Umbilical Artery Catheter In Newborns

What do I need to know about an umbilical artery catheter?

An umbilical artery catheter (UAC) is a small flexible tube that is put into an umbilical cord stump artery. Your baby's umbilical cord stump has 1 vein and 2 arteries.

Why does my baby need a UAC?

  • To draw blood samples or give a transfusion

  • To measure the amount of oxygen and other gases in your baby's blood

  • To give IV fluids and medicines

  • To check blood pressure

What will happen during a UAC procedure?

Your baby will be placed on his back. His arms and legs may be secured so that he does not move during the procedure. Your baby's surgeon will place the catheter in the artery. An x-ray may be taken to check that the catheter is placed correctly. The surgeon may attach the catheter to the umbilical stump with stitches. The catheter will be taped to your baby's belly so that it cannot be pulled out.

What will happen after the UAC procedure?

You may not be able to hold your baby while the UAC is in. Comfort your baby by gently placing your hands on his arms or legs. Speak softly to your baby. Ask about the best ways to support your baby.

How is the UAC removed?

Your baby's healthcare provider will pull the catheter out. He will put a bandage over the umbilical stump and gently squeeze your baby's belly. This is to make sure the artery closes and does not bleed. Your baby's UAC may be removed for the following reasons:

  • Your baby's health is stable or improves.

  • The catheter causes an infection.

  • Your baby's catheter is blocked or no longer works.

  • The catheter causes problems with the artery.

What are the risks of a UAC?

Your baby may get an infection. The catheter may damage the artery and cause internal bleeding. Organs, such as your baby's kidneys or intestines, may be damaged. The catheter may cause spasms in your baby's blood vessels. Your baby may have trouble breathing or get a blood clot in his limb. This may become life-threatening.
