Awake airway endoscopy in mucopolysaccharidosis: a case report

Abstract Mucopolysaccharidosis (MPS) are a group of rare genetic inherited diseases with a progressive course due to the accumulation of glycosaminoglycans resulting in anatomic abnormalities and organ dysfunction, including the respiratory, cardiovascular, skeletal, and neurological systems that can increase the risk of anesthesia complications. Clinical manifestations are variable, multisystemic, and include severe morphological changes. The anesthetic management of these patients is complex, particularly airway management, which can be planned to include a fiberoptic airway investigation prior to surgery. We present two cases of patients with MPS type VI and VII who underwent fiberoptic airway mapping under conscious sedation, with no complications. Since MPS is a rare but challenging disease concerning the airway management, we propose a safe and effective anesthetic technique that could be used for fiberoptic bronchoscopy and allow fiberoptic-assisted tracheal intubation at the time of surgery.

Vía aérea difícil no prevista en paciente anunciada para cirugía de urgencia / Difficult airway not foreseen in patient announced for emergency surgery

Introducción: El manejo de la vía aérea, conceptualizado como el conjunto de maniobras y empleo de dispositivos que permiten una ventilación adecuada y segura en pacientes que por diversas condiciones clínicas lo requieren, llega a ser uno de los desafíos más importantes que enfrenta un anestesiólogo en su práctica. Se considera que el resultado final dependerá de las características del paciente, la disponibilidad de equipos, así como de su destreza y habilidades. Cuando no se tienen en cuenta estos aspectos, aumenta la incidencia de morbilidad y mortalidad perioperatoria. Objetivo: Describir la conducta anestesiológica ante una paciente con diagnóstico de vía aérea difícil no prevista durante el perioperatorio. Presentación de caso: Se presenta el caso de una paciente anunciada para cirugía de urgencia, sin antecedentes patológicos personales, con antecedente de anestesia para amigdalotomía en la niñez. A pesar de un interrogatorio y examen físico minucioso, con utilización de herramientas como los test predictivos de vía aérea difícil y el empleo de dispositivos para su abordaje, no fue posible la intubación y se hizo necesario un abordaje quirúrgico de urgencia. Conclusiones: La vía aérea es parte integral del manejo anestésico. En la actualidad no se cuenta con un método clínico capaz de incluir la valoración de todos los parámetros que sugieran la presencia de vía aérea difícil. Una historia preoperatoria detallada y minuciosa evaluación de esta puede identificar factores de riesgos potenciales, pero casos como estos demuestran que a pesar de las medidas que se puedan tomar, no se está exento de fracasar en la permeabilización de la vía aérea(AU)

Introduction: The management of the airway, conceptualized as the set of maneuvers and use of devices that allow adequate and safe ventilation in patients who require it due to various clinical conditions, becomes one of the most important challenges faced by an anesthesiologist in the practice. It is considered that the final result will depend on the characteristics of the patient, the availability of equipment, as well as their dexterity and skills. When these aspects are not taken into account, the incidence of perioperative morbidity and mortality increases. Objective: Describe the anesthesiological behavior in a patient with a difficult airway diagnosis not foreseen during the perioperative period. Case presentation: The case of a patient announced for emergency surgery, without a personal pathological history, with a history of anesthesia for tonsillectomy in childhood is presented. Despite a thorough interrogation and physical examination, with the use of tools such as predictive tests of difficult airway and the use of devices for their approach, intubation was not possible and an emergency surgical approach was necessary. Conclusions: The airway is an comprehensive part of anesthetic management. At present there is no clinical methods capable of including the assessment of all the parameters that suggest the presence of a difficult airway. A detailed preoperative history and thorough evaluation of this can identify potential risk factors, but cases like these show that despite the measures that can be taken, it is not exempt from failing to permeate the airway(AU)

Videolaringoscopia en el abordaje de la vía aérea durante la pandemia de la COVID-19 / Videolaryngoscopy for airway management during the COVID-19 pandemic

Introducción: A finales del año 2019 se reportaron casos de neumonía atípica en Wuhan provocados por un nuevo coronavirus. La intubación endotraqueal puede causar contaminación del personal de salud. Las pautas recientes prefieren la videolaringoscopia porque aumenta las posibilidades de intubación y evita del contacto cercano con el paciente. Objetivos: Describir el abordaje de la vía aérea con videolaringoscopia en pacientes con COVID-19 e identificar las principales complicaciones aparecidas durante la intubación endotraqueal. Métodos: Se realizó un estudio descriptivo, transversal, en el periodo de diciembre de 2020 a febrero de 2021, en el Centro Médico Naval de la Ciudad de México. El universo estuvo conformado por 178 pacientes con COVID-19 que requirieron intubación endotraqueal. Se tomó una muestra de 103 pacientes los cuales fueron atendidos por los médicos cubanos. Resultados: Los pacientes mayores de 60 años representaron el 63,1 por ciento de los casos y el sexo masculino el 65 por ciento El 42,1 por ciento tuvieron un predictor de vía aérea difícil y el 30,1 por ciento, dos o más predictores. Se visualizó completamente la glotis en el 39,8 por ciento de los casos y, parcialmente, en un 57,3 por ciento. La intubación al primer intento se logró en el 73,8 por ciento. Las principales complicaciones encontradas fueron la desaturación (33 por ciento) y la hipotensión arterial (37,9 por ciento). Conclusiones: La videolaringoscopia podría mejorar la visualización de la apertura glótica y la intubación endotraqueal al primer intento. La desaturación y la hipotensión arterial fueron complicaciones que podrían esperarse en los pacientes con la COVID-19 durante este procedimiento(AU)

Introduction: At the end of 2019, cases of atypical pneumonia were reported in Wuhan caused by a new coronavirus. Endotracheal intubation may cause contamination of healthcare personnel. According to recent guidelines, videolaryngoscopy is preferred, because it increases the chances of intubation and avoids close contact with the patient. Objectives: To describe airway management with videolaryngoscopy in patients with COVID-19 and to identify the main complications that appeared during endotracheal intubation. Methods: A descriptive and cross-sectional study was carried out, in the period from December 2020 to February 2021, at the Naval Medical Center in Mexico City. The universe consisted of 178 patients with COVID-19 who required endotracheal intubation. A sample of 103 patients was taken, who were cared for by Cuban doctors. Results: Patients older than 60 years represented 63.1 percent of the cases, while the male sex represented 65 percent. 42.1 percent had one predictor of difficult airway and 30.1 percent had two or more predictors. The glottis was visualized fully in 39.8 percent of cases and partially in 57.3 percent. Intubation on the first attempt was achieved in 73.8 percent. The main complications found were desaturation (33 percent) and arterial hypotension (37.9 percent). Conclusions: Videolaryngoscopy could improve visualization of the glottic opening and endotracheal intubation on the first attempt. Desaturation and hypotension were complications that could be expected in COVID-19 patients during this procedure(AU)

Actualización en el abordaje de la vía respiratoria del paciente obeso / Update on the approach to the obese patient respiratory tract

RESUMEN El manejo de la vía respiratoria es uno de los aspectos más importantes en Anestesia. Entre el 50 y 70 % de los paros cardiacos durante la anestesia general obedecen a dificultades en la intubación. Los pacientes obesos tienen un 30 % más de probabilidades de presentar intubación difícil con respecto a pacientes normopesos. También desarrollan desaturación de oxígeno más rápido, lo que aumenta el riesgo de complicaciones. Teniendo en cuenta lo anterior, se decidió realizar este trabajo, con el objetivo de actualizar sobre el uso de los métodos para el abordaje de la vía respiratoria en dichos pacientes. Se mostraron los criterios y resultados de investigaciones de autores sobre el tema. Se concluye que, a pesar de que el método más utilizado para abordar la vía aérea en obesos es la intubación orotraqueal con visión directa, se debe considerar el uso de máscara laríngea de intubación, fibroscopio flexible y videolaringoscopios, sobre todo en personas superobesas (AU).

ABSTRACT The respiratory tract management is one of the most important topics in anesthesia. Between 50 and 70 % of the heart arrests occurring during general anesthesia are due to intubation difficulties. Obese patients are 30 % more likely of presenting difficult intubation with respect to normal weight patients. They also develop oxygen desaturation faster, increasing the complication risk. Taking into consideration the above reasons, the authors decided to write this article, with the aim of updating on the methods to approach the respiratory tract in those patients. The authors' criteria and research outcomes on the theme are showed. It was concluded that even though the most used method to approach the airway in obese patients is the orotracheal intubation with direct vision, the use of a laryngeal intubation mask, flexible fiberscope and video laryngoscopes should be considered, especially in superobese patients (AU).

Dispositivos supraglóticos con acceso gástrico en colecistectomía laparoscópica / Supraglottic Devices with Gastric Access in Laparoscopic Cholecystectomy

Introducción: El abordaje de la vía aérea del paciente bajo cirugía laparoscópica representa múltiples retos para el anestesiólogo. Objetivo: Evaluar la efectividad y seguridad de tres dispositivos supraglóticos con acceso gástrico en el abordaje de la vía aérea de pacientes bajo colecistectomía laparoscópica. Métodos: Se realizó un estudio cuasiexperimental, prospectivo, longitudinal en el Hospital Universitario "General Calixto García", entre el 2017 y 2019. Se constituyeron tres grupos de 40 pacientes, según dispositivo: máscara laríngea proseal, máscara laríngea supreme y máscara I-gel. Se estudió: tiempo de inserción, número de intentos para colocación, facilidad de inserción de la sonda nasogástrica, presión y suficiencia de sellado orofaríngeo, presión pico con neumoperitoneo y complicaciones. Las variables cualitativas se analizaron con frecuencias absolutas y relativas, y las cuantitativas con medias y desviación estándar. Para la asociación entre variables cualitativas, se utilizó la prueba de chi-cuadrado, y el análisis de varianza para la asociación entre cuantitativas y cualitativas. Se consideró significativo valor de p < 0,05. Resultados: La máscara laríngea supreme se insertó con éxito al primer intento en la mayoría de los pacientes (p = 0,004). La I-gel registró el menor tiempo de inserción (10,05 ± 1,75 seg) y la Supreme mayor facilidad para la sonda nasogástrica (p < 0,001). La mayor presión de sellado fue con la máscara laríngea proseal (30,87 ± 2,60 cmH2O). Las complicaciones fueron pocas y similares con cada uno. Conclusiones: La utilización de dispositivos supraglóticos con acceso gástrico demostró seguridad y efectividad en pacientes intervenidos por colecistectomía laparoscópica(AU)

Introduction: Airway management in the patient undergoing laparoscopic surgery presents multiple challenges for the anesthesiologist. Objective: To assess the effectiveness and safety of three supraglottic devices with gastric access in the airway management in patients undergoing laparoscopic cholecystectomy. Methods: A quasiexperimental, prospective and longitudinal study was carried out, between 2017 and 2019, at General Calixto García University Hospital. Three groups of forty patients were made up, according to the usage of each device: ProSeal laryngeal mask, Supreme laryngeal mask, and I-gel mask. The following variables were studied: insertion time, number of placement attempts, ease of insertion of nasogastric tube, pressure and sufficiency of oropharyngeal sealing, peak pressure with pneumoperitoneum, and complications. Qualitative variables were analyzed with absolute and relative frequencies; and quantitative variables, with means and standard deviation. For the association between qualitative variables, the chi-square test was used, while variance analysis was used for the association between quantitative and qualitative variables. A value of P< 0.05 was considered significant. Results: The Supreme laryngeal mask was successfully inserted on the first attempt in most patients (P=0.004). The I-gel mask had the shortest insertion time (10.05±1.75 seconds), while the Supreme was the easiest for the nasogastric tube (P< 0.001). The highest sealing pressure was obtained with the ProSeal laryngeal mask (30.87±2.60 cmH2O). The complications were few and similar with each device. Conclusions: The use of supraglottic devices with gastric access showed safety and effectiveness in patients who underwent laparoscopic cholecystectomy(AU)

Laringoscopio híbrido: Una opción de costo razonable para el abordaje de la vía aérea difícil. Reporte de un caso / Hybrid laryngoscope: A reasonable option cost for approaching the airway difficulty. A case report

The laryngoscope is a primary tool that every medical professional who performs in airway care should know how to use. Although it's an irreplaceable tool, in the last decade have been considered transformations and modifications in them that have allowed the medical professional, especially the anesthesiologist to perform successfully for critical management especially in the context of unanticipated difficult airway, because most of the time the only available resource at hand is the laryngoscope and a malleable stylet that guides the orotracheal. The new technological age of visual instruments such as video cameras and photographs many of these with small sizes, has been used in the manufacture of video laryngoscopes that today are used, which have managed to approach the aerea in a minimally traumatic way and also safeguard lives. Our hydrid video laryngoscope is a handcrafted tool made of high-quality elements, strength, durability and low cost.

El laringoscopio es una herramienta primordial que todo profesional médico que se desempeña en la atención de la vía aérea debería saber utilizar. Pese a ser un dispositivo insustituible, en la última década se han considerado transformaciones y modificaciones en los mismos que le han permitido al profesional de la medicina, fundamentalmente al anestesiólogo, desempeñarse exitosamente durante el manejo crítico especialmente en el contexto de vía aérea difícil no anticipada, en el que la mayoría de las veces el único recurso disponible a la mano es el laringoscopio y un estilete maleable que sirve de guía para dirigir la sonda orotraqueal. La nueva era tecnológica de los instrumentos visuales como cámaras de video y fotografía, (muchos de estos con tamaños reducidos) han sido empleados en la fabricación de videolaringoscopios que hoy en día se utilizan y que han logrado abordar la vía aérea de manera mínimamente traumática, así mismo, salvaguardar vidas. Nuestro videolaringoscopio híbrido es una herramienta artesanal fabricada con elementos de alta calidad, resistencia, durabilidad y bajo costo.

Bloqueio neuromuscular e manuseio das vias aéreas na intubação endotraqueal em unidades de terapia intensiva brasileiras: um levantamento nacional / Neuromuscular blockade and airway management during endotracheal intubation in Brazilian intensive care units: a national survey

RESUMO Objetivo: Descrever o uso do bloqueio neuromuscular e de outras práticas entre os médicos brasileiros atuantes em unidades de terapia intensiva para pacientes adultos. Métodos: Um levantamento nacional on-line foi aplicado a intensivistas brasileiros. As questões foram selecionadas utilizando o método Delphi e avaliavam os dados demográficos dos médicos, as características da unidade de terapia intensiva, as práticas relativas ao manuseio das vias aéreas e o uso de bloqueio neuromuscular e sedação durante a intubação endotraqueal na unidade de terapia intensiva. Como desfecho secundário, aplicamos uma análise multivariada para avaliar fatores associados com o uso do bloqueio neuromuscular. Resultados: Responderam ao questionário 565 intensivistas de todas as regiões do país. A maioria dos que responderam era homens (65%), com média de idade de 38 ± 8,4 anos, e 58,5% dos participantes tinham título de especialista em terapia intensiva. Apenas 40,7% dos intensivistas relataram o uso de bloqueio neuromuscular durante todas ou em mais de 75% das intubações endotraqueais. Na análise multivariada, o número de intubações realizadas por mês e a especialização do médico em anestesiologia se associaram diretamente com o uso frequente de bloqueio neuromuscular. Etomidato e cetamina foram utilizados mais comumente na situação clínica de hipotensão e choque, enquanto propofol e midazolam foram mais comumente prescritos em situações de estabilidade hemodinâmica. Conclusão: O relato de uso de bloqueio neuromuscular foi baixo entre intensivistas, e os fármacos sedativos foram escolhidos segundo a estabilidade hemodinâmica do paciente. Estes resultados podem ajudar no delineamento de futuros estudos relativos ao manuseio das vias aéreas no Brasil.

Abstract Objective: To describe the use of neuromuscular blockade as well as other practices among Brazilian physicians in adult intensive care units. Methods: An online national survey was designed and administered to Brazilian intensivists. Questions were selected using the Delphi method and assessed physicians' demographic data, intensive care unit characteristics, practices regarding airway management, use of neuromuscular blockade and sedation during endotracheal intubation in the intensive care unit. As a secondary outcome, we applied a multivariate analysis to evaluate factors associated with the use of neuromuscular blockade. Results: Five hundred sixty-five intensivists from all Brazilian regions responded to the questionnaire. The majority of respondents were male (65%), with a mean age of 38 ( 8.4 years, and 58.5% had a board certification in critical care. Only 40.7% of the intensivists reported the use of neuromuscular blockade during all or in more than 75% of endotracheal intubations. In the multivariate analysis, the number of intubations performed monthly and physician specialization in anesthesiology were directly associated with frequent use of neuromuscular blockade. Etomidate and ketamine were more commonly used in the clinical situation of hypotension and shock, while propofol and midazolam were more commonly prescribed in the situation of clinical stability. Conclusion: The reported use of neuromuscular blockade was low among intensivists, and sedative drugs were chosen in accordance with patient hemodynamic stability. These results may help the design of future studies regarding airway management in Brazil.

Conclusions: The management of the airway in patients with Sagliker Syndrome requires experience, since inadequate management compromises the lives of patients.

Técnica EXIT como manejo de la vía aérea en masas gigantes congénitas de cuello / Ex-Utero Intrapartum Treatment for airway management in congenital giant neck masses

Resumen: Introducción: Las masas congénitas de cabeza y cuello se asocian a asfixia perinatal e injuria cerebral con elevada mortalidad. La técnica EXIT (Ex Útero Intrapartum Treatment) consiste en asegurar la vía aérea del neonato, sin interrumpir la oxigenación y perfusión materno-fetal a través del soporte placentario. Esta técnica no ha sido estandarizada en países de medianos ingresos. Objetivo: Describir el caso clínico de 2 neonatos manejados mediante la técnica EXIT. Caso Clínico: Se reportan dos casos, uno con malformación linfática diagnosticada a la semana 20 gestación y el segundo con tiromegalia y polihidramnios diagnosticados a la semana 35 de gestación. En ambos casos, duran te la cesárea se realizó la técnica EXIT con un equipo conformado por neonatólogo, ginecólogo, anestesiólogo, cirujano pediatra, otorrinolaringólogo, enfermero y terapeuta respiratorio. En los dos pacientes se logró asegurar la vía aérea mediante intubación orotraqueal al primer intento. En el caso 1 se confirmó la malformación linfática y recibió escleroterapia, y en el caso 2 se diagnosticó hipotiroidismo congénito asociado a bocio, que fue manejado con levotiroxina. Los pacientes se mantuvieron 7 y 9 días con ventilación mecánica invasiva respectivamente y egresaron sin complicaciones respiratorias. Conclusiones: La técnica EXIT en estos casos fue un procedimiento seguro, llevado a cabo sin inconvenientes. Se necesita un equipo multidisciplinario y la disponibilidad de una unidad de cuidados intensivos neonatales, con el objetivo de reducir potenciales complica ciones y garantizar el manejo postnatal. Para lograr su ejecución, es indispensable el diagnóstico prenatal oportuno.

Abstract: Introduction: Congenital head and neck masses are associated with perinatal asphyxia and brain injury, increasing the risk of death. The EXIT (Ex Utero Intrapartum Treatment) technique con sists of ensuring the newborn's airway while is still receiving placental support. This technique has not been standardized in developing countries. Objective: To describe the clinical outcomes of two infants who underwent the EXIT technique. Clinical Case: We present two cases, one with lymphatic malformation diagnosed at 20 weeks of gestational age (WGE) and the second one, a preterm newborn with thyromegaly and polyhydramnios, diagnosed at 35 WGE. In both cases, during the C-section, the EXIT technique was performed with a team of a neonatologist, a gyne cologist, an anesthesiologist, a pediatric surgeon, an otolaryngologist, a nurse, and a respiratory therapist. In both patients, the neonatologist achieved to secure the airway through orotracheal intubation at the first attempt. In the first case, lymphatic malformation was confirmed and re ceived sclerotherapy, and the second one was diagnosed with congenital hypothyroidism which was managed with levothyroxine. The patients needed invasive mechanical ventilation for 7 and 9 days, respectively, and were discharged without respiratory complications. Conclusions: In these patients, the EXIT technique was a safe procedure, carried out without inconvenience. A multi disciplinary approach and the availability of a neonatal intensive care unit are needed to reduce potential complications and ensure postnatal management. Timely prenatal diagnosis is essential to perform this technique.

Pituitary tumor resection in a patient with SARS-CoV-2 (COVID-19) infection. A case report and suggested airway management guidelines / Assistência perioperatória de paciente com infecção pelo SARS-CoV-2 (COVID-19) submetido a ressecção de tumor de hipófise urgente. Relato de caso e diretrizes para manejo de via aérea

Abstract The 2020 pandemic caused by the novel coronavirus, COVID-19, had its headquarters in China. It causes Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and presents a broad spectrum of clinical manifestations, ranging from entirely asymptomatic through severe acute respiratory failure and death. Presuming a significant quantity of ventilator-dependent patients, several institutions strategically delayed elective surgeries. Particularly procedures performed involving the nasal mucosa, such as a transsphenoidal approach of the pituitary gland, considering the tremendous level of viral shedding. Nevertheless, critical cases demand expeditious resolution. Those situations are severe pituitary apoplexy, declining consciousness level, or risk of acute visual loss. This case presents a successful urgent perioperative management of a 47 year-old male COVID-19 positive patient who presented to the Emergency Department with a left frontal headache that culminated with diplopia, left eye ptosis, and left visual acuity loss after 5 days. Transsphenoidal hypophysectomy was uneventfully performed, and the patient was discharged from the hospital on postoperative day four. It additionally describes in detail the University of Mississippi Medical Center airway management algorithm for patients infected with the novel coronavirus who need emergent surgical attention.

Resumo A pandemia de 2020 causada pelo novo coronavírus, COVID-19, teve seu epicentro na China. Causa Síndrome Respiratória Aguda Grave pelo Coronavírus 2 (SARS-CoV-2) e apresenta um amplo espectro de manifestações clínicas, que vão desde nenhum sintoma a insuficiência respiratória aguda grave e óbito. Com a expectativa de um número significativo de pacientes dependentes de ventilador, várias instituições estrategicamente adiaram cirurgias eletivas. Esse é o caso principalmente de procedimentos envolvendo a mucosa nasal, como a via transesfenoidal para a hipófise, devido ao nível imenso de disseminação de material viral. Não obstante, casos críticos requerem resolução acelerada. Essas situações são grave apoplexia hipofisária, diminuição do nível de consciência ou risco de perda visual aguda. O presente caso relata o manejo perioperatório bem sucedido de urgência de paciente do sexo masculino de 47 anos de idade com COVID-19 que chegou ao Pronto Socorro com cefaleia frontal à esquerda que culminou com diplopia, ptose do olho esquerdo e perda de acuidade visual à esquerda após 5 dias. A hipofisectomia transesfenoidal ocorreu sem intercorrências e o paciente recebeu alta do hospital no quarto dia do pós-operatório. Adicionalmente, descrevemos em detalhe o algoritmo de manejo de via aérea da University of Mississippi Medical Center para pacientes infectados pelo novo coronavírus e que necessitam de atenção cirúrgica de emergência.

Manejo de vía aérea en pandemia. Caso clínico / Difficult airway during pandemia: Case report

We present a 38 years female patient with known difficult airway associated with an important anatomic deformation due to a tumoral removal back in 2014 (maxilectomy). This patient was scheduled for a new tumoral resection at the base of the skull, which was considered a potential regrowth of her maxilar sinus cancer, and because of that, the surgery admitted no delays. A multi-disciplinary approach is convenied and an AFOI with topical airway anesthesia and dexmedetomidine sedation is planned to secure the airway during surgery. The main Objective was to optimize the protective measures against SARS CoV2 transmission while securing spontaneous ventilation and patient collaboration during the procedure. To achieve this it was necessary a complex and multi-disciplinary teamwork between de intervening personal. Eventually the airway approach was successful and the surgery was carried out uneventfully. The patient was extubate and taken to the post anesthesia care unit with no recall nor sequel of the procedure.

Presentamos un caso de una paciente de 38 años con predictores de vía aérea dificultosa anticipada, asociada a importante alteración anatómica secundaria a maxilectomía, por patología tumoral, en el año 2014. Actualmente, se sometió a resección tumoral de base de cráneo, considerada una patología no diferible (tiempo sensible) en el contexto de pandemia por COVID-19. Decidimos aplicar un plan de manejo multidisciplinario e intubación orotraqueal vigil mediante fibrobroncoscopia asociada a sedación superficial con dexmedetomidina y anestesia tópica. El objetivo principal fue maximizar las medidas de seguridad, manteniendo la ventilación espontánea y colaboración de la paciente durante el procedimiento. Finalmente, resultó exitoso, siendo la paciente extubada en el quirófano pasando luego a la Unidad de Recuperación Postanestésica, sin manifestar recuerdos ni secuelas del procedimiento realizado para concluir su postoperatorio en sala común.

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

RESUMO 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.

ABSTRACT 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.

Definiciones operativas y protocolo anestésico durante la pandemia producida por SARS-CoV-2 en un programa de cirugía cardíaca pediátrica / Operative definitions and anesthetic protocol during the SARS-CoV-2 pandemic in a pediatric cardiac surgery program

The clinical characteristics of the pediatric population infected with the SARS-CoV-2 virus in general are not as severe as in the adult population, so they can be considered asymptomatic carriers. The pediatric patient with congenital heart disease are considered a high risk group of contagion in the SARS-CoV-2 pandemic, so healthcare personnel who interact with patients must have established guidelines to avoid transmission and spread of the disease. Each country is commanded by the central guidelines established by its health system considering operative definitions and protocols, but in certain places these guidelines do not fulfill international standards, as those proposed by the World Health Organization. In this communication we have done a current literature review and adaptation of the recommendations to face the infectious outbreak due to the SARS-CoV-2 virus in pediatric cardiovascular surgery programs, specifically in the ​​anesthesiology area. We also analyze the type of personal protective equipment that should be used in each area of ​​patient management, changes in the environment of work areas, shift times of health personnel, the protection of personnel performing transesophageal echocardiography, modification of the airway management algorithms, proper placement and withdrawal of personal protective equipment, patients transfer between wards or other services, and adequate disinfection of airway equipment used.

Las características clínicas de la población pediátrica contagiada del virus SARS-CoV-2 en general no son tan severas como en la población adulta, por lo que pueden ser considerados portadores asintomáticos. El paciente pediátrico con cardiopatía congénita pertenece a un grupo de alto riesgo de contagio dentro de la pandemia producida por el SARS-CoV-2, por lo que el personal sanitario que interactúe con los pacientes debe tener lineamientos establecidos para evitar la transmisión y propagación de la enfermedad. Cada país se rige por las guías centrales establecidas por su sistema de salud en cuanto a definiciones operativas y protocolos, pero en algunos lugares estas directrices no cumplen las metas internacionales, como las propuestas por la Organización Mundial de la Salud. En este comunicado hemos realizado una revisión de la literatura actual y adaptación de las recomendaciones para enfrentar el brote infeccioso por el virus SARS-CoV-2 en los programas de cirugía cardiovascular pediátrica, específicamente en el área de anestesiología. También analizamos el tipo de equipo de protección personal que debe ser utilizado en cada área del manejo de pacientes, cambios del ambiente de las áreas de trabajo, rotación de personal, la protección del personal que realiza ecocardiografía transesofágica, modificación de los algoritmos de manejo de la vía aérea, colocación y retiro correctos del equipo de protección personal, traslado de los pacientes entre servicios, y adecuada desinfección del equipo utilizado en el manejo de la vía aérea.

Simulation of difficult airway management for residents: prospective comparative study / Simulação de manejo de via aérea difícil para residentes: estudo comparativo prospectivo

Abstract Background and objectives Procedural simulation training for difficult airway management offers acquisition opportunities. The hypothesis was that 3 hours of procedural simulation training for difficult airway management improves: acquisition, behavior, and patient outcomes as reported 6 months later. Methods This prospective comparative study took place in two medical universities. Second-year residents of anesthesiology and intensive care from one region participated in 3 h procedural simulation (intervention group). No intervention was scheduled for their peers from the other region (control). Prior to simulation and 6 months later, residents filled-out the same self-assessment form collecting experience with different devices. The control group filled-out the same forms simultaneously. The primary endpoint was the frequency of use of each difficult airway management device within groups at 6 months. Secondary endpoints included modifications of knowledge, skills, and patient outcomes with each device at 6 months. Intervention cost assessment was provided. Results 44 residents were included in the intervention group and 16 in the control group. No significant difference was observed for the primary endpoint. In the intervention group, improvement of knowledge and skills was observed at 6 months for each device, and improvement of patient outcomes was observed with the use of malleable intubation stylet and Eschmann introducer. No such improvement was observed in the control group. Estimated intervention cost was 406€ per resident. Conclusions A 3 h procedural simulation training for difficult airway management did not improve the frequency of use of devices at 6 months by residents. However, other positive effects suggest exploring the best ratio of time/acquisition efficiency with difficult airway management simulation. ClinicalTrials.gov Identifier NCT02470195.

Resumo Justificativa e objetivos O treinamento em simulação para o manejo de via aérea difícil oferece oportunidades de aprendizagem. A hipótese foi que um treinamento em simulação de procedimentos de três horas, para o manejo de via aérea difícil, melhoraria o aprendizado, o comportamento e os resultados dos pacientes, conforme relatado seis meses após o treinamento. Métodos Este estudo comparativo prospectivo foi realizado em duas universidades médicas. Residentes do segundo ano de anestesiologia e terapia intensiva de uma região participaram de um curso de três horas em simulação de procedimentos (grupo intervenção). Nenhuma intervenção foi programada para seus pares da outra região (grupo controle). Antes da simulação e seis meses após, os residentes preencheram a mesma ficha de autoavaliação sobre sua experiência com diferentes dispositivos. O grupo controle preencheu os mesmos formulários simultaneamente. O desfecho primário foi a frequência de uso de cada dispositivo para o manejo de via aérea difícil dentro dos grupos aos seis meses. Os pontos de corte secundários incluíram modificações em relação ao conhecimento, às habilidades e aos resultados dos pacientes com cada dispositivo aos seis meses. A avaliação do custo da intervenção foi registrada. Resultados Foram incluídos no grupo intervenção 44 residentes e 16 no grupo controle. Nenhuma diferença significativa foi observada para o ponto de corte primário. No grupo intervenção, a melhoria do conhecimento e das habilidades foi observada aos seis meses para cada dispositivo e a melhoria dos desfechos dos pacientes foi analisada com o uso de estilete maleável e do introdutor de Eschmann para intubação. Nenhuma melhoria foi observada no grupo controle. O custo da intervenção estimado foi de 406€ por residente. Conclusões Um treinamento simulado de três horas para o manejo de via aérea difícil não melhorou a frequência do uso de dispositivos pelos residentes aos seis meses. No entanto, outros efeitos positivos sugerem a exploração da melhor relação tempo/eficiência de aquisição de conhecimento com a simulação do manejo de via aérea difícil.
