摘要
目的:观察不同力度按压心俞对局部血流速度和温度的影响。方法:招募20名健康志愿者,分别用极轻、轻度、中度、重度、极重5级力度分别按压志愿者左侧心俞,观察其中12名志愿者按压后局部动脉收缩期峰值血流速度和其余8名志愿者的局部温度变化。结果:5级力度(由轻到重)按压心俞后血流速度增长值分别是[-4.68 (-6.92,-1.56)] cm/s,[2.16(1.30,3.35)] cm/s,[1.86 (0.78,4.26)] cm/s,[4.94 (2.31,7.63)] cm/s,[1.56 (-1.95,2.47)] cm/s,对按压前后各组血流速度差值进行统计与多重比较:轻度、中度和重度按压后血流速度与按压前比较均增高,差异均有统计学意义(P<0.05);且重度效应明显于轻度和中度,差异均有统计学意义(P<0.05);按压后即刻温度增长值分别是(1.88±0.64)℃、(2.05±0.68)℃,(2.25±0.59)℃,(2.35±0.61)℃和(2.32±0.69)℃,多重比较结果:极重和重度按压效应优于其他,差异均有统计学意义(P<0.05)。结论:在一定范围内,随着按压力量的增加,心俞穴局部温度和血流速度都有增加的趋势。按压力量取重度时,心俞穴局部血流速度与局部温度最大。
Objective:To observe the effect of pressing Xinshu point(BL15) with different strength on local blood flow velocity and temperature. Methods:Twenty healthy volunteers were recruited and pressed the left Xinshu point with five levels of force:extremely mild, mild, moderate, heavy and extremely heavy. The changes of peak systolic blood flow velocity of 12 volunteers and the local temperature of the remaining eight volunteers were observed. Results:The increase of blood flow velocity after five levels of force from lightly to heavily was [-4.68(-6.92,-1.56)]cm/s,[2.16(1.30,3.35)]cm/s,[1.86(0.78, 4.26)]cm/s, [4.94(2.31, 7.63)]cm/s, [1.56(-1.95, 2.47)]cm/s, respectively;the differences of blood flow velocity before and after pressing were statistically analyzed and compared:The difference of blood flow velocity between the pressure before and after was mild, moderate and heavy pressed was higher, and the difference were statistically significant(P<0.05). And the heavy effect was superior to mild and moderate,the difference were statistically significant(P<0.05). The increase of temperature after pressing immediately was(1.88±0.64)℃,(2.05±0.68)℃,(2.25±0.59)℃,(2.35±0.61)℃ and(2.32 ± 0.69)℃, respectively;the differences of temperature were statistically analyzed and compared:extremely heavy and heavy were superior to the others,the difference were statistically significant(P<0.05). Conclusion:In a certain range,with the increase of pressing force,the local temperature and blood flow velocity of Xinshu point have an increasing trend. When the pressing force is heavy, the blood flow velocity and local temperature of Xinshu point are the largest.
