Abstract
BACKGROUND: Pneumonia is a common respiratory disease. In severe cases, it can induce cardiovascular disease and even life-threatening. In particular, pneumonia caused by the new coronavirus (SARS-CoV-2) that broke out at the end of 2019 has seriously affected the health of people in all countries. In recent years, it has been treated with the combination of traditional Chinese medicine (TCM) (such as Reduning injection) and Western medicine, and its mortality has decreased significantly. But their efficacy has not been scientifically and systematically assessed. Accordingly, it is essential to provide a systematized review program to estimate the efficacy and safety of Reduning injection combined with Western medicine to treat pneumonia. METHODS: The following databases are retrieved from start to September 2020: Pubmed, Cochrane Library, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI), Wanfang database, the Chongqing VIP Chinese Science and Technology Periodical Database (VIP) databases, Chinese Biomedical Literature Database (CBM), and other databases, which are absorbed into clinical RCTs of pneumonia using western medicine alone or plus Reduning injections. The selection of studies, data extraction, and assessment of risk of bias will be performed independently by 2 reviewers. At the same time, Review Manager V.5.3.5 (Rev Man V.5.3.5) was used for bias risk assessment and data synthesis. RESULTS: The efficacy and safety of Reduning injection combined with western medicine in the treatment of pneumonia were evaluated in terms of overall effective rate, the patient's antipyretic time, antitussive time, rales disappearing time, X-ray recovery time, and the incidence of adverse reactions. CONCLUSIONS: This study provides reliable evidence-based support for the clinical application of Reduning injection combined with western medicine for pneumonia. ETHICS AND DISSEMINATION: Ethical approval is not required in this secondary research evidence, and we will publish the results of this study in a journal or relevant conferences.
