A COMPARATIVE STUDY OF DEXMEDETOMIDINE AND CLONIDINE AS ADJUNCT TO BUPIVACAINEIN USG GUIDED SUPRACLAVICULAR BRACHIAL PLEXUS BLOCK IN PATIENTS UNDERGOING ELECTIVE UPPER LIMB SURGERIES

ABSTRACT Alpha‑2 agonists are used as adjuvants with Local Anaesthetic (LA) agents to prolong the duration of regional nerve blocks. The prsent study was done to compare clonidine and dexmedetomidine as an adjuvant to bupivacaine in supraclavicular brachial plexus block 70 ASA I and ASA II patients, scheduled for elective upper limb surgeries under ultrasound guided supraclavicular brachial plexus block, were divided into two equal groups. Group-I received clonidine 1 μg/ kg and group-II received dexmedetomidine 1 μg/kg added to bupivacaine 0.5% (20 mL). the age group of the cases ranged between 18-60 years The onset of sensory blockade was faster in group-I (4.01±0. 67 min) than group-II (3.76±0.71 min) but statistically not significant. The onset of motor blockade was faster in group-I (6.1±1.78 min) than group-II (6.9±1.34 min) and difference was statistically significant. Duration of sensory blockade was longer in group-I (616.23±62.05 min) than group-II (574.71±61.14 min) and motor blockade in group-I (615.76±77.12 min) was longer than group-II (552.70±86.19 min) and the differences were statistically significant. The duration of analgesia was longer in group-I (787.79±97.76 min) than group- II (645.00±71.14 min) and the difference was statistically significant.
