Postoperative pain remains highly prevalent and inadequately managed in a significant proportion of surgical patients, often leading to delayed recovery, increased opioid consumption, and potential progression to chronic pain. While perioperative systemic dexamethasone is used for its anti-inflammatory and opioid-sparing effects, its efficacy is inconsistent, and concerns regarding systemic side effects persist. Dexamethasone palmitate, a novel lipophilic prodrug formulated as nanoparticle emulsion, leverages the enhanced permeability and retention effect to target inflammatory sites selectively, potentially offering superior anti-inflammatory and analgesic efficacy with reduced systemic exposure. This trial aims to evaluate whether preoperative intravenous dexamethasone palmitate is more effective than conventional dexamethasone in preventing moderate-to-severe postoperative pain.
