Pilot Date on Swallow Function in Nondysphagic Patients Requiring a Tracheotomy Tube

Abstract

Objective. To evaluate the effects of occlusion status (i.e., open, finger, capped) of the tracheotomy tube and removal of the tracheotomy tube that may have upon bolus flow and durational measurements in nondysphagic persons requiring a tracheotomy tube.Study Design. Prospective, single subject, repeated measure design.Methods. Participants had their swallow evaluated with 5 mL pureed boluses using nasal endoscopy with the tracheotomy tube in place, removed, and under the following occlusion conditions: open, finger, and capped. The order of occlusion condition was randomized.Results. Aspiration was never observed but laryngeal penetration was a common finding. Durational measurements for swallow initiation and duration of white out were not significantly different by occlusion status or after removal of the tracheotomy tube.Conclusion. This study provides corroborating evidence demonstrating the lack of a relationship between a tracheotomy tube and swallowing dysfunction.
