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。
Objective To 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 resistance ） 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.
