SEVERE HEAD-INJURY IN CHILDREN - EXPERIENCE OF THE TRAUMATIC COMA DATA-BANK

THE OUTCOME AT discharge, 6 months, and 1 year after they had sustained severe head injuries was investigated in children (0-15 yr old at injury) who were admitted to the neurosurgery service at one of four centers participating in the Traumatic Coma Data Bank. Of 103 eligible children, the quality of recovery was assessed by the Glasgow Outcome Scale (GOS) at 6 months after injury in 92 patients (86% of series) and at 1 year in 82 patients (73% of series). The lowest post-resuscitation Glasgow Coma Scale score and pupillary reactivity were predictive of the 6-month GOS as were their interaction. Analysis of the first computed tomographic scan disclosed that bilateral swelling with/without midline shift was related to a poor outcome as was the presence of mass lesions. Comparison of age-defined subgroups of patients revealed that outcome was poorest in the 0- to 4-year-old patients, as reflected by their mortality, which increased to 62% by 1 year. Distinctive features of the injuries in the 0- to 4-year-olds included evacuated subdural hematomas (20% of patients) and hypotension (32% of patients). The most favorable outcome was attained by 5- to 10-year-olds (2/3 had a good recovery by 1 yr), whereas the GOS distribution of adolescents was intermediate between the children and adults. In summary, the GOS data reflect heterogeneity in the quality of outcome after severe head injury depending on age, neurological indices, and computed tomographic scan diagnostic category.
