Abstract :
Introduction: Peripheral nerve blocks are becoming popular day by day because of their relative safety and precision. The present study aimed to compare the effectiveness of clonidine versus midazolam as an adjuvant to local anesthetics in ultrasound guided supraclavicular brachial plexus block.
Materials and Methods: A prospective randomised control study where total of 100 adult patients of either sex, aged between 18 -60 years of ASA physical status 1 and 2 undergoing elective upper limb surgeries were divided equally into two groups by computer generated random number method. Group C: where inj. clonidine -150mcg was used as an adjuvant in addition to inj xylocain plain 2% -10ml and inj bupivacaine plain 0.5%- 20ml in ultrasound guided supraclavicular brachial plexus block. Group M: where inj. Midazolam (preservative free)- 5mg was used as an adjuvant in addition to local anesthetics as mentioned above for group C. In both groups onset of sensory block, onset of motor block, duration of sensory block, duration of motor block, sedation measured by sedation scale(culebras), post operative analgesia using VAS at 0 min, 30min, 1hr, 2hr, 3hr, 6hr and 12hr were recorded.
Results: Post operative analgesia was significantly prolonged in Group C (VAS
