Intervention

Drug:
• HSK3486
First-stage:after an initial dose of 1mg/kg/h, If the BIS is in the range of 80 to 60 and the continuous RASS score = 3 or one time RASS score = -4, the 0.4 mg/kg/h maintenance dose is administered. The total infusion time was 4h. Second-stage: a single loading dose of 0.2 mg/kg given over 1 minute, then a continuous infusion of maintenance dose 0.35 mg/kg/h for a total infusion time of 12h.
• Propofol
First-stage: after an initial dose of 5mg/kg/h, If the BIS is in the range of 80 to 60 and the continuous RASS score = 3 or one time RASS score = -4, the 0.4 mg/kg/h maintenance dose is administered. The total infusion time was 4h. Second-stage: loading dose of 1mg/kg given over 1 minute, then a continuous infusion of maintenance dose 1.75 mg/kg/h for a total infusion time of 12h.
