高原环境上肢止血带耐受性观察分析

目的：为探讨高原环境对肢体耐受止血能力的影响。方法：在高原环境下，对17例志愿者的前臂和上臂分别置止血带， 观察其耐受性。结果：（1）高原环境下肢体对止血珲缺血耐受能力明显降低，耐受止血带平均较上臂明显缩短。结论：在高原环境下，应严格控制止血带时限和压务，密切观察全身系统和肢体局部变化，防止止血带并发症发生。

GENERAL TOTERANCE EFFECTS OF UPPER LIMB ON TOURNIQUET PRESSURE UNDER MOUNTAIN ENVIRONMENT

To observe the general tolerance effects of tourniquet on upper limb under high altitude environment.Method:17 healthy volunteers received an uppeer extremity tourniquet tweak at altitude of 3 654m and the BP, heart rate and general express were observed before performance and each 5 minutes progress.Results:The upper limb tolerance was obviously decreased compared with that in sea level and there is a great difference between arm and forearm. The forearm tolerance was better than the arm.Conclusion:The complication would be greatly attented when the tourniquet is used at high altitude.
