Abstract

Objective: To determine perinatal outcomes following uterine rupture during a trial of labor after one previous cesarean delivery (CD) at term.

Methods: A retrospective single-center study examining perinatal outcomes in women with term singleton pregnancies with one prior CD, who underwent a trial of labor after cesarean (TOLAC) and were diagnosed with uterine rupture, between 2011 and 2022. The primary outcome was a composite maternal outcome, and the secondary outcome was a composite neonatal outcome. Additionally, we compared perinatal outcomes between patients receiving oxytocin during labor with those who did not.

Results: Overall, 6873 women attempted a TOLAC, and 116 were diagnosed with uterine rupture. Among them, 63 (54.3%) met the inclusion criteria, and 18 (28%) had the maternal composite outcome, with no cases of maternal death. Sixteen cases (25.4%) had the composite neonatal outcome, with one case (1.6%) of perinatal death. No differences were noted between women receiving oxytocin and those not receiving oxytocin in the rates of maternal composite (35.7% vs 26.5%, P = 0.502, respectively) or neonatal composite outcomes (21.4% vs 26.5%, P = 0.699).

Conclusion: Uterine rupture during a TOLAC entails increased risk for myriad adverse outcomes for the mother and neonate, though possibly more favorable than previously described. Oxytocin use does not affect these risks.
