Title: Effect of Tegileridine on Postoperative Bowel Function Recovery in Abdominal Surgery: A Multicenter, Randomized, Controlled Trial
The goal of this clinical trial is to evaluate the effectiveness and safety of tegileridine, a biased ฮผ-opioid receptor agonist, for patient-controlled intravenous analgesia (PCIA) after abdominal surgery.
The main question it aims to answer is:
Is tegileridine superior to morphine in promoting the recovery of gastrointestinal function within 72 hours after abdominal surgery?
Researchers will compare the experimental group (receiving Fumarate Tegileridine Injection) to the active control group (receiving Morphine Hydrochloride Injection). Both groups will also receive dexmedetomidine in their PCIA pumps. This comparison will determine if tegileridine is more effective for bowel recovery and has a better safety profile.
