Perioperative Preparations for COVID-19: The Pediatric Cardiac Team Perspective

Abstract

WORLD leaders and their nations' healthcare systems have seldom been tested as they are currently with the emergence of a novel coronavirus from Hubei province, China, in late 2019. This virus has been named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). On March 11, 2020, the World Health Organization declared coronavirus disease 2019 (COVID-19) a pandemic. On March 29, 2020, the US Centers for Disease Control and Prevention issued a level 3 warning and a statement recommending that everyone should avoid nonessential travel.1Centers for Disease Control and Prevention.

The scientific advisory committee can quickly assemble documents to help inform the COVID-19 command centers, who then can disseminate critical information to all members of the healthcare team. There is no emergency in a pandemic. Taking the time to “don and doff” personal protective equipment (PPE) correctly protects our colleagues and us so that we all can continue to safely care for sick patients in the long term.16Chen W, Huang Y.

Healthcare facilities cannot inform healthcare workers (HCW) if any colleagues they work with have tested positive for COVID-19. Furthermore, not all HCWs who are ill with COVID-19 symptoms are tested. HCWs with presumed COVID-19 illness should not return to work until at least 7 days have passed since symptoms first appeared and at least 3 days of recovery as defined by resolution of fever without the use of fever-reducing medications and improvement in respiratory symptoms (eg, cough, shortness of breath). Other efforts to limit HCW exposure include screening all team members on entry to their healthcare facility, wearing masks in clinical areas, and social distancing.16Chen W, Huang Y.

Accessed April 3, 2020.Google Scholar For healthcare systems, the Centers for Disease Control and Prevention and World Health Organization guidelines for PPE should be followed. Local variations may be made depending on what equipment is available. Strategies to decrease the risk of exposure to viral particles during aerosolizing procedures include the use of a powered air purifying respirator devices or an N95 mask with a face shield.19Alhazzani W, Moller MH, Arabi YM, et al.

During the severe acute respiratory syndrome outbreak in 2003, HCWs who performed intubations had an increased risk of contracting the disease (odds ratio [OR]) 6.6), as were those who performed noninvasive ventilation (OR 3.1), tracheostomy (OR 4.2), and manual ventilation before intubation (OR 2.8)20Tran K Cimon K Severn M et al.Aerosol generating procedures and risk of transmission of acute respiratory infections to healthcare workers: A systematic review.PLoS One. 2012; 7: e35797Crossref PubMed Scopus (1177) Google Scholar,21Meng L, Qiu H, Wan L, et al.

Simpler strategies also include the use of large, clear “to-go” bags containing PPE such as protective face masks, filters to fit on the bag-mask, face shields, gowns, and gloves. Clear plastic household storage boxes can house powered air purifying respirator machines and hoods that can be cleaned easily between patient use. Due to the need to closely monitor available supplies and their use, there may be an advantage to creating a team of “PPE guardians.” These guardians often are nursing staff from low- census units who can be retrained as PPE guardians to help their frontline colleagues. Each PPE guardian must be familiar with the workflow of his or her assigned unit. They are trained to provide “just-in-time-training” for appropriate PPE use for colleagues and then monitor the donning and doffing process to ensure that team members do not contaminate themselves or others.22Cook TM.Personal protective equipment during the COVID-19 pandemic - a narrative review [e-pub ahead of print]. Anaesthesia. doi: 10.1111/anae.15071, Accessed May 19, 2020.Google Scholar Areas in the hospital that are not being used during this pandemic, such as conference rooms, can be used for PPE storage. The presence of a PPE guardian allows teams to understand what PPE is available and to provide oversight of PPE distribution. Guardians also can aid in helping teams clean and reuse some PPE. Many centers, including our own, are using ultraviolet light sterilization of N95 masks. This sterilization method uses ultraviolet C radiation to inactivate microorganisms by causing deoxyribonucleic acid damage, thereby preventing replication.23Hamzavi IH, Lyons AB, Kohli I, et al.

J Am Acad Dermatol. doi: 10.1016/j.jaad.2020.03.085, Accessed May 19, 2020.Google Scholar Within healthcare facilities, specific rooms are pressurized relative to their surrounding areas in order to protect their contents or the patients from surrounding airborne contaminants. Operating rooms, pharmacy workrooms, and trauma/resuscitation areas are among those where a positive- pressure state is designed to protect sterile medical equipment and patients from airborne bacteria, fungi, and viruses. These positively pressured areas are among the cleanest in the healthcare facility. Under normal operating circumstances, these steps help to ensure a sterile operating environment, with the goal of minimizing the likelihood of surgical site infection. However, with the current COVID-19 pandemic, it is recommended that operating rooms be converted to negative- pressure rooms (similar to triage and waiting rooms, microbiology laboratories, soiled workrooms, janitor's closets) so that infectious transmission or chemical contamination originating from within the room does not occur.24Miller SL Clements N Elliott SA et al.Implementing a negative-pressure isolation ward for a surge in airborne infectious patients.Am J Infect Control. 2017; 45: 652-659PubMed Scopus (34) Google Scholar Conceptually, the design of ventilation systems within the hospital requires air movement from clean to less clean areas. The Facility Guidelines Institute 2014 guidelines and state building codes mandated the minimum number of air exchanges per hour within the operating room, which usually is in the range of 15- to- 20 air exchanges per hour. Many, if not most, hospitals exceed this standard. The number of air exchanges per hour determines the time required for the removal of airborne pathogens with 99% efficiency.25Lee ST Liang CC Chien TY et al.Effect of ventilation rate on air cleanliness and energy consumption in operation rooms at rest.Environ Monit Assess. 2018; 190: 178Crossref PubMed Scopus (14) Google Scholar However, these models are imperfect because they assume the perfect mixing of air within the space and constant aerosolization. The location of air inflow within the operating room is often specifically designed so that it disperses any airborne contaminants downward from the patient and away from the anesthesiologist at the site where airway management typically occurs.26Medical Advisory S Air cleaning technologies: An evidence-based analysis.Ont Health Technol Assess Ser. 2005; 5: 1-52Google Scholar Rules governing design and capacity of hospital ventilation systems are governed by the Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health for the purposes of employee health and safety. Conversion of a positive- pressure room to a negative- pressure room may be accomplished by building an anteroom at the site of patient entry into the operating room and sealing off additional access points to the room. Airflow within the operating room also must be reversed.24Miller SL Clements N Elliott SA et al.Implementing a negative-pressure isolation ward for a surge in airborne infectious patients.Am J Infect Control. 2017; 45: 652-659PubMed Scopus (34) Google Scholar,27Chow TT Kwan A Lin Z et al.Conversion of operating theatre from positive to negative pressure environment.J Hosp Infect. 2006; 64: 371-378Abstract Full Text Full Text PDF PubMed Scopus (77) Google Scholar The anteroom allows for the passage of equipment and personnel without contaminating the surrounding environment. It should be large enough for the passage of a large hospital bed and permit adequate space for donning and doffing of PPE. In addition, it should have a self-closing door so that negative pressure in the room remains. The considerations for these changes are complex and require close collaboration with hospital epidemiology, facilities management, and industrial hygiene specialists.27Chow TT Kwan A Lin Z et al.Conversion of operating theatre from positive to negative pressure environment.J Hosp Infect. 2006; 64: 371-378Abstract Full Text Full Text PDF PubMed Scopus (77) Google Scholar In the context of a pandemic, minimizing environmental contamination by respiratory droplets becomes essential to maintaining the safety of HCWs, while maintaining efficient patient flow throughout the hospital. The essential role of environmental services staff members often is underrecognized and underappreciated. After the use of an operating room for a COVID-19 patient, allowing adequate time for aerosolized particles to settle and for air exchanges to occur (usually 60-90 minutes) is essential for the safety of environmental services staff members. This is counter to the usual production pressure that governs the perioperative environment.28Welt FGP, Shah PB, Aronow HD, et al.

Checklists designed to improve the thoroughness of the cleaning process help to ensure that operating room surfaces do not serve as a source of infection for HCWs. In addition, testing for residual biologic residue after cleaning, such as adenosine triphosphate testing, may serve as a check on the thoroughness of operating room cleanliness.30CloroxPro.

Palliative cardiac surgery for functional single- ventricle patients cannot always be delayed. Heart and lung transplantation programs must continue surveillance for rejection in their patients and currently are faced with the tough decision of who should undergo transplantation urgently or who can wait. Programs also have the difficult task of minimizing the risks of successfully transplanted patients from acquiring COVID-19 in the hospital. There are recent reports on the safe use of the cardiac operating room without contamination for emergency cardiac surgery in COVID-19–positive adult patients.31Zhao S Ling K Yan H et al.Anesthetic management of patients with COVID 19 infections during emergency procedures.J Cardiothorac Vasc Anesth. 2020; 34: 1125-1131Abstract Full Text Full Text PDF PubMed Scopus (79) Google Scholar,32He H, Zhao S, Han L, et al.

Even though most patients with COVID-19 improve rapidly after a mild disease course, a significant proportion develop hypoxemic respiratory failure with viral pneumonia and diffuse alveolar disease that can progress to the need for venovenous or arteriovenous extracorporeal membrane oxygenation (ECMO). Therefore, it is highly likely there will be an increased need for the pediatric catheterization laboratory to transition adolescents and young adults to ECMO in the hope of a recovery from COVID-19.34Bartlett RH Ogino MT Brodie D et al.Initial ELSO guidance document: ECMO for COVID-19 patients with severe cardiopulmonary failure.ASAIO J. 2020; 66: 472-474Crossref PubMed Scopus (199) Google Scholar The Extracorporeal Life Support Organization and all of its worldwide chapters have released guidelines to describe when and how to use ECMO in COVID-19 patients.34Bartlett RH Ogino MT Brodie D et al.Initial ELSO guidance document: ECMO for COVID-19 patients with severe cardiopulmonary failure.ASAIO J. 2020; 66: 472-474Crossref PubMed Scopus (199) Google Scholar They do not recommend institutions starting a new ECMO program just for COVID-19 patients, and currently there are shortages of ECMO equipment worldwide.35Song F Shi N Shan F et al.Emerging 2019 novel coronavirus (2019-nCoV) pneumonia.Radiology. 2020; 295: 210-217Crossref PubMed Scopus (795) Google Scholar Even before ECMO, COVID-19–positive patients may undergo a number of investigative and therapeutic procedures requiring the expertise of the cardiac anesthesiologist.

Another important consideration is to remove all possible emergency medications that may be required during the procedure from the anesthesia workstation. This will prevent the reopening of the anesthesia workstation and potential contamination of all anesthetic supplies in the workstation. Ideally, the anesthetic workstation should be covered in a plastic sheet as a barrier to reentry to help minimize cross-contamination. Catheterization laboratories and cardiac operating rooms use positive ventilation systems and are not designed for infection isolation. Therefore, these rooms will require conversion to an air neutral or negative- pressure room to care for COVID-19 patients safely. In addition, the room will require a terminal clean at the end of the procedure. In preparation for the COVID-19 pandemic, it is most important for hospitals to be able to increase their ICU beds to be able to care for the surge in COVID-19 patients. An example of this is a team in Italy who had to quickly ensure that enough ICU beds were available and that all staff were fully trained in the safe use of PPE.14Carenzo L, Costantini E, Greco M, et al.

Adding to the challenge of a surge in the patient population, staff members may become ill, leaving ICU teams understaffed.49Booth CM Stewart TE Severe acute respiratory syndrome and critical care medicine: the Toronto experience.Crit Care Med. 2005; 33: S53-S60Crossref PubMed Scopus (53) Google Scholar Cardiac anesthesiologists are very likely to be called on to aid in ICU patient care due to their expertise in cardiopulmonary physiology and procedural skills. Familiarity with pulmonary, vascular, and cardiac physiology enables the cardiac anesthesiologist with a unique skill set to care for COVID-19 patients in an expanded ICU setting. Some emergency room and ICU teams have developed procedural teams. Similar to airway teams, the most experienced personnel on these teams are able to obtain vascular access on unstable patients.14Carenzo L, Costantini E, Greco M, et al.

This allows a small group of experts to be exposed to a patient during times of high potential risk of viral aerosolization. Team members who are in a high-risk category for SARS-CoV-2 infection due to age or comorbidities should not be expected to participate in these COVID-19 teams but encouraged to support the team in other ways by taking care of patients at low risk of viral infection. The pediatric cardiac anesthesiologist is in a unique position to play a significant leadership role in the current rapidly changing COVID-19 pandemic. This freestanding editorial has highlighted the important hospital and regional initiatives in which the assistance of the pediatric cardiac anesthesiologist can help guide medical decision- making. In addition, considerations for the anesthetic care in the catheterization laboratory and cardiac operating room of COVID-19 patients have been reviewed.
