Convulsive status epilepticus

Also written as: CSE — convulsive status epilepticus

A medical emergency involving continuous convulsive seizure activity lasting 30 minutes or longer, or recurrent seizures without recovery of consciousness.

Full Definition

Convulsive status epilepticus (CSE) is a life-threatening neurological emergency characterized by prolonged or repetitive generalized tonic-clonic seizures without recovery of consciousness between episodes. The traditional definition requires seizure duration of 30 minutes, but current clinical practice often initiates emergency treatment after 5-10 minutes due to the risk of permanent neurological damage. CSE can result from various causes including medication withdrawal, metabolic disturbances, infections, or acute brain injury. Treatment follows established protocols involving sequential administration of benzodiazepines, antiepileptic drugs, and potentially anesthetic agents. Prompt recognition and treatment are crucial to prevent morbidity and mortality associated with hyperthermia, rhabdomyolysis, and neuronal injury.

Usage

Usage note: Distinguish clearly from non-convulsive status epilepticus in medical documentation.
