Electroencephalography (EEG) is an important and relatively inexpensive tool that allows intensivists to monitor cerebral activity of critically ill patients in real time. Seizure detection in patients with and without acute brain injury is the primary reason to obtain an EEG in the Intensive Care Unit (ICU). In response to the increased demand of EEG, advances in quantitative EEG (qEEG) created an approach to review large amounts of data instantly. Finally, rapid response EEG is now available to reduce the time to detect electrographic seizures in limited-resource settings. This review article provides a concise overview of the technical aspects of EEG monitoring for seizures, clinical indications for EEG, the various available modalities of EEG, common and challenging EEG patterns, and barriers to EEG monitoring in the ICU.

Purpose of reviewThe purpose of this review is to provide a succinct evaluation of the current rescue medications and action plans available to our patients with seizure clusters in the outpatient setting.Recent findingsThe main themes of the recent findings are that rescue medications and seizure action plans (SAPs) are underutilized, particularly in the adult population. The safety and efficacy of intranasal midazolam and intranasal diazepam is comparable with rectal diazepam for the treatment of seizure clusters. Additionally, this intranasal formulation has the benefit of a more socially acceptable route of administration and ease of use.SummaryThe implication of these findings is a greater variety and awareness in the rescue medications available to our patients suffering from seizure clusters.
