Abstract :

This prospective, randomized double blind study, compare the effect of Levobupivacaine (L) alone to that of adding Levobupivacaine to Dexmedetomidine (LD) in axillary achial plexus blockade. Sixty patients scheduled to undergo elective forearm and hand surgery were divided in to 2 group of 30 each (group L and group LD). In group L (n = 30) 35ml (175mg) of 0.5% Levobupivacaine + 1ml saline and in group LD (n = 30) 35ml (175mg) of 0.5% Levobupivacaine + 1ml Dexmedetomidine were given. Two groups were compared for motor and sensory onset time, block durations and duration of anaelgesia. There was significant difference in duration between groups. In group LD duration of analgesia was longer then group L (p <0.05). Sensory and motor block onset times were shorter and motor blockade duration were longer in group LD then group L (P< 0.05). Dexmedetomidine added to Levobupivacaine for axillary achial plexus block shortens the onset time of sensory and motor block. It also prolongs the duration of block and duration of postoperative analgesia.
