A prospective, randomised, double blind study comparing dexamethasone and dexmedetomidine as adjuvants to 0.2% ropivacaine for post-operative analgesia in ultrasound guided brachial plexus block

The Adjuvants added to local anaesthetic increases the duration of post-operative analgesia and decreases analgesic requirement in period. study was conducted with intent comparing effect Dexamethasone Dexmedetomidine ultrasound guided Brachial Plexus Block. A prospective, randomised, double blind compare as adjuvant 0.2% Ropivacaine Ultrasound Guided 60 patients belonging ASA I II scheduled for upper limb surgeries were included after taking informed consent. Group received 20ml 8mg Dexamethasone. B 50 µg Dexmedetomidine. Our primary objective time first request both groups. Secondary sensory motor block period overall 24 hours mean group 635.47 ± 26.29 minutes 827.47 54.62 minutes. Similarly, 681.5 27.19 877.17 52.85 group. rescue 709.67+18.47 dexamethasone 910.2 51.66 Total given had significant statistical difference 0.004 between two groups, 1.23 1.17 0.4 0.56 However, at 2hr, 4hr, 8hr, 12hr, 18hr hr VAS scores (p value <0.0001). is better than prolonging plexus block.
