Auditory brainstem evoked response inter-peak latencies in very low birthweight infants.

A population of very low birthweight (VLBW) infants consisting of 41 infants (24 female) less than 1000 g birthweight and 108 infants (63 female) 1000-1499 g together with a normative group of 36 full-term infants (18 female) 2400-4500 g birthweight were used to acquire auditory brainstem evoked response data. Inter-peak latency intervals were derived from the response and the data acquired were analysed across a range of related variables. The Wave V-III peak to peak latency interval was found to have significant age-related attributes together with an interactive birthweight effect, however no significant difference was established between the VLBW and normative groups when an age correction factor was applied.
