What this Trial Is About

This research aims to compare how the left lateral decubitus position versus the supine position affects the length of the active phase of labor in first-time mothers. The trial focuses on nulliparous women at term with a single baby in head-down position who are in active labor. It seeks to provide local evidence on whether maternal position can influence labor duration and potentially reduce cesarean sections and complications. Participants will be randomly assigned to either lie in the left lateral decubitus position or remain in the supine position. Each position will be maintained in cycles of 30 minutes with 5-minute rest intervals during the active labor phase until delivery. Two groups are compared: the experimental group in the left lateral position and the control group in the supine position. During the study, maternity and newborn outcomes such as the active labor duration, cesarean rates, use of labor medications, maternal complications, and newborn Apgar scores will be recorded. Follow-up includes monitoring until hospital discharge and assessments shortly after birth. Participants are followed from active labor onset until delivery and postpartum recovery, with data collected on labor progression and maternal and neonatal health.
