Abstract: Background: The Effects Of Intravenous DEXMEDETOMIDINE On Spinal Anaesthesia: Comparasion Of Different Dose Of DEXMEDETOMIDINE Material and Methods: This is a prospective, randomized, interventional Study. Total sample size is 75. Patients who were undergoing surgeries under Spinal Anaesthesia were divided into three groups, 25 patients in each group. DEX I Group: 0.5 microgram/kg dexmedetomidine iv DEX II Group: 0.3 microgram/kg dexmedetomidine iv DEX III Group: 0.2 microgram/kg dexmedetomidine iv with subarachnoid block with 3ml of 0.5%hyperbaric bupivacaine in all groups. Result: The duration of regression of sensory and motor block was prolonged with higher doses of Intravenous Dexmedetomidine in case of spinal anaesthesia with there is no significant effect on time of onset of spinal anaesthesia. Conclusion: We conclude in our study that with higher dose of intravenous dexmedetomidine as an adjuvant to 0.5% hyperbaric bupivacaine there was significantly prolonged both sensory and motor block along with higher Ramsay sedation score.
