摘　　要：[目的 ]　应用胎儿脐动脉血流S/D值监测≥孕 36周住院孕妇 ,观察S/D值≥ 3时 ,对新生儿窒息和发生高危妊娠的临床意义。 [方法 ]　对 15 10例临床资料用脐血流S/D值 ,与胎心电监护 (NST)和B超羊水量的测定进行分析比较。 [结果 ]　脐血流S/D值≥ 3组对新生儿窒息的阳性符合率均高于NST无反应组和B超异常组 (P <0 .0 0 5 )。S/D值 (≥ 3和 <3)两组中发生高危妊娠率比较差异有显著性 (P <0 .0 0 5 )。 [结论 ]　脐血流S/D值检测是一种对母婴无损伤的有效监测手段 ,弥补了单纯用NST或B超预测判断新生儿窒息的不足 。Objective To reveal the clinical significance of the relationship between the umbilical artery flow velocity S/D ratio and neonatal asphyxia and the high risk pregnancy for pregnancies beyond 36 weeks of gestation. [Methods] S/D ratio, nonstress test(NST) and aminiotic fluid volume estimated by ultrasongraphy of 1510 cases of the pregnant women were used for analysis and comparison. [Results] More neonatal asphyxia occurred in S/D ratio ≥3 group than that in NST nonreactive group or ultrasonography abnormal group, difference significant (P<0.005). Rate of high risk pregnancy differed in groups with S/D ratios ≥3 and <3, difference significant(P<0.005). [Conclusion] The measure of S/D ratio is a nonharmful efficient method, which may help to determine neonatal asphyxia when NST or ultrasonography failed. When combined with NST and ultrasonography adds the reliability of supervision of fetus.
