OBJECTIVES: The type of liquid (eg, water or milk) that should be used during flexible endoscopic evaluation of swallowing (FEES) has received little investigation. Aspiration may vary as a function of the thin liquid type used during FEES. METHODS: We measured the effects of liquid type (water, skim milk, 2% milk, and whole milk; all dyed with green food coloring), delivery method (cup and straw), and bolus volume (5, 10, 15, and 20 mL) on Penetration-Aspiration Scale (PAS) scores in 14 healthy older adults (mean, 75 years; range, 69 to 85 years). Each participant generated 32 swallows. RESULTS: The PAS scores differed significantly by liquid type (p = 0.003) and by bolus volume (p = 0.017), but not by delivery method (p = 0.442). The PAS scores were significantly greater for 2% milk and whole milk than for skim milk and water (p < 0.05), and for 20 mL versus smaller volumes. Penetration and aspiration were observed on 113 (25%) and 15 (3%) of 448 swallows, respectively. CONCLUSIONS: These findings suggest that both milk and water should be used during FEES for an accurate assessment of aspiration status.
