Paracentesis

There is a very small chance that the paracentesis needle may poke the bladder, bowel, or a blood vessel in the belly.

If cancer cells are present in the peritoneal fluid, there is a small chance that the cancer cells may be spread in the belly.

If a large amount of fluid is removed, there is a small chance that your blood pressure could drop to a low level. This could lead to shock. If you go into shock, IV fluids or medicines, or both, may be given to help return your blood pressure to normal. There is also a small chance that removing the peritoneal fluid may affect how your kidneys work. If this is a concern, IV fluids may be given during the paracentesis.

• A fever higher than 100°F (38°C).
• Severe belly pain.
• More redness or tenderness in your belly.
• Blood in your urine.
• Bleeding or a lot of drainage from the site.
