Auditory brainstem responses as a clinical evaluation tool in children after perinatal encephalopathy

Abstract:

Auditory brainstem responses (ABR) reveals the neurophysiological status of the neural axis. In this study we compared the ABR of healthy children, under 1-year-old, with children who suffered from perinatal encephalopathy (PE). OBJECTIVE: The purpose of this study was to characterize the ABR differences between children with PE and healthy children in order to identify groups with specific neurophysiological profiles, associated with their neurological condition. METHODS: Thirty-six children with perinatal encephalopathy (PE) and 36 healthy children, ages 1–12 months, were studied. The variables considered were: latencies of waves I, II, N1, III, V, and N2; interpeak latency interval (IPL) of waves I–III, III–V, and I–V; as well as amplitudes of waves I, III, and V. The results were analyzed using ANOVA, as well as Ji2, and Ward's cluster analysis. RESULTS: The absolute latencies of the ABR showed an inverse …
