Generally, a chest x-ray is done after the procedure to evaluate the lungs. Possible complications of thoracentesis include the following: *

, or buildup of air in the pleural space, with a collapsed or partially collapsed lung. Sometimes air comes in through the needle or the needle makes a hole in the lung. Usually, a hole seals itself—but sometimes air builds up around the lung and makes it collapse. A chest tube removes the air and lets the lung expand again. The lung fluid is examined under a microscope and is evaluated for the presence of chemicals and for its color and texture. The degree of clarity is an indicator of infection, cancer, or other conditions that may be causing the buildup of fluid or blood in the pleural space.

If tuberculosis or cancer is suspected, a small piece of the pleura may be examined under a microscope to make a definitive diagnosis. This is called a

Treatment

Treatment has several goals: * Relief of symptoms * Removal of the fluid, air, or blood from the

* Treatment of the underlying condition

Procedures

If large amounts of fluid, air, or blood are not removed from the pleural space, they may cause the lung to collapse. The surgical procedures used to drain fluid, air, or blood from the

are as follows: * During thoracentesis, a needle or a thin, hollow, plastic tube is inserted through the ribs in the back of the chest into the chest wall. A syringe is attached to draw fluid out of the chest. This procedure can remove more than 6 cups (1.5 litres) of fluid at a time. * When larger amounts of fluid must be removed, a chest tube may be inserted through the chest wall. The doctor injects a local painkiller into the area of the chest wall outside where the fluid is. A plastic tube is then inserted into the chest between two ribs. The tube is connected to a box that suctions the fluid out. A chest x-ray is taken to check the tube's position. * A chest tube is also used to drain blood and air from the pleural space. This can take several days. The tube is left in place, and the patient usually stays in the hospital during this time. * Sometimes the fluid contains thick pus or blood clots, or it may have formed a hard skin or peel. This makes it harder to drain the fluid. To help break up the pus or blood clots, the doctor may use the chest tube to put certain medicines into the pleural space. These medicines are called

fibrinolytic Fibrinolysis is a process that prevents blood clots from growing and becoming problematic. Primary fibrinolysis is a normal body process, while secondary fibrinolysis is the breakdown of clots due to a medicine, a medical disorder, or some other ...

s. If the pus or blood clots still do not drain out, surgery may be necessary.

Lifestyle changes

The following may be helpful in the management of pleurisy: * Lying on the painful side may be more comfortable * Breathing deeply and coughing to clear mucus as the pain eases. Otherwise,

may develop. * Getting rest

Treating the cause

Ideally, the treatment of pleurisy is aimed at eliminating the underlying cause of the disease. * If the pleural fluid is infected, treatment involves antibiotics and draining the fluid. If the infection is tuberculosis or from a fungus, treatment involves long-term use of antibiotics or antifungal medicines. * If the fluid is caused by tumors of the pleura, it may build up again quickly after it is drained. Sometimes anti-tumor medicines prevent further fluid buildup. If they don't, the doctor may seal the pleural space. This is called

pleurodesis Pleurodesis is a medical procedure in which part of the pleural space is artificially obliterated. It involves the adhesion of the visceral and the costal pleura. The mediastinal pleura is spared. Uses Pleurodesis is performed to prevent recurre ...

. Pleurodesis involves the drainage of all the fluid out of the chest through a chest tube. A substance is inserted through the chest tube into the pleural space. This substance irritates the surface of the pleura. This causes the two layers of the pleurae to squeeze shut so there is no room for more fluid to build up. *
