Gastric emptying in preterm infants.
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 weeks corresponding to 33-38 weeks of gestational age. A total of 30 studies were performing 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 one hour an average of 24.8 ml of human milk and 19.2 ml of infant formula had left the stomach.
