Developmental delay signals a higher likelihood of airway and respiratory challenges during sedation. Children with developmental disorders often have hypotonia, craniofacial differences, and potential airway anomalies, all of which can weaken airway patency and respiratory effort. Sedation further depresses central respiratory drive and protective reflexes, so small reductions in tone or airway tone can lead to partial or complete airway obstruction and hypoxemia. Because these kids may also have coexisting sleep-disordered breathing or reduced pulmonary reserve, episodes of desaturation during sedation are more common—studies and clinical experience show about a threefold increase in desaturation risk in this population.

Understanding this helps guide safer planning: thorough preoperative airway assessment, consideration of the minimum effective sedative depth, readiness to manage airway obstruction, and continuous monitoring with pulse oximetry and capnography, along with having a plan for escalation should desaturation occur. The other conditions listed do not inherently carry the same combination of developmental delay and substantially elevated desaturation risk during sedation, so they don’t explain the association as clearly.
