Early glucose normalization does not improve outcome in the critically ill trauma population.

Strict control of serum glucose in critically ill patients decreases morbidity and mortality. The objective of this study was to evaluate the effect of early normalization of glucose in our burn and trauma intensive care unit. From January 2002 to June 2005, 290 patients were admitted with serum glucose 150 mg/dL or greater and 319 patients with serum glucose less than 150 mg/dL. The patients with hyperglycemia were more severely injured and more often required operative intervention within the first 48 hours. The patients with hyperglycemia were at increased risk for infection and mortality. Of those 290 patients in the hyperglycemic cohort, 125 patients had early normalization of serum glucose, whereas 165 patients required more than 24 hours to normalize. The early normalization cohort was younger in mean age than the late group, but these 2 groups were similar in injury severity. Correspondingly, there was no difference in the rate of infection. Although hyperglycemia on admission appears to correlate with a worse outcome, early glucose normalization did not affect morbidity and mortality in our critically ill population.
