Alterations in the Intraventricular Pressure in Cats After Cold Induced Edema

Abstract

The experiments were set up in order to register the alterations in the intraventricular pressure in cats during the development of brain edema resulting from a cortical lesion cold-induced by Klatzo’s method. With the aid of a cooling thermoprobe which was put on the intact dura of the left frontal lobe, a decrease of temperature to -30°C was achieved. In contrast with other investigators we left the cooling thermoprobe in its place during the entire course of the experiment so as not to influence the intracranial pressure relations by decompression. The pressure was measured in the cella media of the right lateral ventricle, in which a needle was introduced by stereotactic means (Fig. 1).
