About

Aetiology of dysphagia after extubation is unknown and considered to be multifactorial. Use of a standardized dysphagia- screening permits an early diagnosis. This study is to evaluate a new GUSS (gugging swallowing Screen) tool with multi-consistency check for intensive care patients (GUSS-ICU) with dysphagia. The concurrent validity (in terms of sensitivity and specificity) of the GUSS-ICU is analyzed in comparison to the flexible endoscopic evaluation of swallowing (FEES).

Full description

Aetiology of dysphagia after extubation is unknown and considered to be multifactorial. Use of a standardized dysphagia- screening permits an early diagnosis. This study is to evaluate a new GUSS (gugging swallowing Screen) tool with multi-consistency check for intensive care patients (GUSS-ICU) with dysphagia. The concurrent validity (in terms of sensitivity and specificity) of the GUSS-ICU is analyzed in comparison to the flexible endoscopic evaluation of swallowing (FEES).

The GUSS-ICU with multi-consistency check includes an indirect and a direct swallowing attempt. In indirect swallowing, the vigilance is first assessed on the basis of the RASS score (Richmond agitation-sedation scale), the presence of a stridor, the effectiveness of coughing and screeting, the possibility of swallowing saliva, drooling (saliva) and the change of voice after swallowing. If six points are reached, one can immediately proceed to the direct swallowing attempt. Unlike the original GUSS, the new GUSS-ICU direct swallowing test consists of 4 subtests with pulpy, liquid, solid and mixed solid-liquid consistency. The mixed solid-liquid consistency has been supplemented, as mixed consistencies require a more complex swallowing function with increased tongue- and lip coordination.
