Acupoint catgut embedding for asthma in adults: Protocol for a systematic review.

ABSTRACT

BACKGROUND: Asthma exacerbations can do a lot of harm to the patients and consume large amounts of medical resources. Although some studies have evaluated acupuncture for asthma in children, few studies have estimated acupoint catgut embedding therapy. We aim to assess the efficacy and safety of acupoint catgut embedding for asthma in adults. METHODS: The following databases will be searched from inception to December, 2019 Medline, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, the China National Knowledge Infrastructure Database (CNKI), the Chinese Scientific Journal Database (VIP database), and the Wan-fang database. We will also search relevant conference abstracts, and registers of clinical trials. Two reviewers will independently undertake study selection, data extraction, and quality assessment. Data will be synthesized by either the fixed-effects or random-effects model according to a heterogeneity test. The Revman V5.3 software will be used to conduct meta-analysis. RESULTS: The primary outcome was lung function, forced expiratory volume in one second and forced vital capacity (FVC) were the most commonly used parameters to evaluate lung function. The safety assessment includes the incidence of adverse events. CONCLUSION: This systematic review will retrieve clinical randomized controlled trials (RCT) on acupoint catgut embedding for asthma in 7 databases, aiming to describe and update existing evidence on the efficacy and safety of acupoint catgut embedding for asthma in adults.PROSPERO registration number CRD42019148401.
