羊水过多胎儿血流变化的临床研究

Changes in fetal blood flow of polyhydramnios

目的 探讨羊水过多胎儿血流的变化。方法 对13例足月妊娠羊水过多应用彩色多普勒显像技术(CDFI)检测胎儿肾动脉,大脑中动脉的搏动指数(PI)、阻力指数(RI)以及脐动脉S/D值,并选择13例正常羊水量足月妊娠作为对照组,t检验比较两组间肾动脉、大脑中动脉的血流参数和济动脉S/D值。结果 羊水过多胎儿肾动脉PI、RI明显高于正常羊水量对照组(P<0.05);大脑中动脉PI、RI,脐动脉S/D值两组比较无显著差异(P>0.05)。结论 羊水过多与胎儿肾动脉血流有明显相关性,其胎儿肾动脉血流阻力改变在羊水过多中的意义有待于进一步研究。

Purpose Explore Ithe changes in fetal blood flow of polyhydramnios. Methods The pusaility index(PI) and the resistence index (RI) of the fetal renal artery, middle cerebral artery and S/D rsatio of umbilical artery of 13 term pregnant women were measured by color Doppler flow imaging(CDFI), compared with those of the same gestational age and normal amniotic fluid volume. Results The PI and RI of the fetal renal artery were obviously higher than the control group. (P < 0.05) Conclusion It is significantly that polyhydramnios correlated to the fetal renal artery flow.
