Papaverine to shorten the second stage of labor after double-balloon cervical ripening
Official title: Use of Papaverine to Shorten the Second Stage/Duration of Labor in Pregnant Women After Cervical Ripening by Double-balloon Catheter
Run by Hillel Yaffe Medical Center · NCT07237880 · Data updated 2026-11-12
We will test whether a single IV dose of papaverine given right after removing a double-balloon catheter can shorten labor for term pregnant women having labor induced.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are pregnant people aged 18–50 with a singleton fetus at 37–42 weeks admitted for induction with a double-balloon catheter who plan a vaginal delivery and can give informed consent.
✕Probably not a fit
Patients with prior cesarean delivery, contraindications to vaginal delivery, immediate need for delivery, multiple gestation, major fetal anomaly, or known papaverine allergy are unlikely to benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, randomized, double-blind, placebo-controlled trial enrolling term (37–42 weeks) singleton pregnancies admitted for induction with a double-balloon catheter. After catheter removal participants are randomized 1:1 to receive either 80 mg IV papaverine or an identical-appearing saline placebo given by a midwife who does not make clinical decisions. Clinical staff and participants remain blinded to allocation, and outcomes focus on labor duration and progression after mechanical cervical ripening. The protocol excludes prior cesarean delivery, multiple gestation, contraindications to vaginal birth, known major fetal anomaly, or hypersensitivity to papaverine.
Why it matters
Potential benefit: If successful, this could shorten the duration of labor after mechanical cervical ripening and potentially reduce the need for additional interventions.
How similar studies have gone: Papaverine is used as an obstetric antispasmodic in practice, but its specific effect on labor progression after mechanical cervical ripening has been largely untested in randomized trials.

PGE2 then oxytocin versus oxytocin for starting labor after your water breaks at term.
This test will see whether giving a 6-hour vaginal dinoprostone (PGE2) insert before oxytocin or starting oxytocin right away works better for women 18 and older with a single baby whose water breaks at 37–42 weeks and whose cervix isn't ready.
-
Topical numbing cream for balloon-catheter cervical ripening
This trial will test whether applying a numbing cream (lidocaine‑prilocaine, EMLA) to the perineum and posterior vaginal wall before balloon catheter insertion reduces pain for people 34+ weeks pregnant who need labor induction.

How information about planned labor induction affects childbirth experience
This project will see if being well informed about a planned induction of labor and patterns of social media use change the childbirth experience for people having a scheduled induction.

Evaluating membrane stripping for cervical ripening in labor induction
This study tests whether a method called membrane stripping works better than a double balloon catheter for helping women get ready for labor.

Lactated Ringer's with 5% dextrose versus Lactated Ringer's alone during induced labor
This test gives women having an induced, first-time labor either Lactated Ringer's with 5% dextrose or Lactated Ringer's alone to see which shortens labor and whether the extra sugar affects newborn blood sugar.
