A Comparative Study Between 0.5% Bupivacaine With Clonidine And 0.5% Bupivacaine Alone For Supraclavicular Brachial Plexus Block In Upper Limb Surgeries
Journal Title: International Journal of Medical Science And Advanced Clinical Research (IJMACR) - Year 2019, Vol 2, Issue 1
Abstract
Background:Supraclavicular brachial plexus block provides safe, effective, low cost anaesthesia with excellent post-operative analgesia. The current study was an attempt to compare Bupivacaine 0.5% with Bupivacaine 0.5% plus clonidine 2 μg/kg in supraclavicular brachial plexus block with respect to onset time and duration of sensory blockade, duration of analgesia and side effects. Aim:To evaluate whether additional anaesthetic and analgesic effects could be derived from administration of Clonidine, an α2adrenergic agonist into brachial plexus sheath. Methodology:Each patient was randomly allocated to one of the two groups of 30 patients each. Bupivacaine Group (B): Receives 30 mL Bupivacaine 0.5% and 1 mL of normal saline. Bupivacaine plus Clonidine Group(C): Receives 30 mL Bupivacaine 0.5% and clonidine 2 μg/kg in 1 mL saline. The effect was studied with respect to Onset time and Duration of Sensory and Motor blockade, Duration of Analgesia and Side effects. Results:In our study, we observed that onset of sensory block was earlier in Bupivacaine plus Clonidine group (Group C) having a mean value 7.20±1.95 minutes in comparison with Bupivacaine group (Group B) having a mean value of 17.63±3.25 minutes, which is statistically significant.
