Abstract
Six trauma patients and five healthy volumteers were given an intravenous glucose
infusion (5 Gm. per hour) for 6 hours. The serum insulin response and urine insulin
excretion were measured and compared in the two groups. Glucose intolerance and serum
insulin levels which were elevated but inappropriately low for the degree of glycemia
characterized the trauma patients. Urine insulin concentrations and total urine insulin
were increased significantly in the trauma patients. Renal function was similar in
both groups, as determined by serum creatinine, blood urea nitrogen, and creatinine
clearance. The increase in urine insulin concentration in the trauma patients reflected
the higher serum insulin concentrations, but no correlation existed between serum
insulin and urine insulin concentrations. A negative correlation was found between
“insulin clearance” and serum insulin in both groups, indicating altered renal handling
of insulin following injury which may be a contributory factor to the relative hypoinsulinemia
of trauma.
