不同时间电针治疗失眠疗效评价

Comparison of Therapeutic Effects of Electroacupuncture Treatment of Insomnia at Different Time

目的:比较晚上和上午电针治疗失眠症的疗效差异。方法:将60例失眠患者随机分为晚上电针组和上午电针组,每组30例,分别于晚上(8～9点)和上午(8～11点)接受电针治疗。选取百会、神庭、头维(双侧)、上印堂、神门(双侧)、三阴交(双侧)穴,头部穴位刺入骨膜下15mm,百会和神庭加电针(频率2～100Hz,电流1～3mA),留针20min,每日1次,5d为1疗程,治疗2个疗程。观察治疗前后匹兹堡睡眠质量指数(PSQI)评分、睡眠率及催眠药物使用的变化情况。结果:晚上电针组和上午电针组都可降低PSQI评分,提高睡眠率,晚上电针组优于上午电针组,组间比较差异具有显著性意义(P<0.05)。而晚上电针组第1天能明显提高患者睡眠率(P<0.01),表现出即时疗效。另外,电针治疗后晚上电针组的催眠药物使用明显减少(P<0.01),上午电针组则无明显改变(P>0.05)。结论:晚上电针可明显降低失眠患者PSQI评分,提高睡眠率,减少催眠药物使用频次,并且具有即时效应,优于上午治疗。

Objective To compare the therapeutic effects of evening-electroacupuncture （EA） and morning-EA for insomnia. Methods Sixty cases of simple insomnia patients were randomly divided into evening-EA group and morning-EA group, with 30 cases in each. EA （2/100 Hz, 1 - 3 mA） was applied to E, aihui （GV 20）, Shenting （GV 24）, Touwei （ST 8）, Shenmen （HT 7）, Sanyinjiao （SP 6）, etc, in the evening （8： 00 - 9： 00 pm） and in the morning （8： 00-- 11 ： 00 am） respectively in two groups, once daily for 10 times, Changes of mean global Pittsburgh Sleep Quality Index （PSQI）, sleep rate, frequency of hypnotic-taking, etc were observed before and after the treatment. Results In comparison with pre-treatment, mean PSQI scores in evening-EA and morning-EA groups, and hypnotic-taking frequency in evening-EA group decreased evidently during two weeks after the treatment, and sleep rates of two groups increased significantly from the 1st day on after the treatment in evening-EA group and from the 1st week on in morning-EA group （P〈 0.01 ）, Comparison between two groups showed that the mean PSQI scores at the 1st and 2nd week in evening-EA group were significantly lower, and the sleep rate in evening-EA group on the 2nd week after the treatment was considerably higher than that in morning-EA group （ P〈0, 05）, Conclusion Evening-EA can significantly lower insomnia patients＇ PSQI score, raise sleep rate, and reduce the hypnotic-taking frequency, Evening-EA is superior to morning-EA in the treatment of insomnia,
