lateral postion: The children will be positioned on their sides with their heads elevated by 30°, a thin pillow behind their backs, the upper legs bent, and the lower legs straightened.
supine position: The children will be changed to a supine flat-lying position for extubation.
Study summary
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.

Primary outcome measure(s)
the occurrence of postoperative respiratory adverse events (PRAEs) — during PACU PRAEs include a diverse array of respiratory complications, including laryngospasm, bronchospasm, apnea, airway obstruction, stridor, cough/choking, hypoxemia.
