０引言近年来彩色多普勒超声（ＣＤＦＩ）检测发现高原地区血压正常的妊娠妇女子宫动脉血流灌注有改变［１］，此血流动力学的变化可能影响高原缺氧出生婴儿的体重．我们对高原正常晚期妊娠和非孕期的子宫动脉内径、血流速度、阻力指数进行了测定，以了解胎儿血流动力学变... 0 Introduction In recent years, color Doppler ultrasound (CDFI) test found that normotensive uterine artery blood flow changes in normotensive pregnant women in the plateau [1]. This hemodynamic change may affect the body weight of neonates born with plateau hypoxia. We measured the plateau normal late pregnancy and non-pregnant uterine artery diameter, blood flow velocity, resistance index was measured in order to understand the fetal hemodynamics change ...
