PICC Line Insertion & Maintenance

Question 1

What is the ideal vein for PICC insertion?

Accepted Answer

Basilic vein

Answer

The basilic vein is generally considered the ideal vein for PICC insertion due to its large diameter, straight course, and superficial location in the upper arm. These characteristics make it easier to access and navigate the catheter, reducing the risk of complications like nerve damage or vessel trauma. Its size also allows for better blood flow around the catheter, minimizing the risk of thrombosis.

Question 2

What is a key step before insertion?

Accepted Answer

Hand hygiene and sterile technique

Answer

Before any invasive procedure like PICC insertion, meticulous hand hygiene and strict adherence to sterile technique are paramount. These practices prevent the introduction of microorganisms into the bloodstream during the procedure, significantly reducing the risk of catheter-related infections. Maintaining a sterile field and using appropriate personal protective equipment are critical components.

Question 3

How often should PICC dressings be changed?

Accepted Answer

Every 7 days or if soiled

Answer

Transparent semipermeable dressings used for PICC lines should typically be changed every 7 days to maintain a clean and secure site. However, if the dressing becomes soiled, damp, loose, or compromised in any way, it must be changed immediately. This proactive approach helps prevent bacterial colonization under the dressing and reduces the risk of infection.

Question 4

What solution is used to flush PICC lines?

Accepted Answer

Normal saline or heparin

Answer

To maintain patency and prevent occlusion of PICC lines, they are routinely flushed with either normal saline or a dilute heparin solution. Normal saline is used to clear medication residue and prevent intraluminal clotting, while heparin, an anticoagulant, is often used for catheters that are not in continuous use to prevent thrombus formation within the lumen. The specific solution depends on facility policy and catheter type.

Question 5

Why use ultrasound during insertion?

Accepted Answer

Visualize and guide vein access

Answer

Ultrasound guidance is a critical tool during PICC insertion as it allows the clinician to visualize the target vein in real-time. This visualization helps in identifying suitable veins, assessing their patency, and guiding the needle precisely into the vessel. Using ultrasound significantly increases insertion success rates and reduces the risk of complications like arterial puncture or nerve damage.
