Abstract

|
|
Objective: The purpose of this study was to determine the type of video laryngoscope training that is appropriate for emergency medical technicians (EMT) familiar with direct laryngoscopes, to prepare them for tracheal intubation while they are wearing personal protective equipment (PPE).
Methods: Thirty-eight healthy EMTs were recruited. The participants underwent two tests with four different laryngoscopes: Macintosh, McGrath, Pentax Airway Scope (PENTAX-AWS), and A-LRYNGO. The first test was conducted just after a lecture without any hands-on workshops. The second test was conducted after a hands-on workshop. In each test, we measured the time required for tracheal intubation, intubation success rate, etc., and asked all the participants to respond to a short questionnaire.
Results: The time to complete the insertion of the endotracheal tube with the Macintosh laryngoscope did not significantly change (P=0.098), but the rest of the outcomes significantly improved after the hands-on workshop (all P<0.05).
Despite the unfamiliarity of the practitioners with video laryngoscopes and their wearing PPE, intubation-related performances were good with the two-channel type video laryngoscopes after the hands-on workshop (all P<0.05).
Conclusion: In preparation for an infectious disease pandemic such as the coronavirus disease 2019 (COVID-19), it would be reasonable to train EMTs who would be wearing PPE on the procedure for intubating a trachea with a channeltype video laryngoscope.
