Eductional Objective: Status epilepticus is a single seizure lasting >5 minutes or the occurrence of multiple discrete seizures with incomplete recovery of consciousness between episodes. The initial treatment includes intravenous lorazepam and phenytoin given concurrently. Phenytoin is a long-acting anticonvulsant that inhibits neuronal high-frequency firing by reducing the ability of sodium channels to recover from inactivation
