羊水粪染与产后出血的关系探讨

目的:探讨单胎自然分娩中羊水粪染与产后出血的关系.方法:选择孕足月、单胎、头位、无严重内外科合并症,羊水粪染、胎儿情况正常的初产妇60例为研究组;选择同期条件相同、羊水清亮的100例初产妇为对照组,比较两组总产程时间、新生儿体重、产后24 h出血量及分娩前后24 h血红蛋白浓度的差值.结果:两组总产程时间、新生儿体重比较,差异无统计学意义;研究组的产后24 h出血量是344.50±91.70 mL,明显多于对照组的287.15±58.76 mL.P<0.05;研究组分娩前后血红蛋白浓度的差值是6.44±8.49 g/L,明显大于对照组的2.96±3.81 g/L,P<0.05.结论:羊水粪染的产妇产后出血量多,产后出血发生率高.

Study of the Relationship Between Meconium Stained Amniotic Fluid and Postpartum Hemorrhage

Objective：To investigate the relationship between meconium stained amniotic fluid and postpartum hemorrhage in singleton natural term labor. Methods： 60 women of term monocyesis, with meconium stained amniotic fluid, head presentation,Without serious medical or surgical complications （study group） and 100 women with clear amniotic fluid （control group） were enrolled into this study, all of their fetuses were in good status. The total time of labor, body weight of newborn, volume of postpartum hemorrhage in 24 h, hemoglobin antepartum and postpartum were recorded and compared. Results： There were no significant differences in the total time of labor and the body weight of newborn between two groups （P〉0.05）. The volume of postpartum hemorrhage in 24 h in study group was significantly more than that the in control group （344.50±91.70 mL vs 287.15±58.76 mL,P〈O.05）,the hemoglobin difference antepartum and postpartum in study group was significantly greater than that in control group （6.44±8.49 g/L vs 2.96±3.81 g/L,P〈O.05）. Conclusions： Women with meconium stained amniotic fluid would bleeding more,the rate of postpartum hemorrhage is high.
