摘　　要：目的　探讨高原环境对正常妊娠妇女子宫动脉血流及胎儿脐动脉血流变化的影响。方法　应用彩色多普勒超声诊断仪 ,测定高原地区 34例妊娠妇女和 37例非妊娠妇女的子宫动脉血流及 119例胎儿脐动脉血流参数 [收缩期与舒张期 (S/D)比值、阻力指数、子宫动脉内径、血流速度、血流量 ];并以平原地区妊娠及非妊娠妇女子宫动脉血流及胎儿脐动脉血流参数作对照。结果　高原及平原地区妊娠妇女的子宫动脉内径、血流量均有增加。高原地区妊娠妇女子宫动脉内径为 (0 35±0 0 4)cm、血流量为 (2 80± 48)ml/min ;平原地区妊娠妇女子宫动脉内径为 (0 45± 0 0 4)cm ,血流量为(4 2 5± 5 5 )ml/min ,两者比较 ,差异有极显著性 (P <0 0 1)。高原地区不同孕期的胎儿脐动脉血流速度、S/D比值、阻力指数均明显高于平原地区 ,两者比较 ,差异有极显著性 (P <0 0 1)。结论　高原环境对子宫动脉血流和脐血流均有一定影响 ,从而导致胎盘血流灌注减少。Objective To evaluate the effect of high altitude on uterine and umbilical artery blood flow dynamics during normal pregnancy Method Uterine artery blood flow parameters of the pregnant (34) and nonpregnant (37) subjects and umbilical artery blood flow parameters of 119 subjects living at high altitude or at low altitude were measured with color Doppler flow imaging system Results Uterine artery diameter, blood flow volume increased during pregnancy at both altitude, and uterine artery blood flow volume and diameter were smaller at high altitude than at low altitude [(0 35±0 04) cm vs (0 45±0 04) cm, (280±48) ml/min vs (425±55) ml/min, P <0 01] Umbilical artery blood flow velocity systolic to diastolic (S/D) value, resistant index of different pregnant period were greater at high altitude than at low altitude ( P <0 01) Conclusion High altitude has effect on placental and infant blood flow that causes the decrease of placental blood infusion and the increase of uterine and umbilical artery flow velocity S/D and reactive index
