Auditory evoked potentials of the brain stem in brain injury. Prognostic value [I potenziali evocati uditivi del tronco encefalico nel cranioleso. Valore prognostico]

The study of brain stem auditory way in severe head trauma patients with auditory evoked potentials is very important for giving elements about functional and anatomic situation of analyzed neuronal substratum; ABR will be normal or altered in conformity with the level and/or the gravity of the damage. Authors have examined 20 post-traumatic comatose patients pointing out the existence of a strict relation between auditory brain stem responses and prognosis. Authors, in accordance with the ample literature in existence, agree to point out the auditory brain stem responses such as a very effective instrument for the prognostic valuation of post-traumatic comatose patients.
