What is Paracentesis?
Paracentesis is a procedure that removes abdominal fluid buildup known as ascites. This buildup may result from infection, inflammation, injury, or issues. The ascites is removed with a long, thin needle that is inserted through the belly. The fluid is sent to a lab to determine the cause. Paracentesis can also remove fluid and relieve abdominal pressure or pain in people with cancer or cirrhosis.
Why is it Done?
Paracentesis is conducted to:
- Determine what is causing abdominal fluid buildup.
- Diagnose infection in the peritoneal fluid.
- Check for cancer, such as liver cancer.
|
- Remove fluid that is causing pain or difficulty breathing or affecting kidney or the bowel function.
- Check for damage after an abdominal injury.

How to Prepare?
Before paracentesis is done, make sure you let your doctor know if:
- You are on medication.
- You have bleeding problems or take blood thinners, such as aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), or warfarin (Coumadin).
|
- You have medical allergies, including anesthetics.
- You are, or might be, pregnant.
|
Other blood tests may be done before the paracentesis to make sure you do not have bleeding or clotting problems. You will also be asked to sign a consent form.
