Previous studies reported that intubation attempts were prolonged, and incidence of esophageal intubation was increased with conventional Macintosh laryngoscope (McL), while wearing CBRN-PPE. Pentax-AWS (AWS), a recently introduced portable video laryngoscope, was compared with the McL to test its utility for tracheal intubation while wearing CBRN-PPE. Methods 31 participants performed unsuited and suited intubations on an advanced life support simulator. The sequence of intubating devices and PPE wearing were randomised. Time to complete tracheal intubation (primary end point), time to see the vocal cords, overall success rate, percentage of glottic opening, dental compression and ease of intubation were measured. Results Suited intubations required significantly longer time to complete intubation than unsuited intubations, in both McL and AWS (22.2 vs 26.4 s, 14.2 vs 18.2 s, respectively). However, suited AWS intubations required shorter time to complete tracheal intubation than unsuited McL intubations (18.2 vs 22.2 s). In secondary outcomes, moreover, suited intubations using the AWS compared favourably with unsuited intubations using the McL. Conclusions Although the CBRN-PPE adversely affected time required to complete tracheal intubation with the AWS, suited intubations using the AWS were even superior to unsuited intubations using the McL. The AWS should be a promising device to perform tracheal intubation while wearing the CBRN-PPE.}, issn = {1472-0205}, URL = {https://emj.bmj.com/content/30/7/527}, eprint = {https://emj.bmj.com/content/30/7/527.full.pdf}, journal = {Emergency Medicine Journal} }
