Amniocentesis

ExitCare Image Amniocentesis (amnio) is when the doctor removes fluid from the sac that surrounds the baby (amniotic sac). The fluid may be looked at to find out if:

  • There are problems with the baby.

  • There is an infection in the womb (uterus).

  • The baby's lungs have grown enough to live outside the womb.

BEFORE THE PROCEDURE

  • Make sure to ask your doctor questions if you have them.

  • Eat as usual.

  • Drink enough fluids to keep your pee (urine) clear or pale yellow.

  • Plan to have someone drive you home after the test.

PROCEDURE

  • An ultrasound test will be done to look at the baby's position.

  • A solution is put on your belly (abdomen). This stops infection from happening.

  • A shot may be given to numb the area where the long needle will go.

  • A long needle is put into the belly and into the amniotic sac. A germ-free (sterile) probe may be used to watch the amnio needle go in.

  • Amniotic fluid is removed.

  • The fluid is sent to the lab and looked at carefully.

AFTER THE PROCEDURE

  • Ask your doctor if you need a shot called RhoGam.

  • You will rest for 1 to 2 hours at the doctor's office.

  • Your baby will be monitored for 1 to 2 hours at the doctor's office.

  • You may have cramps or a small amount of bleeding from the vagina. If this happens, it will be right after the test.

  • Ask when your test results will be ready. Make sure you get your test results.
