Intravenous glucose intake independently related to intensive care unit and hospital mortality: an argument for glucose toxicity in critically ill patients

Abstract

In long-stay ICU patients without blood glucose level control, the ICU and hospital mortality was independently related to the mean amount of infused glucose. In addition, mortality in patients with a mean glucose level above 8.0 mmol/l was higher. Both these determinants of mortality can exert their effects by insulin-independent uptake of glucose with subsequent toxic intracellular effects.
