Abstract
Cervical ripening can be promoted in many ways, but mechanical methods are among the oldest. Like all other methods, this one also has its pros and cons. Disadvantages compared to pharmacological methods include some maternal discomfort upon manipulation of the cervix, a theoretical increase in the risk of maternal and neonatal infection from the introduction of a foreign body, potential disruption of a low-lying placenta, and increase in the need of oxytocin induction of labor. The aim of the study was to evaluate the effect of using cervical ripening balloon in preinduction on the mode of delivery. This was a longitudinal, cohort, intervention, non-randomized one center study. Inclusion criteria were term pregnancies with gestational diabetes, oligohydramnios, intrauterine growth restriction, gestational hypertension/preeclampsia and pregnancies after 41 weeks of pregnancy. Preinduction of labor was performed in term pregnancies at Sestre milosrdnice University Hospital Center. Results in the first 150 women having undergone labor preinduction with cervical ripening balloon were included. Two-sided p values <0.05 were considered significant. Statistical analysis was done using SPSS Version 20.0. The study included 150 women; one woman was excluded from further analyses due to conversion of fetal presentation (head to breech). Indications for labor preinduction were as follows: gestational diabetes, oligohydramnios, intrauterine growth restriction, gestational hypertension/preeclampsia and pregnancies after 41 weeks of pregnancy. Women with normal vaginal delivery (96/149) had lower rates of gestational diabetes and oligohydramnios and used epidural analgesia more frequently. Women with dystocia (32/53) had a significantly longer labor duration and higher neonatal birth weight. In multivariate analysis, multiparity, greater cervical dilatation after balloon removal and use of epidural analgesia were associated with a decreased risk of cesarean section, while the presence of gestational diabetes and oligohydramnios was associated with an increased risk of cesarean section. We found this preinduction method safe and efficient, with a potential to increase the rate of vaginal deliveries.
