Status Epilepticus.

Status epilepticus is a neurologic emergency defined as a seizure that lasts longer than 5 minutes. This is the most common neurologic emergency in children, and it is associated with significant morbidity and mortality. Initial seizure management focuses on stabilization of the patient, followed by medication to terminate the seizure. Benzodiazepines, levetiracetam, fosphenytoin, valproic acid and other antiseizure medications can effectively halt status epilepticus. There is a narrow but important differential diagnosis, including prolonged psychogenic nonepileptic seizure, status dystonicus, and nonconvulsive status epilepticus. Focused laboratory testing, neuroimaging, and electroencephalography can be useful in the evaluation of status epilepticus. Sequelae include focal neurologic deficits, cognitive impairment, and behavioral problems. Pediatricians play an important role in the early recognition and treatment of status epilepticus, thereby preventing the acute and chronic harm that can be associated with status epilepticus.
