Effectiveness Of Apneic Oxygenation During Induction Of General Anesthesia In Children Undergoing Adenotonsillectomy (As Partially Obstructed Airway)

During general anesthesia, the administration of anesthetics and muscle relaxants induces apnea, wherein spontaneous breathing ceases . Pediatric patients, characterized by their higher oxygen consumption rate and smaller functional residual capacity, are particularly susceptible to hypoxemia during apneic episodes . This vulnerability to hypoxemia underscores the critical need for effective oxygenation strategies during anesthesia. Apneic oxygenation, the provision of oxygen without concurrent tidal volume delivery, emerges as a vital technique in pediatric anesthesia, playing a pivotal role in both routine and challenging airway management scenarios .

In modern practice, apneic oxygenation during airway management denotes the uninterrupted supply of oxygen, extending the window for maintaining safe oxygen saturation levels during the apneic phase . This technique holds particular significance in pediatric patients undergoing adenotonsillectomy, where the delicate balance of oxygenation is paramount .

Adenotonsillectomy, a common surgical procedure in pediatric patients, poses unique challenges in airway management . The procedure involves the removal of the adenoids and tonsils, often necessitating general anesthesia and temporary airway obstruction . Furthermore, the potential for blood and secretions in the oropharynx increases the risk of airway compromise during the perioperative period. In this context, ensuring adequate oxygenation is essential to mitigate the risk of hypoxemia and its associated complications In this randomized clinical trial, the investigators aim to evaluate the efficacy and safety of apneic oxygenation using nasal cannula in pediatric patients undergoing adenotonsillectomy under general anesthesia. By assessing our primary outcome and secondary outcomes, the investigators seek to contribute valuable insights into optimizing anesthesia management protocols for this vulnerable patient population.
