How do you differentiate a transudative from an exudative pleural effusion?
If pleural fluid protein is less tha 25g/l than it is transudate. And if pleural fluid protein More than 35g / l than it is exudate
Transudate Pleural Effusion: - The pressure in capillary is high which pushes the fluid through capillary. - The color of filtrate is pale yellow or clear. - The protein and cell content is very low. - Occurs due to high hydrostatic pressure or low capillary oncotic pressure. - Common causes are congestive heart failure, nephrotic syndrome, liver cirrhosis and chronic kidney disease. Exudate Pleural Effusion: - Fluid leaks from capillaries in inflammation. - The color of filtrate is bloody and cloudy. - Occurs due to increase in the permeability of capillaries. - Common causes are infection, pulmonary embolism, malignancy, and auto-immune disorders.
