  • Patients undergoing emergency surgery or trauma patients;
  • Intraoperative conversion to open laparotomy;
  • History of abdominal surgery within the past 3 months;
  • Patients undergoing liver transplantation or with metastasis to other organs;
  • Patients requiring synchronous resection of organs other than the gallbladder, extrahepatic bile ducts and intestines due to intraoperative clinical needs;
  • Severe renal dysfunction (estimated glomerular filtration rate <30 mL/min/1.73 m²);
  • Laboratory findings or clinical evaluation indicating hypothyroidism or hypokalemia graded ≥ Grade 3 per CTCAE v6.0;
  • Subjects who experienced nausea, retching or vomiting within 24 hours before anesthesia induction (excluding those caused by bowel preparation);
