Warm acupuncture on chronic obstructive pulmonary disease with phlegm-turbid obstructing of the lung: a randomized controlled trial

Abstract

To verify the effect of warm acupuncture combined with western medicine in patients with acute exacerbation chronic obstructive pulmonary disease (AECOPD) with phlegm-turbid obstructing of the lung. Ninety patients with AECOPD were randomly divided into a western medicine group, a warm acupuncture group and a sham acupuncture group, 30 cases in each group. Routine treatment according to the Global initiative for chronic obstructive lung disease (GOLD) guidelines was used in the western medicine group. On the basis of the routine treatment, the warm acupuncture was applied at Fenglong (ST 40), Feishu (BL 13), Zusanli (ST 36) and other acupoints in the warm acupuncture group. In the sham acupuncture group, non-acupoints were taken on the basis of conventional treatment, and superficial acupuncture was performed for 1-3 mm, once a day for 2 weeks. Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, cough and sputum assessment questionnaire (CASA), COPD assessment test (CAT), and the change of TCM syndrome score were observed before and after treatment in all groups. After treatment, the FEV1, FVC and FEV1/FVC in each group were higher than those before treatment (P<0.05), there was no significant difference among groups after treatment (P>0.05). The CASA score, CAT score and TCM syndrome score in each group were lower than those before treatment (P<0.05). The change of the scores before and after treatment in the warm acupuncture group was higher than that in the sham acupuncture group and the western medicine group (P<0.05). There was no significant difference between the sham acupuncture group and the western medicine group (P>0.05). Warm acupuncture has a significant effect on the improvement of symptoms in patients with AECOPD with phlegm-turbid obstructing of the lung.
