Study information

Primary study designInterventional
Study designMulticentre, randomised, active controlled, parallel group trial
Secondary study designRandomised controlled trial
Scientific title
Study acronymSuSeQue (subclinical seizure question)
Study objectivesWe hypothesise that without continuous Electroencephalogram (EEG) registration, subclinical electrographic seizures will be missed. Repetitive ictal seizures and a subclinical status epilepticus may be deleterious to the immature brain. On the other hand the use of antiepileptic drugs may also have adverse effects, especially to the developing brain.
Ethics approval(s)Ethics approval received from the local medical ethics committee
Health condition(s) or problem(s) studiedNeonatal seizures
InterventionFollowing initiation of aEEG registration and the occurrence of the first subclinical seizure, and following parental consent, the infant will be randomised to:
1. Group A: treatment of clinical as well subclinical seizures as detected on the aEEG
2. Group B: the aEEG will be blinded, and only clinical seizures will be treated. Intermittent standard EEG can be performed and in case the EEG shows a status epilepticus this can be treated, but in case a subclinical seizure is seen on the standard EEG, this will not be treated with anti-epileptic drugs
Intervention typeOther
Primary outcome measure(s)

1. What is the number of electrographic seizure discharges missed if you do not monitor continuously
2. Does instantaneous treatment of electrographical seizures lead to:
2.1. A reduction of seizure discharges
2.2. Less damage on the neonatal Magnetic Resonance Imaging (MRI)

Key secondary outcome measure(s)

Does treatment of neonatal seizures lead to a reduced risk of Post-Neonatal Epilepsy (PNE) and an improved neurodevelopmental outcome at 24 months.
