Capillary-venous differences in concentrations of blood sugar were measured in 55 newborn infants during the first 15 hours of life. The capillary-venous difference is related to the capillary level under fasting conditions. The administration of glucose by gavage in doses of 2 to 3 gm./kg. led to a prompt rise in concentration of glucose in capillary blood and an increase in capillary-venous difference. The administration of .03 µg./kg. of epinephrine led to a prompt increase in concentration of glucose in capillary blood but to a decrease in the capillary-venous difference.
The relation of these findings to homeostatic mechanisms in the newborn was discussed.
