Brief summary: This study is designed as an open label, single dose combination of HSK3486 and etomidate in healthy adult male subjects. The study will evaluate the anesthetic/sedation effect of the combination of the 2 drugs and the safety profile including pain on injection, hypotension, tachycardia or bradycardia effects (HSK3486), and involuntary muscle movements, nausea and vomiting potential and adrenal suppression (etomidate).

All subjects will be administered HSK3486 plus etomidate. Subjects will be confined to the study unit from the evening of Day -1 until the morning of Day 2, then will be required to return for a follow up visit on Day 7.

Intensive PD, PK, safety and tolerability and assessments will be performed prior to dosing on Day 1 until 24 hours post-dose (Day 2).

* 8.Ability to provide written informed consent
* 9.Willing and able to follow study instructions and likely to complete all study requirements
* 10.Suitable venous and arterial access.

Exclusion Criteria:

* 1.History of allergy or sensitivity to: propofol, etomidate or components of HSK3486 (excipients soy bean oil, glycerine, triglycerides, purified egg phospholipids, sodium oleate and sodium hydroxide), or plain lignocaine
* 2.History of clinically significant problems with anesthesia induction
* 3.Current smoker, or a history of regular (more than weekly) use of tobacco- or nicotine-containing products within 2 months prior to screening
* 4.History of excessive alcohol intake (more than 4 standard drinks daily, on average) or use of recreational drugs within the last 3 months prior to screening
* 5.Intake of \> 8 caffeine-containing drinks per day, on average, or approximately 800mg of caffenine daily on average; history of intolerance of abstinencce from caffeine for 3 days
* 6.Use of prescription or over the counter medications within 7 days of investigational product administration, with the exception of paracetamol, oral non-steroidal anti-inflammatory agents, topical over the counter preparations and routine vitamins (if they do not exceed the recommended daily dose), unless agreed as non-clinically relevant by the investigator and sponsor.
* 7.Standard donation of blood within 30 days of the study
* 8.Donation of plasma or participation in a plasmapheresis program within 7 days of investigational product administration
* 9.Receipt of any investigational study drug within 30 days prior to screening
* 10.Unable to fast for the 6 hours prior to investigational product administration
* 11.Clinically significant (as judged by the investigator) presence of acute illness (e.g. gastrointestinal illness, infection such as influenza, upper respiratory tract infection) at admission to the clinical study unit
* 12.Anticipated need for surgery or hospitalization during the study
* 13.Craniofacial abnormality that would potentially interfere with airway management under unconscious sedation or anesthesia
* 14.History of seizures or epilepsy
* 15.History of ischaemic heart disease
* 16.History of brady- or tachy-dysrhythmias requiring medical care
* 17.History of asthma, with bronchospasm requiring treatment in the last 3 months
* 18.Any condition, which in the investigator's opinion, puts the subject at significant risk, could confound the study results or may interfere significantly with the subject's participation in the study
* 19.Receipt of HSK3486 less than 4 weeks prior to the start of the study.
