【摘要】：目的探讨凶险型前置胎盘发病的影响因素及围生期结局分析。方法回顾分析2011年1月至2015年12月在百色市两所三甲医院住院分娩的143例凶险型前置胎盘孕产妇(研究组)和286例非凶险型前置胎盘孕产妇(对照组)的临床资料。结果研究组孕产妇的平均年龄高于对照组(t=2.92,P=0.004);研究组孕产妇既往孕次、既往产次、既往流产次数、既往剖宫产次数、既往前置胎盘发生率均高于对照组(P0.01),研究组孕产妇的既往前置胎盘发生率高于对照组(χ2=7.60,P=0.006);研究组孕产妇的产前孕周小于对照组(t=-12.33,P0.01)。多因素分析显示,年龄、既往流产次数、既往剖宫产次是发生凶险型前置胎盘的影响因素,其中既往剖宫产次是3个影响因素中最主要的危险因素。研究组的产前出血发生率、产后出血发生率、子宫切除率、早产儿发生率均高于对照组(P0.01);研究组的术中出血量均高于对照组(P0.05);研究组的新生儿体质量和新生儿1min Apgar评分等均低于对照组(P0.05)。结论年龄、既往流产次数、既往剖宫产次与凶险型前置胎盘的发生有关。
[Abstract]:Objective to investigate the risk factors and perinatal outcome of severe placenta previa. Methods A retrospective analysis of 143 cases of hospitalized delivery in two third Class A Hospitals in Baise City from January 2011 to December 2015 was carried out. Type I placenta previa (. Results the average age of pregnant women in the study group was higher than that in the control group (2.92). P0. 004; The incidences of pregnancy, delivery, miscarriage, cesarean section and placenta previa in the study group were higher than those in the control group (P 0.01). The incidence of placenta previa in the study group was higher than that in the control group (蠂 2 7.60 P < 0.006). The prenatal and gestational weeks in the study group were smaller than those in the control group (P 0.01). Multivariate analysis showed that the age and the number of previous miscarriages were higher than those in the control group. The previous cesarean section was the most important risk factor among the three influencing factors. The incidence of prenatal hemorrhage and postpartum hemorrhage in the study group was the most important factor. The rate of hysterectomy and the incidence of premature infants were higher than those of the control group (P 0.01). The amount of intraoperative bleeding in the study group was higher than that in the control group (P 0.05). The body weight of newborn and the Apgar score of newborn in the study group were lower than those in the control group (P 0.05). Conclusion the age and the number of previous miscarriages were lower than those of the control group. Previous cesarean section was associated with the occurrence of dangerous placenta previa.

【正文快照】： 凶险型前置胎盘是指前次有剖宫产史,此次妊娠为前置胎盘,发生胎盘植入的危险约50%[1]。最早由Chattopadhyay等[2]提出。凶险型前置胎盘常伴有胎盘植入,极易导致妊娠晚期出血和造成难治性产后大出血,因此它是造成围生期孕妇发病率和死亡率的主要原因之一[3]。目前,由于剖宫产率
