ABSTRACT
The aim of this study was to determine whether preinduction cervical ripening with
prostaglandin E2 (PgE2) gel in patients with one previous cesarean section may be used with the same safety
and efficacy as in patients without a uterine scar. Primiparous patients (n = 94) with one previous cesarean section were retrospectively compared to nulliparous
patients (n = 866). Both groups underwent preinduction cervical ripening with 2 mg intracervical
PgE2 gel. Logistic regression was performed to control for confounding factors. Our statistical
power was 90% for detecting a doubling of the complication rate, from 10 to 20%. There
were no significant differences in the duration of ruptured membranes or length of
labor between the two groups. No significant differences were detected in the rate
or indications for cesarean section, presence of thick meconium, epidural anesthesia
use, amnionitis, or maternal and neonatal morbidity. There were no cases of uterine
rupture in either group. PgE2 gel may be used with the same safety and efficacy in patients with previous cesarean
section as in nulliparas.
