止血带充气后8分钟细腻线粒体内的氧分压降为零，以而引起无氧代谢。在T道后的30—60分钟内。烟酰胺腺嘌呤二酸（NAD）降低，磷酸肌酸酶明显增高且在肌肉中积蓄，很快产生细胞内酸中毒缺氧和酸中离导致肌红蛋白、细胞内酶和钾离子的释放.如果止血带时间钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具  超过60分钟，血管内皮完整性受到损害，会产生组织水肿，以致切口缝合困难.随时间延长肢体温度下降，可与室温相同。由于止血带下面的肌肉受压，可能延迟病人康复。
8 minutes after tourniquet inflation, the oxygen pressure drop in fine mitochondria was zero, which caused anaerobic metabolism. Within 30-60 minutes after t-channel. Nicotinamide adenine diacid (NAD) is decreased, creatine phosphocreatine enzyme is significantly increased and accumulated in muscle, which leads to intracellular acidosis. Hypoxia and acidolysis lead to the release of myoglobin, intracellular enzymes and potassium ions. If the tourniquet time is more than 60 minutes, vascular endothelial integrity will be damaged, resulting in tissue edema, which makes the incision suture difficult It can be the same as room temperature. Recovery may be delayed due to compression of the muscles under the tourniquet.
