Hysterectomy Clinical Trials

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 objective is to determine if a single application of an equivalent dose of Tegileridine or Oxycodone can keep VAS scores at or below 3 during the anesthesia recovery phase. The secondary objectives are to compare cumulative opioid consumption within 48 hours postoperatively, time to first rescue analgesia, and the incidence rate of adverse events, such as nausea, vomiting, 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.
