Summary

Endovascular thrombectomy (EVT) is the standard treatment for patients with a large vessel occlusion (LVO) stroke. Direct presentation of patients with an LVO to a comprehensive stroke center (CSC) reduces onset-to-treatment time by approximately an hour and thereby improves clinical outcome. However, a reliable tool for prehospital LVO-detection is currently not available. Previous electroencephalography (EEG) studies have shown that hemispheric hypoxia quickly results in slowing of the EEG-signal. Dry electrode EEG caps allow reliable EEG measurement in less than five minutes. We hypothesize that dry electrode EEG is an accurate and feasible diagnostic test for LVO in the prehospital setting.

ELECTRA-STROKE is a diagnostic pilot study that consists of four phases. In phases 1, 2 and 3, technical and logistical feasibility of performing dry electrode EEGs are tested in different in-hospital settings: the outpatient clinic (sample size: max. 20 patients), Neurology ward (sample size: max. 20 patients) and emergency room (sample size: max. 300 patients), respectively. In the final phase, ambulance paramedics will perform dry electrode EEGs in 386 patients with a suspected stroke. The aim of the ELECTRA-STROKE study is to determine the diagnostic accuracy of dry-electrode EEG for diagnosis of LVO-a stroke when performed by ambulance personnel in patients with a suspected AIS. Sample size calculation is based on an expected specificity of 70% and an incidence of LVO stroke of 5%.

Dry electrode EEG

A single dry electrode electroencephalography (EEG) will be performed in each patient that is included in this study. To do this, the investigators will use the WaveguardTM dry electrode EEG cap and compatible eegoTM amplifier, developed by ANT Neuro B.V. Netherlands and both CE marked as medical devices in the European Union (see appendices 1 and 2). Both products will be used within the intended use as described in the user manuals. The dry electrode cap is put on the patients head and records the EEG signal for several minutes; the amplifier is used to amplify the EEG signal and reduce artefacts.
