Brief summary
A large proportion of patients (up to 20%) who suffer from an epileptic seizure and remain unconscious suffer from a non-convulsive epileptic seizure. The condition is difficult to diagnose, and impossible without the required instruments. Electroencephalogram is required in the diagnosis of non-convulsive status epilepticus. Presently, the diagnostic value and implementation of such a device in the prehospital field is little studied. The aim of this study is to evaluate the diagnostic value of the acquired electroencephalogram with a prototype EEG/EKG adapter connected to a Physio-Control LifePak 15 defibrillator/monitor. The EEG is registered in a otherwise normal fashion with scalp-electrodes, but only three channels are monitored, as this is deemed sufficient for the prehospital field, as well as for monitoring the epileptic seizures.
Interventions
DEVICERegistration of EEG
EEG is registered for study purposes. No interventions to patient care is done at this stage. Acquisition is done without harming the patient.
