针刺三阴交等对原发性痛经患者止痛作用时效规律的初步观察

Preliminary Observation on Analgesic Effect's Time-effectiveness Rule of Acupuncture Sanyinjiao to Primary Dysmenorrhea

目的:探讨基于留针30 min条件下,针刺三阴交、地机、次、十七椎对原发性痛经患者止痛作用的时效规律。方法:针刺三阴交、地机、次、十七椎,留针30 min,分别记录针刺前即时、留针5 min、10 min、20 min、30 min及起针后30 min、60 min、120 min的VAS读值,然后进行统计分析。结果:留针30min条件下,针刺止痛作用持续加强,直至起针;起针40 min后,针刺止痛作用衰减为接近峰值的一半。结论:针刺三阴交等多个穴位时,留针30 min的止痛作用优于留针短于30 min的止痛效果。针刺三阴交等多个穴位时,留针30 min条件下的半衰期较短,对于痛经持续时间在1天左右或更长的患者,针刺频次以每天针刺2次为宜。

Objective:This paper summarizes time-effectiveness rule of analgesic effect to primary dysmenorrhea of acupuncture sanyinjiao,diji,ciliao and shiqizhui when retain needles for 30min.Methods: Acupuncture those points and retain needles for 30min,record the VAS read values of different time,then carries on statistical analysis.Results: The analgesic effect of acupuncture continued to strengthen in 30min,and weaken for nearly half of the peak after withdrawed needles 40min.Conclusion: the analgesic effect to primary dysmenorrhea of retaining needles for 30min is superior to retaining needles less than 30min on acupuncture those points.The half-life of retain needles for 30min is short,so it is appropriate to acupuncture twice a day for those who dysmenorrhea duration of about one day or more.
