INFLUENCE OF CLONIDINE WITH LOCAL ANESTHESIA ON DURATION OF ANALGESIA IN SUPRACLAVICULAR BRACHIAL PLEXUS BLOCK: A RANDOMIZED CONTROLLED TRIAL.

Introduction: Since the 80's, clonidine has been used as an adjunct to local anesthetics agents in various regional techniques to extend the duration of block. The results of previous studies on the usefulness of clonidine on brachial plexus block have been mixed. To evaluate the efcacy of clonidine, as Material and Methods: an adjunct to the ropovacaine in supraclavicular branchial plexuses on the onset and duration of sensory and motor block. Observations and Results: the onset of sensory and motor bock is the same whether patients receive ropivacaine alone or in combination with clonidine. However duration of both sensory and motor block is signicantly prolonged in Ropivacaine and clonidine group . Clonidine Hcl can s Conclusion: afely be used as an adjunct to local anesthetic agent in supraclavicular brachial plexus block to enhance onset and duration of sensory and motor block and provide better postoperative pain relief in upper limb surgeries.
