Emergency ("stat") EEG in the era of nonconvulsive status epilepticus

The most widely accepted indication for a stat EEG (stEEG) is the suspicion of nonconvulsive status epilepticus (NCSE). NCSE has been reported with surprising frequency in a wide variety of acute structural and metabolic brain injuries and significantly increases the risk of permanent brain damage and death. This risk rises and the effectiveness of treatment decreases with delays in diagnosis and increased duration of NCSE. Recent evidence confirms that more than half of NCSE patients improve with anti-seizure treatment. The emergence of NCSE as a common, dangerous, time-urgent, and treatable problem has positioned it as a target for emergency therapeutic intervention. NCSE can only be diagnosed by EEG testing, and stEEG has demonstrated value in improving NCSE management. As a result, in the near future, EEG laboratories will see increasing demands for stEEG related to NCSE. The two main obstacles to an effective stEEG program are EEG technologist coverage and electroencephalographer availability after work hours. We recommend three simple but fundamental changes in the traditional approach to stEEGs in order to overcome these obstacles: the use of EEG set-up templates by onsite personnel, easy access to EEG instruments after hours, and remote stEEG connectivity for real-time, off-site electroencephalographer interpretation.
