Objective: This study aimed at determining the mode of delivery, maternal, and perinatal outcomes of induction of labor (IOL) in postdated pregnancies.
Methods: It was a prospective observational study. Nulliparous women with uncomplicated singleton pregnancies who have crossed their estimated date of delivery (EDD) were included in the study. Inclusion and exclusion criteria were strictly followed. A total of 280 patients were divided into study and control groups. Those who underwent IOL immediately after EDD were compared with women who were managed expectantly up to 42 weeks.
Results: The study group and control group consisted of 150 and 130 women, respectively. The rate of cesarean section (CS) (64.62%) was significantly higher in an expectantly managed group. The most common indication of the CS was fetal distress in both groups, and the occurrence of oligohydramnios was quite higher in the control group. The rate of shoulder dystocia, cervical tear, and third- and fourth-degree perineal tear was significantly more in an expectantly managed group. Fetal distress was also more in that group.
Conclusion: Our study suggests that labor should be induced after crossing EDD if gestational age is confirmed so that the incidence of maternal and perinatal complications can be brought down to an acceptable level.
