报道孕满３６周至４２周的孕妇６１例同时接受无刺激试验（ＮＳＴ）、声刺激试验（ＶＳＴ）和脐动脉血流参数测定（Ｓ／Ｄ，ＲＩ，ＰＩ）的结果。指出，ＮＳＴ与ＶＳＴ结果无显著差异，Ｐ＞０．０５；ＮＳＴ与Ｓ／Ｄ结果相比，有显著差异，Ｐ＜０．０５。ＮＳＴ或ＶＳＴ异常组与Ｓ／Ｄ异常组中宫内窘迫发生率无显著差异，Ｐ＞０．０５。脐动脉血流参数与胎儿宫内窘迫、脐带缠绕关系密切，Ｐ＜０．０５。认为临床上可考虑以ＶＳＴ代替ＮＳＴ，且有缩短操作时间等优点。多普勒超声测定脐动脉血流参数对脐带缠绕等血流阻力增加因素的预测有重要参考价值，三者联合使用可提高对胎儿急慢性宫内窘迫诊断的准确性。
Reported 61 pregnant women of 36 weeks pregnant to 42 weeks pregnant women were simultaneously subjected to the results of NST, VST and S / D, RI and PI. Pointed out that NST and VST results no significant difference, P> 0.05; NST and S / D results, there was a significant difference, P <0.05. The incidence of intrauterine distress in NST or VST abnormal group and S / D abnormal group had no significant difference (P> 0.05). Umbilical artery blood flow parameters and fetal distress, umbilical cord wound closely, P <0.05. That clinically considered to replace the NST VST, and shorten the operation time and so on. Doppler ultrasound measurement of umbilical artery blood flow parameters such as umbilical cord blood flow resistance increases the prediction of an important reference value, the three combined use can improve the accuracy of fetal diagnosis of acute and chronic intrauterine distress.
