On the Pathogenesis of Laryngeal Injuries Following Prolonged Intubation

Abstract

Extensive ulcerations appear in the larynx after about 20 hr intubation. The pathogenesis of these ulcerations is discussed on a basis of histological and roentgenological investigations. The authors have found that (a) the ulcerations are pressure sores; (b) the period of intubation should be as short as possible, and should not exceed 24 hr, (c) if possible intubated patients should not lie with their heads bending backwards, (d) in case of prolonged intubation, tubes other than of the Magill type might be used.
