Abstract
The gastric emptying of meals of human milk and infant formula was studied in 11 healthy preterm (AGA) infants at a postnatal age of 1-9 wk corresponding to 33-38 wk of gestational age. A total of 30 studies were performed using a marker dilution technique. Gastric emptying of meals of human milk followed a biphasic emptying pattern with an initial fast phase. In about 25 min half of the meal had left the stomach. The emptying of meals of adapted infant formula usually followed a linear pattern and half the meal had left the stomach after 51 min. After 1 h an average of 24.8 ml of human milk and 19.2 ml of infant formula had left the stomach.
