A comparative study of effects of 0.5% isobaric levobupivacaine with 0.5% bupivacaine in interscalene brachial plexus block for upper limb surgeries

Isobaric levobupivacaine is a long acting amide type of local anaesthetic that S-enantiomer racemic bupivacaine with clinical profile resembling bupivacaine. It has been stated its faster protein binding rate reflects decreased degree toxicity and studies done have supported it lesser cardiovascular central nervous system than Sixty patients aged between 18yrs 60yrs physical status ASA grade 1 2 undergoing elective upper limb surgeries were included in the study after ethical clearance from college committee. The mean duration motor block Bupivacaine group was 485.33±59.75 min 467.67±56.85 Levobupivacaine group. There no significant statistical difference seen two groups regards to (p=0.170).
