Eligibility Criteria

Inclusion

  • Weight 45-100 kg (inclusive) and BMI 18.0-30.0 kg/m² (inclusive).
  • Preoperative ASA Physical Status Class I-III.
  • Scheduled for elective general anesthesia in abdominal surgery (single incision ≥5 cm) or orthopedic surgery (limb/joint procedures); completed anesthesia recovery within 4 hours postoperatively, with NRS score ≥4, and willingness to accept protocol-defined analgesia.
  • Ability to comprehend study objectives, operate PCIA devices, and communicate effectively with investigators.
  • Female subjects must be non-pregnant, non-lactating, and agree to use contraception (including partners) for 3 months post-study.
  • Voluntary participation with signed informed consent.

Exclusion

  • Known or suspected allergy/hypersensitivity to any component of the investigational product, other opioids, or contraindicated drugs specified in the protocol .
  • Neurological/psychiatric disorders including:
  • Clinically significant neurological diseases (e.g., epilepsy, cognitive impairment) .
  • History of brain injury, increased intracranial pressure, or psychiatric disorders (e.g., schizophrenia, bipolar disorder, depression, anxiety) that may interfere with safety or study assessments as judged by the investigator .
  • Cardiovascular diseases/history:
  • Severe cardiovascular conditions (NYHA Class II or higher), myocardial infarction, angina, or severe arrhythmia within the past year .
  • Abnormal 12-lead ECG findings during screening (e.g., sinus bradycardia ≤55 bpm, ≥Grade II AV block) deemed unsuitable by the investigator .
  • Resting systolic blood pressure ≥160 mmHg or \<90 mmHg, diastolic ≥100 mmHg pre-surgery .
  • Intraoperative circulatory instability (e.g., hypotension, bradycardia) assessed as high-risk for trial continuation .
  • Respiratory disorders/history:
  • Bronchial asthma, high-risk respiratory depression conditions (e.g., severe COPD ≥GOLD 3, sleep apnea syndrome) .
  • Preoperative SpO2 \<93% (room air) or intraoperative respiratory depression/ventilatory dysfunction deemed unsafe .
  • Paralytic ileus, biliary/pancreatic diseases within 12 months before screening .
  • Major surgery within 3 months prior to screening.
  • Acute/chronic non-surgical pain interfering with postoperative pain assessment .
  • Preoperative anemia: Hemoglobin \<70 g/L or hematocrit \<25% .
  • High bleeding risk:
  • Congenital bleeding disorders (e.g., hemophilia) .
  • Platelet count \<0.75×LLN, PT \>ULN+3s, or APTT \>ULN+10s .
  • Organ dysfunction:
  • Albumin \<35 g/L (untreated) .
  • Liver/kidney function abnormalities: TBIL/ALT/AST/ALP ≥1.5×ULN ; Creatinine ≥1.5×ULN or clinically significant renal impairment; Recent dialysis (within 28 days) .
  • Random blood glucose ≥11.1 mmol/L during screening (preoperative) .
  • Participation in other clinical trials with active treatment within 3 months before surgery .
  • Other conditions deemed unsuitable by the investigator for safety or protocol compliance.
