The volume flow in the calves was measured by means of plethysmography in 14 patients who had a cholecystectomy and in 3 patients who had a wedge biopsy of the breast. The blood flow increased 100% during abdominal surgery, while no change was observed during the extraabdominal operation. When the legs were placed horizontally during cholecystectomy clear signs of venous pooling were observed. Venous pooling in the calves increased when pillows were placed in the popliteal fossae to prevent over-stretching of the knees. Elevation of the legs 20 degrees in the hip joints decreased the venous stasis considerably. Except for intermittent effects on the circulation caused by strong retraction of the intestines, no clear-cut change in the degree of venous stasis was observed during the course of a cholecystectomy.
通过体积描记法测量了14例接受胆囊切除术的患者和3例接受乳房楔形活检的患者小腿的容积流量。腹部手术期间血流增加了100%，而腹部外手术期间未观察到变化。胆囊切除术中当腿部水平放置时，观察到明显的静脉淤积迹象。当在腘窝处放置枕头以防止膝盖过度伸展时，小腿的静脉淤积增加。髋关节将腿部抬高20度可显著减少静脉淤滞。除了因强力牵拉肠道对循环产生的间歇性影响外，在胆囊切除过程中未观察到静脉淤滞程度有明显变化。
