摘　　要：目的探讨彩色多普勒超声对胎儿宫内缺氧的诊断价值。方法选择在我院进行胎儿检查的150例孕妇作为研究对象，确诊存在胎儿宫内缺氧的孕妇为观察组（n=69），胎儿发育正常的孕妇为对照组（n=81），两组孕妇均采用彩色多普勒超声进行诊断，比较两组孕妇胎儿大脑中动脉和脐动脉的阻力指数（RI）、搏动指数（PI）、及收缩期与舒张期流速比（S／D）。结果观察组胎儿大脑中动脉的RI、PI及S／D值均低于对照组（P〈0．05）；观察组胎儿脐动脉的RI、PI及S／D值均高于对照组（P〈0．05）；比较观察组不同孕周的RI、PI及S／D值，差异具有统计学意义（P〈0．05）结论利用彩色多普勒超声对孕妇胎儿大脑中动脉与脐动脉的RI、PI、S／D进行检测，对孕妇胎儿宫内缺氧的情况有较高的诊断价值。Objective To investigate the clinical value of color Doppler ultrasonography in the diagnosis of intrauterine hypoxia. Methods A total of 150 cases of pregnant women examined in our hospital were selected as research objects, the pregnant women confirmed intrauterine hypoxia were setted as observation group （n=69）, and the healthy pregnant women were setted as control group （n=81）. Both of two groups were diagnosed by color Doppler uhrasonography, and the RI, PI and S/D in middle cerebral artery and umbilical artery of two groups were compared. Results The RI, PI and S/D of middle cere- bral artery in the observation group were lower than those in the control group （P〈0.05）; the RI, PI and S/D of umbilical artery in the observation group were higher than those in the control group （P〈0.05）; the RI, PI and S/D of the observation group in different gestational age, the differences were statistically significant （P〈0.05）. Conclusion Using color Doppler ul- trasonography to detect the RI, PI and S/D of middle cerebral artery and umbilical artery in pregnant women, which has high diagnosis value of intrauterine hypoxia.
