影响再植断肢成功率的重要因素为肢体缺血时间和保存方法。人们普遍认为断肢保存在低温环境能够耐受更长的缺血时间,将断肢浸入冰水中的低温保存方法虽简单,但冷却不充分,并且这种方法保存时间不宜超过6h。为延长肢体保存时间,我们探讨应用断肢的股动脉和股静脉与体外循环机相 Important factors that affect the success rate of replantation of severed limbs are limb ischemia time and preservation methods. It is generally believed that the preservation of amputated limbs in low temperature environment can withstand longer ischemic time, the cold limbs immersed in ice water is simple, but cooling is not sufficient, and this method should not be stored for more than 6h. In order to prolong the preservation time of limbs, we discuss the application of limbs femoral artery and femoral vein and cardiopulmonary bypass
