Intravenous Papaverine for Term Prelabor Rupture of Membranes
The Effect of Papaverine on Labour in Term Premature Rupture of Membranes (PROM)
調査の概要
詳細な説明
Women hospitalized in the labor and delivery unit with term premature rupture of membranes at 37 weeks of gestation or later are screened for participation. Eligible participants have no active contractions, cervical dilation of less than 2 cm, vertex presentation, and a duration of membrane rupture between 2 and 12 hours.
Following informed consent, participants are randomized in a 1:1 ratio to receive intravenous papaverine 80 mg diluted in 100 mL of 0.9% saline or 100 mL of 0.9% saline as placebo. The study infusion is administered one hour after initiation of oxytocin.
Treatment allocation is blinded. One study-team member prepares the study solution according to the randomization table, while the remainder of the study team remains blinded to treatment allocation. The primary outcome is the interval from study infusion to delivery.
