Abstract
Forty low risk newborn infants were studied with conceptual ages between 28 and 42 weeks. They were distinguished from high risk infants on the basis of neonatal medical complications. Brainstem auditory evoked potentials (BAEP) were recorded from vertex-ipsilateral and contralateral ear reference sites. Monaural 70 dBHL rarefaction clicks were presented at a repetition rate of 11 per second. Both ears were tested. The peak and interpeak latencies of waves I, III and V were measured in term and preterm infants. These intervals were analyzed in relationship to conceptual age in order to assess the relative contributions of the peripheral and central portions of the auditory system to the process of infant development.
Since it is expected that BAEPs will have increasing diagnostic and prognostic significance for the neurologic and otologic outcome of newborns, a short term study of these responses in relationship to risk factors is underway in our laboratory. This data forms, in part, a basis for comparison of auditory brainstem function in low and high risk infants. (Supported by USPHS Grant NS15254).
