摘　　要：目的:通过对下肢止血带放气速度的控制,减缓松解止血带时引起的血压下降。方法:将在止血带下行下肢手术的患者80例,随机分为实验组和对照组。手术结束后,实验组分三次放气松解气囊止血带,对照组采用传统一次性放气松解气囊止血带。比较在两种方法下,患者血压下降的程度以及伴随症状。结果:两组病人年龄、初始血压、充气时间比较,P>0.05,差异无显著意义。止血带放气后,1min、3min收缩压、舒张压比较,P<0.05,差异有显著性意义。结论:下肢气囊止血带分次放气,能显著减缓血压下降和防止止血带休克。Objective：To slow down the fall of blood pressure by controlling deflation speed of lower limb tourniquet. Methods： Eighty patients who would receive lower limb surgery with tourniquet were randomly divided into experimental group and control group according to their sequences of getting into the operating room. After surgery, the tourniquets were loosed three times in experimental group and once in control group. The change of blood pressure and simultaneous phenomenon were observed both in the two groups. Results：No significant differences were found in age, incipient blood pressure and gasing time between the two groups （P〉0.05）. There were statistical significances at the 1st and 3rd minutes after deflation of tourniquets （P〈0.05）. Conclusion：Fractional deflation of lower limb can effectively slow down the fall of blood pressure and prevent tourniquet induced shock.
