Background: Surgery involving the spine frequently uses spinal anesthesia. It decreases mortality and morbidity, uses fewer medications, results in less blood loss, and provides good postoperative pain management. It is preferred to general anesthesia and epidural anesthesia for intractable operations. Aim and Objective: The present research was aimed to examine effect of Supplementation of low dose Intravenous Dexmedetomidine on characteristics of Spinal Anaesthesia with Hyperbaric Bupivacaine on post-operative analgesia and side effects. Methodology: The present study was carried out on 50 patients undergoing lower abdominal and lower limb surgeries at Santosh Medical College & Hospital. Ages of the patients ranged from 18 to 65, and both sexes' weights ranged from 30 to 70 kg. Result: There were 32 men and 18 women in the study's sample. As opposed to 39.36±13.43 years in groups C, the mean age in groups D was 36.28±12.70 years. For 90 minutes following the administration of the medication, the mean VAS score in the D & C group remained 0. Rescue analgesia took 177.25±28.90 seconds to provide in the C group versus 181.25±41.48 seconds in the D group. (p=0.725) Conclusion: Dexmedetomedine administered intravenously during spinal anesthesia therefore reduced postoperative pain and painkiller usage, according to the study's findings
