近 10ａ年来 ,应用彩色多普勒血流显像探查脐动脉并用脉冲多普勒测定胎儿脐动脉血流阻力 ,以了解胎儿宫内状况 ,在临床中对及时发现胎儿异常起着极其重要的作用。本文对近 2ａ自觉有胎动减少的晚期妊娠实施了胎儿脐动脉血流测定 ,并同时对胎儿预后进行观察。1　资料和方法1 1　 In the recent 10 years, color Doppler flow imaging was used to probe umbilical artery and pulse Doppler to measure fetal umbilical artery blood flow resistance in order to understand the intrauterine conditions. It plays an extremely important role in the timely detection of fetal abnormalities . In this paper, fetal umbilical artery blood flow measurement was performed on nearly two-thirds of pregnant women who had consciously had a decrease in fetal movement. At the same time, their prognosis was observed. 1 Materials and Methods 1 1
