目的探讨子痫前期孕妇胎儿肾动脉血流动力学变化及临床意义。方法对120例正常孕妇及103例子痫前期孕妇胎儿的肾动脉(RA)进行彩色多普勒超声检测,记录两组胎儿肾动脉血流指标,测量并记录两组胎儿生长发育情况。结果子痫前期组胎儿肾动脉血流指标均高于对照组;重度子痫前期患者围产儿生长发育受限,肾动脉阻力指标增高,与对照组比较差异有统计学意义(P<0.05)。结论彩色多普勒超声可以用来观察子痫前期特别是重度子痫前期孕妇胎儿血流动力学变化,判定围产儿预后,为临床提供科学依据。
Objective To investigate the changes of fetal renal artery hemodynamics in pregnant women with preeclampsia and its clinical significance. Methods 120 cases of normal pregnant women and 103 cases of pregnant women with preeclampsia fetal renal artery (RA) were detected by color Doppler ultrasound, two groups of fetal renal artery blood flow index were recorded and recorded two groups of fetal growth and development. Results The indexes of fetal renal artery blood flow in preeclampsia group were higher than those in control group. The growth and development of perinatal children with severe preeclampsia were increased and the resistance index of renal artery was increased. The difference was statistically significant (P <0.05). Conclusion Color Doppler ultrasound can be used to observe the changes of fetal hemodynamics in preeclampsia, especially in severe preeclampsia, and to determine the prognosis of perinatal children, providing scientific evidence for clinical application.
