Summary

This chapter focuses on the variety of different EEG patterns that can be seen after hypoxic ischemic brain injury, which often produces some of the most severe encephalopathies. Common post–cardiac arrest findings include discontinuity, burst suppression, background voltage attenuation and suppression, lack of EEG reactivity, seizures, myoclonus, and status epilepticus. The prognostic significance of these findings is discussed. Finally, the topic of using EEG as a confirmatory tool in brain death protocols is introduced.
