Laryngeal sequelae following prolonged endotracheal intubation are being observed with increasing frequency as this technique of airway management is being employed for extended periods of time. Many etiologic factors have been implicated in the development of these problems with the exact reasons being as yet unknown. After reviewing the records of 372 consecutive patients intubated over an 18-month period, we have observed an increased frequency of these complications in the diabetic female patient and suggest that early tracheostomy should be considered in these individuals when the use of prolonged intubation is anticipated. The possible pathophysiology of this problem in the diabetic, as well as the non-diabetic intubated patient, and its possible prevention will be discussed.
