肢体离断后因缺血缺氧,正常的代谢过程受到干扰而产生一系列的病理生理变化,导致细胞变性和组织坏死.因此对断肢进行科学保存以减少组织缺血性损伤,延缓组织变性坏死,为临床赢得再植时间,显得尤为重要.本文通过检索分析相关文献,对保存断肢的几类常见方法做一综述,涉及低温保存法、器官保存液保存法、灌注保存法、高压氧保存法和暂时异位寄养再回植等.“,”Because of ischemia of severed limb, the normal metabolic processes are disturbed, resulting in a series of pathophysiological changes, leading to cell degeneration and tissue necrosis. So it is important to find a good way for preservation of severed limb. This article reviews the researches on ways and progress of preservation of severed limb. Kinds of hypothermic preservation, organic preservation solution, perfusion, hyperbaric oxygen and temporary ectopic implantation are included.
