The blood flow to the calves during abdominal surgery under different kinds of general anaesthesia was measured by strain gauge plethysmography in 12 patients. The volume flow increased 100% during surgery in both light and deep anaesthesia, caused by a decrease in peripheral resistance. The increase in volume flow could partly be explained by the anaesthesia itself, possibly induced by the use of a nitrous oxide-oxygen gas mixture. The surgical procedure caused a further increase in volume flow. Possible underlying mechanisms are discussed.
通过应变计体积描记法对12例患者在不同种类全身麻醉下腹部手术期间小腿的血流情况进行了测量。在浅麻醉和深麻醉期间,由于外周阻力降低,手术过程中血流体积均增加了100%。血流体积的增加部分可由麻醉本身解释,可能是使用氧化亚氮 - 氧气混合气体所致。手术操作使血流体积进一步增加。文中讨论了可能的潜在机制。
