About

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.

92 participants in 2 patient groups

Tegileridine（T group）

Experimental group

Description:

Around 20 minutes before the end of the operation, patients in the T group were given 0.01 mg/kg of Tegileridine(dissolved in 10 ml of 0.9% sodium chloride injection solution. This was administered via continuous infusion at a rate of 60 ml/h).

Treatment:

Drug: Tegileridine (tegileridine fumarate injection, IV)

Oxycodone（O group）

Experimental group

Description:

Around 20 minutes before the end of the operation, patients in the O group were given 0.06 mg/kg of Oxycodone(dissolved in 10 ml of 0.9% sodium chloride injection solution. This was administered via continuous infusion at a rate of 60 ml/h).

Treatment:

Drug: Oxycodone（Oxycodone Hydrochloride Injection，IV）
