Palliative sedation for status epilepticus in a patient with progressive multifocal leukoencephalopathy.

Palliative sedation is defined as the use of sedative drugs in order to reduce the patient's consciousness in case of refractory symptoms. The most used drug is midazolam, a benzodiazepine with a short half-life administered either intravenously or subcutaneously. We discuss on a clinical case requiring an exceptionally high dosage of midazolam-up to 160 mg iv daily-to achieve palliative sedation.
