Evaluation of induction practices for general anesthesia in patients with obesity: A French nationwide online survey
Authors' conclusion
This nationwide survey highlights substantial variability in anesthetic induction practices for patients with obesity, reflecting the absence of consensus.
Study context
- Population
- French anesthesiologists, May–December 2024, on induction of GA in patients with obesity652 analysed
- Participants
- 665 participants
- Exposure
- RSI vs conventional induction, as reported by participants
- Outcome
- Anesthetic induction practices in patients with obesity, and influence of BMI and obesity-related comorbidities on the decision for or against RSI
Methodological detailsnationwide, anonymous online declarative survey, standardized theoretical clinical scenarios
- Nationwide
- Anonymous online declarative survey
- Standardized theoretical clinical scenarios
Main finding
As reported in the abstract
- Would not perform RSI at BMI 43 kg/m²
- 57%
- Regarded BMI ≥40 kg/m² as appropriate threshold for RSI
- 33%
- Did not define any specific BMI threshold
- 24%
- Anesthesiologist experience associated with choice of induction sequence
- p = 0.003
Observational data: associations, not effects.
Further findings
NMBA dose calculation
- Used total body weight for non-depolarizing agents
- 28%
- Considerable heterogeneity
Apneic oxygenation
- Never used apneic oxygenation
- 32%
- Underused
