Ropivacaine is a new amino amide local anaesthetic with less cardiotoxicity when compared to Bupivacaine. The aim of our study is to compare ropivacaine 0.75% with bupivacaine 0.5% when both of them are combined with xylocaine 2% in upper limb surgeries under supraclavicular block. Material and Method: In this prospective double blind study, sixty patients of ASA- I and II scheduled for upper limb orthopaedic surgeries were randomly divided into two groups. Group R received Ropivacaine 0.75% 20 ml plus Xylocaine 2% 10 ml while Group B received Bupivacaine 0.5% 20 ml plus Xylocaine 2% 10 ml via supraclavicular route. Results: Group Bupivacaine showed prolonged duration of sensory and motor block and prolonged duration of analgesia compared to Group Ropivacaine but the difference was statistically insignificant. (p>0.05) Conclusion: Ropivacaine 0.75% and bupivacaine 0.5% showed similar onset and duration for sensory and motor block when used for supraclavicular brachial plexus block along with xylocaine. They also provide almost equal duration of analgesia. Because Ropivacaine has a potentially proven safety profile compared to Bupivacaine, it may offer an advantage.

They achieve ideal operating conditions by producing complete muscular relaxation maintaining stable intraoperative hemodyanamics and the associated sympathetic block. Regional Anesthesia has more to offer in orthopedic surgery than in any other surgical specialty, either alone or as part of an anesthetic sequence. With Regional Anesthesia there are 1 better preservation of mental functions in elderly; intact pharyngeal and laryngeal reflexes, thus decreasing the risk of aspiration; it ensures a decreased stress response in compromised patients and avoidance of difficult intubation 2 ; it also decreases post operative complications associated with intubation; and it provides better postoperative pain relief without undue sedation facilitating early mobilization and discharge. Bupivacaine has been in clinical use for more than 30 years. It is widely used foranaesthesia but it is associated with a number of side effects, including motor weakness, cardiovascular and central nervous system toxicity 4 . This has resulted in the continuing search for new and safer local anaesthetic Agents. Ropivacaine has several properties which may be useful in practice, namely thepotential to produce differential neural blockade with less motor block andreduced cardiovascular and neurological toxicity 3 . The present study is to compare the effect of ropivacaine 0.75% 20 ml plus xylocaine 2% 10 ml versus bupivacaine 0.5% 20 ml plus xylocaine 2% 10 ml in upper limb surgeries under supraclavicular block. AIMS AND OBJECTIVES To compare the effect of Ropivacaine 0.75% 20 ml plus lignocaine 2% 10 ml versus bupivacaine 0.5% 20 ml plus lignocaine 2% 10 ml in upper limb surgeries under supraclavicular block including onset and Duration of sensory block; onset and duration of motor block; duration of post operative analgesia; hemodynamic changes; and any side effects or complications.
