Anesthetic management for a patient with multiple sclerosis at exacerbation stage under general anesthesia

A 39-year-old woman with multiple sclerosis (MS) at exacerbation stage underwent dilatation and curettage. MS is characterized by chronic inflammation, demyelination, and gliosis in the central nervous system. Surgical stress often induces exacerbation of MS symptoms. Therefore, deep anesthesia is required for anesthetic management in cases of MS. We monitored electroencephalograph (EEG), spectral edge frequency 90 (SEF 90), spectral median frequency (SMF) and δ-amplitude for depth of anesthesia using pEEG™ (Dräger, Germany). In this case, anesthesia was induced with sevoflurane and gradually increased to 5% in oxygen 4 l · min^-1 and maintained with sevoflurane 2-3% in 2 nitrous oxide l · min^-1 and 2 l · min^-1 oxygen. Surgery was completed and no spike wave was observed by pEEG™ monitoring during surgery. In conclusion, sevoflurane anesthesia was useful for a patient with MS during exacerbation stage.
