title: Effect of occlusion of a tracheotomy tube on aspiration.
abstract: The purpose of the present study was to investigate the effect of occlusion of a tracheotomy tube on aspiration utilizing fluoroscopy. Twenty consecutive tracheotomized patients referred for a modified barium swallow were included. Selection criteria were ability to tolerate tracheotomy tube occlusion during the modified barium swallow procedure, no surgery of the upper aerodigestive tract except tracheotomy, and no history of oropharyngeal cancer or stroke. There was 100% agreement among 3 independent reviewers on ratings of the presence or absence of aspiration. It was found that the occlusion status of the tracheotomy tube did not influence the prevalence of aspiration. Nine of 10 (90%) subjects who exhibited aspiration were over 65 years of age (mean = 72 years 2 months). No trends were observed for bolus consistency, type of tracheotomy tube, or presence/absence of a nasogastric tube and ratings of aspiration.
