[Intubation damage to the larynx. Manifestations, comments on pathogenesis, treatment and prevention]

A variety of lesions can be seen in the larynx subsequent to an intubation anaesthesia or treatment with a respirator. The larynx may already be injured by introducing an endotracheal tube. The inserted tube must necessarily chafe the laryngeal mucosa. Many studies are concerned with individual manifestations [5-10,14,16,17,20]. The following article gives an overview of the intubation lesions of the larynx observed by us and offers comments on pathogenesis and prevention.

161 patients with severe lesions subsequent to an intubation or treatment with a respirator were seen at the ENT Department of the University of Marburg Hospital from 1973 to 1995. TYPES OF LESIONS CAUSED BY INTUBATION: Basing on the pathomechanisms, we can classify the lesions as follows: inflammatory reactions, lesions of the larynx caused during intubation, lesions caused by chafing by the tube or by the sealing sleeve.

Considering the large number of performed intubations, lesions of the larynx occur rarely. However, in view of the possible sequels, it would be advisable if an experienced laryngologist would perform a careful endoscopic examination of the larynx and trachea at least after every forced or prolonged intubation and especially after every treatment with a respirator.
