Clinical Study of Equivalent Doses of Oxycodone or Tegileridine on Patients Undergoing Gynecological Laparoscopic Hysterectomy

Summary

This randomized, double-blind, controlled study aims to evaluate the efficacy and safety of Tegileridine or Oxycodone for postoperative analgesia in patients undergoing Total Laparoscopic Hysterectomy（TLH）. Subjects will be randomly assigned to receive an equivalent dose of intravenous Tegileridine or Oxycodone as part of a standard postoperative analgesia regimen. All patients will have access to rescue opioid analgesia according to the protocol. The primary outcome measures are the incidence of postoperative nausea and vomiting in two groups receiving a single dose of equivalent morphine analgesics (Group Tegileridine or Group Oxycodone).The secondary endpoints were designed to compare the success rate of postoperative analgesia, cumulative opioid consumption within 48 hours postoperatively, the time to first rescue analgesia, and the incidence of adverse events such as sedation, respiratory depression, pruritus, and constipation. Safety will be monitored throughout the study via predefined stop-and-report procedures. The study results will evaluate whether teglitazide provides a more effective, better-tolerated analgesic regimen for patients undergoing total laparoscopic hysterectomy.
