MARTELL, Miguel et al. Assessment of glycemia in enteral feeding to preterms between 1.000 and 2.000 grams. Arch. Pediatr. Urug. [online]. 2017, vol.88, n.5, pp.261-268. ISSN 0004-0584.


although there are controlled studies about different aspects of enteral feeding to preterm neonates, in most cases it is based on standardized and consensus recommendations.


to find out about the changes that occur in plasma glucose within 3 hours following enteral administration of different amounts of lactose.


nineteen preterm infants were studied, 30 to 35 weeks of gestational age, weight ranged from 1.000 to 2.000 grams with a postnatal age from 8 to 18 days old. All of them were fed every 3 hours. Group 1 consisted of 8 infants who received an average of 1.59 g/kg of lactose per lactation (range 1.36-2.20) and group 2 consisted of 11 infants who received an average of 0.83 g/kg of lactose (range 0.62-1.12) per lactation. The glucose level was measured before the feeding and one, two and three hours after the feeding.


a significant increase in glucose levels was found in both groups during the first hour compared to levels before the feeding. Median increase was 30.7 mg/100 ml for group 1, median increase was 10.5 mg/100 ml for group 2. During the second and third hour after feeding group 1 continued with GP levels significantly higher than the previous level, whereas the levels of group 2 were not different from the previous value.


the amount of lactose administered affects the evolution of postprandial glycemia for a period of three hours. It evidences a significant increase in the first hour and subsequently decreases 2 and 3 hours after feeding. Those who received a higher amount of lactose would be more likely to have GP values above the previous value before feeding again, what resulted in a higher carbohydrate loading.
