针刺单穴 多穴治疗原发性痛经止痛作用时效规律的初步比较

Comparison on the Analgesic Action of the Time-effect Regularity in Patients with Primary Dysmenorrhea Between Acupuncture of Single Point and Acupuncture of Several Points

方法:将符合纳入标准的20例原发性痛经患者随机分为针刺十七椎单穴组、针刺十七椎等多穴组,均留针30min,分别记录针刺前即时、进针5、10、20、30min及起针后30、60、120min的VAS读值,然后进行统计分析。结果:针刺后,两组的止痛作用迅速产生,留针30min内,两组患者的止痛作用均持续加强,直至起针;进针20min时多个穴位组的即时止痛作用明显优于针刺单穴组(P<0.05),这一差别在起针后不久又逐步缩小。结论:单刺十七椎、针刺十七椎等多个穴位对原发性痛经患者均有明显的即时止痛作用,且两组针刺作用的时效规律具有相同的变化趋势,但针刺多个穴位组的即时止痛作用在多个时点明显优于针刺十七椎单穴组。

Methods：20 patients met the inclusion criteria of primary dysmenorrhea were randomly divided into the acupuncture group of 17 vertebrae single point and the other group of some points including 17 vertebrae.The both groups have needles remaining for 30minutes,and we recorded respectively the VAS on the point of before acupuncture,needle remaining for 5 mins,10 mins,20 mins,30 mins,and after acupuncture 30 mins,60 mins,120 mins,then statistically analysised.Results：The analgesic effect quickly appears after acupuncture and continues to enhance within 30 min in the two groups until the end of acupuncture.Remaining for 20 mins,some points group with 17 vertebrae significantly is superior to the single point group（P〈0.05）.This difference after acupuncture gradually narrows.Conclusion：The both groups have obvious immediate analgesic effect to patients with primary dysmenorrhea,and the role of the two groups of acupuncture aging law have the same trend,but more than one point group in a number of time points are better than a single point group.
