A Clinical Trial Evaluating the Efficacy and Safety of HSK3486 Injectable Emulsion in Elective Surgery Patients

The induction dose is 0.4mg/mg. The initial maintenance dose of the first 6 subjects is 1 mg/kg/h. For the subsequent enrolled subjects, the investigator could adjust the subsequent initial maintenance dose according to the dose response of the first 6 subjects, so as to explore the optimal initial maintenance dose. The range of the initial maintenance dose is 1 (± 0.5) mg/kg/h, i.e. the minimum initial maintenance dose should not be less than 0.5 mg/kg/h, and the maximum should not be more than 1.5 mg/kg/h.

The induction dose is 2.0mg/mg. The initial maintenance dose of the first 2 subject is 5 mg/kg/h. For the subsequent enrolled subjects, the investigator could adjust the subsequent initial maintenance dose according to the dose response of the first 2 subjects, so as to explore the optimal initial maintenance dose. The adjustment range of the initial maintenance dose is 5 (± 2.5) mg/kg/h, i.e. the minimum initial maintenance dose should not be less than 2.5 mg/kg/h, and the maximum should not be more than 7.5 mg/kg/h.

The induction dose of Propofol is 2.0mg/mgThe initial maintenance dose of HSK3486 is fixed at 1 mg/kg/h, without adjustment.
