多普勒超声检测胎儿脐动脉血流S/D、RI值对于评价宫内窘迫的临床意义

Detected by Color Doppler Ultrasound of S/D、RI of Umbilical Artery Blood Flow Evaluation of Fetal Distress and Its Clinical Application Value

目的：通过多普勒超声检测晚期妊娠胎儿脐动脉血流S／D、RI值，探讨其对于评价宫内窘迫的临床价值，对于预测围生儿预后的意义。方法对180例孕32～41周单胎孕妇采用彩色多普勒超声进行产前检查，观察胎儿有无脐带绕颈、羊水透声、测定脐动脉S／D、RI值，根据检查结果分为脐带绕颈组和无脐带绕颈组，观察两组胎儿宫内窘迫的发生率；发生胎儿宫内窘迫与无宫内窘迫脐动脉血流S／D、 RI值的差别；以及胎儿脐动脉血流与妊娠预后的关系。结果与无脐带绕颈组相比，脐带绕颈组胎儿宫内窘迫发生率高（ P＜0．05）；发生胎儿宫内窘迫脐动脉血流S／D、RI值明显高于无胎儿宫内窘迫者（ P＜0．05）。脐动脉血流正常者剖宫产率、羊水污染及Apgar 评分＜7明显高于异常者（ P＜0．05）。结论多普勒超声检测胎儿脐动脉血流对评价胎儿宫内窘迫、预测围生儿预后有重要的临床应用价值。

Objective Detection of pregnancy by ultrasound fetal umbilical artery , explore the correlation with the occurrence of fetal distress , analyze the clinical value of its prediction of perinatal prognosis children .Methods 180 ca-ses of 32~41 weeks of single pregnant women by color doppler flow imaging （cdfi） for antenatal examination, to observe fetal umbilical cord around the neck , amniotic fluid acoustic , determination of umbilical artery S/D, RI value, divided into umbilical cord around the neck and umbilical cord around the neck group according to the test results , observe differ-ence of fetal distress incidence;umbilical artery blood flow S/D, RI value of fetal intrauterine distress and no intrauterine distress;And the relationship between fetal umbilical artery blood flow and pregnancy outcomes .Resu lts compared with the group without umbilical cord around the neck , fetal distress rates in umbilical cord around the neck group is higher （ P〈0.05 ）;Fetal intrauterine distress umbilical artery blood flow S /D, RI values were significantly higher than those without fetal distress （P〈0.05）.Cesarean section rate, amniotic fluid contamination and Apgar score 〈7 of Umbilical artery blood flow who normal is significantly higher than abnormal （P〈0.05）.Conclu sions Detected by color Doppler ultrasound of umbilical artery blood flow evaluation Of fetal distress and predict the perinatal prognosis have important clinical value.
