Neuraxial anesthetic failures for postpartum tubal ligation after vaginal delivery: a single center retrospective cohort study (2013–2023)
Authors' conclusion
Neuraxial anesthesia failure rates were similar to previously described rates of failure, with no difference between spinal anesthetics and labor epidural catheter reactivations.
Study context
- Population
- Patients undergoing postpartum tubal ligation after vaginal delivery, single centre, 2013–2023
- Participants
- 363 patients
- Exposure
- Labor epidural catheter reactivation vs de novo spinal anesthesia
- Outcome
- Failed neuraxial anesthesia rate (second neuraxial procedure, moderate-to-deep sedation, or conversion to GA)
Methodological detailssingle-centre
