Pleural Effusion - StatPearls - NCBI Bookshelf
2024年8月31日 · Pleural effusion is the abnormal accumulation of fluid within the pleural space, the thin cavity between the pleural layers surrounding the lungs. Pleural effusions can arise from various etiologies, ranging from heart failure and pneumonia to malignancies, such as lung cancer, and systemic inflammatory disorders, such as lupus.

2023年7月24日 · Pleural effusions are collections of excess fluid within the pleural space. They are generally categorized as either transudative or exudative as determined by thoracentesis and fluid analysis. The Light’s Criteria is commonly used to identify an exudate.
Anatomy and Applied Physiology of the Pleural Space
The unique anatomy and physiology of the pleural space provides tight regulation of liquid within the space under normal physiologic conditions. When this balance is disrupted and pleural effusions develop, there can be significant impacts on the respiratory system.
Pleura: Anatomy, Physiology, and Disorders - PMC - PubMed …
Disorders of the pleura and pleural space reflect some of the oldest diseases encountered in surgical history. Hippocrates described the symptoms of empyema 2400 years ago: “Empyema may be recognized by the following symptoms: In the first place the fever is constant, less during the day and greater at night, and copious sweats supervene.
Physiology, Pleural Fluid - StatPearls - NCBI Bookshelf
2023年8月28日 · Pleural fluid serves a physiologic function in respiration, while also being a useful measure to diagnose and assess disease, trauma, and other abnormalities. A brief review of the anatomy and physiology of normal pleural fluid gives a point of reference for assessing the causes of abnormal pleural fluid collections and pleural effusions. [1][2][3]
Anatomy and Pathophysiology of the Pleura and Pleural Space
As free-moving fluid, pleural effusions initially collect at the subpulmonic area between the inferior surface of the lower lobes and the diaphragmatic leaflets. Up to 75 mL can collect in this area before it spills over into the costophrenic sulcus.
Pleural Effusion - Pleural Effusion - Merck Manual Professional Edition
Normally, 10 to 20 mL of pleural fluid, similar in composition to plasma but lower in protein (< 1.5 g/dL [< 15 g/L]), is spread thinly over the visceral and parietal pleurae, facilitating movement between the lungs and chest wall.
Pleural Effusion - Geeky Medics
2021年2月5日 · Pleural effusion: accumulation of fluid in the pleural space, the area between the visceral and parietal pleura. Transudative: low protein <25g/L; due to disruption in hydrostatic/oncotic pressures (e.g., heart failure, cirrhosis). Exudative: high protein >35g/L; due to increased pleural/capillary permeability (e.g., infection, malignancy).
Pleural effusion: diagnosis, treatment, and management - PMC
A pleural effusion is an excessive accumulation of fluid in the pleural space. It can pose a diagnostic dilemma to the treating physician because it may be related to disorders of the lung or pleura, or to a systemic disorder. Patients most commonly present with dyspnea, initially on exertion, predominantly dry cough, and pleuritic chest pain.
