Abdominal Paracentesis


Abdominal paracentesis is a procedure to remove abnormal fluid buildup in your abdomen. Fluid builds up because of liver problems, such as swelling and scarring. Heart failure, kidney disease, a mass, or problems with your pancreas may also cause fluid buildup.



  • Diuretic: This medicine removes extra fluid and prevents new fluid buildup. You may urinate more often when you take this medicine.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Do not drink alcohol:

Alcohol can interact with the medicine you take after your paracentesis.

Wound care:

Ask your healthcare provider when you can remove your bandage, and how to care for your wound.

Eat low-salt foods:

Salt causes fluid to build up. Limit your salt intake to 2 grams each day. Do not add salt to your food. Try to cook your own food and avoid fast food or processed food. Read the labels on your food to see how much salt they contain.

Return to your normal activities:

Ask your healthcare provider which activities are safe for you to do. You may need to build up to your normal activity level slowly.

Contact your healthcare provider if:

  • You have a fever and your wound is red and swollen.
  • You have yellow, green, or bad-smelling discharge coming from your wound.
  • You have pain or swelling in your abdomen.
  • You have an upset stomach or you vomit.
  • Your legs and ankles are swollen.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You have sudden, sharp pain in your abdomen.
  • You urinate very little or not at all.
  • You feel confused and more tired than usual.
  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.
  • You suddenly feel lightheaded and have trouble breathing.
  • You have chest pain. You may have more pain when you take a deep breath or cough. You may cough up blood.
