[Postintubation Tracheal Stenosis in a Lightly Sedated Patient under a 10-day-long Mechanical Ventilation]

We report a case of severe laryngeal edema devel- oped after the trachea intubation for 10 days. A 78- year-old woman presented with pulmonary edema due to fluid administration for acute pancreatitis. Endotra- cheal intubation and mechanical ventilation therapy were required for 10 days. The cuff pressures and endotracheal tube positions were routinely checked. A light level of sedation was maintained during mechani- cal ventilation. Ten days later, her trachea was extu- bated. One hour after extubation, she was observed to have inspiratory stridor and she complained of respira- tory distress. Fiberoptic examination revealed laryngeal edema and ulceration of the tracheal mucosa, consis- tent with the lesion where the endotracheal tube cuff had been attached. To maintain the airway, re-intuba- tion and elective tracheostomy were performed. Light sedation during mechanical ventilation may predispose the patient to tracheal injury.
