Despite the limited effects of existing pharmacological and operative interventions, positional optimization (e.g., lateral or semirecumbent position) may play a potential role by decreasing airway resistance and improving oxygenation. However, evidence-based evidence for its use in pediatric populations is still lacking, necessitating the urgent need for randomized controlled trials.",[78,79,80,81],"Perioperative Respiratory Adverse Events","Adenoidectomy","Tonsillectomy","Children","NOT_YET_RECRUITING","2025-07-31",{"date":85,"type":86},"2025-08-06","ACTUAL",{"date":88,"type":72},"2025-08-20",{"date":90,"type":72},"2026-08-27",{"name":5,"class":6},1]
