Aim: To assess intra the cal dexmedetomidine as adjuvant for spinal anaesthesia for perianal ambulatory surgeries. Methodology: Sixty adult patients of American Society of Anaesthesiologists physical status I and II scheduled for perianal surgeries of both genders were divided into 2 groups of 30 each. Group I patients received intra the cal 0.5% hyperbaric bupivacaine 6 mg (1.2 ml) with injection dexmedetomidine 5 μg in 0.5 ml of normal saline and group II received intrathecal 0.5% hyperbaric bupivacaine 6 mg (1.2 ml) with 0.5 ml of normal saline. The parameters such as duration of sensory blockade, motor blockade, surgery and ambulation was assessed. Results: There were 14 males and 16 females in group I and 13 males and 17 females in group II. The mean weight in group I was 65.7 kg and in group II was 64.4 kg, height was 158.8 cm in group I and 159.3 cm in group II, ASA grade I was seen in 15 in group I and 15 in group II and grade II was seen in 16 in group I and 14 in group II. The difference was non- significant (P>0.05). The mean duration of sensory block in group I was 434.6 minutes in group I and in group II was 324.6 minutes, duration of motor block was 320.8 minutes in group I and 228.6 minutes in group II. The mean duration of surgery was 28.5 minutes in group I and 30.2 minutes in group II. The time to ambulation was 312.6 minutes in group I and 214.4 minutes in group II. The difference was significant (P< 0.05). Side effects recorded were Nausea/vomiting in 2 in group I and 3 in group II. Shivering seen in 1 in group I and 2 in group II, bradycardia 1 in group I and hypotension 2 in group I and 1 in group II. The difference was significant (P< 0.05). Conclusion: Intrathecaldexmedetomidine provides prolonged post-operative analgesia as compared to normal saline.
