Severe traumatic coma in infancy and childhood: results after surgery and resuscitation.

This study deals with 390 cases of severe traumatic coma in infancy, childhood and youth, aged between 4 months and 19 years. Cases in which unconsciousness lasted less than 24-48 hours have not been considered here. 161 patients were operated upon for intracranial space-occupying lesions or for open head injury: extradural haematomas 60; extradural haematomas + brain lacerations and/or subdural haematomas 16; acute subdural haematomas 18; brain laceration 36; open head injuries 17; decompressive operations, hydromas and contusions 14. 102 patients recovered and 59 died. 229 subjects were given only to resuscitation treatment. 164 recovered and 65 died. Recovery and mortality rate are discussed in relation to the pathologicial lesions and to the clinical picture (severity, evolution and duration of coma). Overall mortality rate was 31%. Mortality was higher in operated patients (36.6%) and lower in patients in whom space-occupying lesions were not demonstrated by angiography and who underwent only resuscitation treatment (28%). The lowest rate was observed in cases of extradural haematoma (25.4%) and open head injury (23%). Highest mortality rate have been observed in cases of decerebrated coma (with or without signs of low brain stem impairment). Complete recovery can be achieved even after prolonged decerebration. 31 patients showed the typical picture of the "apallic syndrome": in 28 cases after prolonged decerebrated coma, in 3 cases after coma without decerebration. Of our 31 cases, 4 died, 4 are still in a chronic apallic state and 23 recovered. Of these, 10 patients had a remarkable recovery and 13 remained severely disabled.
