剖宫产术后再次妊娠并发前置胎盘的临床分析

The Clinical Study of Pregnancy Complicated With Placenta Previa Again After Cesarean Section

目的：观察和评价剖宫产术后再次妊娠并发前置胎盘的临床分析，为孕产妇围产儿死亡率提供参考和借鉴意义。方法选取2011年6月～2014年12月我院收治的因剖宫产术再次妊娠并发前置胎盘孕产妇38例作为观察组，随机选取同期无剖宫产术史前置胎盘患者38例作为对照组，通过对比对照组与观察组孕产妇和围产儿的临床表现。结果通过临床观察和对比分析，观察组剖宫产率高于对照组，差异具有统计学意义（P＜0.05）；观察组孕产妇胎盘植入发生率、产后出血量和子宫破裂发生率均高于对照组（P＜0.05）；在围产儿早产率、胎儿窘迫率方面，观察组高于对照组（P＜0.05）。结论剖宫产术后再次妊娠并发前置胎盘会引起孕产妇和围产儿的并发症与风险的增加，要指导剖宫产术后再次妊娠的合理间隔时间，从而有效避免凶险性前置胎盘的发生。

Objective To observe and evaluate the clinical analysis of pregnancy complicated with placenta previa again after cesarean section, and provide a reference for maternal perinatal mortality and reference significance. Methods 38 cases were complicated with placenta previa maternal pregnancy as observation group from June 2011 to December 2014 in our hospital, during the same period were randomly selected patients with cesarean section prehistoric buy placenta 38 cases as control group, by comparing the control group and observation group of maternal and perinatal clinical manifestations. Results Through clinical observation and comparative analysis, the cesarean section rate of observation group was obviously higher than that of control group, the difference statistically signiifcant （P〈0.05）. Observation group of maternal placenta implantation rate, postpartum blood loss and incidence of uterine rupture were signiifcantly higher than that of control group （P〈0.05）. In perinatal premature birth rate, the rate of fetal distress, observation group is higher than the control group （P〈0.05）. Conclusion The pregnancy complicated with placenta previa again after cesarean section may cause increased maternal and perinatal complications and risk, to guide the rational time interval of pregnancy again after cesarean section, thus effectively avoid dangerous sex of placenta previa.
