This study aimed to compare the efficacy of ultrasound-guided infraclavicular block using Bupivacaine alone versus Bupivacaine combined with Dexmedetomidine for postoperative analgesia in upper limb surgeries. A total of 60 patients were randomly divided into two groups: Group A received 0.5% Bupivacaine, and Group B received 0.5% Bupivacaine with 0.75 μg/kg Dexmedetomidine. The primary outcomes measured were the onset and duration of sensory and motor block, as well as the duration of analgesia. Results showed that Group B had a significantly faster onset and longer duration of sensory and motor block, as well as prolonged analgesia compared to Group A. No complications were observed in either group. These findings suggest that the addition of Dexmedetomidine improves the effectiveness of infraclavicular blocks for postoperative analgesia.
