The Comparison of Maternal Endometritis in Meconium – Stained Amniotic Fluid and Clear Amniotic Fluid

Introduction: Metritis is one of the causes of maternal morbidity and there are many risk factors for it. Because of the importance of possible association of meconium-stained amniotic fluid and maternal metritis the present study was done to determine whether meconium stained amniotic fluid (MSAF) is associated with puerperal infection. Methods: In this case-control study 150 women with MSAF and 150 women with clear amniotic fluid (gestational age > 37 weeks) were compared for puerperal metritis. Results: Subjects’ educational level, gestational age, gravida, mean vaginal exams, route of delivery and mean neonatal weight were not significantly different between the two groups. But mean maternal age and neonatal Apgar were significantly different in the two groups. That is, post partum metritis in women with clear amniotic fluid occured less than women with MSAF (2.7% vs 10%, P<0.014). Conclusion: Since meconium stained amniotic fluid is associated with metritis, special care in this regard is recommended.
