彩色多普勒监测脐动脉血流速度在妊娠结局预测中的价值

The value of monitoring the speed of umbilical artery blood under color doppler in predicting pregnant outcome

目的研究彩色多普勒动态监测胎儿脐动脉血流速度（S/D值）与新生儿预后的关系。方法在1497例孕周为37~42周的产妇中筛查产妇的S/D值和记录新生儿脐血血气分析的结果。结果 S/D值高的产妇,分娩出的新生儿有更高的概率出现新生儿预后不良。结论脐动脉血流速度（S/D值）对围产期新生儿死亡及预后不良有重要意义。监测产妇S/D值在临床上有重要的实际意义。

Objective This article was to determine the value ofmeasuringthe umbilical artery blood flow systolic/diastolic （ S/D） ratio by color ultrasound in predicting neonatal outcome.Methods This study included 1497 pregnant women who get pregnant between 37 and 42 weeks.We measured the S/D ratio of umbilical cord and recorded the result of blood gas analysis of umbilical cord blood.Results The possibility of fetal distress was increased when the S/D ratios over 3.0.Conclusions Blood flow S/D ratios of the umbilical cord measured by color ultrasound have great significance in reducing the perinatal death and neonatal outcome.
