Status epilepticus is the leading neurological emergency in children, with mortality 2-7% and significant morbidity (10-20%). It is defined as the occurrence of a crisis lasting more than 5 minutes and requiring the implementation of treatment to stop it and thus limit the immediate and long-term consequences.

The research hypothesis is that LEVETIRACETAM is non-inferior to PHENYTOIN in terms of cessation and absence of recurrence of status epilepticus, with better clinical tolerance in children from 3 months to 17 years old, with or without epileptic disease, with or without a history of status epilepticus
