Morbidity associated with planned cesarean deliveries performed before the scheduled date: A cohort study

Résumé

Objective: Women with planned cesareans can require delivery before the scheduled date. However, data describing the morbidity associated with planned cesarean deliveries performed before the originally scheduled date is lacking. The objective of this study was to compare the morbidity associated with planned cesarean delivery performed before compared with on the scheduled date. Study design: This retrospective single-center cohort study included all 3595 women with singleton pregnancies and cesarean deliveries after 36+6 weeks. All cases were reviewed individually to identify the initial intended mode of delivery, determined before 37 weeks. We excluded the 2145 (59.7%) unplanned cesareans initially planned as vaginal deliveries. Finally, the analysis included 1450 women with planned cesareans: 1232 (85.0%) performed as scheduled, and 218 (15.0%) before that date. The composite outcomes of maternal morbidity was one or more of the morbidity measures, including surgical complications, postpartum hemorrhage, infection and thrombo-embolism. Neonatal morbidity measures included 5 min Apgar score < 7, arterial cord blood pH < 7.00, and admission to the neonatal intensive care unit (NICU). Results: Reasons for performing planned cesarean delivery before the scheduled date were as follows: onset of labor (n = 109; 50.0%), rupture of membranes (n = 85; 39.0%), preeclampsia (n = 9; 4.1%), scar pain in women with a previous cesarean (n = 6; 2.8%), unexplained vaginal bleeding (n = 5; 2.3%), and nonreassuring fetal heart rate (n = 4; 1.8%). Mean gestational age for planned cesarean deliveries before the scheduled date was 38.7 weeks ± 0.8 versus 39.2 weeks ± 0.7 for those performed when scheduled (P < 0.0001). The maternal morbidity composite outcome rate was significantly higher among planned cesareans performed early compared with those on the scheduled date: 18.3% vs 9.7%, respectively, P = 0.0002. It was still higher in the multivariable analysis: aOR 2.17, 95% CI 1.46–3.21, P = 0.0001. The neonatal composite outcome did not differ significantly between the two groups. Conclusion: In planned cesarean deliveries, maternal morbidity is higher for cesareans performed before rather than on the scheduled date. Studies without accurate intent-to-treat analyses underestimate the morbidity associated with planned cesareans. Accordingly, medical records must make it possible to distinguish planned cesarean deliveries performed before the scheduled date from those performed as planned.
