Summary

The abnormal electroencephalogram (EEG) that attracts the most attention is that showing a seizure. In the intensive care unit (ICU), EEG monitoring is most commonly used for seizure detection; however, EEG can provide additional useful information. The background pattern can be used to evaluate encephalopathy and to assess cerebral function in patients who are sedated and paralyzed. EEG background can inform prognostication after hypoxic ischemic injury. EEG can serve as an ancillary investigation in the determination of brain death. Finally, EEG changes guide titration of treatments, such as continuous infusions administered for status epilepticus or increased intracranial pressure. Quantitative EEG (QEEG) is increasingly used by bedside clinicians for rapid assessment of cerebral function and facilitation of rapid interventions for critically ill patients.
