[ acupuncture technique in for moderate-to-severe obstructive sleep apnea-hypopnea syndrome: a randomized controlled trial].

OBJECTIVE

To observe the clinical efficacy of (directing flowing) acupuncture technique in () for moderate-to-severe obstructive sleep apnea-hypopnea syndrome (OSAHS).

METHODS

Sixty patients with moderate-to-severe OSAHS were randomly divided into a Daoqi acupuncture group (30 cases) and a conventional acupuncture group (30 cases, 1 case dropped out). In the Daoqi acupuncture group, acupuncture technique in was applied at Shanglianquan (Extra), Fengfu (GV16), and bilateral Lieque (LU7), Zhaohai (KI6); in the conventional acupuncture group, conventional acupuncture was applied at Shanglianquan (Extra), Fengfu (GV16), Yamen (GV15), and bilateral Lieque (LU7), Zhaohai (KI6), Zusanli (ST36), Fenglong (ST40). The treatment was adopted once every other day, 3 times a week, 4 weeks as one course and 3 courses were required totally in both groups. Before and after treatment, the polysomnography (PSG) indexes [apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), longest apnea duration, lowest nocturnal SaO (LSaO)], and scores of Epworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQI), World Health Organization quality of life-BREF (WHOQOL-BREF) were observed, and the clinical efficacy was evaluated after treatment in the two groups.

RESULTS

After treatment, the AHI, HI, AI and longest apnea duration were reduced compared with those before treatment in the two groups (<0.01), the LSaO was increased in the Daoqi acupuncture group (<0.01); in the Daoqi acupuncture group, the AHI, HI, AI and longest apnea duration were lower than those in the conventional acupuncture group (<0.05), and the LSaO was higher than that in the conventional acupuncture group (<0.05). After treatment, the ESS and PSQI scores were decreased compared with those before treatment (<0.01), while the WHOQOL-BREF scores were increased compared with those before treatment (<0.01) in the two groups; in the Daoqi acupuncture group, the ESS and PSQI scores were lower than those in the conventional acupuncture group (<0.05, <0.01), and the WHOQOL-BREF score was higher than that in the conventional acupuncture group (<0.05). The total effective rate was 93.3% (28/30) in the Daoqi acupuncture group, which was higher than 82.8% (24/29) in the conventional acupuncture group (<0.01).

CONCLUSION

acupuncture technique in can effectively treat moderate-to-severe OSAHS patients, improve the clinical symptoms and quality of life, and has the advantages i.e. simpler acupoints selection and gentler stimulation.
