Background: Dexmedetomidine, an exceptionally specific α2 agonist, is applied as a powerful adjunct to numerous local analgesics in territorial anesthesia. Researchers led the current research to determine suitability of dexmedetomidine concluded two courses, i.e. intravenous and perineal courses with ropivacaine for the obstruction of the supraclavicular brachial plexus in elective medical procedures of the lower arm. Methods: Our current research was conducted at Mayo Hospital, Lahore from March 2018 to February 2019. After institutional freedom of ethical counseling, 70 patients matured between 19 to 62 years of age, having a place with ASA class I and II were randomly separated into two gatherings of 35 apiece after detailed instructional consent. The DPN cluster obtained 0.6% ropivacaine 29 ml + 2 ml dexmedetomidine 55 μg perennially and 100 ml of typical 0.8% saline intravenously. The IVD collection obtained 0.6% ropivacaine 29 ml + 2 ml of typical 0.8% saline perennially and 55 μg dexmedetomidine in 100 ml of typical 0.9% saline intravenously. The essential goals were to recognize time of tangible onset, motor start, time for full motor and tactile square, absolute term for tangible and motor square, and the entire duration of pain-free time. Optional goals were hemodynamic parameters, sedation scores, and antagonistic occasions. Evidence-based strategies were demonstrated using SPSS for Windows (Adaptation 23.0). Results: Statistical patient profiles such as age, gender, height, weight, BMI remained compared in mutually sets. Tangible and motor onset time and full square time of touch and motor were earlier in the DPN group than in the IVD set. Tangible square length was delayed in the PND group (687.34 ± 53.23 min) compared to the IVD set (374 ± 39.97 min) [p < 0.002]. In addition, square root term was basically extended in the PND group (595.52 ± 59.13 min) associated to IVD set (316.51 ± 27.48 min) [p < 0.002]. In addition, the total duration of freedom from pain was substantially longer in the PND set (702.84 ± 45.93 min) than in the IVD set (406.17 ± 31.87 min) [p < 0.002]. Two patients experienced bradycardia and one patient experienced hypotension in the IVD group. Ramsay sedation scores in both sets were < 4. Conclusion: Dexmedetomidine is an outstanding adjunct to ropivacaine for supraclavicular square. Perineal dexmedetomidine suggests superior square superiority and delayed pain-free period, in contrast to intravenous dexmedetomidine which has insignificant symptoms. Key words: Dexmedetomidine, Ropivacaine, brachial plexus block.
