[Contribution of the EEG and evoked potentials in the prognosis of post-anoxic comas in children].
Six children with post-anoxic coma were studied and there was evidence of preserved brainstem function together with the presence of electrocerebral activity on EEG. There is no definite prognosis with slow EEG; patients can either die, survive, but with major neurological damage, or recover completely. In that case, evoked potentials have a good prognostic value. Normal BAEP indicate that patients will survive. However, absence of the cortical component of SEP indicates major cerebral damage. Evolution towards a vegetative state can therefore be predicted.
