Conditions
Brief summary
A two period pilot study to determine if a graded glucose infusion using a glucose (20% dextrose \[D20\]) intravenous infusion can be properly implemented and will be well tolerated in healthy subjects.
Interventions
A stepwise graded infusion of glucose (20% dextrose \[D20\]) with a stable rate of infusion maintained for 40 minutes for each of 5 steps, with steps at 2,4,6,8 and 12mg/kg/min. Procedure will be identical in Period 1 and Period 2.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| proper implementation and tolerability of a grade glucose infusion using D20 intravenous infusion measured by glucose, insulin and C-peptide levels | 0-160 minutes after start of infusion |
Secondary
| Measure | Time frame |
|---|---|
| beta-cell glucose sensitivity (slope of the relationship between insulin secretion rate and glucose) | 0-160 minutes after start of infusion |
