Developmental Change of Brainstem Auditory Evoked Potential in Neonates
Published Online: Jul 24, 2015
To observe the developmental maturation of brainstem auditory evoked potential(BAEP) for neonates by obtaining the normative data of each BAEP component in our own electrophysiological laboratory.
We reviewed 129 BAEP recordings in neonates ranging in gestational age from 33 weeks to 44 weeks. The BAEP recording were analyzed into latency(wave I,III,V), interpeak latency(I-III,III-V,I-V) and amplitude ratio(I/V) at 75dB sensation level clicks according to gestational age.
The latencies of each BAEP component decreased with maturation. Interpeak latency of waveI-V(central conduction time)also decreased with increasing age during 33-40 weeks of gestational age.
