Manejo de vía aérea en pacientes COVID-19: una encuesta sobre la experiencia de 1125 médicos en España

BACKGROUND: We explored the experience of clinicians from the Spanish Society of Anesthesiology 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 physicians. 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.
