Video Laryngoscopy vs Direct Laryngoscopy for Endotracheal Intubation in the Operating Room: A Cluster Randomized Clinical Trial

In this study among adults having surgical procedures who required single-lumen endotracheal intubation for general anesthesia, hyperangulated video laryngoscopy decreased the number of attempts needed to achieve endotracheal intubation compared with direct laryngoscopy at a single academic medical center in the US.
Study context
- Population
- Adults ≥18 y having elective or emergent cardiac, thoracic or vascular surgery requiring single-lumen endotracheal intubation for GA, single US academic hospital
