Video Laryngoscopy vs. Direct Laryngoscopy

Tracheal intubation is a critical step in securing the patient's airway in a variety of emergent and non-emergent settings. Difficulties and complications may arise with this procedure, and alternative laryngoscopes that use video technology have been designed to improve visibility when airway difficulty is predicted or encountered. These devices may be flexible or rigid in design for the purpose of assisting in intubations, especially expected difficult intubations. Video laryngoscopes have been advertised as being able to reduce difficulty, failure, trauma and other complications compared with direct laryngoscopy. Rigid video laryngoscopy uses a blade to retract the soft tissues and transmits a video image to a screen attached to the end of the handle or to a monitor. This design enables a lighted view of the larynx without direct 'line of sight', and is also referred to as indirect laryngoscopy. In the Cochrane review discussed here,1 video laryngoscopy is compared to direct laryngoscopy in the tracheal intubation of adult patients. This article is protected by copyright.

Probably should actually just read the Cochrane review being discussed in this paper, published 2016:

Videolaryngoscopy versus direct laryngoscopy for adult patients requiring intubation. Lewis et al. PMID 27844477.
