Figure 3: Graph represents the changes in pain score in two groups: dexmedetomidine (received 1 μg/kg of intravenous infusion of Precedex for 10 min and then maintenance dose (0.5 μg/kg/h) until the end of operation) and control (placebo) from admission to the operating room until after sternotomy. Comparisons are made with Mann–Whitney U-test. There were no significant differences between two groups at similar times, however pain score was significantly elevated in 4 and 6 h after transfer to Intensive Care Unit and the time of extubation compared to the time 2 h post-Intensive Care Unit (P < 0.05)
