1. Introduction: What Is a Huber Needle?

A Huber needle, also known as a non-coring Huber needle, is a specialized medical device designed for safe and repeated access to implantable ports used in

chemotherapy and long-term treatments. Unlike traditional needles, a Huber needle features a curved or angled tip that prevents coring — the removal of small pieces of

the silicone septum in a port. This design extends the life of the port and minimizes complications.

Huber needles are essential components of vascular access systems for patients undergoing chemotherapy, total parenteral nutrition, or frequent blood draws and

infusions.

2. Huber Needle for Chemotherapy: Essential for Port Access

Chemotherapy often requires the administration of powerful drugs over extended periods. To avoid frequent needle sticks and reduce vein damage, patients typically

receive an implantable port — a small medical device placed under the skin, usually in the chest. A Huber needle is the recommended device for accessing this port.

Because it is non-coring, the Huber needle safely penetrates the silicone septum of the port without damaging it, ensuring that the port remains functional for months or

even years. This makes the Huber needle an essential tool in the daily care of chemotherapy patients.

3. Benefits of Huber Needles for Chemotherapy

Using a Huber needle for chemotherapy offers several clinical and patient-centered benefits:

Minimized Port Damage: The non-coring design preserves the integrity of the implantable port, reducing the risk of leakage or malfunction.

Reduced Infection Risk: Huber needles are often used with sterile dressings and closed systems that help reduce catheter-related bloodstream infections.

Enhanced Patient Comfort: The needle is designed for repeated use over multiple days, reducing the frequency of needle insertions.

Secure Vascular Access: Provides a stable and reliable connection for high-dose chemotherapy drugs that require precise delivery.

Cost-Effective: Preserving the life of the port helps reduce the need for replacements or additional surgeries.

4. How Long Can You Leave a Huber Needle in a Port?

The dwell time of a Huber needle depends on the treatment plan and institutional protocols, but in general, a Huber needle can remain in place for up to 7 days if

managed properly with sterile dressings and regular flushing.

Nurses and clinicians must monitor the insertion site for signs of infection, irritation, or displacement. Prolonged use beyond the recommended period may increase the

risk of infection or phlebitis, so timely huber needle removal and reinsertion are necessary during long-term chemotherapy.

5. Huber Needle Insertion: Best Practices

Proper huber needle insertion is critical for both patient safety and the longevity of the port system. Here's a basic overview of the process:

1. Preparation: Wash hands, don sterile gloves, and gather supplies, including the Huber needle set, sterile dressing, and antiseptic.

2. Site Cleaning: Clean the skin over the port site thoroughly using an antiseptic agent like chlorhexidine.

3. Needle Insertion: Align the Huber needle with the center of the port and insert it at a 90-degree angle until it makes full contact with the port base.

4. Verification: Confirm placement by aspirating for blood return and flushing with saline.

5. Secure the Needle: Apply a sterile transparent dressing to keep the needle stable.

Training and experience are essential, as improper insertion can damage the port or cause complications such as infiltration or infection.

6. Huber Needle Removal and Aftercare

Huber needle removal is a straightforward but sterile procedure. It should be done by trained personnel to prevent contamination or trauma to the port site.

Steps include:

1. Stop Infusion: Turn off any active IV lines connected to the Huber needle.

2. Flush the Port: Flush with normal saline and heparin (if required) to maintain patency.

3. Remove the Dressing: Carefully peel off the sterile dressing while stabilizing the needle.

4. Withdraw the Needle: Gently and steadily remove the needle from the port.

5. Apply Pressure and Bandage: Use a sterile gauze pad to apply pressure, then cover the site with a fresh dressing.

After removal, the site should be monitored for redness, swelling, or signs of infection.

Conclusion

The Huber needle plays a vital role in chemotherapy and long-term vascular access by offering a safe, efficient, and patient-friendly solution for accessing implantable

ports. Its non-coring design not only preserves the integrity of the port but also enhances comfort and reduces the risk of complications.

Whether for infusion, blood draw, or medication delivery, understanding the correct huber needle insertion and removal techniques is essential for healthcare providers.

For patients, knowing the importance of Huber needles can help them feel more confident and informed during their chemotherapy journey.
