To determine the association between organ dysfunction and hyperglycemia in critically ill children receiving intravenous insulin. Retrospective chart review (cohort study). Pediatric intensive care unit in a university hospital. n = 110 patients; inclusion criteria: ICU hospitalization from May 2005 to May 2006; insulin drip to manage hyperglycemia. Exclusion criteria: insulin drip <48 h; diabetic patients. Duration of hyperglycemia: sum of hours of hyperglycemia (≥126 mg/dl). Hypoglycemia (blood glucose <40 mg/dl). Organ dysfunction was determined per International Pediatric Sepsis Consensus Conference criteria. Multiple logistic regression models determined the association between ≥3 compared to <3 organ dysfunctions and hyperglycemia, hypoglycemia, and mortality, after adjustment for confounding variables (age, gender, PRISM score, vasopressors, steroids). Organ dysfunction ≥3 compared to <3 after adjustment for confounders was associated with intermittent hyperglycemia of ≥24 h (OR 6.1, CI 1.8–21.2; p = 0.004). Hyperglycemia trended towards significance with mortality [3.2 (CI 0.9–11.6, p = 0.079)]. Hypoglycemia, after adjusting for the above, was not associated with mortality. Organ dysfunction (≥3 versus <3) was significantly associated with hyperglycemia for ≥24 h and hypoglycemia. Hyperglycemia trended toward significance with mortality in critically ill children. There was no association between hypoglycemia and mortality.

    We analyzed the association between the day 1 glucose values in 209 children admitted to the PICU and the outcome (mortality). 58 (27.7%) children had hyperglycemia while 18 (8.6%) children had hypoglycemia, on day 1 after admission. Hypoglycemia was associated with higher mortality. This is...

    Background: Severity of illness is an important consideration in making the decision to transfuse as it is the sicker patient that often needs a red cell transfusion. Red blood cell (RBC) transfusions could potentially have direct effects and interact with presenting illness by contributing to...

    Need and purpose of review: Hyperglycemia is prevalent among critically ill pediatric patients. Previously thought to be an adaptive response to stress, hyperglycemia is now recognized to be associated with an adverse outcome. Correction of such hyperglycemia with insulin infusion has been shown...
