Amplitude reduction in brainstem auditory response in term infants under neonatal intensive care

► Perinatal hypoxia-ischemia is known to depress neonatal brainstem auditory electrophysiology, but it remains to be investigated whether perinatal conditions other than hypoxia-ischemia depress the electrophysiology in term neonates under intensive care. ► The amplitudes of wave components in maximum length sequence brainstem auditory evoked response were reduced in our term neonates under intensive care due to perinatal conditions other than hypoxia-ischemia. ► Brainstem auditory electrophysiology is depressed in term neonates under intensive care, possibly due to collective adverse effects of perinatal conditions.
