| 摘 要： | 目的:监测胎儿大脑中动脉、肾动脉血流阻力指标与胎儿宫内缺氧关系。方法:回顾分析200例晚孕孕妇(孕龄>35周,平均38周),探讨胎儿宫内缺氧与胎儿脑、肾动脉阻力之间的关系。结果:胎儿大脑中动脉、肾动脉S/D、PI、RI(三者简称阻力指数),在宫内缺氧的胎儿,大脑中动脉阻力指教降低显著,而肾动脉阻力指数增高明显。若以大脑中动脉S/D<4,PI<1.6,RI<0.6;肾动脉S/D>5,PI>1.9,RI>0.8预测胎儿宫内缺氧有明显的临床实用价值。结论:彩色多普勒监测胎儿大脑中动脉,肾动脉阻力指数,对预测胎儿宫内缺氧有一定的临床意义。

| Abstract: | ObjectiveTo study the relationship between fetal intrauterine hypoxia and the blood resistance of MCA and RA. Methods Total of 200 pregnant women with gestation age>35 weeks were examined.Results S/D、PI、RI(the blood resist- ance)of MCA and RA were measured by prenatal color Doppler ultrasound.Resultsin fetal of intrauterine hypoxia,S/D、PI and RI of MCA were decreased significantly;S/D,PI and RI of RA were ascreased significantly.Fetal intrauterine hypoxia was indicated as S/D<4,PI<1.6,RI<0.6 in MCA and S/D>4,PI>1.9,RI>0.8 in RA.Conclusion Monitoring the blood resistance of MCA and RA could play essential role in predicting the status of fetal intrauterine hypoxia earlier. |
