Risk factors associated with prolonged intubation and laryngeal injury.
A prospective study evaluated potential risk factors associated with laryngeal injury after prolonged endotracheal tube intubation for longer than 3 days. Ninety-seven patients were evaluated after oral endotracheal tube intubation (mean, 9 days). This study updates a previously reported evaluation of 44 patients. ⋯ Eight patients had true vocal cord immobility noted initially after extubation, and the remaining eight had true vocal cord immobility an average of 4 weeks after extubation. Initial and delayed true vocal cord immobility were associated with duration of intubation and size of endotracheal tube (p < 0.01). Delayed true vocal cord immobility developed only in patients with a size 8 endotracheal tube.(ABSTRACT TRUNCATED AT 250 WORDS)
