What Is a PICC Line? How It's Placed, Cared For, and Used in Home Infusion
If you are starting home infusion therapy, there is a good chance your physician has mentioned a PICC line, or you already have one placed. PICC lines are the most commonly used IV access device for home infusion because they are reliable, relatively easy to insert, and appropriate for most therapy durations from a few days to several months.
This guide explains what a PICC line is, how it gets placed, how to care for it at home, and what warning signs to watch for throughout your therapy.
What Is a PICC Line?
PICC stands for Peripherally Inserted Central Catheter. It is a long, thin, flexible tube inserted into a vein in the upper arm, typically the basilic or brachial vein, and advanced through the venous system until the tip rests in the superior vena cava, just above the heart. This central position allows medications that would damage smaller peripheral veins (such as certain antibiotics, TPN, and chemotherapy) to be diluted by the high-volume blood flow near the heart.
Despite the word 'peripheral' in its name (referring to its insertion site in the arm), a PICC is classified as a central line because its tip is in the central venous system. Pharmko trains every home infusion patient on PICC line care before their first dose.
How Is a PICC Line Inserted?
PICC insertion is a sterile, bedside procedure typically performed by a specially trained nurse or interventional radiologist. It does not require general anesthesia or an operating room. The procedure involves:
- Cleaning and draping the insertion site on the upper arm
- Using ultrasound guidance to identify the target vein
- Inserting a thin introducer needle, then threading the PICC catheter through it
- Advancing the catheter to the correct tip position, confirmed by X-ray before use
- Securing the catheter with a stabilization device and applying a sterile dressing
The procedure takes approximately 30 to 60 minutes and is usually performed in a hospital, infusion suite, or by a home health nurse at your residence.
Types of PICC Lines
Single-lumen PICC
Has one opening (lumen) at the tip, appropriate for single-drug infusions such as IV antibiotic therapy. Most home infusion patients use a single-lumen PICC.
Double or triple-lumen PICC
Has two or three lumens, allowing multiple medications or fluids to be infused simultaneously without mixing. Used when patients require concurrent IV therapies or frequent blood draws.
Power-injectable PICC
Rated for high-pressure injection (e.g., CT contrast). If you may need imaging studies during your therapy, your physician may specify a power-injectable PICC.
How to Care for Your PICC Line at Home
PICC line care at home centers on three daily practices:
1. Dressing changes
The transparent dressing covering the insertion site must be changed when it becomes wet, loose, or visibly soiled — typically every 5 to 7 days under normal conditions. Your Pharmko nurse performs scheduled dressing changes and teaches you or your caregiver the sterile technique. Our full guide on central line care at home covers the complete dressing change process step by step.
2. Flushing
The catheter must be flushed with saline (and sometimes heparin) before and after each infusion, and on days when no infusion occurs, to prevent clotting and maintain patency. Your nurse will specify the flush schedule and demonstrate the correct technique during your training.
3. Protecting the line
Avoid submerging the arm in water (baths, swimming pools, hot tubs). Showering is permitted with a waterproof cover over the insertion site. Avoid heavy lifting or forceful arm movements that could dislodge the catheter.
Warning Signs That Require a Call
Contact your Pharmko care team immediately if you notice any of the following:
- Redness, warmth, swelling, or drainage at the insertion site
- Fever or chills, especially during or after an infusion
- Pain, numbness, or swelling in the arm above the PICC
- The catheter appears to have moved (more of the external segment is visible)
- Resistance when flushing, or inability to flush the catheter
