摘要
目的 探讨前置胎盘患者发生产后出血的相关因素 ,寻求在产前评估产后出血的预测方法。 方法 回顾性分析 1996年 1月～ 2 0 0 0年 12月 5年间 ,在我院住院分娩的 136例前置胎盘病例产前各相关因素及妊娠结局。 结果 ( 1)前置胎盘的发生率为 1.2 4 % ,其产后出血发生率为2 2 .0 6 % ;( 2 )与前置胎盘产后出血量有关的因素有高龄产妇、2次以上流产史、剖宫产史、前壁的前置胎盘、完全性前置胎盘、有产前出血史、无产前检查、存在妊娠合并症或并发症 ;( 3)以产前存在的与产后出血量有关的因素作为产后出血危险因素评分 ,若评分≥ 4分则可能发生严重产后出血。 结论 ( 1)前置胎盘产后出血量与有高龄产妇、2次以上流产史、前次剖宫产史、前置胎盘的分类、有产前出血史、无产前检查、存在妊娠合并症或并发症显著相关 ;( 2 )鉴于产前同时存在危险因素 4项以上极易发生产后出血 。
Objective To investigate the risk factors of postpartum haemorrhage(PPH) in placenta previa. Methods A retrospective analysis of 136 cases with placenta previa from Jun.1996 to Dec. 2000 was performed. Results The incidence of placenta previa was 1.24%(136/10967) and the rate of postpartum haemorrhage was 22.06%(30/136). The associated factors of postpartum haemorrhage in placenta previa were history of multiple abortions (more than twice) , previous cesa rean section, elder age, type of placenta previa, no prenatal check, prenatal bleeding and other complications. PPH might happen when the high risk factor score was more than 4. Conclusions The relative factors of postpartum haemorrhage in placenta previa are abortions more than twice, previous cesarean section, older age, types of placenta previa, absence of prenatal check, antepartum hemorrhage and other complications. We can predict PPH by high risk factor score.
