Analgesic Efficacy and Obstetric Effects of Tramadol, Paracetamol and Placebo in Active Labor (NCT07440069)

Analgesic Efficacy and Obstetric Effects of Tramadol, Paracetamol and Placebo in Active Labor: A Randomized Double-Blind Controlled Trial

🟢 Recruiting Phase4 💊 Investigational Drug / Biologic Sponsor: Universidad Nacional Autonoma de Honduras

🩺 Plain-English Summary (8th-Grade Level)

This randomized, double-blind, placebo-controlled trial aims to compare the analgesic efficacy and obstetric effects of tramadol (100 mg IV) versus paracetamol (1 g IV) versus placebo (saline solution) in nulliparous women during active labor. The primary outcome is duration of active labor (minutes). Secondary outcomes include duration of expulsive phase, type of delivery, need for oxytocin augmentation, maternal adverse events (nausea, vomiting, somnolence, hypotension), and neonatal outcomes (Apgar scores at 1 and 5 minutes, NICU admission). The study hypothesizes that tramadol significantly reduces active labor duration compared to paracetamol and placebo, without compromising maternal or neonatal safety. A total of 300 nulliparous women (100 per group) will be enrolled at Hospital Escuela, Tegucigalpa, Honduras.
