Thoracentesis
This topic will help you learn about the thoracentesis procedure and how to prepare for it.
What Is the Thoracentesis Procedure?
Thoracentesis is a surgical procedure used to remove excess fluid from the space between the lungs using a needle. The procedure is performed to test the fluid for infection or other diseases and to relieve chest pressure that makes breathing difficult. Thoracentesis is a short, low-risk procedure performed by specialist doctors.
When Is a Thoracentesis Performed?
If you have a pleural effusion (fluid around the lungs), you may need a thoracentesis to investigate the cause, or to improve the symptoms of the effusion, or both.
- Common reasons for performing thoracentesis include:
- Infection: If your healthcare provider suspects you have a contagious illness (such as a bacterial infection) causing pleural effusion, they will remove some fluid for testing.
- Cancer: If cancer is causing the pleural effusion, the doctor can test the pleural fluid for cancer cells.
Symptom Relief: If the pleural effusion is making breathing difficult, the doctor can remove some fluid to make you more comfortable.
How to Prepare for a Thoracentesis?
- Your doctor will provide precise instructions on how to prepare for a thoracentesis, which can be summarized as follows:
- The doctor will explain the procedure in detail, and you can ask questions.
- You will be asked to sign a consent form giving permission to perform the procedure. Read the form carefully, and ask questions if there is anything unclear.
- Inform the doctor if you have any allergies to medications or anesthesia.
- Inform the doctor of all medications (prescribed and over-the-counter), vitamins, herbs, and supplements you take.
- Inform the doctor if you have a history of bleeding disorders or if you are taking any blood-thinning medications (anticoagulants), aspirin, or other medications that affect blood clotting. You may be asked to stop these medications before the procedure.
