The Efficacy and Safety of Loxoprofen Sodium Patch in Relieving Postoperative Pain After Laparoscopic Surgery
15. juni 2026 opdateret af: Fang Luo, Beijing Tiantan Hospital
The Efficacy and Safety of Incisional Preemptive Analgesia Using Loxoprofen Sodium Patch in Patients Undergoing Laparoscopic Surgery: a Multi-center Randomized Controlled Trial.
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.

The wound healing score is evaluated by independent researchers based on the wound healing score table, which includes three aspects: skin healing, incision infection, and hair growth.
The total score is obtained by adding up the three scores.
Excellent wound healing: 3 points; Good wound healing is 4-5; Poor wound healing: total score greater than or equal to 6 points.

Postoperatively and patient and observer scar assessment scale: the observer scores the scar based on the distribution of blood vessels around the incision, color, scar thickness, surface roughness, area, and softness.
Each score ranges from 1 to 10 points and higher scores indicating more severe scars; The patient evaluates the scar based on whether there is pain or itching, color, softness, thickness, and self-perception.
Each score range is also 1-10 points, with 1 point indicating no difference from normal skin and a higher score indicating more severe scars.
