title: Hypoglycemia in newborn infants at risk.
abstract: Infants of diabetic mothers (IDM), large (LGA) or small (SGA) for gestational age and late preterm (LPT) infants are at risk for hypoglycemia. We report the incidence, the consequences and the impact of a recently implemented guideline. From 1 January to 31 December 2012 we screened infants at risk. The first blood glucose was done within 90 min after birth, 30 min after the first feeding and had to be repeated before each feeding. Hypoglycemia was defined as blood glucose below 40 mg/dL independent of age; all babies remained in the study for at least 24 h or until at least 3 glucose measurements were >40 mg/dL.
  
  
  RESULTS
  We identified 259 out 1 074 (24.1%) infants and included 145 (56.0%) of these infants in a retrospective analysis. 17 (11.7%) infants (male:female=1:1.1) showed 19 episodes of hypoglycemia. 3 of them had more than one risk factor, 2 were LGA at term. 6 (35%) out of 17 infants had to be transferred, one due to clinical signs and 5 according to the protocol. Mean number of blood glucose measurement was 6.9±1.9. The number of procedures performed to detect one episode of hypoglycemia was 54.
  
  
  CONCLUSIONS
  The incidence of hypoglycemia in infants at risk is low and does not justify screening such a large risk group, which may harm them by requiring a disproportionately large number of blood withdrawals.
