This study aims to assess the impact of the administration route of dexamethasone (intravenous vs. perineural) on postoperative pain and inflammatory response in pediatric patients undergoing hip surgery. The primary outcome is postoperative pain intensity measured using an age-appropriate scale at multiple intervals. Secondary outcomes include inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), opioid consumption, time-to-first rescue analgesia, and overall patient recovery. This randomized, double-blinded study seeks to improve pain management strategies and optimize anesthesia protocols in pediatric arm surgery.
