Effects of carbonated thickened drinks on pharyngeal swallowing with Flexible Endoscopic Evaluation of Swallowing in patients of oropharyngeal dysphagia - Effects of carbonated thickened drinks with Flexible Endoscopic Evaluation of Swallowing

Penetration aspiration scale was significantly lower in the carbonated thickened drink than the thin water (p<0.05). Swallowing reflex initiation was significantly different between the thin and thickened drink (p<0.01) ; moreover, post hoc analysis revealed that it was significantly lower in the carbonated thickened drink than the thin water (p<0.01). The subjective difficulty of swallowing in the carbonated thickened drink was significantly lower than the thickened water (p<0.05).
