Exudative pleurisy refers to a disease in which infection and other factors lead to inflammatory response of the pleura followed by inflammatory exudation, which in turn produces pleural effusion.
Infection of the pleura by pathogenic microorganisms such as bacteria and viruses causes an inflammatory reaction in the pleura, with a large number of inflammatory cells infiltrating the pleura, an increase in the permeability of the pleural capillaries, etc., and obstruction of the pleural lymphatic reflux. As a result, the water in the pleural vessels leaks out through the vessel wall into the pleural cavity, producing an inflammatory effusion with a yellow turbid appearance, often accompanied by clots. Laboratory findings include leukocytosis, decreased pH, and increased protein content.
Exudative pleurisy usually has chest pain, dyspnea, cough, chest tightness, fever, chills, etc. At the onset of the disease, attention should be paid to rest, high-protein diet, and usually pay attention to active exercise to improve the body’s immunity.
