Cardiac output, central pressures and leg blood flow wre studied in a group of nine young individuals undergoing surgery for varicose veins. These subjects did not differ from older ones in an earlier, corresponding study in respect of central or femoral blood flow. The haemodynamic affects of peroperative variations of the blood volume were also the same. Thus, the common femoral arterial blood flow decreased by 40% from a mean of 450 to 260 ml/min during the operation. After transfusion of 900 ml of blood the flow increased to 575 ml/min. As a low blood predisposes to thrombosis, it is concluded that, irrespective of age, adequate peroperative volume substitution is of great importance in counteracting such a risk.
对一组9名接受静脉曲张手术的年轻个体的心输出量、中心压力和腿部血流进行了研究。在早期一项相应研究中，这些受试者在中心血流或股血流方面与年龄较大者并无差异。术中血容量变化的血流动力学影响也是相同的。因此，在手术过程中，股总动脉血流从平均450毫升/分钟降至260毫升/分钟，减少了40%。输注900毫升血液后，血流增加至575毫升/分钟。由于低血容量易引发血栓形成，得出结论：无论年龄大小，术中进行充足的容量替代对于抵消此类风险非常重要。
