Brain seizures after cardiac arrest: can early treatment save lives?
NCT ID NCT06549426
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This trial studies whether giving anti-seizure medication to comatose patients who have brain seizure activity after cardiac arrest can improve their recovery. Participants are randomly assigned to receive either standard care alone or standard care plus a stepwise anti-seizure treatment. The study measures functional recovery and healthcare costs to see if the treatment makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- anti-seizure medication and sedative agents
- What this could lead to
- If effective, this approach could improve functional recovery and quality of life for comatose patients after cardiac arrest.
- What could go wrong
- This is a mid-stage trial with 150 participants, so results may not apply broadly. Anti-seizure drugs can cause side effects like sedation or low blood pressure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Coma (Glasgow Coma Scale score ≤ 8) after out of hospital cardiac arrest and resuscitation 2. Age ≥ 18 years 3. Continuous EEG with at least eight electrodes started \< 24h after return of spontaneous circulation (ROSC) 4. ESE or possible ESE according to the Salzburg and ACNS criteria 5. Possibility to start treatment within three hours after detection of ESE Exclusion Criteria: 1. Known history of another medical condition with limited life expectancy (\< six months) 2. Any progressive brain illness, such as a brain tumor or neurodegenerative disease 3. Pre-admission Glasgow Outcome Scale score of 3 or lower 4. Reason other than the neurological condition to withdraw treatment 5. EEG background activity prior to the emergence of ESE indicative of extensive irreversible anoxic brain injury 6. Follow-up impossible due to logistic reasons, for example not living in the Netherlands or Belgium
