Aim:  To examine brainstem auditory function at term in late preterm infants admitted to neonatal intensive care unit (NICU). Methods:  52 preterm infants, born at 33-36 week gestation, were recruited in an NICU, and studied at term using brainstem auditory evoked response (BAER). Results:  Compared to normal term infants, BAER wave V latency in the NICU preterm infants was increased at 51 and 91/s (p <0.05, 0.05). III-V and I-V intervals were increased at all 21, 51 and 91/s clicks (p <0.05-0.01), which was more significant at higher than lower rates. III-V/I-III interval ratio was increased significantly at 51 and 91/s (p <0.05 and 0.01). Wave I and III latencies and I-III interval did not differ significantly from normal controls at any click rates. All amplitudes of waves I, III and V amplitude tended to be reduced at higher rates, while wave I amplitude was reduced significantly at 91/s clicks. Conclusion:  There were BAER abnormalities in the NICU late preterm infants, suggesting compromised brainstem auditory function. Compared to a basically normal BAER in low-risk late preterm infants previously reported, the abnormalities suggest that perinatal problems or complications adversely affect the late preterm auditory brainstem.
