The Efficacy and Safety of Loxoprofen Sodium Patch in Relieving Postoperative Pain After Laparoscopic Surgery

Studies have shown that up to 80% of patients experience postoperative pain following laparoscopic surgery due to inflammation caused by surgical incisions and surrounding tissues, necessitating pharmacological relief. Inflammatory mediators released from the soft tissues around laparoscopic incisions not only significantly alters the chemical microenvironment at the peripheral terminals of nociceptors, directly inducing pain, but also sensitizes afferent fibers, contributing to peripheral sensitization. The investigators conducted a multicenter, prospective, randomized controlled clinical study to explore the use of Loxoprofen Sodium Patch for preoperative local incision analgesia in laparoscopic surgery patients. The investigators aim to observe whether this method can effectively alleviate postoperative incision pain, reduce the dosage of postoperative analgesics and the side effects caused using postoperative analgesics, improve patient satisfaction, and provide new ideas for postoperative analgesia in laparoscopic surgery patients, promoting rapid recovery after laparoscopic surgery.
