Abdominal Paracentesis

Questions? Call
Appointments by referral only.

Some conditions cause fluid build-up in the abdomen, called ascites. An abdominal paracentesis procedure uses a needle to remove a sample of the fluid or to drain it completely.

    Fluid in the abdomen can:

    • Make breathing difficult
    • Cause pain

    Abdominal fluid can return until the condition causing it has been treated. You may need to have the procedure again.

    Causes may include:

    • Bleeding
    • Infection
    • Diseases of organs, such as the liver
    • Cancer

    • Infection
    • Accidental piercing of structures in the abdomen

    The Paracentesis Procedure

    Before the Procedure

    Your doctor may conduct imaging scans, like MRIs or X-rays.

    If the procedure is scheduled and not done on an emergency basis:

    • Do not eat or drink for 12 hours before the procedure.
    • Empty your bladder just before the procedure.

    During the Procedure

    Performed in a clinic, this procedure:

    • Takes 10-15 minutes, depending on how much fluid needs to be removed. 
    • Requires some local anesthesia to numb discomfort

    Signs of Concern

    Call your doctor if any of the following occurs:

    • Signs of infection, including fever, chills and abdominal pain
    • Redness, swelling, increasing pain, excessive bleeding or fluid from the paracentesis site
    • Pain that you cannot control with the medicines you have been given
    • Cough, shortness of breath, feeling faint or chest pain
    • Swelling of the abdomen

    In case of an emergency, call for medical help right away.
