From: Effects of dexmedetomidine at different dosages on perioperative haemodynamics and postoperative recovery quality in elderly patients undergoing hip replacement surgery under general anaesthesia: a randomized controlled trial

  1. 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
