[Management of adult refractory convulsive status epilepticus in the intensive care unit]

Patients with convulsive status epilepticus in whom first line treatment is not rapidly effective, or with a persistent delay in recovering consciousness must be admitted in an ICU even if assisted, mechanical ventilation is not performed. Continuous EEG monitoring performed in close collaboration with a neurophysiologist/epileptologist is mandatory to detect and treat subtle status epilepticus and to exclude post-anoxic encephalopathy. A number of drugs and anaesthetic agents have been proposed to control refractory status epilepticus. Midazolam and/or propofol have been recently recommended before performing general barbiturate anaesthesia. However, this approach is not rigorously assessed, because patients and series are heterogeneous, and controlled studies are difficult to design. Prognosis is closely related to the quality of initial management, to the development of subtle status epilepticus and, above all, to aetiology.
