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.\n\nParticipants who are scheduled for elective abdominal surgery under general anesthesia will:\n\n1. Be randomly assigned to receive either a tegileridine-based or a morphine-based pain relief pump after surgery.\n2. Use the patient-controlled analgesia (PCA) pump for up to 72 hours postoperatively to manage their pain.\n3. Be assessed for the time it takes for their bowel function to return (tolerating food and having gas or bowel movement).\n4.
