PURPOSE: Research has shown that prolonged endotracheal intubation can increase risk of aspiration following extubation. This study examined the relationship between swallowing and intubation among patients with COVID-19. We investigated the association between the duration of intubation and time until an oral diet was safely initiated and the correlation between the length of intubation and reduced sensation with aspiration as seen on flexible endoscopic evaluation of swallowing (FEES)/videofluoroscopic swallowing study (VFSS).
METHOD: This study is a retrospective analysis of all intubated patients admitted with the primary diagnosis of COVID-19 between April 2020 and March 2021 who received an inpatient speech-language pathology consultation. We utilized univariate linear regressions to investigate the dose-response relationship between duration of intubation and time until cleared for oral diet post-extubation. Dysphagia outcomes were analyzed, including results from 39 instrumental evaluations (VFSS and FEES).
RESULTS: During this 1-year period, 94 extubated patients were examined by a speech-language pathologist (SLP). We observed a near-exponential increase in the days until cleared for oral diet from 3% versus 69% when intubated for 10-16 days versus 17-34 days, respectively. Second, 39 patients received a VFSS/FEES evaluation. Of those who aspirated on an instrumental swallow study, there was a 78% rate of silent aspiration.
CONCLUSIONS: Prolonged intubation has a near exponential dose-response on the time until a patient becomes cleared for an oral diet after extubation. Prolonged intubation also increases the rate of aspiration observed on VFSS/FEES evaluations. Thus, SLP evaluation of oropharyngeal swallow physiology is important to minimize complications and improve patient outcomes.
