A comparative study of dexmedetomidine and fentanyl as adjuvants to ropivacaine on analgesic efficacy in supraclavicular brachial plexus block

Background: Various adjuvants have been added to improve the quality of supraclavicular brachail plexus block and prolong postoperative analgesia. The aim present study was compare onset duration sensory motor blockade provided by dexmedetomidine fentanyl as ropivacaine in such block. Methods: In this 60 patients with American Society Anesthesiologists grade I/II scheduled for elective upper limb surgeries were randomly allocated into two groups. Group A received 30 mL 0.5% 1 µg kg-1 dexmedetomidine, group B brachial adverse events during perioperative period noted. Results: 13.47±1.73 min 22.87±2.27 respectively 14.80±2.20 24.33±2.63 which statistically significant (P<0.05). significantly higher compared (826±58.29 vs 592±51.62 minutes, p< 0.0001). Conclusions: Dexmedetomidine provides faster longer when used an adjuvant without any side effects.
