摘要
目的研究导致前置胎盘孕妇产后出血的高危因素。方法选取2013年1月至2016年7月在本院确诊的120例前置胎盘并行剖宫产孕妇为研究对象。根据剖宫产娩出胎儿后24 h内的出血量,分为产后出血组(出血量≥1 000 ml)46例,非产后出血组(出血量<1 000 ml)74例。对其临床表现和产检结果进行分析比较,探究导致前置胎盘孕妇产后出血的高危因素。结果产后出血组患者合并瘢痕子宫、凶险性前置胎盘、胎盘植入和中央性前置胎盘的发生率,均明显多于非产后出血组患者,组间差异有统计学意义(P<0.05);两组患者部分性前置胎盘和边缘性前置胎盘比较,差异无统计学意义(P>0.05)。结论发生瘢痕子宫、中央性前置胎盘、凶险性前置胎盘和胎盘植入的产妇产后出血率更高,可视为导致前置胎盘孕妇产后出血的高危因素。
Objective To evaluate the high risk factors of postpartum hemorrhage in placenta previa.Methods Selected 120 pregnant women who were diagnosed as placenta previa and undergone cesarean section in our hospital during Jan 2013 and July 2016. According to the amount of bleeding within 24 h of cesarean section fetus,they were divided into postpartum hemorrhage（ 46 cases,bleeding 1000 ml） and non postpartum hemorrhage group（ 74 cases,bleeding1000 ml）. Then found the risk factors by analyzing and comparing their prenatal clinical manifestations and antenatal results.Results In the postpartum hemorrhage group,the incidence of scar uterus,dangerous placenta previa,placenta accrete and Placenta previa centralis was significantly higher than those in the non postpartum hemorrhage group（ P〈0. 05）. The occurrence of partial placenta previa and marginal placenta previa between the two groups was not statistically significant（ P〉0. 05）. Conclusions This study shows that patients with scar uterus,central placenta previa,dangerous placenta previa and placenta accrete have higher probability of postpartum hemorrhage,those can be regarded as high risk factors of postpartum hemorrhage in placenta previa.
