[Post-mortem study of laryngotracheal lesions produced by prolonged intubation and/or tracheotomy].
Injuries of the laryngotracheal axis caused by prolonged intubation in critically ill patients raise the issue of the timing of tracheotomy in intubated patients. In 1992 a prospective study was begun in intensive care patients with intubation lasting more than 48 hours. Eight months later, post-mortem data on the laryngotracheal axis of deceased patients was added to our prospective study protocol. The study was closed with 125 cases (52 deceased). The clinical data of 73 surviving patients was compared with that of 18 post-mortem cases. The macroscopic results of the post-mortem study are summarized by grading the lesions according to a personal modification of the Lindholm classification. All cases had laryngotracheal injuries. Only 15% of the lesions were located in the tracheal region. Five cases were classified as grade 2, with an average orotracheal intubation of 9 days, 9 cases as grade 3 with 15 days intubation, and 4 cases as grade 4 with 21 days intubation. We concluded that the severity of laryngotracheal injuries in the early post-mortem exploration was related with the duration of intubation.
