目的探讨多普勒超声检测脐动脉血流对胎儿宫内窘迫的临床意义。方法对我院2015年6月至2016年6月200例分娩孕妇进行彩色多普勒超声产前检查,根据检查结果分为两组,胎儿脐带绕颈(窘迫组)以及胎儿无脐带绕颈组(无窘迫组),观察两组胎儿宫内窘迫发生率,脐带、羊水、脐带血流动力学指标,记录并发症情况。结果发生脐带绕颈的胎儿宫内窘迫发生率高于无脐带绕颈胎儿,发生窘迫组孕妇RI、S/D,均高于对照组,窘迫组分娩孕妇在第一、第二产程时间较无窘迫组分娩孕妇分娩时间较长。窘迫组新生儿窒息、脑缺氧、死产等发生率明显高于无窘迫组,且差异具有统计学意义(P<0.05)。结论多普勒超声检测胎儿脐动脉血血流动力学指标有助于预测胎儿宫内窘迫情况,具有重要的临床价值。
Objective To investigate the clinical significance of Doppler ultrasound in detecting umbilical artery blood flow in fetal distress. Methods A total of 200 prenatal pregnant women in our hospital from June 2015 to June 2016 were examined by color Doppler sonography. According to the results of the examination, the patients were divided into two groups. The fetal umbilical cord around the neck (distress group) and fetal umbilical cord around the neck group (No distress group). The incidence of fetal distress, umbilical cord, amniotic fluid and umbilical cord hemodynamics were observed and the complications were recorded. Results The incidence of fetal distress around the umbilical cord around the neck was higher than that of the umbilical cord around the neck. The RI and S / D of the pregnant women in the distress group were higher than those in the control group. Distress group delivery pregnant women delivery time longer. The incidence of neonatal asphyxia, cerebral hypoxia and stillbirth in distress group was significantly higher than that in non-distress group (P <0.05). Conclusion Doppler ultrasound detection of fetal umbilical artery hemodynamics index is helpful to predict the situation of fetal distress, and has important clinical value.
