Applied forces with direct versus indirect laryngoscopy in neonatal intubation: a randomized crossover mannequin study
Authors' conclusion
The lower force applied during videolaryngoscopy in a neonatal mannequin model suggests a possible benefit in reducing potential patient harm during intubation
Study context
- Population
- Neonatal/pediatric/anesthesiology consultants and residents intubating a neonatal mannequinconsultants and residents
- Participants
- 30 consultants
- Comparison
- Straight blade and hyperangulated videolaryngoscopy vs direct laryngoscopy
- Primary endpoint
- Maximum peak force applied during intubation
Methodological detailsmannequin study
- Mannequin study
Primary result
As reported in the abstract
Maximum peak force on the epiglottis
Secondary outcomes
Average peak force on the epiglottis
Average peak force on the epiglottis
- Differences significant between direct laryngoscopy and each videolaryngoscopy
Top 10th percentile forces on epiglottis and palate; median forces on palate
- Significant differences in top 10th percentile forces on epiglottis and palate, not in median forces on palate
Time to intubation and subjective workload
- Comparable with videolaryngoscopy vs direct laryngoscopy
