Hyperglycemia Increases Muscle Blood Flow and Alters Endothelial Function in Adolescents with Type 1 Diabetes

Figure 1

Serum glucose values during hyperinsulinemic hyperglycemia insulin clamp (solid circle) and the euglycemia control clamp (X). Fasting glucose values are indicated by the vertical line. The average time to achieve euglycemia was 57 ± 11 minutes during the hyperglycemia clamp and 70 ± 17 minutes during the euglycemia control clamp. During euglycemia study, normal saline was given to match volume of dextrose 20% given during hyperglycemia study.
