Induction of Labor Affected Fetus / Newborn

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

Interventions

PROCEDUREManipal ultrasound scoring system

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.

PROCEDURELevine scoring system

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