不同材质针灸针温针灸的温度特性研究

目的:研究不同材质针灸针温针灸在人体穴位的温度特性及初步调查受试者对其的响应。方法:纳入10名健康受试者,通过数字测温仪观察不锈钢针、金针、银针温针灸过程中针体与皮肤接触处针体的温度时间曲线,记录人体对温针灸的热痛阈和耐热痛阈。通过问卷调查了解健康受试者在不同温针灸过程中的舒适感、热感、不良反应以及对其的接受度。结果:大灸量(1.5g艾)的银针温针灸温热刺激最强、持续时间最长,其次依次为小灸量(1.2g艾)的银针、大灸量(1.5g艾)金针、大灸量(1.5g艾)不锈钢针。受试者对不锈钢针和金针温针灸都可忍受,30%的受试者觉得两种银针温针灸太烫而不能忍受;不锈钢针和金针温针灸后未见不良反应,而两种银针温针灸后分别有40%和90%的受试者出现表面轻度灼伤;受试者对温热刺激相对较小的不锈钢针、金针和小灸量银针灸表示都能接受,而对于大灸量银针灸,接受率为70%;所有受试者都表示愿意接受温针灸治疗后的表面轻度灼伤或起泡反应。结论:小灸量银针灸可产生足量的温热刺激而不引起明显的不良反应和不适感。但在临床施治前,仍需告知患者可能出现的不良反应,并征求患者同意后再行施灸。

Temperature Characteristic of Moxibustion with Warming Needles Made of Different Materials

Objective: To observe the temperature characteristics of moxibustion with warming needle of different materials at acupoint and the response of the subjects.Methods: 10 healthy volunteers were recruited.Three kinds of needle including stainless steel needle,gold needle and silver needle with two different weights of moxa(1.2g and 1.5g) were used.The temperature at the acupoint where needle penetrate the skin was recorded with a digital thermometer.During the experiment,the heat pain threshold and the heat p...
