Arms Assigned Interventions
Active Comparator: leuven
these patients had their IV insulin controlled by using the protocol adapted from van den Berghe et al. University of Leuven, Belgium, NEJM Nov. 2001
Drug: insulin regular IV infusion
IV insulin was administered by continuous infusion and the rate changed every hour according to the blood glucose level as determined by each of the protocols being compared
Drug: IV insulin infusion
IV insulin was administered by continuous infusion and the rate changed every hour according to the blood glucose level as determined by each of the protocols being compared
Active Comparator: glucommander
these subjects had IV insulin controlled by a computer program called the glucommander described by Davidson, P et al Diabetes Care Oct. 2005
Drug: insulin regular IV infusion
IV insulin was administered by continuous infusion and the rate changed every hour according to the blood glucose level as determined by each of the protocols being compared
Drug: IV insulin infusion
IV insulin was administered by continuous infusion and the rate changed every hour according to the blood glucose level as determined by each of the protocols being compared

Detailed Description:

In 2002 we adapted the protocol described by Van den Berghe et al. for use in our own surgical intensive care unit (SICU) with a target blood glucose range from 80 to 120mg/dL. After five years of implementation, we were able to achieve a mean BG of 117 mg/dL in the SICU. 2% of glucose values were <60 mg/dL in the SICU. Given the concern of safety while optimizing glycemic control, we investigated the etiologies for these hypoglycemic episodes and have found two frequent risk factors; the failure to consistently measure blood glucose every hour and in patients with end stage renal failure.

We will investigate whether a computer-based algorithm for the titration of IV insulin will translate to better clinical outcomes and less hypoglycemia. Therefore, we will conduct a prospective randomized trial comparing the Glucommander, a computer-based algorithm with our Van den Berghe protocol for titration of IV insulin in patients after cardiovascular or transplant surgery. This computer based algorithm was invented in 1984 in Atlanta by Dr. Davidson and Dr. Steed who have used it in a variety of applications of IV insulin.
