Abstract
OBJECTIVE To investigate the accuracy of amplitude-integrated electroencephalography (aEEG) in detecting full-term neonatal seizures. METHODS Conventional EEG (cEEG) and aEEG were simultaneously applied to 62 full-term newborns with seizures and results were analyzed with different methods. RESULTS Of 876 seizures confirmed by cEEG, 21% were detected by clinical observation, 44.4% by aEEG and 85.7% by aEEG plus C3/C4 raw EEG. Of 531 seizures with a frequency higher than 5 times/h, 52.5% were detected by aEEG and 96.8% by aEEG plus C3/C4 raw EEG. Of 510 seizures lasting longer than 60 s, 50.6% were diagnosed by aEEG and 84.1% by aEEG plus C3/C4 raw EEG. Of 509 seizures originating in the central region, 57.9% were detected by aEEG and 90.9% by aEEG plus C3/C4 raw EEG. CONCLUSION Combination of aEEG with cEEG offers more accurate diagnosis, especially for detecting high-frequency, long-lasting and central region-generated seizures.
