  • Limitations of single-channel EEG on the forehead for neonatal seizure detection JOURNAL OF PERINATOLOGY Wusthoff, C. J., Shellhaas, R. A., Clancy, R. R. 2009; 29 (3): 237-242

    Abstract:

    In amplitude-integrated EEG, lead placement across the forehead is convenient, but this location has unknown effects on neonatal seizure (NS) detection sensitivity. This study describes the limits of NS detection by a single forehead EEG channel.Records were taken from a digital library of conventional EEGs (CEEGs) with NS, previously characterized at a bicentral channel, C(3) --> C(4). We analyzed electrographic characteristics in a single forehead channel, Fp(3) --> Fp(4).A total of 330 seizures from 125 CEEGs were included. With Fp(3) --> Fp(4), at least one NS was detected in 66% of records vs 90% using C(3) --> C(4) (P<0.0001). Of 330 seizures, 46% appeared in Fp(3) --> Fp(4) vs 73% in C(3) --> C(4) (P<0.0001). Seizures appeared briefer in Fp(3) --> Fp(4) than C(3) --> C(4) (P<0.006) and CEEG (P<0.0001).NSs are significantly more difficult to detect with a single forehead channel than bicentrally or on CEEG. In Fp(3) --> Fp(4), a third of records with seizures were missed and over half of seizures were undetected.
