The procedure is more time consuming then anything
You may have a little discomfort, not bad, they will
keep you comfortable.
Once you get this done , you will feel a lot better.

Paracentesis for Ascites
“The procedure is often done in a doctor's office or an outpatient clinic. In an expert's hands, it is very safe, although there is a very small risk of introducing an infection, causing excessive bleeding or perforating a loop of bowel. Some of these risks can be minimized greatly with the use of ultrasound guidance.
During the procedure, patients are asked to lie down and expose their abdomen. After cleaning the side of the abdomen with an antiseptic solution, physicians will numb a small area of skin and then insert a fairly large-bore needle (along with a plastic sheath) 2 to 5 cm to reach the peritoneal (ascitic) fluid. The needle is then removed, leaving the plastic sheath behind to allow drainage of the fluid. The fluid can be drained by gravity or by connection to a vacuum bottle. Up to 11 litres of fluid may be drained during the procedure. If fluid drainage is more than 5 litres, patients may receive intravenous serum albumin (25% albumin, 8g/L) to prevent hypotension (low blood pressure).
The procedure generally is not painful; patients require no sedation. As long as they are not too dizzy and maintain their blood pressure after the procedure, they can go home afterwards.”
