摘　　要：目的探讨温度骤降对人体血压的影响,以及耳穴按摩对血压波动的保护作用。方法 2016年12月—2017年2月,选取石河子大学医学院汉族学生100名为研究对象。采用随机数字表法,将研究对象分为无干预组、干预组,各50名,测量两组基础平均动脉压(MAP)。无干预组从有供暖的室内平稳来到温差20、25、30℃的室外,测量即时、5 min后血压。干预组进行耳穴按摩5 min后,平稳来到温差20℃的室外,测量即时、5 min后血压。结果无干预组随着暴露寒冷环境温差的增大,即时、5 min后MAP逐渐升高(P<0.05)。无干预组基础MAP为(85±3)mm Hg,暴露在温差20℃的寒冷环境即时MAP高于基础MAP(t_(配对)=3.14,P<0.05);5 min后MAP与基础MAP比较,差异无统计学意义(t_(配对)=0.97,P>0.05)。暴露在温差25、30℃的寒冷环境即时以及5 min后MAP均高于基础MAP(t_(配对)=7.07、2.21,t_(配对)=12.41、13.76,P<0.05)。干预组耳穴按摩后室温下MAP为(77±4)mm Hg,低于基础MAP的(85±3)mm Hg(t_(配对)=4.23,P<0.05)。暴露在温差20℃的寒冷环境中,即时MAP为(83±1)mm Hg,低于无干预组的(86±2)mm Hg(t=2.20,P<0.05),5 min后MAP为(84±1)mm Hg,高于即时MAP(t_(配对)=-13.01,P<0.05)。结论气温骤降可使血压升高,而耳穴按摩可抑制气温骤降引起的血压波动。Objective To investigate the blood pressure response to sudden drops in temperature,and to explore the effect of ear acupoint massage on reducing this kind of response.Methods One hundred Han college students were enrolled from School of Medicine,Shihezi University during December 2016 to February 2017 and equally divided into intervention group and non-intervention group based on the random number table（50 cases for each group）.After the measurement of MAP in a heated room with a temperature of 15 ℃,students in the intervention group first received 5-minute ear acupoint massage,measured MAP again,after that,they walked calmly to the outdoor environment with a temperature of-5 ℃,then MAP was measured immediately and at 5 minutes later;those in the non-intervention group walked calmly to three types of cold outdoor environments（-5 ℃,-10℃,-15 ℃）,respectively,and MAP was measured immediately and at 5 minutes later respectively under these three conditions.Results For those in the non-intervention group,both the MAP measured immediately and 5 minutes later after they exposed to the three cold environments increased gradually with the decrease of temperature（P0.05）.To be specific,the MAP measured immediately after they exposed to the environment with a temperature of-5 ℃ was significantly higher than the baseline MAP [（85±3） mm Hg]（t_（paired）=3.14,P0.05）,but it was similar to the baseline MAP 5 minutes later（t_（paired）=0.97,P0.05）.However,when they exposed to the environment with a temperature of-10 ℃,both the MAP measured immediately and 5 minutes later were all significantly higher than the baseline MAP（t_（paired）=7.07,2.21,P0.05）.The same status occurred when they exposed to the environment with a temperature of-15℃（t_（paired）=12.41,13.76,P0.05）.For those in the intervention group,the MAP measured following the ear acupoint massage was much lower than the baseline MAP[（77±4） mm Hg vs.（85±3）mm Hg]（t_（paired）=4.23,P0.05）.In the environ
