Description
Aim: On the dysphagic patients, we investigated the threshold volume of the pharyngeal swallowing elicited by water infusion into oropharynx, and also discussed the potentiality of swallowing training with infusion of chilled carbonated water. Subjects and Methods: Subjects were 5 dysphagic patients due to CVA. All were within 4 weeks after onset. We confirmed their decreased initiation of swallowing reflex without aspiration for small volume of liquid swallowing by preceding Videofluorography. For oropharyngeal infusion, we inserted a polyethylene infusion catheter orally and fixed it on the base of tongue. The site of fixation was monitored by laryngoscope nasally inserted. The types of liquid were:(1) room temperature water (21-23°);(2) chilled water (12-14°);(3) chilled carbonated water (12-14°). We examined infusion volume of 3 swallowing actions. Results: The mean threshold volume of chilled water was less than that of room temperature water and significantly lesser in chilled carbonated water. We considered chilled stimulation and physical stimulation of effervescence might have affected this result. Then we suppose infusion of chilled carbonated water can be applied to swallowing training for patients who decreased elicitation of swallowing reflex because relatively small volume of water infusion (<1ml) can elicit reflex.
