Palliative Sedation for Status Epilepticus in a Patient with Progressive Multifocal Leukoencephalopathy

ABSTRACT

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. The patient was an HIV positive 29-year-old male who was suffering from progressive multifocal leukoencephalopathy complicated by a refractory status epilepticus and who was suspected of previous benzodiazepines and opioid abuse. In such situations of a suffering brain doses of midazolam to achieve symptom control may be much higher than expected.
