Treatment for breast cancer involves needles, and that means you will get stuck with syringes, IV needles, butterfly needles, and Huber needles. Don't panic the first time you see that long, curved chemo needle - it is designed to make treatment easier on you. Learn how to prevent the sting of a needle stick, know the size of needle you need, and how the Huber needle is safer for you and your nurse.
A Huber is a specially designed hollow needle used with implanted ports. A Huber needle has a long, beveled tip that can go through your skin as well as the silicone septum of your implanted port's reservoir. The beveled tip of a Huber needle will not remove a core of silicone from your port – this prevents a chunk of silicone or skin from lodging in your catheter line and makes your port last longer. Dr. Ralph L. Huber, a dentist, designed the sharp, beveled, directional needle tip and Dr. Edward B. Tuohy, an anesthesiologist, refined it for use in spinal catheters.
Huber needles are hard at work in several settings. These needles can be used for an infusion appointment to give chemotherapy, antibiotics, saline fluid, or blood transfusions. Huber needles may by left in place for a few hours or over several days if needed. Many patients benefit from Huber needles – these are used in dialysis, lap-band adjustments, blood transfusions, and intravenous cancer treatments.

Huber needles come in several lengths and gauges. You should know the size of needle that works with your port. If your nurse uses a Huber needle that is too short, it won't work well for your blood draw or your infusion. I found that a short, curved Huber pushed into my arm port was painful and tight, and usually had to be replaced. Likewise, a Huber needle that is too long for your port might wobble or spin around, causing damage to the silicone seal. Most infusion nurses will secure a Huber needle and catheter set in place with tape or an occlusive bandage.
Needles, like infusion ports, come in different sizes. Infusion needles should be sized to match the type of implanted port that you have. Huber needles come in 0.5" up to 1.5" lengths for use with infusion ports. These needles are usually color-coded and come in different diameters; 21 - 25 gauge. Ask your blood nurse or infusion nurse for the length and gauge of Huber needle that works best with your port. Keep this information in your health notebook. If you visit a different clinic or hospital, this information may save you some pain and prevent multiple needle sticks.
A Huber needle must be used to access your chemo port. The strong, tapered point of a Huber will be less painful than a non-tapered needle, and will slice through skin and silicone cleanly. This type of needle does not remove a core of skin or silicone, so your port will reseal itself, and your skin will heal neatly when the needle is withdrawn. But if you do need to prevent the pain of a needle stick, use some "scream cream" – a term nurses often use for Lidocaine gel or Emla cream. Once your needle is in place in your port, don't rock or twist it, because that will damage the silicone septum.
Intravenous chemotherapy is given through a needle and catheter, which must be removed at the end of treatment. The needle is in contact with your chemo drugs and your blood supply. In order to prevent infections and accidental needle sticks, there are safety devices designed for use with these needles. The plastic wings and needle guards on your Huber needle protect you and your nurse from injury and infection. After use, the needles will be safely disposed of, along with medical waste. You will have a bandage over your needle puncture after treatment – be sure to keep it on 15-30 minutes after your infusion, to keep the area clean and prevent leaks.
