Which combination increases aspiration risk in critically ill children?

Which combination increases aspiration risk in critically ill children?

• A. Decreased strength and coordination of pharyngeal muscles and weak cough reflex
• B. Strong cough reflex
• C. Normal gastric emptying
• D. Adequate airway reflexes

Answer: (A)

Airway protection relies on coordinated swallowing and an effective cough. When pharyngeal muscles are weak and poorly coordinated, swallowing is inefficient and residue can spill toward the airway. If the cough reflex is also weak, the child cannot clear any material that does enter the airway, allowing aspiration to occur. In critically ill children, this combination markedly increases aspiration risk. By contrast, a strong cough reflex, normal gastric emptying, and intact airway reflexes enhance protection and reduce the chance of aspiration.
