Paracentesis Ultrasound 

An ultrasound Paracentesis is an exam to drain off fluid in the abdomen.

The Procedure:

You will be lying on your back for this exam. The ultrasound technologist will scan your abdomen to locate the pocket of fluid. The Radiologist (x-ray doctor) will insert a needle/catheter into the abdomen and the fluid will be drained off.

The needle will be removed after the procedure is complete. Your abdomen will be rescanned after the fluid has been removed. You may be asked to stay for a few hours after your procedure for observation if the Radiologist requests it.

Procedure time: 60 - 90 minutes

Inpatient and Outpatient Preparation Instructions:

  1. You may be required to have blood work prior to your procedure. The Medical Imaging Department will call you prior to your exam. Outpatient registration will have a copy of your lab work, if needed.
  2. Do not eat or drink 2 hours prior to your test.
  3. You will need someone available to drive you home, only if it becomes necessary.
  4. You can take your normal medications with a small amount of water unless you are on:
    • Aspirin, Coumadin, Plavix or other blood thinners (stop these medications 3-5 days before test)
  5. You will be asked to stay for up to 2 hours before being discharged. You will be given discharge instructions prior to leaving.

For Your Information:

  1. After registration you will go to an observation area prior to your exam. You will be asked to change into a hospital gown and assessed prior to going to the Medical Imaging Department. You will be taken back to this area following your exam for a follow-up assessment prior to leaving.
  2. An IV may be started in your hand or arm, only if the Radiologist requests it.
  3. Relax and follow instructions given to you by the ultrasound staff.
  4. The Radiologist will give the results to your doctor. Your doctor will share the results with you; feel free to ask any questions.
