[Changes in electrolyte homeostasis in acute loading of the right heart].

The authors carried out experimental studies on electrolyte homeostatis of healty cats and of cats with experimental stenosis of the lung artery after venous infusion of the dextran plasma substitute Reoisodex. There was a statistically significant reduction only of the level of ionized calcium under the influence of the infusion. The authors established an increase of the level of inorganic phosphorus and of the serum bicarbonates in animals with experimental stenosis of the lung artery.
