Effectiveness of Combined Levetiracetam and Midazolam in Generalized Convulsive Status Epilepticus in Children

Summary

Generalized status epilepticus is a common pediatric neurological emergency with significant mortality and morbidity. Benzodiazepines remain the first anticonvulsive line but benzo-diazepines don't control seizures in about 30% of cases. GCSE may be more rapidly stopped and controlled through combining another drug with benzodiazepines such as Levetiracetam, acting by different pathways. This study aims to evaluate the effectiveness of combined levetiracetam and midazolam in treatment of generalized convulsive status epilepticus in children.
