Background and Aims: Clonidine has been used as an adjuvant to local anesthetic to extend the duration of block. The present study was aimed to compare the onset and duration of sensory and motor blockade of 0.75% ropivacaine alone or in combination with clonidine during ultrasound guided supraclavicular brachial plexus block for upper extremity surgeries under tourniquet. Materials and Methods: Sixty four adult American Society of Anesthesiologist grade 1 and 2 patients, scheduled for upper extremity surgeries were randomized to receive either 19.8 mL of 0.75% ropivacaine with 0.2 mL of normal saline (Group R) or 0.2 mL (30 μg) of clonidine (Group RC) in supraclavicular block. Onset and duration of sensory and motor blockade was compared. The hemodynamic variability, sedation, respiratory adequacy and any other adverse effects were also recorded. Result: Ultrasound helped to visualize the nerves, needle and spread of local anesthetic at the brachial plexus block site. There was no statistically significant difference in the onset of sensory and motor blockade between the groups. Surgical anesthesia was achieved at the mean time of 20 min in all patients. Prolonged post-operative analgesia (mean duration 956 min) was observed in RC group as compared with R group (736 min). No complication of technique or adverse effect of ropivacaine and clonidine was reported. Conclusion: Clonidine as an adjuvant to ropivacaine for ultrasound guided supraclavicular brachial plexus enhanced duration of post-operative analgesia. There was no incidence of vessel puncture or pneumothorax.
