Preventive Analgesia With Anrikefon in Laparoscopic Cholecystectomy

This study will determine the optimal timing for Anrikefon administration. It will also assess the quality of patient recovery. Laparoscopic cholecystectomy (LC) is a routine surgical procedure. However, the incidence of acute visceral and incision pain is high, reaching 50% to 70%. This pain significantly impairs patient recovery. Anrikefon is novel peripherally restricted κ-opioid receptor agonist. It has very low brain penetration. This property reduces central nervous system side effects and respiratory depression. Preventive analgesia blocks the transmission of nociceptive stimuli to the central nervous system. It reduces postoperative pain sensitization and intensity. Currently, research on Anrikefon for preventive analgesia in LC patients is limited. It impacts on the recovery process is not yet fully understood. This study will compare drug administration before anesthesia induction with intra-operative administration. Participants will be assigned to one of two groups with equal probability using computer-generated random numbers. Patients in the Preventive Analgesia group will receive Anrikefon injection 15 minutes before anesthesia induction. Bridging Analgesia group is the control group. Patients in this group will receive Anrikefon immediately after the gallbladder is detached from the liver. Both groups will receive the identical drug dosage of 1 μg/kg. Both treatment groups will receive identical care beyond the time of Anrikefon administration. All patients…
