ReviewStress hyperglycemia in pediatric critical illness: the intensive care unit adds to the stress!
Stress hyperglycemia (SH) commonly occurs during critical illness in children. The historical view that SH is beneficial has been questioned in light of evidence that demonstrates the association of SH with worse outcomes. In addition to intrinsic changes in glucose metabolism and development of insulin resistance, specific intensive care unit (ICU) practices may influence the development of SH during critical illness. ⋯ Tight glucose control (TGC) to manage SH has emerged as a promising therapy to improve outcomes in critically ill adults, but results have been inconclusive. Large variations in ICU practices across studies likely resulted in inconsistent results. Future studies of TGC need to take into account the impact of commonly used ICU practices and, ideally, standardize protocols in an attempt to improve the accuracy of conclusions from such studies.

Glycemic control in the pediatric intensive care unit of Leuven: two years of experience.
Stress hyperglycemia and hypoglycemia are associated with increased mortality and morbidity in critically ill patients. Three randomized controlled trials, in the surgical, medical, and pediatric intensive care unit (PICU) of the Leuven University in Belgium, demonstrated the beneficial response of tightly controlling blood glucose levels within age-adjusted narrow limits by applying intensive insulin therapy. ⋯ Differences between the adult and the PICU are described. This overview article might help other ICUs by addressing potential differences in clinical practice when implementing TGC.

Clinical TrialEvaluation of a continuous blood glucose monitoring system using central venous microdialysis.
Glycemic control in critically ill patients has been shown to be beneficial. In this prospective study, we evaluated the accuracy and technical feasibility of a continuous glucose monitoring system using intravascular microdialysis. ⋯ Central venous microdialysis using the Eirus monitoring system is a highly accurate and reliable method for continuous blood glucose monitoring up to 48 h in ICU patients undergoing cardiac surgery. The system may thus be useful in critically ill ICU patients.

Clinical TrialUse of an intravascular fluorescent continuous glucose sensor in subjects with type 1 diabetes mellitus.
Stress hyperglycemia in the critically ill is associated with increased morbidity and mortality. Continuous glucose monitoring offers a solution to the difficulties of dosing intravenous insulin properly to maintain glycemic control. The purpose of this study was to evaluate an intravascular continuous glucose monitoring (IV-CGM) system with a sensing element based on the concept of quenched fluorescence. ⋯ The IV-CGM system was capable of achieving a high level of glucose measurement accuracy. However, superficial peripheral veins may not provide adequate blood flow for reliable indwelling blood glucose monitoring.

Clinical TrialHyperglycemia control of the nil per os patient in the intensive care unit: introduction of a simple subcutaneous insulin algorithm.
Diabetes patients in the intensive care unit (ICU) and either nil per os, on enteral feedings, or on total parenteral nutrition are often treated with sliding-scale insulin (despite lack of evidence showing benefit) or intravenous insulin (IVI) infusion, a nursing intensive procedure requiring hourly glucose measurements, and insulin rate adjustments. We introduced a subcutaneous insulin algorithm (SQIA) that would equal the glucose goals for IVI but have the simplicity of q4 hour adjustable sliding-scale insulin. ⋯ A simple SQIA allows insulin doses to be adjusted to the individual patient's needs and meet current ICU goals for glycemic control. Its adoption may reduce the workload of nurses.
