Main finding
As reported in the abstract
Insertion time and ability to ventilate
Ability to ventilate after insertion, %
100
95% CI 96.7–100
Observational data: associations, not effects.
Secondary outcomes
≥1 manoeuvre required to assist insertion
- Cases requiring ≥1 manoeuvre, %
- 60.3 (95% CI 50.6-69.5)
Ease of insertion score (5-point scale)
- Median ease of insertion score (2-5[3-5])
- 4
Adequacy of ventilation score (5-point scale)
- Median adequacy of ventilation score (5-5[4-5])
- 5
First-time insertion failure
- First-time insertion failure rate
- 9.9% (95% CI 5.1-17.0%)
Safety
Patient harm, particularly desaturation
- No episodes of patient harm recorded
