Inclusion criteria: 1.Aged >= 18 years; 2.American Society of Anesthesiologists (ASA) physical status classification I–III; 3.Body mass index (BMI): 18 kg/m² <= BMI <= 30 kg/m²; 4.Patients scheduled to undergo laparoscopic hepatectomy under general anesthesia with estimated operation duration <= 5 hours; 5.Agree to participate in this trial and voluntarily sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1. History or evidence of any of the following conditions prior to screening: a) Severe cardiopulmonary disease (myocardial infarction, heart failure, or respiratory failure) b) History of neurological or psychiatric disorders: traumatic brain injury, intracranial hypertension, schizophrenia, mania, etc., which, as assessed by the investigator, render the subject unsuitable for participation in the study; c) History of gastrointestinal disorders: intestinal obstruction or other gastrointestinal disorders that the investigator determines may cause nausea or vomiting; or a history of other gastrointestinal disorders deemed unsuitable for study participation by the investigator; d) History of marked, chronic dizziness, or a clearly diagnosed vestibular disorder other than motion sickness (including but not limited to: peripheral vestibular syndrome, central vestibular syndrome, etc.); 2.Patients undergoing emergency surgery or trauma patients; 3.Intraoperative conversion to open laparotomy; 4.History of abdominal surgery within the past 3 months; 5.Patients undergoing liver transplantation or with metastasis to other organs; 6.Patients requiring synchronous resection of organs other than the gallbladder, extrahepatic bile ducts and intestines due to intraoperative clinical needs; 7.Severe renal dysfunction (estimated glomerular filtration rate = Grade 3 per CTCAE v6.0; 9.Subjects who experienced nausea, retching or vomiting within 24 hours before anesthesia induction (excluding those caused by bowel preparation); 10.Patients expected to require postoperative mechanical ventilation via endotracheal intubation or naso/orogastric tube placement for more than 24 hours; 11.Known allergy or contraindication to opioids and other anesthetics, antiemetics that may be administered during the trial. 12.Use of drugs with analgesic, antiemetic or anti-inflammatory effects with unknown half-life within 14 days prior to randomization; or the interval between the last administration and randomization is shorter than 5 half-lives or the duration of drug effect (whichever is longer). Such drugs include, but are not limited to, opioid analgesics, non-opioid analgesics, antiemetics (or drugs with antiemetic properties), sedative-hypnotics, sedative anesthetics, glucocorticoids and other drugs with analgesic or antiemetic effects. 13.Subjects with any other factors deemed by the investigator(s) to render them unsuitable for participation in this clinical study.
