Our study had analyzed obstetric results of patients who had unripe cervix before IOL and used preinduction with obstetric results of patients in whom, due to favorable cervix, only a low-dose infusion of oxytocin was used.
We reviewed the medical records of 1010 single pregnancies in whom IOL was performed. We divided the patients into groups A and group B, where preinduction was not used. Patients in group A were more likely to complete the delivery by cesarean section and more likely to have events that were indications for operative delivery: nonreassuring fetal heart rate trace and arrested labor or failed induction.
The groups did not differ in the percentage of vacuum extraction, postpartum hemorrhage, and meconium-stained amniotic fluid. In group B, more infants were born with umbilical cord blood pH <7.1, and both groups included no deliveries of newborns with an Apgar score ≤of 3 points.
The groups did not differ in terms of the percentage of newborns Apgar score between 4 and 7 at birth. The immature cervix and the need to use labor preinduction is a risk factor for cesarean section. The necessity of preinduction does not impair neonatological results.
