Eleven healthy male volunteers were studied to determine the amount of blood displaced by the inflation of the antishock trousers (AST) at pressures of 40 and 100 mm Hg. Radioisotope scans were used to determine the blood volume distribution and the change in the volume of distribution with inflation of the AST. The volunteers were then phlebotomized approximately one liter of blood and the study was repeated. Less than 5% of the total blood volume was displaced with inflation of the AST. It is unlikely that the clinical improvement seen with inflation of the AST in hypovolemic shock is due to autotransfusion of blood alone.
对11名健康男性志愿者进行了研究，以确定抗休克裤（AST）在40和100毫米汞柱压力下充气时所排出的血液量。使用放射性同位素扫描来确定血容量分布以及随着AST充气时分布容积的变化。然后对志愿者进行静脉放血约一升，并重复该研究。AST充气时所排出的血液量不到总血容量的5%。低血容量性休克时AST充气所带来的临床改善不太可能仅归因于血液的自身输血作用。
