Pleural fluid

Pleural fluid is a serous fluid produced by the pleura, the thin tissue layer that lines the thoracic cavity and surrounds the lungs. This fluid serves to lubricate the pleural surfaces and allows smooth movement of the lungs during respiration.

Production and Function

The pleural fluid is produced by the pleura and is reabsorbed by the lymphatic system. It is a clear, straw-colored fluid that contains water, proteins, lipids, and a small number of white blood cells. The primary function of the pleural fluid is to reduce friction between the pleural surfaces during respiration. It also helps to maintain the position of the lungs against the chest wall.

Pleural Fluid Analysis

Pleural fluid analysis is a group of tests used to diagnose the cause of pleural effusions. These tests may include a physical examination, chemical analysis, microbiological analysis, and cytological analysis. The results of these tests can help to determine the cause of the pleural effusion and guide treatment decisions.

Pleural Effusion

A pleural effusion is an abnormal accumulation of pleural fluid in the pleural space. It can be caused by a variety of conditions, including heart failure, pneumonia, tuberculosis, and cancer. Symptoms of a pleural effusion may include shortness of breath, chest pain, and cough.

Treatment

Treatment of pleural effusions depends on the underlying cause. It may include medications to treat the underlying condition, procedures to remove the excess fluid, and in some cases, surgery.
