A study published inĀ Anesthesiology found thatĀ video laryngoscopy was superior to other methods of attempted intubation, including flexible fiberoptic, lighted stylet, and supraglottic airway in a retrospective analysis of 346,861 anesthesia cases that involved attempted tracheal intubation.

The study’s main take-home message was that video laryngoscopy had the highest intubation success rate (92%), with the GlideScope (Verathon; Bothell, Washington) the most commonly used video laryngoscope device (89% of the time). The intubation success rate for rescue was 78% for both the supraglottic airway conduit and flexible bronchoscopic intubation, followed by 77% for lighted stylet and 67% for optical stylet.
