Abstract
Objective: To examine predictive characteristics for cesarean delivery (CD) in women undergoing labor induction with a Foley balloon (FB). Methods: A secondary analysis of a randomized, double-blind, control trial examining labor induction with a transcervical 30mL or 60mL FB. One-hundred ninety-nine women with term, vertex, singleton pregnancies and Bishop score <5 were randomized to receive a transcervical 30mL or 60mL FB. Mode of delivery, labor complications and neonatal outcomes were recorded. A multivariable model was performed to determine predictive characteristics for CD. Results: Increasing maternal age (p=0.04), nulliparity (p=0.002) and chorioamnionitis (p<0.001) were significantly associated with an elevated risk for CD. Nulliparity was associated in an almost 4-fold increased CD risk (relative risk [RR]: 3.88; 95% confidence interval [CI]: 1.22-12.3). Women aged 40 years, had an almost 3-fold increased risk of CD as compared to women aged 20-29 (RR: 2.91; 95% CI: 1.36-6.19) years. Chorioamnionitis was associated with nearly a 2-fold increased risk for CD (RR: 1.87; 95% CI: 1.06-3.32). A gestational age of 41 weeks, prostaglandin use during induction and induction indication did not affect mode of delivery. Conclusion: In patients undergoing labor induction with a FB, increasing maternal age, nulliparity and chorioamnionitis are associated with an elevated risk for CD.
