Peripheral arterial line - infants

PAL - infants; Art line - infants; Arterial line - neonatal

Information

A peripheral arterial line (PAL) is a small, short, plastic catheter that is put through the skin into an artery of the arm or leg. Health care providers sometimes call it an "art line." This article addresses PALs in babies.

WHY IS A PAL USED?

Providers use a PAL to watch your baby's blood pressure. A PAL can also be used to take frequent blood samples, rather than having to draw blood from a baby repeatedly. A PAL is often needed if a baby has:

  • Severe lung disease and is on a ventilator
  • Blood pressure problems and is on medicines for it
  • Prolonged illness or immaturity requiring frequent blood tests

HOW IS A PAL PLACED?

First, the provider cleans the baby's skin with a germ-killing medicine (antiseptic). Then the small catheter is put into the artery. After the PAL is in, it is connected to an IV fluid bag and blood pressure monitor.

WHAT ARE THE RISKS OF A PAL?

Risks include:

  • The greatest risk is if the PAL stops blood from going to the hand or foot. Testing before the PAL is placed can prevent this complication in most cases. The NICU nurses will carefully watch your baby for this problem.
  • PALs have a greater risk for bleeding than standard IVs.
  • There is a small risk for infection, but it is lower than the risk from a standard IV.

      A peripheral arterial line is a small, short plastic catheter placed through the skin into an artery of the arm or leg. The purpose of a peripheral arterial line is to allow continuous monitoring of blood pressure and, when necessary, to allow frequent blood samples to be drawn for testing without needing to repeatedly stick your baby.
