BAEP of Neonates with Hyperbilirubinemia
|
|
|
|

Abstract
|
|
|
The sequelae of neonatal hyperbilirubinemia include hearing loss as well as other central nervous system deficits. It is generally accepted that the most sensitive test for hearing loss in neonates is the brainstem auditory evoked
potential(BAEP).
The
purpose of this study is to demonstrate the changes of BAEP in neonatal hyperbilirubinemia in order to evaluate the cochlear damage and the prognostic value of brainstem lesion.
The waves of BAEP in 25 of 33 neonates were absent or prolongation of the latencies of wave I, the interpeak latencies of wave I-III and I-V, and the difference latency of wave I between Rt and Lt side were significant statistically. Our results
indicate latencies appear to be more sensitive than amplitudes of BAFP.
We may conclude that BAEP testing can be used to screen hyperbilirubinemic fullterm and premature infants for cochlear damage. The question of a safe level of bilirubin concentration, and safe duration of exposure relative to long-term minor or
soft
neurodevelopmental handicaps remains unanswered. Large, controlled, prospective, epidemiologic studies are needed to provide these answers.
