Context: Supraclavicular brachial plexus block is the most flavored technique for upper limb surgeries in the day-to-day anesthetic practice. Adjuvants are commonly used along with local anesthetics to improve the overall quality of block. Dexmedetomidine is a α2 adrenoceptor agonist, nowadays gaining popularity due to its favorable outcomes. Aims: The aim of this study is to compare the block characteristics of 0.5% 30 ml ropivacaine alone with 0.5% 30 ml ropivacaine combined with 50 mcg of dexmedetomidine. Settings and Design: This was a prospective randomized controlled study. Materials and Methods: One hundred patients in the age group of 20–60 years, of American Society of Anesthesiologists Grade I and II, scheduled for elective upper limb surgeries were included in this study. Patients were divided into two groups of 50 each to receive either ropivacaine alone (Group A) or ropivacaine-dexmedetomidine combination (Group B). Onset and duration of sensory and motor blockade were assessed. Statistical Analysis Used: Standard qualitative and quantitative tests were used to compare data. P < 0.05 was considered statistically significant. Results: The onset of sensory and motor blockade was faster in Group B when compared to Group A (17.32 ± 2.05 min, 24.23 ± 5.83 min vs. 22.58 ± 1.75 min, 28.61 ± 2.78 min), the duration of sensory and motor blockade was longer in Group B when compared to Group A (635.0 ± 27.12 min, 513.21 ± 26.14 min vs. 501.1 ± 33.14 min, 402.17 ± 18.16 min), and the duration of analgesia was also longer in Group B compared to Group A (338.16 ± 10 min vs. 247.20 ± 12 min). Conclusion: Dexmedetomidine as an adjuvant to ropivacaine fastened the onset of block, prolonged the duration of block, and prolonged the duration of analgesia.
