status epilepticus, a medical emergency characterized by continuous seizures lasting more than 30 minutes without interruption. Status epilepticus can be precipitated by the sudden withdrawal of anticonvulsant drugs, inadequate body levels of glucose, a brain tumor, a head injury, a high fever, or poisoning. Therapy includes IV administration of anticonvulsant drugs, nutrients, and electrolytes. An adequate airway is usually maintained with a nasopharyngeal or endotracheal tube.
