Comparative study between Tramadol and Midazolam as an admixture to bupivacaine inUltrasound guided supraclavicular brachial plexus block.

Background:This is a prospective, randomized, double blind study to evaluate the postoperative analgesia following ultrasound guided supraclavicular brachial plexus block with Tramadol or Midazolam as an admixture to bupivacaine in upper extremity surgery. Patientsand methods:Total 60 patients of ASA I and II undergoing upper extremity surgery under ultrasound guided brachial plexus block with Bupivacaine were randomly divided in to two groups; one group received Tramadol (1mg/kg) and the other group received midazolam (0.05mg/kg) as an admixture to Bupivacaine. The duration of postoperative analgesia was recorded in both groups using pain VAS score. Results: The mean duration of postoperative analgesia in the Midazolam group was 650±47.49 minutes while in the tramadol group it was 508±30.44 minutes. Conclusion: We concluded that midazolamwith local anaesthetic prolongs postoperative analgesiasignificantly than Tramadol (P<0.0001) when used as admixture to local anaesthetic inUltrasound guided brachialplexus block in upper extremity surgery.
