摘要
目的探讨胎心监测联合脐血流测定对预测妊娠晚期胎儿宫内健康状况及预后的临床价值。方法对264例孕妇联合进行胎心监测无负荷试验及胎儿脐动脉血流测定(S/D比值),对胎儿宫内状况作出分析评价并追踪观察。结果胎心监护异常组有42.0%的新生儿预后不良,剖宫产率达60.0%,明显高于胎心监护正常组(P<0.01);脐血流S/D值≥3组有47.2%的新生儿预后不良,剖宫产率达69.4%,明显高于S/D值<3组(P<0.01);胎心监护、脐血流测定的阳性预测率分别为42.0%和47.2%,二者联合测定的阳性预测率高达70.8%,明显高于单项检查预测值。结论脐血流与胎心监护联合应用能提高胎儿宫内状况异常的诊断率,早期发现胎儿窘迫,改善胎儿预后。
Objective To explore the clinical value of fetal heart rate monitoring combined with umbilical ar- tery blood flow monitoring for late trimester of preg- nancy and prognosis. Methods 264 cases of pregnant women received fetal heart nonstress test and measur-ing of umbilical artery blood flow and the fetal intrauterine growth was observed. Results 42. OK of new- borns in the abnormal fetal heart rate group showed bad prognosis and the rate of cesarean delivery was 60.0%, which was higher than that in the normal fetal heart rate group（ P %0.01）. 47.2% of newborns showed bad prognosis, in the umbilical artery blood flow S/D≥3 group and the rate of cesarean delivery was 69.4%, which is higher than that in the S/D〈3 group. The positive prediction rates confirmed by fe- tal heart rate monitoring and umbilical artery blood flow monitoring were 42.0% and 47.2% respectively, and the combined positive prediction rate was 70. 8%. Conclusion Fetal heart rate monitoring combined with umbilical artery blood flow monitoring can improve the accuracy of diagnosing fetal intrauterine growth to discover fetal distress early and can contribute to fetal prognosis.
