We experimented effect of clonidine on characteristics of ropivacaine-induced supraclavicular brachial plexus block.
Sixty adult patients were randomly recruited to two groups of 30 each: Group R: 30 ml 0.5% ropivacaine + 1 ml normal
saline. Group RC: 30 ml 0.5% ropivacaine + 150 mcg clonidine. The onset of sensorimotor block was earlier in Group RC (3.67± 0.75 min for
sensory block and 7.67 ± 1.12 min for motor block) than in Group R (5.5± 0.94 min for sensory block and 12.27 ± 1.84min for motor block). The
duration of sensory and motor block and analgesia were prolonged by clonidine (P < 0.001). Addition of clonidine in supraclavicular brachial
plexus block with ropivaicane decrease the onset and increase the duration of sensory and motor block with prolonged duration of analgesia.
