Auditory brainstem response in NICU infants.

To assess the I-V interpeak latency (I-V IPL) as an index of neural development in a premature population, auditory brainstem response (ABR) performed on 145 ears of 89 neonatal intensive care unit (NICU) infants was analyzed. The obtained I-V IPLs were compared with conceptional age and risk factors such as neonatal asphyxia, respiratory distress, metabolic disorders, etc. Those infants who received phototherapy or aminoglycoside antibiotics had statistically significant prolongation of I-V IPL. Thus, measurement of I-V IPL might be a valuable monitor against risk factors.
