Placebo Comparator
Insulin, Travasol (35%) postop
Insulin, Travasol (20%) postop
Insulin, no protein after surgery
Insulin (hyperinsulinemic-normoglycemic clamp) with Travasol (amino acid supplementation) given from start of surgery to 6 hours after, at an amount of 35% of patient's energy expenditure as measured before surgery, .
Insulin (hyperinsulinemic-normoglycemic clamp) with Travasol (amino acid infusion), given from start of surgery to 6 hours after, at an amount of 20% of patient's energy expenditure as measured before surgery.
Insulin (hyperinsulinemic-normoglycemic clamp, an insulin infusion between 2 and 5 microunits/kg with glucose at a variable rated titrated to maintain normoglycemia, blood glucose 4-6 mmol/L) with no protein supplementation from start of surgery to 6 hours after.
