[Prognostic predictive value of neonatal ultrasonic studies of the CNS and of EEG monitoring for the psychomotor development at 1 year of age].

The prognostic value of cranial ultrasound and EEG-monitoring for the developmental outcome at 1 year of age in 209 premature and full-term newborns was studied retrospectively. The first ultrasound examination was performed within the first three days of life. Further investigations were done depending on type of severity of the findings. The investigation was completed by EEG-monitoring in 41 patients. The infants were investigated for psychomotor development. 158 infants were found normally developed. Abnormal neonatal ultrasound findings were registered in 18.9% of them. Developmental retardation was observed in 46 infants. 54.3% of them had abnormal ultrasound findings. 2/3 of infants with neonatal major brain insults like IVH III-IV or leukomalacia showed serious neurological handicaps, whereas subependymal bleedings seem to be without influence onto the development. In contrast pathologic EEG's were of higher prognostic value. None of the infants with a abnormal EEG was developed normally.
