[Diagnostic value of the early auditory evoked potentials in acute cranio-cerebral trauma in children].

The brainstem auditory evoked potentials were recorded in 54 children within the first 48 hours after a head trauma of different degree. In comparison with an age--appropriate standard group there are changed BAEP in 51% of the examined children after head trauma. The abnormalities mainly consist in changes of the wave--morphology, the latencies of the waves 1, 3 and 5 were significantly prolonged. The interpeak--intervals only unessentially differ from the standard group. The detected BAEP--changes are of different kind and incidence. A typical change of the potential for the infantile head trauma cannot be found. The regression of the traumatically conditioned BAEP--changes begins during the first days after trauma and it is finished within 6 months in half of the children. In the particular case changes can be detected after two years yet.
