Objective:
To compare vaginal delivery rate and perinatal outcomes of fetuses with late-onset fetal growth restriction (FGR) undergoing labor induction, depending on the method for cervical ripening (dinoprostone vs. Foley balloon).
Material And Methods:
We conducted a retrospective cohort study of 148 consecutive singleton gestations diagnosed with stage I late-onset FGR and Bishop score < 7, in which labor induction was indicated at ≥37 + 0 weeks. Before January 2016, cervical ripening was achieved with 10 mg of vaginal dinoprostone (n = 77) and afterwards with Fo-ley balloon (n = 71). Logistic regression analysis was used to estimate the association between mode of delivery and induction method.
Results:
Foley balloon had lower percentages of uterine tachysystole with fetal repercussion (4.2 vs. 16.9%, p = 0.01) and cesarean sections for suspected fetal distress (7.0 vs. 26.0%, p < 0.01) when compared to dino-prostone. Lower percentages of cesarean sections were found in the Foley balloon group (15.5 vs. 37.7%, p < 0.01). The odds ratio and adjusted odds ratio of cesarean section with dinoprostone were of 3.3 and 4.4, respectively. Perinatal mortality and severe morbidity were null in both groups.
Conclusion:
The use of Foley balloon resulted in a higher percentage of vaginal delivery compared to dinoprostone, with a favorable safety profile in both groups.
