The accumulation of fluid in the pleural space, referred to as a pleural effusion, usually indicates an underlying abnormality. A thoracentesis may be performed to identify the reason (diagnostic) and/or to relieve the discomfort and symptoms (therapeutic) of excessive fluid in the pleural space. A diagnostic thoracentesis involves the removal of fluid for analysis (pleural fluid analysis).
If you are unable to seat the patient due to hemodynamic status, mental status or because of tubes and indwelling lines, the Thoracentesis has to be done in the supine position. Turn the patient on his side and bring his back to the edge of the bed. You will be able to accomplish the Thoracentesis in this position. Be aware that the dependent diaphragm moves up. Let me show you a lateral decubitus chest x-ray to demonstrate the upward movement of the dependent diaphragm. Select the 5th or 6th interspace to avoid possible injury to the diaphragm.
