Abstract :

Objectives: To compare bupivacaine(0.5%) and levobupivacaine(0.5%) in usg guided supraclavicular achial plexus block with respect to onset and duration of sensory and motor block, duration of analgesia, and the presence of adverse events.

Methods: The present study was conducted in random 60 patients of either sex, aged between 18yrs and 60 yrs undergoing hand, forearm and upper arm surgery having ASA grade 1 and 2. The patients were randomly allotted into two groups each having 30 patients. Group L – inj. Levobupivacaine 0.5% 20 ml Group B– inj. Bupivacaine 0.5% 20 ml and the effects were assessed.

Results: There was significant difference in duration of motor block (<0.05), and analgesia (<0.05) in both the groups. The average duration of motor block was 490.67±75.75 minutes in L Bupivacaine group whereas it was 617.97±90.86 minutes in Bupivacaine group which was significant statistically. The average duration of analgesia was 677.50±68.19 minutes in L bupivacaine group as compared to 633.47±94.26 minutes in Bupivacaine group which was also statistically significant. None of the groups showed adverse effects due to drugs(cardiovascular and CNS toxicity) or mechanical or other effects of technique, such as needle trauma.

Conclusion: Bupivacaine(0.5%) provides a better motor blockade whereas levobupivacaine(0.5%) has added advantage of prolonged postoperative analgesia for supraclavicular block added with accuracy of ultrasound imaging.
