It may be primary or secondary; unilateral, bilateral, or local; acute or chronic; fibrinous, serofibrinous, or purulent. Common causes of pleurisy include viral infections, pneumonia, pulmonary embolism, rib fracture, and serositis from autoimmune diseases. SYN: pleuritis.

SYMPTOMS: Sharp stabbing pain exacerbated by breathing is characteristic.

++

PATIENT CARE: Respiratory function is monitored by auscultation, observation of breathing pattern, and oximetry. The patient is positioned in the high Fowler position to facilitate chest expansion. Rest is encouraged. Deep breathing using incentive spirometry is encouraged every 1 to 2 hr to prevent atelectasis. To reduce discomfort when coughing, the patient should splint the chest with a pillow and administer analgesic drugs and use noninvasive measures, such as local application of warm or cool compresses. Respiratory toilet is provided if secretions are present. Rest is recommended. Prescribed medical regimens are carried out, with treatment directed at the underlying cause, and the patient's responses evaluated. Severe pain may be managed with intercostal nerve block. Thoracentesis may be required if pleural effusion is present.

++

diaphragmatic p. Inflammation of the diaphragmatic pleura. Symptoms include intense pain under the margin of the ribs, sometimes referred into the abdomen, with tenderness upon pressure; thoracic breathing; tenderness over the phrenic nerve referred to the supraclavicular region in the neck on the same side; hiccough; and extreme dyspnea.
