Prognosis in children with head injury: an analysis of 340 patients.

BACKGROUND: The outcome in children with head injury is distinctive because of the different biophysical properties of the child's skull and brain, and their reaction to injury. METHODS: In this retrospective study of three hundred and forty children with head injury, managed from January 1993 to December 1998, at NIMHANS, the factors influencing outcome were analyzed. RESULTS: On admission there were 40 children in GCS 3-5, 55 children in GCS 6-8, 96 in GCS 9-12 and 152 children in GCS 13-15. Eleven patients were under 2 years of age, 53 were between 3-5 years, 140 were between 6-10 years and 156 were between 11-15 years of age. The prognosis in various intracranial pathologies due to head injury was evaluated and outcome assessed at discharge. There were 95 children with EDH and 8.4% had poor outcome (vegetative state or death). There were 85 patients with contusion and poor outcome was noted in 18.8%. One hundred patients had diffuse cerebral oedema on CT scan and outcome was poor in 25% of these patients. The clinical features associated with poor prognosis were, absence of ocular movements (50%), abnormal pupillary size and reaction (49%) and age less than 2 years (27%).
