Understanding the Difference Between Short-Term and Long-Term Hemodialysis Catheters

2024-09-20

Hemodialysis is a life-saving treatment for patients with severe kidney failure, where a machine filters waste products and excess fluids from the blood.

The process requires access to the patient's bloodstream, which is achieved through the use of hemodialysis catheters. Depending on the duration and

frequency of the treatment, two types of catheters are commonly used: short-term and long-term hemodialysis catheters. Understanding the

differences between these two types is crucial for proper patient management and treatment planning.


Short-Term Hemodialysis Catheters

Short-term hemodialysis catheters, also known as temporary or acute catheters, are designed for immediate but temporary use. They are typically

placed in situations where urgent hemodialysis is required, such as in patients with acute kidney injury, who have not yet had a permanent vascular

access established, or when a long-term catheter becomes dysfunctional or infected.


Characteristics:

1. Placement and Duration: These catheters are usually inserted into large central veins, such as the internal jugular, femoral, or subclavian veins. The

placement is typically guided by ultrasound to minimize complications. They are intended for use over a short period, generally less than three weeks.


2. Material and Design: Short-term catheters are made from soft, flexible materials like polyurethane. They have a dual-lumen design, allowing for

efficient blood flow during dialysis sessions.


3. Advantages: The primary advantage of short-term catheters is their rapid insertion and removal. They are ideal for emergency situations where

immediate dialysis is needed, as they can be used almost immediately after insertion.


4. Disadvantages: These catheters have a higher risk of complications, such as infection and clotting, due to their external positioning and the lack of

tissue ingrowth. They are also not suitable for long-term use due to the potential for vein damage.


Long-Term Hemodialysis Catheters

Long-term hemodialysis catheters, also referred to as tunneled or chronic catheters, are designed for patients who require ongoing dialysis treatment

but cannot use other forms of vascular access, like an arteriovenous (AV) fistula or graft. They are often used for patients awaiting the maturation of an

AV fistula or as a permanent solution when other options are not viable.


Characteristics:

1. Placement and Duration: These catheters are surgically inserted into a large vein, typically the internal jugular vein, and tunneled under the skin to an

exit site on the chest. This tunneling reduces the risk of infection by creating a barrier between the external environment and the bloodstream. They are

intended for use over several weeks to months, and sometimes even years, depending on patient needs.


2. Material and Design: Long-term catheters are usually made from durable materials like silicone and have a larger diameter compared to short-term

catheters. The design often includes a Dacron cuff, which encourages tissue growth to secure the catheter and reduce infection risk.


3. Advantages: The key advantage of long-term catheters is their suitability for extended use. They offer a more stable and safer option for chronic

dialysis patients, with a reduced risk of dislodgment and infection due to the tunneled design.


4. Disadvantages: Despite their advantages, long-term catheters are still more prone to complications compared to AV fistulas or grafts. They can

become infected or clotted, and their insertion is more complex, requiring surgical intervention.


Choosing the Right Hemodialysis Catheter


The choice between short-term and long-term hemodialysis catheters depends on the patient's condition and the expected duration of treatment.

Short-term catheters are ideal for immediate or temporary access, while long-term catheters provide a more durable solution for patients requiring

prolonged dialysis. Healthcare providers must evaluate the risks and benefits of each type to ensure optimal patient care.
