Abstract
Summary
Blood cell counts were compared in samples drawn simultaneously from the aorta, right ventricle, superior vena cava, caudal vena cava, hepatic vein, and/or peripheral veins in dogs. The study was done on normal and splenectomized dogs, either un-anesthetized or anesthetized with pentobarbital. No differences in erythrocyte or leukocyte distributions were demonstrated as a result of anesthetization or splenectomy. The erythrocyte and leukocyte counts were the same in arterial and venous blood samples and in venous samples from different major vessels. Some factors are discussed which may be responsible for apparently contradictory reports concerning cell count distribution in circulating blood.
