Which factor is NOT predictive of swallowing problems after intubation?

• A. Age
• B. Duration of intubation
• C. Presence of edema
• D. Infection

Answer: (A)

Age does not independently predict swallowing problems after intubation. The strongest predictors are physical and inflammatory changes caused by the intubation process: longer duration of intubation increases exposure of swallowing muscles and laryngeal tissues to trauma and disuse, making weakness and discoordination more likely. Edema in the laryngeal or pharyngeal areas narrows the airway and disrupts the timing of the swallow, raising the risk of aspiration. Infection adds inflammatory burden, worsening edema and tissue sensitivity, which further impairs swallow function. While older age may be present with other risk factors, it by itself does not reliably forecast post-extubation dysphagia.
