Thoracentesis
Overview
A procedure to remove a sample of fluid between the layers of the lung lining. The lung lining is called the pleural space and it is normally filled with a thin layer of fluid. In conditions such as pneumonia or heart failure, this space may accumulate more fluid than usual causing the patient to complain of shortness of breath. Physicians can insert a catheter through the skin, between the ribs and into this lining to remove the excess fluid or to send fluid to the lab for analysis. Topical anesthetic is administered before the procedure is started. The procedure is normally done with ultrasound guidance and is usually completed in fifteen minutes.
