Effect of Dexmedetomidine as Adjuvant to Ropivacaine for Brachial Plexus Block
March 11, 2023 updated by: Rajiv Yadav, Nepal Medical College and Teaching Hospital
Brachial plexus block is used for upper limb surgery.
Local anesthesia alone for brachial plexus block provides good operative conditions, but have short duration of postoperative analgesia.
Hence, various adjuvants to local anaesthetic agents to prolong the duration of peripheral nerve, analgesia.
However, results are either inconclusive or associated with side effects.
The purpose of this study is to determine whether dexmedetomidine as an adjuvant to ropivacaine in brachial plexus block improve quality of block in terms of duration of post operative analgesia.
