Thoracentesis

Thoracentesis or pleural fluid aspiration is a procedure that involves removal of fluid from the space between the lining of the pleura and the chest wall. Fluid is withdrawn with the aid of a needle passed through the skin of the chest wall into the pleural space. An analysis of the pleural effusion can indicate pulmonary embolism, hemothorax, pancreatitis, pneumonia, heart failure or thyroid disease. Thoracentesis can aid in relieving pressure caused by accumulation of excess pleural fluid. A chest x-ray is taken before and after the thoracentesis process. Do not move or cough while the diagnostic test is being conducted. Patients who have had lung surgery or lung disease such as emphysema may have difficulty with thoracentesis. Pneumothorax, pulmonary edema or respiratory distress are rare complications associated with thoracentesis. It is essential to keep the doctor posted of any medications such as blood thinners or known allergies.
