Anesthetic management of intrapartum cesarean deliveries with an in-situ epidural catheter during second-stage versus first-stage of labor: a single-center retrospective study (2022–2024)
Authors' conclusion
After propensity score matching, stage of labor at the time of procedure was not associated with increased intravenous adjunct use or general anesthesia conversion for intrapartum cesareans.
Study context
- Population
- Intrapartum cesareans with in-situ epidural catheters, single referral institution, 2022–202426% second stage
- Participants
- 968 participants
- Exposure
- Second-stage vs First-stage
- Outcome
- IV adjunct use and conversion to GA
Methodological detailsquasi-experimental, propensity score matched, single-centre
- Quasi-experimental
- Propensity score matched
- Single-centre
Main finding
As reported in the abstract
- Intraoperative IV adjunct use and conversion to GA comparable across stages and analgesia duration
- After propensity score matching
Observational data: associations, not effects.
Further findings
Obstetric outcomes and procedural times
- Second-stage cesareans mainly due to arrest of stage, with higher rates of uterine atony, PPH, hysterotomy extension, and longer procedural times
Analgesia duration
- Longer analgesia duration associated with increased operating-room preparation time, cesarean duration, and neuraxial replacement before procedure
