Pleural Effusion Causes ,Classification,Symptoms and Treatment

Pleural effusion is the excess accumulation of fluid in the pleural cavity which can sometimes restrict lung expansion.

Lymphatic effusion( chylothorax) Transudative effusions are caused by some combination of increased hydrostatic pressure and decreased plasma oncotic pressure.. They are usually ultrafiltrates of plasma squeezed out of the pleura as a result of an imbalance in hydrostatic and oncotic forces in the chest.- Conditions associated with increased hydrostatic pressure include~heart failure and~liver cirrhosis with ascites.(low proteins) -The ones associated with hypoalbuminemia are usually nephrotic syndrome (protein loss) -Because these diseases are systemic, they usually cause bilateral and equal effusion. ~They are caused by local processes leading to increased capillary permeability due to inflammation.This results in exudation of fluid, protein, cells, and other serum constituents. ~An exudative effusion will cause unilateral effusions. The clinical manifestations of pleural effusion are variable and often are related to the underlying disease process. The most commonly associated symptoms are~cough~progressive dyspnea ~ DIB~pleuritic chest pain~ worse when lying flat Physical examination reveals~Absent tactile fremitus,~Dullness to percussion, and ~Decreased breath sounds on the side of the effusion. Pleural fluid analysisChest x-ray indicates tracheal deviation An erect chest x ray shows fluid accumulation at the costoprenic angle X ray taken when a patient is supine indicates layering effect ~Thoracenthesis is done to relieve the symptoms and also help in diagnosis. ~Transudative fluid is clear while exudative fluid looks cloudy due to presence of immune cells .~Lymphatic fluid looks milky because its filled with fats .~Exudative fluid has much more proteins than Transudative ~grossly bloody fluid indicates trauma To differentiate then you use the Light criteria The fluid is considered an exudate when: ~The ratio of pleural fluid to serum protein is greater than 0.5 ~Ratio of pleural fluid to serum LDH is greater than 0.6 ~Pleural fluid LDL or cholesterol is greater than 2/3 of the upper limits of normal serum value.If all these are absent the fluid is a transudate. ~RX involves removal of the fluid and treat the underlying cause ~PE from heart failure are treated with Diuretics and sodium restriction Show us your support by SUBSCRIBING,LIKING and SHARING.
