Ultrasound Paracentesis

An ultrasound paracentesis is a procedure in which a needle is inserted through your abdominal wall into your abdominal cavity to remove or collect fluid accumulation (called ascities).

A paracentesis is done to help determine the cause of fluid build up in the abdominal cavity and/or to remove large amounts of the ascitic fluid that is causing pain or other difficulties.

During the paracentesis, a registered sonographer will move a hand-held device over your abdomen. With the ultrasound pictures as a guide, the radiologist will select the best site to insert the needle. This site is then cleaned with an antiseptic solution and a local anesthetic (numbing medication) is injected. You may feel a burning or stinging as the anesthetic is injected. When the abdominal cavity is entered, fluid will flow into a syringe. If a large amount of fluid is present, the needle may be attached to a bottle. Generally, up to one liter of fluid is removed. The fluid may then be sent to the lab to be examined under the microscope. Length of the exam is 20-30 minutes.

After the procedure, expect to rest and be monitored for 1-2 hours. The lab will send your fluid analysis results to your physician. Nurses will instruct you in activity restrictions and general care before you return home.

Providing safe, quality patient care is our highest priority. To help ensure quality and safety, we ask that you do not bring young children with you to your appointments, as children are not allowed to accompany you during Imaging procedures. Staff is unable to monitor your child in your absence.
