Brief Summary

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

Conditions

Induction of Labor Affected Fetus / Newborn

Outcome Measures

Primary Outcomes (1)

• The rate of successful induction of labor

  an ability to achieve the active phase of labor corresponding to a cervical dilatation of ≥4 cm within 12 h of initiating oxytocin on the first day of induction

  24 hours

Study Arms (1)

study group

All pregnant women who will attend the labor unit for induction of labour due to different indications during the study period will be invited to participate in the study.

Procedure: Manipal ultrasound scoring system; Procedure: Levine scoring system

Interventions

Manipal ultrasound scoring system PROCEDURE

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.

study group

Levine scoring system PROCEDURE

maternal height, parity, body-mass index (BMI) at delivery and the results of modified Bishop's score in calculation of probability of CS

study group
