ObjectiveSince the introduction of video laryngoscopy (VL) as a technique for orotracheal intubation, its use has become widespread among prehospital providers. However, little information is available about the efficacy and success of VL compared with direct laryngoscopy (DL) in the helicopter emergency medical services (HEMS) setting. The objective of this study was to investigate whether VL or DL increased successful first-pass orotracheal intubations and overall intubation success by HEMS providers.DesignA retrospective chart review was performed on adults intubated by a HEMS program from January 2015 to July 2017. All orotracheal intubations with at least 1 attempt were included. Excluded were emergent cricothyrotomies, nonintubated patients, and those intubated before HEMS care.ResultsDL accounted for 21 intubations, whereas VL was used for 150 intubations. Nineteen of 21 (90.5%) DL intubations were successful on first pass, whereas 127 of 150 (84.7%) VL intubations were successful on first pass. The overall success rate was 90.5% for DL and 92.7% for VL. For both first-pass and overall success rates, the differences between modalities were not statistically significant. DL and VL had nearly identical complication rates, with hypoxia being the primary complication in both groups.ConclusionNo statistically significant difference was found in the first-pass rate, the overall success rate, or complications between DL and VL.Copyright © 2021 Air Medical Journal Associates.
