Administration of Solumedrol per standing orders 2. For renal graft function, Dopamine (1-4 mcg/kg/min) and Vasopressin (0.5 u/hr) as per standard orders Use these guidelines4 after other causes are ruled out (pg. 6). For donors already on pressors, initiate T4 protocol and aggressively wean pressors keeping MAP ≥ 60 or ≥ 70 mmHg with history of HTN. Use of pressors in order of importance (A-E). Consult for use of inotropes (F&G) for poor cardiac function. HYPOTENSION PHARMACOLOGICAL MANAGEMENT T4 is the first pharmacological choice (prior to pressors or inotropes) for the treatment of the hypotensive donor. *** Do NOT wean T4 until other pressors have been weaned.*** Drug Start Max Comments & Precautions A T4 (Levothyroxine) 10 mcg/hr 30 mcg/hr B Vasopressin 0.6 u/hr 5 u/hr C Dopamine 5 mcg/kg/min 30 mcg/kg/min D Levophed 5 mcg/min 30 mcg/min E Neosynephrine 10 mcg/min 300 mcg/min F Dobutamine 5 mcg/Kg/min 30 mcg/Kg/min G Milrinone 0.25 mcg/kg/min 1 mcg/kg/min - Ensure K levels are corrected - Monitor U/O if < 0.5ml/kg/hr consider “D” or “E” for alpha support Start “D” if: - HR increases 30 bpm above baseline or - >120 bpm for 1 hr or - if drip exceeds 15 mcg/kg/min Start “E” if: - HR increases 20 bpm above baseline or - >130 bpm for 1 hr or - if drip exceeds 15 mcg/kg/min - Start if HR > 130 bpm for 1 hr and vasopressin contraindicated - Consult with cardiology prior to use - consider for CVP > 15 mmHg and poor cardiac function - may cause tachycardia and hypotension 4 (dePerrot et al., 2004; Institute for Healthcare Improvement [IHI], n.d.; Rostron et al., 2008; Shemie et al., 2006; Wood, Becker, McCartney, D’Alessandro, & Coursin, 2004; Wood & McCartney, 2007) 7 Hypertension Definition MAP > 110 mmHg Hypertension Pharmacological Management5 HYPERTENSION PHARMACOLOGICAL MANAGEMENT If the donor is hypertensive the following steps should be followed: Ensure donor is not fluid overloaded (CVP > 15 mmHg, see Pulmonary Edema, pg. 23) then → wean vasopressors → inotropes → T4 → treat BP. If the donor’s HR > 120 bpm, consider option Ι & ΙΙ.

Ensure hemodynamic stability and monitor vital signs at bedside during either procedure. b. Ensure euvolemia and do not use with donors on more than one of the following pressors and doses: i. Dopamine > 10mcg/kg/min; Neosynephrine > 60mcg/min; Levophed > 10mcg/kg/min c. Stop for hemodynamic instability and/or a decrease in SpO2. d. Use caution in donors with pneumothorax/pneumomediastinum or with airleak in chest-tube: 1) Normalize pH/PaCO2 and oxygenate with FiO2 100% for 30 mins. 2) Draw baseline ABG. 3) Perform manual CPT and suction (pg. 19). 4) Change mode to CPAP with PEEP at 30 cmH2O and hold for 30 seconds. 5) Providing donor still stable, resume ventilation on prior settings with FiO2 100% and change to PEEP 10 cmH2O for 2 mins. 6) Change mode to CPAP with PEEP 30 cmH2O and hold for 30 seconds as in ‘step 4’. 7) Providing donor still stable, resume ventilation on prior settings with FiO 2 100% and change to PEEP 10 cmH2O for 1 hr. 8) Decrease PEEP to 5 cmH2O and obtain ABG 30 mins after change. 9) Decrease FiO2 to 40% and obtain ABG 30 mins after change. 10) Repeat Pulmonary Recruitment Maneuver every 12 hrs and PRN. (algorithm on page 22) PEEP Maneuver PEEP Maneuver – Place on PEEP 10 cmH2O for 1 hr, if Pulmonary Recruitment Maneuver contraindicated. 20 21 Lung Conditions Respiratory Acidosis & Respiratory Alkalosis Respiratory Acidosis Respiratory Alkalosis pH <7.3 with PaCO2 >45 mmHg For continued acidosis after ventilator adjustments, contact OTL pH >7.5 with PaCO2 <35 mmHg For continued alkalosis after ventilator adjustments, contact OTL Adjust minute volume ventilation to maintain PaCO2 35-45 mmHg → Adjust rate → Ensure Vt 8 – 10 ml/kg/PBW and PIP <35 cmH2O and Plateau Pressure <30 cmH2O Atelectasis Atelectasis18 is the collapse of the airspaces which also results in the visual impression of increased soft tissue density. This makes it impossible to distinguish infiltrates from atelectasis on the basis of visual density alone. Considering other factors is therefore required. Atelectasis must have volume loss by definition (collapse of airspaces must reduce lung volume), whereas infiltrate does not. 1. In cases with persistent atelectasis by CXR consider Pulmonary Recruitment Maneuver (pg. 20 ). 2. Prevent interruptions in the ventilator circuit when possible. a. Pulmonary Recruitment Maneuver contraindicated perform PEEP Maneuver (pg. 20) 3. Consider repeat bronchoscopy in cases of segmental atelectasis. 4. Ensure Vt 8-10 ml/kg PBW. Pulmonary Infiltrates An infiltrate19 is the filling of airspaces with fluid (pulmonary edema), inflammatory exudates (white cells or pus, protein and immunological substances), or cells (malignant cells, red cells or hemorrhage) that fill a region of lung and increase the visual impression of increased soft tissue density. 1. 2. 3. 4. 5. 6. 7. 8. 18 19 Ensure early bronchoscopy. Ensure heated humidification of vent circuit. Ensure ETT cuff inflated to 30 cmH2O. Perform Manual CPT every 2 hrs (pg. 19). Consider aggressive pharmacologic interventions for CVP >15 mmHg to treat pulmonary edema (pg. 23). Review culture & sensitivities, antibiotics, and drug regimes. Ensure HOB 30-40°. Position “good” lung down. a. Consider lateral decubitus (Powner, Darby, & Kellum, n.d.; Wood & McCartney, 2007; http://www.aic.cuhk.edu.hk/web8/Very%20BASIC%20CXR%20lungs.htm ) (Powner, Darby, & Kellum, n.d.; Wood & McCartney, 2007; http://www.aic.cuhk.edu.hk/web8/Very%20BASIC%20CXR%20lungs.htm ) 22 Pleural Effusions A pleural effusion20 is an accumulation of fluid between the layers of tissue that line the lungs and chest cavity. 1. Diagnostic portable ultrasound of chest. 2. Obtain Intensivist consult. a. If moderate to large, request placement of chest tube as needed. Pulmonary Edema Pulmonary edema21 is transudate fluid collecting in the lung tissue. Three mechanisms lead to pulmonary edema including: 1. Increased hydrostatic gradient 2. Decreased intravascular oncotic pressure 3. Increased capillary permeability due to endothelial injury secondary to herniation process and cytokine release PULMONARY EDEMA MANAGEMENT Treat the noncardiogenic pulmonary edemic donor that is fluid overloaded (CVP >15) as indicated below Ensure maintenance IV-fluids are per management guidelines (pg. 11) If donor is not fluid overloaded and maintenance IV-fluids are per guidelines, then request Cardiac consult for cardiogenic pulmonary edema as evidenced by portable CXR, refractory hypoxemia, frothy sputum and EF <30%. Medications to Consider for Pulmonary Edema Caused by Non-Cardiogenic Factors Cause Drug Dose Route Frequency & Other Fluid overload (CVP >15 mmHg) Lasix 20-60 mg IV May repeat as necessary Mannitol 25-50 gms IV May repeat as necessary Narcan 8 mg IV Every 12 hrs as needed Morphine 10 mg Bolus 12.5-25 mcg IVP; Titrate 5-10 mcg/min q 5-10 min 25% in 50 ml IV May repeat as necessary Titrate to MAP >60 or >70 mmHg with history of HTN; Max dose = 500 mcg/min May repeat every 4 hrs as needed. Follow Albumin dose with Lasix (as above) Nitroglycerin Decreased oncotic pressure Albumin (& Lasix as above) 20 IV drip IVPB (http://www.umm.edu/ency/article/000086.htm) (Baumann, Augibert, McDonnell, & Mertes, 2007; Rostron et al., 2008; http://www.mayoclinic.com/health/pulmonary-edema/DS00412/DSECTION=treatments-and-drugs; http://emedicine.medscape.com/article/300813-treatment; http://www.rxmed.com/b.main/b2.pharmaceutical/b2.1.monographs/CPS-%20Monographs/CPS-%20(General%20Monographs%20D)/DOBUTREX.html) 21 23 Liver Biopsy Management Guideline Indications and Preparation • The need for a liver biopsy22 will be determined by the OTL • Evaluate pathologist availability • Review CXR, INR and/or other requested labs with performing physician • If biopsy is being done always place sample in 0.9% NaCl Considerations • Coagulation support o Plt infusion if • Plt count is < 100,000, or • there was a history of ASA, NSAIDs, Plavix or other anticoagulants within 5 days of biopsy o FFP infusion if INR > 1.4 Potential Complications • Bleeding • Hypotension • Pneumothorax • Injury to surrounding organs Post Biopsy Care • STAT CXR & liver ultrasound with readings • Monitoring vital signs every 15 min for 1 hr and every 30 mins for 1 hr • Position on right side • Check H&H 30 mins after, then every 1 hr for 2 hrs 22 (California Pacific Medical Center [CPMC], 2003) 24 Insulin Therapy If patient has BG > 140 mg/dL address potassium imbalances as needed, and start insulin drip. If the hospital has a protocol you may use the hospital’s otherwise use the following drip protocol. Target BG levels: 80 – 110 mg/dL The insulin drip should be maintained through organ allocation as necessary in order to treat hyperglycemia. All blood glucose measurements should be performed with arterial blood samples. Initial Insulin Guide Baseline BG Bolus Initial Infusion Rate 141-160 -- 5 units/hr 161-180 2 units and 6 units/hr 181-200 3 units and 8 units/hr 201-250 5 units and 10 units/hr 251-300 5 units and 15 units/hr >300 10 units and 15 units/hr Check BG 30 minutes after beginning insulin drip and follow titration guidelines. Insulin Titration Guide BG Bolus Titration <60 Give ½ amp D50. Stop infusion. Recheck BG in 15 min. 60-80 -- Stop infusion. Check BG in 15 min. 80-110 -- by 1 unit/hr if > 50mg/dL lower than last test by 2 units/hr if > 100mg/dL lower than last test 111-120 -- No intervention 121-140 -- by 1 units/hr 141-160 -- by 2 units/hr 161-180 2 units by 2 units/hr 181-200 2 units by 4 units/hr 201-250 4 units by 5 units/hr 251-300 5 units by 5 units/hr >300 5 units by 5 units/hr Check BG 30 minutes after insulin titration. If BG >140 mEq/L repeat above titration steps. If BG within goal maintain rate, then check BG every hour. If three consecutive values within target range, then check BG every 2 hrs. After BG level is > 120 following ‘stop infusion’ restart insulin drip at ½ the previous rate 25 Insulin Titration Algorithm 26 References Angel, L. F., Levine, D. J., Restrepo, M.
