头穴透刺法治疗失眠症的随机对照研究

背景：失眠已成为威胁公众身体健康的突出问题，针灸在治疗失眠方面具有疗效高和副作用小的优势。 目的：观察头穴透刺法治疗失眠症的临床疗效。 设计、场所、对象和干预措施：将符合纳入标准、源于解放军总医院针灸科门诊的70例失眠患者随机分为头穴透刺组和常规针刺组，其中脱落4例，最终头穴透刺组纳入32例，常规针刺组纳入34例。头穴透刺组给予头穴透刺法，而常规针刺组则给予一般针刺疗法。两组患者均治疗4周。 主要结局指标：比较两组临床疗效、治疗前后匹兹堡睡眠质量指数量表积分和睡眠结构各成分的变化。 结果：头穴透刺组总有效率为90.6%，优于常规针刺组的73.5%（P＜0.05）。头穴透刺法对睡眠质量、睡眠时间及睡眠效率的改善均优于常规针刺法（P＜0.05，P＜0.01）。头穴透刺法能明显增加睡眠总时间和深睡期时间，与常规针刺组相比，差异有统计学意义（P＜0.01）。 结论：头穴透刺法治疗失眠症的临床疗效优于常规针刺法，主要体现在改善睡眠质量、睡眠时间及睡眠效率等方面。

Results： The total response rate of 90.6% in the scalp penetration acupuncture group was higher than 73.5% in the routine acupuncture group （P〈0.05）, and the improvements of PSQI cumulative scores in sleep quality, sleep time and sleep efficiency in the scalp penetration acupuncture group were superior to those in the routine acupuncture group （P〈0.05, P〈0.01）. The total sleep time and deep sleep time of sleep architecture in the scalp penetration acupuncture group significantly increased as compared with those in the routine acupuncture group （P〈0.01）.
