Associating Factors Regarding Nasogastric Tube Removal in Patients With Dysphagia After Stroke

Objective To demonstrate associating factors regarding nasogastric tube (NT) removal in patients with dysphagia after stroke. Methods This study is a retrospective medical chart review. Patients were divided into non-brain stem (NBS) and brain stem (BS) groups. A videofluoroscopic swallowing study was conducted until swallowing functions were recovered. Initial disease status was measured using the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS). Risk factors related to stroke were evaluated. The penetration-aspiration scale (PAS) was used as the swallowing test. Functional status was measured by Mini-Mental Status Examination (MMSE) and Modified Barthel Index (MBI). Within each group, initial evaluations and their subsequent changes were compared according to the NT removal status. Correlation between the NT removal time and other initial factors were evaluated. Results Ninety-nine patients were allocated to the NBS group and 39 to the BS group. In NBS, age, PAS, MMSE, and MBI were significantly different according to the NT removal status. In BS, smoking and PAS were significantly different. In NBS, changes in PAS, MMSE, and MBI were significantly different according to the NT removal status. In BS, only PAS change was significantly different. In NBS, initial NIHSS, mRS, MMSE, and MBI were correlated with removal time. Conclusion In stroke patients with NT�, younger age, better initial disease and functional status seems to remove NT in NBS stroke. Therefore, when deciding to remove NT, those three factors should be considered discreetly.
