妊娠晚期前置胎盘67例临床分析

Clinical analysis on outcome of pregnancy in late pregnancy women with placenta previa

目的探讨妊娠晚期前置胎盘发生的高危因素、诊断及有效分娩方式。方法回顾性分析我院2007-08～2011-08产科收治的67例妊娠晚期前置胎盘患者的临床资料。结果第一次妊娠者发生前置胎盘的比例较高;前置胎盘患者发生早产、产后出血、宫腔填纱的概率较高;前置胎盘误诊率及漏诊率较高。结论对年轻孕妇病史采集需认真详细;终止妊娠前尽量明确胎盘位置,提高产前诊断率;低置性前置胎盘患者应尽量行阴道试产以降低剖宫产率及产后出血率。

Misdiagno- sis and missed diagnosis rate of placenta previa was higher. Conclusion For young pregnant women the collection of medical history should be carefully performed; Before termination of pregnancy the location of placenta sho^dd be clearly defined to improve the prenatal diagnosis rate;For women with low laying placenta, the trial vaginal delivery should be performed as much as possible to reduce the rate of cesarean section and postpartum hemorrhage.
