胎儿血流动力学检测与胎儿窘迫的相关性分析

目的 研究胎儿血流动力学检测与胎儿窘迫的相关性。方法对60例宫内窘迫胎儿脐动脉和大脑中动脉的收缩期峰值（s）／舒张末期血流速度（D）比值（S／D），阻力指数（RI）、搏动指数（PI）进行了测量，以同期相同孕周正常产妇作为对照。结果宫内窘迫胎儿大脑中动脉各项阻力指标均低于正常组，而脐动脉各项阻力指标均高于正常组。结论：通过对胎儿大脑中动脉及脐动脉血流动力检测，可以早期发现胎儿宫内低氧状态，并为临床治疗提供依据和参考。

Correlation between the detection of fetal hemodynamics and fetal distress

Objective To study the relation between the detection of fetal hemodynamics and fetal distress. Methods Measure the ratio of peak of systolic and the blood velocity of the late phrase of diastolic （S/D） on the umbilical artery （UA） and mean cerebral artery （MCA） , resistance index （ RI ）, pulse index （ PI ） on 60 cases of fetals with intrauterine dis- tress,and compare with those of healthy pregnants at the same gestation. Results Every measurement of resistance on the mean cerebral artery in intrauterine distress fetals was lower than that of normal group,while every measurement of resistance on umbilical was higcr than that of normal group. Conclusion Detecting the hemodynamics of UA and MCA in the fctals, we could decide whether the fetals in the uterus was in the state of low oxygen at an early stage,which could be the reference for appropriate clinical treament.
