GLUCOSE DISAPPEARANCE RATE IN SYMPTOMATIC NEONATAL HYPOGLYCEMIA

[摘要] The present study was undertaken to determine the rate of glucose disposal in the pathogenesis of symptomatic neonatal hypoglycemia. Intravenous glucose (1 gm/kg) was injected rapidly into 11 hypoglycemic and eight control newborn infants. The percentage (mean ± SEM) disappearance rate per minute (Kt) was significantly higher (p < 0.001) in the hypoglycemic newborn infants compared with that of the controls (2.8 ± 0.1 versus 1.2 ± 0.1, respectively). Baseline plasma insulin concentrations were significantly higher (p < 0.01) in the hypoglycemic (16.8 ± 3.9µU/ml) than those of the controls (3.5 ± 1.0µU/ml). Baseline plasma growth hormone values in the hypoglycemic newborns were 16.6 ± 5.7 mµg/ml. Growth hormorne values rose in the hypoglycemic to 36 ± 10 mµg/ml at 10 minutes and to 64 ± 13 mµg/ml by 60 minutes.
