Summary

Perineal trauma is a common complication of vaginal delivery, particularly among primiparous patients, and may result in short- and long-term maternal morbidity, including pain, dyspareunia, and pelvic floor dysfunction. Papaverine hydrochloride, a smooth muscle relaxant with vasodilatory properties, has been shown to improve tissue relaxation and has been used safely in obstetric settings.

This prospective randomized double-blind placebo-controlled study aims to evaluate whether intrapartum intravenous papaverine hydrochloride (80 mg), administered at full cervical dilatation, reduces the rate of perineal trauma among primiparous patients undergoing vaginal delivery. Eligible participants will be randomized in a 1:1 ratio to receive either intravenous papaverine hydrochloride or placebo (normal saline). Maternal, obstetric, and neonatal outcomes, including the rate and severity of perineal trauma, obstetric anal sphincter injuries (OASIS), postpartum hemorrhage, and neonatal outcomes, will be assessed.

Conditions

  • Perineal Trauma
  • Obstetric Anal Sphincter Injury

Interventions

DRUG

Papaverine Hydrochloride

Intravenous papaverine hydrochloride 80 mg diluted in 100 mL normal saline administered at full cervical dilatation during labor. The study medication will be administered following complete cervical dilatation and prior to delivery in primiparous patients undergoing vaginal birth.

DRUG

Placebo

Placebo consisting of 100 mL normal saline administered intravenously at full cervical dilatation during labor. The placebo solution will be prepared in an identical manner to maintain blinding.
