A Study Evaluating Sedation of Intravenous Administration of HSK3486 Injectable Emulsion in ICU Patients Undergoing Mechanical Ventilation
Study Details
Study Description
Brief Summary
This is a multi-center, randomized, single-blind, propofol-controlled phase III clinical study. In this study, ICU patients undergoing mechanical ventilation are expected to be enrolled and will be randomly assigned to the HSK3486 group and the propofol group.

Outcome Measures
Primary Outcome Measures
- Success rate of sedation [Within 24 hours of administration]
1) The time period during which the RASS is in the range of +1 to -2 accounts for ≥ 70% of the total duration of study administration and 2) Remedial treatment is not used.
Secondary Outcome Measures
- Mean qualified rate of sedation [Within 24 hours of administration]
Defined as the percentage of time period during which the RASS is in the range of +1 to -2 relative to the total duration of study administration
- Use of study drug [Within 24 hours of administration]
the loading doses of HSK3486 and propofol, mean maintenance dose and total dose per unit weight per hour of HSK3486 or propofol, and the number of dose modifications and the number of top up doses during the maintenance period
- Dose of remedial drugs per unit weight [Within 24 hours of administration]
the mean dose per unit weight per hour of other sedatives used to maintain the target sedation (RASS within +1 to -2 points)
- Time to extubation [Within 24 hours after administration]
the time from intubation (applicable to patients who undergoes intubation after entering the ICU)/ICU admission (applicable to patients with intubation before entering the ICU) to extubation or the time from drug discontinuation to extubation
- Time to recovery [Within 24 hours after administration]
the time for the subject to recover from sedation to full recovery of consciousness (RASS ≥ 0) after discontinuation of drug administration
- Incidence of adverse events [From day -1 to 24 hours after administration]
