不同强度电针抑制带状疱疹后神经痛的量效分析

Comparison of Analgesia Effects of Electric Acupuncture at Different Intensities on Postherpetic Neuralgia

目的:比较不同强度电针抑制带状疱疹后神经痛的临床疗效。方法:将带状疱疹后神经痛患者91例随机分为3组,3组患者均给予电针治疗,但电针刺激强度随机分别设定为1 m A、3 m A、5 m A,共治疗15 d,比较各组患者治疗前、后疼痛视觉模拟评分、情绪评分变化、及综合疗效。结果:在第7次和第15次电针治疗后,3 m A和5 m A电针组疼痛视觉模拟评分、情绪评分、综合疗效明显低于1 m A电针组(P<0.05、P<0.01),而3 m A和5 m A电针组组间疼痛视觉模拟评分、情绪评分、综合疗效比较差异无统计学意义(P>0.05)。结论:电针抑制带状疱疹后神经痛并不是强度越大越好,当电针强度达到3 m A时即可发挥满意疗效。

Objective：To compare the effect of electric acupuncture（EA） at different intensities on patients with postherpetic Neuralgia（PHN）.Methods：We randomly divided 91 PHN patients into three groups,treated them with EA at different intensities for 15 times.The intensities of EA of three groups were set at 1 mA,3 mA,5 mA respectively.The visual analogous scale（VAS）,emotional scale（ES）,and comprehensive curative effects of EA of the three groups were observed before and after treatment.Results：After the treatment by EA for 7 and 15 times,the VAS,ES scores and the comprehensive curative effect of 3 mA and 5 mA group were lower than those of 1 mA group（P 0.05、P 0.01）,but there were no significant differences between the 3 mA and5 mA group（P 0.05）.Conclusion：There is no better effect of intensifying the EA current in treating PHN;Current at 3 mA has the most satisfactory performance.
