Dexmedetomidine, an α2 agonist drug providing stable hemodynamic conditions, good quality of intraoperative and prolonged postoperative analgesia with minimal side effects. Aim and Objective: To compare and evaluate bupivacaine and bupivacaine with dexmedetomidine in subarachnoid block for below umbilical surgeries. Material and Methods: It was prospective, randomized, double blind study conducted at tertiary care centre over a period extending from January 2014 to October 2015. The study included a total of 100 patients divided into two groups (each of 50 patients) i.e. control and study groups depending upon drugs administered. Results: The onset of sensory block as well as time for attaining maximum sensory level was significantly faster (p < 0.05) in study group as compared to control group. Also, regression of sensory block was slower and onset of motor block is quicker in patients those who received intrathecal dexmedetomidine. There was a significant prolonged duration of sensory analgesia among study group. Summary and Conclusions: Use of0.5% hyperbaric Bupivacaine (15mg) with dexmedetomidine (5mcg) in subarachnoid block Leads to significantly quicker onset of Motor and Sensory block also a minimal intraoperative and postoperative complication as compared to 0.5% hyperbaric Bupivacaine Keywords: bupivacaine, dexmedetomidine.
