The aim was to evaluate the clinical effects of clonidine as an adjuvant to supraclavicular brachial plexus block with 0.5% L-bupivacaine. Permission from Institutional ethical committee was taken before starting the study and informed written consent was taken from all patients. After carefully explaining the procedure to the patients, they were divided randomly into 2 groups by using table of random numbers. Group A (n=30) recieved 30 ml of 0.5 % levobupivacaine with 1 ml normal saline. Group B (n=30) received 30 ml of 0.5 % levobupivacaine with 0.3 ml clonidine (50 µg) diluted with normal saline to make up the solution 1 ml. Drugs were prepared by anesthetist who was not involved in the proceedings of the study.
