Efficacy and safety of Chinese herbal medicine Wuwei Xiaodu Drink for wound infection: A protocol for systematic review and meta-analysis

Wound infection (WI) is a disease in which pathogenic bacteria invade and multiply in a wound after trauma or surgery, causing a systemic inflammatory response. WI triggers an immune response in the body, resulting in inflammation and tissue damage, as well as slowing down the healing process. The traditional Chinese medicine prescription of Wuwei Xiaodu Drink (WWXDD) has been widely used in clinical practice with good results. However, there is no high-level evidence to support this result. The purpose of this study was to evaluate the efficacy and safety of WWXDD in the treatment of WI. METHODS: We will search articles in 7 electronic databases including Chinese National Knowledge Infrastructure (CNKI), Wanfang Data (WF), Chinese Scientific Journals Database (VIP), Chinese databases SinoMed (CBM), PubMed, Embase, and Cochrane Library databases. All the publications, with no time restrictions, will be searched without any restriction on language and status, the time from the establishment of the database to October 2022. Two reviewers will independently assess the quality of the selected studies, NoteExpress and Excel software will be used to extract data, and the content will be stored in an electronic chart. Different researchers will separately screen the titles and abstracts of records acquired potential eligibility which comes from the electronic databases. Full-text screening and data extraction will be conducted afterward independently. Statistical analysis will be conducted using RevMan 5.4 software (Cochrane Collaboration). RESULTS: What this study will do is evaluate the efficacy and safety of WWXDD in the treatment of WI in order to provide high quality, evidence-based clinical recommendations. CONCLUSION: This research provides a trusted clinical foundation for the treatment of WI with WWXDD.
