Summary
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.

Interventions
Before the surgery, according to the surgeon's incision marking, the patients accept 2ml of triamcinolone (80mg) plus 15ml of 1% ropivacaine diluted with 0.9% saline to a total volume of 30ml infiltrates the incision layer by layer (1ml subcutaneous infiltration at each location, 2ml full layer infiltration, total 3ml).
Before the surgery, according to the surgeon's incision marking, the patients accept 30ml of 0.5% ropivacaine infiltrates the incision layer by layer (1ml subcutaneous infiltration at each location, 2ml full layer infiltration, total 3ml).
