Two researchers then independently screened articles, extracted data, and evaluated the quality of selected literatures. All data was processed by Stata 14.0 and WinBUGS 1.4.3.software.Results:The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.Conclusion:Our study is expected to provide high-quality evidence-based medicine advice for the effects of different doses of dexamethasone as local anesthetic adjuvant on brachial plexus block.Ethics and dissemination:Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms.OSF REGISTRATION NUMBER:DOI 10.17605/OSF.IO/PZ5WR.
