The normal pleural space contains a rela-tively small amount of fluid, 0.1 to 0.2 mL/kg of body weight on each side.1,2 Pleural fluid is formed and removed slow-ly, at an equivalent rate, and has a lower pro-tein concentration than lung and peripheral lymph. It can accumulate by one or more of the following mechanisms1–3: • Increased hydrostatic pressure in the microvascular circulation: clinical data …, n a normal pleural space, fluid enters and exits at a constant, equal rate because of the ongoing filtration of a small amount of low-protein liquid in normal microvessels. Near the end of the 19th century, Starling and Tubby 1 hypothesized that the exchange of microvas - cular fluid and solutes was governed by the balance between hydrostatic.

Pleural Fluid Analysis and Radiographic Sonographic and. Pleural effusion is a buildup of fluid in the chest cavity, between the layers of tissue that cover the chest cavity and the outside of each lung (pleurae). Pleural fluid analysis is a group of tests used to diagnose the cause of the fluid buildup, such as congestive heart failure, cirrhosis, infection, cancer or autoimmune disorders., Pleural effusions commonly occur in patients under the care of all specialties of medicine and surgery. The incidence of pleural effusions in the United States is estimated to be at least 1.5 million annually. 1 Thoracentesis, a relatively simple diagnostic procedure, can be performed in the office, at the bedside, in the intensive care unit, and in dedicated procedural suites. Pleural fluid analysis in isolation will result ….

Differential Diagnosis of Pleural Effusions normal pleural membrane, vascular wall, and lymphatic vessel structure. For example, in some cases pleural fluid accumulates as a result of an increase in fluid production due to increases in hydrostatic pressure, reductions in oncotic pres-sure, or reductions in absorption. By contrast, an exudate results from fluid that accumulates in the pleural cavity as a … 01-08-2011 · Materials and Methods. Pleural fluid analysis with clinical, laboratory, radiographic, sonographic, and echocardiographic data of 975 consecutive, ultrasound-guided thoracenteses performed between January 2001 and December 2008 by the Pleural Procedure Service at the Medical University of South Carolina were reviewed.

Because the lung cannot expand, the pleural pressure becomes more negative than normal, increasing transudation of fluid from parietal pleural capillaries. The fluid characteristically is borderline between a transudate and an exudate; ie, the biochemical values are within 15% of the cutoff levels for Light’s criteria (see table Criteria for Identifying Exudative Pleural Effusions ). 01-04-2012 · A basic biochemical exploration of an MM-associated pleural effusion should include protein electrophoretic analysis of the serum and pleural fluid, combined with an anatomic pathology study. A significant decrease in the serum or pleural fluid concentration of γ globulin should be followed with a free light chain assay.

Consider additional pleural fluid studies (cell count, differential, culture, cytology, triglycerides).

However, for parapneumonic effusions, a low pleural fluid pH level is more predictive of complicated effusions (that require drainage) than is a low pleural fluid glucose level. In such cases

The only indication for measuring pleural fluid amylase is when pancreatic disease, oesophageal rupture or malignancy is being considered. 70-72 The definition of elevated pleural fluid amylase is a level greater than the upper limits of normal serum amylase and a pleural fluid to serum ratio >1.0. In cases of pancreaticopleural fistula, amylase levels may exceed 100 000 IU/L. In patients with high levels of … Pleural fluid characteristics of 26 patients diagnosed with malignant mesothelioma over an 18-year period were reviewed and compared with those of patients with effusions due to other malignancies. Survival from time of initial thoracentesis was directly correlated with pleural pH and decreased pleural fluid/serum glucose ratios but was not related to protein or LDH concentration. Decreased pleural fluid …

23-12-2010 · INTRODUCTION. Pleural fluid (PF) analysis, in combination with a targeted history, complete physical examination, and chest imaging, allows the physician to make a definitive or confident clinical diagnosis in the majority of patients with pleural effusion. 1 This review is a succinct compilation of the pieces of wisdom (pearls) gathered from clinical experience in the management of pleural effusions … 01-04-2012 · A basic biochemical exploration of an MM-associated pleural effusion should include protein electrophoretic analysis of the serum and pleural fluid, combined with an anatomic pathology study.

    Pleural fluid analysis is a test that examines a sample of fluid that has collected in the pleural space. This is the space between the lining of the outside of the lungs (pleura) and the wall of the chest. When fluid collects in the pleural space, the condition is called pleural effusion.
