NCT01980446

Brief Summary

Determination of vital and functional outcome in comatose survivors after cardiac arrest is principally based on the identification of predictors of non-awakening, using by clinical, biological and electrophysiological tools. In patients without presence of non-awakening predictors, it would be of interest to identify predictive criteria of awakening. The presence of mismatch negativity during the cortical auditory-evoked potential could contribute to further progress in neurological prognostication of these patients. However, at this time, its prognostic value has been insufficiently studied and the optimal time of realization remains unknown.

Study Arms (1)

1:Mismatch negativity

OTHER

Presence of the mismatch negativity during the cortical auditory-evoked potential would predict a favorable outcome in comatose survivors after cardiac arrest.

Procedure: Auditory-evoked potentials

Interventions

cortical auditory-evoked potentials are performed to all included patients at inclusion, at day 5 to day 10, day without sedation (up to 1 year), day of awakening

1:Mismatch negativity
