2 september 2026 uppdaterad av: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Efficacy and Safety of Anrikefon Injection for Multimodal Postoperative Analgesia in Patients Undergoing Laparoscopic Hepatectomy:A Single-center, Randomized, Double-blind, Placebo-controlled Clinical Trial

A single-center, randomized, double-blind, placebo-controlled trial design will be adopted to investigate whether Anruikefon can significantly reduce the consumption of sufentanil via PCIA pumps within 48 hours postoperatively compared with placebo.

Exclusion Criteria:

  • Patients with a history of severe cardiopulmonary disease, neuropsychiatric disorders, digestive system diseases, chronic dizziness or vestibular dysfunction;
  • 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);
