目的 分析不同类型的前置胎盘孕妇围手术期情况。方法 选取90例经我院2012年3月-2015年6月确诊为前置胎盘 孕妇的临床资料进行回顾分析，按照前置胎盘类型分为完全性前置胎盘组、部分性前置胎盘组、边缘性前置胎盘 组，每组均30例，比较孕妇在围手术期的出血、输血等出血情况，胎盘植入、胎盘粘连、产褥感染等并发症发生 率及分娩孕周。结果 完全性前置胎盘围手术期出血量、输血量明显高于其他两组（P<0.05），边缘性前置胎盘产 前出血量明显最少（P<0.05），产后出血量介于两组之间，与部分性前置胎盘差异显著（P<0.05）；完全性前置 胎盘并发症总发生率为83.3％，明显高于部分性前置胎盘（30.0％）、边缘性前置胎盘（20.0％），差异显著； 完全性前置胎盘孕妇提前分娩（<36周）发生率为73.3％，明显高于部分性前置胎盘（33.3％）、边缘性前置胎盘 （10.0％），差异显著（P<0.05），均具有统计学意义（P<0.05）。结论 不同类型的前置胎盘对母体均造成损 害，其中完全性前置胎盘临床症状明显差于部分性前置胎盘、边缘性前置胎盘，且孕周显著短于其他两组。

Objective To analyze the perioperative condition of pregnant women of different types of placenta previa. Methods 90 cases of placenta previa pregnant women admitted and treated in our hospital during March 2012 and June 2015 were selected as the study objectives. All the targeted pregnant women’s clinical data were retrospectively analyzed. According to different types of placenta previa, the pregnant women were divided into complete placenta previa (CPP) group, partial placenta previa (PPP) group and marginal placenta previa (MPP) group with each group 30 cases. Compare the pregnant women’s bleeding conditions like perioperative bleeding and blood transfusion, complications occurrence rate including placenta implantation, adherent placenta and puerperal infection as well as the delivery gestational weeks. Results The amount of perioperative bleeding and blood transfusion in the CPP group were obviously higher than the PPP group and MPP group (P<0.05). The amount of bleeding in the MPP group was the least (P<0.05). The amount of postpartum bleeding in the MPP group was middle which was significantly different with the PPP group (P<0.05). The total occurrence rate of complications in the CPP group was 83.3% which was significantly higher than the PPP group (30.0%) and MPP group (20.0%). The difference was significant. The premature delivery (<36 weeks) occurrence rate in the CPP group was 73.3% which was significantly higher than the PPP group (33.3%) and MPP group (10.0%). The difference was significant (P<0.05). All the comparison showed statistical significance (P<0.05). Conclusion Different types of placenta previa all cause injury to the mother’s body. And the clinical symptoms for complete placenta previa are significantly worse than partial placenta previa and marginal placenta previa with less gestational weeks.
