Abstract
Background:Ambulatory anorectal surgery is an appealing approach for patients and physicians due to its increased efficiency and decreased surgical costs. The present study was conducted to evaluate intrathecaldexmedetomidine as adjuvant for spinal anaesthesia for perianal ambulatory surgeries.Materials & Methods:50 adult patients presenting for perianal surgeries were divided into 2 groups of 25 each. Group I patients received intrathecal 0.5% hyperbaric bupivacaine 6 mg (1.2 ml) with injection dexmedetomidine 5 μg in 0.5 ml of distilled water and group II received intrathecal 0.5% hyperbaric bupivacaine 6 mg (1.2 ml) with 0.5 ml of distilled water. The parameters such as time to regression of sensory blockade, motor blockade, ambulation, time to void, first administration of analgesic wasassessed.
Results: The mean weight in group I was 64.7 kg and in group II was 63.4 kg, height was 156.8 cm in group I and 157.3 cm in group II, ASA grade I was seen in 15 in group I and 16 in group II and grade II was seen in 10 in group I and 9 in group II. The difference was non- significant (P>0.05). The mean duration of surgery was 26.5 minutes in group I and 28.2 minutes in group II. The mean duration of sensory block in group I was 430.6 minutes in group I and in group II was 318.6 minutes, duration of motor block was 324.8 minutes in group I and 230.6 minutes in group II and time to ambulation was 314.2minutes in group I and 216.1 minutes in group II. The difference was significant (P< 0.05). Side effects were shivering seen in 1 in group II, bradycardia 1 in group I, hypotension 1 in each group and Nausea/vomiting 1 in group I and 2 in group II. The difference was significant (P< 0.05).
Conclusion: Intrathecaldexmedetomidine provides prolonged post-operative analgesia.
