Learning tracheal intubation with a hyperangulated videolaryngoscopy blade: sub‐analysis of a randomised controlled trial
Authors' conclusion
Clinicians experienced in tracheal intubation with direct laryngoscopy but unfamiliar with hyperangulated-blade videolaryngoscopy can achieve proficiency after approximately 12 attempts.
Study context
- Population
- Clinicians familiar with direct laryngoscopy and Macintosh-blade videolaryngoscopy but inexperienced with hyperangulated videolaryngoscopy
- Participants
- 223 participants · 4,312 procedures
- Comparison
- Consultants vs Certified registered nurse anaesthetists vs Student registered nurse anaesthetists vs Fellows vs Residents
- Consultantsn = 25
- Certified registered nurse anaesthetistsn = 35
- Student registered nurse anaesthetistsn = 36
- Fellowsn = 46
- Residentsn = 81
- Primary endpoint
- First-attempt tracheal intubation success (cumulative sum learning curves; acceptable success rate 85%, unacceptable 70%)
Methodological detailsplanned sub-analysis, cumulative sum learning curves
- Planned sub-analysis
- Cumulative sum learning curves

Further findings
