Abdominal paracentesis removes extra fluid from the belly. A needle is inserted into the belly to draw the fluid out.
Reasons for Procedure
Ascites is the build-up of fluid in the belly. This may be done to:
- Take out a sample of fluid for testing to find a cause
- Drain the fluid out
- Ease breathing problems
- Ease pain
The fluid may return if the cause has not been treated. You may need to have this done again.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems such as:
- Damage to nearby structures

What to Expect
Prior to Procedure
Your doctor may do:
If the procedure is scheduled (not an emergency):
- Don't eat or drink for 12 hours beforehand.
- Empty your bladder just before the procedure.
You will receive local anesthesia. You will be awake, but the area will be numb.
Description of the Procedure
The area where the needle will be placed is cleaned. A drape will be put over the area. The numbing medicine will be injected nearby. A needle will be carefully inserted into the belly. The fluid will be drawn out through the syringe.
The amount of fluid that is removed will depend on your needs. A sample of fluid may be sent for testing. If you still have problems, more fluid will be removed until you feel better.
How Long Will It Take?
About 10-15 minutes, depending on how much fluid needs to be removed
How Much Will It Hurt?
The anesthesia will block pain during the procedure. Medicines will help ease pain afterwards.
You will stay in the recovery room for a few hours. Your blood pressure and other vital signs will be watched. If you have a lot of fluid leakage or are having trouble breathing, you may need to stay in the care center.
You will be able to return to normal activities. You will need to check on the insertion site to watch for signs of infection.
