The importance of neonatal bifrontal EEG recordings which were easily obtainable during intensive care was tested to improve the possibilities of computer-assisted analysis and to characterize cerebral cortical function of newborns-at-risk. The EEG was computerized by spectral analysis in 9 healthy term newborns and 6 term newborns-at-risk according to the age related patterns. Surprisingly, newborns-at-risk with good outcome show significant higher EEG spectral power than controls. But a secure monitoring is unpossible by bifrontal recordings alone. It was concluded that: 1. the bifrontal EEG recordings should be replaced by at least two interhemispheric recordings for neonatal cerebral monitoring, 2. the pattern-related analysis is necessary and 3. the discontinuous EEG is most suitable to characterize newborns-at-risk.
