摘　　要：目的 :探讨脐动脉血流搏动指数(PI)值联合胎盘体积在评估早发型子痫前期(PE)中的应用。方法 :选取100例早发型PE作为早PE组,同期选取正常妊娠妇女100例作为正常组,所有研究对象于孕18~20周均检测脐动脉血流PI值及胎盘体积,分析两者对早发型PE的评估价值。结果:早PE组脐动脉血流PI值明显高于正常组,且胎盘体积明显低于正常组(均P<0.05);ROC曲线结果显示,脐动脉血流PI值以>1.00为临界值时,评估早发型PE发生的敏感度、特异度、准确度分别为86.00%、84.00%、85.00%,胎盘体积以<68.50 cm3为临界值时为82.00%、78.00%、80.00%,两者联合时为96.00%、94.00%、95.00%,两者联合均明显高于两者单独应用(均P<0.05),两者单独比较,差异无统计学意义(P>0.05)。结论:脐动脉血流PI值、胎盘体积与早发型PE的发生有关,检测两者水平有利于该病的评估,且两者联合时具有更高的评估效能,值得进一步推广。Objective：To discuss the application of the umbilical artery（UA） blood flow pulsation index（PI） value combined with the placental volume in the assessment of early onset preeclampsia（EOSP）. Methods：100 patients with EOSP were selected as the experimental group,100 normal pregnant women were selected as normal group at the same time. All the subjects were given ultrasound examination of UA blood flow PI value and placental volume in the 18~20 weeks of pregnancy,and the values of the two groups were evaluated. Results：The UA blood flow PI value of experimental group was significantly higher than that of normal group,the placental volume of experimental group was significantly lower than that of normal group,the differences were statistically significant（all P〈0.05）. The ROC curve showed that,when the PI value of umbilical artery blood flow was 1.00,the sensitivity,specificity and accuracy of evaluation of EOSP were 86.00%,84.00% and 85.00% respectively. Choosing the placental volume with 68.50 cm3 as critical,the ratios were 82.00%,78.00%,80.00% respectively; and 96.00%,94.00%,95.00%for the combination of the two methods. The ratios of the combination of the two methods were significantly higher than those of the two alone,the differences were statistically significant（P〈0.05）. There were no significant differences between the two groups（P〈0.05）. Conclusions：UA blood flow PI value and placental volume are related to the occurrence of EOSP,detection of the two level is helpful to evaluate the occurrence of the disease,and the combination of the two methods has higher evaluation efficiency. It＇s worth for further clinical promotion.
