Universal videolaryngoscopy for tracheal intubation in the operating theatre: A prospective non‐randomised clinical trial
Primary resultResult — go to the resultAbsolute difference 12% 95% CI 9.8–14.1Authors' conclusion
In a real-world operating theatre setting, universal videolaryngoscopy was effective at increasing the rate of easy tracheal intubation and successful first-attempt tracheal intubation, while reducing the incidence of difficult laryngoscopy and complications related to tracheal intubation.
Study context
- Population
- Patients undergoing tracheal intubation in the operating theatre, real-world setting
- Participants
- 5,135 patients
- Comparison
- Interventional phase vs Non-interventional phase
- Interventional phasen = 2,567
- Non-interventional phasen = 2,568reference
- Primary endpoint
- Easy tracheal intubation (composite:
- First-attempt success
- Easy laryngoscopic view
- No need for adjunct airway devices)
Methodological detailsquasi-experimental, multicentre, before-after (non-interventional vs interventional phase)
- Quasi-experimental
- Multicentre
- Before-after (non-interventional vs interventional phase)
