About this trial
The postoperative recovery period following general anesthesia has been associated with a 30%-50% incidence of postoperative respiratory adverse events (PRAEs) in pediatric populations, including laryngospasm, airway obstruction, and hypoxemia. 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.
