BACKGROUND: The clinical significance of hyperglycemia after pediatric traumatic brain injury is controversial. This study addresses the relationship between hyperglycemia and outcomes after traumatic brain injury in pediatric patients.

METHODS: We identified trauma patients admitted during a single year to our regional pediatric referral center with head regional Abbreviated Injury Scale scores > or = 3. We studied identified patients for admission characteristics potentially influencing their outcomes. The primary outcome measure was Glasgow Outcome Scale score.

RESULTS: Patients who died had significantly higher admission serum glucose values than those patients who survived (267 mg/dL vs. 135 mg/dL; p = 0.000). Admission serum glucose > or = 300 mg/dL was uniformly associated with death. Admission Glasgow Coma Scale score (odds ratio, 0.560; 95% confidence interval, 0.358-0.877) and serum glucose (odds ratio, 1.013; 95% confidence interval, 1.003-1.023) are independent predictors of mortality in children with traumatic head injuries. CONCLUSION Hyperglycemia and poor neurologic outcome in head-injured children are associated. The pathophysiology of hyperglycemia in neurologic injury after head trauma remains unclear.
