Auditory brainstem response (ABR) was recorded in 41 full-term newborn infants with intracranial hemorrhages (ICH; 10 infants with and 31 infants without neurological sequela) and the data were compared with those obtained in normal full-term newborn infants as controls. The wave-I peak latency was significantly prolonged in the non-sequela group than in the control group and in the sequela group than in the non-sequela group. The wave-III and wave-V peak latencies were significantly prolonged in the ICH group (sequela and non-sequela groups) than in the control group but did not significantly differ between the sequela and non-sequela group. The wave I-V interpeak latency did not significantly differ among the three groups. Among 10 infants in the sequela group, 9 had a V/I amplitude ratio (the amplitude of wave-I divided by the amplitude of wave- V) of less than 1.0. This suggests that the V/I amplitude ratio is of prognostic value in ICH infants.
对41例患有颅内出血（ICH）的足月儿进行了听性脑干反应（ABR）记录（10例有神经后遗症，31例无神经后遗症），并将数据与作为对照的正常足月儿的数据进行比较。非后遗症组的波I峰潜伏期比对照组显著延长，后遗症组比非后遗症组显著延长。ICH组（后遗症组和非后遗症组）的波III和波V峰潜伏期比对照组显著延长，但后遗症组和非后遗症组之间无显著差异。三组之间的波I-V峰间潜伏期无显著差异。后遗症组的10例婴儿中，9例的V/I振幅比（波I的振幅除以波V的振幅）小于1.0。这表明V/I振幅比在ICH婴儿中具有预后价值。
