What To Think About


  • A paracentesis is often done when signs or symptoms of peritonitis develop.
  • Pregnant women may not have this test done because there is a chance that the paracentesis needle could poke the uterus and injure the baby (fetus).
  • Sometimes doctors use fluids put into the belly to check for injuries. This is called peritoneal lavage. During this procedure, a doctor uses a paracentesis needle to put a salt (saline) fluid into the belly. The fluid is then taken out through the same needle. If the fluid that comes out is bloody, the bleeding is probably being caused by an injury inside the belly.
