Comparison between Dexamethasone and Clonidine as an adjuvant to 0.5% Levobupivacaine in Supraclavicular brachial plexus block

Background: Regional anesthesia avoids airway instrumentation, preserves conscious level and provide rapid recovery with significant postoperative analgesia. There has always been a search for adjuvants to the regional nerve block drugs that prolong duration of analgesia but lesser adverse effects. The ideal additive still continues, therefore in this study, we investigated effects addition dexamethasone versus clonidine levobupivacaine supraclavicular brachial plexus block. primary outcome study was onset sensory block, motor secondary Aims Objectives: aim compare effect on anesthesia, when used as an adjuvant 7. Materials Methods: In prospective, double-blind, randomized controlled trial, 60 patients American Society Anaesthesiologists physical status I/II scheduled undergo upper limb surgeries below shoulder were enrolled. randomly divided into two groups: Group I (n=30): 20 mL 0.5% isobaric 2 dexamethasone. II 30 mcg (diluted normal saline, making volume mL). Results: Clonidine added early less blockade compared Conclusion: Dexamethasone should be preferred whenever longer post-operative is required.
