A Prospective, Feasibility Assessment of a Novel, Disposable Video Laryngoscope With Special Operations Medical Personnel in a Mobile Helicopter Simulation Setting

Abstract

Background: Video laryngoscopy (VL) is shown to improve first-pass success rates and decrease complications in intubations, especially in novice proceduralists. However, the currently fielded VL devices are cost-prohibitive for dispersion across the battlespace. The novel i-view VL is a low-cost, disposable VL device that may serve as a potential solution. We sought to perform end-user performance testing and solicit feedback. Methods: We prospectively enrolled Special Operations flight medics with the 160th Special Operations Aviation Regiment at Hunter Army Airfield, Savannah, Georgia. We asked them to perform an intubation using a synthetic cadaver model while in a mobile helicopter simulation setting. We surveyed their feedback afterward. Results: The median age of participants was 30 and all were male. Of those, 60% reported previous combat deployments, with a median of 20 months of deployment time. Of the 10, 90% were successful with intubation, with 60% on first-pass success with an average of 83 seconds time to intubation. Most had a grade 1 view. Most agreed or strongly agreed that it was easy to use (70%), with half (50%) reporting they would use it in the deployed setting. Several made comments about the screen not being bright enough and would prefer one with a rotating display. Conclusions: We found a high proportion of success for intubation in the mobile simulator and a high satisfaction rate for this device by Special Operations Forces medics.
