A study led by Vanderbilt University Medical Center found that the use of a video laryngoscope increased the success of intubation on the first attempt.
Prehospital cricothyrotomies in a helicopter emergency medical service: analysis of 19,382 dispatches
Creating a patent airway by cricothyrotomy is the ultimate maneuver to allow oxygenation (and ventilation) of the patient. Given the rarity of airway management catastrophes necessitating cricothyrotomy, sufficiently sized prospective randomized trials are difficult to perform. Our Helicopter Emergency Medical Service (HEMS) documents all cases electronically, allowing a retrospective analysis of a larger database for all cases of prehospital cricothyrotomy.
