Flexible bronchoscopic intubation through a supraglottic airway device: An evaluation of consultant anaesthetist performance
Authors' conclusion
Consultant anaesthetists had a median global rating scale score of 29.7 when using a SAD as conduit for FBI. However, despite reporting high procedural confidence, at least one global rating scale domain was deemed 'not competent' in 30% of cases, which indicates a clear potential for improvement of skill competence among professionals.
Study context
- Population
- Adult patients undergoing flexible bronchoscopic intubation (FBI) under continuous ventilation through a second-generation supraglottic airway device (SAD) performed by consultant anaesthetists25 anaesthetists, 4 intubations each
- Participants
- 100 patients
- Outcome
- Objective Structured Assessment of Technical Skills-inspired global rating scale score
Methodological detailsvideo-recorded, three independent external assessors
- Video-recorded
- Three independent external assessors
Main finding
As reported in the abstract
OSATS-inspired global rating scale score, overall
Median global rating scale score (IQR 26.0-32.7; range 16.7-37.7)
29.7
Observational data: associations, not effects.
Further findings
Overall pass rate (average of assessors' score ≥3 in every domain)
- ≥1 global rating scale domain 'not competent' (scored <3), % of cases
- 30%
- Pass rate
- 70% (95% CI 60%-78%)
First vs fourth case of airway management
- Time to intubation: statistically significant difference
- P = 0.006
- Global rating scale score: no difference
- P = 0.018
- Self-reported confidence before the procedure: no difference
- P = 0.014
- Pass rate: no difference
- P = 0.109
- After adjusting for multiple testing
