Comparative study of Bupivacaine 0.5% versus Bupivacaine plus Dexmedetomidine in supraclavicular brachial block for elective upper limb surgeries.

Abstract

Background : Supraclavicular brachial block is commonly used anaesthetic technique for upper limb surgeries and Bupivacaine is commonly used local anesthestic for block. There is always been search for ideal adjuvants with bupivacaine to fasten the onset of block and prolong the duration of block and analgesia. Recently Dexmedtetomidine is on of the most commonly studied adjuvants to bupivacaine, but result varies significantly in different studies. So we decided to conduct a study to see the effects of adding Dexmedetomidine as an adjuvant to bupivacaine in supraclavicular block.
