Summary
This prospective, randomized clinical trial aims to evaluate the effect of preoperative nebulized lidocaine and nebulized 3% hypertonic sodium chloride (NaCl) on the incidence of postoperative respiratory complications in pediatric patients undergoing adenoidectomy and/or adenotonsillectomy. Lidocaine, a versatile sodium channel blocker, has shown antitussive, bronchodilatory, and anti-inflammatory benefits when nebulized, and has been safely used in children for respiratory procedures. Hypertonic 3% NaCl is known to improve mucociliary clearance, reduce airway edema, and enhance secretion mobilization, particularly in pediatric respiratory conditions. Both agents have demonstrated individual safety and efficacy in respiratory management, yet their preoperative nebulized use for preventing postoperative respiratory adverse events (PRAEs) in pediatric airway surgery has not been previously studied. This trial seeks to determine whether preoperative nebulization with these agents can reduce postoperative respiratory complications, improve recovery, and enhance perioperative safety in this high-risk population.
