摘　　要：目的探讨前置胎盘发生的相关危险因素及其对妊娠结局的影响。方法回顾性分析本院2005年1月～2012年5月住院分娩的4892例产妇资料,分析导致前置胎盘发生的因素及妊娠结局。结果前置胎盘病例63例,发病率为1.29%,年龄>35岁、经产妇、流产次数>2次、有吸烟史、盆腔炎史及子宫手术史是导致前置胎盘发生的高危因素(P<0.05)。妊娠结局:阴道分娩4例(6.35%),剖宫产59例(93.65%),发生新生儿窒息8例(12.70%),分娩孕周<36周者18例(28.57%),≥36周者45例(71.43%);剖宫产率、分娩孕周及出血量在边缘性、部分性及完全性前置胎盘患者中比较差异均具有统计学意义(P<0.05),新生儿窒息发生率差异无统计学意义(P>0.05)。结论高龄、经产妇及多数流产、有吸烟史、盆腔炎史及子宫手术史是导致前置胎盘发生的主要高危因素,前置胎盘时剖宫产率、早产率及产后出血量明显增高。Objective To explore the influnce of risk factors associated with placenta praevia and its effect on pregnancy outcome.Methods Four thousand eight hundred and ninety-two cases of maternal data from January 2005 to May 2012 in our hospital year were retrospectively analyzed,and the outcome led to the placenta praevia factors and pregnancy were analyzed.Results Among 63 cases of patients with placenta previa,the incidence rate was 1.29%,age was above 35 years,the number of abortion,maternal was above 2,smoking history,pelvic inflammatory disease of uterus and operation history were the results of high risk factors of placenta praevia（P 〈0.05）.Outcome of pregnancy：4 cases were vaginal delivery（6.35%）,59 cases were cesarean section（93.65%）,the incidence of neonatal asphyxia were 8 cases（12.70%）,gestational weeks above 36 weeks were 18 cases（28.57%）,over 36 weeks were 45 cases（71.43%）;the comparison of rate of cesarean section,gestational weeks and the amount of bleeding in borderline,partial and complete placenta previa patients had sig nificant difference（P 〈0.05）,the rate of neonatal asphyxia showed no statistical difference（P 〈0.05）.Conclusion Age,maternal and plurality of abortion,smoking history,pelvic inflammatory disease of uterus and placenta previa operation his tory are the results of the main risk factors of placenta previa.The rate of cesarean section,preterm birth and postpartum hemorrhage volume increases significantly when placenta previa.
