摘　　要：目的:探讨孕晚期脐血流动脉收缩压/舒张压(S/D)值与胎心无应激试验(NST)在评价胎儿预后中的意义。方法:通过对82例孕晚期孕妇进行NST,同时测定胎儿脐血流S/D值,记录分娩结局,并结合临床进行分析。结果:S/D≥3组中NST可疑型和无反应型的发生率均显著高于S/D<3组(均P<0.01);S/D≥3组围产儿预后不良的发生率较S/D<3组显著增高(P<0.05,P<0.01);脐血流S/D值与NST联合监测胎儿预后不良的阴性预测值、阳性预测值、特异度、敏感度分别为94.44%,89.29%,94.44%和89.29%。结论:监测脐血流S/D值联合NST可作为评价胎儿宫内安危的一种有效方法。Objective：To discuss the clinical significance of umbilical artery blood systolic/diastolic（S/D）ratio and fetal heart non-stress test（NST）in evaluation prognosis of fetus.Methods：NST results and umbilical artery blood S/D ratio in 82 pregnancy women were determined,and analyzed with clinical symptom.The end results of deliver were recorded.Results：The suspect type and non response type of NST in group S/D≥3 were significantly higher than group S/D〈3（P〈0.01）.The incidence rate of fetal unfavourable prognosis in group S/D≥3 was significantly higher than group S/D〈3（P〈0.05）.The negative predictive value,positive predictive value,specificity and sensitivity in fetus of unfavourable prognosis by using monitor umbilical artery blood S/D ratio and NST were 94.44%,89.29%,94.44% and 89.29%.Conclusion：Monitoring umbilical artery blood S/D ratio and NST are effective methods in evaluation prognosis of fetus safe.
