再生育凶险性前置胎盘发生的高危因素分析

Analysis of Risk Factors Pernicious Placenta Previa for the Second Pregnant

目的对再生育凶险性前置胎盘(PPP)的主要高危因素进行调查分析。方法选取我院接诊的27例再生育凶险性前置胎盘孕妇为实验组,同期健康再生育孕妇30例为对照组,对其临床资料进行统计整理比较。结果实验组年龄、35岁以上比率、37周以下比率、孕次、宫腔手术次数、超过2次及上宫腔手术比率、产前出血率均高于对照组;孕周时间低于对照组,差异具有统计学意义(P<0.05);实验组产后出血量、输血量、术后住院时间、宫腔填塞率、子宫切除率、产后大出血率、输血率与胎盘植入率均高于对照组,差异具有统计学意义(P<0.05);两组子宫动脉结扎率对比,差异无统计学意义(P>0.05)。经多元回归分析,年龄、孕周、多次妊娠、产前出血史以及胎盘植入均是凶险性前置胎盘的高危因素(P<0.05)。结论产妇年龄、妊娠次数、子宫手术次数、产前出血史以及胎盘植入均是引起PPP的高危因素。

Objective The purpose of re birth of placenta previa （PPP） of the main risk factors. Methods 27 cases in our hospital before the birth of placenta previa pregnant women as the experimental group, healthy pregnant women give birth 30 cases as control group. The clinical data were compared for statistical analysis.Results The experimental group of age, over the age of 35 and 37 weeks following ratio ratio, times of pregnancy, intrauterine surgery times, more than 2 times and the ratio of uterine cavity operation, prenatal bleeding rate was higher than that of the control; gestation time is lower than the control group （P 〈 0.05）. The volume, blood transfusion volume, postoperative hospitalization time after postpartum hemorrhage in experimental group uterine packing rate, uterus resection rate, postpartum hemorrhage rate, blood transfusion rate and placenta implantation rate were higher than the control group （P 〈 0.05）, uterine artery ligation was no difference （P 〉 0.05）.Through multivariate regression analysis, age, gestational age, multiple pregnancy, prenatal bleeding history and placenta implantation are high risk factors of placenta previa （P〈 0.05）.Conclusion Maternal age, pregnancy times, the number of uterine surgery, the history of prenatal bleeding and placenta implantation were the high risk factors of PPP.
