Summary

Visceral pain following laparoscopic surgery is frequently underestimated, yet it is associated with a range of adverse outcomes. Effective visceral pain management should constitute an essential component of postoperative analgesic strategies following laparoscopic procedures. However, conventional analgesic agents, including μ-opioid receptor agonists, lack specificity for visceral pain. Anrikefon, a novel selective peripheral κ-opioid receptor agonist, demonstrates unique efficacy in alleviating visceral pain with a favorable safety profile. Preliminary studies showed that a single intravenous dose of anrikefon effectively alleviates postoperative pain after abdominal surgery with a low risk of adverse effects. The investigators hypothesize that an appropriate dosing regimen of anrikefon administered via patient-controlled intravenous analgesia (PCIA) pump, as part of a multimodal analgesic strategy, can specifically target and alleviate visceral pain after laparoscopic surgery, thereby achieving comprehensive postoperative analgesia.
