Airway management for one lung ventilation during COVID-19 pandemic: a survey within Italian anesthesiologists

Background: Airway management for thoracic surgery represents a high risk setting for SARS-CoV-2 infection diffusion due to complex and invasive airway instrumentation and techniques. Results: An 18-item questionnaire was submitted to the 56 members of the Thoracic subcommittee of the SIAARTI Cardio-Thoraco-Vascular Research Group to provide a snapshot of current situation and national variability of devices and procedures for airway management during the COVID-19 pandemic. The response rate was 64%. Eighty-three percent of anesthetists declared that they modified their airway management strategies. The Hospital Management considered necessary to provide a complete level 3 personal protective equipment for thoracic anesthetists only in 47% of cases. Double-lumen tube and bronchial blocker were preferred by 53% and 22% of responders to achieve one-lung ventilation respectively. Over 90% of responders considered the videolaryngoscope with separate screen and rapid sequence induction/intubation useful to minimize the infection risk. Thirty-nine percent of participants considered mandatory the bronchoscopic check of airway devices. Vivasight-DL was considered comfortable by more than 50% of responders while protective box and plastic drape were judged as uncomfortable by most of anesthetists. Conclusions: The survey reveals many changes in the clinical practice due to SARS-CoV-2 outbreak. A certain diffusion of new devices such as the VivaSight-DL and barrier enclosure systems emerged too. Finally, we found that most of Italian hospitals did not recognize thoracic anesthesia as a high-risk specialty for risk of virus diffusion.
