Abstract:
ObjectiveTo analyze the correlation between the changes of swallowing function and aspiration in stroke patients using videofluroscopic swallowing study. MethodsFrom January, 2014 to December, 2021, 240 stroke patients who underwent videofluroscopic swallowing study in the radiology department of Xuzhou Central Hospital were retrospectively analyzed. They were divided into aspiration group (n = 108, ≥ grade 5) and non-aspiration group (n = 132, < grade 5) according to Rosenbek Penetration/Aspiration Scale (PAS). The swallowing function changes in the oral and pharyngeal phases were compared between two groups according to Videofluoroscopic Dysphagia Scale, the risk factors of aspiration were analyzed using Logistic multivariate regression. ResultsThere were significant differences in incomplete lip closure, impaired bolus formation, apraxia, incomplete tongue-to-palate contact, premature bolus loss, prolonged oral transit time, delayed triggering of pharyngeal swallow, epiglottis folding dysfunction, pyriform sinus residue, and coating of pharyngeal wall (χ2 > 5.802, P < 0.05). Prolonged oral transit time (OR = 3.964, P = 0.036), delayed triggering of pharyngeal swallow (OR = 5.684, P < 0.001), epiglottis folding dysfunction (OR = 11.571, P < 0.001) and pyriform sinus residue (OR = 4.524, P = 0.002) were correlated with aspiration. ConclusionProlonged oral transit time, delayed triggering of pharyngeal swallow, epiglottis folding dysfunction and pyriform sinus residue are risk factors of aspiration after stroke.
