Figure 2: Graphs represent the changes in hemodynamic parameters 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 (saline) from admission to the operating room until the end of operation. Comparisons are made with repeated measures analysis of variance and unpaired t-test. HR: heart rate, SBP: systolic blood pressure, DBP: diastolic blood pressure, MAP: mean arterial pressure. Hemodynamic parameters were measured and recorded at the time of admission to the operation room (T0), after bolus administration of dexmedetomidine (T1), after anesthesia induction (T2), 1 min after intubation (T3), after incision (T4) and after sternotomy (T5). *P < 0.05 for comparison between groups at the same time; #P < 0.05 for comparison of the values with the first measurement
