Abstract

OBJECTIVES
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.
METHODS
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.
RESULTS
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.
CONCLUSION
These results provided the concept of abnormal in neonatal BAEPs and opportunity of functional evaluation about the auditory or brainstem maturation in pathologic conditions.
