Abstract
Nonconvulsive seizures are clinically important in severe traumatic brain injury but are difficult to detect when continuous electroencephalography (EEG) is not feasible in the intensive care unit. We conducted a prospective observational study to evaluate a nurse-led patch-type EEG protocol, with arterial spin labeling (ASL) magnetic resonance imaging as an exploratory comparator. Patch-type EEG monitoring was feasible in 21 of 24 enrolled patients (87.5%), and both EEG and ASL assessments were evaluable in 16 patients. Electrographic seizures were detected in four patients (25%), with all of them showing corresponding focal hyperperfusion on imaging. These findings suggest that simplified patch-type EEG monitoring is feasible in this setting; however, further studies are warranted to determine the clinical relevance of nurse-led patch-type EEG monitoring.
