Abstract
Prolonged endotracheal intubation can cause injuries to 1 or more regions of the larynx, making safe extubation impossible and leading to tracheostomy in many patients. Unfortunately, a considerable number of these patients do not benefit from early laryngeal evaluation, which may reveal potentially treatable soft, obstructive tissue before it undergoes irreversible fibrosis. Between July 1992 and December 1995, we performed immediate direct telelaryngoscopy on 142 adults who required tracheostomy because of failed extubation. When present, obstructive tissue was removed with microsurgical techniques. One hundred twenty-nine (90%) patients were decannulated within 3 weeks. The 2 main reasons for failure of early decannulation were intractable granulation (in patients with insulin-dependent diabetes) and coexisting tracheal stenosis. Immediate telelaryngoscopy is recommended in all patients who require tracheostomy because of failed extubation. Flexible laryn-goscopy is not adequate for thorough assessment of laryngeal damage from prolonged intubation.
