title: [Auditory brainstem evoked potentials in hearing loss after bacterial meningitis].
abstract: Fourteen children with acute bacterial meningitis, were examined for auditory brainstem evoked potentials (ABEP) during their initial hospital course (days 3 to 24 from admission). Different degrees of neurosensory hypoacusia were detected in 8 patients (57.14%). Children aged less than one year seemed to be more susceptible to auditory deficit. In 6 children a second ABEP was done after a time interval which ranged from 20 to 570 days after the first one and all them showed residual hypoacusia. The short term evolution suggests that the acute process can be prolonged for more than 1 month after hospital admittance, and the altered auditory function tends to persist over the mid term. It is concluded that despite this research's methodological limitations. ABEP seem useful for early detection of postmeningitical neurosensory hypoacusia and follow-up of these patients.
