Abstract
Term large for gestational age neonates are at increased risk for hypoglycemia. It was postulated that identification of term LGA newborns by the Portland Intrauterine Growth Curve as opposed to the Colorado Intrauterine Growth Curve would allow for the classification of a lesser number of neonates as LGA but would identify the LGA neonates at risk for hypoglycemia. We reviewed retrospectively the charts of 100 inborn neonates born from August through October 1980 who plotted as LGA (wt.> 90th %tile) on the Colorado Chart. 61 of these 100 infants were LGA on the Portland Chart. All 100 neonates were screened for dextrostix values less than 45 mg.% in the first two hours of life. Of the 17 neonates found to have dextrostix < 45 mg.%, 15 had a stat quantitative B.S. performed. All 15 neonates were symptomatic with tremors and jitteriness. 11 out of these 15 neonates had a B.S. <40 mg.%, requiring immediate treatment. All 11 hypoglycemic neonates were identified as LGA on the Colorado Graph whereas only 7 of these 11 neonates were identified by the Portland Graph as LGA. We conclude that in our population the Colorado Graph seems to be a better tool than the Portland Graph in identifying term LGA neonates at risk for hypoglycemia.
