Comparison of dexmedetomidine and clonidine as the adjuvants with hyperbaric bupivacaine in subarachnoid block for lower limb orthopaedic surgeries

Abstract

Aim: To compare dexmedetomidine versus clonidine as the adjuvants with hyperbaric bupivacaine in subarachnoid block for lower limb orthopedic surgeries. Material and method: The present study included 160 patients undergoing lower limb orthopedic surgery under subarachnoid block at Department of anaesthesia, Mahatma Gandhi Missions Institute of Health Sciences, Navi Mumbai, Maharashtra. Randomization was a statistical procedure by which the participants have been allocated into 2 different groups i.e. Group C (Clonidine group) and Group D (Dexmedetomidine group). Time of onset of motor block was assessed using Bromage scale. Analgesia duration was observed and recorded following pain scoring system- Visual analogue score (VAS). Results: It was observed that there was statistically significant difference between the total duration of sensory and motor block of the patient in the both groups. The difference in VAS scores were found to be statistically significant among two groups (p
