Malnutrition may worsen the prognosis of critically ill children with hyperglycemia and hypoglycemia.

Objectives: To determine whether hyperglycemia and hypoglycemia are associated with higher mortality, longer length of intensive care unit (ICU) stay, and fewer ventilator-free days in critically ill children while taking into account the clinical severity and nutrition status.

Patients And Methods: A prospective observational cohort study was conducted on 221 children admitted to the ICU. Blood glucose levels were analyzed in the first 72 hours.
