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

Educational suitability of endotracheal intubation using a video-laryngoscope / 한국의학교육

PURPOSE: The purpose of this study is to determine the educational suitability of the video-laryngoscope in teaching endotracheal intubation to students. METHODS: Medical students participated in a course on the use of a Macintosh direct laryngoscope and McGrath MAC videolaryngoscope for intubation. The course comprised a 1-hour lecture and 30 minutes of practice on a manikin. After the course, in each of the three simulated patient scenarios-normal airway, cervical spine fixation, and tongue edema-time to intubate, success rate, and chance of complications were measured. A questionnaire was administered before and after the course to determine the suitability of intubation by video-laryngoscope for a medical education course. Also, changes in the perception and stance on the video-laryngoscope were evaluated. RESULTS: Time to intubate decreased as attempts were repeated. The first-attempt success rate in the cervical spine fixation scenario was higher using the video-laryngoscope (p=0.028). Rates if tooth injury were lower in the cervical spine fixation (p=0.005) and tongue edema scenarios (p=0.021) using the video-laryngoscope. Based on the questionnaires, students responded positively with regard to their knowledge of the video-laryngoscope, its practical value, and its suitability for medical education (p<0.001). Also, the preference for the video-laryngoscope was greater (p=0.044). Students felt that repeated attempts and feedback on intubation were helpful. CONCLUSION: The students' evaluations and surveys showed positive results to intubation by video-laryngoscope. Thus, based on its suitability for medical education it is reasonable to consider learning intubation using the video-laryngoscope.
