Abstract: ObjectiveTo study predictive value of dysphagia manifestations in clinical physical and vediofluoroscopy exam for aspiration, silent aspiration, pneumonia and nutritional status. MethodsAll kinds of manifestations in clinical and videofluoroscopy were analyzed with chi square test according to number of patients with aspiration, silent aspiration, pneumonia and grades of nutritional status at discharge. Those manifestations with statistic significance were analyzed by Logistic regression to test their quantitive predictive value. ResultsClinical characteristics can predict some manifestations under videofluoroscopy and the manifestations which can predict aspiration, silent aspiration, pneumonia in hospital and nutrition status at discharge were attained.ConclusionThese clinical and imagic predictive manifestations to aspiration, pneumonia and nutrition status are attained, which may be useful to clinical practice.
