The Success of Intravaginal Dinoprostone in the Induction of Labor of Term Pregnancies with Intrauterine Growth Restriction

Objective: In this study, it was aimed to evaluate the use of dinoprostone ovul in labor induction and the induction success of fetuses with growth restriction.
Methods: In this retrospective study, 134 pregnant women who were diagnosed with intrauterine fetal growth restriction (IUGR) and used vaginal dinoprostone for labor induction were included. The gestational week of all patients is >37 and Bishop score <6. The success of induction was evaluated as vaginal delivery. Demographic characteristics, maternal and neonatal outcomes of the patients were recorded.
Results: Eighty-three (61.9%) of our patients had vaginal delivery (successful induction) and 51 (38.1%) had cesarean delivery (unsuccessful induction). Bishop score (2.8±0.8 and 2.3±0.5 p=0.01, respectively) and gravidas of patients with successful induction were higher (1.81±0.78 and 1.58±0.88, respectively, p=0.03). In addition, the patients in the successful induction group had a had more labor induction history in their previous pregnancies (p=0.04). No correlation was found between induction success with the parameters of gestational week, maternal body mass index, fetal birthweight, low abgar score, presence of meconium, neonatal intensive care need.
Conclusion: Successful labor induction with dinoprostone in fetuses with IUGR is associated with increased number of pregnancies, high Bishop score and presence of induction in previous delivery.
