Brief Summary
The goal of this comparative effectiveness trial is to study electrographic status epilepticus (ESE) treatment in comatose patients after cardiac arrest. The main questions the trial aims to answer are:
- Does ESE treatment improve outcome?
- What is the impact of ESE treatment on healthcare costs? Participants in the the intervention group will receive standard care completed with anti-seizure treatment. The control group will receive standard care without anti-seizure treatment.

Outcome Measures
Primary Outcomes (1)
score on the extended Glasgow Outcome Scale (eGOS)
eGOS is an 8-points ordinal scale of functional recovery with possible scores ranging from 0 to 6. A higher score indicates better functional recovery
6 months after cardiac arrest
Secondary Outcomes (1)
quality adjusted life years (QALYs)
12 months after cardiac arrest
Other Outcomes (5)
survival in months
12 months after cardiac arrest
death (any cause), pneumonia, sepsis (according to sepsis 3 criteria), bleeding (any cause), cardiac arrhythmia (any associated with hemodynamic compromise), new cardiac arrest, or thrombopenia
12 months after cardiac arrest
score on the Rankin Scale (mRS)
6 and 12 months after cardiac arrest
- +2 more other outcomes
Study Arms (2)
Intervention group
OTHERStandard care completed with stepwise anti-seizure treatment according to protocols for clinically overt status epilepticus. This consists of a stepwise approach consisting of 3 potential steps. Each next step will be taken as soon as possible (within 30 minutes of ESE first diagnosis or recurrence) if the previous step was insufficiently effective to sustainably suppress ESE.
Control group
NO INTERVENTIONStandard care without anti-seizure treatment.
Interventions
Stepwise approach: 1. a single dose of a parenteral benzodiazepine (lorazepam, midazolam, or diazepam) and a first parenteral anti-seizure medication (levetiracetam, valproate, or lacosamide) 2. a second parenteral anti-seizure medication plus a first continuous parenteral sedative agent (midazolam or propofol) 3. a second continuous parenteral sedative agent (midazolam, propofol, or ketamine)
Eligibility Criteria
You may qualify if:
- Coma (Glasgow Coma Scale score ≤ 8) after out of hospital cardiac arrest and resuscitation
- Age ≥ 18 years
- Continuous EEG with at least eight electrodes started \< 24h after return of spontaneous circulation (ROSC)
- ESE or possible ESE according to the Salzburg and ACNS criteria
- Possibility to start treatment within three hours after detection of ESE
You may not qualify if:
- Known history of another medical condition with limited life expectancy (\< six months)
- Any progressive brain illness, such as a brain tumor or neurodegenerative disease
- Pre-admission Glasgow Outcome Scale score of 3 or lower
- Reason other than the neurological condition to withdraw treatment
- EEG background activity prior to the emergence of ESE indicative of extensive irreversible anoxic brain injury
- Follow-up impossible due to logistic reasons, for example not living in the Netherlands or Belgium
