Failure of neuraxial anesthesia for postpartum tubal ligation: a single-centre retrospective cohort study
Authors' conclusion
Patients who underwent postpartum tubal ligation under single-injection spinal or combined spinal epidural anesthesia had a neuraxial failure rate of 11.5%. Time from spinal placement to skin incision and time from skin incision to wound closure were independently associated with neuraxial anesthesia failure.
