Complications and degree of difficulty of orotracheal intubation in the Intensive Care Unit before and after the establishment of an intubation protocol for critically ill patients: a prospective, observational study.

OBJECTIVE: The objective of our study was to compare the degree of difficulty and complications related to tracheal intubation in an Intensive Care Unit (ICU) before and after the introduction of an intubation protocol based on the Difficult Airway Society guidelines for the management of tracheal intubation in critically ill adults, published in 2018. METHODS: Prospective, observational study comparing all intubations performed in our ICU over 2 periods: pre-protocol (January 2015-January 2019) and post-protocol (February 2019-July 2022). The material used for intubation, the degree of difficulty, and intubation-related complications were recorded. RESULTS: During the study period, 661 patients were intubated - 437 in the pre-protocol period (96% by direct laryngoscopy) and 224 in the post-protocol period (53% with direct laryngoscopy, 46% with video laryngoscopy). We observed an improvement in laryngeal view in the post-protocol period compared to the pre-protocol period (Cormack-Lehane ≥ 2b in 7.6% vs. 29.8%, p < 0.001), and a decrease in the number of moderate-to-severely difficult intubations (6.7% vs. 17.4%, p < 0.001). The first-pass success rate was 92.8% in the post-protocol period compared to 90.2% pre-protocol (p = 0.508). We did not find significant differences in complications between the periods studied. CONCLUSIONS: Intubations performed in the post-protocol period were associated with improved laryngeal view and fewer cases of difficult intubation compared with the pre-protocol period.

Approaching the airway in prehospital emergency is a common and potentially life-saving practice.

Management by the environment is complex, which means a much higher percentage of difficult airways than in a regulated environment such as the operating room. Failure or prolonged attempt to tracheal intubation is associated with unfavorable outcomes and serious complications. Acute epiglottitis is a life-threatening disorder, classified as a medical emergency within the diseases of the upper respiratory airway and characterized by its sudden and deadly evolution if rapid intubation is not achieved to allow oxygenation of the patient. We describe a 36-year-old male patient with stridor, dyspnea e hypoxemia due to total obstruction of airway, caused by an acute epiglottitis. We aim to highlight this unusual injury and its management from the prehospital until discharge illustrating the severity of the clinical presentation, current treatment and outcome.

Airway management of COVID-19 patients: A survey on the experience of 1125 physicians in Spain.

BACKGROUND: We explored the experience of clinicians from the Spanish Society of Anesthesiology (SEDAR) in airway management of COVID-19 patients. METHODS: An software-based survey including a 32-item questionnaire was conducted from April 18 to May 17, 2020. Participants who have been involved in tracheal intubations in patients with suspected or confirmed COVID-19 infection were included anonymously after obtaining their informed consent. The primary outcome was the preferred airway device for tracheal intubation. Secondary outcomes included the variations in clinical practice including the preferred video laryngoscope, plans for difficult airway management, and personal protective equipment. RESULTS: 1125 physicians completed the questionnaire with a response rate of 40,9%. Most participants worked in public hospitals and were anesthesiologists. The preferred device for intubation was the video laryngoscope (5.1/6), with the type of device in decreasing order as follows: Glidescope, C-MAC, Airtraq, McGrath and King Vision. The most frequently used device for intubation was the video laryngoscope (70,5%), using them in descending order as follow: the Airtraq, C-MAC, Glidescope, McGrath and King Vision. Discomfort of intubating wearing personal protective equipment and the frequency of breaching a security step was statistically significant, increasing the risk of cross infection between patients and healthcare workers. The opinion of senior doctors differed from younger physicians in the type of video-laryngoscope used, the number of experts involved in tracheal intubation and the reason that caused more stress during the airway management. CONCLUSIONS: Most physicians preferred using a video-laryngoscope with remote monitor and disposable Macintosh blade, using the Frova guide.

Intubation in the Intensive Care Unit: C-MAC video laryngoscope versus Macintosh laryngoscope.

PURPOSE: Various modifications of the Macintosh blade and direct laryngoscopy have been incorporated into practice to improve the intubation success rate and avoid complications while ensuring patient safety. This study evaluates the usefulness of two different direct laryngoscopy methods used by operators with various level of experience in the Intensive Care Unit. MATERIAL AND METHODS: In a single centre prospective study, C-MAC and Macintosh laryngoscopes were compared in terms of laryngoscopy and intubation outcomes such as glottic visualization, number of intubation attempts, intubation success and satisfaction score. RESULTS: During the one-year study period, 263 patients were evaluated and data of 218 patients were analyzed. The rate of successful first attempt intubation was higher in the video laryngoscope group (VL) (84% vs 57%; P<0.001). A significantly greater number of patients in the Macintosh laryngoscopy group had difficult visualization of the glottis in terms of the modified Cormack and Lehane classification and Percentage of Glottic Opening scale. CONCLUSION: The use of video laryngoscope for intubation in ICU settings results in better visualization of the glottis and a higher incidence of successful intubation attempts.

[Use of video laryngoscope for tracheal intubation in patient with oral cavity mass: case report]. / Uso de videolaringoscópio para intubação traqueal em paciente com massa tumoral na cavidade oral: relato de caso.

BACKGROUND AND OBJECTIVES: When planning the management of a predicted difficult airway, it is important to determine which strategy will be followed. Video laryngoscopy is a major option in scenarios with factors suggesting difficult airway access. It is also indicated in rescue situations, when there is tracheal intubation failure with direct laryngoscopy. The objective of the present report was to show the efficacy of using the video laryngoscope as the first device for a patient with a large tumor that occupied almost the entire anterior portion of the oral cavity. CASE REPORT: 85 year-old male patient, 162 cm, 70 kg, physical status ASA II, Mallampati IV classification, was scheduled for resection of an angiosarcoma located in the right maxillary sinus that invaded much of the hard palate and the upper portion of the oropharynx. He was conscious and oriented, with normal blood pressure, heart and respiratory rates and, despite the large tumor in the oral cavity; he showed no signs of respiratory failure or airway obstruction. After intravenous cannulation and monitoring, sedation was performed with 1mg of intravenous midazolam, and a nasal cannula was placed to provide oxygen, with a flow of 2 L.min-1. Then, the target-controlled infusion of remifentanil with an effect site concentration of 2 ng.mL-1 was initiated, according to Minto's pharmacokinetic model. Ventilation was maintained spontaneously during airway handling. A trans cricothyroid block was performed, with 8 mL of 1% lidocaine solution injected into the tracheal lumen. Slight bleeding did not prevent the use of an optical method for performing tracheal intubation. The entire oral cavity was sprayed with 1% lidocaine. The McGraph video laryngoscope with the difficult intubation blade was used, and an armored tube with a guide wire inside was used for tracheal intubation, performed on the first attempt with appropriate glottis visualization. CONCLUSION: The video laryngoscope occupies a prominent position in cases in which access to the airway is difficult. In the present case it was useful. It can be used as first choice or as a rescue technique. The video laryngoscope is an appropriate alternative and should be available for facing the ever-challenging difficult airway patient.

Difficult airway management in a patient with Treacher Collins syndrome using two-part surgery. / Manejo de la vía aérea en una paciente con síndrome de Treacher Collins en 2 tiempos quirúrgicos.

Treacher Collins syndrome (TCS), Franceschetti-Zwahlen-Klein, or mandibulofacial dysostosis, is a rare disorder of craniofacial development (incidence of approximately 1:50.000 live births). TCS is relevant to the anaesthetist because it can cause difficulties in airway management. A case report is presented of a 24 year-old woman who was referred to our institution for facial reconstruction surgery in two stages. In both surgeries Airtraq™ was essential for airway management. By presenting this case, it is intended to show that planning, communication and teamwork are indispensable for patient safety.

Comparison between stylet and bougie with the C-MAC D-blade in cervical simulated immobility. A prospective randomized controlled trial

Introduction The C-MAC D-blade was designed for difficult airway intubation scenarios. To facilítate easier and faster endotracheal intubation in the laryngoscopy paradox, an introducer is preferred. Hence, we decided to conduct a study to compare the 60° angled C-MAC stylet and the gum elastic bougie as aids to intubation while using the C-MAC D-blade laryngoscope in a simulated difficult airway setting. Objective To compare the ease of oral intubation with the use of the C-MAC stylet (60° angled stylet) versus intubation performed over a bougie inserted using the C-MAC D-blade guidance in patients with simulated restricted cervical mobility. Method Prospective, randomized controlled single-center study. Intubation using the C-MAC D-blade laryngoscope was performed in 48 surgical patients randomly assigned to 2 groups of 24 each: Stylet group, Group S (using 60° angled stylet) and Bougie group, Group B (using bougie) after providing manual in-line stabilization to restrict cervical mobility. The Mann-Whitney U test and the Chi square test were used as applicable. Results The use of stylet resulted in easier (Group S 75% vs. Group B 16.7%) and faster (Group S 26.83 ± 8.61s vs. Group B 47.18 ± 16.46s) intubation with fewer attempts compared to group B. Both groups experienced a similar hemodynamic stress response to intubation. Conclusions The 60° angled C-MAC Stylet is a more effective and time-saving intubation aid with C-MAC D-blade compared to bougie.

Introducción: El videolaringoscopio C-MAC D-blade se diseñó para los casos de intubación de la vía aérea difícil. Para facilitar una intubación más rápida y sencilla en la paradoja de la laringoscopía se prefiere un introductor. Por tanto, decidimos realizar un estudio para comparar el estilete de 60° C-MAC y el bougie elástico de goma como ayudas para la intubación utilizando el laringoscopio C-MAC D-blade en una situación simulada de vía aérea difícil. Objetivo: Comparar la facilidad de intubación oral mediante el uso del estilete del C-MAC (estilete angulado de 60°) con la intubación realizada sobre un bougie insertado con la guía del C-MAC D0-blade en pacientes con restricción simulada de la movilidad cervical. Métodos: Estudio prospectivo, aleatorizado y controlado realizado en un solo centro. Se realizó intubación utilizando el laringoscopio C-MAC D-blade D en 48 pacientes quirúrgicos asignados aleatoriamente a 2 grupos de 24 cada uno: grupo de estilete, grupo S (con el estilete angulado de 60°) y el grupo de bougie o grupo B (con bougie) después de establecer una estabilización manual del eje para restringir la movilidad cervical. Se aplicaron las pruebas U de Mann-Whitney U y de Chi cuadrado según correspondiera. Resultados: Con el estilete fue más fácil (Grupo S 75% vs. Grupo B 16.7%) y más rápida (Grupo S 26.83 ± 8.61s vs. Grupo B 47.18 ± 16.46s) la intubación, requiriéndose un menor número de intentos en comparación con el Grupo B. Los dos grupos experimentaron un estrés hemodinámico similar en respuesta a la intubación. Conclusiones: El estilete angulado de 60° C-MAC es una ayuda más efectiva y ahorra más tiempo con el C-MAC D-blade en comparación con el bougie.

Can videolaryngoscopy be a first option in a patient with laryngeal amyloidosis? / ¿Puede la videolaringoscopia ser una primera opción en paciente con amiloidosis laríngea?

Amyloidosis is a term that involves a group of diseases characterised by deposition of extracellular monoclonal light-chain fibrillar immunoglobulin aggregates in the body, including many organs, with the larynx among them. A case is presented of a 78 year-old man who was referred to our institution for strangulated umbilical hernia treatment. He suffered from progressive hoarseness and dysphagia for 5months. He had a history of primary laryngeal amyloidosis. Awake intubation was performed successful with the King Vision® video-laryngoscopy. Sedation was achieved using a remifentanil infusion and midazolam. Haemorrhagic lesions are caused by deposition of amyloid in and around vessels, resulting in increased vascular fragility. Therefore, anaesthetists should take care in intubating the tracheas of these patients.

[Comparison of different methods of nasogastric tube insertion in anesthetized and intubated patients]. / Comparação de diferentes métodos de inserção de sonda nasogástrica em pacientes anestesiados e intubados.

BACKGROUND: Nasogastric tube insertion may be difficult in anesthetized and intubated patients with head in the neutral position. Several techniques are available for the successful insertion of nasogastric tube. The primary aim of this study was to investigate the difference in the first attempt success rate of different techniques for insertion of nasogastric tube. Secondary aim was to investigate the difference of the duration of insertion using the selected technique, complications during insertion such as kinking and mucosal bleeding. MATERIAL AND METHODS: 200 adult patients, who received general anesthesia for elective abdominal surgeries that required nasogastric tube insertion, were randomized into four groups: Conventional group (Group C), head in the lateral position group (Group L), endotracheal tube assisted group (Group ET) and McGrath video laryngoscope group (Group MG). Success rates, duration of insertion and complications were noted. RESULTS: Success rates of nasogastric tube insertion in first attempt and overall were lower in Group C than Group ET and Group MG. Mean duration and total time for successful insertion of NG tube in first attempt were significantly longer in Group ET. Kinking was higher in Group C. Mucosal bleeding was statistically lower in Group MG. CONCLUSION: Use of video laryngoscope and endotracheal tube assistance during NG tube insertion compared with conventional technique increase the success rate and reduce the kinking in anesthetized and intubated adult patients. Use of video laryngoscope during nasogastric tube insertion compared to other techniques reduces the mucosal bleeding in anesthetized and intubated adult patients.

[Comparison of different stylets used for intubation with the C-MAC D-Blade® Videolaryngoscope: a randomized controlled study]. / Comparação de diferentes estiletes usados para intubação com o videolaringoscópio C­MAC D­Blade®: um estudo randômico e controlado.

OBJECTIVE: The angle of the C-MAC D-Blade® videolaryngoscope, which is used for difficult airway interventions, is not compatible with routinely used endotracheal tubes. METHODS: A prospective randomized crossover study was performed comparing five intubation methods for use with standardized airways, including using different stylets or no stylet: Group HS, hockey-stick stylet; Group DS, D-blade type stylet; Group CS, CoPilot® videolaryngoscope rigid stylet®; Group GEB, gum elastic bougie; and Group NS, no stylet. A manikin was used to simulate difficult intubation with a Storz C-MAC D-Blade® videolaryngoscope. The duration of each intubation stage was evaluated. RESULTS: Participants in this study (33 anesthesiology residents and 20 anesthesiology experts) completed a total of 265 intubations. The number of attempts made using no stylet was significantly greater than those made for the other groups (p<0.05 for group NS- group GEB, group NS- group DS, group NS- group CS and group NS- group HS). The duration to pass the vocal cords significantly differed among all groups (p<0.001). The total intubation duration was shortest when using D-blade stylet, CoPilot stylet and hockey stick stylet. Although no difference was observed between stylet groups, a significant difference was found between each of these three and no stylet and gum elastic bougie (p<0.05 and p<0.001, respectively). CONCLUSION: Use of the correct stylet leads to a more efficient use of the Storz C-MAC D-Blade®. In our study, the use of the D-blade stylet, the CoPilot stylet and the hockey stick stylet provided quicker intubation, allowed easier passage of the vocal cords, and decreased the total intubation duration. To confirm the findings of our study, randomized controlled human studies are needed.

Use of King Vision® videolaryngoscope in an unanticipated difficult airway in an adult patient with giant vallecular cyst, a case report. / Uso del videolaringoscopio King Vision® en una vía aérea difícil no esperada por un quiste vallecular gigante en un adulto, a propósito de un caso.

Laryngeal cysts are largely asymptomatic and typically described in the context of incidental discovery on routine laryngoscopy. These cysts, in adults are even rarer and can have catastrophic consequences in an anaesthetized patient if airway management is inappropriate. We describe a case of difficult endotracheal intubation and the treatment of an adult patient with an asymptomatic, giant vallecular cyst that was discovered during rapid-sequence induction of general anesthesia in urgent surgery. In conclusion, vallecular cysts can cause extreme problems in securing the airway. It is important to avoid complications associated with repeated attempts at intubation, airway loss, or cyst rupture causing difficulty visualizing vocal cords and aspiration. The use of King Vision® videolaryngoscope is a good alternative in these cases. Close attention to logistics and the immediate availability of an otolaryngologist is vital.

Comparing insertion characteristics on nasogastric tube placement by using GlideScope™ visualization vs. MacIntosh laryngoscope assistance in anaesthetized and intubated patients.

BACKGROUND AND OBJECTIVE: This was a prospective, randomized clinical study to compare the success rate of nasogastric tube insertion by using GlideScope™ visualization versus direct MacIntosh laryngoscope assistance in anesthetized and intubated patients. METHODS: Ninety-six ASA I or II patients, aged 18-70 years were recruited and randomized into two groups using either technique. The time taken from insertion of the nasogastric tube from the nostril until the calculated length of tube had been inserted was recorded. The success rate of nasogastric tube insertion was evaluated in terms of successful insertion in the first attempt. Complications associated with the insertion techniques were recorded. RESULTS: The results showed success rates of 74.5% in the GlideScope™ Group as compared to 58.3% in the MacIntosh Group (p=0.10). For the failed attempts, the nasogastric tube was successfully inserted in all cases using rescue techniques. The duration taken in the first attempt for both techniques was not statistically significant; Group A was 17.2±9.3s as compared to Group B, with a duration of 18.9±13.0s (p=0.57). A total of 33 patients developed complications during insertion of the nasogastric tube, 39.4% in Group A and 60.6% in Group B (p=0.15). The most common complications, which occurred, were coiling, followed by bleeding and kinking. CONCLUSION: This study showed that using the GlideScope™ to facilitate nasogastric tube insertion was comparable to the use of the MacIntosh laryngoscope in terms of successful rate of insertion and complications.

[Outdoor performance of different videolaryngoscopes on a glacier: a manikin study]. / Rendimiento de diferentes tipos de videolaringoscopios en un glaciar al aire libre: estudio con maniquíes.

OBJECTIVES: Little information about the performance of videolaryngoscopes outdoors is available. We aimed to test the hypothesis that a Macintosh direct laryngoscope would perform less well than videolaryngoscopes under difficult environmental conditions (high-altitude glacier, sun-reflecting snow). MATERIAL AND METHODS: After local research ethics committee approval, this randomized controlled trial enrolled 20 physicians who intubated manikins with limited cervical extension mouth opening under 5 conditions: 1) in hospitals (indoors), 2) indoors at a high altitude, 3) outdoors on a glacier in sunlight without sunglasses, 4) outdoors on a glacier with sunglasses, and 5) outdoors on a glacier with the physician and manikin covered with a blanket. The following devices were compared to the Macintosh laryngoscope, McGrath, Airtraq-SP, GlideScope, KingVision, C-MAC-D-Blade, AP Advance Difficult Airway Blade and Bonfils. The main outcome was first-attempt intubation success; secondary outcomes were intubation time, visibility on the screen, and view of the glottis. RESULTS: The best intubation success rates were observed indoors asnd on the glacier under a blanket. The Macintosh performed better than the videolaryngoscopes under bright sunlight. We observed significant differences in the performance of devices with built-in screens under varying conditions. Wearing sunglasses improved performance with some but not all devices. Intubation times differed significantly between devices, regardless of the environmental condition (P<0.01). Screen visibility differed significantly between conditions and devices. CONCLUSION: Successful intubation with videolaryngoscopes is less likely under bright sunlight conditions. The Macintosh laryngoscope performs better than videolaryngoscopes. Covering the heads of both the physician and the patient with a dark blanket sufficiently overcomes the detrimental effects of sunlight during intubation.

OBJETIVO: Existe muy poca información sobre la realización de videolaringoscopias al aire libre. Investigamos el rendimiento de una variedad de dispositivos de intubación en comparación con la laringoscopia directa y bajo condiciones ambientales difíciles (glaciar de gran altitud, nieve con efecto reflectante). METODO: Tras la aprobación por el comité local de ética, este estudio aleatorizó a 20 médicos que intubaron maniquíes con limitación en la apertura bucal y en la extensión cervical, bajo cinco circunstancias: 1) en el interior de hospitales, 2) en interiores a la altitud del glaciar, 3) en un glaciar a plena luz solar, 4) en un glaciar con gafas de sol, y 5) en un glaciar, con el médico y el maniquí cubiertos por una manta. Los dispositivos evaluados fueron: laringoscopio Macintosh y los videolaringoscopios McGrath, Airtraq-SP, GlideScope, KingVision, C-MAC-D-blade, APAdvancedifficult- airway-blade y Bonfils. El resultado principal a analizar fue el éxito de intubación al primer intento; y los resultados secundarios el tiempo de intubación, la visibilidad de de la glotis en la pantalla. RESULTADOS: Se observó un mayor índice de éxito de intubación en el interior, así como al aire libre en el glaciar cuando se cubría con una manta. El rendimiento a plena luz del día del Macintosh fue superior a la de los videolaringoscopios. En los dispositivos con pantallas incorporadas se percibieron diferencias significativas en condiciones ambientales cambiantes. El uso de gafas de sol mejoró el rendimiento de algunos dispositivos, pero no de todos. El tiempo de intubación difirió sustancialmente entre los dispositivos, independientemente de las condiciones ambientales (p < 0,01). La calidad de visibilidad de la pantalla varió significativamente según las condiciones y los dispositivos. CONCLUSIONES: El laringoscopio Macintosh se comporta mejor que los videolaringoscopios. Las posibilidades de éxito en la intubación con videolaringoscopios es menor en condiciones de luz solar brillante. Cubrir la cabeza con una manta oscura bloquea suficientemente los efectos perjudiciales de la luz solar durante la intubación a pleno sol.

Simulación de intubación pediátrica con videolaringoscopio de bajo costo en contexto de pandemia por COVID-19 / Simulation of pediatric intubation using a low-cost videolaryngoscope in the setting of the COVID-19 pandemic

En pacientes con infección por SARS-CoV-2 la intubación endotraqueal es un procedimiento con riesgo elevado de contagio. La videolaringoscopia complementa la protección del profesional, pero los videolaringoscopios comerciales son caros y no siempre están disponibles en las terapias intensivas pediátricas argentinas. El objetivo fue describir la práctica de intubación en un modelo de cabeza de simulación de lactante con un videolaringoscopio artesanal de bajo costo.Quince pediatras sin experiencia previa con el dispositivo participaron de una práctica de intubación en una cabeza de simulación con un videolaringoscopio artesanal. El tiempo promedio del primer intento fue de 116,4 segundos (intervalo de confianza del 95 % [IC95 %]: 84,8-148,0) y, el del siguiente fue de 44,2 segundos (IC95 %: 27,7­60,6). El tiempo disminuyó de forma significativa en el segundo intento (p : 0,0001). El dispositivo permitió la intubación exitosa en todos los intentos acortando la duración del procedimiento en la segunda práctica

In patients with SARS-CoV-2 infection, endotracheal intubation is a procedure with a high risk for transmission. A videolaryngoscopy is a supplementary level of health care provider protection, but commercial videolaryngoscopes are expensive and not always available in pediatric intensive care units in Argentina. Our objective was to describe intubation practice using an infant head mannequin with a low-cost, handcrafted videolaryngoscope.Fifteen pediatricians with no prior experience using the device participated in an intubation practice in a head mannequin with a handcrafted videolaryngoscope. The average time for the first attempt was 116.4 seconds (95 % confidence interval [CI]: 84.8-148.0) and, for the second one, 44.2 seconds (95 % CI: 27.7-60.6). Time decreased significantly for the second attempt (p: 0.0001).A successful intubation was achieved with the device in all attempts, and the procedure duration decreased with the second practice

Assessment of TruviewPCD videolaryngoscope for intubation in children. / Evaluación del videolaringoscopio TruviewPCD para la intubación de niños.

OBJECTIVE: The aim of this observational prospective study was to evaluate the usefulness of TruviewPCD for tracheal intubation in clinical practice, and to provide data for future studies. MATERIAL AND METHOD: A study was conducted on 86 consecutive children undergoing ear, nose and throat (ENT) or paediatric procedures under general anaesthesia with tracheal intubation. Children with two or more difficult airway criteria were excluded. A descriptive statistical analysis was performed. RESULTS: Eighty-three patients were successfully intubated with TruviewPCD. Demographic data: Age 4.9 (2.8) years, weight 19.5 (7.7)kg. Seventy-nine children needed one attempt and four required two attempts at intubation. Time for glottis view and tracheal intubation was 10.8 (5.6) and 30 [27.9-37] seconds, respectively. Eighty-one patients were classified as easy or very easy to intubate, and only two cases were considered difficult. No significant complications were registered. CONCLUSIONS: TruviewPCD is a good device for paediatric airway management. It would be interesting to have an intermediate blade between size 1 and 2, as the difference between both is too wide.

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.

Manejo anestésico de resección de quiste de vallécula en neonato. A propósito de un caso / Anesthetic management of vallecular cyst resection in neonate. A case report

Difficult airway management is one of the most important challenges an anesthesiologist faces. It is due to the high morbidity and mortality that it entails. The challenge is even greater if the patient is a newborn. For this reason, we should have different strategies that allow us to anticipate and treat possible complications derived from the procedure. In this case, we present a newborn with vallecular cyst and respiratory distress who is admitted for cyst resection. The gold-standard in anticipated difficult airway management is the fibrobronchoscope. We decided to perform an alternative management by means of orotracheal intubation with videolaryngoscope (Glydescope®) in spontaneous ventilation

El manejo de una vía aérea difícil es uno de los retos más importantes a los que puede enfrentarse un anestesiólogo debido a la elevada morbimortalidad que conlleva. El reto aún es mayor si el paciente es un neonato. Por este motivo, debemos contar con diferentes estrategias que permitan anticipar y poder tratar las posibles complicaciones derivadas del procedimiento. En este caso, presentamos un neonato con quiste de vallécula con clínica de trabajo respiratorio que es admitido para cirugía de exéresis del quiste. El gold standard en el manejo de una vía aérea difícil conocida es el fibrobroncoscopio. Nosotros decidimos realizar un manejo anestésico alternativo mediante intubación orotraqueal con videolaringoscopio (Glydescope®) en ventilación espontánea.

[Effectiveness of the GlideScope video laryngoscope in a case of unexpected difficult airway due to lingual tonsil hypertrophy]. / Eficacia del videolaringoscopio GlideScope en un caso de vía aérea difícil imprevista por hipertrofia de la amígdala lingual.

Lingual tonsil hypertrophy can cause varying degrees of airway obstruction and is considered a risk factor for difficult mask ventilation and tracheal intubation. We report a case of unexpected difficult airway in a patient with unknown lingual tonsil hypertrophy that was solved with the use of the GlideScope video laryngoscope.
