Abstract

Objective
This study was designed to evaluate the effect of nasogastric tube on swallowing function in stroke patients with dysphagia.


Method
Twelve stroke patients with dysphagia were included in this study. We evaluated the Functional Dysphagia Scale using videofluoroscopic swallowing study. Swallowing tasks were composed of swallowing 5 cc of thick food and same volume of fluid on nasogastric tube insertion state and then nasogastric tube removal state.


Results
As the result of measuring oral phase score before and after removing nasogastric tube, all of 12 patients showed no significant difference. There was statistically significant increase in score of residue in piriform sinuses on thick food swallowing after removing nasogastric tube (p<0.05). After removing nasogastric tube, aspiration was decreased on fluid swallowing in cases of 2 patients, while aspiration on thick food swallowing was increased in cases of 2 patients, compared with nasogastic tube insertion state.


Conclusion
As the result of this study, the stroke patients with dysphagia on nasogastric tube were increased on fluid aspiration due to rapid descending and inhibition of epiglottic closure compared with the removal state of nasogastric tube. And there was significant increased in scores of residue in piriform sinuses on thick food swallowing and aspiration pneumonia after removing nasogastric tube.
