Overfeeding-associated hyperglycemia and injury-response homeostasis in critically ill neonates

Injury severity induces a proportionate acute metabolic stress response, associated with increased risk of hyperglycemia. We hypothesized that excess caloric delivery (overfeeding) during high stress states would increase hyperglycemia and disrupt response homeostasis. Gestational age, daily weight, total daily caloric intake, serum C-reactive protein (CRP), prealbumin, and blood glucose concentrations in all acutely-injured premature NICU infants requiring TPN over the past 3years were reviewed. Injury severity was based on CRP and patients were divided into high (CRP ≥50mg/L) versus low (CRP f)=0.0353). When high stress patients were separated into high caloric intake (≥70kg/kcal/day) versus low caloric intake (
