You may not qualify if:

  • Individuals with a known history of allergy to any component of the investigational drug, or with an allergy or contraindication to anesthetic/analgesic drugs used during surgery;
  • Patients with the following conditions or medical histories:
  • Comorbid with stroke, Parkinson's syndrome, cognitive impairment, or a history of epilepsy (excluding convulsions caused by high fever in childhood),
  • Patients with craniocerebral injury, increased intracranial pressure, or brain tumors,
  • History of difficult airway, obstructive sleep apnea syndrome, bronchial asthma, chronic respiratory system diseases, other severe respiratory system diseases, or acute upper respiratory tract infections within 2 weeks;
  • History of myocardial infarction or angina within 6 months before screening, or history of severe arrhythmias such as Ⅱ or higher degree atrioventricular block, with a history of New York Heart Association (NYHA) heart function classification class II or above;
  • History of vestibular dysfunction or motion sickness, or dizziness, nausea, dry retching/vomiting within 1 week before screening;

  • Randomized blood glucose ≥11.1 mmol/L or glycated hemoglobin ≥9% during the screening period;
  • Patients with a clear diagnosis of clinical hypothyroidism;
  • Presence of other acute or chronic pain conditions before surgery or comorbid with other physical pain that could confound the evaluation of postoperative pain.
  • Hypertension that has not received regular antihypertensive treatment or is poorly controlled despite treatment: during the screening period, systolic blood pressure greater than 160 mmHg, or diastolic blood pressure greater than 100 mmHg (excluding abnormalities during the peri-anesthetic period).
  • Patients with a systolic blood pressure less than 90 mmHg during the screening period (excluding abnormalities during the peri-anesthetic period);
  • Peripheral capillary oxygen saturation (SpO2) \<92% in a non-oxygen-supplemented state (excluding abnormalities during the peri-anesthetic period) at screening;
