What is a PICC Line?

A PICC (Peripherally Inserted Central Catheter) is a long, thin, flexible tube that is inserted into a peripheral vein in the upper arm (commonly the basilic, cephalic, or brachial vein) and advanced until the tip rests in a large central vein near the heart—typically the superior vena cava.

It is a type of central venous catheter designed for medium- to long-term intravenous access, often remaining in place for weeks to several months when properly cared for.

Outside the body, the PICC may have one, two, or three smaller tubes called lumens. Each lumen ends with a needleless connector that allows medications, fluids, or blood sampling without additional needle sticks.

Why Do I Need a PICC Line?

Your healthcare provider may recommend a PICC line when you need reliable venous access for an extended period or when treatments would be irritating to smaller peripheral veins. Common reasons include:

• Long-term antibiotics or other intravenous medications
• Chemotherapy or targeted therapies that can damage smaller veins
• Total parenteral nutrition (TPN) — liquid nutrition delivered directly into the bloodstream
• Frequent blood draws or blood product transfusions
• Poor peripheral venous access or to minimize repeated needle sticks

A PICC can make treatment more comfortable and reduce the trauma of multiple peripheral IVs.

Patient Preparation for PICC Line Placement

Preparation is usually straightforward:

• Eating and drinking: In most cases you may eat and drink normally before the procedure. Fasting is typically not required.
• Clothing: Wear a short-sleeved or loose-sleeved shirt so the upper arm is easily accessible.
• Medications: Inform your care team about all medications, especially blood thinners (anticoagulants such as warfarin, apixaban, rivaroxaban, enoxaparin). Blood tests (for example, INR) may be ordered.
• Allergies: Report any known allergies or sensitivities to chlorhexidine (skin prep), latex, adhesives/tape, or local anesthetics (lidocaine).
• The procedure: Placement is performed by a trained clinician using ultrasound guidance and local anesthetic. You will feel pressure but should not feel sharp pain after the area is numbed. The procedure typically takes 30–60 minutes. Final tip position is confirmed by imaging (chest X-ray or other method).

Ask questions beforehand so you feel informed and prepared.

Care Instructions for a PICC Line

Proper care helps prevent infection, clotting, and mechanical problems. Follow the specific regimen given by your healthcare team. General principles include:

Dressing Care

• Keep the transparent dressing clean, dry, and securely adhered to the skin.
• Dressings are usually changed once every 7 days, or sooner if wet, dirty, loose, or damaged.
• The first dressing change often occurs within 24 hours after insertion to remove initial gauze.
• Dressing changes should be performed by a trained nurse or caregiver using sterile technique.

Flushing

• The line is flushed with sterile saline (and sometimes heparin) according to your provider’s schedule to keep it patent.
• Always scrub the needleless connector with an alcohol swab for 15–30 seconds before connecting anything.

Daily Hygiene & Activity

• Wash your hands thoroughly with soap and water before touching the PICC or dressing.
• Showering is preferred. Cover the entire dressing and external tubing with a waterproof barrier (plastic wrap or commercial PICC cover) secured with tape. Do not let the site get wet.
• Avoid baths, swimming, hot tubs, and any full submersion of the arm.
• Do not lift heavy objects (commonly limited to 5–10 pounds) or perform vigorous/repetitive arm movements (golf, tennis, vacuuming, jumping jacks) with the PICC arm.
• No blood pressure measurements, tourniquets, or blood draws on the arm with the PICC.
• Avoid tight clothing or anything that could pull or kink the external tubing.

Daily Checks

• Inspect the insertion site every day for redness, swelling, tenderness, warmth, drainage, or leakage.
• Check that the external catheter length looks the same and that connectors/caps are secure.
• Measure arm circumference if instructed, to monitor for swelling.

PICC Line Complication Signs

Recognizing problems early is important. Contact your healthcare provider promptly (or seek emergency care for severe symptoms) if any of the following occur.

Signs of Infection (Local or Bloodstream)

• Redness, warmth, swelling, or tenderness at or around the insertion site
• Drainage, pus, or leakage from the site
• Fever (often 100.4°F / 38°C or higher) or chills
• Feeling generally unwell, fatigue, or malaise
• Red streaking along the vein

Signs of Thrombosis (Blood Clot) or Phlebitis

• Swelling of the arm, hand, fingers, shoulder, neck, or face on the PICC side
• Pain, aching, or discomfort in the arm, shoulder, neck, or jaw
• Visible engorged or prominent veins in the arm or chest
• Warmth or redness along the vein path
• A firm, cord-like feeling along the vein

Signs of Occlusion (Blockage) or Mechanical Problems

• Difficulty or inability to flush the line
• Resistance when flushing or inability to draw blood
• Fluid leaking from the catheter, connector, or under the dressing
• Pain or discomfort when fluids are infused
• Frequent infusion pump alarms

Signs of Catheter Migration, Dislodgement, or Damage

• The external portion of the catheter appears longer or shorter than usual
• The catheter has been accidentally pulled or feels loose
• Leakage of fluid or blood at the exit site
• Visible crack, break, or hole in the catheter

Other Concerning Symptoms — Seek Urgent or Emergency Care

• Shortness of breath, chest pain, or cough
• Dizziness, lightheadedness, fainting, or confusion
• Rapid or irregular heartbeat / palpitations
• Numbness, tingling, or weakness in the arm, hand, or fingers on the PICC side
• Sudden severe arm or neck swelling

Practical tip: Inspect the insertion site and external catheter daily. Measure arm circumference if instructed, and note any changes from baseline. Report concerns early—many issues can be managed successfully if caught promptly.

When to Contact Your Healthcare Provider

Call your care team promptly for any of the signs listed above, or if you have questions about your PICC line. For severe symptoms such as shortness of breath, chest pain, fainting, or sudden severe swelling, seek emergency care.
