title: [Evoked response audiometry in newborn infants examined earlier by fetal audiometry].
abstract: The aim of this study was to investigate the influence of acoustic stimulus on behavioural heart responses of fetuses near term (38 to 42 weeks of gestational age) and comparison assessment of FHR to Auditory Brain Stem Responses (ABR) in the same babies after their birth. The study group consisted of 30 babies with pathological pregnancies and control group of 30 neonates of physiological pregnancies. Our results indicated, that the pattern of FHR accelerations after application of acoustic stimulus was significantly altered and depended on of the kind of pregnancy. Duration and amplitude of FHR obtained in the patients with complicated pregnancy were significantly smaller in comparison to the pattern observed in normal patients (142 msec to 249 msec, and 36 to 22 as well). Comparing the results obtained in FA (Fetal Audiometry) and ABR (Auditory Brain Stem Responses) we can say, that prolonged latency between a stimulus and accelerations is also combined with the prolonged latency of consecutive waves in ABR. Shortened duration of accelerations and its decreased amplitude could respond to the diminished amplitude in ABR recordings.
