[Coma with bilateral mydriasis after use of transdermal scopolamine in ICU].

We report the case of an ICU patient with previous medical history of head trauma with hydrocephalus requiring ventricular derivation, presenting a coma (Glasgow Coma Score=8) with bilateral mydriasis after the use of transdermal scopolamine (1 mg) for profuse bronchial secretions. Neurological explorations (CT-scan and electroencephalogram) confirmed the absence of organic cause to the neurological deterioration. Neurological status rapidly and completely improved after removal of transdermal scopolamine suggesting a central anticholinergic syndrome.
