Assessment of Prehospital Tracheal Intubation Technique Using Initial Direct Laryngoscopy During Videolaryngoscopy: Randomized Controlled Simulated Trial

Tracheal intubation using videolaryngoscopy may be required in the prehospital setting, where airway management presents unique technical and logistical challenges. Intubation may be hard because novice providers performing videolaryngoscopy may only look at the screen and only obtain a two-dimensional representation of the patient's airways. By directly visualizing the airways, these providers may obtain a better 3D apprehension and an improved mental visualization of the patient's anatomy. We aim to compare the impact of a freely realized videolaryngoscopy sequence with a sequence consisting in direct visualization of the airway followed by videolaryngoscopy ("Direct Laryngoscopy-to-VideoLaryngoscopy sequence" or "DL-VL sequence") on time to intubation among novice providers.
