Able to complete the study in compliance with the requirements of the clinical trial protocol; 3. Subjects (including their partners) are willing to voluntarily adopt an effective measure of contraception starting from screening to 6 months after the last dose of the investigational drug. See the attachment for specific contraceptive measures; 4. Males and females with full capacity for civil conduct, aged ≥ 18 years old (aged between 18 and 64 years old for the non-elderly group and ≥ 65 years old for the elderly group (inclusive)); 5.

For all subjects, the body temperature should be between 35.9-37.6 °C, respiratory rate between 12-20 breaths/min, and SpO2 when inhaling \> 95%; in addition, for subjects in the non-elderly group, the blood pressure should be between 90-140/60-90 mmHg and heart rate between 60-99 bpm; for those in the elderly group, the blood pressure should be between 90-160/60-100 mmHg and heart rate between 50-100 bpm;
Exclusion criteria
1. Smoke more than 5 cigarettes per day on average within 3 months prior to screening; 2. Patient having contraindications to deep sedation/general anesthesia or a history of past sedation/anesthesia accidents; 3. Known sensitivity to HSK3486 excipients (soybean oil, glycerin, triglyceride, egg lecithin, sodium oleate, and sodium hydroxide); or history of drug allergies (including other anesthetics), allergic diseases, or those with hyperactive immuneresponse(allergies to various drugs and foods); 4. History of drug abuse or any signs of long-term use of benzodiazepines (such as insomnia, anxiety, spasms) within 3 months prior to screening; 5. Acute diseases with clinical significance (determined by the investigator) within 2 weeks prior to screening, including GI diseases and infections (such as respiratory or CNS infections); 6. History or evidence of cardiovascular diseases prior to screening: Uncontrolled hypertension \[SBP ≥ 170 mmHg and/or DBP ≥ 105 mmHg without antihypertensive treatment, or SBP \> 160 mmHg and/or DBP \> 100 mmHg despite antihypertensive treatment\], postural hypotension, severe arrhythmia, heart failure, Adams-Stokes syndrome, unstable angina, myocardial infarction within 6 months before screening, history of tachycardia/bradycardia requiring medication, II-III degree atrioventricular block (excluding patients with pacemakers), or QTcF interval ≥ 450 ms (Fridericia's correction formula); 7. Subjects judged by the investigator to be unsuitable for participating in this trial for any reason.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Peak concentration (Cmax) | -30 minutes before administration until 24 hours post administration on day 1 | Cmax(a measure of the body's exposure to HSK3486)will be compared between non-elderly subjects and elderly subjects. |
| Area under the concentration-time curve(AUC) | -30 minutes before administration until 24 hours post administration on day 1 | AUC(a measure of the body's exposure to HSK3486)will be compared between non-elderly subjects and elderly subjects. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Tmax | -30 minutes before administration until 24 hours post administration on day 1 | time to peak observed |
| MOAA/S(modified observer's assessment of alert /sedation) | -5 minutes before administration until 1 hours post administration on day 1 | modified observer's assessment of alert /sedation |
| blood pressure(systolic, diastolic and mean arterial pressure) | from the screening to 2 days post-dose | safety endpoits |
| Total clearance | -30 minutes before administration until 24 hours post administration on day 1 | Total clearance |
| Bispectral index(BIS) | -5 minutes before administration until 1 hours post administration on day 1 | Bispectral index |
