摘　　要：目的:介绍应用彩色多普勒超声(CDU)技术观察102例胎儿宫内缺氧孕妇氧疗前后的脐动脉和大脑中动脉的血流动力学变化,评价氧疗的临床价值。方法:比较36例宫内生长迟缓(IUGR)胎儿,66例脐带绕颈(UCAN)胎儿氧疗前后血流动力学变化,以脐动脉阻力指数(RIUA)和大脑中动脉阻力指数(RIMCA)及RIMCA/RIUA为分析指标。结果:氧疗前后,IUGR组RIUA及RIMCA变化差异有统计学意义(P<0.05,P<0.01);UCAN组仅RIMCA变化差异有统计学意义(P<0.05)。结论:氧疗可改善胎儿血液循环和供氧,CDU为宫内缺氧胎儿氧疗疗效观察提供了重要依据。Objective： To study the change of the color Doppler uhrasound （CDU） prior and poster oxygen treatment in 102 fetus with intrauterine hypoxia, and to evaluate the Value of oxygen treatment. Methods： To compare the hemodynamics change of umbilical artely and fetal middle cerebral arlery in 36 cases of intrauterine growth retardation （IUGR） and 66 cases of umbilical cord around neck （UCAN） prior and poster oxygen treatment, umbilical artery resistance index （RIUA）, fetal middle cerebral artery resistance index （RIMCA ） and RIMCA/RIUA were analyzed. Results ： Prior and poster oxygen treatment,RIUA and RIMCA were all significantly different （P 〈 0. 05） in IUGR group, however, in UCAN group, only the RIMeA was significantly changed （P 〈0. 05） . Conclusion： The oxygen treatment may improve the fetal circulation and oxygen supply. CDU can provide an important method for the monitoring of intrauterine hypoxia in fetus after oxygen treatment.
