Is this trial a fit for you?

Likely a good fit

Eligible candidates are adults 18+, at 37 weeks or more gestation with PROM 2–12 hours, no active contractions, and cervix dilated less than 2 cm with vertex presentation.

Probably not a fit

Patients with active labor (cervical dilation ≥6 cm), prior cesarean, uterine contraindications, or other exclusion criteria may not benefit and could be at higher risk.

What this trial studies

This randomized, double-blind, placebo-controlled study enrolls pregnant individuals at 37 weeks or later with term PROM and no active labor. Participants receive either intravenous papaverine 80 mg in saline or saline placebo, one hour after starting oxytocin, with treatment allocation kept blinded. The main goal is to measure the time from study infusion to delivery, while secondary outcomes include mode of delivery and maternal and neonatal outcomes. Eligible women are 18 or older, with minimal cervical dilation and specific exclusion criteria to ensure safety. The study is led by Wolfson Medical Center and conducted at The Edith Wolfson Medical Center in Holon, Israel.

Why it matters

Potential benefit: If successful, the approach could shorten labor duration after PROM and potentially improve delivery outcomes.

How similar studies have gone: Prior similar approaches are limited in this exact context; this trial explores a novel adjunctive use of papaverine with oxytocin in term PROM.
