Inter-group Comparisons in Mean Arterial Pressure and Heart Rate

The values are expressed as means ± SD. P values determined by a t-test. Group C: remifentanil-propofol, Group DEX: remifentanil-propofol-dexmedetomidine, MAP: mean arterial blood pressure, HR: heart rate, T-control: at the arrival to operation theater, T-loading: at after the loading of study drugs, T-induction: at 3 min after the start of anesthesia induction, T-trachea: at tracheal intubation, T-incision: at surgical incision, T-incision30: at 30 min after surgical incision, T-extubation: at tracheal extubation. ^*Indicates P < 0.05 vs. Group C at each measured time point.
