Potenciales evocados auditivos de tallo cerebral en niños lactantes de término con antecedente de encefalopatía hipóxico-isquémica neonatal

Objective: this study was designed to characterize the differences between normal children and those with neonatal encephalopathy, regarding the brain auditory evoked potentials (BAEPs), these differences may be which may be used as an exploratory guide of the brain stem condition. Methods. A sample of 34 infants suffering from neonatal encephalopathy (NE) and 34 healthy children were studied. Using the BAEP technique, the latencies and amplitudes of the waves I, II, III, and V, were measured, as well as the intervals I-III, III-V, and I-V. The differences between groups were evaluated through a analysis of variance and a conglomerate analysis. Results: the latencies of the waves I, II, and V, were more prolonged in the group of children with NE than in the group of healthy children, and the amplitudes of the NE group were larger than controls. The intervals I-III and I-V and waves III and V, were also different in both groups. The conglomerate
