胎儿窘迫时,变化最敏感的血流动力学指标是全身血流分布量的改变,以保证重要器官功能不受过多损伤。脐动脉(UA)为单一器官的供给血量,其某一动脉的血流变化不能反映全身血流动力学的分布状况。采用彩色多普勒监测胎儿窘迫时UA血流的S/D值、RI值、PI值,探讨其三者的相关性和围产儿结局的关系,现分析报告如下。 资料与方法 1.研究对象:1997年10月至1999年10月,在我院产前检查及住院孕妇,胎儿窘迫100例为窘迫组,孕周37～41周,年龄23～33岁。另选择正常妊娠100例,为对照组,孕周25～41周,年龄23～35岁。两组均为单胎、头位、初产妇。
Fetal distress, the most sensitive change in hemodynamic indicators of systemic blood flow changes in the amount of distribution, in order to ensure that vital organ function is not excessive damage. Umbilical artery (UA) is the supply of blood to a single organ, and changes in the blood flow of one of its arteries do not reflect systemic hemodynamics. Color Doppler UF flow monitoring of fetal distress S / D value, RI value, PI value, to explore the relationship between the three and the relationship between perinatal outcome, the report is as follows. Materials and Methods 1. Subjects: Between October 1997 and October 1999, prenatal care and hospitalized pregnant women were included in our hospital. 100 cases of fetal distress were embarrassed group. The gestational age ranged from 37 to 41 weeks and ranged from 23 to 33 years. Another 100 cases of normal pregnancy, control group, gestational age 25 to 41 weeks, aged 23 to 35 years. Both groups were single-child, head position, primipara.
