Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Successful Anesthesia Induction

    The primary outcome of interest was the success rate of anesthesia induction, defined by the proportion of subjects with successful anesthesia. A subject was considered successful for anesthetic induction if the following conditions were met: induction success Modified Observer's Assessment of Awareness/Sedation Scale (MOAA/S ≤1) after administration of study drug and 1 or less top-up dose required without using any rescue drugs. Where Grade 0 is no response after trapezius squeeze, Grade 1 responds only after painful trapezius squeeze and Grade 5 is completely awake responds to name spoken in normal tone.

    From start of drug administration to MOAA/S ≤1 (up to 5 minutes)

Secondary Outcomes (4)

  • Subjects' NRS Pain Score

    Up to 8 hours

  • Proportion of Subjects With Successful Induction Who Maintain the Desired Depth of Anesthesia for General Elective Surgery, AND Without Significant Cardiac and Respiratory Depression.

    15 minutes from end of drug administration.

  • Proportion of Subjects With Any Injection-site Pain on Numeric Rating Scale.

    From start of drug administration to MOAA/S ≤1 (up to 5 minutes)

  • Time to Successful Induction of General Anesthesia.

    From end of drug administration to MOAA/S ≤1 (up to 5 minutes)

Other Outcomes (2)

  • Time to the Disappearance of Eyelash Reflex

    From end of drug administration to disappearance of eyelash reflex (up to 5 minutes)

  • Number of Participants That Failed to Meet Successful Induction of General Anesthesia

    From start of drug administration to MOAA/S ≤1 (up to 5 minutes)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects undergoing elective surgery (nonemergency, noncardiothoracic, and nonintracranial surgery anticipated to last at least 1 hour ).
  • Males or females, aged ≥18 years old, with American Society of Anesthesiologists Physical Status (ASA PS) I to IV.
  • Body mass index (BMI) ≥18 kg/m2.
  • For all females of childbearing potential, negative pregnancy test at screening and baseline. Additionally, females of childbearing potential must agree to use birth control (such as condom, intrauterine device \[IUD\], abstinence) from the time of consent until 30 days post study drug administration.
  • Capable of understanding the procedures and methods of this study, willing to sign an Informed Consent Form, and to complete this study in strict compliance with the study protocol.

You may not qualify if:

  • Contraindications to deep sedation/general anesthesia or a history of adverse reaction to sedation/general anesthesia.
  • Known to be allergic to eggs, soy products, opioids and their antidotes, or propofol; subject having contraindications to propofol, opioids, and their antidotes.
  • Medical condition or evidence of increased sedation/general anesthesia risk.
  • Any medication that has the potential to interact synergistically with propofol or HSK3486, including but not limited to all sedatives and hypnotics.
  • Laboratory parameters significantly out of range at screening.
  • Female subjects with a positive pregnancy test (serum or urine) at screening or baseline; lactating subjects; any subject planning to get pregnant within 1 month after the study (including the male subject's partner).
  • Judged by the investigator to have any other factors that make the subject unsuitable for participation in the study.
