title: Outcome of induced labor in 931 term pregnancies.
abstract: An analysis of 931 consecutive inductions of labor over an eight-year period is presented. The success rate was 90.4%. Spontaneous vaginal delivery was achieved in 83.5% of cases and the induction-delivery interval was less than 12 hours in 82.6% of cases. The preinduction state of the cervix most significantly influenced the outcome of labor, followed by maternal age and parity. Provided induction of labor was by synchronous use of forewater amniotomy and oxytocin titration, labor outcome was regularly predictable two hours after induction using the concept of latent period of labor and the cervical dilatation at eight hours from the induction. When the latent period was two hours or less, 64.2% of the patients delivered within eight hours, and vaginal delivery was achieved in all women in whom the cervical dilatation was 8 cm or more at eight hours from the induction of labor. The maternal complication rate was 12.1%, the early neonatal morbidity was 11.6%, and the stillbirth rate was 2.3%.
