Abstract:
Continuous neonatal brain monitoring using aEEG depends strongly on electrode performance. Existing electrodes may suffer from adhesion problems, impedance instability, and signal degradation during prolonged recordings. This study evaluates a novel neonatal electrode (aCUPE) specifically designed for long-term aEEG monitoring. Twenty newborns underwent simultaneous recordings using commercial and aCUP-E electrodes. Compared with commercial electrodes, aCUP-E achieved 86.2% versus 65.3% optimal recording time, demonstrated improved survival over 24 h, lower impedance variability, and comparable signal acquisition according to Bland-Altman analysis. These findings support that new electrodes such the aCUP-E could improve and broden the use of aEEG as a reliable tool for prolonged neonatal neuromonitoring.
