic images of the CBT. The next day the patient returned to the operating room for CBT resection. Both procedures were performed under general anesthesia and utilized arterial line monitoring and somatosensory evoked potentials. No major fluctuations in blood pressure or reduction of evoked potentials were observed during either procedure. Monday, October 14 10:30 AM - 12:00 PM NA MC707 Management of Severe Intracranial Hypertension in Orthotopic Liver Transplantation Derek Lowe, M.D., Elizabeth Sunu, M.D., Ahmed Darwish, M.D., Eugenia Ayrian, M.D., University of Southern California, Los Angeles, CA Severe cerebral edema leading to intracranial hypertension (ICH) can be a lethal consequence of liver failure. A 25-year-old girl with acute liver failure and ICH was brought to the OR for liver transplantation. Preoperatively her MELD was 20 and intracranial pressures (ICP) in 30 mmHg range via bolt monitor. We focused on strategies to reduce ICP maintain cerebral perfusion pressure and reduce cerebral metabolic rate. Despite aggressive intraoperative efforts to control ICH her ICP remained in 40 mmHg range. However her cerebral edema resolved by postoperative day 2 and discharged on postoperative day 8 without neurological deficits. Monday, October 14 10:30 AM - 12:00 PM NA MC708 Complex Scoliosis Repair in a Toddler: A Case of Paraplegia With Normal Neuromonitoring Signals Morgan Mathie, D.O., Mary Herman, M.D., University of Florida, Gainesville, FL 2-year-old female with a history of VACTERL congenital anomalies including scoliosis cardiac anomalies including right sided arch ASD VSD anomalous pulmonary circuitry. Surgical repair was undertaken Copyright © 2013 American Society of Anesthesiologists somatosensory and motor evoked potentials were used. Throughout the duration of the case there was no loss of signals. Upon conclusion and during emergence it became apparent that the patient was no longer moving her lower extremities. An emergent CT was done showing a hematoma formation. She was taken back to the OR for revision. MEPs were absent prior to her revision upon opening the incision MEPs returned. Monday, October 14 10:30 AM - 12:00 PM NA MC709 Neuroprotection for Open Cerebral Aneurysm Clipping After Failed Coiling Caitlin McGinty-Froncek, M.D., Myles Boone, M.D., Beth Israel Deaconess Medical Center, Boston, MA 52-year-old male presented after mechanical fall with head trauma and positive LOC. CTA showed 1.6cm x 1.5cm aneurysm arising from the bifurcation of the right M1. After an unsuccessful endovascular coiling the patient was taken to the OR for an open clipping. Neuroprotective stratagies for open aneurysm clipping will be discussed including; cooling and pentobarbital coma. The patient was allowed to cool passively. Additionally a bolus of pentobarbital followed by an infusion was used to achieve burst suppression on EEG. Due to the pharmacokinetics of pentobarbital we were unable to obtain a neurologic exam concluding the surgery. Monday, October 14 10:30 AM - 12:00 PM NA MC710 Adenosine in the Setting of Refractory Hemorrhage of Cerebral Arteriovenous Malformation Carl McMullen, D.O., San Antonio Military Medical Center, San Antonio, TX We present a case of a 35-year-old otherwise healthy female who underwent a parietotemporal craniotomy for a symptomatic 3.5x3.0cm middle cerebral artery arteriovenous malformation. Anatomical position of the malformation and an inability to embolize it complicated the surgical resection which resulted in significant blood loss. Burst suppression was pharmacologically induced on multiple occasions during placement of temporary surgical clips. Despite multiple clips placed profuse hemorrhage continued from the surgical site. After discussion with surgeons adenosine was used to facilitate placement of more clips. Eventually recombinant factor VII was given to achieve definitive hemostasis. Monday, October 14 10:30 AM - 12:00 PM NA MC711 Decision Making in a Terminally Metastatic Cancer Maria Mendoza, M.D.,Theodore Marks, M.D., Rafi Avitsian, M.D., Cleveland Clinic, Cleveland, OH A 60-year-old male was emergently scheduled for relieve of spinal cord compression. His medical history was significant for hepatitis C with metastatic hepatocellular carcinoma and spinal stenosis with cauda equine syndrome. The patient was receiving enoxaparin for IVC thrombosis last dose given 6 hours before surgery. Before proceeding with the case Anesthesia and Surgical team explained to the patient the high risk of acute embolization and intraoperative death patient understood the risks but the most important thing for him was to be able to walk. We proceeded with the case the patient survived.

The literature has a robust description of the surgical approach but lacks discussion of the intraoperative physiological challenges of patients undergoing this rare and lengthy procedure. Here we describe our approach to the perioperative management of an opioid-tolerant T10 paraplegic undergoing a hemicorporectomy for refractory pelvic osteomyelitis. We discuss our anesthetic technique volume resuscitation strategy physiologic challenges and concerns and plan for postoperative pain control. Ultimately good communication with the surgeons and a strong understanding of the stages of the operation is essential. Monday, October 14 10:30 AM - 12:00 PM NA MC713 Mannitol Extravasation Leading to Compartment Syndrome John Patzkowsky, M.D., Xueqin Ding, M.D., University Hospitals Case Medical Center, Cleveland, OH A 58-year-old male with history of coronary artery disease diabetes mellitus and morbid obesity presented for craniotomy and resection of giant chondrosarcoma. He was placed in a semi-right lateral position requiring his left arm to be secured across his body. The surgeon requested mannitol administration which was infused through a 16-gauge IV catheter located in the left hand. Decreased SSEPs signals from the left upper extremity prompted discovery of a tensely swollen left hand with sloughing skin. After immediate discontinuation of the IV a diagnosis of compartment syndrome was made by orthopedic surgery who subsequently performed an emergent fasciotomy. Monday, October 14 10:30 AM - 12:00 PM NA MC714 Emergent Evacuation of Subdural Hemorrhage in a Patient With Acute Hemorrhagic Leukoencephalopathy Lauren Potts, M.D., Pedro Rios, M.D., Christopher Roberts, D.O., John Capacchione, M.D., Walter Reed National Military Medical Center, Bethesda, MD A 33-year-old female who presented with headache vomiting and left-sided weakness underwent a right frontal lobe biopsy of a lesion diagnostic for acute hemorrhagic leukoencephalopathy (AHLE) a rare disorder with an 80% mortality rate. On hospital day #29 declining mental status prompted head CT showing subdural hematoma worsening cerebral edema and developing uncal herniation. Emergent SDH evacuation with right frontal and temporal lobectomies required multiple blood products for ongoing hemorrhage and hemodynamic instability. This case illustrates the challenging management of a patient with AHLE as well as the ethical dilemma of surgical intervention for a patient with a poor prognosis.

Cerebral angiogram showed high grade stenosis of the left middle cerebral artery and a distal reconstitution by the collateral vasculature resulting in the characteristic Moyamoya disease findings. A superficial temporal artery to middle cerebral artery bypass was performed. Goals of maintaining normocarbia normothermia and hypervolemia should be prioritized. Unique challenges are prolonged burst suppression and tight blood pressure control needed to maintain optimum cerebral oxygen delivery. The key concepts are reviewed and possible improvements over our own anesthetic technique are suggested. Monday, October 14 10:30 AM - 12:00 PM NA MC718 When a Middle Cerebral Artery Aneurysm Ruptures Intraoperatively Sebastian Ramos, B.S., Shaheen Shaikh, M.D., University of Massachusetts Medical School, Worcester, MA 48-year-old healthy male sustained a mild concussion while working on his deck. CT revealed an incidental finding of a small cerebral aneurysm. He agreed for stent assisted coiling and was placed on Copyright © 2013 American Society of Anesthesiologists aspirin and Plavix. Intraoperatively the aneurysm ruptured with increased ICP that presented as severe hypertension bradycardia and pulmonary edema. Measures to reduce ICP were implemented. BP was elevated to maintain CPP once aneurysm was secured. Neurosurgery declined EVD since patient was on Plavix and placed a lumbar drain instead. Patient did not wake up postoperatively. Family agreed for organ donation after brain death criteria were met.

Differential diagnosis includes residual anesthetic narcotic overdose electrolyte abnormalities or ischemic events. Non-convulsive seizures as a cause of delayed emergence have rarely been described in the literature especially after non-neurologic cases. We present a case of a 36-year-old female with multiple comorbidities but no history of seizures who did not regain consciousness after a general anesthetic for amputation formalization. She did not display any outward signs of a seizure. After ruling out other causes of delayed emergence an EEG was obtained which showed she was in a non-convulsive status epilepticus state.

Past medical history also was significant for COPD ongoing tobacco abuse GERD and prior CVA. Preoperative TTE revealed a 47% EF and LV apical thrombus. Nuclear stress testing was aborted due to syncope; however resting images were consistent with prior infarct. Patient was admitted and treated with a heparin infusion until the day of surgery. Surgery was performed under general anesthesia. An arterial catheter was placed before induction. Patient did well postoperatively and was discharged home with appropriate follow-up on POD1. Monday, October 14 1:00 PM - 2:30 PM FA MC730 Anesthetic Management of Penetrating Cardiac Injury Peter Norstedt, M.D., University of Washington, Seattle, WA A healthy 28-year-old man was stabbed and airlifted to Harborview Medical Center. In the field SBP was 70 where he was intubated. Upon admission 2U PRBC were infused and a chest tube was placed with 200ml blood return. He was transported to the OR where general anesthesia was induced and laparotomy revealed hemoperitoneum and hemothorax. Further exploration demanded sternotomy and hemopericardium was found to originate from the ventricular apex. During repair the patient experienced ectopy followed by asystole. Cardiac massage and atropine resumed normal sinus rhythm. The remainder of the operation was unremarkable.

Dirk Younker, M.D., University of Missouri Hospitals and Clinics, Columbia, MO Relapsing polychondritis (RPC) is an inflammatory arthritis of cartilaginous structures including the tracheobronchial tree. We describe the case of a 22-year-old male with RPC presenting for operative fixation of a traumatic tibia fracture. The anesthetic plan was complicated by laryngotracheal involvement with 80% subglottic stenosis. The patient was asymptomatic but had no history of endotracheal intubation. His risk for intrathoracic and/or extrathoracic obstruction under general anesthesia was unknown. We elected to do the case under neuraxial anesthesia with a contingency plan for airway management. Monday, October 14 1:00 PM - 2:30 PM FA MC733 Management of Perioperative Hypotension in the Setting of an Undiagnosed Neuroendocrine Tumor. Tyler Pagel, M.D., Steve Hyman, M.D., Vanderbilt University Medical Center, Nashville, TN A 69-year-old male underwent general anesthesia for resection of a pre-sacral mass. He had hypertension treated with losartan. He developed intraoperative hypotension unresponsive to fluids but responsive to phenylephrine infusion. Pathology revealed a neuroendocrine tumor. Phenylephrine was weaned at emergence but resumed in PACU because of persistent hypotension and tachycardia. Somatostatin was considered but delayed pending final pathology. Phenylephrine was continued for approximately 24 hours postoperatively. The patient remained hemodynamically stable and was discharged home on POD#7. This case prompts discussion of perioperative hypotension in the setting of neuroendocrine tumors and possible ARB-induced vasoplegia.

The patient started to desaturate during emergence when switched to spontaneous ventilation. Endotracheal tube suctioning and 100% FiO2 was unsuccessful and patient was extubated. The tube was plugged with a thick mucus plug and patient was adequately mask ventilated. In this situation a rise in peak airway pressure did not alert us in detecting partial ET tube obstruction. We will go into the early recognition of this problem and available interventions for management of ET tube obstruction. Monday, October 14 1:00 PM - 2:30 PM FA MC743 Respiratory Obstruction After Thyroid Surgery Plus a Flood Neel Patel, Virginia Mason Medical Center, Seattle, WA 65-year-old female with thyroid papillary carcinoma causing left vocal cord paresis presented for a total thyroidectomy. Upon extubation from thyroidectomy patient experienced respiratory failure requiring immediate reintubation. During this time of respiratory failure the OR also began to flood with water due to sprinkler damage in nearby OR. Monday, October 14 1:00 PM - 2:30 PM FA MC744 Unusual Complication Preventing Guidewire Removal in Veno-Venous Bypass Catheter Placement Christopher Paul, M.D., Hui Yuan, M.D., Saint Louis University, St. Louis, MO In preparation for a liver transplant a veno-venous bypass catheter placement was attempted using the Seldinger technique. After placement of the catheter over the guidewire guidewire removal was attempted. After difficulty with removal ultrasound images were obtained. The guidewire appeared to be curled in on itself. It was decided to leave the guidewire in the catheter for the remainder of the case and other access was obtained. After the end of the procedure a venous cut-down was performed. The Copyright © 2013 American Society of Anesthesiologists guidewire was then easily removed with the distal end of the wire in a knot-like shape. No complications were noted. Monday, October 14 1:00 PM - 2:30 PM FA MC745 Trans-Orbital Tracheal Intubation of a Multiple Cancer Patient Alicia Pearce, M.D., John Eichhorn, M.D., University of Kentucky College of Medicine, Lexington, KY A 32-year-old F with her third cancer needed a full-mouth extraction prior to chemo-radiation therapy. Retinoblastoma as infant s/p enucleation radiation. Osteosarcoma of maxilla age 13 s/p excision radiation. New SCCA tongue. Orbit open directly to pharynx. Extensive radiation scars occluding nose severely limiting jaw opening prevented usual intubation. Following thorough evaluation and contingency planning (e.g. how to mask ventilate in emergency) awake intubation over a fiberoptic bronchoscope passed through orbit into trachea was accomplished. This challenging unusual intubation went smoothly and was fully documented photographically. Patient extubated next day. Case illustrates a creative approach that is widely applicable. Monday, October 14 1:00 PM - 2:30 PM FA MC746 Lidocaine-Based Opioid Free Anesthesia for Robotic Surgery in a CAD Patient Ana Cristina Pereira, M.D., Anna Lucia Rivoli, M.D., Renato Migon, M.D., Tania Carla Cortez, M.D., Paulo Sergio Lavinas, M.D., NCI Brazil (INCA), Rio de Janeiro , Brazil Minimally invasive procedures decrease injury response a especially important issue in CAD patients. We report a non-opioid based protective approach that potentiates such benefit. Male 66 85kg ASA 3 NYHA 2 history of CAD submitted to robotic-assisted Hartman surgery. Induction with dexmedetomidine 80 mcg lidocaine 600 mg MgSO4 3g propofol 100 mg rocuronium 90 mg; maintenance included dexmedetomidine 0.5 mcg/Kg/h lidocaine 1.5 mg/kg/h sevoflurane epinephrine 1-5 mcg/h. Postoperative period was uneventful including adequate non-opioid pain control and deambulation on day one. We conclude our lidocaine-based technique offered both cardiovascular protection and faster GI recovery due to the high lidocaine doses. Monday, October 14 1:00 PM - 2:30 PM FA MC747 Lingular Tonsilar Hyperplasia and Difficult Awake Nasal Fiberoptic Intubation Reid Phelps, M.D., Ph.D., Christopher Canlas, M.D., Vanderbilt University, Nashville, TN Patient was a 64-year-old female with a history of difficult intubation who presented for excisional biopsy of the base of the tongue. Our plan was for awake nasal fiberoptic intubation using dexmedetomidine for sedation. Patient was successfully intubated however vocal cords were poorly visualized. Biopsy demonstrated lingular tonsilar hyperplasia. Patient remained intubated postoperatively. On postoperative day 5 the surgical team attempted extubation despite evidence of persistent airway edema. Patient failed extubation with progressive dyspnea and stridor. ENT and intensive care teams were unable to reintubate and she was taken to the operating room for emergent tracheostomy. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 1:00 PM - 2:30 PM FA MC748 A Thousand Words: Examining the Utility of Photography in Clinical Practice Steven Price, M.D., Jason Hoefling, M.D., Georgetown University Hospital, Washington, DC A patient suffered an unavoidable perioperative dental injury to a tooth that was noted as very loose on preoperative assessment. Photography was used to document the necrotic nature of the tooth after its removal. This report examines the strategic use of digital photography in the practice of anesthesia. When employed with mind to HIPAA rules and regulations it can be a cost-effective method to aid in objectivity of potentially high-risk clinical findings improve anesthetic management and provide better evidence to refute prospective mediolegal claims. Monday, October 14 1:00 PM - 2:30 PM FA MC749 Paying Attention to EtCO2 During Laparoscopic Surgery Leads to Prompt Treatment and Prevention of a Possible Catastrophic Outcome Dritan Prifti, M.D. CCF, Brenda Lewis, M.D.CCF, Cleveland, OH 48-year-old F with PMH of Morbid obesity GERD Hx of Gastric banding brought to OR for Laparoscopic Roux en-Y. Induction and Intubation were uneventful. 15-20 minutes after incision time a sudden decreasse in EtCO2 was noticed. Prompt evaluation and communication with surgical team confirmed a bleed from inferior phrenic vein. Venous air embolism was suspected. Patient was stabilized. Procedure was converted to open Laparotomy for management of Accute blood loss/hemorrhagic shock and patient was transferred to SICU for hemodynamic support and mechanical ventilation. She was successfully extubated the next morning and discharged home in few days. Monday, October 14 1:00 PM - 2:30 PM FA MC750 Not a Simple EGD. Anesthetic Challenges of an Aortoesophageal Fistula. Aaron Primm, M.D., New York University, New York, NY A 91-year-old male with a history of CAD dyslipidemia HTN afib multiple AAA and thoracic aortic aneurysms with penetrating ulcers and ischemic colitis presented to urgent care with multiple episodes of hemetemesis. CT chest angiography with contrast suggested an aortoesophageal fistula and the patient was brought to the OR for EGD. An arterial line was placed before a modified rapid-sequence induction with glidescope intubation. EGD revealed a large posterior linear clot with active oozing in the mid esophagus with a pigmented protuberance suggestive of fistula. Patient remained intubated for airway protection and brought to the PACU hemodynamically stable. Monday, October 14 1:00 PM - 2:30 PM FA MC751 Severe Restrictive Lung Disease Complicating Robotic-Assisted Laparoscopic Prostatectomy Meghan Prin, M.D., Emily Vail, M.D., Ryan Ivie, M.D., Richard Raker, M.D., New York PresbyterianColumbia University, New York, NY We report the case of a patient with morbid obesity coronary artery disease dyspnea on exertion and prostate cancer who developed high peak inspiratory pressure a decline in tidal volumes hypercapnea and hypoxemia following steep Trendelenburg position and pneumoperitoneum for robotic-assisted Copyright © 2013 American Society of Anesthesiologists laparoscopic prostatectomy. The pulmonary disturbances resolved only on desufflation and return to supine position. The procedure was aborted. Subsequent cardiopulmonary testing revealed severe restrictive lung disease severe obstructive sleep apnea and moderate aortic stenosis. An open prostatectomy was recommended by the anesthesiologist and performed without pulmonary complications. Monday, October 14 1:00 PM - 2:30 PM FA MC752 Postoperative Hemiplegic Migraine: A Possibly Frightening Prospect Albin Quiko, Joseph Happel, M.D., Huy Phun, M.D., Amy Mortensen, M.D., Naval Medical Center San Diego, San Diego, CA We present a 36-year-old female who developed acute right sided total hemiparesis and hemi-sensory loss after an uneventful general anesthetic for laparoscopic cholecystectomy. Subsequent diagnostic studies were negative. The patient later endorsed a history of classic migraine headaches as well as an aunt and grandmother who had occurrences of hemiparesis lasting 2-3 days. Complete resolution occurred within 10 days and she was later diagnosed with familial hemiplegic migraines. Workup of frightening perioperative neurologic deficits must be done in a systemic manner to include an in-depth history and evaluation. This syndrome is not a simple diagnosis of exclusion. Monday, October 14 1:00 PM - 2:30 PM FA MC753 Airway and Anesthetic Management of Superior Vena Cava Syndrome Shuo Rainosek, M.D., Jill Irby, M.D., UAMS, Little Rock, AR A 51-year-old female with superior vena cava syndrome presented for percutaneous transluminal angioplasty of the innominate vein for symptomatic relief. The patient's chronic neck edema was complicated by acute stridor an inability to lay flat and vocal changes over the prior three days. Airway exam revealed Mallampati II mouth opening 2 centimeters and severe neck edema. The airway was anesthetized with a nebulized lidocaine updraft. Midazolam was given for sedation. Lidocaine and phenylephrine were applied to the left nasal cavity and dilatation was performed with nasal trumpets. Awake intubation was performed using flexible fiberoptic bronchoscope with a 6.5 ETT. Monday, October 14 1:00 PM - 2:30 PM FA MC754 Anesthetic Management for a Laryngeal Procedure in a Patient With Severe Posterior Glottic Stenosis Ramesh Ramaiah, M.D., F.R.C.A, Elizabeth Hankinson, M.D., Sanjay Bhanaker, M.D., F.R.C.A, University of Washington, Seattle, WA A 41-year-old female with severe posterior glottic stenosis from prolonged intubation presented for direct laryngoscopy and laser excision of scar tissue. CT scan showed the narrowest point of trachea to be 6mm x 8mm at glottic area. Surgeon requested that the patient remain spontaneously breathing for adequate surgical exposure. Patient was anesthetized with TIVA using low-dose propofol remifentanyl and ketamine infusions supplemented with superior laryngeal nerve block. The surgery lasted two hours. This anesthetic technique provided deep sedation adequate ventilation attenuation of sympathetic reflexes with excellent surgical exposure and reduced the risk of airway fire. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 1:00 PM - 2:30 PM FA MC755 Pulmonary Hypertension and Steep Trendelenburg Position for Robotically Assisted Laparoscopic Prostatectomy: Development of Hypoxemia and Right to Left Shunt John Raytis, M.D., Michael Lew, M.D., City of Hope, Duarte, CA A 73-year-old male with moderate pulmonary hypertension (PAP 55mmHg) presented for robotic prostatectomy. Two hours into the procedure the patient's oxygen saturation decreased acutely to 90%. After ruling out obvious causes for hypoxia an ABG was obtained on 100% FiO2 and showed 7.35/40/79/22 (A-a gradient 584mmHg) consistent with right-to-left intracardiac shunt. Desaturation resolved on removal from the trendelenburg position. Right-to-left shunt is a known cause for hypoxemia in non-surgical patients with pulmonary hypertension. In our case the development of the right-to-left shunt occurred intraoperatively and was likely brought on by the physiologic changes accompanying steep trendelenburg position and pneumoperitoneum. Monday, October 14 1:00 PM - 2:30 PM FA MC756 Challenges in the Management of a Mycotic Aneurysm of the Left Subclavian Artery Katie Reding, M.D., Harendra Arora, M.D., Priya Kumar, M.D., Kasey Fiorini, M.D., University of North Carolina, Chapel Hill, NC We describe a rare presentation of a mycotic aneurysm involving the left subclavian artery and its subsequent management that necessitated a collaborative team effort on the part of anesthesia vascular surgeons and cardiothoracic surgeons. A 21-year-old male patient with history of IV drug abuse presented with left elbow osteomyelitis two large brain abscesses and a left subclavian mycotic aneurysm. A left carotid to subclavian artery bypass graft was performed by the surgeons using a trap door approach.

No change in the pulse oximeter value was noted when varying the FiO2. Intraoperatively it was found that there was bilateral superior vena cava with the inferior vena cava in the midline. The anomaly was successfully repaired on bypass. The patient's post-CPB PaO2 was greater than 500 mmHg. Monday, October 14 1:00 PM - 2:30 PM PD MC779 Perioperative Management of a Patient With Rett Syndrome Hiromi Kako, M.D., David Martin, M.D., Richard Cartabuke, M.D., Joseph Tobias, M.D.,Nationwide Children's Hospital, Columbus, OH The patient was an 11-year-old 22.1 kilogram girl undergoing posterior spinal fusion for the treatment of progressive scoliosis. Her past history was significant for Rett syndrome with a seizure disorder and mental retardation; bronchomalacia and severe obstructive sleep apnea that required home bilevel positive airway pressure at night; insulin-dependent diabetes mellitus; and a prolonged QT interval. Preoperative physical examination revealed a cachectic girl with multiple joint contractures a Mallampati III view with limited mouth opening moderate micrognathia and limited range of motion of the neck. Perioperative management for the patients will be discussed and options for anesthetic care presented. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 1:00 PM - 2:30 PM PD MC780 Inability to Ventilate at Lung Re-Inflation During Pulmonary Segmentectomy in an Infant: A Review of the Challenges Associated With Single Lung Ventilation in Infants and Children Brian Keech, M.D., The University of Colorado, Denver, CO Single lung ventilation is highly desired by pediatric surgeons during more extensive pulmonary resections. However options for achieving this in pediatrics are limited. Our case involved a healthy 11 month old presenting for pulmonary segmentectomy. Lung separation was successfully achieved via fiberoptic intubation of the non-operative bronchus. Upon operative lung re-inflation we began experiencing progressive ventilatory difficulty ultimately requiring emergent re-intubation as a result of mucous plugging. This case illustrates that while lung separation can be reliably achieved in pediatrics lung isolation can't potentially exposing the non-operative lung to blood secretions and contaminated material at operative lung re-inflation. Monday, October 14 1:00 PM - 2:30 PM PD MC781 Perioperative Management of Partial Liver Resection for Metastatic Hepatocellular Carcinoma With Doxorubicin-Induced Cardiomyopathy and Recent Cardiac Arrest Christina Kendrick, M.D., Kai Schoenhage, M.D., Wallace Nogami, M.D., University of Arizona, Tucson, AZ A 14-year-old girl with recently diagnosed metastatic hepatocellular carcinoma presented for right hemihepatectomy. On pre-operative evaluation she was found to have an ejection fraction of 25-30% likely secondary to doxorubicin. Upon induction of anesthesia with propofol the patient developed ventricular tachycardia and became pulseless. She was successfully resuscitated and taken to the intensive care unit. Upon evaluation no clear etiology for her cardiac arrest could be elucidated. Echocardiogram and EKG were unchanged and CT of her chest was negative. Two weeks later the patient was brought back to the operating room and successfully underwent resection of her liver mass. Monday, October 14 1:00 PM - 2:30 PM PD MC782 Mycobacterium Avium Complex Presenting as a Mediastinal Mass in an 8 Month Old Infant Christina Kettelle, M.D., University of Arizona, Tucson, AZ This patient is an 8-month-old girl who at age 6 months was initiated four-drug therapy for presumed pulmonary mycobacterium tuberculosis. Her diagnosis was based on a positive PPD and a right middle lobe infiltrate. She presented to our institution after 2 months treatment with a worsening cough. Her cough was worse upon waking and when she was upset. She also experienced poor weight gain. Her CXR revealed a large anterior mediastinal mass which had caused a near collapse of the right bronchus and right middle lobe. Anesthesia was required for imaging and further diagnostic workup. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 1:00 PM - 2:30 PM PD MC783 Induction and Airway Management in an Infant With a Large Postcricoid Mass Maseeha Khaleel, Blake Hyde, Jennifer Adams, M.D., University of Nebraska Medical Center, Omaha, NE, Carol Lydiatt, M.D., Childrens Hospital of Omaha, Omaha, NE A postcricoid cushion is a normal but rare anatomical variant seen in-young children. A large cushion is rare and poses anesthetic complications. Cushions may engorge during agitation necessitating smooth mask induction with spontaneous ventilation. Preparation for emergent intubation or a surgical airway is required. After ablation or resection of the mass late postoperative swelling can occur and the need for intubation or prolonged mechanical ventilation may be needed to protect the airway. In this abstract we discuss a case report of an infant with a large postcrioid mass undergoing evaluation and a coblator procedure to decrease the mass size. Monday, October 14 1:00 PM - 2:30 PM PD MC784 Anesthetic Management of a Child With Pulmonary Arteriovenous Malformation Faiza Khan, Laura Moore, M.D., University of Arkansas for Medical Sciences, Little Rock, AR Pulmonary arteriovenous malformations (AVM)are caused by anomalous communications between pulmonary arteries and veins. These are mostly congenital in nature. They are usually diagnosed during the work up for hypoxemia and pulmonary nodules. We present a case of an 11-year-old child with Rendu Osler Weber syndrome presenting for embolisation of a symptomatic pulmonary AVM. He had a family history of similar syndrome and symptoms. Anesthetic care involves understanding the physiology of the shunt lesion along with managing the specific challenges of the pediatric patient. Monday, October 14 1:00 PM - 2:30 PM PD MC785 Neonate with Enlarged Neck Mass Diagnosed With Kasabach-Merritt Syndrome (KMS) - Perioperative Anesthetic Management and Implications. Sabina Khan, M.D., Nazish Hashmi, M.D., M.Saif Siddiqui, M.D., University of Arkansas for Medical Sciences, Little Rock, AR A 40 week Caucasian male was noted to have a large right neck mass at birth. It measured 5.4 x 4.5 cm on CT scan extending into the infratemporal fossa with compression effects. Labs demonstrated anemia and thrombocytopenia with coagulopathy. Diagnosis of KMS was established. Anesthesia service was consulted on 24th day of birth for definitive airway access due to concerns of impending airway compromise. Patient was successfully intubated and handed over back to the NICU team for further management. Monday, October 14 1:00 PM - 2:30 PM PD MC786 Anesthetic Challenges in a Patient With Prader-Willi Syndrome and Upper Respiratory Infection for Adenotonsillectomy: Intraoperative Pulmonary Hypertensive Crisis Sarah Khan, M.D., Joseph Tobias, M.D., Nationwide Childrens Hospital, Columbus, OH A 6-year-old with a BMI of 40 URI severe OSA asthma Prader-Willi syndrome increased RV pressures and ASD presented for adenotonsillectomy. Despite the high anesthetic risk her condition was felt unlikely to Copyright © 2013 American Society of Anesthesiologists improve. Toward the end of the case copious secretions were noticed in the endotracheal tube and there was profound bronchospasm. Simultaneously blood pressure was unattainable with a sudden decrease of the end-tidal CO2. Epinephrine boluses were administered an arterial cannula placed and a milrinone infusion started. Oxygen saturation remained in the 90's. Once stabilized she was transported to the PICU and extubated the next day to a BIPAP. Monday, October 14 1:00 PM - 2:30 PM PD MC787 Anesthetic implications of a Premature Infant With Pulmonary Interstitial Emphysema - Mainstem intubation With a Cause Ashish Khanna, M.D., Tara Hata, M.D., Cleveland Clinic Foundation, Cleveland, OH A 7-week (34 weeks PCA) infant with severe left sided Pulmonary Interstitial Emphysema presented for an endotracheal tube exchange & rigid bronchoscopy. Extensive cystic changes of the left upper lobe with significant mediastinal shift and lack of aeration of the right upper lobe were noted on radiology. As a part of a lung protective ventilation strategy oxygenation was maintained using a selective right main stem intubation. Anesthetic challenges included amongst others maintenance of spontaneous ventilation with intermittent apnea avoidance of positive pressure ventilation with mask (danger of mediastinal shift) apnea of prematurity & right upper lobe atelectasis with impaired oxygenation. Monday, October 14 1:00 PM - 2:30 PM PD MC788 Congenital Long QT Syndrome Was Unmasked by Accidentally Injected Epinephrine With Local Anesthetics Into Vein. Hae Kyu Kim, Hyeon Jeong Lee, Won Sung Kim, Eun Soo Kim , Pusan National University Hospital, Busan, Republic of Korea A 4-year-old female patient with normal ECG was scheduled for correction of velopharyngeal dysfunction. For hemostasis and clear local field 1% lidocaine with epinephrine (1:100000) was injected in soft palate and posterior of pharynx. At that time BP increased from 100/60 to 150/70 mmHg and HR rose from 113 to 175 bpm. Tachyarrhythmia was detected and esmolol was injected intravenously. After transfer to ICU pulmonary edema and ECG detected prolong QT (QTc 556 ms) were checked so she was tested in pediatrics and the result was congenital long QT syndrome. Monday, October 14 1:00 PM - 2:30 PM PD MC789 Frequent and Profound Anoxic Spell in Palliated TOF Infant During Thoracoscopic Thymus Cyst Removal Sang-Wook Shin, M.D., Hyae-Jin Kim, Seung-Hoon Baek, Eun-Jung Kim, Hee-young Kim, Pusan Nat'l Univ Hosp Anes & Pain Med, Yangsan-si, Republic of Korea A 3-month-old female baby was scheduled for thoracoscopic thymus cyst removal. She previously had palliative balloon valvuloplasty for tetralogy of Fallot (TOF). She had been well after the procedure and determined to be lower risk for thymus cyst removal before correction of TOF by consultation with cardiologist and surgeon. During the operation frequent and profound hypoxic spell occurred despite appropriate management CO2 retention was not improved. After surgery she was sent to intensive care unit. Frequent spell occurred in ICU. We found peripheral IV access was not functioning. Central line was kept she became stable gradually. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 1:00 PM - 2:30 PM PD MC790 Anesthetic Concerns for a Patient With Ebstein's Anomaly and Pectus Excavatum Scott Klier, D.O., Jani Jai, M.D., N. Nick Knezevic, M.D., Caroline Ryan, M.D., Advocate Illinois Masonic Medical Center, Chicago, IL We present the case of a four-year-old male undergoing bilateral myringotomy tube placement. Review of symptoms was positive for progressive exertional dyspnea and patient was noted to have severe pectus excavatum as well as a systolic murmur on physical exam. The patient's mother was unable to give any additional information on the child's medical condition with the exception of a history or repaired congenital diaphragmatic hernia. Further chart review revealed the patient had a known but untreated diagnosis of Ebstein's anomaly. The case was postponed to allow for a more thorough cardiac evaluation and patient optimization. Monday, October 14 1:00 PM - 2:30 PM PD MC791 Tetralogy of Fallot With Congenital Diaphragmatic Hernia and Left Lung Agenesis Kristen Labovsky, M.D., John Scott, M.D., Children's Hospital of Wisconsin, Milwaukee, WI A five-day-old female presented for repair of antenatal diagnosed congenital diaphragmatic hernia. An echocardiogram shortly after birth also revealed Tetralogy of Fallot and complete AV canal defect and a left pulmonary artery that was not visualized. Upon direct visualization during repair of the diaphragmatic hernia no left lung was identified. The repair was completed successfully and left lung agenesis was confirmed with CT angio that showed absence of a left pulmonary artery. The patient subsequently underwent placement of a central shunt on day 13 of life. Monday, October 14 1:00 PM - 2:30 PM PD MC792 A Neonate With Multiple Congenital Airway and Neurologic Abnormalities Causing Severe Respiratory Distress - Does this Strike a (noto) Chord? Susan Taylor, M.D., Kristen Labovsky, M.D., Children's Hospital of Wisconsin, Milwaukee, WI An eight-day-old neonate presented for evaluation of multiple airway anomalies including Pierre Robin sequence and a multilobulated mass of the palate and surgical repair of esophageal duplication cyst. Progressive airway obstruction occurred when moved from the right lateral decubitus position to supine for MRI. A 3.0 uncuffed endotracheal tube functioned as a nasopharyngeal airway for diagnostics and prior to surgery. Additional anomalies included an esophageal duplication cyst and anterior defects of the cervical and thoracic vertebral bodies. A meningocele at the craniocervical junction protruded anteriorly contributing to the neonate's upper airway obstruction. Copyright © 2013 American Society of Anesthesiologists MCC Session Number – MCC12 Monday, October 14 3:00 PM - 4:30 PM CA MC793 Re-Do OPCAB in Jehovah's Witness With ESRD Kara Siegrist, M.D., Robert Deegan, M.D., Ph.D., Vanderbilt University, Nashville, TN 68-year-old Caucasian male who presented for repeat off pump coronary artery re-vascularization. Case was complicated by patient's history of ESRD on HD anemia secondary to chronic kidney disease and platelet dysfunction secondary to uremia. The patient was a Jehovah's witness and refused blood products including those that may be life saving. Monday, October 14 3:00 PM - 4:30 PM CA MC794 Re-Do Off Pump Coronary Artery Bypass in Jehovah's Witness With End Stage Renal Disease Kara Siegrist, M.D., Robert Deegan, M.D., Ph.D., Vanderbilt University Medical Center, Nashville, TN A 68-year-old Jehovah's Witness presented for coronary revascularization. He had multiplerisk factors for bleeding: previous sternotomy (CABG) hemodialysis-dependent endstage renal disease and heparininduced thrombocytopenia. Surgery was postponed to ensure HIT-antibody negativity and resolution of anemia with erythropoietin treatment. The patient came to surgery with a Hct of 43. An OPCAB was performed with aminocaproic acid and DDAVP. Blood loss was 250cc with 150cc returned to patient via closed-loop cell-saver. Post-op a closed loop connection allowed chest-tube output to be returned to the patient. Hct remained >36% throughout hospital stay. Monday, October 14 3:00 PM - 4:30 PM CA MC795 Anesthetic Management of a Patient With Severe Constrictive Pericarditis which Required Emergent Cardiopulmonary Bypass Yoshihisa Morita, M.D., Koichi Nomoto, Mount Sinai School of Medicine, New York, NY 29-year-old male with history of suspicious tuberculosis underwent pericardiectomy for constrictive pericarditis involving all four cardiac chambers. Right atrium (RA) was exposed in case of urgent cardiopulmonary bypass (CPB). Subsequently he was emergently placed on CPB when several RA holes were accidentally made to free RA from adhesions. After weaning from CPB TEE revealed severe biventricular dysfunction requiring multiple inotropic supports. He became severely coagulopathic requiring multiple surgical packings and massive transfusion. Our case illustrates the importance to prepare for the massive bleeding before and after CPB for cardiac surgeries. Monday, October 14 3:00 PM - 4:30 PM CA MC796 Atrioesophageal Fistula After Percutaneous Radiofrequency Ablation for Atrial Fibrillation Jayanta Mukherji, Lisa Solomon, M.D., Ricky Shah, M.D., Loyola University Medical Center, Maywood, IL Atrioesophageal fistula (AEF) following RF ablation carries an extremely high mortality. Decreased awareness delayed diagnosis have resulted in increased mortality. 59-year-old male who underwent RF ablation one month prior presented with fever bacteremia.and cerebral embolic infarcts. Imaging Copyright © 2013 American Society of Anesthesiologists studies were unhelpful. Based on clinical suspicion he underwent surgical repair of AEF.. The case highlights a life-threatening delayed complication following AEF which necessitates prompt diagnosis and management. Multiple risk factors incriminated include RF catheter size power settings atrial anatomic sites. Anesthesiologists should insist on esophageal temperature monitoring as intraluminal esophageal temperature > 41 C can predispose to this complication. Monday, October 14 3:00 PM - 4:30 PM CA MC797 Previous Heparin-Induced Thrombocytopenia Does Not Preclude Heparin Anticoagulation Sagar Mungekar, M.D., Enrique Pantin, M.D., Robert Wood Johnson UMDNJ, New Brunswick, NJ A 56-year-old woman with severe mitral valve stenosis presented for valve replacement. Preoperatively her platelet count was below 100x10^9/L. Her past medical history was significant for heparin-induced thrombocytopenia (HIT) systemic lupus erythematosus and end-stage renal disease. Given the irreversibility of heparin alternatives a multidisciplinary decision was made to use heparin during extracorporeal circulation avoiding it before and immediately after. Postoperatively the patient's thrombocytopenia did not worsen; nor did she suffer any thrombotic events. We discuss the decision tree for choosing an anticoagulation regimen for patients with HIT and illustrate that with careful management heparin can still be safely administered. Monday, October 14 3:00 PM - 4:30 PM CA MC798 Elevated Airway Pressures and Inability to Ventilate on Cardiopulmonary Bypass During Aortic Valve Replacement Surgery Anand Nagori, M.D., Peter Neuburger, M.D., New York University, New York, NY 50-year-old female with history of hypertension hypothyroidism and childhood asthma underwent aortic valve replacement for aortic stenosis. Prior to coming off cardiopumonary bypass patient was difficult to ventilate. She was oxygenating well via bypass machine but attaining tidal volumes of 180 ml with peak airway pressures of 40 mm Hg. Fiberoptic bronchoscope was used to confirm tube placement and rule out mucus plugs. Epinephrine drip started intravenously and isoflurane was added via bypass machine. Albuterol 100 mg hydrocortisone and 30 mg ketamine were given for bronchodilation. Tidal volumes returned to 400 ml with peak pressures of 17 mm Hg. Monday, October 14 3:00 PM - 4:30 PM CA MC799 Anesthetic Management of Tricuspid Valve Replacement in a Patient With Metastatic Carcinoid Syndrome Faiz Nasser, M.D., Sean Summers, M.D., Benjamin Stam, B.S., Pramod Chetty, M.D., University of Oklahoma, Oklahoma City, OK Patients with metastatic carcinoid syndrome and carcinoid heart disease pose challenges to the anesthesiologist. Carcinoid crisis and low cardiac output states are of special concern. Octreotide has been used to prevent carcinoid crisis. We present a case of a 53-year-old male with metastatic carcinoid syndrome who underwent a tricuspid valve replacement for severe tricuspid regurgitation. Using a higher dose of octreotide than has been traditionally described in the literature along with intraoperative echocardiography and a balanced general anesthetic we were able to provide an Copyright © 2013 American Society of Anesthesiologists anesthetic experience free of carcinoid crisis or cardiac decompensation with successful separation from cardiopulmonary bypass. Monday, October 14 3:00 PM - 4:30 PM CA MC800 Ruptured Sinus of Valsalva Aneurysm in a 52-year-old Patient Thienkim (Kim) Ngo, M.D., Jae Park, M.D., University of Southern California, Los Angeles, CA Sinus of Valsalva aneurysms (SVAs) are rare anomalies that are usually congenital more frequent in men or acquired. We describe a case of ruptured SVA in a previously healthy 52-year-old man with sudden chest pain. Transthoracic echocardiogram identified the ruptured SVA from the noncoronary sinus into the right atrium (RA) and severe tricuspid regurgitation (TR). Using transesophageal echocardiogram we demonstrated the TR to be multidirectional flow from the aorta into the RA. The tricuspid and aortic valves were normal. The SVA was successfully repaired with primary suture closures and cardiopulmonary bypass was discontinued without inotropic or vasopressor support. Monday, October 14 3:00 PM - 4:30 PM CA MC801 Difficulty Weaning Off Cardiopulmonary Bypass: Role of Diabetic Cardiomyopathy Thomas Nguyen, M.D., Ahmed Zaky, M.D., M.P.H., University of Washington, Seattle, WA A 51-year-old male with a history of type I diabetes hypothyroidism obesity hypertension and smoking was taken to the OR for three-vessel CABG. Despite a preoperative EF>60% and successful revascularization he required high-dose pharmacologic inotropy intra-aortic balloon pump and LVAD to wean off cardiopulmonary bypass. Intraoperative echocardiography showed significant abnormality ofMyocardial motion in the longitudinal axis that was characteristic of diabetic cardiomyopathy. Postoperatively in the ICU hisMyocardial function continued to deteriorate. Ultimately he was moved to comfort care. In diabetics how well the myocardium functions longitudinally may be a better predictor than ejection fraction of survival following revascularization. Monday, October 14 3:00 PM - 4:30 PM CA MC802 Management of Anticoagulation and Vascular Access for Cardiovascular Surgery in a Patient With Heparin Induced Thrombocytopenia Alexandria Nickless, D.O., Elizabeth Sinz, M.D., Penn State Hershey Medical Center, Hershey, PA Heparin induced thrombocytopenia (HIT) is a rare but serious complication associated with the administration of heparin. Patients with this disorder experience an immune-mediated reaction ultimately leading to platelet aggregation and thromboembolic events. When anticoagulation is required usually for cardiovascular surgery alternative therapies must be used. A 57-year-old female with history of HIT vasculopathy end stage renal disease requiring hemodialysis and multiple thromboses presented with sepsis from infected subclavian bypass graft. This case presents the complicated management of a patient with difficult vascular access requiring anticoagulation for carotid-subclavian bypass. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 3:00 PM - 4:30 PM CA MC803 Failure to Deflate the Bronchial Blocker Stavroula Nikolaidis, M.D., Ali Hassanpour, M.D., Temple University School of Medicine, Philadelphia, PA Left lung isolation was achieved with placement of a Uniblocker in the left main stem bronchus with fiberoptic guidance. Upon surgeon's request attempt to deflate the blocker and reinflate the lung failed: lung still atelectatic after usual aspiration of the pilot balloon till flat. Bronchoscopy confirmed that the blocker stayed inflated obstructing the entry to the left main stem bronchus. How can we safely remove this blocker? How can we reinflate when placement of a new may not be quick easy or available. Monday, October 14 3:00 PM - 4:30 PM CA MC804 Cold Antibody in a Patient With Acute Type A Aortic Dissection Requiring Emergent Repair With Circulatory Arrest Stavroula Nikolaidis, M.D., Amol Patel, M.D., Temple University School of Medicine, Philadelphia, PA A 70-year-old female with history of diabetes and hypertension presented to the operating room for emergent repair of acute type A aortic dissection requiring circulatory arrest. Shortly after induction of anesthesia the blood bank notified us that they could not release blood because the patient was positive for a yet unidentified antibody. Suspicion was high for presence of cold antibody. The risks of hemolysis at low temperature antibody identification thermal amplitude time to blood availability were unknown yet. Should we wait for antibody identification and specific advice or proceed with emergent release of blood and cool circulatory arrest? Monday, October 14 3:00 PM - 4:30 PM CA MC805 Perioperative Treatment of a Man Receiving a Left Lung Transplant Combined With Coronary Revascularization Without Use of Extracorporeal Circulation Beatriz Nistal Nuno, M.D., Cesar Bonome Gonzalez, M.D., Ph.D., Complexo Hospitalario Universitario A Coruna, A Coruna, Spain Patients with significant coronary artery disease (CAD) were once traditionally rejected as candidates for lung transplants (LT) because of higher risk of morbidity and mortality. We report the case of a man who received a left LT and coronary revascularization without extracorporeal circulation (ECC) in a combined procedure after being diagnosed with significant CAD during the preoperative study for acceptance as a candidate for LT. We review the history of such combination procedures and discuss advantages of performing surgery without ECC. To our knowledge this is the first report of a combined procedure that took place in a Spanish hospital. Monday, October 14 3:00 PM - 4:30 PM CA MC806 A Unique Case of Bronchial Blocker Placement Gary Okum, M.D., Gregory Simmons,M.D., Drexel University College of Medicine, Philadelphia, PA New techniques and equipment for video assisted thoracic surgery enable the accomplishment of a broadening range of surgical procedures with less blood loss and postoperative pain than with classical thoracotomy. However the limited workspace available mandates separation of the lungs and renders Copyright © 2013 American Society of Anesthesiologists impractical the classically taught techniques for avoiding hypoxemia (particularly CPAP to the nonventilated lung). We report a challenging case of lung separation in a woman with a small stoma from previous tracheostomy in whom a small glottic opening had rendered futile the placement of both a double lumen tube and a size 7.0 single lumen tube. Monday, October 14 3:00 PM - 4:30 PM CA MC807 A Unique Case of Bleeding From the Pulmonary Artery Catheter Oximetry Connection Port Raja Palvadi, M.D., Raj Singh, M.D., Suman Rajagopalan, M.D., Baylor College of Medicine, Houston, TX Pulmonary artery catheters (PAC) malfunctions are rare and may pose a threat to patient safety. We present a case of a 57-year-old patient who underwent open repair of coarctation of aorta and pseudoaneurysm of the aorta. After the placement of the PAC cardiac output readings could not be obtained and fresh blood was noted to ooze from the oximetry optical module. The PAC was replaced without any complications. No external defects/tears were noted on close examination of the removed PAC. Further testing by Edward lifesciences revealed a tear in the webbing of the catheter which was due to manufacturing defect. Monday, October 14 3:00 PM - 4:30 PM CA MC808 Successful Use of Nitroglycerine Through the Pulmonary Artery Catheter PA Port to Treat Severe Pulmonary Hypertension Raja Palvadi, Khodadad Namiranian, M.D., Suman Rajagopalan, M.D., Baylor College of Medicine, Houston, TX Nitric oxide inhaled nitroglycerine inhaled milrinone and inhaled prostacyclins have been used to produce selective pulmonary vasodilatation. We report the successful use of nitroglycerine infused directly into the pulmonary artery through the pulmonary artery catheter to treat severe pulmonary hypertension. A 24-year-old male underwent emergent surgery with cardiopulmonary bypass to remove the dislodged Amplatzer device and repair of the ASD with pericardial patch. While attempting to wean from the CPB pump high pulmonary artery pressures were noted. Nitroglycerine was infused through the PAC which decreased the pulmonary artery pressure and facilitated the weaning from the pump. Monday, October 14 3:00 PM - 4:30 PM CA MC809 RVAD Placement for RV Rupture During Redo Sternotomy David Parisian, M.D., Joseph Goldstein, M.D., Dustin Hegland, M.D., Malcom Randall VAMC /University of Florida, Gainesville, FL 66-year-old male with CAD s/p 3V CABG and HTN presents for redo-sternotomy for AV repair for severe AS. During mediastinal dissection RV sustains a 3cm laceration and patient undergoes urgent fem-fem bypass. RV is repaired with pericardial patch and AV replaced. Patient is unable to separate from CPB with Inotropes and IABP; and TEE reveals poor RV contractility with large hematoma and hyper-dynamic LV. During separation attempts RA distends and CVP rises from 20 to 45. RVAD placement enables separation from CPB and coagulopathy from 11hr CPB run is corrected. RVAD is removed on POD #4 with improved RV contractility. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 3:00 PM - 4:30 PM CA MC810 To Bleed or Not To Bleed: An Alternative Approach to Intraoperative Management of Von Willebrand Disease During Mitral Valve Repair Roshan Patel, M.D., Seema Deshpande, M.B. B.S ., Caron Hong, M.D., M.S., University of Maryland, Baltimore, MD A 68-year-old male with Type1 von Willebrand disease underwent mitral valve repair for mitral regurgitation. Conventional guidelines recommend administration of DDAVP peri-operatively. However there have been instances of successful intra-operative management with von Willebrand factor concentrate when there is concern for variable severity of disease. Furthermore since decreased factor levels are a known cause of coagulopathy after cardiopulmonary bypass our goal was to minimize hemorrhagic complications in this high risk patient. The patient received 40-60IU of Humate-P after cardiopulmonary bypass and was transferred to ICU in stable condition. He required no additional blood products and was discharged home POD6. Monday, October 14 3:00 PM - 4:30 PM CA MC811 Pacemaker Failure During Anesthesia for Epicardial Lead Change in a Patient With Twiddler's Syndrome Stacy Peterson, M.D., Susan Taylor, M.D., Kristen Labovsky, M.D., Children's Hospital of Wisconsin, Milwaukee, WI A four-year-old male with Tetrology of Fallot pulmonary atresia and aortopulmonary collaterals suffered complete heart block following repair in infancy necessitating permanent pacemaker placement. The patient was diagnosed with Twiddler's syndrome 16 months prior to admission for repair of pacemaker leads. Recent interrogation demonstrated high impedance and the pacemaker was reprogrammed to generate maximum output. He had been asymptomatic and active during periods of pacemaker failure despite an idioventricular rhythm of 40. Following induction of anesthesia pacemaker failure to capture resulted in periods of asystole. A temporary transvenous pacemaker was placed. Monday, October 14 3:00 PM - 4:30 PM CA MC812 Resection of Posterior Mediastinal Mass Encompassing the Left Atria Phung Pham, M.D., Edward Gologorsky, M.D., Jackson Memorial Hospital, Miami, FL 19-year-old male with severe elevations in blood pressure and headaches. CT showed a subcarinal mass. He was medically optimized prior to surgery. The initial operation was an exploratory thoracotomy with planned resection. This surgery was subsequently abandoned as our intraoperative TEE showed that the mass encompassed the left atria. A second operation was planned with cardiac bypass. The surgeons were able to dissect a paragangliomia measuring 4 cm by 3cm. This case demonstrates the challenges of the perioperative management of neuroendocrine secreting mass and the challenge of an on-pump dissection of mass encompassing the left atria. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 3:00 PM - 4:30 PM CA MC813 Complex Mycotic Ascending Aortic Pseudoaneurysm Repair Complicated by Surgical Bleeding Biventricular Failure and Significant Post Bypass Coagulopathy Christine Piascik, M.D., Lavinia Kolarczyk, M.D., University Of North Carolina, Chapel Hill, NC Eight weeks after central V-A ECMO cannulation (and subsequent decannulation) for acute biventricular failure after CABG a 73-year-old male was incidentally found to have a large ascending aortic pseudoaneurysm (8 cm x 6.8 cm). Perioperative planning focused on risk of massive hemorrhage during complex revision sternotomy. Despite attempts to decompress the aneurysm by initiating axillaryfemoral cardiopulmonary bypass prior to sternotomy the aneurysm sac was inadvertently entered. Pump-sucker bypass provided short term stability until hypothermic circulatory arrest could be safely achieved. Post bypass course was complicated by biventricular failure and significant coagulopathy. Monday, October 14 3:00 PM - 4:30 PM CA MC814 Incidental Finding of Mitral Stenosis in a Patient Having Non-Cardiac Surgery Charles Poppell, M.D., Al San Juan, M.D., David Ruffin, M.D., Tripler Army Medical Center, Honolulu, HI 48-year-old Marshallese female with stage IV endometrial cancer was transferred for chemotherapy and en bloc resection of a large abdominal tumor. Her tumor burden caused large bowel obstruction and severe disability. Her course was complicated by incidental finding of severe mitral stenosis (mean gradient 25mmHg) and pulmonary hypertension (PASP 70-75mmHg). Percutaneous balloon valvuloplasty was complicated by atrial perforation and tamponade which required emergent sternotomy. Two weeks later a second balloon valvuloplasty was successful. Subsequently an exploratory laparotomy under combined general and epidural anesthesia proceeded without incident. This case illustrates the challenges of cardiac patients presenting for non-cardiac surgery. Monday, October 14 3:00 PM - 4:30 PM CA MC815 Catastrophic Intraoperative 3 Vessel Thrombosis Michael Queen, M.D., Baylor College of Medicine, Houston, TX, Bina Dara, M.D., Michael E. DeBakey VA Medical Center, Houston, TX A 61-year-old man with a history of mesothelioma and nonobstructive CAD was scheduled for left pneumonectomy. Two hours into the procedure the patient presented with intraoperative STEMI and cardiogenic shock. TEE confirmed severe wall motion abnormalities. The patient required large doses of pressors and cardiac massage. The surgery was aborted and following coronary angiogram the patient was transferred to the cardiac catheterization lab for an emergency multivessel PCI with bare metal stenting of the LAD LCX and RCA. These vessels were in spasm and contained thrombi. The patient was transferred to SICU on IABP and Abciximab.

His diagnosis included Hetrotaxy TGA TAPVR VSD and common atrium. Also he had abdominal situs inversus and biliary atresia. His room air SpO2 was 90's.We used standard ASA monitors arterial line and CVP monitoring. We administered general endotracheal tube anesthesia with balanced technique i.e isoflurane rocuronium and fentanyl. Regional techniques avoided due to coagulopathy. Patient lost 120 ml blood and received 60 ml PRBCs 50 ml FFP and 100 ml crystalloid during the surgery. Patient was successfully extubated at the end of surgery. Monday, October 14 3:00 PM - 4:30 PM CA MC817 Unusual Presentation of Hypoxia During Radiofrequency Ablation for Atrial Fibrillation Saima Rashid, M.D., Insung Chung, M.D., Mount Sinai Medical Center, New York, NY A patient with atrial fibrillation presents for intracardiac radiofrequency ablation under general endotracheal anesthesia. The patient became progressively hypoxic requiring recruitment maneuvers and 100% FiO2. An expanding pericardial effusion was noted on intracardiac echocardiography with increased vasopressor requirement. A percutaneous drain was placed in the pericardial space and continuous aspiration improved hemodynamics. An arterial catheter and large bore IV were inserted and blood products ordered. Blood was observed in the endotracheal tube. Fiberoptic bronchoscopy revealed bronchial bleeding which was treated with endotracheal epinephrine flushes and increased PEEP. A central line was inserted. Emergent exploratory mediansternotomy revealed a pulmonary artery perforation. Monday, October 14 3:00 PM - 4:30 PM CA MC818 High LVOT Gradient With Dobutamine After Septal Myomectomy Pingle Reddy, M.D., Sarah Armour, M.D., Derek Williams, M.D., Derek Brinster, M.D., Virginia Commonwealth University Medical Center, Richmond, VA 31-year-old male presented for septal myomectomy . His preoperative resting gradient was 34 mm Hg and peak gradient was 53 mm Hg. Following septal myomectomy patient was started on Dobutamine to elicit a gradient in the LVOT. Post resection peak gradient was determined to be 64 mm Hg. Tthe patient was also noted to have SAM of the AML. Dobutamine was stopped and the mean and peak gradients were determined to be 7 and 15 mm Hg respectively. This elicits the importance of determining LVOT gradients post induction under anesthesia and prior to septal myomectomy.

Monday, October 14 3:00 PM - 4:30 PM CA MC824 Anesthetic Management of 3 Patients With Electrical Storm Presenting for Emergent VT Ablation Tiffany Richburg, M.D., Nadine Odo, B.A., Mary Arthur, M.D., Georgia Regents University, Augusta, GA A higher prevalence of congestive heart failure has led to more implantable cardioverter-defibrillator (ICD) procedures and a higher incidence of electrical storm (10-20% of ICD recipients). This lifethreatening syndrome is defined as 3 or more sustained ventricular tachycardia (VT) episodes ventricular fibrillation (VF) or appropriate shocks from an ICD within 24 hours. Electrical storm can manifest duringMyocardial infarction in structural heart disease or an inherited arrhythmic syndrome. Outcomes are usually poor. During a VT storm episode patients' refractory to pharmacological treatment may present for emergent radiofrequency catheter ablation to treat the arrythmia. We present 3 patients undergoing this procedure. Monday, October 14 3:00 PM - 4:30 PM CA MC825 Pulse Oximetry Waveforms Analysis Vascular Tone and Chronic Fatigue M. Zundel, M.D., Medical College of Wisconsin, Milwaukee, WI, Matthias Riess, M.D., Ph.D., Clement J. Zablocki VA Medical Center, Milwaukee, WI Background: The pulse oximeter waveform represents vascular flow in the periphery. Physiologic parameters such as vascular compliance vascular tone stroke volume body size and the closing of the aortic valve all contribute to its shape. Case: An otherwise healthy 28-year-old male with a history of chronic fatigue and postural orthostatic tachycardia syndrome (POTS) presented for an MRI. Vitals were stable in the supine position (HR 76 BP 130/72) but upon standing he rapidly became tachycardic (HR 111). Pulse oximeter waveforms were abnormal and detailed waveform analysis provided valuable insight into the pathophysiology and cause of the syndrome. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 3:00 PM - 4:30 PM CA MC826 Anesthesia for an Adult Patient With Double-Inlet Left Ventricle With D-Transposition of Great Arteries Efrain Riveros-Perez, M.D., Cleveland Clinic, Woodmere, OH, Miguel Morillo, M.D., Nelson Ricardo Riveros-Perez, M.D., Cleveland Clinic, Cleveland, OH A 25-year-old male known to have a double-inlet left ventricle D-transposition of the great arteries and severe pulmonary hypertension is presented. Lost to follow-up since infancy the patient returns due to functional capacity deterioration. The echocardiogram showed a double-inlet left ventricle and anterior semilunar valve giving origin to the coronary ostia and a small atrial septal defect. Right heart catheterization revealed elevated pulmonary resistance and good vascular reactivity. The patient underwent pulmonary artery banding and atrial septostomy. General anesthesia was administered based on meticulous balance between peripheral and pulmonary resistance to avoid pulmonary overflow and systemic hypoperfusion. Monday, October 14 3:00 PM - 4:30 PM CA MC827 Anesthetic Management of Emergency Laparoscopy in an Adult With Fontan Physiology and Situs Inversus Kathryn Rosenblatt, M.D., Nurudin Cemer, D.O., Nadia Nathan, M.D., SUNY Upstate Medical University, Syracuse, NY Improved surgical technique is increasing the population of CHD survivors with myriad structural abnormalities. We present a 23-year-old female with Fontan physiology and situs inversus requiring emergency laparoscopy for acute abdomen. She is status post multi-stage univentricular palliation for hypoplastic LV double-outlet RV and spinal fusion for scoliosis. Laparoscopy has potential for hypotension and hypoxemia in Fontan patients; emergent surgery adds risk with little time for hemodynamic optimization. A delicately tailored plan integrating different anesthetic considerations was implemented despite limited pre-operative information. Continuous communication between surgeons and anesthesiologists especially concerning insufflation allowed smooth and tight control of her complex physiology. Monday, October 14 3:00 PM - 4:30 PM CA MC828 Not for the Faint-Hearted: Anesthesia for Revascularization in Patient With Takayasu's Arteritis Alecia Sabartinelli, M.D., Edward Gologorsky, M.D., University of Miami Miller School of Medicine, Miami, FL A 23-year-old female presented with sudden onset syncope transient weakness vision changes and absent radial pulses. Work-up revealed Takayasu's arteritis with severely compromised flow within the bilateral carotid brachiocephalic and left axillary arteries. Treatment plan included corticosteroids administration followed by aortic debranching with grafts bypassing areas of occlusion. Approach was planned via interdisciplinary consultations among the vascular cardio-thoracic and anesthesia services with provisions made for possible cardiopulmonary bypass and deep hypothermic circulatory arrest. Complete revascularization with GorTex grafts was achieved utilizing ascending aortic partial crossclamp beating heart and INVOS and EEG monitoring. Patient was extubated in the OR neurologically intact.

Anesthetic management goals of these patients should include interventions to improve right ventricular contractility and avoid increases in RV afterload. Placement of PA catheter can be technically difficult and care should be taken to avoid arrhythmias. TEE can accurately identify the lesion its severity and associated cardiac defects. Intra-operative TEE is a valuable tool to help guide intravenous fluid therapy and pharmacologic interventions by assessing the right and left ventricular preload and changes in ventricular function. Monday, October 14 3:00 PM - 4:30 PM OB MC830 Considerations for Neuraxial Anesthesia for Cesarean Section in the Setting of Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy (CADASIL Syndrome) Abhinava Madamangalam, M.D., Robert Schoaps, B.S., University of Oklahoma Health Sciences Center, Oklahoma City, OK A patient with CADASIL Syndrome presented to us for Cesarean section at 38-weeks gestation with a history of cerebral artery occlusion and residual left-sided sensory deficits. The patient demonstrated allodynia of her left hemibody. The pregnancy was otherwise uncomplicated.

Patient received combined spinal/epidural for anesthesia. Baby was delivered without complication. Eventually what was thought to be a placenta accreta turned out to be percreta. Surgery was complicated perfuse bleeding was encounterd and patient was converted to general anesthesia. Massive transfusion protocol was initiated. Resuscitative efforts were driven by the information gained from ABG's and TEG. Our goal is to emphasize the importance of utilizing these modalities to guide resuscitation in a massive blood loss situation. Monday, October 14 3:00 PM - 4:30 PM OB MC833 Idiopathic Intracranial Hypertension and Pregnancy Zafar Siddiqui, M.D., Tanya Lucas, M.D., UMass Memorial Medical Center, Worcester, MA A 25-year-old G1P0 at 24 weeks pregnant presented with visual changes headache and marked papilledema. She had no hypertension proteinuria mass lesion or CSF pathology. She did have an ICP of 55 cm H2O and a diagnosis of idiopathic intracranial hypertension was made. She had 2 lumbar punctures for CSF drainage to decrease ICP and thus the chance of permanent sequelae including blindness. She was placed on acetazolamide with resolution of her symptoms and papilledema prior to discharge. Presently the plan is for NSVD if she remains asymptomatic. Her delivery is imminent and an early epidural is recommended. Monday, October 14 3:00 PM - 4:30 PM OB MC834 Pregnant Patient With a Large Anterior Mediastinal Lymphoma Loveleen Sikka, M.D., Steven Shulman, M.D., Lawrence Chinn, M.D., UMDNJ, Newark, NJ Perioperative management of patients with an anterior mediastinal mass (AMM) is an anesthetic challenge. We describe the management of a patient who is 14 weeks pregnant with a massive AMM causing superior vena cava syndrome requiring thoracic biopsy and later D&C in order to begin chemotherapy. Chest CT showed compression of the carina and both mainstem bronchi. Incisional biopsy was performed under ketamine and local lidocaine. That evening the patient reported hallucinations and anxiety. Four days later D&C was performed under saddle block with dexmedetomidine infusion and midazolam. The patient remained hemodynamically stable and maintained spontaneous respirations throughout both procedures.

Sean Ohanian, M.D., Beaumont Health System, Royal Oak, MI A 24-year-old pregnant female with a past medical history of Mustard procedure for childhood correction of d-TGV presented for dilation and evacuation. The anesthetic risk for this patient was significantly increased by the fact that she had CHF severe pulmonary edema and cardiac arrest complicating her previous pregnancy. Subarachnoid block was initiated in an effort to reduce right ventricular strain and cardiac morbidity. An increasing number of patients with corrected TGV now survive to adulthood with the accompanying increased risks of anesthesia. Anesthetic management in this patient with d-TGV and its physiologic implications are discussed. Monday, October 14 3:00 PM - 4:30 PM OB MC839 Does the Patient REALLY Need a Blood Patch? Panthea Taghizadeh, M.D., John H. Stroger Jr. Hospital of Cook County, Chicago, IL A 24-year-old female with a history of polysubstance abuse status post spontaneous vaginal delivery under epidural analgesia was readmitted complaining of a non-positional headache. Pain service was consulted for possible blood patch. Detailed history and physical examination revealed signs of meningismus. Based on clinical evaluation additional diagnostic work up was requested and proved negative for infectious etiology. Within 48 hours patient developed a seizure with a resulting brain MRI revealing sub-acute infarcts. This raised the concern for an underlying vascular etiology such as postpartum cerebral angiopathy. Patient fully recovered after recommended treatment with vasodilators and steroids.

Prior to admission the patient suffered multiple myasthenia crises requiring tracheostomy and PEG tube and trials of high dose steroids Mestinon IVIG plasmapheresis and Rituxan. Epidural anesthesia was administered successfully by gradually dosing 2% lidocaine with 1:200 000 epinephrine. The patient also received a dose of stress steroids and antiepileptic for seizure prophylaxis. The procedure was tolerated well with delivery of a live baby. On post-operative day 5 she developed a suspected myasthenia crisis. Monday, October 14 3:00 PM - 4:30 PM OB MC846 In the Right Place at the Right Time Dan Trinh, M.D., University of Connecticut Health Center, Middletown, CT A 32-year-old 29-weeks pregnant female was visiting her husband in the hospital ED. While there she developed severe abdominal pain coinciding with hypotension and fetal bradycardia. A STAT C-section was called. After induction of general anesthesia and surgical exposure massive intraabdominal bleeding was discovered. After rapid delivery of the baby the surgery team became emergently involved while continuous blood product and hemodynamic support were provided. The patient was diagnosed with a ruptured splenic artery aneurysm and required splenectomy and vessel ligation. The mother and baby survived. If not for being in the hospital mortality is usually significant for both. Monday, October 14 3:00 PM - 4:30 PM OB MC847 How Low Is Too Low? Thrombocytopenia and Spinal Anesthesia for Caesarian Section Matthew Ufberg, M.D., Sumita Bhambhani, M.D., Temple University Hospital, Philadelphia, PA, Ari Bensimhon, , Student, Temple University School of Medicine, Philadelphia, PA A 37-year-old G8P6016 female with two prior C-sections presented at 36 weeks for scheduled Cesarean. PMH was notable for morbid obesity (BMI 50) and recently developed large thyroid mass. She also had developed thrombocytopenia with platelet count of 46 000 at her office visit. On the day of scheduled Cesarean she was transfused two pools of cross-matched platelets. Despite this her platelets fell to 33 000. Given the likelihood for difficult airway and lack of bleeding bruising or petechiae decision was made to administer spinal anesthesia. Spinal and subsequent operation proceeded without incident. The patient delivered a healthy baby without post-operative complications. Copyright © 2013 American Society of Anesthesiologists Monday, October 14 3:00 PM - 4:30 PM OB MC848 Anesthesia Managment of a Patient With Fibrosing Mediastinitis in Labor Aruna Vaddadi, Jaya Ramanathan, M.D., University of Tennessee Health Sciences Center, Memphis, TN Fibrosing mediastinitis (FM) causes excessive fibrotic reaction in mediastinal structures airways and great vessels. Common etiology is histoplasmosis and immune response (HLAA2). A multigavida with five years history of severe FM underwent cesarean section. A combined spinal-epidural anesthesia was administered successfully. Her postpartum course was uneventful. FM presents as granuloma with leakage of fungal antigen causing fibrosis of mediastinal structures with V/Q mismatch hypoxemia pulmonary hypertension and pulmonary edema aggravated by increased blood volume in pregnancy. General anesthesia may be associated with difficult ventilation and oxygenation. Regional anesthesia is the anesthetic of choice in pregnant patients with fibrosing mediastinitis. Monday, October 14 3:00 PM - 4:30 PM OB MC849 Anesthesia Management and Inflammatory Profiles of an Obstetric Patient With History of GuillainBarre Syndrome Ivan Velickovic, M.D., Lin-Lin Wang, B.S., Giorgio Medranda, B.S., Ming Zhang, M.D., Ph.D., SUNY Downstate Medical Center, Brooklyn, NY Guillian Barre syndrome (GBS) is a rare autoimmune neuropathy characterized by systemic inflammation as indicated by activation of complement factors. A 38-year-old woman G2P1 with a previous history of GBS had Cesarean Section under GA (patient refused any regional anesthetic). Complement factors in maternal and fetal cord blood were analyzed. MBL of the lectin complement pathway was deficient in both the maternal and fetal circulation while the factors of the other 2 complement pathways were intact. Thus it is likely that the autoimmune response in GBS involves classical and alternative pathways of complement but not the lectin pathway. Monday, October 14 3:00 PM - 4:30 PM OB MC850 Anesthesia Management of a Morbidly Obese Parturient Going for Caeasarean Section With Coronary Artery Disease and Recent Stent Placement Catherine Vu, M.D., Jennifer Hochman, M.D., Jayanthie Ranasinghe, M.D., Jackson Memorial Hospital, Miami, FL Cardiac disease is one of the leading causes of maternal mortality. However the prevalence of coronary artery disease is uncommon among parturients (incidence of 1:10 000). We present a case of a 40-yearold G4P1203 at 34 weeks BMI of 60 Mallampati score of 4 diabetic preeclampsia superimposed on chronic hypertension coronary artery disease with placement of two bare metal stents after a NSTEMI and immediately before the current pregnancy currently on plavix presented to the labor floor for an urgent c-section.

We present a case of a morbidly obese 25-year-old G6P0232 at 37 and 4 weeks carrying a fetus with LQTS. The patient was admitted with pre-eclampsia and posted for urgent cesarean section. Careful consideration was made regarding her anesthetic plan to avoid drugs that could precipitate life-threatening arrhythmias. A combined spinal-epidural technique was utilized with co-loading of IV fluid to maintain maternal blood pressure. The baby was safely delivered and transferred to the NICU in stable condition for further management. Monday, October 14 3:00 PM - 4:30 PM OB MC852 Optimization of Fetal and Maternal Outcomes During an Urgent Cesarean Section on a Preterm Parturient With Congenital Transposition of Great Vessels and Complex Single Ventricle Physiology Jeremie Walker, Richard Driver, David Rosen, WVU, Morgantown, WV The 36 week and 1 day preterm parturient in this case required an urgent cesarean section for nonreassuring fetal heart tones. At 22-year-old she had significant cardiac history including transposition of great vessels and a complex single ventricle physiology. In addition the husband had transposition of great vessels. With initial resistance from the patient for an awake cesarean section we delivered a healthy infant after placing an epidural awake arterial line awake central line and relocating the patient from the obstetric unit to the pediatric cardiac operating suite for unexpected intra-operative complications that might require emergent intervention. Monday, October 14 3:00 PM - 4:30 PM OB MC853 Bezold-Jarisch Reflex and Seizure Observed During Acute Hemorrhage in a Cesarean Section Cindy Wang, M.D., Edward Mathney, M.D.I, Icahn School of Medicine at Mount Sinai, New York, NY A 32-year-old gravida 3 woman at 38 weeks gestation in active labor presented for a tertiary Cesarean section with epidural anesthesia. After delivery of a healthy infant the patient became unresponsive severely bradycardic and hypotensive with brisk bleeding from a transected artery. Aggressive resuscitation and arterial ligation resulted in quick hemodynamic recovery but neurologic alteration persisted. This episode of hemorrhage and sympathetic blockade likely incited a Bezold-Jarisch reflex and revealed an underlying seizure disorder. This case suggests that hemorrhage in the setting of neuraxial anesthesia may incite a Bezold-Jarisch reflex and uncover other co-existing diagnoses in obstetric patients.

TTE was unavailable. Decision made to deliver for severe preeclampsia with complicating pulmonary edema and ARI. Postoperative echo revealed LVEF of 17%. Monday, October 14 3:00 PM - 4:30 PM OB MC857 Altered Mental Status During Labor Secondary to Hyponatremia Steven Wright, M.D., Frank Jaime, M.D., Lev Deriy, M.D., University of New Mexico, Albuquerque, NM A 33-year-old female began having altered mental status 36 hours after admission for delivery. Concern for intracranial etiology required urgent cesarean section performed under general anesthesia because of potential increased intracranial pressure and patient's inability to cooperate with neuraxial Copyright © 2013 American Society of Anesthesiologists techniques. After induction arterial blood gas demonstrated sodium level of 118 Meq/L. Patient remained intubated in the ICU postoperatively. Hyponatremia was self-corrected within 12 hours and the patient was extubated without neurologic sequelae. Etiology was determined to be caused by increased production of ADH from prolonged labor in the setting of a large ingestion of water. Monday, October 14 3:00 PM - 4:30 PM OB MC858 Anesthetic Management for Cesarean Section in a Parturient With Moyamoya Disease Jijun Xu, Matvey Bobylev, Cleveland Clinic, Cleveland, OH Anesthetic management for cesarean section (CS) in a 29-year-old parturient with Moyamoya disease (MMD) is discussed. Pre-induction arterial line placed and IV fluids given. Anesthesia maintained with slow epidural anesthesia induction and intermittent IV boluses of fentanyl. Systolic blood pressure was maintained using LUD IV fluids and phenylephrine boluses to preserve adequate cerebral perfusion.

Patient received a standard induction dose of etomidate and succinycholine. Patient had no twitches or muscle strength for about an hour and half after induction. Patient was suspected to have a PC deficiency and dibucaine labs were sent off. Monday, October 14 3:00 PM - 4:30 PM OB MC862 Anesthetic Management of Labor Analgesia for a 27-year-old Female With New Onset Pituitary Macro Adenoma Caleb Zelenietz, M.D., Brian Gregson, M.D., University of Manitoba, Winnipeg, MB We describe the anesthetic management of labor analgesia for a 27-year-old female with new diagnosis of pituitary macro adenoma. The patient was a previously healthy primigravida developing new onset headaches during the second trimester of pregnancy. Bilateral visual field defects onset in the third trimester prompting her to be diagnosed with pituitary macro adenoma. She was unsuccessfully treated with dopamine agonists. After consultation with neurology and neurosurgery it was decided to induce labor at 36 weeks gestation. She underwent epidural analgesia for vaginal delivery without complication. Post partum she underwent neurosurgical resection of her pituitary macro adenoma. Monday, October 14 3:00 PM - 4:30 PM OB MC863 Anesthetic Management for a Parturient with Arnold-Chiari and Tethered Cord Syndrome Eric Zelman, M.D., Jong Lee, M.D., Amol Patwardhan, M.D., Ph.D., Kai Schoenhage, M.D., University of Arizona, Tucson, AZ Our case report describes the anesthetic management of a 35-year-old parturient with both a previous occiput to C5 cervical fusion and a tethered cord release. She was scheduled for an elective caesarean section and was referred to the pre-operative anesthesia clinic by her obstetrician and neurosurgeon. Multiple anesthetic options were discussed and the patient ultimately elected and tolerated a single shot spinal. The main learning points from this case come from the preparation involved the variety of contingency plans and the vigilance of the pre-operative assessment. Monday, October 14 3:00 PM - 4:30 PM OB MC864 PostpartumTransient Focal Neurological Deficit Related to Hypoglycemia Liang Zhang, M.D., M.S., Banu Lokhandwala, M.D., Jun Lin, M.D., Ph.D., SUNY Downstate Medical Center at LICH State University of New York, Brooklyn, NY 36-year-old G2P1 underwent repeat C-section with CSE. On POD 2 patient developed fever dysarthria left facial droop with right lower extremity weakness. CT head MRA and MRI (head and full spine) were negative. LP yielded negative chemistry and bacterial panel. U/A showed positive ketone without WBC. Blood culture was negative. Neurological deficits were reported when blood glucose dropped from 65 mg/dl to 49 mg/dl on POD2 and were completely resolved on POD3 when blood glucose was 112mg/dl. Copyright © 2013 American Society of Anesthesiologists We hypothesize that hypoglycemia induced by long fasting and worsened by postpartum endometritis led to the acute focal neurological deficits.

Craig Samford, M.D., Arpad Zolyomi, M.D., University of New Mexico, Albuquerque, NM Meige's syndrome is a rare dystonia comprised of blepharospasm and involuntary movements of the face jaw and neck muscles. Severe symptoms lead to difficulties with speaking eating and drinking and social isolation. Systemic medications and botulinum toxin injections are often ineffective. We present a case of deep brain stimulator implantation in a patient with a five-year history of medically refractory Meige syndrome. Microelectrode recordings could not be interpreted due to severe craniofacial dystonia. During remifentanil infusion the dystonia improved and the microelectrode recordings became useable for guidance. Tuesday, October 15 8:00 AM - 9:30 AM NA MC866 Management of Parturient With Ruptured Grade IV Arteriovenous Malformation Christopher Schrock, M.D., Russell Langdon, M.D., University of Tennessee Medical Center, Knoxville, TN A parturient with a history of an arteriovenous malformation presented to the hospital with a sudden headache that rapidly progressed to loss of consciousness. Computed Tomography was consistent with a ruptured AVM resulting in a large hemispheric intracranial hemorrhage. She was emergently taken to the operating room for a decompressive craniotomy. Afterwards she was monitored in the ICU for several days until ultimately being taken back to the operating room for staged endovascular embolization of her AVM. On the 23rd hospital day she was discharged to a rehabilitation facility with neurologic deficits including dysphagia expressive aphasia and right hemiparesis. Tuesday, October 15 8:00 AM - 9:30 AM NA MC867 Perioperative Management of a Large Highly Vascularized Metastatic Cervical Spine Tumor With Dislocated Spine and Severe Spinal Cord Compression Milad Sharifpour, M.D., M.S., Oleg Evgenov, M.D., Ph.D., Massachusetts General Hospital, Boston, MA Surgical management of spine metastases is associated with life-threatening blood loss and significant morbidity and mortality. A 54-year-old male presented with a large highly vascularized C4-T1 metastatic renal cell carcinoma with complete anterior cervical spine listhesis and severe spinal cord compression. Posterior instrumentation/debulking was attempted but terminated due to a 10.2L blood loss.A Halo brace was placed. Following chemotherapy/radiation the patient underwent tumor embolization followed by anterior cervical corpectomy with fusion. During the 16-hr procedure blood loss was 8L requiring administration of blood products and intravenous fluids through a rapid infuser. He was ultimately discharged following rehabilitation therapy.

Recently vagal nerve stimulation has been investigated as a treatment for heart failure where sympathetic dysregulation plays a significant role in the disease pathogenesis. This experimental procedure required perioperative coordination between surgeon cardiologist electrophysiologist and anesthesiologist. Preoperative anesthetic evaluation emphasized the characterization of heart failure management of the pacemaker and building rapport with an anxious patient. Perioperative goals included minimizing sympathetic stimulus hemodynamic support and management of arrhythmias and fluids. Certain precautions were taken and procedural phases anticipated by the anesthesiology team. Tuesday, October 15 8:00 AM - 9:30 AM NA MC869 Delayed Emergence After Suboccipital Craniectomy for Chiari I Malformation Natalie Silverton, Mark Harris, M.D., University of Utah, Salt Lake City, UT A healthy 30-year-old woman with Chiari I malformation presented for suboccipital decompression. The conduct of the case was uneventful. After dural closure 10 ml of 0.5% bupivacaine was injected into two small catheters placed in the suboccipital musculature. On emergence the patient's pupils were unreactive and dilated bilaterally. She remained apneic and unresponsive. A nerve stimulator confirmed no residual neuromuscular blockade. Arterial blood gas panel was normal. The patient awoke 66 minutes later with transient bilateral leg numbness. Subsequent CT showed one of the catheters beneath the dura. The catheters were removed and the patient had an otherwise unremarkable course. Tuesday, October 15 8:00 AM - 9:30 AM NA MC870 Airway Management in a Female Patient With Intrauterine Pregnancy of 35 Weeks With Grisel Syndrome: A Case Report Marco Silvestrini, M.D., Victor Rivero, M.D., Hector Torres, M.D., University of Puerto Rico, Yauco, PR Grisel Syndrome is defined as a non-traumatic subluxation of the atlantoaxial joint. Case of a 29-year-old woman with symptomatic atlantoaxial subluxation at 35 weeks of intrauterine pregnancy who was taken to the operation room for cesarean delivery. The patient was found with left hemiparesis dysphagia and shortness of breath of two days of evolution. An awake fiberoptic orotracheal intubation was The presence of a symptomatic atlantoaxial subluxation combined with the anticipated changes of pregnancy makes this an interesting and challenging case. This is the first case reported of an adult pregnant female with Grisel syndrome.

Stroger Jr. Hospital of Cook County, Chicago, IL 28-year-old male presented with multiple GSW including lower extremities abdomen chest right neck zone II and left forehead. Patient underwent an exploration of right neck with ligation of right ICA and IJ for right internal carotid artery pseudoaneurysm and an AVF between RICA and RIJ. This was followed by an emergent decompressive laparotomy for abdominal compartment syndrome and left decompressive craniectomy. Anesthetic management included massive transfusion neuroprotective measures and maintenance of adequate CPP in a patient with HD instability 3L acute blood loss and elevated ICP. Postoperatively patient recovered full neurological function except for partial vision loss. Tuesday, October 15 8:00 AM - 9:30 AM NA MC872 Anesthetic Management of Neonate With Vein of Galen Malformation and Congestive Heart Failure Liza Starecki, M.D., Franco Resta-Flarer, M.D., St. Luke's- Roosevelt Hospital, New York, NY A 1-day-old neonate presented at birth with CHF and was diagnosed with Vein of Galen malformation. He was intubated transferred to our institution and taken emergently for MRI cerebral angiogram and embolization of malformation. Umbilical venous and arterial lines were placed. The CHF was managed with dopamine dobutamine milrinone and nitric oxide perioperatively. Deliberate hypotension necessary for gluing was achieved with sevoflurane. After partial embolization of malformation patient was transferred to neonatal ICU. His CHF improved and he was discharged on digoxin and furosemide twenty days later. His postoperative course was complicated by seizures which were managed with phenobarbital. Tuesday, October 15 8:00 AM - 9:30 AM NA MC873 Delayed Onset Juvenile Stroke Due To Blunt Traumatic Internal Carotid Artery Dissection Nazneen Sudhan, Addenbrookes Hospital UK, Cambridge, United Kingdom, Akash Prashar, M.B. B.S., Norfolk and Norwich University Hospital, Norwich, United Kingdom A juvenile patient presented following road traffic accident with GCS 14 and no focal neurology. Initial head scan was normal. Unstable haemodynamics necessitated emergency laparotomy. Patient was ventilated for next 48 hours for re-exploration surgery. Dense left sided hemiplegia was noted 72 hours post injury when weaning of sedation was attempted. CT angiography confirmed right internal carotid dissection with thrombosis and ischaemic infarct in the middle cerebral artery territory. Patient was managed conservatively and made good neurological recovery without cranial decompression. This rare injury demands a high index of suspicion to enable prompt specialist management to ameliorate severe neurological damage. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM NA MC874 Epidural Anesthesia for Lumbar Decompression Surgery in the High-Risk Geriatric Patient Amar Talati, D.O., Brian Martin, M.D., Stanlies D'Souza, M.D., Baystate Medical Center Tufts University School of Medicine, Springfield, MA A 91-year-old diabetic male with a history of three-vessel coronary artery disease which was medically managed and myocardial infarction one month prior presented for removal of synovial cyst and decompression due to symptomatic lumbar stenosis at L4-L5. In collaboration with the neurosurgeon we planned for epidural anesthesia due to high risk obstructive coronary artery disease. A thoracic epidural catheter was placed at the T10-T11 level and anesthesia was maintained with epidural infusion 0.125% bupivacaine along with low-dose propofol and fentanyl sedation. The catheter was immediately removed upon arrival to recovery. The patient had an uneventful perioperative course. Tuesday, October 15 8:00 AM - 9:30 AM NA MC875 Diaphragmatic Pacing: New and Expanded Indications for an Old Technique. Ahmed Haque, M.D., Christopher Tam, M.D., Shaji Poovathoor, M.D., Deborah Richman, M.B.Ch.B., Dana Telem, M.D., Stony Brook University Hospital, Stony Brook, NY Diaphragmatic pacing had been used successfully in the past to wean ventilator dependent patients with quadriplegic spinal cord injuries. Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder. Respiratory and bulbar dysfunction are the leading causes of death and respiratory support is uniformly needed in the later stages of the disease. Initially non-invasive Bi-Pap is helpful but tracheostomy and mechanical ventilation follow - not always acceptable to patients. We present the case of a 48-year-old man with ALS presenting for diaphragmatic pacing. Our anesthetic management successful wean and discharge home of this patient are discussed. Tuesday, October 15 8:00 AM - 9:30 AM NA MC876 Acute STEMI Presenting During an Awake Craniotomy for Removal of Brain Tumor Jacob Tiegs, M.D., Daniel Betterly, M.D., Mitch Lee, M.D., New York University, New York, NY 51-year-old male with HTN CAD and brain tumor presenting for awake craniotomy for tumor removal. Patient initially intubated and headpins placed. Next patient extubated and given local infiltration over pins while sedated with remifentanyl and dexmedetomidine. Suddenly the patient complained of chest pain. ST elevations noted on monitor. The surgeons made aware no aspirin given. Surgery concluded and skull closed. Cardiology made aware and PACU 12 lead EKG showed STEMI in LAD distribution. Cath showed occlusion of LAD. Occlusion suctioned and balloon angioplasty performed. No heparin or stents used due to recent brain surgery. Patient transferred to ICU. Tuesday, October 15 8:00 AM - 9:30 AM NA MC877 Swing and a Miss in a Patient With Lou Gehrig's Disease Matthew Torre, D.O., Scott Miller, M.D., Wake Forest University, Winston-Salem, NC We discuss the first two cases performed at our institution for placement of the newly approved Diaphragm Pacing System (DPS) in patients with Amyotrophic Lateral Sclerosis (ALS). Important Copyright © 2013 American Society of Anesthesiologists anesthetic implications and airway management are discussed including the avoidance of paralytics during the case. Our first patient was induced with remifentanil and propofol which caused rigidity likely due to remifentanil. Rescue intubation was achieved with a lightwand. Our second case underwent awake fiber-optic intubation due to severe respiratory compromise and poor airway predictors without incident. Both patients were successfully extubated in the O.R without adverse outcomes postoperatively. Tuesday, October 15 8:00 AM - 9:30 AM NA MC878 Acute Hypotensive Transfusion Reaction With Concomitant Use of Angiotensin-Converting Enzyme Inhibitors in a Neurosurgery Case Catherine Vu, M.D., Scott Eber, M.D., Jackson Memorial Hospital, Miami, FL The pathophysiology of AHTR involves bradykinin a vasoactive peptide that binds endothelium receptors and causes hypotension. ACE inhibitors prevent bradykinin breakdown. Thus patients who take ACE inhibitors have higher levels of bradykinin and are prone to AHTR. Our case involves a 59-year-old female who took ACE inhibitors on the day of surgery for intracranial aneurysm repair. Her SBP dropped from 130mmHg to 60mmHg within minutes of starting blood transfusion. The transfusion was stopped and the patient's SBP increased back to 130mmHg range. The patient later received 1 unit of leukocytereduced PRBC prepared by the blood bank without changes in hemodynamics Tuesday, October 15 8:00 AM - 9:30 AM NA MC879 A Case Report: Anesthetic Management of A Patient With Kennedy's Syndrome Undergoing Peripheral Re-vasculization Jiang Wu, M.D., Lee Wallace, M.D., Shiva Sale, M.D., Cleveland Clinic, Beachwood, OH Patients with Kennedy's disease(KD) might be at risk of laryngospasm aspiration and postoperative respiratory failure. We describe the anesthetic management of a patient with KD with past anesthetic history significant for postoperative larygospasm and acute respiratory failure requiring re-intubation presenting for peripheral revascularization. Supraglottic airway was used and anesthetic was devoid of neuromuscular blockade. The perioperative course was uneventful; there was no exacerbation of neurologic signs or symptoms. We suggest that a patient with Kennedy's disease may be successfully managed by supraglottic airway with assisted ventilation for peripheral vascular procedure if there are no contraindications.

A spider bite led to infection multiple surgical debridements and a rotational flap to cover the first web space of his hand. He developed scarring of this area with severe chronic pain that had lead the patient to seek amputation of his hand. In our pain medicine clinic he was given a neuroma block with 0.25% bupivacaine and a normal saline injection into a trigger point in his flexor digitorum superficialis radial head with complete resolution of his pain. Tuesday, October 15 8:00 AM - 9:30 AM PN MC883 Percutaneous Interferential Current Therapy Relieves Abdominal Pain Phung Pham, M.D., Konstantinos Sarantopoulos, M.D., Ashish Udeshi, M.D., Jackson Memorial Hospital, Miami, FL, Maria Forrest, M.D., Harvard, Boston, MA Interferential Current Therapy (ICT) uses alternating criss-crossing 3000-5000 Hz of electrical current. When applied percutaneously over areas of pain it can produce analgesia and stimulate muscle function. While ICT has been used extensively for the relief of musculoskeletal pain its potential against visceral and neuropathic pain remains unclear. We report two cases of successful application of percutaneous ICT for the management of abdominal pain from diabetic gastroparesis and chronic pancreatitis. ICT has a potential as a simple and possibly cost-effective therapy for abdominal pain. In addition to analgesia ICT may promote GI motility by stimulation of GI smooth muscles. Tuesday, October 15 8:00 AM - 9:30 AM PN MC885 Gasserian Ganglion Pulsed Radiofrequency Acupuncture and Biofeedback for Severe Trigeminal Neuralgia Abed Rahman, M.D., David Wahba, M.D., Cook County Health System, Chicago, IL, Raed Rahman, D.O., Cancer Treatment Centers of America, Zion, IL 32-year-old male with multiple sclerosis presenting with several year history of severe unilateral trigeminal neuralgia not responsive to local anesthetic and steroid injections currently maximal doses of medications. Patient progressively becoming depressed lost job due to severity of pain now dependant on opiods. Started with psychological biofeedback with pain psychologist for 1 month acupuncture weekly.

NSF has few treatment options relying on evidence comprised of case series. This case highlights a 44-year-old female on dialysis who received gadolinium and developed NSF refractory to kidney transplant imatinib pentoxyfylline and plasmapheresis who receives maximal benefit from total body intralesional injections with local anesthetic and corticosteroids. Discussion will include diagnostic criteria of NSF literature review of treatment options and pathogenesis as a basis for response to intralesional injections with local anesthetic with glucocorticoids. Tuesday, October 15 8:00 AM - 9:30 AM PN MC887 Management of Opiod-Induced Hyperalgesia Following Brachial Plexus Injury Nicholas Riegels, Kaiser Oakland, Oakland, CA A 20-year-old man sustained lung contusions pneumothorax subdural hematoma mandibular fracture occipital condylar fracture and right brachial plexus injury in a high-speed MVA. He responded favorably to stabilization of his injuries but experienced severe burning tingling right arm pain with bouts of generalized myoclonus; pain service consultation ensued. His analgesic regimen included gabapentin nortriptyline hydromorphone and fentanyl amounting to 2280 mg of oral morphine equivalents daily. Opiate rotation to methadone was undertaken out of suspicion for opiod-induced hyperalgesia. Hydromorphone was weaned over several days followed by weaning of fentanyl and then methadone. The patient's analgesia improved markedly; myoclonus resolved. Tuesday, October 15 8:00 AM - 9:30 AM PN MC888 Management of an Opioid Tolerant Patient After Extensive Spine Surgery Najmeh Sadoughi, M.D., Margaret Miller, M.D., University of Southern California, Los Angeles, CA A 54-year-old female with history bipolar fibromylagia dystonia and chronic pain admitted for repair of her scoliosis. She was on chronic pain medications at home equivalent to 260 mg Intravenous morphine daily and was scheduled for L1-Pelvis Posterior spinal Fusion and L5-S1 anterior Lumbar Interbody Fusion. Pain control immediately post operatively was achieved with Fentanyl Ketamine and Versed infusion without intubation. On postoperaion Day 4 patient's home oral pain medication regimen was converted to transdermal fentanyl patch and supplemented with oxycodone for breakthrough pain. Fentanyl patch was then slowly titrated down over hospital stay as tolerated by patient. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM PN MC889 Lagophthalmos Following Selective V2 Maxillary Nerve Block Amit Shah, M.D., Yale University School of Medicine, New Haven, CT, Srdjan Nedeljkovic, M.D., Brigham and Women's Hospital/Harvard Medical School, Boston, MA There are a number of complications associated with maxillary nerve blockade. Fluoroscopic guidance can reduce procedure time and complications from needle misplacement. We report a case of lagophthalmos that has not been described in literature. Following a successful maxillary block from an infrazygomatic approach the patient reported an inability to close her ipsilateral eye. Symptoms resolved in 40 minutes. Conclusion: The zygomatic branches of the facial nerve are relatively superficial and in close proximity to the cutaneous point of entry to maxillary nerve blockade. The spread of subcutaneous local anesthetic infiltration can involve these branches resulting in transient ipsilateral lagophthalmos. Tuesday, October 15 8:00 AM - 9:30 AM PN MC890 Damaged Radiofrequency Cannula: Effects on a Patient Undergoing Thermal Radiofrequency Ablation of Cervical Medial Branch Nerve and Examination of the Damaged Radiofrequency Cannula Bharat Sharma, M.S., Satvik Munshi, M.D., Louisiana State University School of Medicine, New Orleans, LA, Sanjay Sharma, M.D., VA Medical Center, New Orleans, LA, James Cronin, Ph.D.; Tulane University, New Orleans, LA A 62-year-old man felt discomfort even after injection of local anesthetic prior to thermal radiofrequency lesioning of the cervical medial branch. He did not feel any pain after the cannula was replaced with a new cannula in exactly the same location. Macro photography showed some damage to the insulation of the 22G cannula possibly during the procedure. Coagulation was observed when a simulated lesion was produced in albumin at 80°C. We plan to check for current leaks along the length of the needle with a multimeter and perform a light microscopic and surface electron microscopic examination. Tuesday, October 15 8:00 AM - 9:30 AM PN MC891 Accidental Massive Morphine and Bupivacaine Dose Delivered Subcutaneously During Refill of Implantable Drug Delivery Device for Intrathecal Analgesia: A Case Report Paramvir Singh, M.D., Gunar Subieta, M.D., Pratiksha Trivedi, M.D., Taruna Penmetcha, M.D., Maria Torres, M.D., John H Stroger Hospital of Cook County, Chicago, IL 47-year-old female FBSS had Intrathecal pump placed for analgesia. Dose- Morphine 3mg/day Bupivacaine 4mg/day. During one visit for refill of the pump with 240mg Morphine and 320 mg Bupivacaine by the fellow the needle apparently became dislodged and the drug was injected into a subcutaneous pocket. The patient complained of being sleepy and nauseated. The misdirected injection was quickly suspected. The pump reservoir was accessed and found to be empty. Immediately the patient was given 0.04 mg of naloxone intravenously begun on a continuous infusion 0.1mg/hr. The patient was monitored overnight. No sequelae of LA toxicity noticed.

Physical examination revealed symmetrical peripheral pulses; cervical and upper back trigger points; and a positive bilateral Spurling's test. Cervico-thoracic MRI revealed foraminal stenoses in both regions; and thoracic facet joint hypertrophy. Trigger point injections topiramate and meloxicam trials provided variable limited relief. Tension headaches and decreased right hand strength began around treatment day 360. Peripheral pulses were symmetrical until asymmetrical pulses were found on day 678. Angiography revealed right subclavian artery occlusion with subclavian steal. Tuesday, October 15 8:00 AM - 9:30 AM PN MC893 Capacity Competency and Consent in a Severely Traumatic Injury Carlyle Hamsher, M.D., Mount Sinai Medical Center, NewYork, NY, Christopher Spevak, M.D., Georgetown University School of Medicine, Washington, DC A 22-year-old service member presents after sustaining a dismounted complex blast injury with multiple limb amputations and severe neuropathic pain in a remaining extremity due to sciatic nerve avulsion. The pain was treated with a multimodal and multidisciplinary approach including high dose oral and IV opioids membrane stabilizers nonsteroidal anti-inflammatories anti-depressants ketamine infusion regional anesthesia physical therapy TENS acupuncture and cognitive behavioral therapy. The team considered spinal cord stimulation. The issue facing the team was how to obtain consent for an elective surgical procedure in a patient with severe pain receiving a combination of opioids and other medications affecting neurocognition. Tuesday, October 15 8:00 AM - 9:30 AM PN MC894 Low Back Pain From Bertolotti's Syndrome Successfully Treated With CT-Guided Dehydrated Amnion and Chorion Membrane (AmnioFix) Injection Charles Stehman, M.D., Jeremy Hackworth, M.D., Naval Medical Center San Diego, San Diego, CA Human amnionic membrane has potent regenerative and anti-inflammatory properties. We present a case where injectable dehydrated amnionic and chorionic membrane was injected to a patient with low back pain presumably from the psuedoarticulation present in Bertolotti's syndrome which resulted in near complete resolution of back pain at the injection area. After temporarily responding to a local and steroid injection once the pain returned the patient was injected with steroid on the left and amnionic membrane on the right. After 3 months the patient had near complete resolution of the pain on the right with no resolution on the left.

Past medical history was significant for lumbar radiculopathy and diverticulosis and she had no significant surgical or social history. She was prescribed voltaren gabapentin and pregabalin none provided relief. She concurrently received three thoracic epidural injections which relieved her symptoms for only a week each time. At that point pulsed radiofrequency ablation of the left T8 T9 and T10 dorsal root ganglion was performed. She experienced significant improvement and on 6-month follow-up she reported sustained 60-70% pain relief. Furthermore on one-year follow-up she noted 50% continued relief. Tuesday, October 15 8:00 AM - 9:30 AM PN MC896 Spinal Cord Stimulation for Electrical Storm Refractory to Conventional Medical Treatment Hong Vo, M.D., David Walega, M.D., Northwestern University Feinberg School of Medicine, Chicago, IL Our patient is a 35-year-old male with familial dilated cardiomyopathy s/p biventricular internal cardiac defibrillator (ICD) placement. Despite being medically treated with sotalol and amiodarone he presented to the ER with an electrical storm after his ICD delivered 13 shocks. He was admitted to the cardiac intensive care unit (CICU) treated with amiodarone suppressive therapy and discharged home under stable condition. The following day he was readmitted to the CICU after his ICD fired multiple shocks. In this case report we describe the potential benefit of spinal cord stimulation in treating intractable ventricular tachyarrhythmias. Tuesday, October 15 8:00 AM - 9:30 AM PN MC897 Detoxification as a Treatment for Opioid-Induced Hyperalgesia Jenna Walters, M.D., Kurt Dittrich, M.D., Vanderbilt University Medical Center, Nashville, TN 57-year-old female with systemic lupus erythematosus and sarcoidosis presented with complaints of chronic uncontrolled fibromyalgia pain. Her treatment regimen included Morphine SR 100mg twice daily and Ibuprofen which had slowly escalated over four years. She endorsed symptoms of depression despite treatment with Risperidone and denied suicidal ideation. Due to concern for opioid-induced hyperalgesia she completed seven days of hospital based inpatient detoxification utilizing a protocol of buprenorphine clonidine and psychological counseling. She was discharged completely off Morphine but continued on Tramadol 50mg every four hours and Risperidone. She remains opioid free and feels she has her life back. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM PN MC898 Ultrasound Guided Intrathecal Pump Refill Xueyuan Wang, M.D., Hung-Lun Hsia, M.D., Lance Roy, M.D., Billy Huh, M.D., Ph.D., Duke University Medical Center, Durham, NC Intrathecal pump refills can be challenging in patients with difficult anatomy or pump positioning. Catastrophic overdoses can occur if pump medication is inadvertently injected outside the reservoir. We describe using Doppler ultrasound for difficult pump refills whereby the refill port is located using direct ultrasound guidance and the medication flow path is directly visualized using Doppler technology. This method allows for immediate confirmation that medication is being delivered into the reservoir and not extravasating into surrounding tissue. In addition to visualization of flow use of ultrasound may be preferable to fluoroscopy due to lack of radiation and flexibility in positioning. Tuesday, October 15 8:00 AM - 9:30 AM PN MC899 Flipped Intrathecal Pump Identified Using Ultrasound John Young, M.D., James Stephens, D.O., Robert Rowlett, M.D., Tilak Raj, M.D., Randall Henthorn, M.D., University of Oklahoma HSC, Oklahoma City, OK A 29-year-old obese female with severe CRPS was in need of a refill of her intrathecal baclofen pump. Her pump was hyper-mobile and frequently flipped in the subcutaneous pocket. X-rays were difficult to obtain due to her condition and were unreliable in identifying the current pump orientation because the pump would flip while moving off the x-ray table. Ultrasound was used at bedside to identify not only the location of the pump but also it's orientation at the time of refill. Ultrasound is a simple safe and effective way to identify pump orientation. Tuesday, October 15 8:00 AM - 9:30 AM RA MC900 The Utility of Peripheral Nerve Block for Positioning of Multiple Trauma Victim in Adjunct to Conduction Anesthesia Elizabeth Rivas, M.D., Hana Teissler, M.D., Texas Tech University Health Sciences Center at El Paso, El Paso, TX 75-year-old male sustained automobile vs. pedestrian accident with multiple open fractures in bilateral lower extremities. The patient medical history was significant for CAD MI CHF Af HTN AICD placement pulmonary HTN and OSA. Echo showed global systolic dysfunction with LVEF 20%. Interdisciplinary communication with the orthopedic surgeons was necessary to provide the safest and most appropriate anesthetic management. Due to his co-morbidities the decision for regional anesthesia was made. PNB was conducted to minimize the positional pain. Then combined spinal/epidural anesthesia was performed. After the uneventful surgery the patient was taken to PACU in stable condition with minimal pain. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM RA MC901 Continuous Spinal Anesthesia for Hip Replacement in an Elderly Patient With a Large Anterior Mediastinal Mass: Case Report Victor Rivero, Osmar Creagh, M.D., Daniel Fernandez, M.D., Cesar Hernandez, M.D., University of Puerto Rico Medical Sciences Campus, San Juan, PR Continuous spinal anesthesia (CSA) allows for better control of adverse effects caused by sympathetic nerve blockade. We report a 91-year-old female with a left intertrochanteric fracture and a large thyroid mass causing displacement of the trachea and great vessels. We conducted a detailed investigation of the different techniques used in such circumstances and the consequences each may have. CSA is an anesthetic alternative to consider on elderly patients with an anterior mediastinal mass undergoing hip fracture surgery. Tuesday, October 15 8:00 AM - 9:30 AM RA MC902 Delayed Recognition of Inadvertent Intrathecal Catheterization: The Next Step? Pragati Rohatgi, M.D., Keun Chung, M.D., Yale University School of Medicine, New Haven, CT A 71-year-old female undergoing bilateral knee arthroplasty had L2-L3 epidural catheter placed for postoperative analgesia. Test dose with lidocaine/epinephrine was negative. Upon completion of the operation (general anesthesia) 5cc 0.125% bupivacaine was given epidurally after negative aspiration (CSF). Patient awoke complaining of knee pain. Additional 5cc 0.125% bupivacaine was injected after negative aspiration. In PACU she was awake but hypotensive and hypoxemic and sensory blockade to T4. BP responded to IV ephedrine and phenylephrine. CSF was aspirated from epidural catheter. For the next 24 hours this catheter was employed for continuous spinal analgesia with pain scores 2-4/10 without complications. Tuesday, October 15 8:00 AM - 9:30 AM RA MC903 Warming Blanket Induced Increased Transcutaneous Fentanyl Absorption as Cause of Postoperative Somnolence Martin Samborski, M.D., Rose Campise Luther, M.D., Medical College of Wisconsin, Wauwatosa, WI A patient presents for open right cytoreductive nephrectomy renal cell carcinoma. Preoperative medication included a 50mcg Fentanyl Patch and Oxycodone. He had a thoracic epidural placed bolused with 1mg of dilaudid and bupivacaine 0.25% with epi. Additionally he received 300mcg of Fentanyl over 6h. The patient remained somnolent 12h postoperatively with respiratory rates as low as 6 even after changing the epidural infusion to a non narcotic solution 5h postoperatively and the fentanyl patch removed. We hypothesized that the patient received a transcutaneous opoid overdose by placing the patch under a warming blanket and increasing absorption. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM RA MC904 Aortic Stenosis and Continual Spinal Anesthesia Maricela Sanchez, Anthony Brown, M.B.Ch.B., Danielle Ludwin, M.D., Columbia University Medical Center, New York, NY A patient with severe aortic stensosis presented with a hip fracture and is scheduled for urgent hip hemiarthroplasty. The chief anesthetic goal in the setting of aortic stenosis is the avoidance of sudden reduction in systemic vascular resistance. Neuraxial anesthesia is traditionally considered to be a contraindicated due to associated hypotension. However the use of a continuous spinal anesthetic is associated with a decreased risk of hypotension compared to a single shot spinal anesthetic and yet provides a more reliable and dense sensory and motor block than an epidural anesthetic. Tuesday, October 15 8:00 AM - 9:30 AM RA MC905 Tracking Success: In-Plane Approach to Continuous Popliteal Catheter Placement Krystal Scherrer, M.D., Atilla Kerner, M.D., Saint Louis University, St Louis, MO 58-year-old M without significant PMH who presented s/p trauma with an open tibia fracture. A continuous popliteal nerve catheter was placed using an in-plane technique. After positioning the probe was rotated to view the nerve in the long axis. A block needle was positioned via an in-plane approach to the posterior LAX in a caudal to cephalad direction. The catheter was visualized as it was threaded parallel to the nerve. Placement was confirmed using motor twitch. Analgesia was achieved via a ON-Q C-bloc pump. The patient had pain relief for 9 days without migration or kinking of the catheter. Tuesday, October 15 8:00 AM - 9:30 AM RA MC906 Shoulder Surgery Under Regional Anesthesia in a Patient With Partial Lung Resection Eric Schwenk, M.D., Jaime Baratta, M.D., Kishor Gandhi, M.D., Jefferson Medical College, Philadelphia, PA An 89-year-old female with history of heavy smoking and left lung lobectomy presented for right shoulder arthroplasty. She insisted on regional anesthesia. A multimodal approach including interscalene block acetaminophen ketorolac and opioids was taken. Surgery proceeded uneventfully and postoperative analgesia was excellent. Interscalene block impairs ipsilateral lung function and lung disease is a relative contraindication. We present a successful outcome in a patient with pre-existing reduced left lung function who then received a continuous interscalene block causing right-sided hemidiaphragmatic paresis. To accommodate the wishes of the patient's family a multimodal approach that avoided general anesthesia and minimized opioids was emphasized. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM RA MC907 Prolonged Spinal Anesthesia (>10 Hours) Following CSE Placement for Emergent Ankle Fracture Repair and It's Not What You Think Brian Seacat, M.D., Tilak Raj, M.D., Praveen Kalra, M.D., University of Oklahoma Health Sciences Center, Oklahoma City, OK We report a 65-year-old female with an interesting and complicated past history which included a mediastinal mass and cardiac arrest on induction presenting to us with an open ankle fracture following an accident requiring urgent repair. CSE was performed with adequate surgical anesthesia. Five hours following 1.6 mL 0.75% bupivacaine with 20 mcg fentanyl no neurological function had returned. Urgent MRI showed spinal ischemia above the block level. Patient was transferred to the trauma ICU and phenylephrine infusion was initiated to maintain MAP >75 mmHg. Neurological function returned 10hours post-puncture with an uncomplicated further hospital course. Tuesday, October 15 8:00 AM - 9:30 AM RA MC908 Use of Diphenhydramine 0.5% as a Local Anesthetic for a Pacemaker Placement in a Patient With Severe Aortic Stenosis Mobitz Type II AV Block With RBBB and True Allergy to Amide and Ester Local Anesthetics Tanvi Shah, M.D., Ph.D., Ahmad Elsharydah, M.D., UT Southwestern Medical Center, Dallas, TX An 85-year-old male (98 kg 183 cm) was admitted to our institution for a work-up of syncope. He was found to have a severe aortic stenosis with a normal EF and Mobitz type II atrio-ventricular block with RBBB. His other medical problems include HTN stroke and trigeminal neurolgia. He has a true allergy to local anesthetics (amides and esters) according to his medical chart. A single chamber pacemaker was implanted utilizing Diphenhydramine 0.5% as local anesthetic and MAC. Patient tolerated procedure very well. Tuesday, October 15 8:00 AM - 9:30 AM RA MC909 Don't Place That Regional Block: I'm Monitoring for Compartment Syndrome! Mourad Shehebar, M.D., Meg Rosenblatt, M.D., Icahn School of Medicine Mount Sinai, New York, NY Compartment syndrome (CS) is rare and devastating. CS is caused by trauma with subsequent increased tissue pressure resulting in ischemia muscle necrosis and increased pain. Regional blocks have been eschewed by surgeons as possibly masking symptoms of CS which could delay diagnosis and treatment. A 31-year-old female presented for a tibia ORIF. Single shot popliteal and femoral blocks with 0.25% bupivacaine were performed preoperatively with subsequent LMA placement under GA. Vigilance understanding the signs and symptoms of CS ongoing patient assessment and having a high index of suspicion permitted the use of these techniques to provide optimal analgesia. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM RA MC910 68-Year-Old 51 kg Female With Bilateral Transversus Abdominus Plane (TAP) Catheters Presented With Bilateral Quadricep Muscle Weakness T4 Sensory Level and Shortness of Breath on POD#2 Meredith Shepherd, M.D., Jonathan House, M.D., Kristen Spisak, M.D., Indiana University, Indianapolis, IN 68-year-old 51kg ASA3 Female with bilateral Transversus Abdominus Plane (TAP) Catheters placed for post operative pain control for a cystectomy was found to have bilateral quadricep weakness T4 sensory level and shortness of breath on POD#2. Pt reported 0/10 pain at this time with TAP Catheters infusing 0.2% Ropivicaine at 8ml/hr on each side. Pt's TAP catheters were discontinued at this time. Five hours after discontinuation normal sensation returned and shortness of breath resolved. Ten hours after discontinuation normal motor function of her lower extremities also returned. Tuesday, October 15 8:00 AM - 9:30 AM RA MC911 Subcostal TAP Block With the Lateral Classic TAP Block to Control Pain in a Patient With a Large Complex Adnexal Mass Undergoing Surgical Debulking Kimberly Simms, M.D., Clara Espi, M.D., University of Southern California, Los Angeles, CA A 66-year-old female with worsening abdominal pain was found to have a 17-cm complex adnexal mass and was scheduled for a total abdominal hysterectomy, bilateral salpingo-oophorectomy and surgical debulking. The patient refused epidural analgesia, but agreed to a transversus abdominis plane (TAP) block. Bilateral subcostal TAP blocks below the rectus abdominus muscle, and bilateral lateral classic TAP blocks were performed, both with ultrasound. This dual TAP block eliminated the need for analgesics during incision of the abdominal wall and minimized subsequent analgesic requirements. For cases with extensive vertical abdominal incisions, the bilateral dual TAP block should be considered. Tuesday, October 15 8:00 AM - 9:30 AM RA MC912 A Laminar Approach to the Paravertebral Block in a Patient With Pleural Effusion James Slotto, M.D., Justin Heil, M.D., Naval Medical Center San Diego, San Diego, CA The thoracic paravertebral block is a standard pain management tool for breast surgery but carries the notable risk of pneumothorax. The risk of a small pneumothorax is generally outweighed by the pain control benefits. We present a patient undergoing palliative mastectomy for malignant breast cancer complicated by chronic pleural effusion requiring a contralateral chest tube. To avoid a bilateral pneumothorax a traditional paravertebral block was contraindicated. A laminar approach to the Paravertebral block was used; whereby the needle is kept external to the intercostals space. This block provided excellent pain control while reducing the risks of an otherwise difficult block. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM RA MC913 Anesthetic Management for Hemiarthroplasty in a Pulmonary Cripple With Lumbar Spine Hemangioma Stephen Vose, M.D., M.S., Jozsef Endredi, M.D., University of Florida College of Medicine North Florida/South Georgia VA Medical Center, Gainesville, FL 66-year-old M with PMH of severe COPD is admitted with right femoral neck fracture and RLL pneumonia. Surgical intervention is postponed in favor of medical optimization. By hospital day (HD) three the patient requires ventilatory support and MICU admission. It is HD nine before his medical team clears him for surgery. Anesthesia Pre-Op Assessment discovers a previously unrecognized history of L3 Hemangioma. After further workup and consultation was performed the patient was able to safely undergo epidural placement under fluoroscopic guidance. The operation proceeded successfully under epidural anesthesia thus avoiding general anesthesia in this high risk patient. Tuesday, October 15 8:00 AM - 9:30 AM RA MC914 Arthroscopic Rotator Cuff Repair in a Patient With Eisenmenger Physiology: Ambulatory Interscalene Catheter Tariq Malik, Nihir Waghela, M.D., Anthony Tantoco, M.D., University of Chicago Hospitals, Chicago, IL A 58-year-old woman with pulmonary HTN and ASD on remodulin infusion needed rotator cuff repair. Regional anesthesia with a superficial cervical block was planned for the procedure. An Interscalene catheter was placed with ultrasound guidance. Lidocaine 2% was administered at 2 ml every 15 min up to 6 ml over 45 min to block C5 and C6. The patient tolerated 3 hr of surgery with no other sedation. After the surgery the catheter was infused with 0.125% bupivacaine 4 ml/hr. She was discharged with the catheter which provided excellent analgesia. The catheter was removed on POD 3. Tuesday, October 15 8:00 AM - 9:30 AM RA MC915 Management of Thoracic Epidural in the Setting of Complete Anticoagulation During Emergent Cardiac Catheterization for Intraoperative RCA Occlusion Christian Walker, M.D., Sujatha Bhandary, M.D., The Ohio State University, Columbus, OH A 65-year-old male with a history of CAD with MI s/p CABG hyperlipidemia DMII PVD and laryngeal cancer presented for resection of right upper lobe mass by thoracotomy. A pre-operative thoracic epidural was placed for pain control. The patient developed intra-operative MI needing pacer placement and bleeding necessitating re-exploration before proceeding to cardiac catheterization. He required anti-platelet therapy with aspirin loading dose clopidogrel and full anticoagulation with bivalirudin infusion for placement of three bare metal stents for complete RCA occlusion. The thoracic epidural was removed on post-operative day 7 and the patient was discharged home without neurological complications. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM RA MC916 Diagnostic and Therapeutic Occipital Nerve Blocks for Reported Trauma Induced Occipital Neuralgia Jeremie Walker, M.D., Stephen Howell, WVU, Morgantown, WV The patient described in this case report developed post-traumatic headaches following a motor vehicle collision with head injuries. After non-invasive approaches to the management of his occipital neuralgia failed (4 week hospital course) bilateral greater occipital nerve blocks conferred symptom relief in a matter of hours. This case report highlights an interesting presentation of post-traumatic occipital neuralgia and underscores the utility of occipital nerve block as a therapeutic and potential diagnostic modality. Tuesday, October 15 8:00 AM - 9:30 AM RA MC917 Regional Anesthetic Management of a Turner's Syndrome Patient for a Non-Cardiac Procedure Mi Wang, Rakhi Pal, Kenneth Cummings, Cleveland Clinic Foundation, Cleveland, OH A 39-year-old woman with Turner's syndrome was scheduled to undergo orthpedic surgery. She had compromised heart function with coarctation of the aorta and multiple other comorbidities. She had a short stature with a short webbed neck and severe scoliosis. We chose regional anesthesia supplemented with intravenous sedation. Due to her short webbed neck infraclavicular block was considered anatomically more favorable than supraclavicular block. A single injection of local anesthetic was administered under ultrasound and sedation was achieved with propofol infusion. Her blood pressure was within normal limits no arrthymia occurred and anesthesia was uneventful with a satisfying outcome. Tuesday, October 15 8:00 AM - 9:30 AM RA MC918 Lower Extremity Peripheral Nerve Block in a Patient With Charcot-Marie-Tooth Disease Michael Wassef, M.D., Ali Shariat, M.D., St. Luke's-Roosevelt Hospital Center, New York, NY An 18-year-old man suffering from Charcot-Marie-Tooth disease was scheduled for right foot osteotomy and tendon transfer. The patient refused GA due to history of severe post-operative nausea and vomiting. A right-sided popliteal block was performed under triple monitoring using ultrasound guidance peripheral nerve stimulation and in-line pressure manometry (to assure an injection pressure below 15 psi). Ropivacaine 0.5% 20 mL was injected under ultrasound visualization. Sensory and motor block ensued within 10 minutes and surgery proceeded uneventfully. The patient had full recovery of motor function 6-7 hours after the block was performed with pain relief lasting 28 hours. Tuesday, October 15 8:00 AM - 9:30 AM RA MC919 Subcostal Transversus Abdominis Plane Block to Facilitate Laparoscopic Cholecystectomy Without Neuromuscular Blockade in a Patient With Myasthenia Gravis Douglas Wetmore, M.D., Lucas Bejar, M.D., Meg Rosenblatt, M.D., Icahn School of Medicine at Mount Sinai, New York, NY A 68-year-old female with myasthenia gravis on chronic pyridostigmine requiring recent plasmapheresis presented for laparoscopic cholecystectomy. Pyridostigmine was continued until the operation. Our goal Copyright © 2013 American Society of Anesthesiologists was to avoid neuromuscular blockade subsequent reversal and potential cholinergic crisis. Anesthesia was induced with propofol and remifentanil. A subcostal transversus abdominis plane block with 30mg of 0.25% bupivacaine was performed using ultrasound-guided block technique for perioperative analgesia. Anesthesia was maintained with remifentanil titrated to effect and sevoflurane at >1 MAC. TOF was .65 after induction and 1 prior to extubation. Only 50mcg of fentanyl in addition were required for analgesia during the perioperative period. Tuesday, October 15 8:00 AM - 9:30 AM RA MC920 Bilateral TAP Blocks in Early Stage of Postoperative Abdominal Wall CRPS Judd Whiting, M.D., Kerry Hollenbeck, M.D., Naval Medical Center San Diego, San Diego, CA 32-year-old male underwent midline laparotomy for left renal vein transposition. Postoperative day two he endorsed 10/10 pain of the abdominal wall diagnostic for CRPS type 1. He couldn't tolerate positioning for epidural placement. Bilateral ultrasound-guided TAP blocks were performed using classic and subcostal needle insertion points resulting in complete pain relief. He then tolerated a thoracic epidural placement. Return of allodynic pain 2 days later was treated with a ketamine infusion and a hydromorphone PCA. Epidural was continued until postoperative day eight. The patient was discharged the same day with pain controlled on only oral opioids. Tuesday, October 15 8:00 AM - 9:30 AM RA MC921 Management of Acute on Chronic Pain in the Trauma Patient Lara Zador, M.D., Donna Thomas, M.D., Yale New Haven Hospital, New Haven, CT Pt is a 24-year-old male construction worker with chronic pain presents with radius fracture after falling 25-feet at work.

Her past medical history was significant for a remote history of seizure attributable to a drug reaction and currently treatment with valproate for mood stabilization discontinued 7 days prior to ECT. She had successful ECT treatments 7 months previously. After anesthetic induction with etomidate and succinylcholine a threshold delivered stimulus produced a prolonged seizure of approximately 15 minutes which was treated unsuccessfully with midazolam and propofol followed by dilantin which terminated the seizure. The patient recovered uneventfully with post-ictal signs. The background workup treatment and recovery are discussed. Tuesday, October 15 8:00 AM - 9:30 AM CC MC924 Palliative Splenectomy in a Patient With Myelofibrosis and Severe Symptomatic Anemia Secondary to Hemolysis and Splenic Sequestration Jessica Stevens, M.D., Susan Martinelli, M.D., University of North Carolina, Chapel Hill, NC Myelofibrosis is a chronic myeloproliferative disorder in which the accumulation of myeloid progenitors leads to pathologic enlargement of the spleen resulting in anemia secondary to hemolysis and splenic sequestration. Splenectomy has been shown to be an effective palliative procedure with acceptable morbidity in select patients with myelofibrosis. We present a case of a 66-year-old male with severe symptomatic anemia from myelofibrosis scheduled for palliative splenectomy. Due to the patient's severe transfusion dependent anemia and multiple red cell antibodies this case required significant perioperative communication and preparation with the blood bank and the surgical team . Tuesday, October 15 8:00 AM - 9:30 AM CC MC925 Ethical Dilemmas In Managing A Brain Stem Dead Pregnant Patient Nazneen Sudhan, Sridhar Nallapareddy, M.D., F.R.C.A, Addenbrookes Hospital, Cambridge, UK A preterm parturient with history of severe headaches for one month presented with seizures. An MRI head showed a frontal mass lesion with enhancement. After 12 hours of stable neurology patient developed dilated fixed pupils needing emergency craniotomy and debulking of tumor histologically confirmed as anaplastic oligodendrglioma. There was no improvement in the neurological status despite neurosurgical intervention and patient was pronounced brainstem dead. Great ethical issues were encountered in context of alive non-viable fetus. Patient's family chose to not continue the somatic support prolongation to save the life of fetus however allowed to procure the maternal organs for transplantation. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM CC MC926 Anesthetic Management of Ruptured Pulmonary Artery Rasmussen Aneurysm and Massive Hemoptysis Madiha Syed, M.B. B.S., Jill Irby, M.D., University of Arkansas for Medical Sciences, Little Rock, AR Massive hemoptysis secondary to pulmonary artery aneurysm rupture is a rare phenomenon presenting unique challenges in airway management and stabilization of oxygenation ventilation and blood pressure. We present a case of a 35-year-old female with necrotizing cavitatory tuberculosis complicated by ruptured pulmonary artery Rasmussen aneurysm and massive hemoptysis. Patient required emergent intubation resuscitation and hemodynamic stabilization prior to undergoing emergent embolization by interventional radiology. Tuesday, October 15 8:00 AM - 9:30 AM CC MC927 Abdominal Compartment Syndrome Post Splenic Artery Embolisation Ngano Takawira, M.B.Ch.B., Pablo Moujan, M.D., John Zaki, M.D., Elizabeth Rivas, M.D., Texas Tech El Paso, El Paso, TX A 64-year-old male presented with an acute abdomen .A CT scan revealed a large pancreatic mass with erosion into the splenic artery and splenic artery extravasation.A diagnosis of a metastatic pancreatic malignancy was made and Interventional Radiology embolized the splenic artery but the patient continued to deteriorate in the ICU the patient's bladder pressures were grossly elevated and a diagnosis of abdominal compartment syndrome was made.A decompressive laparotomy was performed and although the abdominal pressure came down it did not normalize.The patient developed multiorgan failure and his family decided to withdraw care and he subsequently expired. Tuesday, October 15 8:00 AM - 9:30 AM CC MC928 Steroids to the Rescue Yarnell Lafortune, M.D., Ezekiel Tayler, D.O., Helen Stutz, D.O., Albany Medical Center, Albany, NY Airway management of the patient with a mediastinal mass requiring general anesthesia is clearly outlined in the literature. We present a case of a patient with newly diagnosed mediastinal Hodgkin's Lymphoma and worsening respiratory distress in the ICU. Subsequent treatment with high dose steroids showed rapid improvement and avoided an airway emergency. Such therapy sheds light on the efficacy of high dose steroids with rapidly progressing mediastinal lymphoma and airway compromise. Tuesday, October 15 8:00 AM - 9:30 AM CC MC929 Laryngospasm Leading to ECMO Rescue Jordan Taylor, M.D., Roman Dudaryk, M.D., University of Miami / Jackson Memorial Hospital, Miami, FL Case Description 36-year-old male status post gun shot wound to left lower extremity went to operating room for ORIF of left femoral condyle. Induction intubation and surgery were smooth and uneventful. Upon extubation patient developed laryngospasm causing severe negative pressure pulmonary edema. He required emergent reintubation and had refractory hypoxia despite exploration of numerous ventilatory options. Vasopressor infusions were required to maintain hemodynamics while CT surgery Copyright © 2013 American Society of Anesthesiologists placed cannulas and initiated V-V ECMO. Patient remained on ECMO with lung protective ventilation until he was weaned to decannulation and eventually walked out of hospital neurologically intact 39 days later. Tuesday, October 15 8:00 AM - 9:30 AM CC MC930 Don’t Get Behind on Compartment Syndrome: A Rare Case of Postoperative Gluteal Compartment Syndrome in the Intensive Care Unit Beth Teegarden, M.D., Hokuto Nishioka, M.D., University of IL Hospital & Health Sciences System, Chicago, IL A morbidly obese male with multiple knee surgeries presented for resection arthroplasty with knee arthrodesis. After a prolonged procedure and significant blood loss the patient was brought to the intensive care unit. Several hours after extubation he complained of pain numbness and weakness in the non-operative lower extremity. With progressively worsening pain in the left buttock a diagnosis of gluteal compartment syndrome and rhabdomyolysis was made. He underwent an emergent fasciotomy and critical care management. For patients with morbid obesity presenting for prolonged procedures anesthesiologists should carefully consider positioning and have a suspicion for compartment syndrome in the perioperative period. Tuesday, October 15 8:00 AM - 9:30 AM CC MC931 Severe Carcinoid Crisis: Touch to Believe Nickole Teel, M.D., Mattew Torre, M.D., Chuanyao Tong, B.A., Wake Forest University School of Medicine, Winston Salem, NC A 56-year-old female with terminal metastatic carcinoid cancer presents for ureteral stent exchange. High dose octreotide was administered before and during surgery. Following induction of anesthesia whole body flushing occurred followed by progressive hypotension and significant ECG changes including sinus tachycardia ST-T elevation complete heart block and widening QRS which did not respond to multiple doses of vasopressors. Palpation of the carotid revealed a bounding pulse and two boluses of nitroglycerin restored the ECG to sinus rhythm. The surgeons were able to complete the procedure. The patient was extubated monitored overnight and discharged home next day Tuesday, October 15 8:00 AM - 9:30 AM CC MC932 Recurrent Cardiac Arrests in the Setting of Severe Illness: A Case Report Yi Cai Isaac Tong, M.D., Joshua Vacanti, M.D., Brigham and Women's Hospital, Boston, MA The patient is a 36-year-old male with 80% total body surface area burn whose course was complicated by recurrent asystolic arrests linked to intractable colonic distention. Following initial stabilization the patient was admitted to the ICU. Several asystolic arrests were seen and thought to be precipitated by changes in respiratory pattern and ventilator dyssynchrony. We suspected that these arrests were linked to severe colonic distention confirmed by abdominal imaging. The patient's distention and asystolic events persisted despite standard promotility interventions. An enteral infusion of polyethylene glycol was initiated resulting in laxation and resolution of the patient's cardiac instability. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM CC MC933 Left Stellate Ganglion Block for the Treatment of Ventricular Tachyarrhythmias in Two Patients Requiring Biventricular Assist Devices for Cardiogenic Shock After Myocardial Infarction Emily Vail, M.D., Thomas Pfeiffer, M.D., Barry Fine, M.D., Ph.D., Staffan Wahlander, M.D., Michael Weinberger, M.D., Columbia University College of Physicians and Surgeons, New York, NY We describe two patients requiring biventricular assist devices for cardiogenic shock and recurrent ventricular arrhythmias after myocardial infarction in whom left stellate ganglion blocks were performed. In one patient the block was effective in terminating arrhythmias and facilitated biventricular assist device explantation. In the other patient whose ventricular arrhythmias were caused by atrial flutter stellate ganglion block failed to terminate ventricular arrhythmias. Both patients experienced adverse effects of stellate ganglion block which were poorly tolerated due to their tenuous clinical status and poor physiologic reserve. Tuesday, October 15 8:00 AM - 9:30 AM CC MC934 Perioperative Management of Brain Dead Female at 17 Weeks Gestation Robert Vietor, M.D., Phillip Mason, San Antonio Uniformed Services Health Education Consortium, San Antonio, TX 24-year-old female status post motor vehicle accident brought to trauma bay with GCS of 3. Intubated and on head CT noted to have severe brain injury with central herniation. On CT of her aorta it was noted she had an intra-uterine pregnancy with EGA of 17 weeks. Patient went to OR for emergent craniectomy. Plan made to keep mother alive until fetus viable for delivery. In this presentation we will discuss issues unique to peri-operative management of pregnant and head injured patients. We will also discuss factors contributing to determining code status in a pregnant brain dead patient. Tuesday, October 15 8:00 AM - 9:30 AM CC MC935 Moya Moya Disease Presenting With Acute Intracranial Hypertension and Acute Pneumomediastinum Jonathan Weaver, M.D., Avinash Kumar, M.D., Vanderbilt University, Nashville, TN A 25-year-old female presented with acute intraparenchymal hemorrhage (due to moyamoya disease). The patient was intubated on admission and had an emergent placement of an external ventricular drain to control intracranial hypertension. During diagnostic angiography and decompressive craniotomy for malignant intracranial hypertension she developed sudden circulatory collapse in spite of a normal intraoperative TEE and with bilateral breath sounds necessitating aggressive hemodynamic resuscitation. She was stabilized and transferred back to the ICU. The cause was found to be a tension mediastinum of unclear etiology. The unusual complication in a medically complex case presented a challenge to management. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 8:00 AM - 9:30 AM CC MC936 Extracorporeal Membrane Oxygenation (ECMO) Support of One-Lung Ventilation During Adult Thoracic Surgery: A Case Series Robert Weaver, M.D., Eric Ashford, M.D., Jeremy Dority, M.D., Zaki-Udin Hassan, M.D., University of Kentucky, Lexington, KY, Michael Harned, M.D., Lexington Clinic, Lexington, KY Extracorporeal Membrane Oxygenation (ECMO) is an intensive treatment used to support patients with severe respiratory or cardiac disease who have failed more conventional means of management. ECMO historically has been utilized in neonates with increasing evidence for adult use. Novel applications for ECMO are increasingly described in the literature for hemodynamic support during surgery with favorable outcomes. We present a case series in which ECMO was utilized during thoracic surgery in three adult patients with severe pulmonary pathology to permit favorable cardiopulmonary conditions during one lung ventilation. MCC Session Number – MCC14 Tuesday, October 15 10:30 AM - 12:00 PM CC MC937 Case Report: A Cerebellar Hematoma From a kKown Arteriovenous Malformation Peter Wong, M.D., Tufts Medical Center, Boston, MA, Jana Hudcova, Lahey Clinic, Burlington, MA A 61-year-old female with a known AVM presented with sudden onset headache altered mental status nausea and vomiting. En route to a referring hospital she was intubated for a GCS of 3. Offical imaging demonstrated significant compression of the brainstem from a large 5 cm cerebellar 4th ventricle hematoma. She had been evaluated neurosurgeon previously but her AVM not amenable to surgical treatment. The patient had been presented the option of radiosurgery but declined. On hospital day 5 her family chose to procede with organ procurement as her prognosis was poor secondary to lack of meaningful neurologic function. Tuesday, October 15 10:30 AM - 12:00 PM CC MC938 Anemia With Hyperbilirubinemia Isolated Azotemia and Altered Mental Status in the Setting of Blood Transfusion in the Trauma Patient Adam Wright, Student, Tufts University School of Medicine, Boston, MA, Jana Hudcova, M.D., Lahey Hospital & Medical Center, Burlington, MA We present the case of an 86-year-old male who fell 25 feet from a ladder sustaining multiple pelvic fractures with hemorrhage as well as multiple spinal and extremity fractures. There was no loss of consciousness or head injury. The patient had a history of blood transfusion reactions with multiple antibodies. Initial treatment included coiling of the left L4 lumbar artery transfusion of multiple blood products and spinal immobilization. His hospital course was complicated by persistent anemia requiring transfusion with subsequent rash elevated bilirubin with jaundice isolated azotemia and persistent altered mental status. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM CC MC939 Anesthetic Management of a Boston Marathon Blast Injury Victim With Family History of Malignant Hyperthermia Huai Jen Yang, M.D., Jeanette Lee, M.D., Bobby Chang, M.D., Roya Saffary, M.D., Boston Medical Center, Boston, MA 65-year-old male presented emergently with a near fatal vascular injury sustained from the Boston Marathon bombing. En route to the OR patient's wife alerted staff about family history of Malignant Hyperthermia. Anesthesia machine was emergently prepared with an activated charcoal filter. Anesthesia was delivered using a trigger-free technique. Intraoperative course was complicated by PEA arrest. Patient was successfully resuscitated. There were no perioperative signs of Malignant Hyperthermia. We discuss the importance of obtaining family history of anesthetic complications and methods of delivering MH trigger free anesthesia in the trauma setting. Tuesday, October 15 10:30 AM - 12:00 PM AM MC940 You Can't Judge a Book By Iis Cover: An Unexpected Difficult Airway in a Patient With Ehlers-Danlos Syndrome Jesse Rojas, M.D., Tilak Raj, M.D., Thomas Tinker, M.D., University of Oklahoma Health Sciences Center, Oklahoma City, OK We present a 19-year-old patient who underwent an arthroscopic knee procedure in our surgery center. During induction of general anesthesia unanticipated difficult airway was encountered. After multiple failed attempts at direct laryngoscopy initial airway patency with mask ventilation became impossible. The patient's airway anatomy forced us to resort to a glidescope-fiberoptic bronchoscope combination to accomplish successful tracheal intubation. Post-intubation we discovered the patient has an unknown variant of the connective tissue disorder Ehlers-Danlos Syndrome. Literature discussing EDS anesthesia and difficult airway management is scarce. We discuss the variants of EDS and implications for anesthesia when they present for surgery. Tuesday, October 15 10:30 AM - 12:00 PM AM MC941 Difficult Airway and Malignant Hyperthermia Eugenio Sabalvoro, M.D., Covenant Hospital, Saginaw, MI The patient is a 24-year-old morbidly obese male for emergent incision and drainage of a left neck abscess. He has a known history of muscle dystrophy mitochondrial myopathy and cardiac dysrhythmias. Tuesday, October 15 10:30 AM - 12:00 PM AM MC942 Takutsubo Syndrome in a Healthy 54-year-old for Orthopedic Surgery Eugenio Sabalvoro, M.D., Covenant Hospital, Saginaw, MI She is a 54-year-old female for knee surgery. A few minutes after spinal she became bradycardic and atropine was given. BP was normal at 120/60 but started coughing frothy secretions and felt short of breath. Intubation was done. Patient was noted to have PEA and epinephrine chest compressions done. Copyright © 2013 American Society of Anesthesiologists BP was immediately achieved but still labile and hypotensive. She was maintained on levophed. DIC panel showed excessive D-dimer after A-line placed. Cath and echo showed takutsubo cardiomyopathy and IABP placed and pressors maintained until patient was stable enough to be extubated and discharged home. Tuesday, October 15 10:30 AM - 12:00 PM AM MC943 Airway Management of a Patient With Port Wine Stain Affecting the Face Keith Schmidt, M.D., Dmitry Voronov, M.S., Ned Nasr, M.D., Cook County Hospital, Chicago, IL, Paulina Voronov, M.D., Lurie Childrens Hospital, Chicago, IL, Magdalena Schmidt, D.O., Rush Hospital, Chicago, IL 5-year-old 22kg Caucasian female with port wine stain affecting the left and right side of the face presented for pulsed die laser therapy. She was otherwise healthy and had seven prior treatments without complication. Anesthesia was administered with Nitrous Oxide and Sevoflurane via face mask then when surgeons were ready an oral airway with a 1/2 precut size 4.5 et tube was strategically placed through the oral airway for ventilation. This technique allowed for greater surgical access and the circuit to be utilized if positive pressure was needed. The case was completed uneventfully. Tuesday, October 15 10:30 AM - 12:00 PM AM MC944 Successful Management of Peripheral Nerve Catheter in a Disabled Patient Tina Sharma, M.D., Igor Tkachenko, M.D., Tariq Malik, M.D., University of Chicago, Chicago, IL Peripheral nerve blockade is an effective mode of pain control in patients undergoing single extremity surgery. Peripheral nerve catheters enhance pain control post-operatively by providing a continuous infusion of local anesthetic. Patients are instructed on the use of the catheter and are sent home with instructions on catheter management. Previously a mentally or physically disabled patient would be a relative contraindication to placing a peripheral nerve catheter due to their inability to manage it after surgery. However we describe a case in which a physically disabled patient had successful analgesia via a peripheral nerve catheter with support from family members. Tuesday, October 15 10:30 AM - 12:00 PM AM MC945 Esophageal Fibrovascular Polyp and Acute Airway Obstruction in the GI Lab Taizoon Dhoon, M.D., Jennifer Gerber, M.D., Thuy Tran, M.D., Karen Sibert, M.D., Cedars-Sinai Medical Center, Los Angeles, CA A 74-year-old man presented with progressive dysphagia and sensation of a foreign body in his throat. PMH was significant for HIV asthma GERD and Zenker's diverticulum. EGD demonstrated a mass in the upper esophagus. The endoscopist opted not to excise the mass and withdrew the endoscope. The patient's airway immediately became obstructed; mask ventilation was impossible. Vocal cords could not be visualized with laryngoscopy. The esophageal mass had prolapsed cephalad into the supraglottic space producing airway obstruction. Emergent tracheostomy was performed. The patient later underwent surgical excision of the mass; pathology revealed giant esophageal fibrovascular polyp. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM AM MC946 Postoperative Vision Lost After Bronchoscopy Spray Cryotherapy Balloon Dilation John Siu, M.D., University of Maryland, Baltimore, MD 22-year-old hx of bilateral lung transplant undergoing repeat balloon dilations with spray cryotherapy(SCT) for bronchial stenosis under general anesthesia. During cycle 4 of SCT expansion of liquid nitrogen gas did not have adequate exhaust pathway building up intrathoracic pressure. The cycle immediately stopped but face lips and tongue turned white for several seconds. Brief drop in end tidal CO2 hemodynamics stable otherwise. Case resumed and completed. Uneventful emergence and extubation. Post-operatively complained of nausea. At 4 hrs after case patient had non-painful bilateral vision loss with acute increased intraocular pressure s/p anterior chamber tap. Blindness resolved in 2 days. Tuesday, October 15 10:30 AM - 12:00 PM AM MC947 Spontaneous Tracheal Tear During a Routine Robotic-Assisted Cholecystectomy Christina Smmith, U of Illinois Chicago, Chicago, IL Tracheobronchial tear represents a rare but serious and potentially fatal complication following endotracheal intubation. Prompt recognition and evaluation of the tracheal injury is crucial. Importantly anesthesiologists are known leaders in patient safety and quality of care by the anesthesia team is not to be discounted in an urgent and critical setting. This report presents one incidence of tracheal injury occurring after routine elective cholecystectomy. The goal is to detail the patient's clinical presentation diagnosis and management of the tracheal tear as well as to examine the quality of care throughout the process in order to identify areas for team improvement. Tuesday, October 15 10:30 AM - 12:00 PM AM MC948 Let Sleeping Dogs Lie: Avoiding Periopertaive Exacerbation of Systemic Mastocytosis Sean Summers, M.D., Tilak Raj, M.D., Gozde Demiralp, M.D., OUHSC, Oklahoma City, OK Systemic mastocytosis is a rare disease prone to exacerbations under general anesthesia and various other conditions. When anesthetizing affected patients care must be taken to avoid flares that risk decreased quality of life or even anaphylactic shock. A 44-year-old female with a history of previous perioperative worsening of her systemic mastocytosis presented to us for a hysteroscopy with endometrial ablation. We discuss the disease its anesthetic implications the Mastocytosis society recommendations and our management of this patient which she claimed was ‘the best anesthetic ever!' Tuesday, October 15 10:30 AM - 12:00 PM AM MC949 Difficult Airway in Hereditary Angioedema Thales Tedoldi, M.D., Anibal Vicuna, M.D., Daniel Kim, M.D., Ligia Mathias, M.D., Ph.D., ISCMSP, Sao Paulo, Brazil, Wilma Forte, M.D., Ph.D., FCMSCSP, Sao Paulo, Brazil A 28-year-old ASA Physical Status II man presented for laparoscopic cholecystectomy. Past history was significant for hypertension and hereditary angioedema. The immunology service recommended Copyright © 2013 American Society of Anesthesiologists perioperative infusion of fresh frozen plasma to reduce the risk of upper airway edema and also provided icatibant (specific antagonist of bradykinin B2 receptors) as a rescue drug. Although patient had some difficult airway predictors (Mallampati Class III and thick neck) the risk of angioedema precluded awake intubation technique. Induction of general anesthesia in head elevation positioning was chosen and patient subsequent course was uneventful. Tuesday, October 15 10:30 AM - 12:00 PM AM MC950 Anesthetic Management of a Patient With Osteogenesis Imperfecta for Elective Repair of Umbilical Hernia Jeffrey Waldman, M.D., Jeffrey Gross, M.D., Nathan Mark, D.O., University of Connecticut Health Center, Farmington, CT A 30-year-old ASA 4 Caucasian female with osteogenesis imperfecta presented for elective repair of umbilical hernia. She was three feet tall and weighed 63kg. Past medical history included restrictive lung disease hypertension and kyphoscoliosis. Airway exam was significant for limited neck extension decreased mouth opening and poor dentition. The patient received general anesthesia for the procedure. Awake tracheal intubation was unsuccessful using a fiberoptic bronchoscope Glidescope and Airtrack laryngoscope. Mask ventilation was difficult and the case was performed with a laryngeal mask airway. Post-operative course was complicated by acute on chronic respiratory failure but the patient recovered without further sequelae. Tuesday, October 15 10:30 AM - 12:00 PM AM MC951 Esophageal Retrieval of Foreign Body With Video Laryngoscope and Magill Forceps After Failed EGD Jeremie Walker, M.D., Matthew Ellison, M.D., WVU, Morgantown, WV A 55-year-old male presents in the middle of the night for esophageal foreign body retrieval (7inch plastic comb) on a full stomach and hemoptysis. After an uncomplicated rapid sequence intubation esophageal retrieval via GI specialists and EGD failed. Given the superior esophageal location of the foreign body a C-Mac video laryngoscope and large Magill forceps were used to dislodge and extract the comb without esophageal insult. Extra aspiration precautions were implemented upon conclusion of the case to minimize aspiration risks Tuesday, October 15 10:30 AM - 12:00 PM AM MC952 Anesthetic Management of Cystinosis Kristal Wilson, M.D., Marjorie Robinson, M.D., University of Louisville, Louisville, KY We present a 30-year-old white male with the rare disease Cystinosis who presented for multiple teeth extraction due to significant dental caries. The patient was diagnosed with this lysosomal storage disorder as a child when he presented with chronic kidney failure later diagnosed as Fanconi syndrome requiring bilateral kidney transplant. Other organ involvement includes vision impairment and chronic pancreatitis. Past surgical history included 7 surgeries all with significant post-operative nausea and vomiting. We present the management of this case along with a literature review discussing the disease its process and anesthetic recommendations. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM AM MC953 Unscheduled Stress Testing Anna Wright, M.D., MetroHealth Hospital Case Western Reserve University, North Olmstead, OH The patient is a 71-year-old woman with history of HTN and HLD who presented for an elective shoulder arthroscopy. Prior stress test 4-5 years ago was reported as \normal\" during PSE evaluation. Interscalene block performed intra-operatively followed by induction. After laryngoscopy she developed tachycardia (HR 120s) associated with concomitant ST depressions confirmed by a 12-lead EKG. Shoulder arthroscopy cancelled and medical management of cardiac ischemia ensued. A cardiac catheterization was performed and patient scheduled for CABG of 3 vessels. Intra-aortic balloon pump placed pre-operatively prior to surgery. Complicated course of CABG followed by prolonged SICU stay." Tuesday, October 15 10:30 AM - 12:00 PM AM MC954 A Case Report: Difficult Ventilation and Hypercapnia Narcosis in a Patient With Relapsing Polychondritis Undergoing Bronchoscopic Intervention Jiang Wu, M.D., Ursula Galway, M.D., Cleveland Clinic, Cleveland, OH Patients with Relapsing polychondritis (RP) are at risk of difficult oxygenation intubation ventilation and extubation due to both upper and lower airway destruction and collapse. We report the airway management of a RP patient with past anesthetic history of sudden difficult ventilation via an endotracheal tube (ETT) inserted through tracheostomy stoma resulting in 15 min of hypoxemia and hypercarbia during his previous bronchoscopy. We demonstrate the importance of establishing a reliable airway and maintaining positive end expiratory pressure to keep airways open in correcting poor oxygenation ventilation and hypercapnia narcosis during his next bronchoscopic airway interventions. Tuesday, October 15 10:30 AM - 12:00 PM AM MC955 Asystole During an Elective Laparoscopic Procedure Huai Jen Yang, M.D., Oleg Guszkov, M.D., Roberto Ballivian, M.D., Vahila Pamidimukkala, M.D., Boston Medical Center, Boston, MA A healthy 44-year-old woman suffered cardiac arrest during laparoscopic hysterectomy; deflation of peritonenium and CPR were required to reinitiate cardiac rhythm. Patient was rescheduled for open hysterectomy. Precautious steps were taken and surgery completed without complication. Several cases of cardiovascular collapse during gynecologic laparoscopic procedures have been reported. Nearly all the episodes occurred during CO2 insufflation or with traction on pelvic structures. Causes for cardiovascular collapse include hypercapnia anoxia decreased venous return secondary to elevated intra-abdominal pressure gas embolism and profound vagal response. By promptly recognizing and treating these complications the surgical and anesthesia teams can minimize morbidity and mortality. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC956 Rhabdomyolysis After Prolonged Surgery: A Case Report and Literature Review Mary Kelly, M.D., Jingping Wang, M.D., Ph.D., Massachusetts General Hospital, Boston, MA Presented is a case of rhabdomyolysis in a 30-year-old patient following a 16 hour surgery consisting of a LeFort I osteotomy bilateral arthroplasties and bilateral TMJ total joint replacements. Upon postoperative admission to the SICU two large pressure ulcers were noted consisting of 10x12cm nonblanchable area on coccyx/buttock and an 18x5cm non-blanchable area on left scapula. CPK was 33 000 and he was diagnosed with rhabdomyolysis. The patient was treated promptly with large volumes of hydration forced diuresis and alkalization when appropriate. The patient fully recovered. Risk factors and treatment for intraoperative rhabdomyolysis are discussed. Tuesday, October 15 10:30 AM - 12:00 PM FA MC957 Elevated End Tidal Carbon Dioxide Intraoperatively: A Diagnostic Dilemma Nicole Khetani, M.D., Tara Kennedy, M.D., Michele Mele, M.D., Thomas Jefferson University Hospital, Philadelphia, PA A 32-year-old 158 kg male with morbid obesity recurrent pulmonary embolism and schizophrenia on antipsychotics underwent a posterior thoracic decompression and fusion for spinal stenosis. Remifentanil and propofol were used for induction and maintenance. Fifteen minutes before surgery end the maintenance agents were switched to Desflurane. Within thirty minutes of Desflurane use rigors and tachypnea with a minute ventilation up to 24L/minute were noted. Core temperature rose to 39.3°C. Malignant hyperthermia was suspected but an arterial blood gas revealed only respiratory acidosis. We review precipitating factors and the differential diagnosis for intraoperative rigors fever and hypercarbia. Tuesday, October 15 10:30 AM - 12:00 PM FA MC958 Intraoperative Adrenergic Crisis Ellen Freire, M.D., Daniel Kim, M.D., Christiano Matsui, M.D., Ligia Mathias, M.D., Ph.D., ISCMSP, Sao Paulo, Brazil A 42-year-old ASA Physical Status I man presented for total hip arthroplasty. He had undergone three uneventful hip surgeries before. Following epidural catheter placement and induction of general anesthesia the patient presented sinus tachycardia arterial hypertension and hypercapnia. Surgical procedure was postponed and in the following hours he developed hyperthermia and acute pulmonary edema. As malignant hyperthermia was suspected dantrolene was given unsuccessfully and patient died fourteen hours later. Necroscopy found bilateral tumors in suprarenal gland and medullary thyroid cancer with final diagnosis of Multiple Endocrine Neoplasia type 2A. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC959 Digoxin Toxicity in a 90-year-old Gentleman Following Open Reduction Internal Fixation of Left Femoral Neck Fracture Michael Kim, M.D., Roya Saffary, M.D., Carlos Guzman, M.D., Boston Medical Center, Boston, MA Timothy Woodward, B.S., Boston University School of Medicine, Boston, MA Digoxin toxicity is a commonly encountered adverse drug reaction largely attributed to its narrow therapeutic window which is affected by a multitude of interacting factors. Essentially every known arrhythmia can manifest as a result of digoxin toxicity. We present a case of an elderly patient who developed an accelerated idioventricular rhythm immediately after a routine orthopedic surgery and was found to have an elevation in serum digoxin levels necessitating Digibind therapy. This report discusses the potential for intraoperative pharmacokinetic interactions resulting in post-operative digoxin cardiotoxicity emphasizing the importance of early post-operative recognition of digoxin toxicity in the high-risk elderly population. Tuesday, October 15 10:30 AM - 12:00 PM FA MC960 Factors Affecting Outcomes After Perioperative Advanced Cardiovascular Life Support Michelle Kim, M.D., Daniella Smith, M.D., University of Maryland Medical Center, Baltimore, MD Two weeks after a cadaveric liver transplant a 50-year-old female presented with an acute hepatic artery thrombosis and partial hepatic infarction. Interventional Radiology was unable to re-establish hepatic artery blood flow and a large peri-hepatic hematoma developed. Fulminant hepatic failure ensued and the patient became increasingly acidotic and hypotensive. Shortly after emergent laparotomy was performed the patient became severely hypotensive and asystolic. Advanced Circulatory Life Support (ACLS) and massive blood transfusion were instituted with only transient restoration of circulation. After 55 minutes and six rounds of ACLS the decision was made to cease our efforts. Tuesday, October 15 10:30 AM - 12:00 PM FA MC961 Anesthetic Management of Laparoscopic Adrenalectomy for Pheochromocytoma Francis Kirk, M.D., Aaron LacKamp, M.D., Johns Hopkins Hospital, Baltimore, MD We provided general anesthesia for a 27-year-old woman undergoing a laparoscopic adrenalectomy for pheochromocytoma. Preoperatively she was managed for 8 weeks with phenoxybenzamine and propranolol. The patient was premedicated with midazolam and fentanyl and a radial arterial line was placed. General anesthesia was induced with remifentanil propofol and vecuronium. The airway was secured and another large peripheral IV was placed. Anesthesia was maintained with isoflurane and remifentanil. Blood pressure was labile during insufflation surgical manipulation and adrenal vein ligation. Vasoactive infusions were prepared but not initiated. The patient was extubated and transferred to the ICU for observation. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC962 TTE Video Demonstrating Massive Thrombus Saman Kohanof, D.O., Davide Cattano, M.D., UT Houston Medical Center, Houston, TX Our Patient CC is a 77-year-old male with numerous medical problems including atrial fibrillation was scheduled for a tracheostomy after initially being admitted for a severe ischemic stroke which required intubation to secure his airway. Shortly after being moved to the OR table the patient became hemodynamically unstable end tidal carbon dioxide dropped off and chest compressions were started. An Intraoperative TEE was preformed which showed what appears to be a massive thrombus in the right atrium and right ventricle. Tuesday, October 15 10:30 AM - 12:00 PM FA MC963 Does Inhalational Heroin Abuse Matter? A Case of Pneumothorax and Tracheal Tear in a Patient With Tracheal Stenosis. Fathima Kolonda, M.D., Hokuto Nishioka, M.D., University of Illinois- Chicago, Chicago, IL A 38-year-old female with tracheal stenosis presented for laser excision of her stenosis under jet ventilation. Her medical history included asthma and chronic inhalational heroin abuse. Though appropriate jet ventilation techniques were used the patient developed a pneumothorax which was promptly decompressed. Because of the complication a tracheostomy tube was placed but after multiple failed attempts at ventilation a tear in the posterior tracheal wall was identified. To better understand why these complications occurred we reviewed jet ventilation techniques risk factors and complications in patients with inhalational drug abuse history. Tuesday, October 15 10:30 AM - 12:00 PM FA MC964 A Case of Airway Bleeding Managed by Embolization Meri Koski, D.O., Kamal Maheshwari, M.D., Hesham Elsharkawy, M.D., M.S., Wael Ali Sakr Esa, M.D., Ph.D., Cleveland Clinic, Cleveland, OH A 34-year-old male with a past medical history significant for bilateral pulmonary artery aneurysms was scheduled for a bronchoscopy for new onset hemoptysis. During the procedure fresh blood was found in the right mainstem and bronchus intermedius. Cauterization was unsuccessful. The patient was intubated and a bronchial blocker was placed in the right mainstem bronchus. The patient was taken emergently to interventional radiology for an angiogram with successful embolization of the right intercostal bronchial trunk. The patient was transported to the ICU in stable condition with the bronchial blocker in place which was removed 24 hours later. Tuesday, October 15 10:30 AM - 12:00 PM FA MC965 Pseudocholinesterase Deficiency Rohini Kotha, M.B. B.S., Li Meng, M.D., University of Pittsburgh, Pittsburgh, PA 63-year-old F with PMH of obesity htn was scheduled for Kyphoplasty (T7-8). Induction of anesthesia was uneventful with propofol and succinylcholine. Subsequently 30mg of rocuronium was adminstered. Pt remained paralysed with no twitches for about 4hrs after which she developed a fade response on a Copyright © 2013 American Society of Anesthesiologists TOF 2/4. Upon reversal with neostigmine and glycopyrollate TOF was noted to be diminshed 1/4. Her cholinesterase level and Dibucaine number were 352 and 33 respectively. She remained apneic and was electively sedated and remained intubated for 12hrs after which she was extubated and recovered safely. Tuesday, October 15 10:30 AM - 12:00 PM FA MC966 Supine Hypotensive Syndrome - But She's Not Pregnant Daniel Kovacs, Andrea Strathman, M.D., Wake Forest Baptist Health, Winston-Salem, NC 50-year-old F with a h/o MV regurgitation s/p MVR CHF beta-thalassemia and morbid obesity scheduled for exploratory laparotomy. Imaging demonstrated a 40cm multiseptated mass which arose from the ovary extending into an abdominal wall hernia which contained part of the left lobe of the liver and bowel with IVC compression and ascites noted. On exam the patient was hypotensive and hypoxic when supine. The case was complicated by hypoxemia and difficultly with ventilation requiring high PEEP multiple ventilator maneuvers and fiberoptic confirmation of ETT placement. The patient required extensive resuscitation vasopressor use with the successful resection of a 26kg mass. Tuesday, October 15 10:30 AM - 12:00 PM FA MC967 The Anesthestic Considerations for the Placement of a Diaphragmatic Pacemaker in a Patient With ALS Molly Kraus, M.D., Lopa Misra, D.O., Kristi Harold, M.D., Mayo Clinic, Phoenix, AZ The diaphragm pacing system is a device that stimulates the diaphragm to maximally contract so patients can breath more effectively. A fifty-year-old female recently diagnosed with ALS presented for a diaphragmatic pacer insertion. From an anesthetic perspective both the surgery and the patient population present several unique challenges. Since the surgeon laparoscopically tests muscle contraction of the diaphragm for placement of electrodes paralytics cannot be used. Remifentanil an ultra-short-acting opoid provides a superb adjunct to sevoflurane. Remifentanil depresses the respiratory drive which facilitates mapping of the diaphragm so the patient will not augment respiration. Tuesday, October 15 10:30 AM - 12:00 PM FA MC968 Iatrogenic Airway Foreign Body During Rigid Bronchoscopy in a Two-Year-Old Girl Jason Kreiner, M.D., Tigran Sukiasyan, M.D., Joshua Silverman, M.D., Erica Lai, SUNY Health Science Center at Brooklyn, New York, NY We present the case of a two-year-old girl who underwent a rigid bronchoscopy which resulted in an iatrogenic airway foreign body. This case highlights the importance of routine instrument inspection and iatrogenic foreign body aspiration as a possible postoperative diagnosis. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC969 Case of Malignant Hyperthermia Alan Kulig, M.D., Baystate Medical Center, Springfield, MA A 41-year-old female with a difficult airway and unremarkable personal and family anesthetic history presented for a laparoscopic gastric bypass. The patient was induced with propofol and succinylcholine and maintained on O2 N20 and sevoflurane. Vital signs were stable throughout. The ETCO2 and temperature increased slightly during the first two hours of surgery but markedly increased between 2.5 and 4 hours. The MH protocol was initiated with prompt normalization of both ETO2 and temperature. The patient remained intubated and sedated overnight and was extubated the following morning without sequellae. Subsequent muscle biopsies tested positive for MH. Tuesday, October 15 10:30 AM - 12:00 PM FA MC970 Anesthetic Management for Amiodarone-Induced Thyrotoxicosis Complicated by Failed Medical Therapy: A Case Report Catherine Kuza, M.D., Antonio Aponte-Feliciano, M.D., University of Massachusetts Medical School, Worcester, MA A 60-year-old morbidly obese female with a past medical history of pulmonary hypertension ventricular tachycardia atrial fibrillation (s/p ablation) and congestive heart failure presented with amiodaroneinduced thyrotoxicosis (AIT) and neutropenia secondary to methimazole treatment. Methimazole proved to be an ineffective and potentially lethal medical treatment. She was treated with filgrastim potassium iodide sotalol and methylprednisolone without salutary effects. An urgent total thyroidectomy was performed. We present the perioperative and airway management of a challenging patient with amiodarone-induced thyrotoxicosis and review the literature on the safety of performing anesthesia in these patients. Tuesday, October 15 10:30 AM - 12:00 PM FA MC971 Management of Pheochromocytoma in a Patient With Fontan Circulation Kathleen Kwiatt, D.O., David Fish, M.D., Cooper University Hospital, Camden, NJ A 26-year-old patient with completed Fontan circulation presented for resection of pheochromocytoma under general anesthesia. The patient was pre-medicated with phenoxybenzamine yet experienced complications related to both acute and chronic excess catecholamine exposure. She experienced extreme hemodynamic variation the treatment of which required diligent awareness of her underlying congenital heart disease with passive pulmonary circulation. Hypertension was managed primarily with clevidipine and hypotension required norepinephrine phenylephrine and epinephrine in addition to resuscitation with IV fluid and blood. The patient ultimately tolerated the procedure and was discharged to home 8 days post-operatively. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC972 Pre and Perioperative Management of Suspected Multiple Endocrine Neoplasia Men in a 54-year-old African American Woman Jeanne Ky, B.S., Kimberly McClelland, M.P.H., Richard Barrett, M.S., David Holliday, M.D., Clairmont Griffith, M.D., Howard University College of Medicine/ Hospital, Washington, DC The pre- and perioperative management of MEN requires consideration of thyroid parathyroid and adrenal gland physiology as well as efficient application of anesthesiology fundamentals. We present a 54-year-old African-American female with a past medical history of SLE NIDDM hypertension dyslipidemia CVA (x2) and CHF who presented with hypertensive emergency headache and retrosternal chest pain unrelieved by aspirin. An enlarged thyroid was noted upon exam and after cardiac stabilization the patient received a neck CT showing a large mass and an abdominal CT showing an adrenal gland mass and an intrauterine fibroid. She was subsequently diagnosed with pheochromocytoma and underwent adrenalectomy. Tuesday, October 15 10:30 AM - 12:00 PM FA MC973 Profound Systemic Reaction After Bone Cement Application in Total Knee Arthroplasty Robert LaCivita, M.D., Avichai Dukshtein, M.D., Piyush Gupta, M.D., Maimonides Medical Center, New York, NY A 61-year-old patient with past medical history of nonischemic dilated cardiomyopathy presented for elective left knee replacement. Spinal anesthesia was administered as the main anesthetic. Application of bone cement resulted in profound hypotension initially refractory to various resuscitative treatments. The patient also developed difficulty in speech associated with swelling of the mouth and tongue. The patient regained hemodynamic stability with epinephrine and antihistamines. Histamine and tryptase level drawn at this time were elevated suggesting that patient likely had an anaphylactic reaction to bone cement. Tuesday, October 15 10:30 AM - 12:00 PM FA MC974 Ability to Perform a Needle Cricothyrotomy: An Essential Skill for Every Anesthesiologist Anjana Lal, M.D., Carl Adkins, M.D.,UT Southwestern Medical Center at Dallas, Dallas, TX, Chinwe Ononogbu, C.R.N.A., Parkland Hospital, Dallas, TX A 64-year-old male with prior neck dissection/radiation wound dehiscence and Mallampati IV airway presents for GI Suite procedure. After induction and paralysis bag/mask ventilation is difficult but not impossible. Initial attempt to intubate with Glidescope® is unsuccessful. Next a bougie cannot be passed into the trachea. Subsequently ventilation with both bag/mask and LMA becomes impossible. Needle cricothyrotomy is performed with 16-guage angiocath 3 mL syringe barrel and 7.0 ETT adapter which is attached to the machine breathing circuit. ENT surgeons arrive and perform endotracheal intubation via endoscopic guidance. Patient is transported to ICU in stable condition. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC975 Trauma and Hemorrhagic Shock: The Dangers of Intra-Arterial Massive Transfusion Agnes Lamon, M.D., Seema Kamisetti, D.O., Sanford Littwin, M.D., St. Luke's- Roosevelt Hospital Center, New York, NY This is a 56-year-old male in hemorrhagic shock from bilateral lower extremity traumatic amputations. He was intubated and resuscitated with 10 UPRBC's and 1U platelets through a femoral line by ED personnel. Unbeknownst to the anesthesia provider this line was an intra-arterial cordis. Upon arrival to the OR he was tachycardic in the 140's and hypotensive with systolic blood pressures in the 50's. Once a subclavian central line was placed and additional blood products were transfused intravenously the patient's condition drastically improved. This case reviews the physiologic changes associated with arterial transfusions and the pronounced improvement following appropriate venous access. Tuesday, October 15 10:30 AM - 12:00 PM FA MC976 What is a Reninoma? Alice Landrum, M.D., Martha Schuessler, B.S., Alan Zaggy, M.D., Sarah Schaak, C.R.N.A., University of Missouri-Columbia, Columbia, MO An 18-year-old female presented for robotic laparoscopic resection of a renal mass. The patient had developed malignant hypertension one year ago. Extensive workup including a saline suppression test ultrasounds CT angiography MRI and renal vein sampling revealed a mass in the upper pole of the right kidney which was secreting renin. A reninoma is an extremely rare cause of severe hypertension. Resection may be curative but careful attention must be paid to preoperative management of hydration and blood pressure as well as during the immediate post resection phase when residual renin may still be in the circulation. Tuesday, October 15 10:30 AM - 12:00 PM FA MC977 Management of Upper Airway Trauma Ryan Laterza, M.D., Mount Sinai Medical Center, New York, NY The anesthesiology resident was called to the Emergency Department. Upon arrival he discovered a trauma victim who suffered severe oral maxillary trauma after being struck by a motor vehicle. The emergency medicine physicians were attempting to intubate with a video laryngoscope but their attempts were futile secondary to blood and debris obstructing the camera. The anesthesiology resident performed a direct laryngoscopy with a Macintosh 3 blade. On laryngoscopy the oropharynx was completely saturated with blood and a yankauer was used to suction the oropharynx yielding enough time for the glottic opening to be visualized and the patient was successfully intubated. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC978 Acute Hemorrhage in an Awake Patient Leading to Bezold-Jarisch Reflex and Conversion to General Anesthesia Sarah Latif, M.D., Jeremi Mountjoy, M.D., Paul Alfille, M.D., Massachusetts General Hospital, Boston, MA A 63-year-old male underwent a femoral artery exploration under spinal anesthesia. An episode of massive and unexpected blood loss occurred during which time the patient was initially hemodynamically stable. However a delayed yet abrupt episode of bradycardia hypotension and nausea followed leading to an unplanned conversion to general anesthesia. The Bezold-Jarisch reflex which leads to vagal stimulation and withdrawal of sympathetic tone in times of severe hypovolemia was thought to be the culprit of the sudden hemodynamic changes. After aggressive resuscitation with intravenous fluids and blood products the patient was extubated and had a stable post-operative recovery. Tuesday, October 15 10:30 AM - 12:00 PM FA MC979 Anesthesia Management of Broncho-Esophageal Fistula Robert Lehn, M.D., Evan Burke, M.D., Jeffrey Gross, M.D., University of Connecticut, Farmington, CT A 65-year-old-man with a history of esophagogastrectomy for esophageal cancer presented with pneumonia. Bronchoscopy diagnosed a distal bronchoesophageal fistula but the procedure was aborted before the site was identified because of copious gastric secretions in the airway. Repeat anesthesia was required for esophageal stent placement. To avoid gastric inflation we kept the patient breathing spontaneously with a small dose of propofol and sevoflurane; because the fistula site was unknown we used a single lumen ETT during esophagoscopy which was completed uneventfully. When CO2 was insufflated during endoscopy end-tidal CO2 rose to 300 mmHg confirming the widely-patent esophagobronchial fistula. Tuesday, October 15 10:30 AM - 12:00 PM FA MC980 Perioperative Management of Severe Aortic Stenosis During Whipple Procedure Pulsar Li, D.O., Richard McAffee, M.D., UPMC, Pittsburgh, PA 71-year-old F w h/o asymptomatic severe aortic stenosis (AV area 0.6 cm 2) with pancreatic adenocarcinoma for robotic-assisted whipple. Though the patient's cardiologist recommended against surgery due to high perioperative mortality risk the surgeon consulted cardiac anesthesia for additional evaluation. In the preoperative clinic after we led a comprehensive discussion and reconciliation of the conflicting views of her cardiologist and surgeon the patient chose to proceed with the significant risk of surgery over palliation and hospice. She underwent uneventful open whipple with uneventful ICU recovery. One year later she underwent successful aortic valve replacement for symptomatic AS. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC981 Spontaneous Vertebral Artery Aneurysm Rupture in a Patient With Neurofibromatosis Type 1 Causing a Difficult Airway Susan Lien, M.D., Jeanine Wiener-Kronish, M.D., Mazen Maktabi, M.B. B.Ch., Massachusetts General Hospital, Boston, MA Vascular abnormalities have been described in neurofibromatosis type 1 (NF1) patients. Vertebral artery (VA) aneurysms however are a rare finding. We report a case of a 26-year-old female with NF1 and a left VA aneurysm who developed acute neck swelling and respiratory distress. Mask ventilation and intubation proved impossible and an emergent surgical airway was obtained. CT head/neck revealed rupture of the VA aneurysm causing a large retropharyngeal hematoma. The patient underwent emergent coiling of the ruptured aneurysm and survived with minimal neurological deficits. This case demonstrates successful teamwork in application of the difficult airway algorithm and crisis management. Tuesday, October 15 10:30 AM - 12:00 PM FA MC982 Intraoperative Hyperthermia as Initial Presentation of Babesiosis Acquired Through Blood Transfusion Melanie Liu, M.D., Marcelle Blessing, M.D., Yale New Haven Hospital, New Haven, CT A 66-year-old woman presented for robotic hysterectomy under general endotracheal anesthesia. Preoperative temperature was 36.4°C. Shortly after induction patient was noted to be hyperthermic to 39.4°C. All inhalational agents were stopped and patient was actively cooled to 37.4°C. No muscle rigidity metabolic acidosis or hypercarbia were noted however hematocrit had fallen to 26 from 32 preoperatively. Further workup revealed hemolytic anemia and blood smear positive for inclusion bodies. Patient was diagnosed with babesiosis likely acquired through recent blood transfusion. She received a full course of treatment for babesiosis and subsequently underwent robotic hysterectomy under general endotracheal anesthesia without further complications. Tuesday, October 15 10:30 AM - 12:00 PM FA MC983 Unique Airway Challenge for Excision of a Middle Mediastinal Mass Excision via Thoracotomy: Severe Tracheal Deviation and Congenital Tracheal Anomaly Andrew Lobonc, M.D., Lavinia Kolarczyk, M.D., UNC at Chapel Hill, Chapel Hill, NC A 78-year-old male with history of hypertension and gastroesophageal reflux disease presented with acute dysphonia. He was found to have a large middle mediastinal mass suspicious for esophageal duplication cyst. He was brought to the operating room for vocal cord injection right thoracotomy and resection of the mediastinal mass. Left sided double lumen tube placement was difficult due to tracheal deviation and final positioning was complicated by abnormal anatomy. The right upper lobe bronchus originated from the distal trachea. This anomaly would not have allowed for lung isolation with a bronchial blocker in the right main stem bronchus. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC984 Iatrogenic Hypernatremia to Treat Severe Cerebral Edema During Liver Transplantation Brett Longlais, Elif Cingi, M.D., University of Minnesota, Minneapolis, MN 41-year-old female patient with end stage liver disease secondary to Acetaminophen overdose admitted for orthotropic liver transplantation. Patient had cerebral edema; brainstem dysfunction acute renal failure and MELD score of 46. Neurosurgery suggested maintaining the goal of pCO2 30-35 and Na 155165 to avoid brain herniation. Hypertonic saline therapy was initiated. Concerns regarding fluid overload during the transplant a HD catheter placed with plans to do HD. Hypertonic saline infusion was used to maintain hypernatremia during a surgery known for large fluid and electrolyte shifts. Transplantation was successful and she was discharged to a long term care facility. Tuesday, October 15 10:30 AM - 12:00 PM FA MC985 Anesthetic Management of a Pheochromocytoma With ACTH Secreting Properties Brandon Lopez, M.D., Christopher Cropsey, M.D., Liza Weavind, M.B. B.Ch., Vanderbilt Medical Center, Nashville, TN A 37-year-old female presented with acute hypoxia hypertension hyperglycemia and elevated cardiac enzymes. History and physical exam revealed abdominal distention weight loss and night sweats. Abdominal CT scan confirmed a 15 cm left adrenal mass. Her preoperative hospital course was complicated by severe hyperglycemia multiple hypertensive episodes and flash pulmonary edema. During surgical resection she experienced extremely labile blood pressure despite maximal therapies. Postoperatively the patient had severe refractory hypotension for several hours prior to normalization. Pathology revealed a pheochromocytoma with both catecholamine and ACTH secreting properties. Tuesday, October 15 10:30 AM - 12:00 PM FA MC986 Cardiovascular Collapse From Traumatic Placement of Chest Tube Status Post Robotic Assisted Thoracoscopic Surgery Daniel Loren, M.D., University of Connecticut Medical Center, Farmington, CT, Rabi Panigrahi, M.D., Hartford Hospital, Hartford, CT 34-year-old woman presented to the hospital for robotic assisted thoracoscopic surgery for upper lobe resection. The case was uneventful until closing of skin wounds and bolusing of epidural catheter. Patient subsequently developed cardiovascular collapse and CPR was initiated along with aggressive resuscitation measures. Diagnosis of hemorrhagic shock confirmed after placement of transesophageal echocardiography probe. After emergent thoracotomy performed and repair of pulmonary artery injury patient was stabilized and transferred to the ICU. She was extubated one day later and eventually discharged from the hospital without any further sequelae. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC987 Airway Management in Penetrating Neck Injury: Asleep Fibreoptic Intubation in a Spontaneous Breathing Patient Using TIVA Peta Lorraway, Anton Booth, FANZCA, Princess Alexandra Hospital, Brisbane, Australia A 19-year-old woman presented with an anterior neck laceration after a self harm episode with a knife. She was maintaining her airway despite an obvious air leak from the wound. Urgent airway management was arranged in theatre with ENT surgeons present. General anesthesia was induced and spontaneous ventilation successfully maintained using propfol TCI. At an adequate depth laryngoscopy was performed and co-phenylcaine applied to the glottis. A fibreoptic bronchoscope successfully guided an ETT below the laceration. The procedure was smooth and uneventful. Surgical exploration revealed an isolated cricothyroid laceration through which a cricothyroidotomy tube was placed for ongoing management. Tuesday, October 15 10:30 AM - 12:00 PM FA MC988 The importance of Teamwork in Managing a Difficult Intubation With a Hunsaker Tube Rohit Mahajan, M.D., University of Michigan, Ann Arbor, MI A 46-year-old female with a history of subglottic stenosis presented for balloon dilation. Intubation was attempted using a CMAC. Despite a Cormack-Lehane grade 1 view a Hunsaker tube was unable to be passed due to an anterior glottis and lack of maneuverability of the floppy tube. Our Otolaryngology colleagues were also unable to pass the tube using suspension laryngoscopy. Ultimately the Hunsaker tube was placed within a 6.5 ETT with a longitudinal slit from end to end. The combined device was passed through the glottis and the overlying 6.5 ETT was peeled off leaving the Hunsaker in place. Tuesday, October 15 10:30 AM - 12:00 PM FA MC989 Pheochromocytoma With Multiple Co-Morbidities Parul Maheshwari, M.D., Praveen Maheshwari, M.D., Srikanth Sridhar, M.D., University of Texas, Houston, TX 47-year-old female with pheochromocytoma for excision.

Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC990 Autologous Blood in Healthy Bone Marrow Donors: What Triggers Transfusion? Solmaz Manuel, M.D., Yumiko Ishizawa, M.D., Ph.D., Massachusetts General Hospital, Boston, MA Preoperative autologous blood donation is frequently offered to bone marrow donors. When transfusion is necessary autologous blood protects against hemolytic febrile or allergic transfusion reactions. Risks of autologous blood transfusion however include clerical error bacterial contamination hemolysis of stored units volume overload of transfusion and TRALI. Furthermore although increasing evidence suggests that a restrictive allogenic blood transfusion strategy decreases morbidity and mortality long-term outcomes in patients receiving autologous transfusion is not known. This case report examines the role of preoperative autologous blood donation in a healthy 36-year-old male bone marrow donor and the decision to transfuse during this procedure. Tuesday, October 15 10:30 AM - 12:00 PM FA MC991 Planned Laparoscopic Cholecystectomy Status Post Aortic Balloon Valvuloplasty With Residual Severe Aortic Stenosis Michael Marotta, M.D., The Mount Sinai Hospital, New York, NY An 89-year-old female presents for a laparoscopic cholecystectomy for pericholecystic abscess. The patient has recently undergone a balloon valvuloplasty for sever aortic stenosis resulting in a post balloon valve area of 0.9cm sq. The patients past medical history is also significant for hypertension coronary artery disease aortic aneurysm hyperlipidemia and GERD. In addition to concerns raised by the patient's comorbidities the surgeon predicts the case will be technically challenging and would like to discuss an open versus the planned laparoscopic approach. Tuesday, October 15 10:30 AM - 12:00 PM FA MC992 Cardiac Complications Related to Postoperative Nausea and Vomiting (PONV) Prophylaxis Kimberly McClelland, M.P.H., Richard Barrett, M.S., David Holliday, M.D., Clairmont Griffith, M.D., Howard University Hospital /Howard College of Medicine, Washington, DC PONV prophylaxis has become a mainstay in perioperative anesthesiology. In the case presented a 22year-old African-American G3P2002 scheduled for a D&C as a result of a missed abortion experienced retrosternal chest pain with ST-segment depression and elevated troponins (3.9 ng/mL) after receiving ondansetron and metoclopramide. The patient received a 2-D echocardiogram showing normal ventricular function and an ejection fraction of 60-65%; cardiac catheterization showed normal coronary arteries. Her ST-segment depression resolved on subsequent EKGs and her troponins normalized over the next 48 hours. Following resolution of chest pain with normal EKG findings a diagnosis of coronary artery spasm was made. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC993 Propofol Increases Risk for Severe Bradycardia Progressing to Sinus Pause With Spontaneous Resolution During Induction of General Anesthesia Brian McClure, D.O., Ashraf Farag, M.D., Cooper Phillips, M.D., Texas Tech University Health Sciences Center, Lubbock, TX An otherwise healthy 42-year-old male underwent induction of general anesthesia using propofol dosed at 2 mg/kg for an open reduction of a tibial fracture. The patient was not on any medication prior to the procedure. Immediately after induction with propofol the patient developed profound bradycardia progressing to a brief sinus arrest which quickly resolved without additional drug therapy. At the time of the sinus arrest direct laryngoscopy was initiated and the patients pulse returned to normal. It is the authors' belief that the laryngoscopy and intubation provided the stimulation necessary to regain spontaneous elevation of the heart rate. Tuesday, October 15 10:30 AM - 12:00 PM FA MC994 General Anesthesia in an Adult With Rubinstein-Taybi Syndrome Steven McGrath, M.D., James Heitz, M.D., Thomas Jefferson University Hospital, Philadelphia, PA A 34-year-old woman presented for multiple dental extractions with general anesthesia. Past medical history was significant for Rubinstein-Taybi Syndrome a rare autosomal dominant genetic disorder with multiorgan involvement including severe cognitive impairment and craniofacial abnormalities. Additionally afflicted individuals may have congenital cardiac conduction abnormalities with documented adverse reactions to Succinylcholine and vasoactive drugs. Furthermore these patients can have severe gastroesophageal reflux and poor pulmonary reserve with histories of recurrent pneumonias. Familiarity with Rubinstein-Taybi Syndrome and its myriad of anesthetic implications beyond difficult airway management is crucial for safe perioperative management of these challenging patients. Tuesday, October 15 10:30 AM - 12:00 PM FA MC995 Continuous Spinal Anesthesia in a Patient With Severe Pulmonary Hypertension Janette McVey, M.D., Melanie McMurry, M.D., University of Missouri, Columbia, MO A patient with an open ankle fracture was scheduled for emergent internal fixation of her fracture. Her past medical history was extensive and included severe pulmonary hypertension. Mean pulmonary pressures were 40-42 mmHg. After an arterial line was secured a continuous spinal catheter was placed and dosed incrementally with 0.5% isobaric bupivacaine until surgical anesthesia was achieved. A vasopressin infusion was started and adjusted as needed to maintain her blood pressures at her baseline. A dexmedetomidine infusion was started to alleviate anxiety during the surgery. The patient tolerated the anesthetic well and had no respiratory compromise during the surgery. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC996 Truth is Stranger Than the Fiction: Impact of Preoperative Assessment on Diagnosis of a Rare Condition Anthony McPherson, M.D., Gozde Demiralp, M.D., University of Oklahoma, Oklahoma City, OK We would like to present you a challenging preoperative assessment of a rare condition. A 54-year-old female who was being assessed for an uro-gynecological procedure reported to have recurrent Bell's Palsy after every surgery. However further investigation reflected more complicated central nervous system pathology involving a familial heritage and hemiplegia. Preoperative work up for transient ischemic attack and stroke were negative. Via referral to Neurology patient was diagnosed with Hemiplegic Migraine. She was prescribed Nimlodipine and was given preemptively during perioperative stage. For the first time in 5 years she was successfully discharged home without any complications. Tuesday, October 15 10:30 AM - 12:00 PM FA MC997 Difficult Emergency Airway Management in Osteitis Fibrosa Cystica Joshua Melvin, Stanford, Santa Clara, CA The patient is a 30-year-old woman with history of ESRD complicated by secondary hyperparathyroidism hospitalized for shortness of breath attributable to severe mitral regurgitation secondary to bacterial endocarditis. Twelve hours after admission she was tachypneic to the thirties with a pulse oximeter saturation of 80%. Upon observation the patient had severe facial deformity with extreme bony enlargement of the mandible maxilla and frontal bones; she had a flattened nose spreading of the teeth and protrusion of the palate. The difficult airway cart was called for as a size 3 video laryngoscope could not reach the vallecula. Tuesday, October 15 10:30 AM - 12:00 PM FA MC998 Safe and Successful Utilization of an LMA With Muscle Paralysis and Mechanical Ventilation in the Event of Unsuccessful Tracheal Intubation and Difficult Bag-Mask Ventilation Andrew Messiha, M.D., Charles Smith, M.D., Case Western Reserve University MetroHealth Medical Center, Cleveland, OH A 56-year-old male with hematuria bladder tumor and multiple medical problems was scheduled for elective cystourethroscopy and TURBT. He had a very thick beard but the airway exam was otherwise favorable. Urology requested muscle paralysis to prevent surgical difficulty from obturator contraction. After preoxygenation anesthesia was induced with midazolam propofol fentanyl and rocuronium. Bag mask ventilation was difficult due to an inadequate seal and tracheal intubation was unsuccessful (MAC 4 blade). It was then decided to proceed with placement of an LMA and mechanical ventilation. Surgery proceeded uneventfully and there were no postoperative anesthesia complications. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC999 Urgent Awake Fiberoptic Intubation in a Patient With a Rapidly Enlarging Neck Mass Andrew Messiha, M.D., Charles Smith, M.D., Case Western Reserve University MetroHealth Medical Center, Cleveland, OH A 71-year-old female with coronary artery disease atrial fibrillation and sleep apnea was admitted to the medical floor because of an acutely enlarging neck mass with odynophagia. Anesthesia was consulted for urgent tracheal intubation prior to transfer to the medical ICU. Upon evaluation it was decided she should be taken immediately to the operating room for awake fiberoptic intubation with ENT surgeons at the bedside. The airway was secured after topicalization (lidocaine) and sedation (dexmedetomidine ketamine and midazolam). The patient was subsequently found to have necrotizing fasciitis of the neck and required extensive surgeries including tracheostomy. Tuesday, October 15 10:30 AM - 12:00 PM FA MC1000 An Unnecessary and Expensive Complication: Should We Continue to Teach Landmark-Guided Techniques for Central Venous Catheter Placement to Our Residents? Merrick Miles, M.D., H David Hardman, M.D., MBA, University of North Carolina at Chapel Hill, Chapel Hill, NC A 73 kg male was scheduled to undergo aorto-bifemoral bypass surgery. After anesthetic induction the faculty anesthesiologist encouraged the anesthesiology resident to use landmark-guided techniqueseven though a ultrasound machine was readily available- to place an internal jugular catheter. Despite the presence of good anatomical landmarks and the use of a 22-gauge seeker needle the carotid artery was inadvertently punctured with a larger catheter resulting in a neck hematoma tracheal deviation and case cancellation. We will discuss whether or not we should continue to teach landmark techniques to anesthesiology residents in 2013 along with the economic costs of this complication. Tuesday, October 15 10:30 AM - 12:00 PM FA MC1001 Retrograde Intubation After Unsuccessful Tracheotomy Benjamin Miron, Student, Dan Betterly, M.D., Mitchell Lee, M.D., NYU School of Medicine/ NYU Langone Medical Center, New York, NY Pt is a 58-year-old male with metastatic thyroid cancer s/p total thyroidectomy neck dissection and irradiation presents for tracheotomy. Preop airway exam significant for Mallampati 4 limited neck ROM and mouth opening. Patient was induced for general anesthesia and intubated w/ difficulty. During tracheotomy due to abnormally calcified trachea the surgeons were unable to place tracheostomy tube. After multiple attempts surgical manipulation caused the ETT to be dislodged. Pt was temporarily ventilated via 5.5 ETT through tracheotomy hole. Patient was then successfully intubated via emergency retrograde technique using an OG via tracheotomy. Ultimately tracheotomy tube was successfully placed. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 10:30 AM - 12:00 PM FA MC1002 Hypertensive Crisis in a Burned Patient With Spinal Cord Transection Rahul Modi, M.D., Michel Kearns, M.D., Keck School of Medicine of USC, Los Angeles, CA 28-year-old man with a past medical history of T11 spinal cord transection suffered bilateral lower extremity burns (18% BSA). Three hours into debridement and grafting surgery he became extremely hypertensive. He received approximately 600mL of epinephrine 1:1000000 subcutaneously one hour prior. Hypertension was refractory to increased depth of anesthesia narcotics and intravenous nitroglycerine. Hypertension resolved with intravenous bolus dose of nicardipine. We attribute this hemodynamic response to the TelfaTM dressings soaked in 1:10000 epinephrine applied during the procedure. The differential diagnosis includes autonomic hyperreflexia in a patient with spinal cord injury. Tuesday, October 15 10:30 AM - 12:00 PM FA MC1003 Anesthetic Management In an Adult With MELAS Syndrome Undergoing Intertrochanteric ORIF Asif Mohammed, M.D., San San Lo, M.D., NYPH- Columbia University, NYC, NY A 55-year-old man with recently diagnosed Mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes (MELAS) syndrome presented for ORIF of a right intertrochanteric fracture. MELAS is a rare genetic disorder that affects multiple organ systems secondary to a defect in oxidative phosphorylation. It may result in lactic acidosis electrolyte abnormalities dysrhythmias and temperature disturbances. Our anesthesic plan was spinal anesthesia with dexmedetomidine for sedation and an arterial line for monitoring electrolytes. The patient was initially calm but became increasingly aggitated which necessitated conversion to general anesthesia with propofol induction. No post or intraoperative lactic acidosis/anion gap was noted. Tuesday, October 15 10:30 AM - 12:00 PM FA MC1004 The Unusual Treatment of Intraoperative Bronchospasm in a Patient With Severe COPD Henry Monsour, D.O., Scott Miller, M.D., Wake Forest University Baptist Medical Center, Winston Salem, NC A 59-year-old woman presented for T9 to sacrum spinal fusion due to continued lower back pain.

Tuesday, October 15 10:30 AM - 12:00 PM FA MC1006 PEA Arrest Due to a Tension Hemothorax: A Case Study Tucker Mudrick, M.D., Jonathan Wanderer, M.D., Vanderbilt University Medical Center, Nashville, TN A 63-year-old male with a history of aortic dissection s/p aortic arch repair as well as recent thoracic aortic aneurysm s/p endovascular repair presented for revision of his thoracic aortic graft. Patient's intraoperative course was complicated by celiac and superior mesenteric artery occlusions requiring bypass grafts as well as significant intraoperative blood loss and an open abdomen. Immediately postop patient went into PEA arrest secondary to a tension hemothorax. While undergoing CPR patient had return of spontaneous circulation after needle decompression was performed; chest tube was then placed. He was discharged on postoperative day 24 in excellent condition Tuesday, October 15 10:30 AM - 12:00 PM FA MC1007 Challening Anesthetic in a Patient With Neuromyelitis Optica (Devic's Disease) Fernando Mujica, M.D., John Pawlowski, M.D., Beth Israel Deaconess Medical Center, Boston, MA A 51-year-old female with Neuromyelitis Optica (NMO) chronic pain on high dose opioids and severe kyphoscoliosis presented for a right total hip replacement. Pre-operatively ultrasound was used to assist in placement of a lumbar epidural for analgesia. A video laryngoscope was used for anticipated difficult airway and the case was performed under general anesthesia with an endotracheal tube. This case will review the features associated with NMO and specific anesthetic considerations in patients affected with the disease. Tuesday, October 15 10:30 AM - 12:00 PM FA MC1008 Anesthetic Management of a Patient Undergoing Concomitant Adrenalectomy for Pheochromocytoma and Abdominal Aortic Aneurysm Repair Hani Murad, M.D., Ricardo Martinez-Ruiz, M.D., Christina Matadial, M.D., Jackson Memorial Hospital/ University of Miami/ Miller School of Medicine and Miami VA Medical Center, Miami, FL A 65-year-old man in whom the diagnosis of a 5.8 cm abdominal aortic aneurysm and 4.5cm right adrenal mass on CT scan had been made incidentally while being investigated for hematuria. A Copyright © 2013 American Society of Anesthesiologists multidisciplinary team approach was utilized to formulate a management plan. The patient was planned for concomitant resection of the pheochromocytoma and aneurysm repair. The main concern was for maintaining hemodynamic stability throughout the perioperative period. Discussion will focus on monitoring pharmacological manipulation of the patients hemodynamics as well as postoperative concerns in the intensive care unit. MCC Session Number – MCC15 Tuesday, October 15 1:00 PM - 2:30 PM FA MC1009 Cold Agglutinin Hemolytic Anemia Thomas Myers, M.D., Melody Ritter, Ochsner Medical Center, New Orleans, LA A 70-year-old male presented for percutaneous nephrolithotomy to remove a large staghorn calculus. In preoperative clinic he was found to have cold agglutinin disease and chronic lymphocytic leukemia. Management of his cold agglutinin disease involved avoidance of cold weather rituxan therapy erythropoietin and multiple blood transfusions. A plan of care was started in the preoperative clinic. On the day of surgery normothermia was maintained through a multimodal warming approach verified by measuring temperature at multiple sites. Despite an uneventful anesthetic and surgical course on post operative day number one he developed a post operative myocardial infarction. Tuesday, October 15 1:00 PM - 2:30 PM FA MC1010 Glidescope-Assisted Nasal Fiberoptic Intubation in an Unanticipated Difficult Airway Anand Nagori, New York University, New York, NY An otherwise healthy 50-year-old female was given general anesthesia for abdominal hysterectomy. Preoperative assessment revealed airway anatomy predictive of easy intubation. Patient was induced and easy to mask ventilate. Direct laryngoscopy failed to visualize vocal cords. Upon Glidescope laryngoscopy the tube could not be directed anteriorly towards the vocal cords. Fiberoptic intubation failed due to secretions and airway edema from previous laryngoscopy. Oral fiberoptic intubation with Glidescope view attempted but it was impossible to direct the scope anteriorly. Nasal fiberoptic intubation with Glidescope view was successful. Ventilation was provided between attempts at intubation. Tuesday, October 15 1:00 PM - 2:30 PM FA MC1011 Profound Vasoplegia After Albumin Administration Tran Nguyen, M.D., Sharanya Nama, M.D., Mark Hudson, M.D., University of Pittsburgh Medical Center, Pittsburgh, PA A 72-year-old male with diabetes cardiomyopathy (ejection-fraction 35%) and recurrent esophageal carcinoma who was on an ACE-inhibitor underwent a redo-esophagectomy. An arterial line and internal jugular introducer with Swan-Ganz catheter were placed prior to induction. Induction and endobronchial intubation were uneventful and surgery proceeded as planned. Albumin was administered for preoperative volume depletion. Within minutes of starting albumin the patient's blood pressure plummeted to a mean arterial pressure of 32. Hypotension was refractory to phenylephrine and Copyright © 2013 American Society of Anesthesiologists vasopressin and ultimately required epinephrine boluses with norepinephrine dopamine and dobutamine infusions. Vasoplegia resolved in 6 hours and vasoactive agents were weaned off. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1012 A Puzzling Case of Monckeberg's Arteriosclerosis: Is it Just Me or Is this Patient Persistently Hypotensive for No Apparent Reason Stacie Oliver, M.D., Pamela Roberts, M.D., William Havron, M.D., Gozde Demiralp, M.D., University of Oklahoma, Oklahoma City, OK 57-year-old female with a past medical history of diabetes hypertension right carotid endarterectomy and 40 pack-year smoking history presented to a level one trauma center after a motor vehicle collision with persistent hypotension despite fluid resuscitation. Endocrinology and cardiovascular workup did not reveal an etiology for her hypotension. After orthopedics revised a splint exposing her right arm it was found she was normotensive in her right arm after noninvasive and arterial lines in every other extremity had measured hypotension. The woman was found to have subclavian steal of the left upper extremity and Monckeberg's arteriosclerosis in her lower extremities. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1013 Life Threatening Anemia From Hemorrhage Complicated by Hyperkalemia: A Case Report Lawrence Ota, Eugene Kim, M.D., Peter Roffey, M.D., Marianna Mogos, M.D., Duraiyah Thangathurai, University of Southern California, Los Angeles, CA A 77-year-old male was admitted from clinic to the ICU for severe anemia complicated by hyperkalemia. He had Comorbidities that included DM HTN CAD and bladder ca. The patient laboratory values from clinic were significant for potassium of 6.4 mmol/L hemoglobin of 4.6 g/dL bicarbonate of 15 and Cr 4.4. Vital signs stable. Patient was admitted to the ICU. Pt was resuscitated with 5 units prbc. A Multi-modal approach was used (diuretic lasix nahco3 kayhexalate epinephrine) to correct anemia while not worsening hyperkalemia. 12 hours later the patients hemoglobin was 31. Cr decreased to 2.7. Potassium decreased to 4.0. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1014 Complete Hepatectomy as Treatment for Failed Liver Transplant Francisco Pasdar-Shirazi, Harendra Arora, University of North Carolina Hospitals, Chapel Hill, NC A 60-year-old male with end-stage liver disease underwent an uneventful liver transplantation. On POD2 ultrasound exam demonstrated diminished flow to the hepatic artery thought to be from splenic artery steal. The patient was taken to the OR for aorto-hepatic artery bypass. After initial recovery his clinical picture declined around POD 12 with marked increase in LFT's worsening coagulopathy and acidosis. Upon emergent re-exploration the intra-op pathology revealed marked liver necrosis. A total hepatectomy was performed as a rescue measure with the intention of re-transplantation. We discuss issues related to perioperative management of liver allograft failure and the anhepatic patient Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CC MC1015 Venovenous Bypass During Liver Transplantation in a Patient With Fulminant Hepatitis B Mayur Patel, M.D., Esamelden Abdelnaem, M.D., University of Arkansas for Medical Sciences, Little Rock, AR Patient was a 60-year-old Caucasian male with history of multiple myeloma who developed fulminant hepatitis secondary to hepatitis B virus one month prior to presentation. This was evidenced by worsening coagulopathy and altered mental status. Patient was also complicated by septic shock acute kidney failure hospital acquired pneumonia emphysema and dvt in right subclavian. It was decided that he was a candidate for liver transplantation. Rapid sequence induction was performed and airway was easily secured. Adequate venous and arterial access was established. During anhepatic phase of surgery venovenous bypass for hemodynamic support was used. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1016 Anesthetic Management of a Parturient in Acute Respiratory DIstress Syndrome (ARDS) Ronak Patel, Lakhmir Chawla, Katrina Hawkins, M.D., GWU, Washington D.C, DC A 36-year-old female in her third trimester of pregnancy presented to the hospital with symptoms of acute respiratory distress syndrome (ARDS). The patient had no significant medical history. Initially the patient had presented with fever and cough but subsequently developed shortness of breath. She was transferred to the intensive care unit and soon required intubation. Initial studies were inconclusive as to causation of her illness and treatment with antibiotics and anti-viral medication were not improving her clinical situation. It was determined that a semi-elective caesarean section was the most appropriate course of action for both mother and the fetus. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1017 Lung Volume Reduction Coil (LVRC) Treatment: The First Clinical Case in the United States Eric Ponte, Tetsuro Sakai, M.D., Ph.D., University of Pittsburgh School of Medicine, Pittsburgh, PA Emphysema is a common disease. Lung Volume Reduction Coil (LVRC) Treatment is a novel procedure designed to improve quality of life of patients with emphysema. During Standard bronchoscopy metal coils are inserted into emphysematous lobe to reduce lung volume through various mechanisms and improve overall lung function. Potential complications of the procedure could pneumothorax hemothorax pneumonia COPD exacerbation and mild hemoptysis. Anesthetic management should be modified to those reduce complications by reducing tidal volumes and PIP avoidance of NO2 etc. We present a case of 65-year-old female who was the first to receive this therapy in the United States. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CC MC1018 Cerebroprotective Hypothermia After Cardiopulmonary Bypass Pump Malfunction Sudheer Potru, D.O., Jackson Memorial Hospital, Miami, FL, Giri Srikanthan, M.D., University of Miami, Miami, FL 61-year-old male with history of MIx2 and CVA presented for CABG. After starting CPB and aortic crossclamp the patient was found to have low-CO state(< 1 L/min) and BIS dropped to zero. After aortic dissection and venous cannula malposition were ruled out the roller pump was exchanged but the patient continued with low flows for 45 minutes. Cerebroprotection measures were initiated with cooling to 24C; the procedure was completed. Hypothermia was continued coming off CPB and maintained in the ICU for 15 hours. Twelve hours later he returned to neurologic baseline and was extubated. There were no further complications. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1019 Adult Congenital Heart Disease - A Complicated Postoperative Course Harish Ram, M.D., Wolf Kratzert, M.D., Ph.D., University of New Mexico, Albuquerque, NM Incidence of congenital heart disease though stable in pediatrics has been growing by about 5% each year in adults. Ebstein anomaly (EA) consists of wide anatomic spectrum of abnormalities of tricuspid valve and right ventricle along with associated anomalies. Perioperative management is guided by structural abnormality present and extent to which hemodynamics compromise functional status. Arrhythmia and right ventricular failure are common and early operative mortality varies from 4% to 5.9%. We present an interesting case of a 41-year-old male with EA who underwent atrial septal defect closure with a fenestration and had a complicated post-operative course. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1020 Sevoflurane in refratory Status Asthmaticus in the ICU Setting Ashraf Resheidat, M.D., John Pennant, M.D., Paul Sheran, M.D., University of Texas Southwestern, Dallas, TX 10-year-old AAM uncontrolled asthma admitted to the PICU after 5 hr SOB wheezing.

The patient refers neurotoxoplasmosis and recent use of cocaine. The surgical team promptly decides to remove the foreign body under anesthesia as the bleeding was increasing. We decided to perform a rapid sequence of intubation using Rocuronium .The removal through the rectum was not successful and a Laparotomy had to be performed. Two hours later we used sugammadex uneventfully, showing its secure use on these patients. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1022 Dexmedetomidine Sedation and High Degree AV-Block Gabriel Rice, M.D., Yawar Qadri, M.D., Ph.D., Janakiram Ravulapati, M.D., M.P.H., University of North Carolina at Chapel Hill, Chapel Hill, NC A 68-year-old female was admitted to the ICU after an emergent laparotomy for perforated viscus. In an attempt to wean her ventilator support she was transitioned to low dose dexmedetomidine infusion for sedation. After initiation of dexmedetomidine she had episodes of hemodynamic instability with heart rates in the 30s and hypotension. The high-grade heart block ceased with discontinuation of dexmedetomidine. A 20-year-old female admitted to the ICU after extensive surgery for mandibular osteosarcoma was sedated with dexmedetomidine. She also developed AV-block at high doses of dexmedetomidine which resolved with a dose reduction. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1023 Rapidly Progressing Bullous Skin Lesions With Acute Respiratory Failure Rhabdomyolysis and Acute Kidney Injury Bradley Rodgers, M.D., Avinash Kumar, M.D., Vanderbilt University, Nashville, TN 60-year-old female with an unclear PMH presents to the ICU with a rapidly evolving bullous skin eruptions acute respiratory failure acute kidney injury rhadomyolysis after being found down and unresponsive at home. The patient had a blistering congealing rash covering 70-80% TBSA mucosal and ocular involvement and hemorrhagic conversion. She was recently diagnosed with gout. Toxic epidermal necrolysis is suspected and confirmed with biopsy. The precipitating cause was likely allopurinol. The ICU course involved IVIG therapy RRT aggressive wound care acute respiratory failure necessitating a tracheostomy. The complex presentation and comorbidities made ICU management challenging in this patient.

Abdominal CT was not diagnostic. An initial diagnosis of an acute FMF flare was made. The patient was admitted to the ICU for several days with a septic-like picture and remained there for about two weeks. She deteriorated with respiratory failure leukocytosis and sepsis. Serial abdominal CT scans were negative. She was taken for an exploratory laparotomy and found to have perforated bowel. Tuesday, October 15 1:00 PM - 2:30 PM CC MC1029 Long Term Sedation in the Pediatric Intensive Care Unit: An Unusual Reaction to Propofol Goonjan Shah, M.D., Peggy McNaull, M.D., University of North Carolina, Chapel Hill, NC An 8-year-old with a history of tracheotomy for severe subglottic stenosis presented to PICU for postoperative management of laryngotracheal reconstruction. After an uneventful surgery he was kept intubated seven days for post-surgical healing. His course was complicated by difficulty with sedation. He was trialed on various sedatives including dexmedetomidine fentanyl ativan morphine and ultimately propofol. After extubation he had dyskinesia. Of note the patient had a history of bipolar and was talking olanzapine. Anesthesia was consulted with a differential including narcotic withdrawal and reaction to propofol. This case examines a rare but distressing side effect of propofol. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1030 Push Pin Pushed Too Far Yarnell Lafortune, M.D., Branko Furst, M.D., Albany Medical Center, Albany, NY 16-year-old female presented for removal of an airway foreign body. The ENT surgeon made several attempts but the push pin migrated further into the right bronchus. A thoracic surgeon was consulted and further attempts to retrieve the foreign object failed. With every attempt there was increasing trauma and bleeding. After nearly three hours the decision was made to intubate the trachea start Copyright © 2013 American Society of Anesthesiologists steroids and continue attempts on the following day. Unfortunately attempts by an experienced bronchoscopist and two thoracic surgeons were unsuccessful. A double-lumen tube was then placed and the patient underwent a thoracotomy and segmentectomy. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1031 Intraoperative Opioid-Free Anesthesia for a 16-year-old Male With TBSA 40% Electrical Burns Using Simultaneous Intravenous Lidocaine and Dexmedetomidine Infusions Brian Lee, Agnieszka Lesicka, M.D., T. Anthony Anderson, M.D., Ph.D., Massachusetts General Hospital, Boston, MA 16-year-old male with history of electrical burn TBSA 40% involving bilateral lower extremities resulting in bilateral below knee amputations. The patient was then scheduled for a penile/perineum reconstruction with donor tissue and free flap from his thighs. Regional anesthesia was considered but not used due to the extent of the burn injury to his lower body. To minimize intraoperative opioid use a dexmedetomidine and lidocaine simultaneous infusions (never studied in the pediatric literature) with isoflurane 1% was used and upon emergence and extubation the patient was pain free alert and required no opioids in the PACU. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1032 Intraoperative Opioid-Free Anesthesia for a 19-Year-Old Male Undergoing Right Radial Forearm Free Flap to the Right Lower Extremity WIth Split Thickness Skin Graft Using Simultaneous Intravenous Lidocaine and Dexmedetomidine Infusions Brian Lee, M.D., Agnieszka Lesicka, M.D., T. Anthony Anderson, M.D., Ph.D., Massachusetts General Hospital, Boston, MA Intravenous lidocaine and dexmedetomidine infusions have been separately shown to decrease post operative pain anesthetic and opioid requirements but not studied together in the pediatric anesthesia literature. 19-year-old male with osteomyelitis of an open tibia fracture from a MVA who required a free flap coverage from the right forearm flap to the RLE with a split thickness skin graft. We used an opioid free anesthetic with simultaneous intravenous lidocaine and dexmedetomidine infusions with isoflurane 1.0% instead of regional anesthesia. Upon emergence and extubation the patient was alert pain free with no opiate requirement in the PACU. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1033 Innovative Airway Management in a Boy With Dandy Walker Syndrome John Liu, Xiaoqi Liu, M.D., Kalpana Tyagaraj, M.D., Maimonides Medical Center, Brooklyn, NY We present a 3-year-old boy with history of Dandy-Walker lissencephaly Walker-Warburg syndrome was admitted to PICU in respiratory failure for emergent intubation. After multiple unsuccessful attempts anesthesiologists were called. Direct laryngoscopy and pediatric glidescope assisted intubations were unsuccessful due to increasing secretions edema and angle of the cords. Intubating LMA and oral fiberoptic attempted intubations failed because of secretions blocking the camera. Nasal fiberoptic with aid of direct vision from Glidescope was successful in maneuvering through angled cords. Pediatric surgeon was at bedside for emergency tracheostomy backup throughout.

He presented with incarcerated inguinal hernia. Bedside reduction was unsuccessful and was scheduled for an urgent inguinal hernia repair. He was diagnosed 2 weeks prior with a viral URI with cough and orthopnea. His pacemaker was interrogated and set to DOO mode; the ICD function was turned off; and Zoll pads were placed. He underwent general endotracheal anesthesia with an ilioingunal nerve block and remifentanil for analgesia. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1035 Case of a Four-year-old With Trisomy 8 for Wilms' Tumor Resection and Pulmonary Nodule Biopsy: An Anesthetic Perspective. Jack Louro, UM/ Jackson Memorial Hospital, Miami, FL, Kimberly Kimmel, M.D., Miami Children's Hospital, Miami, FL We will discuss the case of a 4-year-old with trisomy 8 who was recently found to have a large left renal mass and pulmonary nodules. The patient had a history of multiple anomalies from his chromosomal abnormality including cleft palate hypospadias and tethered cord which had previously required surgical correction. We will discuss the anesthetic implications of Wilms' tumor resection and thoracoscopy for nodule biopsy. We will also review the anesthetic approach of a patient with previous difficult airway and cleft palate along with an overview of anesthetic concerns in patients with chromosomal abnormalities. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1036 Awake Craniotomy in a 9-year-old Matthew McDaniel, M.D., Alicia Shook, M.D., Duke University, Durham, NC A nine-year-old female presented for surgical management of intractable seizures. She underwent craniotomy for placement of strip electrodes and returned to the operating room for resection of epilepsy focus ten days later. The patient underwent a total intravenous anesthetic (TIVA) using propofol dexmedetomidine and remifentanil with an LMA while the neurosurgeon dissected down to the target area. The patient was awakened and the LMA removed for the speech mapping portion of the procedure utilizing intermittent fentanyl boluses for patient comfort. After completion of the awake portion the TIVA was resumed and the case proceeded uneventfully. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM PD MC1037 Perioperative Management of the Pediatric Patient With Shone's Syndrome During Mitral Valve Replacement With a Melody Valve Matthew Monteleone, M.D., William Schechter, M.D., Columbia University, New York, NY A 2-year-old boy with Shone's complex presented for MV replacement with a Melody valve: a stentmounted valved vein graft. The intra-operative course was notable for three bypass runs each highlighting a potential complication of this valve replacement technique. A key advantage of the Melody valve is that it is expandable and can be adjusted by balloon catheterization as the child grows. However the potential requirement for multiple bypass runs as well as disruptions to the cardiac conduction system coronary blood flow and overall cardiac function caused by a physical obstruction from the valve itself make this surgery particularly challenging. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1038 Anesthetic Management of One Lung Ventilation in a One-year-old With Diffuse Pulmonary Hemangiomas Meeta Patel, M.D., Lauren Moore, Venkata Sampathi, M.D., SUNY Upstate Medical University, Syracuse, NY Pulmonary hemangiomas are extremely rare with only a few reported cases. The anesthetic plan and management for single lung ventilation is challenging when considering various issues including but not limited to lung isolation and extubation/ postoperative care. We are presenting the case of a one-yearold that underwent open lung biopsy for recurrent upper respiratory infection fevers and thrombocytopenia. One lung ventilation was accomplished by using a fiberoptic bronchoscope and a Fogarty embolectomy catheter. The surgery proceeded uneventfully and successfully. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1039 Persistent Hypotension in a 12-year-old Male With Klippel-Feil Syndrome for Cervical Disk Fusion and Thoracic Scoliosis Correction Neelima Myneni, M.D., Scott Hines, M.D., The Children's Hospital of Philadelphia, Philadelphia, PA A 12-year-old boy from Kuwait with a history of Klippel-Feil syndrome moderate pulmonary hypertension severe restrictive lung disease secondary to kyphoscoliosis and morbid obesity underwent an occiput to T8 posterior spine fusion. Intraoperative course was significant for intractable hypotension that began immediately after prone positioning and resolved spontaneously when patient was turned supine. In this case intraoperative hypotension lead to loss of neuromuscular signals and evidence of end organ dysfunction.This case will highlight the proper preoperative evaluation of a patient with Klippel-Feil syndrome. A discussion of the physiological derangements in the prone position will be reviewed highlighting the need for proper positioning.

Airway Complications Among Two Outpatient Pediatric Patients With Mild URI Undergoing Elective Surgery Wendy Nguyen, M.D., Caron Hong, M.D., M.S., University of Maryland School of Medicine, Baltimore, MD Here we describe two cases of patients with mild URI symptoms who developed laryngospasm during anesthesia. Case 1 is a 15-month-old male with mild nasal purulence who underwent mask GA for circumcision. Succinylcholine was required on emergence to overcome severe laryngospasm. Case 2 is a 17-month-old female with resolving URI symptoms who underwent GA with ETT for gastrostomy reversal. She developed laryngospasm immediately after intubation that resolved with propofol. She also had delayed reinitiation of breaths after deep extubation requiring reintubation. Deciding whether to perform an elective procedure in similar cases may not be straightforward. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1041 Myotonic Muscular Dystrophy Type I Ngoc Nguyen-Famulare, M.D., Harshini Dani, D.O., Montefiore Medical Center, Bronx, NY Myotonic muscular dystrophy patients can present several anesthetic challenges. We intend to present a case of a 14-year-old female with history of myotonic muscular dystrophy type 1 developmental delay attention deficit-hyperactivity disorder and history of 1st degree AV block. She experienced successful management of her primary experience under general anesthesia for laparoscopic cholecystectomy. We credit this to a careful detailed discussion with the surgical team regarding use of neuromuscular blocking agents discussion with family about possible post operative ventilation careful administration of intraoperative opioids and vigilant monitoring during recovery followed by 24 hour postoperative observation. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1042 Airway Management in a Case of Morbid Obesity and Severe Obstructive Sleep Apnea With Fibrodysplasia Ossificans Progressiva Ngoc Nguyen-Famulare, M.D., Children's Hospital at Montefiore, Bronx, NY, Michael Akerman, M.D., Albert Einstein College of Medicine, Bronx, NY A 5-year-old female with fibrodysplasia ossificans progressiva (FOP) severe obstructive sleep apnea (OSA) and morbid obesity was evaluated for bilateral myringotomy and tubes (BMT) for conductive hearing loss and recurrent otitis media. She had 4+ tonsillar hypertrophy and apnea-hypopnea index of 125. Tonsillectomy was contraindicated due to risk of temporomandibular joint ankylosis. Her OSA was being treated with CPAP of 14. While mask anesthesia is typically sufficient for BMT her co-morbidities posed challenging airway management. With careful multidisciplinary perioperative consideration an Intubating Laryngeal Airway (ILA) was planned. ILA can be a primary airway or a conduit for fiberoptic intubation.

Some complications of Massive Transfusion occur more readily in children one of them being transfusion-associated hyperkalemia. This case involved an 18-month-old female with an acute subdural hematoma taken to the OR for an emergent craniotomy and hematoma evacuation. The patient developed profound hemorrhage after cerebral exposure requiring rapid massive transfusion and thereafter acutely deteriorated coded and was eventually resuscitated. The patient developed suspected life-threatening transfusion-associated hyperkalemic cardiac arrest secondary to Massive Transfusion. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1044 Anesthetic Management of Arthrogryposis and Its Related Complications Jose Otero, M.D., Shridevi Pandya Shah, M.D., UMDNJ-NJMS, Newark, NJ Arthrogryposis multiplex congenita is a syndrome involving the neuromuscular system with an incidence of 1:3000 live births. This is a case of a 3-year-old male born at term with low birth weight congenital skeletal dysplasia with arthrogryposis features of dextroscoliosis multiple joint contractures bilateral hip dislocations global developmental delay generalized hypotonia micrognathia high arched palate difficult intravenous access and tracheostomy secondary to chronic respiratory failure on home ventilator requiring high peak pressures presenting for surgical correction of bilateral severe equinus foot deformities. Muscle biopsy was done at the age of 10 months and malignant hyperthermia susceptibility was ruled out. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1045 Anaphylaxis After Ophthalmic Artery Infusion Chemotherapy Mario Patino, M.D., Todd Abruzzo, M.D., Mohamed Mahmoud, M.D., Cincinnati Children's Medical Center, Cincinnati, OH 8-year-old with relapsed retinoblastoma presented for cerebral angiogram with ophthalmic artery infusion chemotherapy of melphalan carboplatin and topotecan. 15 minutes after the infusion was started significant hypotension with generalized flushing compatible with anaphylaxis was found. Volume resuscitation epinephrine corticosteroids and transfer to the ICU were necessary. Tryptase levels at 1 and 3 hours after the beginning of the episode were significant elevated. The child recovered successfully from this episode. Postoperative evaluation by allergies found carboplatin and vecuronium as the triggers of her anaphylaxis with an allergy prick test positive for carboplatin and positive intradermal skin test for vecuronium.

He had a pre-existing gastric tube through which the endosurgical instrumentation was placed after a gastroscope was advanced from his mouth. During the case we encountered gastric insufflation profound bradycardia subglottic narrowing and a dislodged endotracheal tube. We discuss in our presentation the important anesthetic factors to consider for a SIPES Procedure as well as for children with Down Syndrome in general. SIPES is becoming more frequent and anesthesiologists need to be aware of the anesthetic implications. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1047 Anesthetic Management of an Infant With Congenital Macroglossia Todd Peacock, Wake Forest Baptist Health, Winston-Salem, NC We present the case of a male infant with congenital macroglossia secondary to lymphovenous malformation for tongue debulking procedure. The patient was delivered and intubated via EXIT procedure; however he was extubated and discharged home without the need for airway support. He returned at 6 months at which time a tracheostomy was performed prior to tongue debulking. Following inhalation induction the patient was intubated via tracheostomy. Surgery proceeded with the use of an argon laser for resection. Significant blood loss called for red blood cell transfusion; otherwise the case proceeded without incident. The patient was transported to the ICU post-operatively. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1048 Infant Found to Have Subglottic Mass on Intubation for Cardiac MRI Blake Perkins, M.D., James Priepot, M.D., Andrea Guyon, M.D., University of Illinois, Peoria, IL A 3-month-old girl with a history of inspiratory stridor for 7 weeks was found to have a subglottic mass during intubation for cardiac MRI. Previously the patient had a 2D echo performed with concern for vascular ring and was undergoing cardiac MRI for further evaluation. During induction of anesthesia a Grade 1 Cormack-Lehane view was obtained with direct laryngoscopy using a Miller 1 blade. However a 3.0 cuffed endotracheal tube was unable to be passed due to a subglottic obstruction. The obstruction was later found to be a subglottic hemangioma and the patient was started on propranolol for treatment. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1049 Anesthetic Management of a Subglottic Mass in a Pediatric Patient Liem Pham, University of Michigan Health System, Ann Arbor, MI RK is a 10-week-old healthy female infant who presented with inspiratory stridor. Flexible nasal laryngoscope exam was performed by ENT in the ED and showed a normal larynx with a subglottic mass. She was taken to the OR for flexible bronchoscopy and biopsy of the mass. She was induced by mask Copyright © 2013 American Society of Anesthesiologists with sevoflurane and nitrous oxide and IV access was obtained. Her anesthesia was maintained with a propofol infusion and ketamine during the DL/Bronch. She maintained spontaneous respiration throughout with adequate oxygenation. Her subglottic mass was visualized and diagnosed as a hemangioma. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1050 Surviving Ectopia Cordis Bretonya Phillips, M.D., John H. Stroger Hospital of Cook County, Chicago, IL, Chike Gwam, M.D., Advocate Christ Hospital, Chicago, IL 3-year-old female w/ intrauterine diagnosis of ectopia cordis was born term delivery via c-section. Pt underwent multiple staged cardiac procedures including repair of tetrology of fallot multiple ventricular septal defects and double outlet right ventricle. The patients final surgical procedure was complicated by an unexpected early closure of the tracheostomy stoma postop day one requiring a second operation to revise the tracheostomy. This unexpected morbidity requiring pt. to have to undergo a second surgery questions how compromised the immunological response/healing properties are in patients with conditions in which so much of the cardiovascular system is dysfunctional. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1051 Saturation Versus. Peak Airway Pressure Case Report of Pleuropulmonary Blastoma Bretonya Phillips, M.D., John H. Stroger Hospital of Cook County, Chicago, IL, Nnaneme Mgbodille, M.D., Advocate Christ Hospital, Chicago, IL 2-year-old male previously presented w. upper respiratory symptoms w/ diagnosis of pneumonia. After two weeks of antibiotics w. no resolution of symptoms pt. began having shortness of breath and subsequently underwent a VATS for working diagnosis of plueral effusion w/ empyema. VATS procedure w/minimal effusion and negative empyema. Two months later pt. presented w. significant shortness of breath and acute respiratory distress requiring emergent intubation. Subsequent CT of chest found 12*14cm heterogenous mass in right hemithorax compressing pulmonary artery trachea and heart. Pt emergently underwent debulking procedure successfully removing ninety percent of tumor. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1052 Urgent Management of Congenital Cystic Adenomatoid Malformation in a Neonate Cooper Phillips, M.D., Ashraf Farag, M.D., Brian McClure, D.O., Texas Tech University Health Sciences Center, Lubbock, TX A term infant with congenital cystic adenomatoid malformation was delivered via cesarean section with respiratory distress which resulted in intubation and mechanical ventilation. Further deterioration of respiratory status necessitated urgent resection of the lesion. Shortly after entering the operating room breath sounds on the left side became diminished and then absent. After proper endotracheal tube placement was confirmed a preliminary diagnosis of spontaneous pneumothorax was made. Further expansion of the pneumothorax compromised surgical exposure ventilation and hemodynamics requiring conversion to open thoracotamy. The malformation was successfully removed without further complications. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM PD MC1053 A Neonate With Unsuspected Grade IV Laryngeal Cleft Joyce Phillips, M.D., Sally Vender, M.D., University of New Mexico, Albuquerque, NM A 37-week newborn developed feeding problems which included cough and difficulty swallowing. Barium swallow revealed massive aspiration with a diagnosis of a large H-type tracheo-esophageal fistula. In the OR inhalation induction was uneventful. Rigid bronchoscopy identified a proximal fistula. Laryngoscopy appeared normal. Intubation was accomplished without problem. Following incision there appeared to be a massive leak and end tidal CO2 was lost. Subsequent bronchoscopy revealed a large vestibule from the larynx to the carina. Case discussion will compare and contrast the embryology clinical presentation evaluation and management of a newborn with a tracheoesophageal fistula vs. a laryngeal cleft. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1054 TEE as a Monitor of Intraoperative Ventricular Volume and Function and IV Fluid Management: The Impact of TEE on Pre-Intra and Postoperative Management in the Partial Separation of Conjoined Twins Claire Rezba, M.D., Iolanda Russo-Menna, M.D., Virginia Commonwealth University, Richmond, VA Thoracoabdominal conjoined twins presented for partial separation after worsening hemodynamic and respiratory compromise. They had a large volume shunt causing high output cardiac failure in BG2 and hypotension and oliguria in BG1. Their unique anatomy and shared systems required innovative imaging to optimize their preoperative intraoperative and postoperative course. In this case study an intracardiac echocardiogram probe was utilized as a transesophageal echocardiogram for preoperative evaluation as well as for intraoperative fluid management and cardiac monitoring during the partial separation of conjoined infants. Tuesday, October 15 1:00 PM - 2:30 PM PD MC1055 Foreign Body Removal at Rt. Main Bronchus in a Neonate Patient Hyunsu Ri, Sangwook Shin, Seunghoon Baek, Jiyoung Yoon, Eunjung Kim, Pusan National University Yangsan Hospital, Yangsan, Republic of Korea Foreign body in the airway could be a life-threatening risk especially to pediatric patients. A 6 day old neonate with foreign body which was located deep in the rt. main bronchus was admitted. Although we tried three times to remove it with rigid bronchoscope and forcep we failed. Before switching to surgical treatment we decided to move the foreign body near to the forcep. The position became trendelenburg and we tapped the back several times. Finally we caught it. We suggest that back percussion with trendelenburg position is an useful solution to remove a foreign body in a deep airway.

The case was challenging due to the presence of a mediastinal mass (the hematoma) with resultant tracheal compression and difficulty in achieving adequate ventilation. The unique challenges to ventilation that are posed by tracheal compression the tools that were used to definitively diagnose tracheal compression and the ultimate treatment of the tracheal compression caused by the hematoma will all be discussed in the case presentation. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1057 Autonomic Dysfunction After Combined Epicardial and Endocardial Atrial Fibrillation Ablation Procedure Jay Schoenherr, M.D., Lavinia Kolarczyk, M.D., UNC Hospital, Chapel Hill, NC A 57-year-old male with a history of non-ischemic cardiomyopathy and paroxysmal atrial fibrillation presented for combined epicardial and endocardial atrial fibrillation ablation. Epicardial ablation was performed via a right sided thoracotomy incision followed by a traditional endocardial ablation technique. The patient developed hypotension one hour into the endocardial portion requiring a phenylephrine infusion. He emerged from general anesthesia uneventfully but his pressor requirement remained elevated. Attempts to wean phenylephrine were unsuccessful. After ruling out hypovolemia and ongoing blood loss transient autonomic dysfunction from inadvertent autonomic fiber ablation was suspected. Dopamine was initiated and was weaned within 24 hours. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1058 Anesthetic Management of a Sickle Cell Trait Patient Requiring Thoracoabdominal Aortic Aneurysm Repair With Possible Hypothermic Circulatory Arrest Joshua Sebranek, M.D., Richard Wolman, M.D., Martha Wynn, M.D., University of Wisconsin School of Medicine and Public Health, Madison, WI A 61-year-old male with sickle cell trait presented for Crawford type II thoracoabdominal aortic aneurysm repair with possible cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). Preoperative hemoglobin was 12.0 g/dL hemoglobin A1 55.6% (reference range 94.3-98.5%) and hemoglobin S 40.1% (0%). On the day prior to surgery the patient underwent an exchange transfusion with 12 units of packed red blood cells. The aneurysm was repaired without CPB or DHCA. The patient's temperature reached a minimum of 31.7 degrees Celsius. He had an uneventful postoperative course and was discharged home on postoperative day six.

Post-procedure echo showed the severity of mitral stenosis had decreased but worsening right ventricular systolic pressure mitral regurgitation and tricuspid regurgitation and a new interatrial shunt. Patient returned at 34+5 weeks in preterm labor and underwent cesarean section. She received 5L fluid intraoperatively and developed pulmonary HTN and edema. She was reintubated and transferred to the CCU. After successful diuresis Patient was extubated and discharged from the hospital with plans to follow up for possible future mitral valve replacement. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1060 Hemi-Arthroplasty Under Continuous Spinal in a 94-year-old With NSTEMI 3 Days Prior Anna Shapiro, M.D., Randolph Hastings, M.D., University of California San Diego, San Diego, CA A 94-year-old deaf man presented for left hemi-arthroplasty after a fall. On admission he was diagnosed with a NSTEMI which was managed conservatively. After arterial line placement in the pre-operative area he was brought to the operating room where a continuous spinal catheter was placed at the L4/L5 interspace. He was given 2cc 0.5% bupivacaine and 2mg tetracaine resulting in a T6 sensory level. His operative and post-operative courses were uneventful. This case illustrates the successful use of continuous spinal anesthesia in a patient with a recent NSTEMI. The details of management will be presented and discussed. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1061 Management of Post Operative Hypoxemia in Patient With Uncontrolled Pulmonary Hypertension. Nathaniel Sharp, M.D., Amanda Gomes, M.D., Oklahoma University Health Science University, Oklahoma City, OK A noncompliant 26-year-old F with congenital pulmonary artery stenosis resulting in severe pulmonary hypertension mean PA pressure of >85 required an emergent cholecystectomy. After an uneventful induction and stable intraoperative course she was extubated after meeting extubation criteria but quickly became hypoxic and agitated. We avoided re-intubation with interventions including sedation analgesia mask ventilation inhaled iloprost and IV magnesium. She was transported to ICU with CPAP and discharged the following day without further complications. Our case demonstrates the anesthetic management in response to the pathophysiology of severe pulmonary hypertension and unanticipated post-extubation hypoxia. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CA MC1062 Endovascular Stent Grafting Under Regional Anesthesia in a Patient With A History of Heparin Induced Thrombocytopenia Mourad Shehebar, M.D., Andrew Leibowitz, M.D., Icahn School of Medicine Mount Sinai, New York, NY Endovascular stent graft repair (ESGR) of abdominal aortic aneurysms have become increasingly common. Patients undergoing this procedure require anticoagulation intraoperatively which is usually accomplished with unfractionated heparin. Patients with a history of HIT must be anticoagulated with an alternative agent. A 80-year-old male with CAD HTN COPD and a history of HIT presented with a 8.3 cm infrarenal AAA for an elective ESGR. Bivalirudin has been approved for use in PCIs but has never been reported specifically in patients with HIT undergoing ESGR. We have demonstrated the successful use of bivalirudin for anticoagulation in this case. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1063 Persistent Hypotension During Cardiopulmonary Bypass in a 51-year-old Woman Undergoing Mitral Valve Repair Timothy Sims, M.D., Peter Neuburger, M.D., NYU Medical Center, New York, NY A 51-year-old woman who is otherwise healthy is scheduled to undergo mitral valve repair secondary to severe mitral regurgitation. After an unremarkable induction and early operative course the patient became acutely hypotensive at the initiation of cardiopulmonary bypass. Blood pressure was confirmed by measurement at aortic root and poor perfusion was suspected with a peak lactate of 4.0mg/dl. The hypotension was minimally responsive to vasoactive agents methylene blue transfusion and an increased bypass flow rate however the blood pressure normalized immediately upon separation from cardiopulmonary bypass. Vasoactive infusions were discontinued and the patient had an unremarkable postoperative course. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1064 Coronary Artery Bypass Grafting in a Patient With Severe Hypothyroidism Maninder Singh, M.D., Jonathan Hastie, M.D., Columbia University Medical Center, New York, NY Our case involves a 53-year-old female with severe hypothyroidism (HT) who presented to the ER with an NSTEMI. Workup revealed TSH 142 mIU/L. TTE demonstrated EF of 45% with a large pericardial effusion. Levothyroxine was initiated and after two weeks she underwent CABG surgery at a TSH level of 78mIU/L. Upon anesthetic induction the patient developed hypotension and PEA arrest and was resuscitated after 4 minutes of ACLS. CABG was preformed and CPB weaned using IABP. We will discuss the pathophysiology of myocardial depression in severe HT and associated factors leading to premature atherosclerosis in this disease group. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CA MC1065 Acquired Von Willebrand Syndrome and Cardiac Surgery Mark Smith, M.D., David Barbara, M.D., William Mauermann, M.D., Mayo Clinic, Rochester, MN A 77-year-old female with chronic anemia and aortic stenosis presented for aortic valve replacement. Preoperative hematologic workup revealed acquired von Willebrand syndrome (AvWS). No specific treatment for AvWS was required intraoperatively. Surgery was performed uneventfully without significant perioperative bleeding. AvWS is a rare disorder associated with various cardiac conditions including aortic stenosis. Despite normal levels of von Willebrand factor (vWF) AvWS patients have a deficiency of the more active high molecular weight vWF multimers. Treatments must be individualized and are divided into those that increase vWF levels and modalities that reduce depletion of high molecular weight vWF multimers. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1066 Perioperative Management of Pulmonary Embolectomy Pingping Song, Rosemary Uzomba, M.D., Michael D'Ambra, M.D., Brigham and Women's Hospital, Boston, MA 42-year-old male presented to the operating room with saddle pulmonary embolus for pulmonary embolectomy. Radial arterial and central venous catheters were placed without sedation while patient remained fully awake and breathing spontaneously. After patient was prepped and draped for sternotomy anesthesia was induced with midazolam sufentanil succinylcholine and epinephrine bolus. Cardiopulmonary bypass (CPB) was rapidly established and pulmonary embolectomy was completed uneventfully. Patient was weaned off CPB and taken to ICU on inhaled epoprostenol as well as intravenous epinephrine milrinone and vasopressin. ICU discharge occurred on postoperative day (POD) 8 and patient was discharged home on POD11. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1067 Rhabdomyolysis (RML) Associated Acute Kidney Injury (AKI ) After Coronary Artery Bypass Grafting (CABG) Suraj Sudarsanan, M.D., Heart Hospital Hamad Medical Corporation, Doha, Qatar Prolonged surgery due to difficult coronary grafting lead to Rhabdomyolysis induced AKI in a 55 years old male patient. Peak Creatinine kinase and Myoglobin levels were 39000 IU/ml 40000ng/ml respectively. Patient developed heart failure which along with AKI and supervening sepsis lead to prolonged ICU stay and hospitalization. The patient's renal function recovered over 4 weeks aided by Renal replacement therapy in the form of hemodialysis Early recognition of Rhabdomyolysis induced AKI in prolonged surgery is important in reducing the post-operative morbidity and mortality. Key words: Acute kidney injury (AKI) Rhabdomyolysis Coronary artery bypasses graft Prolonged surgery. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CA MC1068 Diagnosis of a Type 1 Aortic Dissection by Intraoperative TEE: A Case Report and Discussion Jessica Sumski, M.D., George Washington University Medical Center, Washington, DC, Travis Weddington, M.D., Washington Hospital Center, Washington, DC A 60-year-old male presented with an intraaortic balloon pump for a 2 vessel off pump CABG. A TEE was placed after bruising was noted on the aorta. Using the TEE we were able to diagnose a Type I circumferential aortic dissection involving the root and valve that resulted in significant AI. The dissection was previously unidentified prior to the TEE by the Anesthesiology team. The case proceeded with an on-pump type I dissection and valve repair with circulatory arrest. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1069 Anesthetic Management in an Adult Patient With Double-Chambered Right Ventricle and Severe Obesity Takahiro Tadokoro, Hisae Higa, Tetsuya Kawabata, Kouji Yoza, M.D., Okinawa Prefectural Nanbu Medical Center & Children's Medical Center, Shimajiri-gun Okinawa, Japan, Manabu Kakinohana, M.D., Kazuhiro Sugahara, M.D., University of the Ryukyus, Nishihara-cho Okinawa, Japan We experienced an anesthetic management of an adult obese patient undergoing repair of doublechambered right ventricle.This patient was preoperatively complained of dyspnea chest pain and tachycardia following light exercise. After anesthetic induction as soon as manual ventilation with high positive airway pressure started blood pressure rapidly decreased. Thus intermittent iv phenylephrine and fluid loading were performed against hypotension. In this case high airway pressure might reduce cardiac preload resulting in augmentation of right intraventricular stenosis causing hypotension. Therefore we should be aware that adequate cardiac preload may be crucial for stabilizing hemodynamics in patients with double-chambered right ventricle. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1070 Von Willebrand's Disease in the Setting of Aortic Stenosis: Acquired Disease? Incidental Diagnosis? Barbara Meinecke, M.D., Susan Taylor, M.D., Children's Hosp. of Wisconsin, Medical College of Wisconsin, Milwaukee, WI A fifteen-year-old male presented for elective resection of a subaortic membrane and aortic valve repair/replacement. Significant history included ventricular septal defect and subarotic stenosis repaired in infancy as well as sickle cell trait. Personal and family histories were negative for bleeding events. Preoperative hematology consultation revealed prolonged PT PTT reduced factors X XI and VWF consistent with abnormal platelet function. Similar results were reported in 2009 at which time MRI demonstrated significant acceleration of flow across the aortic valve annulus. Hematology interpretation of the findings was von Willebrand's Type 1 disease and consequently recommended DDAVP preoperatively. Surgery proceeded without incident. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CA MC1071 Incidental Finding of Severe Mitral Regurgitation in a Patient Undergoing Aortic Arch Aneurysm in a Prior Heart Transplanted Patient Michael Tran, D.O., Eduardo Jusino Montes, M.D., Brian Johnson, M.D., Cleveland Clinic Foundation, Cleveland, OH 77-year-old male with PMHx of HTN HLD CABG x4 in 1999 s/p heart transplant in 2000 for ICM CKD hypothyroidism and gout was presented with complaints of intermittent sub-sternal chest pain. CXR demonstrated mediastinal widening and a CT chest w/o contrast revealed a saccular thoracic aortic aneurysm measuring up to 7 cm in transverse diameter. The aneurysm involves the ascending aorta and aortic arch terminating at the level of the left subclavian artery. After induction of anesthesia and upon TEE examination we incidentally found out that the patient has severe mitral regurgitation prompting a change to the surgical approach. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1072 TEE Diagnosis of Right-to-Left Shunt Through a Patent Foramen Ovale in a Patient With a Renal Tumor Invading the Right Atrium Dam-Thuy Truong, M.D., Dilip Thakar, M.D., Angela Truong, M.D., University of Texas MD Anderson Cancer Center, Houston, TX A 53-year-old male with a renal mass invading the IVC and right atrium presented for nephrectomy and thrombectomy. TEE was performed for continuous intraoperative monitoring. A patent foramen ovale (PFO) with left-to-right shunt was detected. During surgical manipulation of the heart sudden severe desaturation occurred. A new right-to-left shunt through the PFO was diagnosed. After the atrial thrombus was removed right atrial pressure decreased and the flow through the PFO returned to a leftto-right shunt with resolution of hypoxemia. TEE in this case allowed for an instantaneous diagnosis of reversal of shunt and ruled out other potential causes of desaturation. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1073 Treatment of Severe Mitral Regurgitation Following Transcatheter Aortic-Valve Implantation: A Case Report Laura Tunke, M.D., Jafer Ali, M.D., Case Western Reserve University/University Hospitals Case Medical Center, Cleveland, OH Transcatheter aortic-valve implantation (TAVI) is an innovative procedure for patients with severe aortic stenosis that are not candidates for surgical replacement. Our patient is an 88-year-old male with severe aortic stenosis mild mitral regurgitation (MR) and systolic heart failure status post pacemaker implant who underwent a TAVI procedure and developed severe MR post-implantation evidenced on TEE. After the pacing swan was discontinued and intrinsic pacer activity resumed severe MR resolved and mild MR consistent with pre-TAVI TEE was demonstrated. This is an uncommon complication of TAVI procedures and resumption of an intrinsic pacemaker is a simple effective intervention. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 1:00 PM - 2:30 PM CA MC1074 Orthopedic Surgery Prior to Cardiac Surgery in a Patient With Obstructive Left Atrial Myxoma Eleanor Vega, M.D., Edward Kahl, M.D., Oregon Health and Science University, Portland, OR 52-year-old with history of pre-syncope presented with a hip fracture after a fall. Transthoracic echocardiogram revealed a left atrial myxoma obstructing the mitral valve during diastole. Patient required both myxoma resection and fixation of hip fracture but which should occur first? Cardiac team felt the risk of morbidity after cardiac surgery in a non-ambulatory patient was higher than potential myxoma-related complications during the orthopedic procedure. Patient underwent intramedullary nail placement under spinal anesthesia followed by atrial myxoma resection one week later. There are very few case reports in the literature describing non-cardiac surgery in the setting of atrial myxoma. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1075 An Uncommon Indication for TAVI Marc Vives, M.D., Ph.D., Erik Horlick, M.D., Mark Osten, M.D., Massimiliano Meineri, M.D., Toronto General Hospital, Toronto, ON A 47-year-old female presented with acute rejection and refractory cardiogenic shock after a heart transplant for idiopathic cardiomyopathy. Given a LVEF of 20%. an Impella device was inserted the antirejection regimen readjusted and plasmapheresis started. The LV function fully recovered in a week but likely as a result of mechanical damage the patient developed severe aortic insufficiency. TAVI was considered a viable option. Prior to TAVI a left femoral-femoral A-V ECMO for hemodynamic rescue was electively inserted. A Corevalve was successfully deploied without rapid ventricular pacing though a percutaneous femoral approach. The patient was discharged home two weeks later. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1076 Flash Pulmonary Edema During Management of Evolving Myocardial Ischemia Matthew Waldron, M.D., Yong Peng, M.D., University of Florida, Gainesville, FL A 65-year-old male presented with acute coronary syndrome. He had emergent left heart catheterization and found to have severe 3- vessel coronary artery disease not amendable to stenting. His LVEDP was elevated at 39 mmHg and as intra-aortic balloon pump (IABP) was placed for improving coronary perfusion. The patient quickly developed respiratory insufficiency. He subsequently was intubated and a large amount of pink frothy liquid was expelled from the endotracheal tube. Echocardiography then revealed severe aortic insufficiency. This case highlights the importance utilization of (IABP) for coronary perfusion and the subsequent development of pulmonary edema. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1077 Intraoperative Management of a Tracheo-Innominate Fistula Andrea Westman, M.D., Annemarie Thompson, M.D., Vanderbilt University, Nashville, TN 71-year-old with radiation-treated thyroid cancer as an adolescent and chronic radiation vasculitis and laryngitis requiring recent tracheostomy presented with hemoptysis. On admission the patient sustained a sudden 1.5 L hemorrhage from his tracheal stoma. Imaging studies were nondiagnostic but a high Copyright © 2013 American Society of Anesthesiologists clinical suspicion for tracheoinnominate fistula remained. After consideration of both surgical and nonsurgical options the patient underwent successful repair of the TI fistula and ligation of the innominate artery after a right axillary-femoral artery bypass was performed. Despite establishment of an alternate cerebral circulation the patient suffered a left-sided stroke but was eventually discharged from the hospital. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1078 Cardiac Herniation After Repair of Penetrating Trauma Raj Singh, M.D., Anna Weyand, M.D., John Porter, M.D., Sloan Youngblood, M.D., Baylor College of Medicine, Houston, TX 25-year-old male presented with hemopericardium after penetrating trauma to the chest. Eleven hours after initial repair of a small right ventricular puncture wound during which he required multiple episodes of cardioversion oxygen saturation acutely dropped into the 50s. Bedside TTE revealed a grossly dilated right atrium and right ventricle with severely depressed ventricular function and noncompressible IVC. Emergent exploration on cardiopulmonary bypass revealed cardiac herniation through the pericardium with kinking of the pulmonary artery on the edge of the trauma-induced pericardial defect. Dissection of the atria revealed an acquired secundum atrial septal defect with a torn membrane. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1079 Anesthetic Implications of Extended Right Hepatectomy in a Patient With Fontan Physiology: A Case Report Paul Weyker, M.D., Christopher Webb, M.D., Tricia Brentjens, M.D., Taylor Johnston, M.D., Columbia University, New York, NY Patients who have undergone complete caval-pulmonary anastomosis-the Fontan procedure-have direct passive venous blood flow from the superior and inferior vena cava into the pulmonary circulation without passing through the morphologic right ventricle. Although this procedure has been shown to be an effective means of palliation for these patients chronic elevated central venous pressure lead to several types of hepatic dysfunction including chronic passive congestion cardiac cirrhosis and even hepatocellular carcinoma. This is the first case report of a patient with Fontan associated hepatocellular carcinoma who successfully underwent a right hepatectomy for curative therapy. Tuesday, October 15 1:00 PM - 2:30 PM CA MC1080 Perioperative Considerations for Left Ventricular Assist Devices in the Pediatric Population: A Case of Fulminant Myocarditis Secondary to Influenza A Jordan Wicker, Cesar Rodriguez-Diaz, M.D., Icahn School of Medicine at Mount Sinai, New York, NY The patient was a 2-year-old male with influenza A developing acute myocarditis. Significant objective findings included fever refractory hypotension TEE revealing severe left ventricular dysfunction and positive troponins. The patient required cardiopulmonary resuscitation and was sustained on increasing doses of inotropic and vasopressor agents. The patient was brought to the OR for ventricular assist device (VAD) placement to optimize hemodynamics with eventual decannulation and discharge home. This case reviews perioperative management of pediatric patients with acute heart failure and Copyright © 2013 American Society of Anesthesiologists exemplifies VAD use in this population as a means to hasten and permit recovery rather than bridge to cardiac transplant. MCC Session Number – MCC16 Tuesday, October 15 3:00 PM - 4:30 PM CA MC1081 Intraoperative Emergency Veno-Venous ECMO Application Via Avalon Cannula for PostCardiopulmonary Bypass Hypoxemia in an Infective Endocarditis Patient Melanie Witte, M.D., Oksana Klimkina, M.D., The University of Kentucky, Lexington, KY A 17-year-old male with a history of intravenous drug abuse presented with headache and fever. He was diagnosed with infective endocarditis severe aortic and mitral insufficiency. The patient became septic and developed ARDS. He emergently underwent replacement of mitral and aortic valves but postcardiopulmonary bypass couldn't maintain oxygenation despite normal cardiac function. ECMO was instituted via the Avalon cannula placed in the internal jugular vein. Placement of the cannula was guided by fluoroscopy and transesophageal echocardiography. Within 48 hours the patient's oxygenation improved and he no longer required ECMO. The patient was discharged from the hospital within six weeks. Tuesday, October 15 3:00 PM - 4:30 PM CA MC1082 Eptifibatide as Bridging Anti-Platelet Therapy Prior to Lumbar Cerebro-Spinal Fluid Drainage (LCFD) Hak Wong, M.B.

Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM CA MC1084 Anesthetic Management of an Adult Wiith Surgically Corrected Hypoplastic Right Heart Syndrome. Nicholas Lam, M.D., Steven Wright, M.D., University of New Mexico, Albuquerque, NM A 29-year-old male with a history of hypoplastic right heart syndrome presented with a symptomatic incisional hernia and was scheduled for repair. The patient had a complicated congenital heart history with several palliative procedures including aortopulmonary shunt Glenn procedure and Fontan procedure. Goals for the anesthetic included maintaining systemic vascular resistance and preload while augmenting heart contractility and avoiding fluid overload. General anesthesia was induced with etomidate and the patient was kept ventilating spontaneously with a laryngeal mask airway. Inotropy was increased with small boluses of epinephrine. The procedure was completed without difficulty and no anesthetic complications were observed. Tuesday, October 15 3:00 PM - 4:30 PM CA MC1085 Anesthetic Management of a Patient With LVAD for Wrist Debridement Boris Yaguda, M.D., Giuseppe Trunfio, M.D., Maimonides Medical Center, Brooklyn, NY 73-year-old male with existing LVAD on anticoagulation presented for left wrist debridement secondary to septic arthritis. Patient's main concern was adequacy post op pain control. The decision was made to proceed with ultrasound guided left axillary block for postoperative pain management and general anesthesia via LMA. Case is being presented for discussion of use of LVAD as destination therapy and successful management of regional anesthesia in the presence of anticoagulation. At the end of the case right IJ TLC was placed under US guidance for IV access and patient was successfully extubated with good pain control. Tuesday, October 15 3:00 PM - 4:30 PM CA MC1086 Peripartum Cardiomyopathy in a Laboring Parturient John Gantamasso, M.D., Jason Yu, M.D., Kalpana Tyagaraj, M.D., Maimonides Medical Center, Brooklyn, NY We describe a case of a 29 years G5P2 Nigerian female at 40 weeks with a history significant for recent fever and cough who presented for induction of labor. Shortly after arrival labor analgesia was initiated with CSE and the patient was comfortable over the next several hours. As labor progressed the patient developed acute shortness of breath progressively worsening hemoptysis hypoxia and ensuing fetal bradycardia. An emergent C-Section was performed with supportive management of symptoms consistent with flash pulmonary edema. Further work up by cardiology and obstetrics revealed the diagnosis of peripartum cardiomyopathy. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM CA MC1087 Sudden Hemodynamic Instability in a Patient With Undiagnosed Systolic Anterior Motion of the Mitral Valve John Zaki, Adeel Qaisar, Texas Tech University Health Science Center, El Paso, TX Patient came in for a elective back surgery. Upon induction patient became hemodynamically unstable. On examination it was noted patient had crackles in the chest and a new systolic mumor. EKG showed early repolarization. Patient was stabilized and patient was transfered to ICU. Subsequent echo showed dydtolic anterior motion of the mitral valve. Tuesday, October 15 3:00 PM - 4:30 PM CA MC1088 Complex Central Venous Cannulation Due to Unusual Bilateral Non-Thrombotic IJV Architecture Suzana Zorca, M.D., Bijal Patel, M.D., Denise Hersey, M.A., Gerard McCloskey, M.D., Yale-New Haven Hospital, New Haven, CT A 62-year-old gentleman with chronic atrial fibrillation on pradaxa systemic hypertension and severe mitral and tricuspid regurgitation presented for Mitral and Tricuspid Valve repair. After smooth induction of general anesthesia the patient was placed in Trendelenburg position for internal jugular vein (IJV) cannulation. Ultrasound imaging of the right IJV revealed a valvular flap vs.possible preexisting vein dissection. Contralateral scanning of the left IJV revealed a similar anomaly. Fluoroscopy was helpful in assessing and cannulating the left-sided IJV and placing a Swan-Ganz catheter over a Cordis. We review the literature on non-thrombotic IJV anomalies and their implication for central venous cannulation. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1089 Paroxysmal Nocturnal Hemoglobinuria Under General Anesthesia: Avoiding Hemolysis Sean Summers, M.D., Shivon Abdullah, M.D., Gozde Demiralp, M.D., Lyle Stefanich, M.D., OUHSC, Oklahoma City, OK Paroxysmal nocturnal hemoglobinuria (PNH) is a rare form of hemolytic anemia. We report a 73-yearold female with PNH presenting for laparoscopic cholecystectomy and highlight the importance of preoperative evaluation and planning to promote a safe operative course. The coordination of efforts between anesthesiology general surgery and hematology provided a brief hospital stay free of exacerbation of her condition and a favorable outcome for this patient. Patients with PNH are at risk of aplastic anemia thrombosis and acute intravascular hemolysis. The risk of hemolysis is increased by metabolic derangements produced by surgery and general anesthesia. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1090 Challenging Airway Management for Removal of Foreign Body From the Trachea Jonathan Tan, M.D., M.P.H., Slawomir (Peter) Oleszak, M.D., Christopher Tam, M.D., Renata Kowal, M.D., Stony Brook University School of Medicine, Stony Brook, NY 59-year-old male with difficult appearing airway presented for removal of foreign body located proximal to the carina. After induction the patient had easy mask ventilation and multiple failed attempts at rigid Copyright © 2013 American Society of Anesthesiologists bronchoscopy. Despite laryngoscopy cricoid manipulation and changes in patient position rigid bronchoscopy was unable to be placed. Patient was then intubated with a tube exchanger using a Jackson laryngoscope. Fiberoptic flexible bronchoscope was placed in the left nare. The rigid bronchoscope was placed over the tube exchanger and guided into the trachea with direct visualization from the fiber optic bronchoscope. The object was removed successfully. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1091 Sleeve Resection of a Left Main Bronchial Mass Via Right Thoracotomy. The Challenge of One Lung Ventilation. Minyi Tan, M.D., New York Presbyterian, New York, NY, Tehmina Akhtar, M.D., Alessia Pedoto, M.D., Memorial Sloan Kettering Cancer Center, New York, NY A healthy 36-year-old nonsmoker female (84kg 163cm) with a 1.7x1.1 cm left mainstem mass presented to the OR for a sleeve resection via right thoracotomy. Left lobar ventilation and perfusion were decreased in the setting of obstructive lung disease. When the right lung was collapsed there was difficulty in maintaining oxygenation despite changes in the ventilator parameters the use of CPAP and jet ventilation beyond the lesion. The case was performed by ventilating the non-dependent lung which was partially compressed by the surgeon. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1092 Facial Trauma and Difficult Airway Management Jonathan Teets, M.D., New York University, New York, NY 88-year-old male pedestrian struck by bicycle presented with acute C3 vertebral body fracture and LeFort I II and III facial fractures. Transtracheal and bilateral superior laryngeal nerve blocks were completed in addition to topicalization of oropharynx with local anesthetic. Two unsuccessful attempts at awake fiberoptic intubation revealed extensive bloody secretions and airway edema so the team proceeded with awake tracheotomy. This case focuses on difficult airway management in facial trauma patients with discussion of specific types of facial trauma that may precipitate the need for surgical airway access. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1093 An Unusual Cause of Intraoperative ST Segment Changes Brian Telesz, M.D., Xun Zhu, M.D., Mayo Clinic, Rochester, MN A 74-year-old female with PMH significant for renal cell carcinoma is scheduled for a lung wedge resection due to metastasis. Previous echocardiogram showed no regional wall motion abnormalities. Anesthetic induction was uncomplicated. Upon lateral decubitus positioning ST segment depressions were noted and persisted despite adequate hemodynamic and HR control; the procedure was cancelled. Troponins returned negative and ECG showed resolving ST segment depressions. Coronary angiography showed no significant obstruction but did show hypervascular lesions near the coronary sinus. Cardiac MRI confirmed renal cell carcinoma metastasis which might have impacted coronary blood flow upon left lateral positioning intraoperatively. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM FA MC1094 Anesthetic Management For A Patient With Haw-River Syndrome Eric Tesoriero, D.O., Brian Kornrumpf, M.D., Kelly Baird, M.D., Wake Forest Baptist Health, Winston Salem, NC 46-year-old female with past medical history significant for Haw-River Syndrome (Dentato-RubroPallido-Luysian Atrophy) and seizure disorder presents with strangulated umbilical hernia. She was posted for an emergent hernia exploration and reduction. She underwent RSI with propofol and succinylcholine. Despite a MAC of 1.3 with full return of neuromuscular relaxation from succinylcholine the surgeons reported difficulty reducing hernia defect and requested neuromuscular blockade. At the conclusion of the case with full reversal she had no signs of neuromuscular weakness and was extubated without difficulty. The remainder of her perioperative course was unremarkable for seizure activity or other events. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1095 Awake Intubation Using Video Laryngoscopy in the Extremely Difficult Airway Neel Thomas, M.D., Peter Rivera, M.D., Wake Forest Baptist Health, Winston-Salem, NC A Level 1 agricultural trauma patient was brought to WFUBMC after a devastating tractor injury resulted in the avulsion of his maxillary segment and midface. Though bleeding profusely without identifiable airway landmarks the patient maintained a patent airway in the lateral position. The patient and surgical team were brought to the OR where SLN and trans-tracheal airway blocks were performed and topical anesthesia administered to the oropharynx. Fiberoptic intubation was unsuccessful due to bloody secretions and distorted tissue planes obstructing view. A C-MAC was used to carefully expose the glottis allowing an ETT to be passed through the vocal cords. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1096 Pushing the Boundaries of the Laryngeal Mask Airway and Your Comfort Zone in Order to Avoid Unnecessary Awake Fiberoptic Intubation Nicholas Tinkham, M.D., M.P.H., H. David Hardman, M.D., MBA, University of North Carolina at Chapel Hill, Chapel Hill, NC A 63-year-old male with a prior gunshot wound to his neck and subsequent formation of a massive keloid measuring 14cm X 8cm on his anterior neck was scheduled for surgical resection of his neck mass. He was in no apparent respiratory distress but his airway exam demonstrated limited mouth opening. A recent clinic fiberoptic laryngoscopy exam documented normal airway anatomy. Although he had recently undergone awake fiberoptic intubation for a prostatectomy the anesthesia team elected to place a laryngeal mask airway (LMA) for this procedure. We will discuss the pros and cons of utilizing a LMA in this setting. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM FA MC1097 Transtracheal Jet Ventilation: More Than Just Rescue Ventilation Sheel Todd, M.D., Jessica Booth, M.D., Wake Forest Baptist Health, Winston Salem, NC A 62-year-old male with morbid obesity (BMI 46.5) Mallampati IV with a large tongue a short and thick neck OSA and diabetes presented for a whipple procedure for pancreatic cyst. Despite factors predicting a difficult airway he had a prior history of successful two hand ventilation and intubation so we chose to attempt intubation after induction of general anesthesia. Adequate ventilation through facemask was easily established. After multiple unsuccessful intubation attempts with 3 different modalities and multiple providers transtracheal jet ventilation with an 18g angiocath was used to aid in obtaining a view with a flexible fiberoptic bronchoscope. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1098 Management of Post Intubation Distal Tracheal Stenosis Stephanie Tran, M.D., Mahammad Hussain, M.D., Roy Soham, M.D., Elton Lambert, M.D., University of Texas Health Science Center, Houston, TX Case of a 34-year-old ASA 4 female who experienced life threatening long segment tracheal stenosis down to the level of the carina after an emergent endotracheal intubation. For four days after extubation she experienced dyspnea and stridor that was unresponsive to pharmacologic therapy. After the diagnosis was made she presented to our institution in respiratory distress and an emergent tracheostomy was successfully placed with ECMO lines in place in case of failure. She experienced a prolonged hospital course and because of the recurrence of stenosis there is no foreseeable decannulation. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1099 Perioperative Airway Management in a Patient With Difficult Airway and Bilateral Vocal Cord Paralysis for Laparoscopic Cholecystectomy Dam-Thuy Truong, M.D., Dilip Thakar, M.D., Angela Truong, M.D., University of Texas MD Anderson Cancer Center, Houston, TX A 61-year-old man with bilateral vocal cord paralysis known difficult airway diabetes and severe GERD presented for laparoscopic cholecystectomy. He had a MP class 4 airway with a 2 mm maximal glottic opening on laryngostroboscopy. Perioperative implications included risks for pulmonary aspiration intubating laryngeal trauma and vocal cords edema. An awake nasal fiberoptic intubation with a second fiberscope inserted through the contralateral naris was performed to visualize the atraumatic passage of the tracheal tube through the narrowed glottis. Dexamethasone racemic epinephrine and high humidity oxygen were used to minimize postop laryngeal edema which may cause complete airway obstruction. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM FA MC1100 A Technically Simple and Effective Nasal CPAP Mask for a Morbidly Obese Patient With Obstructive Sleep Apnea Under Propofol Sedation/Local Anesthesia for Irrigation and Debridement of Bilateral Posterior Calf Ulcers James Tse, M.D., Ph.D., Rose Alloteh, M.D., Trishna Upadhyay, M.D., Sylviana Barsoum, M.D., Shaul Cohen, M.D., UMDNJ-Robert Wood Johnson Medical School, New Brunswick, NJ A 71-year-old male was scheduled for irrigation/debridement of bilateral posterior calf ulcer under MAC. He had atrial fibrillation CAD hypertension obesity (BMI 45 kg/m2) and OSA. He couldn't tolerate facial CPAP because of claustrophobia. After pre-oxygenation using a TSE Mask he received deep propofol sedation (50 mg bolus and 125-75 mcg/kg/min infusion). Nasal cannula was then replaced with a makeshift nasal CPAP mask using an infant mask. Pop-off valve was adjusted to deliver CPAP of 5 cm H2O with 5-7 L O2/min and 2 L air/min. He maintained spontaneous respiration and 99-100% O2 saturation throughout with FiO2 of 0.8. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1101 Diagnosis of Aortic Thrombosis After Pelvic Surgery Kenneth Tseng, M.D., M.P.H., Christina Jeng, M.D., The Mount Sinai Hospital, New York, NY A 62-year-old gentleman was diagnosed with an acute aortic thrombus in the recovery room after undergoing an abdominal perineal resection for repair of a recto-urethral fistula. Although uncommon post-operative aortic thrombus can be a devastating complication if not recognized early. Pre-operative clinical characteristics that may predispose patients to thrombosis include hypercoagulability from neoplastic disease dehydration from bowel prep or cigarette use. Intraoperatively prolonged lithotomy positioning duration of surgery or hypoperfusion of the legs may increase the likelihood of thrombus formation. In our case all of these factors were present which raised the clinical suspicion of a thrombotic event. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1102 Anesthetic Management in a Patient With Bilateral Diaphragmatic Paralysis Kosta Turchaninov, M.D., Daniel Johnson, M.D., University of Nebraska Medical Center, Omaha, NE We describe the anesthetic management of a 63-year-old male with bilateral diaphragmatic paralysis secondary to cervical stenosis and brachial plexopathy who presented for anterior cervical discectomy and fusion. This case highlights the importance of knowledge of the pathophysiology of diaphragmatic dysfunction in the formulation of a successful anesthetic plan to prevent perioperative complications. BiPAP in the sitting position was used for pre-oxygenation induction emergence and extubation to optimize respiratory mechanics. TIVA with short-acting titratable anesthetic agents proved to be safe and adequate for this patient with bilateral diaphragmatic paralysis. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM FA MC1103 Failed Airway Management During Induction for Difficult Case of Subglottic Stenosis. Kim Vidhani, FANZCA, Anton Booth, FANZCA, Princess Alexandra Hospital, Brisbane, Australia A 40-year-old man with subglottic stenosis presented for balloon dilatation. He had exertional stridor weighed 135kg and had other difficult airway features. A spontaneous breathing TIVA induction was complicated by regurgitation laryngospasm inadequate ventilation and significant hypoxia. Administration of suxamethonium facilitated bag mask ventilation and rapid re-oxygenation. Intubation was attempted but no ETT could be passed beyond the stenosis. An inflated MLT 5 cuff was pressed onto the glottis which allowed adequate ventilation oxygenation and airway protection. Surgery proceeded and successful dilatations were facilitated by periodic removal of the MLT. Extubation was difficult but the patient recovered uneventfully. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1104 Intraoperative Tension Pneumothorax During an Intramedullary Nail Placement Jay Vyas, M.D., Michael Bassett, M.D., MetroHealth Medical Center/Case Western Reserve University, Cleveland, OH 45-year-old female was admitted for femoral nailing secondary to trauma with no other known injuries. Positive medical history of HTN asthma. NKDA. ETOH was elevated. RSI performed with fentanyl propofol and succinylcholine. Maintenance with sevoflurane. Shortly after the surgical start acute hypotension hypoxia hypocapnea and tachycardia requiring hemodynamic support developed. Left hemithorax breath sounds were absent. Bronchoscopy revealed no significant findings. A tension pneumothorax was suspected and needle decompression was performed. Hemodynamics oxygenation and ventilation improved. A chest tube was placed. For the remainder of the case the patient remained relatively stable. She was extubated and recovered without complications. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1105 When the Rubber Bag Turns to Rock: A Case of Intraoperative Bronchospasm During Parathyroid Surgery Ammar Wahood, M.D., Brian McAlary, M.D., Joel Biala, M.D., Arvind Rajagopal, M.D., Rush University Medical Center, Chicago, IL A 60-year-old non-smoking male with HIV undergoing parathyroidectomy for primary hyperparathyroidism developed severe bronchospasm after removal of his hyperplastic parathyroid gland. When manual ventilation failed his airway-irritating ETT was removed and bag mask ventilation attempted. Four forceful breaths plus sevoflurane eased bag-mask ventilation. Following rocuronium (50mg) administration topicalization of the vocal cords and larynx and reoxygenation he was successfully re-intubated. With albuterol (3 puffs) and decadron (8mg) administered his wheezing improved and his anesthesia was uneventfully maintained with sevoflurane and remifentanil. At extubation his total calcium was 5.9. Postoperatively upon further questioning he confirmed recent symptoms of respiratory infection. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM FA MC1106 Anesthetic Management of an Adolescent With a Mitochondrial Disease: Complex V Mutation Charles Walcutt, M.D., Seth Keiser, M.D., Corey Zetterman, M.D., Terry Huang, M.D., Steven Lisco, M.D., University of Nebraska Medical Center, Omaha, NE Common anesthetic practices and medications may exacerbate the symptoms of mitochondrial disorders or precipitate new problems. We present three cases involving a 14-year-old female with a mutation of Complex V of the respiratory chain causing severe gastrointestinal hypomotility. Several commonly used anesthetic agents (e.g. propofol) are relatively contraindicated in mitochondrial disorders as they inhibit complexes involved in oxidative phosphorylation. In this case the patient's care was made especially challenging due to documented adverse reactions to benzodiazepines and etomidate. Inhaled inductions were used for two intra-abdominal surgeries while remifentanil and dexmedetomidine infusions were used for an endoscopic procedure. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1107 Intracardiac Thrombus Development During Orthotopic Liver Transplantation Sara Walls, M.D., Ram Pai, M.B. B.S., Vanderbilt University Medical Center, Nashville, TN A 70-year-old female with cryptogenic cirrhosis from autoimmune hepatitis presented for orthotopic liver transplantation. The patient underwent uneventful induction of anesthesia and liver resection. Anhepatic phase was initially complicated by right pneumothorax which was promptly treated. While anhepatic the patient developed hemodynamic instability with cardiac arrest suggestive of an embolic event. Transesophageal echo revealed massive intracardiac and pulmonary artery thrombus. Chest compressions and maximal medical management ensued with brief clearance of the thrombus. Clot reaccumulated and a second arrest occurred. Tissue Plasminogen Activator was administered in a last attempt to clear thrombus. The patient expired intraoperatively. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1108 How to Diffuse A Ticking Bomb: Management of Carcinoid Crisis Christina Wang, M.D., Baylor College of Medicine, Houston, TX, Binh Higley, M.D., VA Medical Center Houston, Houston, TX The patient is a 62-year-old Caucasian male with history significant for symptomatic metastatic carcinoid tumor diagnosed in 2007 HTN HLD DMII OSA and long-standing smoking history who was undergoing exploratory laparotomy for resection of a primary mesenteric carcinoid tumor. He had two episodes of intraoperative crises one during tumor manipulation and another after tumor removal. In this case we describe the signs and symptoms of carcinoid crisis how our patient was managed during these crises and how intraoperative use of epinephrine and other sympathomimetic vasopressors concurrently with octreotide is an acceptable and effective method of management. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM FA MC1109 Membranous Tracheal Rupture During Zenker's Diverticulum Repair Derrick Wansom, M.D., Vijaykumar Tarnal, M.D., University of Michigan, Ann Arbor, MI Postintubation tracheal rupture is an uncommon complication but is associated with high morbidity and mortality. In this case report a 61-year-old female's Zenker's diverticulum repair was complicated by tracheal rupture. After uncomplicated tracheal intubation the surgeon perforated the esophagus with the rigid esophagoscope necessitating external repair. A tracheal tear of the posterior portion of the trachea was noted when the neck was explored by the surgeon. The cause of the tracheal rupture in this case is unclear. The posterior membranous wall of the trachea lacks cartilaginous support making it susceptible to tearing or rupture by mechanical causes. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1110 Management of Acute Respiratory Distress in a Patient With Acquired Tracheal Stenosis Michael Wassef, M.D., David Kramer, M.D., St. Luke's-Roosevelt Hospital Center, New York, NY The patient a 35-year-old male with IDDM and recent admission for DKA and respiratory failure requiring intubation. Anesthesiology evaluated him for acute shortness of breath and emergent intubation. Review of the CT revealed high-grade tracheal stenosis. He was managed with Heliox and instructed to practice pursed-lip breathing prior to ENT evaluation and transfer to OR. In OR he underwent mask induction with Sevoflurane and was maintained with Remifentanil infusion. Rigid laryngoscopy was performed by the surgeon and oxygenation was provided by low-frequency manual jet ventilation at 30 psi via Sander's injector. He was extubated uneventfully after tracheal dilation. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1111 Massive Hemoptysis Caused by Arteriovenous Malformation. Timothy Webb, M.D., Jiwon Lee, M.D., Brian Egan, M.D., Jerry Young, M.D., Indiana University, Indianapolis, IN A 15-year-old previously healthy female presented to the ED for worsening hemoptysis with tachypnea and hypoxemia. CT imaging revealed a right lower lobe bronchial mass. To facilitate lung isolation a leftsided double lumen tube was emergently placed using direct laryngoscopy. Bronchoscopy revealed a pulsating mass in the right bronchus intermedius. The patient underwent right middle and lower lobectomy. The mass proved to be an arteriovenous malformation. This case illustrates isolation and protection of the unaffected lung is a priority in patients with massive hemoptysis. Our report discusses options for lung isolation and protection and anesthetic management in hemoptysis patients. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1112 Anesthetic Management of a Patient With Airway-Threatening Ameloblastoma of the Jaw and Severe Anemia Mary West, Ranjit Deshpande, M.D., Yale University School of Medicine, New Haven, CT A 28-year-old Creole-speaking woman flew directly from Haiti to our hospital for treatment of a large jaw tumor (17.8 x 13.5 x 12.8 cm). It had consumed her jaw and mandible and rendered her short of Copyright © 2013 American Society of Anesthesiologists breath and unable to lie flat or speak normally. She arrived without an anesthetic preoperative evaluation or labs but it was not feasible to delay the operation which required three surgical services. We planned an awake fiberoptic intubation which was made even more difficult by our patient's anxiety. Intraoperatively we encountered additional challenges with vascular access and unexpectedly severe anemia.

Tuesday, October 15 3:00 PM - 4:30 PM FA MC1123 Anesthetic Management for an Attempted Resection of a Thoracic Pheochromocytoma in a 49-yearold Male Caleb Zelenietz, M.D., Andrea Petropolis, M.D., University of Manitoba, Winnipeg, MB We describe the presentation of a 49-year-old male presenting for resection of a mediastinal pheochromocytoma. The patient had been diagnosed several months previously during work up for headache. He was appropriately medically optimized with alpha blockade. Pre-operative imaging was not suggestive of invasion into mediastinal structures and he had no symptoms of vascular or tracheobronchial compression. The patient underwent combined thoracic epidural and general anesthesia along with one lung ventilation. Intra-operatively the mass was deemed unresectable due to pericardial invasion and significant vasularity. The operation was aborted and the patient is now awaiting cardiac surgery consultation. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1124 Repeat Liver Transplant Complicated by Massive Hemorrhage Cardiac Arrest and Undiagnosed PFO After Tetralogy of Fallot Repair Jeron Zerillo, M.D., Andrew Perez, M.D., Alan Sim, M.D., The Mount Sinai Hospital, New York, NY 45-year-old M w/hx of Tetralogy of Fallot repair HCV cirrhosis hepatorenal syndrome RBBB paroxysmal SVT and RV dysfunction presented for liver retransplantation. Preinduction aline was followed by RSI central line PAC and TEE placement. TEE demonstrated an undiagnosed PFO and allowed cardiac monitoring. Following incision significant hemorrhage ensued and massive transfusion was initiated. Despite resuscitation the patient became hypovolemic and VT arrest was successfully managed with 2 rounds of epinephrine and defibrillation. Venovenous bypass was utilized during the anhepatic phase and patient successfully underwent OLT. He was extubated off CVVH and pressors and out of the ICU by POD 5. Tuesday, October 15 3:00 PM - 4:30 PM FA MC1125 Fixation Error: Common Things are Common Sophy Zheng, M.D., BobbieJean Sweitzer, M.D., University of Chicago, Chicago, IL 29-year-old with metastatic papillary thyroid cancer hypocalcemia and hydronephrosis requiring frequent ureteral stents developed 2 cardiac arrests after MAC inductions for stent changes. Acute refractory hypotension began within 2-5 minutes then PEA arrest requiring CPR and epinephrine. Intraoperative TEE revealed profound hypovolemia but no cardiac abnormalities. Labs were relatively normal. On several previous anesthetics there was a pattern of increasing hypotension after induction. After detailed review of many records the arrests occurred 2-5 minutes following cefazolin but no arrests without antibiotics. Interesting the patient tolerated cefazolin 2 years prior but developed increasing hypotension with subsequent dosing.

An epidural ICP monitor was placed to assist in management of the increased intracranial pressure and the patient was being cooled at the time that he presented to the operating room for liver transplantation. Severe intracranial hypertension was noted throughout the intraoperative period and was exacerbated by rewarming. After completion of the case the patient developed an epidural hematoma with herniation and returned to the OR for a craniotomy. The patient recovered and was discharged with complete neurologic recovery and excellent graft function. Tuesday, October 15 3:00 PM - 4:30 PM PD MC1134 Postoperative Fever: When Do You Suspect Malignant Hyperthermia? Jesus Rubio, M.D., Sanjay Bhananker, M.D., University of Washington, Seattle, WA 8-month-old female underwent nasolacrimal duct probing with stent placement. Sevoflurane anesthesia via LMA was administered with supplemental Morphine IV. Initial PACU vital signs were unremarkable however 2 hours post-operatively the patient's heart rate and temperature were noted to be 200 and 41.2 respectively. Examination demonstrated skin mottling and jerking movements. Initial VBG demonstrated pH of 7.19. Crystalloid boluses were given and expert consultation was received. Dantrolene was prepared pending evidence of hypermetabolism. Myoglobin CK electrolytes and CBC all within normal limits. ABG analysis demonstrated pH 7.40 and lactate of 0.9. Patient admitted to PICU for observation and remained stable. Tuesday, October 15 3:00 PM - 4:30 PM PD MC1135 Selective Bilateral Bronchial Intubation in a Pediatric Patient With Tracheal Rupture Maria Sanchez, M.D., Miguel Marrero, M.D., Elisa Quintero, M.D., Carlos Ocasio, M.D., University of Puerto Rico School of Medicine, San Juan, PR We report the case of a 9-year-old female who suffered a gunshot wound to the chest resulting in tracheal rupture with ongoing air-leak and difficult ventilation. An attempt was made to initially bypass the defect with a single lumen cuffed endotracheal tube and subsequently with a left double lumen tube. Both strategies proved to be ineffective. The patient was ultimately managed with bilateral bronchial intubation using fabricated extra-long tubes. Two 4.5 mm ID ETT's were used to construct each tube resulting in adequate length and stability. Air-leak ceased and the patient received long-term ventilatory support with an uneventful recovery. Copyright © 2013 American Society of Anesthesiologists Tuesday, October 15 3:00 PM - 4:30 PM PD MC1136 Bronchoscopy Following a Peanut Aspiration in a Child With a Possible Full Stomach Natalie Maida, D.O., Donald Schwartz, M.D., Baystate Medical Center, Springfield, MA A 3-year-old female presented for bronchoscopy after a suspected peanut aspiration. She was not NPO but because of significant desaturations the procedure was not delayed. Rapid sequence induction with endotracheal intubation was performed after which her stomach was suctioned. Rigid bronchoscopy revealed a tracheal bronchus but no foreign body. Flexible bronchoscopy through an LMA noted food material obstructing the left bronchus which was eventually removed. We discuss management issues related to pediatric foreign body aspiration including induction (inhalation versus IV) ventilation (spontaneous versus controlled) foreign body location and significance of a tracheal bronchus. Bronchoscopic images accompany the discussion. Tuesday, October 15 3:00 PM - 4:30 PM PD MC1137 Anesthetic Challenges in a Patient With Methyl Malonic Acidemia Bunty Shah, M.D., Priti Dalal, M.D., F.R.C.A, Eugene Raggi, Penn State Milton S. Hershey Medical Center, Hershey, PA Methylmalonic acidemia (MMA) is an inherited disorder characterized by an inability to metabolize organic acid catabolic. Acute elevations in organic acid may occur during the perioperative period posing a challenge to the anesthesiologist. We present a case of a 14-year-old female patient with a history of MMA who presented for surgery. The period of fasting was minimized as the patient had a jejunal tube. Nitrous oxide was avoided and dextrose containing intravenous fluid was administered intraoperatively. Frequent monitoring of blood glucose levels was performed. The patient made an uneventful recovery and was discharged to home.

First a 3-year-old male with recurrent tonsillitis OSA and RAD presented for tonsillectomy adenoidectomy and myringotomy tubes placement. The intraoperative course was unremarkable but post operative course was complicated by severe laryngospasm oxygen desaturation re-intubation and transfer to PICU for further management. Second a 12 month old male with recurrent emesis presented for esophagogastroduodenoscopy. Intraoperative course was complicated by laryngospasm with oxygen desaturation followed by endotracheal intubation with pink frothy secretions. The procedure continued without further complication but patient was transferred to PICU for postoperative management. Tuesday, October 15 3:00 PM - 4:30 PM PD MC1140 Difficult Airway in a Pediatric Patient With Smith-Lemli-Opitz Syndrome for Hernia Surgery Alexander Sinofsky, M.D., NYU Langone, New York, NY A 6-year-old male with Smith-Lemli-Opitz syndrome (SLOS) presented for an umbilical hernia repair. SLOS is a metabolic congential disorder of cholesterol synthesis that results in craniofacial dysmorphism cleft palate growth retardation and intellectual disability. Given this patient's prominent microcephaly and micrognathia an extensive plan for airway management was developed prior to the start of anesthesia. The patient was easily mask ventilated but multiple attempts at intubation using direct laryngoscopy glidescope and fiberoptic failed. A laryngeal mask airway was used to ventilate the patient and the hernia repair was completed without complications.
