Abstract

A study was conducted in very-low-birth-weight (VLBW) neonates to correlate structural damage to the central nervous system due to intracranial hemorrhage (ICH) with electrophysiological function of the lower auditory system as measured by brainstem auditory evoked potentials (BAEP). BAEP testing of 61 VLBW neonates was completed at 36 weeks conceptional age. BAEP Wave III and V latencies significantly increased with increasing severity of ICH. Although significant at conventional levels (P < 0.05), these correlations were of modest size. Furthermore, after adjusting for the effects of birthweight, hypoxia, lowest pH and associated pCO2 the correlation between ICH and BAEP was reduced in magnitude and no longer significant. Thus, there is little evidence that ICH shortly after birth affected functioning of the auditory brainstem pathways in VLBW neonates at 36 weeks conceptional age.
