EBOLA: PERIOPERATIVE CONSIDERATIONS CLINICAL ISSUES AHEAD OF PRINT CLINICAL ISSUES Editor’s note: The following is an excerpt from the “Clinical Issues” column appearing online ahead of print. The complete column will be published in the January 2015 issue of the AORN Journal. © AORN, Inc, 2014 Pr es s Ebola Hemorrhagic Fever: Precautions in the OR QUESTION: What precautions should the perioperative team take in the OR when caring for a patient in with known or suspected Ebola hemorrhagic fever (HF)? ANSWER: le Perioperative team members should take standard, contact, droplet, and airborne precautions ic when caring for a patient with known or suspected Ebola HF in the OR. Based on the Centers for rt Disease Control and Prevention (CDC) Infection Prevention and Control Recommendations for A Hospitalized Patients with Known or Suspected Ebola Hemorrhagic Fever in US Hospitals,1 standard, contact, and droplet precautions should be taken for patients with known or suspected Ebola HF. However, when an aerosol-generating procedure (eg, bilevel positive airway pressure [BiPAP]®), bronchoscopy, sputum induction, intubation and extubation, open suctioning of airways) is performed on a patient with Ebola HF, airborne precautions also should be taken. This includes the use of an airborne infection isolation room and respiratory protection that is at least as protective as a National Institute for Occupational Safety and Health (NIOSH)-certified, fit-tested N95 filtering face piece respirator.1 Airborne precautions are necessary in the OR Page 1 of 8 EBOLA: PERIOPERATIVE CONSIDERATIONS CLINICAL ISSUES AHEAD OF PRINT because most invasive procedures involve an element of airway management, and an aerosolgenerating procedure is highly likely to occur.1 AORN’s “Recommended practices for prevention of transmissible infections in the perioperative practice setting”2 provide guidance for interventions and activities to implement standard, contact, droplet, and airborne precautions in the OR. The CDC guidance for Ebola HF1 provides precautions to implement in addition to the AORN recommendations2 that are specific Pr es s to patients with known or suspected Ebola HF. According to the CDC, heightened precautions for Ebola HF are recommended because of the “high rate of morbidity and mortality among infected patients, risk of human-to-human transmission, and lack of a FDA-approved vaccine and therapeutics.”1 Table 1 describes recommendations for personal protective equipment (PPE) for perioperative team members caring for a patient with known or suspected Ebola HF in the (OSHA)7 recommendations. in OR, as based on the CDC,1,3 AORN,2,4-6 and Occupational Safety and Health Administration le The CDC advises health care personnel to wear respiratory protection that is “at least as ic protective as a NIOSH-certified, fit-tested N95 filtering face piece respirator or higher (eg, rt powered air purifying respiratory, elastomeric respirator)”1 when caring for patients known or A suspected to have Ebola HF during aerosol-generating procedures. Because positive airway pressure respirators (PAPRs) and elastomeric respirators are not approved for use as a surgical mask, perioperative team members should take an abundance of caution when considering the use of PAPRs or elastomeric respirators in the OR. Use of PAPRs or elastomeric respirators, which are designed to protect the wearer and may not filter exhaled air, may contribute to air contamination in the OR by exhausting unfiltered air.8 This is an unresolved issue and further research is necessary to investigate this concern. Air contamination in the OR could increase the Page 2 of 8 EBOLA: PERIOPERATIVE CONSIDERATIONS CLINICAL ISSUES AHEAD OF PRINT risk of a patient developing a surgical site infection from a contaminated sterile field or surgical wound. Wearing surgical masks under a PAPR or elastomeric respirator in the OR to reduce the concern of air contamination invalidates the function of the respirator and may jeopardize the respiratory protection provided by these types of respirators. Therefore, the proposed benefits of respiratory protection to the health care workers may be in question and the patient is possibly at an increased risk of surgical site infection.9 A rt ic le in Pr es s Table 1. Personal Protective Equipment (PPE) for Perioperative Team Members Caring for a Patient with Ebola hemorrhagic fever. PPE for non-scrubbed team members should include Clean gloves, double.1 Gown, fluid resistant or impermeable.1,2 Either a face shield that fully covers the front and sides of the face or goggles. 1-3 Respiratory protection that is at least as protective as a National Institute for Occupational Safety and Health (NIOSH)–certified, fit-tested N95 filtering face piece respirator.1,2 Disposable shoe covers.1 Leg covers or boots, depending on the risk for exposure to blood/body fluids. 1-4 Fluid-resistant head covering or hood, depending on the risk for exposure to blood, body fluids, or other potentially infectious material.1,2,4* PPE for scrubbed team members: Sterile gloves, double.5,6 Sterile gown.5 Either a face shield that fully covers the front and sides of the face or goggles. 1-3 Respiratory protection that is at least as protective as a NIOSH-certified, fit-tested N95 filtering face piece respirator.1-3 Disposable shoe covers.1 Leg covers or boots, depending on the risk for exposure to blood, body fluids, or other potentially infectious material.1-4* Fluid-resistant head covering or hood, depending on the risk for exposure to blood, body fluids, or other potentially infectious materials.1,2,4 PPE for environmental services (EVS) team members: Clean gloves,8 doubled depending on the risk for exposure to blood, body fluids, or other potentially infectious materials.2 Fluid-resistant or impermeable gown.2,7 Either a face shield that fully covers the front and sides of the face or goggles. 1-3,7 Respiratory protection that is at least as protective as a NIOSH-certified, fit-tested N95 filtering face piece respirator1 or a facemask,7 depending on the time and air exchanges after the patient leaves the OR. 2** Disposable shoe covers.1,7 Leg covers or boots, depending on the risk for exposure to blood, body fluids, or other potentially infectious materials.1-4* Fluid-resistant head covering or hood, depending on the risk for exposure to blood, body fluids, or other potentially infectious materials.1,3,4* PPE for sterile processing team members: Gloves, heavy-duty.4,8 Fluid-resistant or impermeable gown.4,8 Either a face shield that fully covers the front and sides of the face or goggles. 4,8 Mask.4,8 Leg covers or boots.4 Page 3 of 8 EBOLA: PERIOPERATIVE CONSIDERATIONS CLINICAL ISSUES AHEAD OF PRINT *According to OSHA Bloodborne Pathogens 1910.1030,4 “Surgical caps or hoods and/or shoe covers or boots shall be worn in instances when gross contamination can reasonably be anticipated (e.g., autopsies, orthopaedic surgery).” Note: According to the AORN Recommended Practices for Surgical Attire,3 “head coverings commonly used in the perioperative setting (eg, bouffant caps) are worn for hair and skin containment and are not considered PPE. The Occupational Safety and Health Administration requires that PPE not permit blood, body fluids, or other potentially infectious materials to pass through or reach the employee's clothing, skin, eyes, or other mucous membranes under normal conditions of use.” ** If the EVS team member enters the OR before “adequate time has passed for air exchanges per hour to clean 99% of airborne particles from the air (eg, 15 air exchanges per hour for 28 minutes to remove 99.9% of airborne contaminants),”2(p 392) a N95 respirator should be worn according to airborne precautions. 1 If the EVS team member enters the room after “adequate time has passed for air exchanges per hour to clean 99% of airborne particles from the air” 2(p 392), a facemask should be worn to protect against skin and mucous membrane exposure of cleaning chemicals or contamination during environmental cleaning activities.7 ic le in Pr es s References 1.

As part of the risk assessment, the team should assess the benefits of respirator protection to health care workers versus the harm of the patient developing a surgical site infection from air contamination. The issue of PAPRs and elastomeric respirators in the OR is being evaluated by OSHA and NIOSH, but this issue remains unresolved because of lack of evidence. Some states, such as California, require the use of a PAPR for health care personnel when performing aerosol Page 4 of 8 EBOLA: PERIOPERATIVE CONSIDERATIONS CLINICAL ISSUES AHEAD OF PRINT generating procedures on patients with influenza, which underscores the importance of working closely with local and state health departments to ensure that regulations are followed. Although there have been no documented instances of transmission of Ebola HF from environmental surfaces, the CDC advises higher levels of precaution toward potentially contaminated surfaces because of “the apparent low infectious dose, potential of high virus titers in the blood of ill patients, and disease severity”3 of Ebola HF. According to the CDC, health Pr es s care personnel should use “a US Environmental Protection Agency (EPA)-registered hospital disinfectant with a label claim for a non-enveloped virus (eg, norovirus, rotavirus, adenovirus, polio virus)”3 for cleaning environmental surfaces during the care of patients with known or suspected Ebola HF. The disinfectant should be selected by a multidisciplinary team (eg, infection preventionists, environmental services personnel, perioperative nurses) at the health in care organization.10 If a surface cannot be disinfected (eg, sensitive electronic equipment), the perioperative team should cover the surface with a protective barrier that can be discarded after le the procedure.10 To apply disinfectants, perioperative team members should use disposable ic cleaning materials because the CDC advises that all contaminated textiles be discarded as rt regulated medical waste to reduce exposure risks.3 Additionally, all linens, nonfluid- A impermeable pillows or mattresses, and textile privacy curtains should be discarded as regulated medical waste per the CDC guidance and should be handled in accordance with local, state, and federal regulations.3 The US Department of Transportation’s (DOT) Hazardous Materials Regulations has classified Ebola HF as a Category A infectious substance, and as such the handling of this waste (eg, sharps, linens, PPE, cleaning byproducts, used health care products) must comply with regulations for Category A infectious substances.3 To further reduce the risk of Ebola HF exposure among personnel, the perioperative team should limit the amount of Page 5 of 8 EBOLA: PERIOPERATIVE CONSIDERATIONS CLINICAL ISSUES AHEAD OF PRINT surface contamination of with blood, body fluids, or other potentially infectious materials from the patient during the procedure and follow recommendations for sharps safety.6,7 Because of rapid advances in the medical sciences in particular, independent verification of diagnoses and medication dosages should be made. The CDC’s Ebola Hemorrhagic Fever guidelines are changing rapidly and clinicians are advised to consult the most recent CDC update for infection prevention and control recommendations Pr es s (http://www.cdc.gov/vhf/ebola/hcp/infection-prevention-and-control-recommendations.html).
