Posterior Cervical Angle and Cervical Length in Predicting the Successful Induction of Labour in Nulliparous Woman

Abstract

Induction of labor is the most common intervention in modern obstetrics. Success of the induction of labor is determined by the initial state of the cervix. Traditionally, preinduction cervical assessment is based on the digital examination of the cervix using the pelvic scoring system proposed by Bishop which is simple and easy to perform. Several studies have shown it to be subjective, with high inter- and intra-observer variation; it is found to be a poor predictor of the outcome of labor induction. Recently several authors have tried to find a more objective assessment of the cervix using transvaginal ultrasound for the prediction of outcome of labor induction. The aim of this study is to assess the effectiveness of transvaginal measurement of cervical length & posterior cervical angle prior to induction of labor in prediction of successful induction and to compare its effectiveness with bishop score. This study was conducted at the department obstetrics & gynecology, Ain Shams Maternity Hospital from the period of November 2018 to May 2019. A total of 70 women consented to participate in this study.
