Summary
Outpatient prostaglandin (PG) E2 gel significantly shortened the time to delivery and labor duration in pregnant women. This method offers a faster route to childbirth for eligible individuals.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Medicine
- Clinical Trials
Background:
- Induction of labor is a common obstetric procedure.
- Cervical ripening is a critical step for successful labor induction.
- Prostaglandin E2 (PGE2) is a known agent for cervical ripening.
Purpose of the Study:
- To evaluate the efficacy of outpatient intracervical prostaglandin E2 gel in reducing the interval to delivery.
- To assess the impact of PGE2 gel on labor duration.
Main Methods:
- A randomized, double-blind, placebo-controlled trial was conducted.
- 61 pregnant women at >= 38 weeks gestation with Bishop scores < 9 received either 0.5 mg PGE2 gel or placebo intracervically.
- Cervical length, fetal fibronectin, and Bishop score were assessed prior to gel administration.
Main Results:
- The PGE2 group had a significantly shorter median interval to delivery (2.5 days) compared to placebo (7 days).
- Fifteen women in the PGE2 group delivered within 2 days versus five in the placebo group (P = .007).
- Active labor phases were shorter in the PGE2 group, particularly for those with a negative fetal fibronectin test.
Conclusions:
- Outpatient administration of intracervical PGE2 gel effectively shortens the interval to delivery.
- PGE2 gel also leads to a reduction in labor duration.
