3. Medical history or evidence of any of the following prior to screening/at baseline, which may increase sedation/anesthesia risk:

1. History of cardiovascular diseases: Uncontrolled hypertension or SBP >160 mmHg and/or DBP >100 mmHg despite antihypertensive treatment, severe arrhythmia, heart failure, Adams-Stokes syndrome, unstable angina, myocardial infarction within 6 months before screening, history of tachycardia/bradycardia requiring medication, third-degree atrioventricular block or QTcF interval ≥450 ms (Fridericia's correction formula, see Appendix 2) during screening;

2. Respiratory system disorders: Respiratory insufficiency, history of obstructive pulmonary disease, history of bronchospasm requiring treatment within 3 months prior to screening, acute respiratory tract infection with obvious symptoms such as fever, wheezing, or productive cough within 1 week prior to baseline;

3. History of cerebrovascular disease: History of craniocerebral injury, convulsions, epilepsy, intracranial hypertension, cerebral aneurysm, or cerebrovascular accident; history of schizophrenia, mania, chronic use of antipsychotics, or cognitive impairment;

4. Gastrointestinal disease history: Gastrointestinal retention, active hemorrhage, or circumstances that may lead to reflux and aspiration;

5. Patient with a history of uncontrolled and clinically significant liver, kidney, blood system, nervous system or metabolic system diseases judged by the investigator to be unsuitable for this trial;

6. History of alcohol abuse within 3 months prior to screening, abuse defined as average of >2 units of alcohol per day (1 unit = 360 mL beer or 45 mL liquor with 40% alcohol or 150 mL wine);

7. History of drug abuse within 3 months prior to screening;

8. Serious infection, trauma, or major surgery within 4 weeks prior to screening;

4. Any one of the following respiratory risks before/during screening:

1. Asthma history, and stridor;

2. Sleep apnea syndrome;

3. History of malignant hyperthermia or family history;

4. History of failed tracheal intubation;

5. Judged by the investigator to have difficult airway or judged as difficult tracheal intubation (modified Mallampati score III or IV );

5. In receipt of any of the following drugs or therapies prior to screening:

1. Participated in other drug trials within 1 month prior to screening;

2. In receipt of medications that may affect QT interval within 2 weeks prior to screening (see Appendix 5);

3. In receipt of medications that induce or inhibit cytochrome P450 isoenzyme CYP2B6 within 2 weeks prior to screening (see Appendix 6);

4. In receipt of propofol, other sedatives/anesthetics, and/or opioid analgesics or compounds containing analgesics within 3 days prior to screening.

6. Laboratory results meeting any of the following criteria during screening/at baseline, confirmed by re-examination:

1. Neutrophil count ≤1.5×109/L;

2. Platelet count <80×109/L;

3. Hemoglobin <90 g/L (no blood transfusion within the last 14 days);

4. ALT and/or AST ≥2.0×upper limit of normal (ULN);

5. Total bilirubin ≥2.0×ULN;

6. Serum creatinine ≥1.5×ULN.

7. Women who are pregnant or breastfeeding; women of child-bearing potential or men who are unwilling to use contraception during the trial; subjects who are planning pregnancy within 1 month after the completion of the trial (including male subjects);

8. Subjects judged by the investigator to be unsuitable for participating in this trial for any reason.
