ABSTRACT: Esophageal dysmotility is common in infants. We aimed to evaluate the influence of milk temperature on esophageal motility using multichannel intraluminal impedance-pH monitoring (MII-pH). Five healthy lambs, ages 2 to 3 days, underwent a MII-pH whereas bottle-fed randomly with 50 mL of ewe milk at 26°C, 38.5°C, and 41.5°C. Impedance motility parameters were studied on 5 swallows at each temperature. At 38.5°C we noted a higher total propagation velocity and a shorter total bolus transit time (TBTT) (P < 0.05). These unique results suggest a potential role of milk temperature alterations in improving oral feeding in infants with esophageal dysmotility.
