Paracentesis helps doctors remove fluid from the stomach area using a soft, hollow tube called a catheter. This can reduce pressure and discomfort in the stomach. A sample of the fluid is then sent to the lab to find out what’s causing the buildup.
About the procedure
You will lie flat on your back with your head raised on a pillow or cushion. We'll use ultrasound to find the best place in the abdomen to get a fluid sample.
We'll clean the skin area with surgical soap and use a local anesthetic to numb the area.
Next, we'll put in the paracentesis needle and catheter. The needle and catheter will be attached to a small bottle to help drain the fluid. After enough fluid has been drained, we'll remove the catheter and cover the area with a bandage.OR
You shouldn't take any blood thinners, including vitamin E and aspirin, for one week before your exam. Please talk to your doctor before you stop taking any of your medications.
The day before your exam
You'll need a prothrombin time (PT) test. It measures platelets and other parts of the blood to see how quickly your blood clots (stops bleeding). PT results are given in a measurement called INR (international normalized ratio).
On the day of your exam
Wear a comfortable two-piece outfit to your appointment.OR
