[Hemodynamic study of postural regulation in the dog treated or not treated with levomepromazine].
Analysis of hemodynamic parameters in untreated and treated dogs (levomepromazine 5 mg/kg i.v.) during supine and erect position showed, 1) that the regulation of cerebral blood flow remained in the anaesthetized (pentobarbital 25 mg/kg i.v.) dogs ; 2) that the sympathetic reaction induced different effects in various vascular regions ; 3) that levomepromazine induced an impairement of the mechanisms involved in the regulation of the encephalic irrigation.
