Discharge Instructions for Thoracentesis

Choose a preferred language

Thoracentesis is a procedure that removes extra fluid from the pleural space. This space is between the outside surface of the lungs (pleura) and the chest wall. The extra fluid is called pleural effusion. Thoracentesis may be done to take a sample of the fluid. It can then be tested to help find the cause. Or the procedure may be done to drain the extra fluid if you are having trouble breathing.
