Effect of acupoint catgut embedding combined with western medicine on patients with stable COPD: Acupoint catgut embedding treating stable COPD meta-analysis

Abstract

Background: Although bronchodilators and glucocorticoids can reduce the symptoms of cough and asthma to a certain extent, the adverse drug reactions and recurrence after recovery still trouble clinicians. Acupoint catgut embedding is effective in preventing and treating acute recurrence and deterioration of COPD, but its clinical efficacy remains controversial. Therefore, this study evaluated the clinical efficacy and safety of acupoint catgut embedding combined with conventional Western medicine for COPD through meta-analysis. Methods: Pubmed, the Cochrane Library, Web of Science, Sinomed, China Knowledge Network, VIP, and Wanfang databases were searched, with a time frame from database creation to November 2022. Meta-analysis was performed with Revman 5.3. Publication bias was assessed by Stata 15.0. Results: Seventeen studies were listed, with a total sample size of 1516 cases. Meta-analysis showed that compared with conventional western medicine, acupoint catgut embedding combined with conventional western medicine could effectively improve the total effective rate of clinical symptoms of stable COPD [RR = 1.21, 95%CI (1.13, 1.29), P
