Background:
Few studies have evaluated the prevalence of post-extubation dysphagia and associated factors in patients with coronavirus disease 2019 (COVID-19) . Our study assessed the prevalence of post-extubation dysphagia and body composition in patients with COVID-19 discharged from an intensive care unit (ICU).
Methods:
A prospective cohort study was performed in post-ICU extubated patients with acute respiratory distress syndrome related to COVID-19 in two referral hospitals. A total of 112 patients were evaluated and included; swallowing assessment and bioelectrical impedance analysis (BIA) were performed after extubation and discharge from the ICU. To identify associations between dysphagia, lower phase angle (PhA) (<4.8°) and hydration (extracellular water/total body water < 0.390) logistic and linear regression analyses were conducted.
Results:
The incidence of post-extubation dysphagia was 41% (n = 46). From these, 65% (n = 30) had severe swallowing impairment. Overhydration and PhA were significantly different in patients with dysphagia, and segmental hydration in the trunk and legs was higher than in arms. PhA <4.8° (odds ratio [OR], 12.2; 95% CI, 4.3-34.1; P < .05) and overhydration measured by BIA (OR, 9.1; 95% CI, 3.4-24.5; P < .05) were associated with post-extubation dysphagia in multivariate analysis. PhA (<4.8°) was associated with a lower rate of swallowing recovery at hospital discharge (log-rank test = 0.007).
Conclusions:
A high incidence of post-extubation dysphagia was found in patients with COVID-19. Low PhA and overhydration were associated with the presence of dysphagia. Lower PhA was an independent factor for swallowing recovery at discharge.
