Objective : To assess the rates of cesarean deliveries and perinatal outcome following intrapartum transcervical amnioinfusion in women with meconium‐stained amniotic fluid (MSAF) in a setting with no electronic fetal monitoring or specialized neonatal care. Materials and methods : In this prospective comparative study with 150 women who were in labor and had MSAF, 50 of the women received a transcervical amnioinfusion and the remaining 100 women received standard care. The inclusion criteria were a pregnancy of at least 37 weeks' duration, a single live fetus in cephalic presentation, no major medical or obstetric complications, and no known fetal malformation. The amnioinfusion was performed with 1000 mL of normal saline solution through a red rubber catheter. Results : Amnioinfusion was associated with a significant decrease in the incidence of low Apgar score (< 7) at 1 min (12% vs. 47%; relative risk [RR], 0.26; 95% confidence interval [CI], 0.12–0.56); low Apgar score at 5 min (4% vs. 23%; RR, 0.17; 95% CI, 0.04–0.71); and meconium aspiration syndrome (4% vs. 18%; RR, 0.22; 95% CI, 0.05–0.92). There was also a trend towards a lesser incidence of cesarean deliveries (18% vs. 30%; RR, 0.6; 95% CI, 0.31–1.16) and perinatal deaths (4% vs. 13%; RR, 0.31; 95% CI, 0.07–1.31). The incidence of maternal hospital stays longer than 3 days was significantly lower in the amnioinfusion than in the control group (24% vs. 48%; RR, 0.5; 95% CI, 0.29–0.85). There were no major complications related to amnioinfusion. Conclusions : Intrapartum amnioinfusion for MSAF is a simple, safe, effective, and inexpensive procedure feasible in settings where intrapartum monitoring is limited. It is associated with improved perinatal outcome and could lower cesarean delivery rates in low‐resource countries.
