The Transudate


The transudate is a fluid that accumulates in the serous cavities of the body due to the violation of blood and lymph circulation (with an increase in the permeability of blood vessels ). So, for example, with venous congestion caused by heart failure, the transudate appears in the cavities of the pleura , pericardium, in the abdominal cavity; circulatory disorders in the portal vein system (with cirrhosis of the liver) are accompanied by the occurrence of ascites (see). Transudate is transparent, usually colorless (if there is no admixture of blood or bile pigments), contains up to 2-3% protein, salt, in the centrifuge almost no cellular elements.

Unlike exudate (see), the transudate is not accompanied by inflammatory changes in serous membranes, pain, or temperature reaction, but can be infected and then complicated by the development of pleurisy , peritonitis .
