[Auditory brain stem response in patients with consciousness disturbance].
To investigate the prognosis for patients with consciousness disturbance, we recorded auditory brain stem response (ABR) in 35 patients with primary or secondary brain damage. For patients with secondary brain damage, the first ABR recorded after admission could be used not only to differentiate consciousness level but also to predict prognosis. However, for the patients with primary brain damage, the first ABR could not be used for either differentiating consciousness level or predicting prognosis. In addition, in two patients with secondary brain damage, the series of ABR recordings indicated that brain stem damage was reversible.
