28 Αυγ 2023 · Introduction. Pleural fluid serves a physiologic function in respiration, while also being a useful measure to diagnose and assess disease, trauma, and other abnormalities.
16 Φεβ 2024 · In addition to its diagnostic value, pleural fluid analysis also has predictive value (ie, estimates of the likelihood of a clinical response to pleural fluid drainage) and prognostic value (eg, likelihood of disease recurrence or progression in malignant pleural effusion).
5 Ιουν 2012 · Pleural effusions due to pulmonary embolism. Pleural effusions occur in 30% to 50% of patients with pulmonary emboli. It is possible that a significant number of undiagnosed effu-sions are due to pulmonary embolism. The fluid may be transudative (24%) or exudative, depending on the mechanism.
1 Μαρ 2013 · PDF | Although a pleural effusion (PE) is a common condition in clinical practice (with a prevalence of slightly >400 patients/100,000), a definitive... | Find, read and cite all the research...
Definition of pleural effusion. Accumulation of fluid between the pleural layers. Epidemiology of pleural effusion. Estimated prevalence of pleural effusion is 320 cases per 100,000 people in industrialized countries, with a distribution of etiologies related to the prevalence of underlying diseases. Causes of pleural effusion.
The limited specificity of Light’s criteria (ie, misclassification of transudates as exudates) can be overcome with the examination of the serum to pleural fluid protein gradient, the serum to pleural fluid albumin gradient, or the pleural fluid levels of N-terminal pro-brain natriuretic peptide.
The major value of pleural fluid pH is to determine the need for chest tube drainage in parapneumonic effusions and to determine the response to sclerosing agents in patients with malignant pleural effusions.
