Cerebrospinal fluid biomarkers versus glasgow coma scale and glasgow outcome scale in pediatric traumatic brain injury: the role of young age and inflicted injury.

The Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) are widely used clinical scoring systems to measure the severity of neurologic injury after traumatic brain injury (TBI), but have recognized limitations in infants and small children. Cerebrospinal fluid (CSF) concentrations of neuron-specific enolase (NSE) and S100B show promise as markers of brain injury. We hypothesized that the initial GCS and 6-month GOS scores would be inversely associated with CSF NSE and/or S100B concentrations after severe pediatric TBI.
