What is a known complication associated with prolonged intubation?

• A. Pulmonary embolism
• B. Tracheal stenosis
• C. Atelectasis
• D. Vocal cord paralysis

Answer: (B)

Prolonged intubation can lead to tracheal stenosis, which is a narrowing of the trachea that often results from pressure necrosis or ischemia caused by the cuff of the endotracheal tube. When an endotracheal tube is in place for an extended period, the cuff exerts continuous pressure against the tracheal wall. This pressure can compromise the blood supply to the tracheal mucosa, leading to inflammation and scarring, which ultimately results in stenosis. Tracheal stenosis can have significant clinical implications, such as difficulty breathing, stridor, and potential respiratory failure. Recognizing this complication is crucial for managing patients who have undergone prolonged intubation, and monitoring for signs of tracheal injury or stenosis is essential in the postoperative care of these patients. In contrast, although some other choices like vocal cord paralysis can also occur due to intubation, they are less commonly related to the duration of intubation compared to tracheal stenosis.
