Context: Brachial plexus block is a preferred anesthesia technique for upper limb surgeries below the shoulder joint. Drugs used as adjuvants in block enhance the postoperative analgesia significantly. Aim: We aimed to evaluate the analgesic efficacy, of perineural dexamethasone used as an adjuvant to supraclavicular block as against systemic dexamethasone after supraclavicular block. Time for rescue analgesia was also noted in both groups. Subjects and Methods: In our randomized study, 60 patients belonging to the American Society of Anesthesiologist physical status Classes I and II were randomly allocated in two groups of thirty. Group BD received supraclavicular block with local anesthetic and dexamethasone 0.05 mg/kg as an adjuvant. Group BI received supraclavicular block with local anesthetic and intravenous (IV) dexamethasone 0.05 mg/kg after the block. In both groups, the comparison of postoperative analgesia and time for first rescue analgesic was noted. Statistical Analysis Used: Data analysis was done using SPSS version 20.0. Demographic data and continuous variables were analyzed by independent sample t-test. Categorical data were analyzed by unpaired t-test. Results: Group BD showed significantly prolonged postoperative analgesia as compared to Group BI. Time for rescue analgesic in Group BD was (15.8 ± 2.6) H as compared to Group BI (10.3 ± 1.07) H. Conclusions: Dexamethasone, when used in supraclavicular block significantly, prolongs the duration of analgesia as against IV dexamethasone after supraclavicular block.
