Abstract
We report the case of a 30-year-old woman with severe, prolonged refractory status epilepticus requiring more than 6 months of iatrogenic coma. Opinions on prognosis and clinical management were solicited from a number of experienced neurointensivists and epileptologists at multiple time-points during the clinical course. The ensuing discussion, annotated with references, is presented here. Several experts commented on isolated cases of young patients with encephalitis requiring up to 2–3 months of iatrogenic coma, yet still having good outcomes. Treatments discussed include ketamine, gammaglobulin, plasmapheresis, steroids, adrenocorticotropic hormone, very high-dose phenobarbital, isoflurane, lidocaine, electroconvulsive therapy, ketogenic diet, hypothermia, magnesium, transcranial magnetic stimulation, vagus nerve stimulation, deep brain stimulation, and neurosurgery. The patient eventually suffered a cardiac arrest but was resuscitated as requested by the family. Seizures then stopped, and the patient has remained in a persistent vegetative state since.
