Time-course evaluation of blood glucose changes in response to insulin delivery in critically ill patients

Abstract

Intravenous insulin by infusion is commonly used for blood glucose control in the ICU and blood glucose is almost exclusively monitored by intermittent sampling. The rate of change in blood glucose concentration [BG] when the insulin infusion rate is changed is not known, and as a result the optimum time to measure [BG] after changing the infusion rate is unclear.
