PICC Line

What is a PICC line?

A PICC line is a long, thin tube (catheter) that serves as a long-term IV. It is inserted through a vein on the inside of your child’s upper arm or in the upper leg. The line extends into a large vein near your child’s heart.

A PICC line is a type of central venous catheter (central line). PICC stands for peripherally inserted central catheter. A PICC line allows medicines, nutrition, blood products, and fluids to be given to your child. Blood samples can also be taken.

With good care, the line can stay in place for months before it needs to be removed and replaced. It is important to take care of the PICC line and follow all instructions to prevent infection and keep it working properly.

A PICC line is inserted into a vein on the inside of the upper arm and extends into a larger vein leading to the heart. One end of the catheter stays outside the skin and has one or two tubes called lumens.

How a PICC line works

The care team inserts the PICC line into a vein in the arm. They guide the line until it reaches a large vein near the heart. The end of the tubing comes out through an opening in the arm. 

One end of the PICC line stays outside the skin and has 1 or 2 tubes called lumens. Each lumen has a cap called a needleless connector placed on the end. The connectors keep the lumens from leaking. They also keep air and bacteria out. The connectors allow medicines and fluids to be given without needle sticks. Needleless connectors are usually changed every 7 days or more often if needed.

Your child will wear a dressing (bandage) over the area to protect against infection. The dressing also helps keep the line in place. 

Benefits of a PICC line

Benefits of a PICC line include:

  • A PICC line reduces the need for needle sticks for medicines, fluids, nutrition, blood products, and blood samples.
  • The care team can place a PICC line with your child having only mild sedation or none at all.
  • A PICC line is easy to access.
  • A PICC line can stay in place for a long time.
  • Some medicines can irritate your child’s blood vessels. A PICC line is placed in a large vein with high blood flow so there is less irritation.
  • You can give medicine through a PICC line at home, making it easier for your child to continue therapy.
  • With some types of PICC lines, you can give more than 1 type of medicine or liquid at the same time.
  • A PICC line can be removed without surgery in the clinic.

How a PICC line is placed

Knowing what to expect can help you and your child feel more comfortable before and during PICC line placement.

Risks of a PICC line

Every medical procedure has some risks, including those that involve anesthesia and surgery. Your child’s care team takes steps to keep these risks as low as possible.

Risks during PICC line placement

While the PICC line is being placed, possible risks include:

  • Puncture of a blood vessel
  • Blood clots forming in the vein
  • Irregular heartbeat
  • Nerve injury
  • Infection
  • Allergic reaction to contrast (x-ray dye) if used

Risks after PICC line placement

After the PICC line is placed, possible complications include:

  • Blood clots
  • Movement of the PICC line out of position
  • Inflammation or irritation of the vein
  • Infection

Important information

Serious problems are rare, but they can happen. Always ask questions if you are unsure about any part of the procedure. Follow all instructions from your child’s care team.

How to care for a PICC line 

Your care team will teach you how to care for the PICC line. Always follow your care team's instructions to keep the line working properly and take steps to prevent infection.

PICC lines must be flushed daily with heparin. Heparin is a medicine that keeps blood from clotting and blocking the line. Your child will wear a dressing over the area to prevent infection and keep the line in place. The dressing must be changed once a week. The dressing must also be changed if it gets wet, dirty, or comes off. It is important to keep the dressing from getting wet during bathing.

Early healing

It may take a few days to get used to the PICC line. Your child's arm may feel sore or stiff. There may be some bruising.

It may feel like the line is pulling on the outside of the skin.

Your child can return to most normal activities as soon as they feel like it. Your child should avoid strenuous activities, such as contact sports, rough play, and weightlifting while they have a PICC line.

Living with a PICC line

Medicines can be given with a syringe or an IV bag. Let your care team know if your child has any pain or discomfort while getting medicines.

Follow all care instructions to keep the line working properly and to prevent infection. Always wash your hands before touching the PICC line. Clean the needleless connector before each connection to the line.

Your child should avoid activities that could damage the line, such as contact sports or rough play. Your child should not swim or submerge in water with a PICC line because it increases the risk of infection. Tell your child’s teachers, school nurses, and other caretakers about the PICC line.

Make sure the line is secured, and keep a clean, dry dressing over the site at all times. Watch for cracks or other signs of damage to the line.

Preventing infection

Patients with a central line are at risk for a serious infection known as a central line-associated blood stream infection (CLABSI), which can be life-threatening. To help prevent infection: 

  • Always wash your hands before and after doing any line care. 
  • Keep the central line site clean and dry. 
  • Make sure the dressing is changed every 7 days or more often if needed.
  • Make sure your child bathes and changes clothing daily. 
  • Change your child’s bed linens once a week, or more often if they are soiled. 
  • Practice good oral care to reduce mouth bacteria, including brushing teeth twice a day. 
  • Seek medical care right away at any sign of infection, such as pain, redness, swelling, or fever.  

When to call your care team

Call your care team if you notice any of the following: 

  • Redness, pain, warmth, or swelling at the PICC line site that gets worse or does not get better in 24 hours
  • Blisters, bruising, dark color, or peeling of the skin at the PICC line site
  • Fluid, blood, or pus leaking from the PICC line site 
  • Numb, tight, or cool feeling at the PICC line site  
  • Fever of 100.4°F (38°C) or higher, or as directed by your care team
  • Chills, nausea, shortness of breath, fast heartbeat, dizziness, or confusion
  • The PICC line is blocked, leaking, or will not flush
