Recommendations for airway management in a suspected or confirmed case with COVID-19. A protocol of the Department of Cardiovascular Anesthesia of the National Institute of Cardiology Ignacio Chávez / Recomendaciones para el manejo de la vía aérea en caso sospechoso y/o confirmado con COVID-19. Protocolo del Departamento de Anestesiología Cardiovascular del Instituto Nacional de Cardiología Ignacio Chávez

The new coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), detected in Wuhan, China, causes coronavirus disease 2019 (COVID-19), which was declared pandemic, and has caused more than 19 million confirmed cases and more than 700 thousand deaths worldwide. When our institution was converted to COVID's hospital since early April 2020, specific care protocols were developed, with the aim of improving the quality of care and safety of patients and the staff involved in their management. Airway management represents one of the highest risks of direct contact infection with aerosol generation (orotracheal intubation, secretion aspiration, extubation, cardiopulmonary resuscitation, high flow oxygen therapy, noninvasive ventilation, and invasive ventilation). We present the current recommendations for airway management as well as a step-by-step airway management protocol to carry out a more secure procedure based on the literature reported so far.

El nuevo coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), detectado en Wuhan (China), causante de la enfermedad por coronavirus 2019 (COVID-19), que se declaró como pandemia, ha causado más de 19 millones de casos confirmados y más de 700 mil muertes en el mundo. Nuestra institución se reconvirtió a hospital COVID desde principios de abril del 2020, con lo que se desarrollaron protocolos de atención específicos, con el objetivo de mejorar la calidad de atención y seguridad de los pacientes y el personal involucrado en su manejo. El manejo de la vía aérea representa uno de los riesgos más altos de contagio por contacto directo en la generación de aerosoles (intubación orotraqueal, aspiración de secreciones, extubación, resucitación cardiopulmonar, terapia de oxígeno de alto flujo, ventilación no invasiva y ventilación invasiva). Presentamos las recomendaciones actuales para el manejo de la vía aérea, así como un protocolo de manejo paso a paso para llevar a cabo un procedimiento con mayor seguridad basados en la literatura reportada hasta el momento.

Difficult Airway Management in Adult Coronavirus Disease 2019 Patients: Statement by the Society of Airway Management.

The coronavirus disease 2019 (COVID-19) disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), often results in severe hypoxemia requiring airway management. Because SARS-CoV-2 virus is spread via respiratory droplets, bag-mask ventilation, intubation, and extubation may place health care workers (HCW) at risk. While existing recommendations address airway management in patients with COVID-19, no guidance exists specifically for difficult airway management. Some strategies normally recommended for difficult airway management may not be ideal in the setting of COVID-19 infection. To address this issue, the Society for Airway Management (SAM) created a task force to review existing literature and current practice guidelines for difficult airway management by the American Society of Anesthesiologists Task Force on Management of the Difficult Airway. The SAM task force created recommendations for the management of known or suspected difficult airway in the setting of known or suspected COVID-19 infection. The goal of the task force was to optimize successful airway management while minimizing exposure risk. Each member conducted a literature review on specific clinical practice section utilizing standard search engines (PubMed, Ovid, Google Scholar). Existing recommendations and evidence for difficult airway management in the COVID-19 context were developed. Each specific recommendation was discussed among task force members and modified until unanimously approved by all task force members. Elements of Appraisal of Guidelines Research and Evaluation (AGREE) Reporting Checklist for dissemination of clinical practice guidelines were utilized to develop this statement. Airway management in the COVID-19 patient increases HCW exposure risk. Difficult airway management often takes longer and may involve multiple procedures with aerosolization potential, and strict adherence to personal protective equipment (PPE) protocols is mandatory to reduce risk to providers. When a patient's airway risk assessment suggests that awake tracheal intubation is an appropriate choice of technique, and procedures that may cause increased aerosolization of secretions should be avoided. Optimal preoxygenation before induction with a tight seal facemask may be performed to reduce the risk of hypoxemia. Unless the patient is experiencing oxygen desaturation, positive pressure bag-mask ventilation after induction may be avoided to reduce aerosolization. For optimal intubating conditions, patients should be anesthetized with full muscle relaxation. Videolaryngoscopy is recommended as a first-line strategy for airway management. If emergent invasive airway access is indicated, then we recommend a surgical technique such as scalpel-bougie-tube, rather than an aerosolizing generating procedure, such as transtracheal jet ventilation. This statement represents recommendations by the SAM task force for the difficult airway management of adults with COVID-19 with the goal to optimize successful airway management while minimizing the risk of clinician exposure.

A quantitative evaluation of aerosol generation during supraglottic airway insertion and removal.

Many guidelines consider supraglottic airway use to be an aerosol-generating procedure. This status requires increased levels of personal protective equipment, fallow time between cases and results in reduced operating theatre efficiency. Aerosol generation has never been quantitated during supraglottic airway use. To address this evidence gap, we conducted real-time aerosol monitoring (0.3-10-µm diameter) in ultraclean operating theatres during supraglottic airway insertion and removal. This showed very low background particle concentrations (median (IQR [range]) 1.6 (0-3.1 [0-4.0]) particles.l-1 ) against which the patient's tidal breathing produced a higher concentration of aerosol (4.0 (1.3-11.0 [0-44]) particles.l-1 , p = 0.048). The average aerosol concentration detected during supraglottic airway insertion (1.3 (1.0-4.2 [0-6.2]) particles.l-1 , n = 11), and removal (2.1 (0-17.5 [0-26.2]) particles.l-1 , n = 12) was no different to tidal breathing (p = 0.31 and p = 0.84, respectively). Comparison of supraglottic airway insertion and removal with a volitional cough (104 (66-169 [33-326]), n = 27), demonstrated that supraglottic airway insertion/removal sequences produced <4% of the aerosol compared with a single cough (p < 0.001). A transient aerosol increase was recorded during one complicated supraglottic airway insertion (which initially failed to provide a patent airway). Detailed analysis of this event showed an atypical particle size distribution and we subsequently identified multiple sources of non-respiratory aerosols that may be produced during airway management and can be considered as artefacts. These findings demonstrate supraglottic airway insertion/removal generates no more bio-aerosol than breathing and far less than a cough. This should inform the design of infection prevention strategies for anaesthetists and operating theatre staff caring for patients managed with supraglottic airways.

Unintended consequences: The impact of airway management modifications introduced in response to COVID-19 on intubations in a tertiary centre emergency department.

OBJECTIVE: In response to COVID-19, we introduced and examined the effect of a raft of modifications to standard practice on adverse events and first-attempt success (FAS) associated with ED intubation. METHODS: An analysis of prospectively collected registry data of all ED intubations over a 3-year period at an Australian Major Trauma Centre. During the first 6 months of the COVID-19 pandemic in Australia, we introduced modifications to standard practice to reduce the risk to staff including: aerosolisation reduction, comprehensive personal protective equipment for all intubations, regular low fidelity simulation with 'sign-off' for all medical and nursing staff, senior clinician laryngoscopist and the introduction of pre-drawn medications. RESULTS: There were 783 patients, 136 in the COVID-19 era and 647 in the pre-COVID-19 comparator group. The rate of hypoxia was higher during the COVID-19 era compared to pre-COVID-19 (18.4% vs 9.6%, P < 0.005). This occurred despite the FAS rate remaining very high (95.6% vs 93.8%, P = 0.42) and intubation being undertaken by more senior laryngoscopists (consultant 55.9% during COVID-19 vs 22.6% pre-COVID-19, P < 0.001). Other adverse events were similar before and during COVID-19 (hypotension 12.5% vs 7.9%, P = 0.082; bradycardia 1.5% vs 0.5%, P = 0.21). Video laryngoscopy was more likely to be used during COVID-19 (95.6% vs 82.5%, P < 0.001) and induction of anaesthesia more often used ketamine (66.9% vs 42.3%, P < 0.001) and rocuronium (86.8% vs 52.1%, P < 0.001). CONCLUSIONS: This raft of modifications to ED intubation was associated with significant increase in hypoxia despite a very high FAS rate and more senior first laryngoscopist.

Recommendations for developing clinical care protocols during pandemics: From theory and practice.

In 2019, a novel coronavirus called the severe acute respiratory syndrome coronavirus 2 led to the outbreak of the coronavirus disease 2019, which was deemed a pandemic by the World Health Organization in March 2020. Owing to the accelerated rate of mortality and utilization of hospital resources, health care systems had to adapt to these major changes. This affected patient care across all disciplines and specifically within the perioperative services. In this review, we discuss the strategies and pitfalls of how perioperative services in a large academic medical center responded to the initial onset of a pandemic, adjustments made to airway management and anesthesia specialty services - including critical care medicine, obstetric anesthesiology, and cardiac anesthesiology - and strategies for reopening surgical caseload during the pandemic.

Clinical recommendations for in-hospital airway management during aerosol-transmitting procedures in the setting of a viral pandemic.

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can lead to severe pneumonia and multiorgan failure. While most of the infected patients develop no or only mild symptoms, some need respiratory support or even invasive ventilation. The exact route of transmission is currently under investigation. While droplet exposure and direct contact seem to be the most significant ways of transmitting the disease, aerosol transmission appears to be possible under circumstances favored by high viral load. Despite the use of personal protective equipment (PPE), this situation potentially puts healthcare workers at risk of infection, especially if they are involved in airway management. Various recommendations and international guidelines aim to protect healthcare workers, although evidence-based research confirming the benefits of these approaches is still scarce. In this article, we summarize the current literature and recommendations for airway management of COVID-19 patients.

COVID-19 Pandemic: What Every Otolaryngologist-Head and Neck Surgeon Needs to Know for Safe Airway Management.

The novel coronavirus disease 2019 (COVID-19) pandemic has unfolded with remarkable speed, posing unprecedented challenges for health care systems and society. Otolaryngologists have a special role in responding to this crisis by virtue of expertise in airway management. Against the backdrop of nations struggling to contain the virus's spread and to manage hospital strain, otolaryngologists must partner with anesthesiologists and front-line health care teams to provide expert services in high-risk situations while reducing transmission. Airway management and airway endoscopy, whether awake or sedated, expose operators to infectious aerosols, posing risks to staff. This commentary provides background on the outbreak, highlights critical considerations around mitigating infectious aerosol contact, and outlines best practices for airway-related clinical decision making during the COVID-19 pandemic. What otolaryngologists need to know and what actions are required are considered alongside the implications of increasing demand for tracheostomy. Approaches to managing the airway are presented, emphasizing safety of patients and the health care team.

MIST (Modified Intubating Sequence for Transmissibility) Bundle for Infectious Diseases with Aerosol Hazard.

The current global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has magnified the risk to healthcare providers when inititiating airway management, and safe tracheal intubation has become of paramount importance. Mitigation of risk to frontline providers requires airway management to be an orchestrated exercise based on training and purposeful simulation. Role allocation and closed-loop communication form the foundation of this exercise. We describe a methodical, 10-step approach from decision-making and meticulous drug and equipment choices to donning of personal protective equipment, and procedural concerns. This bundled approach will help reduce unplanned actions, which in turn may reduce the risk of aerosol transmission during airway management in resource-limited settings.

COVID-19 Intubation Safety: A Multidisciplinary, Rapid-Cycle Model of Improvement.

The COVID-19 pandemic has forced the health care industry to develop dynamic protocols to maximize provider safety as aerosolizing procedures, specifically intubation, increase the risk of contracting SARS-CoV-2. The authors sought to create a quality improvement framework to ensure safe practices for intubating providers, and describe a multidisciplinary model developed at an academic tertiary care facility centered on rapid-cycle improvements and real-time gap analysis to track adherence to COVID-19 intubation safety protocols. The model included an Intubation Safety Checklist, a standardized documentation template for intubations, obtaining real-time feedback, and weekly multidisciplinary team meetings to review data and implement improvements. This study captured 68 intubations in suspected COVID-19 patients and demonstrated high personal protective equipment compliance at the institution, but also identified areas for process improvement. Overall, the authors posit that an interdisciplinary workgroup and the integration of standardized processes can be used to enhance intubation safety among providers during the COVID-19 pandemic.

Alternatives for establishing a surgical airway during the COVID-19 pandemic. / Alternativas para o estabelecimento de via aérea cirúrgica durante a pandemia de COVID-19.

Currently doctors and health professionals are facing a challenging pandemic caused by a new strain called 2019 Novel Coronavirus (COVID-19). Human infection with COVID-19 does not yet have the clinical spectrum fully described, and the pattern of lethality, mortality, infectivity and transmissibility is not known with precision. There is no specific vaccine or medication available. Treatment is supportive and nonspecific. In Brazil, as in the rest of the world, the number of COVID-19 cases has grown alarmingly, leading to an increase in the number of hospitalizations as well as in mortality from the disease. Currently, the states with the highest number of cases are, respectively, São Paulo, Rio de Janeiro, Distrito Federal and Ceará. The objective of this work is to offer alternatives in order to guide surgeons regarding the surgical management of the airways in patients with suspicion and / or confirmation for COVID-19 infection.

Atualmente médicos e profissionais da saúde encontram-se frente a uma pandemia desafiadora causada por uma nova cepa denominada 2019 Novel Coronavírus (COVID-19). A infecção humana pelo COVID-19 ainda não tem o espectro clínico completamente descrito, bem como não se sabe com precisão o padrão de letalidade, mortalidade, infectividade e transmissibilidade. Não há vacina ou medicamento específico disponível. O tratamento é de suporte e inespecífico. No Brasil, assim como no restante do mundo o número de casos de COVID-19 tem crescido de maneira alarmante levando a um aumento do número de internações assim como da mortalidade pela doença. Atualmente os estados com maior número de casos são, respectivamente, São Paulo, Rio de Janeiro, Distrito Federal e Ceará. O objetivo deste trabalho é oferecer alternativas a fim de orientar cirurgiões quanto ao manejo cirúrgico das vias aéreas em pacientes com suspeita e/ou confirmação para infecção pelo COVID-19.

European consensus recommendations for neonatal and paediatric retrievals of positive or suspected COVID-19 patients.

BACKGROUND: The 2020 novel coronavirus (SARS-Cov-2) pandemic necessitates tailored recommendations addressing specific procedures for neonatal and paediatric transport of suspected or positive COVID-19 patients. The aim of this consensus statement is to define guidelines for safe clinical care for children needing inter-facility transport while making sure that the clinical teams involved are sufficiently protected from SARS-CoV-2. METHODS: A taskforce, composed of members of the European Society of Paediatric and Neonatal Intensive Care (ESPNIC) Transport section and the European Society for Paediatric Research (ESPR), reviewed the published literature and used a rapid, two-step modified Delphi process to formulate recommendations regarding safety and clinical management during transport of COVID-19 patients. RESULTS: The joint taskforce consisted of a panel of 12 experts who reached an agreement on a set of 17 recommendations specifying pertinent aspects on neonatal and paediatric COVID-19 patient transport. These included: case definition, personal protective equipment, airway management, equipment and strategies for invasive and non-invasive ventilation, special considerations for incubator and open stretcher transports, parents on transport and decontamination of transport vehicles. CONCLUSIONS: Our consensus recommendations aim to define current best-practice and should help guide transport teams dealing with infants and children with COVID-19 to work safely and effectively. IMPACT: We present European consensus recommendations on pertinent measures for transporting infants and children in times of the coronavirus (SARS-Cov-2 /COVID-19) pandemic. A panel of experts reviewed the evidence around transporting infants and children with proven or suspected COVID-19. Specific guidance on aspects of personal protective equipment, airway management and considerations for incubator and open stretcher transports is presented. Based on scant evidence, best-practice recommendations for neonatal and paediatric transport teams are presented, aiming for the protection of teams and patients. We highlight gaps in knowledge and areas of future research.

Airway Management in the Operating Room and Interventional Suites in Known or Suspected COVID-19 Adult Patients: A Practical Review.

Current evidence suggests that coronavirus disease 2019 (COVID-19) spread occurs via respiratory droplets (particles >5 µm) and possibly through aerosol. The rate of transmission remains high during airway management. This was evident during the 2003 severe acute respiratory syndrome epidemic where those who were involved in tracheal intubation had a higher risk of infection than those who were not involved (odds ratio 6.6). We describe specific airway management principles for patients with known or suspected COVID-19 disease for an array of critical care and procedural settings. We conducted a thorough search of the available literature of airway management of COVID-19 across a variety of international settings. In addition, we have analyzed various medical professional body recommendations for common procedural practices such as interventional cardiology, gastroenterology, and pulmonology. A systematic process that aims to protect the operators involved via appropriate personal protective equipment, avoidance of unnecessary patient contact and minimalization of periprocedural aerosol generation are key components to successful airway management. For operating room cases requiring general anesthesia or complex interventional procedures, tracheal intubation should be the preferred option. For interventional procedures, when tracheal intubation is not indicated, cautious conscious sedation appears to be a reasonable approach. Awake intubation should be avoided unless it is absolutely necessary. Extubation is a high-risk procedure for aerosol and droplet spread and needs thorough planning and preparation. As updates and modifications in the management of COVID-19 are still evolving, local guidelines, appraised at regular intervals, are vital in optimizing clinical management.

Intubation outside of the operating room: new challenges and opportunities in COVID-19 era.

PURPOSE OF REVIEW: Airway management in patients outside the operating room is associated with increased difficulties and risks, and the setting of the COVID-19 global pandemic adds another layer of complexity. Therefore, endotracheal intubation (ETT) of a patient who is presumptive COVID-19 or COVID-19 positive presents an additional challenge to an anesthesiologist. The aim of this review is to summarize the important principles of airway management outside of the operating room during the COVID-19 pandemic. RECENT FINDINGS: Several professional societies have formulated guidelines on airway management COVID-19 suspect and proven patients. Additionally, anesthesiologists working in hospitals treating many infected patients have developed specialized teams responsible for airway management outside the operating room. These documents and protocols focus on the importance of wearing personal protective equipment and the skills of the providers responsible for securing the airway. Staff safety is always a priority when performing ETT outside operating room. SUMMARY: The COVID-19 pandemic redefined the management of patients requiring aerosol generating procedures (droplet and airborne precautions). ETT is one of them and anesthesiologists are experts in performing airway management. Although the operating room is a highly controlled environment, airway management outside of this setting is not always the easiest task.

Consensus statement: Safe Airway Society principles of airway management and tracheal intubation specific to the COVID-19 adult patient group.

INTRODUCTION: This statement was planned on 11 March 2020 to provide clinical guidance and aid staff preparation for the coronavirus disease 2019 (COVID-19) pandemic in Australia and New Zealand. It has been widely endorsed by relevant specialty colleges and societies. MAIN RECOMMENDATIONS: Generic guidelines exist for the intubation of different patient groups, as do resources to facilitate airway rescue and transition to the "can't intubate, can't oxygenate" scenario. They should be followed where they do not contradict our specific recommendations for the COVID-19 patient group. Consideration should be given to using a checklist that has been specifically modified for the COVID-19 patient group. Early intubation should be considered to prevent the additional risk to staff of emergency intubation and to avoid prolonged use of high flow nasal oxygen or non-invasive ventilation. Significant institutional preparation is required to optimise staff and patient safety in preparing for the airway management of the COVID-19 patient group. The principles for airway management should be the same for all patients with COVID-19 (asymptomatic, mild or critically unwell). Safe, simple, familiar, reliable and robust practices should be adopted for all episodes of airway management for patients with COVID-19. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: Airway clinicians in Australia and New Zealand should now already be involved in regular intensive training for the airway management of the COVID-19 patient group. This training should focus on the principles of early intervention, meticulous planning, vigilant infection control, efficient processes, clear communication and standardised practice.
