Section VII. DISORDERS INVOLVING THE LOWER RESPIRATORY SYSTEM
2-41. PLEURISY
a. Inflammation of the visceral and parietal pleura is called pleurisy. When the inflamed membranes rub together during respiration, it causes a severe, sharp pain. During the dry stage, a pleural friction rub can be heard on auscultation. Later, fluid develops between the inflamed pleura and the pain lessens.
b. This inflammation may occur after chest trauma or thoracotomy, may be associated with cancer, or may accompany upper respiratory infections, pneumonia, or tuberculosis.
c. The physician must discover the underlying cause of the inflammation and treat it. Along with the treatment of the primary cause, symptomatic treatment should be utilized for the effects of the pleurisy. Applications of heat or cold may ease discomfort. Analgesics should be used to decrease the pain. Anti-inflammatory drugs are also useful in decreasing the painful inflammation of the pleura. Additionally, the patient should be closely observed for signs indicating the development of pleural effusion.
