Comparison between Perineural and Intravenous Dexamethasone on Duration of Analgesia in Supraclavicular Brachial Plexus Block - An Observational Study

When compared to the intravenous route, the perineural route of dexamethasone was shown to be beneficial in extending the duration of anesthesia for up to 24 h, which resulted in prolonged pain-free and a reduced need for rescue analgesia. Furthermore, enhanced recovery was noted in patients when dexamethasone was given via the perineural route due to the extended duration of pain relief.
