[Experimental study of the sensitivity to catecholamines after lumbar sympathectomy (author's transl)].
To determine sensitivity to catecholamines after lumbar sympathectomy the authors first tested it in dogs : there was an increase in reactions to catecholamine beyond doubt after bilateral lumbar sympathectomy. In patients with arteritis they recorded, on a segment of the lower limb, a rheographic tracing with simultaneous modifications of the arterial blood pressure and electrocardiogram. These were studied after injection of adrenalin or noradrenalin in a dose of 5 to 7.5 mug (physiologic or stress level). Each of these tests were performed before and after lumbar sympathectomy.
