[Electroencephalographic silence after intoxication with a carbamate tranquilizer].

Abstract

A case of acute meprobamate poisoning in a 43 year-old-woman is reported. Twenty five hours after admission in the intensive care unit, deep coma and cerebral electrical silence were observed whereas the meprobamate plasmatic concentration was 250 mg/l. The patient recovery was uneventful. Meprobamate analysis must be performed for unexplained coma with isoelectric EEG.
