Question and Methods: Authors aimed to determine if video laryngoscopy improves rates of first pass success compared to direct laryngoscopy. They performed a pragmatic, multicenter, unblinded randomized parallel-group trial.
Findings: 85.1% first pass success with video laryngoscopy and 70.8% with direct laryngoscopy. No difference in severe complications or safety outcomes.
Limitations: Limitations of this study include the use of a surrogate primary outcome, and the treating clinician’s ability to choose not to enroll a patient in the study (determined that one method vs the other was either necessary or contraindicated).
Interpretation: Video laryngoscopy should likely be used as the preferred intubating method as it has highest first pass success, although this study did not show any benefit in rates of complications, and this may risk downstream effects on skill attrition for direct laryngoscopy.
