Information

A peripheral arterial line (PAL) is a small, short plastic catheter that is placed through the skin into an artery of the arm or leg. This article discusses the use of PALs in babies.

WHY IS A PAL USED?

The main reason to use a PAL is to continuously watch your baby’s blood pressure. It also allows the health care team to take frequent blood samples without needing to stick your baby more than once. A PAL is most often used if your baby has severe lung diseasethat needsmechanical ventilation, or blood pressure problems requiring the use of very strong medications.

HOW IS A PAL PLACED?

After cleaning the baby's skin with a germ-killing medicine (antiseptic), the health care provider inserts the small catheter into the artery and connects it to an IV fluids bag and blood pressure monitor.

WHAT ARE THE RISKS OF A PAL?

The most serious risk is aninterruption of the blood supply to the hand or foot. Testing before the PAL is placed can usually prevent this complication. The NICU nurses will carefully monitor your baby for this possible problem.

There is a greater risk for bleeding compared to standard IVs, but theinfectionrisk is lowerwith PALs.
