Pediatric Airway Management in COVID-19 Patients: Consensus Guidelines From the Society for Pediatric Anesthesia's Pediatric Difficult Intubation Collaborative and the Canadian Pediatric Anesthesia Society.

The severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) pandemic has challenged medical systems and clinicians globally to unforeseen levels. Rapid spread of COVID-19 has forced clinicians to care for patients with a highly contagious disease without evidence-based guidelines. Using a virtual modified nominal group technique, the Pediatric Difficult Intubation Collaborative (PeDI-C), which currently includes 35 hospitals from 6 countries, generated consensus guidelines on airway management in pediatric anesthesia based on expert opinion and early data about the disease. PeDI-C identified overarching goals during care, including minimizing aerosolized respiratory secretions, minimizing the number of clinicians in contact with a patient, and recognizing that undiagnosed asymptomatic patients may shed the virus and infect health care workers. Recommendations include administering anxiolytic medications, intravenous anesthetic inductions, tracheal intubation using video laryngoscopes and cuffed tracheal tubes, use of in-line suction catheters, and modifying workflow to recover patients from anesthesia in the operating room. Importantly, PeDI-C recommends that anesthesiologists consider using appropriate personal protective equipment when performing aerosol-generating medical procedures in asymptomatic children, in addition to known or suspected children with COVID-19. Airway procedures should be done in negative pressure rooms when available. Adequate time should be allowed for operating room cleaning and air filtration between surgical cases. Research using rigorous study designs is urgently needed to inform safe practices during the COVID-19 pandemic. Until further information is available, PeDI-C advises that clinicians consider these guidelines to enhance the safety of health care workers during airway management when performing aerosol-generating medical procedures. These guidelines have been endorsed by the Society for Pediatric Anesthesia and the Canadian Pediatric Anesthesia Society.

Coronavirus Disease 2019 (COVID-19), a pandemic infection caused by a positive-sense ribonucleic acid (RNA) virus named the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has strained health care systems, ignited fear, and dramatically changed the daily lives of people around the world. Clinicians must care for patients with a highly communicable disease while protecting themselves from a potentially lethal disease. Anesthesiologists are at particularly high risk of being exposed to SARS-CoV-2 because airway management, particularly tracheal intubation, positive pressure ventilation through a mask, and management of tracheostomy tubes, causes widespread aerosolization of thevirus (Table 1).[1,2] Though the virus appears to have its most damaging clinical effects in adult patients, infection does occur in children.[3-6] Indeed, in the Chinese experience, asymptomatic transmission of the virus from children to health care workers (HCWs) emerged as a significant risk.[4,5] How to manage the pediatric airway in patients who may or may not be symptomatic is the focus of this report. Further many routine pre–COVID-19 practices, such as mask induction of general anesthesia in anxious, crying, and agitated children or carrying them into the operating room (OR), may be less desirable because of the risk of viral exposure to the clinical staff.

Robust, evidence-based research to advise safe airway practices during the COVID-19 pandemic isnot yet available. Therefore, we sought to develop consensus guidelines from airway experts in pediatric anesthesiology. The Pediatric Difficult Intubation Collaborative (PeDI-C; pediregistry.org) is a special interest group of the Society for Pediatric Anesthesia (pedsanesthesia.org). The mission of PeDI-C is to advance the safety of pediatric airway management by facilitating multicenter research, quality improvement, and education. PeDI-C has led several multicenter studies on pediatric airway management.[7-10] PeDI-Ccurrently includes 35 hospitals from 6 countries and 10 additional hospitals that are being onboarded. The more than 100 PeDI-C members include many internationally recognized experts in pediatric airway management. PeDI-C hosts biannual in-person meetings and communicates year-round using an online active chat group on WhatsApp (https://www.whatsapp.com). Members discuss real-time management of difficult intubation cases and disseminate clinical best practices through the forum. Average messages increased from 4 per day in March 2019 to 77 per day during March 2020. The surge in messaging highlighted the global need for guidance about airway management during this COVID-19 pandemic. To help address this need, PeDI-C leadership organized a webinar to generate consensus guidelines about airway management during aerosol-generating medical procedures (AGMPs) in pediatric anesthesia.

METHODOLOGY

On March 23, 2020, PeDI-C members on the WhatsApp forum hosted a webinar to discuss and identify themes and formulate best practice guidelines for AGMPs during the COVID-19 pandemic based on expert opinion. We used a modified nominal group technique (NGT). The classic NGT technique yields prompt results but requires a face-to-face meeting.[11] Due to the travel restrictions and requirement for social distancing during the unfolding COVID-19 pandemic, PeDI-Cheld a virtual NGT. PeDI-C leadership advertised the virtual meeting on its WhatsApp channel. Participation was voluntary and open to all members. Zoom (https://www.zoom.us), an online video conferencing service for the virtual NGT, was used,allowing members to interact using audio and video. J.E.F. moderated the session. Preplanned topics for discussion included appropriate use of personal protective equipment (PPE), conduct of anesthesia, and management of at-risk care teams. Forty-four pediatric anesthesiologists and one otolaryngologist from 33 institutions attended the virtual NGT (Supplemental Digital Content 1, Material 1, http://links.lww.com/AA/D84). We analyzed audio, chat messages, and video recordings to identify themes and compared these themes to notes taken in realtime during the meeting by 3 PeDI-C members (J.E.F., P.C., andC.T.M.). We summarized the identified themes and shared them with PeDI-C membership for review, further input, and refinement (Table 2). Additionally, an investigator (C.T.M.) conducted a literature search using Ovid Medline, PubMed, and Google on March 24 and 25, 2020, using the search terms “COVID-19,” “SARS-CoV-2,” “children,” AND “pediatrics” to identify publications relevant to airway management in children with COVID-19.

RESULTS

Literature Search

We identified 30articles from the literature search (Supplemental Digital Content 1, Material 2, http://links.lww.com/AA/D84), none of which provided details on airway management during AGMPs.

Training and Context-Sensitive Simulation

As COVID-19 continues to spread all over the world, many organizations have implemented simulation sessions to train clinicians on basic donning and doffing of PPE. This training is commendable; however, PeDI-C identified the need for context-specific simulation (ie, simulation that reflects their specific role in the health care team).[12,13] For example, anesthesia clinicians should design simulation sessions focused on intubating and extubating COVID-19 patients in full appropriate PPE while minimizing exposure to and spread of the virus in the perioperative environment. Similarly, otolaryngologists would simulate performing an aerosolizing procedure with a clinical team while also minimizing OR exposure using various barrier techniques and PPE.

Protecting Clinicians

PeDI-Cagreed that clinicians who are at higher risk of morbidity and mortality from COVID-19 should be protected from clinical exposure.[14] Some suggestions included delegating these at-risk clinicians to staff telemedicine clinics or contribute to scholarly and administrative tasks while maintaining adequate physical distancing. PeDI-C discussed the importance of PPE for anesthesia clinicians; specifically, there was consensus that airway manipulation, such as endotracheal intubation or extubation, isAGMPs and therefore requires maximum protection.[1,15-19] The group also acknowledged that during times of crisis, such as the current pandemic, institutions might have PPE shortages. Several members emphasized that although equipment shortages are essential to consider, the highest priority should be the safety of care teams. Prioritizing the safety of HCWs can maximize the delivery of care for patients during a pandemic. PPE supplies are becoming available from manufacturers, donations, and release from national strategic stockpiles; however, clinicians are impossible to replace if quarantined, severely ill, or, worse yet, dead. PeDI-Cfelt that centers should err on the side of overprotection rather than underprotection. Nearly10% of HCWs in Italy and 14% in Spain have contracted COVID-19 with associated morbidity and mortality.[20] Inadequate PPE, deeper lung penetration of aerosolized viral particles, and a high burden of exposure may contribute to these infections. In centers with limited PPE supplies, PeDI-C felt that teams should be pared down to the minimum necessary, and cases should be consolidated into the fewest possible rooms to conserve PPE.

PeDI-C recognized that children infected with SARS-CoV-2 could shed the virus asymptomatically, even in stool, and infect others.[21-24] A case report of an asymptomatic well infant reported high viral loads for 16 days.[5] Anywhere from 18% to 31% of COVID-19-positive passengers (mostly adults) isolated on the Diamond Cruise ship never developed symptoms. Early periods of SARS-CoV-2 can lead to lower levels of sensitivity on screening tests.[25] Therefore, PeDI-C recommends appropriate PPE (N95 and face shield and powered, air-purifying respirator [PAPR]) for AGMPs in all children in areas with high community spread. PeDI-Calso recognized the importance of balancing the need for ideal PPE for AGMPs against the current global shortage of PPE. A PPE coach should be available to ensure correct donning and doffing of PPE. The US Centers for Disease Control and Prevention (CDC) offers educational videos of proper donning and doffing technique at https://www.cdc.gov/vhf/ebola/hcp/ppe-training/index.html.

Cognitive Aids

PeDI-Cidentified the need for cognitive aids to support clinical care and workflow during the pandemic.[26] PeDI-C encourages the creation and sharing of such cognitive aids for current and future pandemics. Careful attention must be paid to the design and composition of these aids so that they are easily readable and comprehensible. Figure 1 demonstrates an example of a cognitive aid for managing COVID-19 pediatric patients. Cognitive aids (eg, checklists) should be printed, laminated, and mounted in care locations.

Case Preparation

All drugs and equipment should be prepared and readily available before starting an anesthetic. This preparation reduces the need for clinicians to reach into the anesthesia workstation drawers and bins once the patient has entered the procedure room. Trash cans and sharps containers should be readily available and open to avoid dropping equipment on the floor, which increases viral dispersion. For anesthesia drug dispensing workstations that require touching the screen, a plastic shield should be placed over the screen to minimize contamination. Clinicians should leave badges, keys, cell phones, pagers, and pens outside the OR. Emergency phones may be kept in sealed bags to facilitate communication with other clinicians.

Premedication

Clinicians should consider the routine use of preprocedural sedatives to reduce anxiety and increase compliance when an intravenous (IV) is placed awake. Additionally, premedication may reduce the risk of vigorous crying and the need for physical restraints during inhalational inductions. Nasal administration of premedication is undesirable because of the potential for high viral loads and the risk of coughing and sneezing. PeDI-C did not recommend parental presence for the induction of anesthesia to conserve PPE and reduce clinician exposure to SARS-CoV-2. However, this will depend on the local infrastructure and practice especially in areas where PPE shortages are not of concern.

Intravenous Placement and Induction of Anesthesia

Because inhalational induction may increase exposure to respiratory droplets and aerosols, PeDI-Cmembers agreed that IV induction is preferred. However, clinicians should assess the child’s disposition to IV catheter placement as struggling to place a catheter may result in higher exposure to respiratory droplets if the child cries. PeDI-C recommended rapid sequence induction or modified rapid sequence to reduce the risk of reflex airway activation during intubation with associated aerosolization. Rapid Sequence Induction may not be feasible without severe hypoxemia in small children and patients with severe lung pathology. These patients should receive gentle positive pressure ventilation with the goal of using just enough tidal volume to achieve chest rise while maintaining a tight mask seal.

Mask Induction if Required

Clinicians should induce anesthesia with the lowest possible flow rates and maintain a tight mask seal.PeDI-C recommended avoiding bag-mask ventilation if feasible to reduce aerosolization. Several PeDI-C members recommended mask induction and direct laryngoscopy–assisted and video laryngoscopy–assisted intubation (Figure 2), using a transparent plastic barrier around the anesthesia elbow to minimize extensive contamination of the OR. A simulation using a 3-layer transparent plastic technique with a simulated cough with particles of similar size to the SARS-COV-2 virus indicates that this barrier may trap virus under the plastic drape creating a hot zone around the patient but reducing the exposure of clinicians.[27] The World Health Organization (WHO) guide for rational use of PPE encourages the use of “physical barriers to reduce exposure to COVID-19 virus.”[28]

Airway Device Placement

The PeDI-C agreed that a cuffed tracheal tube was the ideal device to secure the airway in children with COVID-19. PeDI-C recommends using video laryngoscopy for all intubations, if available, to reduce the laryngoscopist’s proximity to the patient’s airway.[29] The most experienced laryngoscopist should attempt tracheal intubation to minimize laryngoscopy time and the number of attempts. Open suctioning may create aerosols, and an in-line closed suction system is preferred.[1,17,30] If clinically appropriate, patients in the intensive care unit (ICU) should be intubated in the ICU (preferably in a negative pressure room) before transfer to the OR. PeDI-C felt that a supraglottic airway device with a good seal was acceptable in some cases. A simulated cough in a manikin model with a supraglottic airway device in place showed minimal aerosol dispersion (Supplemental Digital Content 2, Video 1, http://links.lww.com/AA/D85). Second-generation supraglottic airway devices have higher leak pressures than first-generation masks and should be considered.[31] PeDI-C agreed that the least desirable approaches were high- or low-flow nasal cannula or bag-mask ventilation, though these techniques may be unavoidable at times. A simple oxygen mask placed on top of a nasal cannula may reduce the risk of aerosol dispersion (Supplemental Digital Content 3, Video 2, http://links.lww.com/AA/D86). PeDI-C recommended avoiding techniques that bring the clinician’s face or stethoscope near the patient to verify leak pressures for endotracheal tube (ETT) and supraglottic airway (SGA). Clinicians can use the ventilator’s measurements of expired and inspired tidal volume and handheld manometers to titrate cuff inflation. Wireless stethoscopes and point-of-care ultrasound can be used to confirm bilateral ventilation of the lungs. A “high-quality” viral filter should be placed between the breathing circuit and the patient’s airway and another one at the end of the expiratory limb at the connection to the anesthesia machine as illustrated at

https://www.apsf.org/faq-on-anesthesia-machine-use-protection-and-decontamination-during-the-covid-19-pandemic/#machine.

Maintenance of Anesthesia

PeDI-C recommended that clinicians use full PPE during the entire operative case given the risk of accidental ventilator circuit disconnection, accidental extubation, and unquantified aerosolization from the procedure, especially airway, laparoscopic, and endoscopic procedures. PeDI-C recommended a transparent barrier over the airway device and patient’s head to trap any aerosolized virus. Others have used wet towels and gauze for the same purpose.[32]

Emergence and Extubation

If available, the clinician should use closed in-line suction to minimize aerosolization during tracheal tube suctioning (Figure 3A). Clinicians should consider deep extubation using techniques that minimize coughing and bucking during emergence, such as total IV anesthesia or dexmedetomidine.[33,34] Still, patients may cough during the subsequent emergence and recovery. Protective barriers can be helpful in all phases of care, and the WHO has recommended using them to reduce viral dispersion.[35] Supplemental Digital Content 4, Video 3, http://links.lww.com/AA/D87, demonstrates an example of transparent barrier techniques used by PeDI-C members during extubation.[27] In addition, PeDI-C agreed thatclinicians should consider placing a suction device under the barrier to create a negative pressure microenvironment which may scavenge droplets and aerosolized materials.

B, Viral filter (red circle) removed from anesthesia circuit and inserted between the endotracheal tube adapter and transport circuit.

PeDI-C recommends emerging and recovering COVID-19 patients and patients under investigation for COVID-19 in the OR, followed by direct transfer of the patient to the inpatient ward bypassing the postanesthesia care unit if possible. This change in workflow minimizes the number of exposed HCWs and nearby patients. For patients being admitted to the ICU postoperatively, extubating in the ICU is considered.

Pediatric anesthesiologists may be called upon to assist with the extubation of critically ill COVID-19 patients in the ICU. Advanced planning of workflows and procedures for emergent intubations outside the OR is critical and should include representatives from anesthesiology, critical care, respiratory therapists, hospitalists and nursing, and respiratory therapists.

Prepare for Adult Care

Pediatric anesthesiologists may be involved in providing care to adults using anesthesia ventilators. The Anesthesia Patient Safety Foundation and the American Society of Anesthesiologists have provided detailed guidance on how to repurpose anesthesia ventilators for ICU care.[36] In preparation for this possibility, we encourage anesthesiologists to familiarize themselves with these processes in collaboration with other key stakeholders.

Transporting Intubated Patients

Mechanically ventilated children with COVID-19 should be transported with a ventilator with viral filters on the patient side of the y-piece and the expiratory limb of the breathing circuit (Figure 3).[36] If a transport ventilator is not available, a viral filter should be placed on the tracheal tube during transport with the caveat that they increase the dead space in the circuit which may be significant in small children. Figure 4 demonstrates 2 positions of the viral filter with this consideration in mind. Tracheal intubation should be confirmed with capnography and visual observation of bilateral chest rise. Samples lines for capnography should be placed after viral filters. In some cases, viral filters can be removed from the anesthesia circuit and repurposed as a viral filter for a manual transport circuit (Figure 3A). Before transport, clinicians should weigh the risks and benefits of administering additional sedation or neuromuscular blockade to prevent coughing and bucking.

Infrastructure

The use of a negative pressure OR for AGMPs is recommended for all proven or suspected COVID-19 patients if feasible. Ensure adequate air exchange and filtration time of the ORs used for patients with COVID-19 and suspected cases before cleaning and preparing for the next case.[37] A chart of time needed for adequate air exchange is available at https://www.cdc.gov/infectioncontrol/guidelines/environmental/appendix/air.html#tableb1 (scroll down to Table B1). If negative pressure ORs are not available, high-efficiency particulate air (HEPA) filters that sufficiently filter the OR’s square footage were used. Also, try to avoid rooms with connected ventilation systems.

Difficult Airways

PeDI-C members identified the unique challenges involved in managing difficult airways in patients with known or suspected COVID-19. Many of the recommendations described above for tracheal intubation of normal airways apply to difficult airways as well. An airway team should be assembled, and all equipment should be setup in the OR and checked. The team should consider a just-in-time review before beginning airway management. The clinician with the most experience with the selected airway device should perform the tracheal intubation. PeDI-C ranked difficult airway management approaches as follows: video laryngoscopy as the primary technique followed by fiberoptic intubation through a supraglottic airway device, combined video laryngoscopy and fiberoptic bronchoscopy and finally freehand fiberoptic. Oral fiberoptic intubation is preferred over nasal fiberoptic intubation and minimizes passive oxygenation as tolerated. Hypoxia can be addressed with intermittent 2-hand mask ventilation to maintain a good seal and low tidal volumes. If safe to do so, consider administering a neuromuscular blocking agent after IV induction. Sugammadex should be immediately available to antagonize the neuromuscular blocking agent if needed. If warranted, perform mask ventilation with low tidal volumes using a 2-person technique to maintain a good seal. If nasal fiberoptic intubation is required, using an endoscopy mask (Supplemental Digital Content 1, Material 3, http://links.lww.com/AA/D84) is considered. Endoscopy masks have a diaphragm that seals around the fiberoptic scope but allows the tracheal tube to be advanced into the airway. It may be prudent to call early for personnel and equipment for a surgical airway. Prolonged attempts at intubation may be associated with increased aerosolization of the virus.

DISCUSSION

PeDI-C generated consensus guidelines for multiple aspects of pediatric anesthesia care during the COVID-19 pandemic. Our literature search yielded no articles investigating pediatric airway management in patients known or suspected of having COVID-19, further supporting the need for such guidelines. Additionally, rigorous studies of COVID-19 patients may be challenging, given the high infectivity of the disease.

PeDI-C identified the critical importance of protecting HCWs. SARS-CoV-2 infected 3300 HCWs in China and 20% of Italian HCWs with associated morbidity and mortality.[19,20,38] The PeDI-C recommendations regarding the use of PPE for all AGMPs are in line with consensus guidelines from the American Society of Anesthesiologists, Anesthesia Patient Safety Foundation, American Academy of Anesthesiologist Assistants, and the Association of Nurse Anesthetists.[39] PeDI-C recognized that many institutions are already facing inadequate PPE supplies and need to balance PPE use for routine care in asymptomatic patients with future demand for COVID-19 patients.[40] Some have argued that a surgical facemask and standard universal precautions are sufficient in asymptomatic untested patients for AGMPs and cite published literature to support this practice. One study compared the efficacy of N95 respirators to medical masks in preventing HCWs from acquiring influenza and other viral respiratory infections. They randomly assigned 2862 HCWs to N95 or a medical mask and found no difference in laboratory-confirmed influenza infections between the 2 groups: 207 (8.2%) in the N95 group, and 193 (7.2%) in the medical mask group (difference, 1%; 95% confidence interval [CI], −0.5% to 2.5%; P= .18).[41] Clinicians should not extrapolate these data to COVID-19 for 2 reasons. First, the SARS-CoV-2 virus is more contagious than influenza. The R0, also known as the basic reproductive number, is a measure of how contagious an infectious disease is, and indicates the expected number of people who will get the disease from an infected individual. The R0 of influenza is 1.2, while that of COVID-19 is estimated to be between 2 and 3.[42] Second, SARS-CoV-2 may aerosolize more readily than influenza and remain airborne longer.[43] Clinicians should err on the side of overprotection in asymptomatic patients until more rigorous data areavailable in children. Fortunately, new data from Italy and China suggest that the pediatric burden of the disease might be low (2,4). Data from the Virtual pediatric intensive care unit systems (www.myvps.org), a collaboration of 135 North American Pediatric Intensive Care Units, indicate that of 609 patients tested, 30 were COVID-19 positive as of March 29, 2020. These data should be considered in the context of limited testing and exponential spread, which means a low disease prevalence can change rapidly. We caution clinicians not to lower their guard because of a perceived low burden of disease in children.

There remain areas of controversy and need for future exploration, including the value of preprocedural testing for COVID-19, and ethical and legal considerations for the use of innovative but unapproved PPE. Some centers use COVID-19 screening tests to determine the type of PPE for AGMPs, reserving N95 masks for COVID-19 patients and standard surgical masks for negative patients. Using reverse transcription polymerase chain reaction (RT-PCR) testing for COVID-19 to determine PPE use in a limited resource setting makes sense. However, sensitivity for detection of COVID-19 can vary based on how the sample was obtained, the duration from infection to testing, and how the laboratory performed the test. Further, the potential for false negatives should be recognized and clinicians should not be falsely reassured by a negative test. If high-sensitivity testing for COVID-19 is negative in the child, PPE may not be required. Another area of concern is the potential for asymptomatic spread of SARS-CoV-2 from HCWs to patients. It may become necessary for all HCWs to undergo COVID-19 testing to prevent nosocomial infection.

We acknowledge several limitations. The guidelines outlined in this document are based on expert opinions from a diverse group of clinicians. Supportive evidence is referenced when available; however, there are few rigorous studies given the novelty of this disease. Although we searched multiple online repositories and search engines for articles, publication delays could have made some reports unavailable to us at the time of this writing, and not all articlesfrom the global medical community are available in the repositories we queried. Information is evolving quickly during this pandemic, and PeDI-C recognizes that an update to this document may be warranted as we learn more. Most importantly, each hospital will need to adapt these guidelines based on local regulations, availability of equipment, and the prevalence of the disease. These guidelines are meant to help clinicians deliver care that is safe for children as well as staff.

CONCLUSIONS

The Society for Pediatric Anesthesia’s PeDI-C developed consensus guidelines based on expert opinion and the limited available data to guide pediatric airway management during the COVID-19 pandemic. Pandemics of this magnitude are rare. We hope that these guidelines will support clinical care, workflow, and decision-making that maintain patient-centered care while protecting HCWs, our most valuable resource to fight the pandemic. Finally, PeDI-C hopes that these guidelines help prepare clinicians to safely and effectively fight this pandemic.
