Tunneled Catheter vs. Non-Tunneled Catheter: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 27, 2024
Tunneled Catheter is a catheter inserted into a vein with a portion tunneled under the skin to reduce infection risk. Non-Tunneled Catheter is a catheter directly inserted into a vein without subcutaneous tunneling, used for short-term access.
Key Differences
A Tunneled Catheter is distinct in its design, featuring a portion that is tunneled under the skin, thereby reducing the risk of infection. This contrasts with a Non-Tunneled Catheter, which is directly inserted into a vein without this subcutaneous tunneling, often used for immediate or short-term vascular access.
The insertion process of a Tunneled Catheter is more complex and typically done in a surgical setting, providing long-term access. On the other hand, Non-Tunneled Catheters are simpler to insert, often in emergency or acute care settings, reflecting their utility for short-term use.
Maintenance and care differ between the two: Tunneled Catheters often require less frequent site care due to their design minimizing infection risks. Conversely, Non-Tunneled Catheters, being more exposed, need more rigorous and regular site care to prevent infections.
In terms of applications, Tunneled Catheters are typically used for long-term treatments like chemotherapy, requiring stable and secure venous access. Non-Tunneled Catheters are more common in acute hospital settings for quick administration of medications or fluids.
The removal process varies: removing a Tunneled Catheter often requires a small procedure due to its under-skin tunneling, whereas Non-Tunneled Catheters can be removed simply and swiftly, aligning with their short-term application.

Tunneled Catheter and Non-Tunneled Catheter Definitions
Tunneled Catheter
A catheter involving a surgical procedure for placement.
Surgical placement of the tunneled catheter was scheduled for today.
Non-Tunneled Catheter
A catheter designed for short-term vascular access, often used in emergencies.
In the ER, a non-tunneled catheter was quickly placed for the treatment.
Tunneled Catheter
A catheter designed for long-term use with a part tunneled beneath the skin.
The patient received a tunneled catheter for ongoing chemotherapy.
Non-Tunneled Catheter
A catheter suitable for acute care and short-term treatments.
For his brief hospital stay, a non-tunneled catheter was sufficient.
Tunneled Catheter
Used for stable, long-term vascular access, particularly in chronic conditions.
Tunneled catheters are ideal for patients requiring long-term IV medications.
Non-Tunneled Catheter
A catheter inserted directly into a vein for immediate use.
They used a non-tunneled catheter for the urgent IV fluid administration.
Tunneled Catheter
A catheter preferred for treatments where frequent access to a vein is needed.
For his dialysis, a tunneled catheter was chosen for easier vein access.
Non-Tunneled Catheter
A catheter that can be inserted without the need for a surgical procedure.
The nurse inserted the non-tunneled catheter without needing surgery.
Tunneled Catheter
A catheter that reduces infection risk through its subcutaneous tunnel.
Her tunneled catheter's design minimizes the risk of infection.
Non-Tunneled Catheter
A catheter with a higher risk of infection due to its direct insertion method.
Due to its nature, the non-tunneled catheter required vigilant site care.
FAQs
How is a Non-Tunneled Catheter inserted?
It is directly placed into a vein, usually in an acute care setting.
How does a Tunneled Catheter reduce infection risk?
Its under-skin tunneling shields it from direct exposure to pathogens.
What is the primary use of a Tunneled Catheter?
For long-term treatments like chemotherapy or chronic IV therapy.
Why is a Non-Tunneled Catheter more prone to infections?
Its direct and external placement makes it more exposed to infection risks.
What is a Non-Tunneled Catheter?
A catheter directly inserted into a vein, used for short-term vascular access.
What is the primary use of a Non-Tunneled Catheter?
For short-term or emergency treatments requiring immediate vein access.
How is a Tunneled Catheter inserted?
Through a minor surgical procedure, part of it is tunneled beneath the skin.
Is a Non-Tunneled Catheter suitable for long-term use?
No, it's primarily intended for short-term or immediate use.
Is surgical removal required for a Tunneled Catheter?
Yes, a small procedure is often needed due to its under-skin tunneling.
What is a Tunneled Catheter?
A long-term use catheter with a portion tunneled under the skin to reduce infection risks.
Can a Tunneled Catheter be used for emergency treatments?

Are Tunneled Catheters used in dialysis?
Yes, they're often used in dialysis for stable, long-term vein access.
How often does a Non-Tunneled Catheter need site care?
Regularly, to prevent infections due to its direct vein exposure.
Can a Non-Tunneled Catheter be easily removed?
Yes, it can be quickly and easily removed as it's not tunneled.
How often does a Tunneled Catheter need site care?
Less frequently, due to its design minimizing infection risks.
Are Non-Tunneled Catheters used for fluid resuscitation?
Yes, they're commonly used for quick fluid administration in acute care.
What is the durability of a Tunneled Catheter?
They're designed to be durable for extended periods of use.
Is a Non-Tunneled Catheter durable for long-term use?
No, they're not designed for durability beyond short-term treatment.
