Accuracy of Different Scoring Systems for Predicting Successful Induction of Labor

Assiut University400 enrolled

Overview

Induction of labour (IOL) nowadays is a common procedure in obstetric practice. Presently, IOL is done for 20% of pregnancies for various maternal and fetal indications and nearly 20% of labour inductions end up in caesarean deliveries. The success of IOL mainly depends upon "favourability" of the cervix which is usually assessed by manual examination and Scored as Bishop Score. However, this method is limited by subjectivity and reproducibility and though done in all the patients prior to IOL, several studies have demonstrated poor correlation between Bishop Score and outcome of IOL

Induction of Labor Affected Fetus / Newborn

Interventions

Manipal ultrasound scoring systemPROCEDURE

length of the cervix from the internal to external os, presence or absence of funneling and if present width and length of funneling at internal os were measured. Distance between presenting part to external os will be measured and position of the cervix i.e. whether curved or straight will also noted.
