Trends of haemodynamic parameters (mean ± SD) in each group. T0: baseline, T1: start anaesthesia induction, T2: endotracheal intubation, T21, 22, 23: 5, 10, 15 min after endotracheal intubation, T3: skin incision, T4: end of operation, T502, 501: 10, 5 min before awakening, T5: awakening, T6: endotracheal extubation, T61, 62, 63, 64, 65, 66: 5, 10, 15, 20, 25, 30 min after endotracheal extubation, T7: 30 min after operation, T8, 9, 10: 1, 2, 6 h after operation. Group MD: midazolam 0.03 mg/kg for anaesthesia induction. Group NS: normal saline at the rate of 60 ml/h for 15 min before anaesthesia induction + 0.125 ml/kg/h continuous infusion until the end of operation. Group D0.25: dexmedetomidine 0.25 μg/kg for 15 min before anaesthesia induction + 0.5 μg/kg/h continuous infusion until the end of operation. Group D0.5: dexmedetomidine 0.5 μg/kg for 15 min before anaesthesia induction + 0.5 μg/kg/h continuous infusion until the end of operation. Group D0.75: dexmedetomidine 0.75 μg/kg for 15 min before anaesthesia induction + 0.5 μg/kg/h continuous infusion until the end of operation
