Does the presence of a tracheostomy tube impact swallow function?
Critically Appraised Topic
Limited and low level evidence indicates that the presence of a tracheostomy tube alone (cuff deflated, with no occlusion via cap or speaking valve ) has no causal effect on the parameters of swallow function investigated. It is suggested that the patients underlying diagnoses and co morbidities are the cause of any apparent dysphagia. It is important to note that the literature critiqued indicates mixed results as to whether the manipulation of the tube (e.g. cuff up or down) and the presence of a speaking valve elevates the risk of aspiration. However, exploration of this issue was not within the scope of this CAT. PDF Format.
