Tegileridine vs Sufentanil for Postoperative Pain Management and Gastrointestinal Recovery After Major Laparoscopic Abdominal Surgery (TASPER)

June 4, 2026 updated by: Jihong Jiang, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine

Tegileridine Versus Sufentanil for Postoperative Analgesia and Gastrointestinal Tolerability After Major Laparoscopic Abdominal Surgery: A Single-Center, Randomized, Triple-Blind Trial

This study is a single-center, randomized, triple-blind clinical trial designed to compare tegileridine and sufentanil for postoperative analgesia and gastrointestinal tolerability in patients undergoing major laparoscopic abdominal surgery. Participants will be randomly assigned to receive either tegileridine or sufentanil for postoperative patient-controlled intravenous analgesia according to the study protocol. The purpose of this study is to determine whether tegileridine can provide better gastrointestinal tolerability while maintaining non-inferior postoperative pain control compared with sufentanil in this patient population.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Area Under the Curve of Resting Pain Intensity Within 24 Hours After Admission to the PACU
Time Frame: From 0 to 24 hours after admission to the PACU
The cumulative resting pain score within 24 hours after admission to the post-anesthesia care unit (PACU) will be represented by the area under the curve of the numeric rating scale (NRS) scores from 0 to 24 hours. Resting pain intensity will be assessed using an 11-point NRS, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. NRS scores will be measured at 0, 6, 12, 18, and 24 hours after admission to the PACU.
