Résumé
Supraclavicular brachial plexus block is one of the most commonly employed regional anesthesia technique & is often described as “Spinal anesthesia of Upper limb”. Bupivacaine is one of the commonly used local anesthetic used for plexus anesthesia as it has long duration of action, however many additives have been tried in various studies in the search to decrease the latency of its onset of neural blockade as well as to increase its duration of analgesia, thereby improving the efficacy of peripheral neural blocks. We therefore studied the effect of clonidine 150 micrograms when added as an adjunct to bupivacaine for supraclavicular brachial plexus block in comparison with Bupivacaine combined with Epinephrine and Bupivacaine alone, in a rural tertiary care medical institute. We found that addition of clonidine provides rapid onset of anesthesia along with prolonged sensory, motor blockade and prolonged duration of analgesia without any significant side effects as compared to 2.025% bupivacaine with epinephrine or 0.25% Bupivacaine alone.
