Incidence of conversion to general anaesthesia and need for intravenous supplementation in parturients undergoing caesarean section under spinal anaesthesia: A retrospective observational study
Authors' conclusion
A small proportion of women required conversion to GA. This conversion occurred especially with emergency caesarean section and when low spinal bupivacaine doses were used.
Study context
- Population
- Women undergoing caesarean section under spinal anaesthesia (≥10 mg heavy bupivacaine and opioids), 1 January 2017 to 31 December 2020
- Outcome
- Rate of conversion from spinal anaesthesia to GA
Main finding
As reported in the abstract
Conversion to GA
Women requiring conversion to general anaesthesia (GA)
1.7%
Observational data: associations, not effects.
