Abstract

Ropivacaine, a local anesthetic agent with similar pharmacological profile to that of bupivacaine has lower potential for toxic effect. The aim of our study is to compare the anesthetic characteristics of ropivacaine and bupivacaine when used for supraclavicular brachial plexus blockade in upper limb surgeries. Fifty patients was grouped equally and one group R received 0.5% ropivacaine (100mg) 20ml and another group B received 0.5% bupivacaine (100mg) 20ml. onset & duration of sensory and motor blockade, duration of analgesia and associated complications & side effects were recorded. It was found that there were no significant differences in duration of sensory & motor blockade, in complications or any other side effects in both the groups. But ropivacaine provided rapid onset of action and better quality of surgical anesthesia than bupivacaine when used in supraclavicular brachial plexus blockade.
