Summary
Labor induction occurs in 19.7% of pregnancies, with failed induction leading to operative delivery in 74.07% of cases. Factors like nulliparity, advanced maternal age, obesity, and low Bishop score increase failure rates.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
Background:
- Labor induction is a common obstetric intervention.
- Understanding its incidence, indications, and predictors of failure is crucial for optimizing maternal and fetal outcomes.
Purpose of the Study:
- To determine the incidence and indications for labor induction.
- To identify predictors of failed labor induction.
Main Methods:
- A prospective hospital-based study was conducted over 12 months.
- Singleton pregnancies beyond 37 weeks with vertex presentation and an unscarred uterus were included.
Main Results:
- The incidence of labor induction was 19.7%. Post-term pregnancy was the primary indication (51.28%).
- Failed induction was associated with nulliparity (41.2%), maternal age >30 years (53.8%), obesity (44.4%), and a Bishop score <5 (40.8%).
- Higher rates of operative delivery were observed in the induction group (34.6%) compared to spontaneous labor (27.4%).
Conclusions:
- Labor induction increases the rate of operative delivery.
- Careful patient selection and adherence to practice guidelines are necessary to mitigate risks associated with induction and reduce high operative delivery rates.
