前置胎盘产前出血的相关危险因素及对妊娠结局的影响

The Related Risk Factors of Antepartum Hemorrhage for Patients with Placenta Previa and the Effect on Pregnant Outcome

目的:探讨前置胎盘患者产前出血的相关危险因素及对妊娠结局的影响。方法:以分娩前是否有过无痛性阴道流血将我院收治的75例前置胎盘分为出血组和未出血组,对两组资料进行回顾性分析。结果:出血组和未出血组年龄相当(P>0.05),但是孕产次数、流产以及宫腔操作次数差异显著(P<0.05或0.01)。出血组中央型前置胎盘所占比例明显较高(P<0.05)。出血组剖宫产率、早产率、产后出血率明显较未出血组高,终止妊娠时的孕周较短,住院总天数较长,和未出血组比较差异具有显著性(P<0.05或0.01)。结论:前置胎盘患者孕产次、流产以及宫腔操作次数与产前出血有一定的关系,而产前出血对前置胎盘患者的妊娠结局影响不良。

Objective ：To explore the related risk factors of antepartum hemorrhage for patients with placenta previa and the effect on pregnancy outcome .Methods ：According to whether it had painless vaginal bleeding before delivery ,75 cases of placenta previa were divided to the hemorrhage group and non hemorrhage group ,then ,the data of two groups were retrospectively analyzed .Results：The age of two groups was same （P〉0 .05） ,but the number of pregnancy ,a-bortion and uterine cavity operation was significantly different （P〈0 .05 or 0 .01） .The proportion of central type of placenta previa in hemorrhage group was higher （P〈0 .05） .The hemorrhage cesarean section rate ,premature delivery rate ,and the rate of postpartum hemorrhage was significantly higher ,termination gestational age of pregnancy was shorter ,total length of hospital stay was longer ,and compared with the non hemorrhage group ,the differences were significant （P〈0 .05 or 0 .01） .Conclusion：Antepartum hemorrhage of patients with placenta previa had a certain rela-tionship with abortion and uterine cavity operation times ,and it exhibited bad effect for the outcome of pregnancy .
