Thoracentesis is a procedure where a needle is put into the space between your rib cage and one of your lungs, called the pleural space, to drain fluid. The pleural space normally contains a small amount of fluid. Thoracentesis may be needed to test the fluid for infection or cancer cells. It may also be needed when excess fluid is putting pressure on the lung and making it hard to breathe. This excess fluid is called a pleural effusion.
