Effects of Different Fluids on the Relationship between Swallowing and Breathing during Nutritive Sucking in Neonates

This study in 10 term infants investigated the effects of different fluids on the coordination between swallowing and breathing during bottle feedings. Sucking pressure, swallowing, breathing and O(2) saturation were examined in each infant during bottle feedings with breast milk, formula and distilled water. When receiving breast milk, the infants showed a significantly higher breathing rate than with the other liquids. Swallows followed by inspiration were demonstrated less often with breast milk compared with formula or distilled water. In conclusion, expressed breast milk is suitable for neonates because better coordination between swallowing and breathing could be obtained and subclinical aspiration could be prevented.
