Comparative Evaluation of the Effects of Fentanyl and Dexmedetomidine as an Adjuvants in Supraclavicular Brachial Plexus Block Achieved with Ropivacaine
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 2
Abstract
Introduction: Supraclavicular brachial plexus block provides complete and reliable anaesthesia for upper limb surgeries. Ropivacaine, is a potent blocker of C and Aδ fibres, rendering good sensory effect but less motor blockade. We evaluated the anaesthetic quality and duration of analgesia with the addition of either fentanyl or dexmedetomidine to ropivacaine 0.5% for brachial plexus block. Material and methods: In a double blind randomized prospective clinical trial, 120 patients were randomly allocated to either receive 30 ml ropivacaine 0.5% (Group 1), 30 ml ropivacaine 0.5% with fentanyl (Group 2) or 30 ml ropivacaine 0.5% with Dexmedetomidine (Group 3) in brachial plexus. Results: Compared to the use of ropivacaine 0.5%, 30 ml alone for brachial plexus block, the addition of fentanyl or dexmedetomidine to ropivacaine enhanced onset of block and also increased duration of anaesthesia with prolongation of post-operative analgesia. Conclusion: Blockade characteristics improved better with addition of dexmedetomodine then fentanyl without increasing incidence of unwanted side effects.
