Abstract
The patient is a female of 17 years of age. She presented with consciousness disturbance as the chief complaint and was admitted to our hospital with the diagnosis of status epilepticus (SE); she was moved to ICU to receive a respiratory treatment on the 2nd hospital day. A close examination at the hospital revealed that the cause of SE was due to systemic lupus erythematosus (SLE). While treating the primary disease, antiepileptic drug treatment started in order to control SE was unsuccessful; therefore, general anesthesia was induced with intravenous anesthetics. Despite the induction of general anesthesia with intravenous anesthetics, it was difficult to control SE, so inhalation anesthetic agent isoflurane was added from the 10th hospital day, which brought a success in controlling SE. The duration of the use of isoflurane continued for 38 days, but a long-term management was possible because there was no serious complication due to isoflurane was observed during the course of the treatment. Adding inhalation anesthetic agents can be considered as one of the options in the case where controlling SE is difficult through general anesthesia with intravenous anesthetic agents.
