Isoflurane Anesthesia Therapy for Nonconvulsive Status Epilepticus Continuing after the Control of Convulsive Status Epilepticus: A case report / 대한마취과학회지

ABSTRACT

Nonconvulsive status epilepticus (NCSE) is defined as continuous or nearly continous electrographic seizure activity lasting at least 30 minutes without clinical signs of convulsive activity. The presence of NCSE after the control of clinical status epilepticus (SE) is a significant prognostic indicator of outcome for SE. We report a case of a 25 year-old male patient that had viral encephalitis and showed electrographic seizure on electroencephalography (EEG) that persisted after the control of convulsive status epilepticus. The patient was treated with isoflurane under general anesthesia for 5 days after the standard antiepileptic drugs failed. We discontinued the use of isoflurane after NCSE reached optimal burst suppression, as seen on EEG, and it was controlled well with antiepileptic drugs.
