Abstract:Introduction: Supraclavicular brachial plexus block provides safe, effective, low cost anaesthesia with good postoperative analgesia. This study was conducted to compare the postoperative analgesic efficacy and safety of dexmedetomidine for brachial plexus blockade along with bupivacaine. Methodology: This prospective double blind study was conducted on 70 patients of age 18 to 60 years posted for various upper limb surgeries and randomly allocated into two equal groups of 35 each. Control group-C received injection bupivacaine (0.25%) 38 milliliter plus 2 milliliter normal saline, dexmedetomidine group-D received injection bupivacaine (0.25%) 38 milliliter plus dexmedetomidine 30 microgram (2 milliliter). Assessment of motor and sensory blockade, pulse, systolic blood pressure, respiration and side effects were noted every 5 minutes for first 30 minute and every 10 minute till end of surgery. Duration of analgesia and incidence of various complications following the procedure were observed. Results: It was observed that in control group onset of motor and sensory blockade was faster. Where as, dexmedetomidine group have better hemodynamic stability and greater postoperative analgesia. Only two cases of bradycardia and two cases of hypotension were noticed in dexmedetomidine group-D.
