Objective: The purpose of this study was to assess clinical characteristics of induction of labor group in nulliparous women at term with a single fetus in cephalic presentation.
Methods: we reviewed retrospectively the edical records of 73 nulliparous women delivered between August 2004 and July 2006. The patients were classified as induction of labor group and spontaneous onset of labor group to compare of obstetrical data. Student t-test, Chi-square, and Fisher’s exact test were performed.
Results: Induction of labor group than spontaneous onset of labor group had higher < or =4 of Bishop score cervical status and time from admission to delivery was longer (p<0.05). The rate of cesarean delivery and meconium stained amniotic fluid were higher in induction of labor group (p<0.05). In case of Bishop score is higher than 4, normal vaginal delivery is higher than cesarean delivery (p=0.100).
Conclusion:Induction of labor in nulliparous women is associated with low Bishop score and an increased risk of cesarean delivery. Success of vaginal delivery is tightly associated with favorable cervical status.
