目的:探讨凶险性前置胎盘的围手术期的高危因素及应对策略.方法:对127例凶险性前置胎盘的病例产前出血、术中出血、围手术期出血、子宫切除率、及其他母儿严重并发症进行分析.根据前置胎盘类型分为:中央性前置胎盘组与部分行前置胎盘组.根据术中胎盘剥离情况分为:胎盘植入组、胎盘粘连组及正常剥离组.结果:(1)胎盘植入率:中央组为49.5%,明显高于部分组胎盘植入率23.1%(P<0.05).(2)围手术期出血:中央组平均为1 800 m L,高于部分组平均1 128 m L(P<0.01).胎盘植入组平均2 636 m L,胎盘粘连组平均1 342 m L,胎盘正常剥离组平均822 m L,各组间均有统计学差异(P<0.01).(3)输血情况:胎盘植入组有98.2%患者术后接受输血治疗,平均输血量2 255 m L,胎盘粘连组有88.2%患者接受输血,平均1 267 m L,正常剥离组有53.7%患者接受输血,平均1 165 m L,胎盘植入组明显高于粘连组(P<0.05)及正常剥离组(P<0.01),而粘连组与正常剥离组比较无统计学差异(P>0.05).(4)子宫切除情况:中央组为34.7%,高于部分组15.4%(P...

Aim: To evaluate the risk factor of percinious placenta previa and to explore the strategies of management. Methods: The data of 127 patients with percinious placenta previa were studied. Blood loss,blood transfusion in and peri operation,the rate of hysterectomy,and other serious complications of maternals and neonates were analyzed. The patients were divided into two groups: completed placenta previa( CPP) group and partial placenta previa group( PPP). Based on the separation of the placenta from the uter...
