Eligibility

Inclusion Criteria:

1. Patients who need tracheal intubation for mechanical ventilation and need 6-24 h of sedation after randomization, as anticipated;

2. The target RASS score is between +1 and -2;

3. 18 = age < 80 years old; with no restriction on gender;

2. Patients having the following medical history or evidence at screening, which may increase sedation/anesthesia risk:

1. Cardiovascular system: Class III and IV heart failure by New York Heart Association (NYHA), Adams-Stokes syndrome; acute coronary syndrome (ACS) within 6 months prior to screening; bradycardia requiring medications and/or heart rate = 50 beats/min; serious arrhythmia history such as Degree II-III atrioventricular block (excluding patients with pacemakers); acute and chronic myocarditis; systolic pressure = 90 mmHg even when large dose of vasoactive drug (such as norepinephrine = 0.6 µg/kg/min) is used;

2. Patients with mental disorders (such as schizophrenia, depression, etc.) and cognitive impairment; past abuse history of psychotropics and anesthetics, and long-term use of psychotropics;

3. Patients with moderate to severe hepatic and renal dysfunctions (liver function:

Child-Pugh Grade B and C, scale in Annex 9; renal function: glomerular filtration rate eGFR = 60 mL/(min•1.73 m2) [eGFR is calculated with the Modification of Diet in Renal Disease (MDRD) formula: eGFR = 186 × serum creatinine (SCr)-1.154 × age-0.203 × 0.742 (female)]; patients under dialysis;

4. Epileptic seizures, convulsions; craniocerebral injury, intracranial hypertension, cerebral aneurysms; Glasgow Coma Score (GCS) = 12 (scale in Annex 6); SOFA > 9 (scale in Annex 7);

5. Expected survival = 72 h;

3. Laboratory measures at screening period meet the following criteria:

1. Neutrophil count = 1.0 × 10^9/L;

2. Platelet count = 50 × 10^9/L;

3. Hemoglobin = 70 g/L;

4. Pregnant or lactating females; fertile females or males reluctant to receive contraception through the study; any subject planning for pregnancy within 1 month after the study (including male subject);

5. Participated in other drug clinical trials within 1 month prior to screening; Other reasons rendering a subject unsuitable for participation in this study as per the judgment of the investigator.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean time to sedation	Defined as the mean time during which the hourly RASS is in the range of +1- -2 during the study treatment	at day 1
Secondary	Study drug use	Including the loading dose, maintenance dose, additional dose of HSK3486 and propofol, average unit weight dose per hour of HSK3486 or propofol, total and hourly average numbers of dose adjustments	at day 1
Secondary	Minimum maintenance dose	Defined as the minimum dose to maintain the target sedation level (RASS between +1 and -2) of the subject for = 2 h and = 4 h during the administration period	at day 1
Secondary	Unit weight dose of remedial drug	Defined as the average hourly unit weight dose of sedatives other than propofol administered for maintaining a target sedation level (RASS between +1 and -2) during the administration period	at day 1
Secondary	Unit weight dose of remifentanil	Defined as the average hourly unit weight dose of remifentanil for analgesia during the administration period	at day 1
Secondary	Extubation time	Defined as the time from ICU admission to extubation (applicable for subjects who have been intubated before admitted to ICU) or the time from intubation to extubation (applicable for subjects who are intubated after admitted to ICU); for withdrawals, the time of extubation is calculated according to the time of discontinuation; if the extubation does not occur within 24 h of administration, the time of extubation is recorded as 24 h	at day 1
Secondary	Recovery time	Defined as the time to recover from sedation status to awaken status (RASS = 0) after drug discontinuation, accurate to the minute; if RASS is = 0 at discontinuation, the recovery time is recorded as 0	at day 1
