The velocity of venous blood flow in the legs has been measured in patients before and after operation using I hippuran. Immediately after operation there was a profound slowing of venous flow to about half the pre-operative rate. On the day following operation the rate had returned to the pre-operative level. The effect of elevation of the legs has been investigated. Leg elevation approximately doubled the rate of flow. The value of leg elevation as a measure in the prevention of deep vein thrombosis is discussed in the light of these findings. The paper provides evidence that the practice of elevation of the legs during and after operation increases venous flow rate.
使用碘马尿酸对患者术前和术后腿部静脉血流速度进行了测量。术后立即出现静脉血流显著减慢，降至术前速度的约一半。术后第一天，血流速度恢复到术前水平。对抬高腿部的效果进行了研究。抬高腿部使血流速度大约增加了一倍。根据这些发现，讨论了抬高腿部作为预防深静脉血栓形成措施的价值。本文提供了证据，证明手术期间及术后抬高腿部的做法可提高静脉血流速度。
