Introduction Tracheal cannula management (TKM) is performed in patients with dysphagia in most cases with an endoscopic swallow examination (FEES). Within the framework of a prospective study, it was examined whether a long-term measurement with a measuring device that automatically recognizes and evaluates swallows is able to determine comparable results.

Method

In a prospective study (EA1/068/19) swallowing was recorded for two hours before FEES (RheaIngest©, Hasomed). 15 healthy subjects and 15 patients with dysphagia without, with blocked and with unblocked tracheal cannula were examined. After the subsequent FEES, the tracheal cannula status was evaluated.

Results Between January 2018 and March 2019, 61 subjects (♂41(67.2%), ♀20(32.8%)) of whom 19 (31.1%) were healthy and 42 (68.9%) had dysphagia were studied. The median of the measurement parameters of a 2-hour measurement was used for evaluation. A positive correlation was found between the speed and extent of laryngeal elevation and swallowing frequency with the outcome of endoscopic examination.

Conclusion For the first time, swallowing in patients with and without a dysphagia was studied in an automated manner with and without a cannula supply. The results show that with such an examination device an instrument can be provided to evaluate swallowing and its results can support the TKM.
