Peri- and intraoperative EEG signatures in newborns and infants

OBJECTIVE The electroencephalographic derived indices have been developed for adult patients, however these monitors have not been validated for infants. METHODS Frontal EEGs were recorded in 115 infants aged  6-months have a strong reduction of relative δ-power from baseline to the intraoperative situation, which corresponds to an increase of faster frequencies. CONCLUSIONS Age dependent perioperative EEG signatures can be demonstrated in infants younger than one year. SIGNIFICANCE We demonstrate significant differences in EEG readouts between newborns and infants which questions our monitoring systems in paediatric anaesthesia.
