Which factor increases aspiration risk in critically ill children?

• A. Decreased strength and coordination of pharyngeal muscles
• B. Increased saliva production
• C. High coughing ability
• D. Rapid gastric emptying

Answer: (A)

The main risk factor here is impaired airway protection caused by weakened or poorly coordinated pharyngeal muscles. In critically ill children, sedation, neuromuscular weakness, prolonged intubation, or neurologic injury can blunt the pharyngeal constrictors and the timing of the swallow, epiglottic closure, and laryngeal protective reflexes. When swallowing is weak or discoordinated, material from the mouth or stomach can linger or spill into the larynx and trachea before the airway can close or before coughing can clear it, increasing the chance of aspiration. Increased saliva production isn’t inherently a major driver of aspiration risk and is often manageable with suctioning and oral care. A strong coughing ability helps protect the airway by expelling any aspirated material, so it reduces risk. Rapid gastric emptying tends to lower the likelihood of gastric contents lingering and refluxing toward the airway, rather than increasing aspiration risk.
