Chest Fluid Drainage (Thoracentesis) - About the Exam
Mountain Medical radiologists perform thoracentesis, a minimally invasive procedure used to diagnose and treat pleural effusions, a condition in which there is excess fluid in the chest.
What you can expect a routine thoracentesis:
- A chest x-ray may be performed before a thoracentesis.
- This procedure is often done on an outpatient basis. However, some patients may require admission following the procedure.
- You will be positioned on the edge of a chair or bed with your head and arms resting on an examining table.
- Your physician will numb the area with a local anesthetic.
- The area of your body where the needle is to be inserted will be sterilized and covered with a surgical drape.
- The needle is inserted through the skin between two ribs on your back. When the needle reaches the pleural space between the chest wall and lung, the pleural fluid is removed through a syringe or suction bottle.
- Thoracentesis is usually completed within 15 minutes.
- At the end of the procedure, the needle will be removed and pressure will be applied to stop any bleeding. The opening in the skin is then covered with a dressing. No sutures are needed.
- A chest x-ray may be performed after thoracentesis to detect any complications.
