Cassette electroencephalography in the evaluation of neonatal seizures
S. L. Bridgers, J. S. Ebersole, L. R. Ment, R. A. Ehrenkranz and C. G. Silva
Three-channel cassette electroencephalographic (EEG) recording for up to 24
hours was obtained from 37 neonates with clinically diagnosed or suspected
seizures but no seizure activity on routine EEG. EEG seizures were recorded
in seven patients, five of whom had experienced clinical seizures in the 24
hours prior to cassette EEG recording. EEG seizures were detected in only
one of nine neonates with recurring clinical episodes believed unlikely to
be seizures and in only one of 18 without recent clinical events. Cassette
EEG can enhance the detection and differentiation of seizures in neonates
with persistent clinical episodes but is of low yield otherwise.
