Clinical Trial Summary

Defining the origin of a seizure remains a difficult diagnosis. The presence of witness is not systematic, the clinical examination can be little contributory, and the delay recommended by the FSN is often surpassed for the realization of Creatine kinase (4h). In the event of a suspected seizure, an initial blood test with Creatine kinase and Lactates is often done on admission of the patient in other words before the 4hours delay.

It seems interesting to harmonize the practices, to limit the patient wait in the emergencies for a deferred dosage of CK at 4 hours from the seizure and to identify an early biological marker.

Objectives:

To evaluate the value of blood CK and Lactate dosage in emergency procedures in the diagnosis of generalized seizures.


Description:

We propose to carry out a prospective, observational, monocentric study at the CHU of Clermont-Ferrand. This is a descriptive analysis of the kinetics of the Creatine kinase and Lactates rates collected at the admission of a patient consulting for strong suspicion of convulsive seizure, and at 4 hours from the generalized seizure.

A patient consulting the emergency department for suspected seizure will have an usual blood test at the admission in this context with notably ionogram, fasting glucose, venous gasometry. As the CHU purchased a venous and arterial gasometry reader for the emergency department, blood ionogram, Hb, lactates, HCO3-, pH are collected without delay.

The Creatine kinase dosage will be collected in the usual way as a "tube bottom".

As recommended by the French Society of Neurology, a new sample will be collected at 4 hours of seizure for a dosage of Creatine kinase. The determination of the lactates will be based on a "tube bottom".

It is the emergency practitioner who will decide whether or not to include the patient in the descriptive study, assisted by a standardized survey, enumerating the high probability of generalized seizure orientation characteristics (patient history, treatments including antiepileptics, anamnesis, witnesses presence, evocative clinic) The study only recruited cases of strong suspicion of generalized seizure, beginning less than 4 hours to compare the kinetics of Creatine kinase and Lactates at admission and 4 hours of the generalized seizure.
