Many studies over the past decade have demonstrated that clinical outcomes can be improved in critically ill adults by aggressive management of hyperglycemic with insulin infusions (Van Den Berghe 2001, Van Den Berghe 2006, Krinsey 2004, Treggari 2008, Scalea, 2007, Lang 2007). Yet, in some of these studies and other recent trials (i.e. Glucontrol (Preiser, 2009) VISEP (Brunkhorst, 2008) and (NICE-SUGAR, 2009)), have highlighted the potential and real risks of glycemic control (namely iatrogenic hypoglycemia) and questioned how effectively glucose can be controlled in critical illness. One reason for the suboptimal glycemic control witnessed in some trials may be not rigorously refined and validated. Even as such, many medical oversight committees (including the Institutes of Healthcare Improvement, the American Diabetes Association, and Society of Critical Care Medicine, among others) continue to recommend regular and aggressive glycemic control in critically ill patients. Although not specifically included nor excluded from such recommendations, most pediatric intensivists have not incorporated glycemic control into regular practice primarily due to concerns of therapy induced hyperglycemia - although there are reports of protocols that appear to be effective at controlling BG levels with low rates of hypoglycemia (Preissig et al 2008, Verhoeven et al 2009).
