Hernia Repair

Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after laparoscopic surgery, but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. 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. Preemptive incisional infiltration using local anesthetics with corticosteroids which have potent local anti-inflammatory properties may play a key role in preventing or reducing postoperative pain. The objective of this trial is to determine whether preemptive incisional infiltration with ropivacaine plus triamcinolone is superior to ropivacaine alone in relieving postoperative pain for adults undergoing laparoscopic surgery. We also compare the effects of the two intervention measures on postoperative pain management, patient safety, and recovery quality.

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.
