A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
The pleural fluid is most often straw-colored, and it has a distinct smell like ammonia. The fluid usually has a nucleated cell count between 50 and 1500 per cm 3. [4] The pH of the fluid is usually between 5 and 7. [9] Primary factors for diagnosing urinothorax by pleural fluid include low protein and high lactate dehydrogenase content. [10]
Hydrothorax is the synonym of pleural effusion in which fluid accumulates in the pleural cavity. This condition is most likely to develop secondary to congestive heart failure, following an increase in hydrostatic pressure within the lungs. More rarely, hydrothorax can develop in 10% of patients with ascites which is called hepatic hydrothorax ...
A pleural effusion is sometimes present that is exudative (fluid that leaks out of blood vessels). [21] This is detectable by decreased percussion note, audible breath sounds, and vocal resonance. Strain on the right ventricle may be detected as a left parasternal heave, a loud pulmonary component of the second heart sound , and/or raised ...
Thoracentesis / ˌ θ ɔː r ə s ɪ n ˈ t iː s ɪ s /, also known as thoracocentesis (from Greek θώραξ (thōrax, GEN thōrakos) 'chest, thorax' and κέντησις (kentēsis) 'pricking, puncture'), pleural tap, needle thoracostomy, or needle decompression (often used term), is an invasive medical procedure to remove fluid or air from the pleural space for diagnostic or therapeutic ...
Pleural empyema is a collection of pus in the pleural cavity caused by microorganisms, usually bacteria. [1] Often it happens in the context of a pneumonia, injury, or chest surgery. [1] It is one of the various kinds of pleural effusion.
The 4-year-old dog was taken to a pet hospital last week, where he was treated for a high fever and pleural effusion, a condition where excess fluid accumulates between the lungs and the chest wall.
In some cases of pleural effusion, the excess fluid becomes infected and turns into an abscess. This is called an empyema. Pleural effusion involving fibrinous exudates in the fluid may be called fibrinous pleurisy, which sometimes occurs as a later stage of pleurisy. A person can develop a pleural effusion in the absence of pleurisy.
