Bishop's score > 8 traditionally thought to predict good chance of vaginal delivery with induction of labor
n.b. Bishop's Score correlates poorly with outcome of induction of labor. In a study of 443 women with Bishop's score < 9 who required delivery and given either hygroscopic cervical dilation or PGE2 for cervical ripening, cervical dilation alone both before and after cervical ripening was a better predictor than the Bishop's score of successful labor induction, duration of latent phase, duration of second stage, oxytocin use, and successful vaginal delivery (Obs.
