在人类,不同运动级别对子宫胎盘和胎儿循环的影响,医学文献尚无满意的回答。运动时和运动后测量子宫血流已在动物模型进行过。然而,人类妊娠时,不使用损伤性或同位素技术很难获得运动时子宫胎盘血流变化的信息。使用连续波多普勒超声评估子宫胎盘循环,能提供来自子宫动脉周围血管床阻力的信息,是测量子宫胎盘循环血流的主要方法之一。本研究采用上述方法对20例无合并症健康单胎妊娠妇女进行研究,平均年龄25±4岁,平均孕龄
In humans, different levels of exercise on the uterine placenta and fetal circulation, the medical literature is still no satisfactory answer. Measurement of uterine flow during and after exercise has been performed in animal models. However, it is difficult to obtain information on changes in placental blood flow in uterus during exercise without damaging or isotope techniques in human pregnancy. Using continuous wave Doppler ultrasound to evaluate uteroplacental circulation, which provides information on vascular bed resistance around the uterine artery, is one of the major methods of measuring uteroplacental circulating blood flow. In this study, 20 cases of healthy singleton pregnancy women without complications were studied with the mean age of 25 ± 4 years, mean gestational age
