The Use Of Huber Needles

There are circumstances that arise when patients need to have a venous access available for such procedures as medications, blood products, drawing of blood, and total parenteral nutrition. Such illnesses as cancer, kidney disease, leukemia or problems that would require more than 6 weeks of venous access, may require the insertion of an implanted device. The venous access ports are surgically implanted in the chest and are accessed through the chest wall with a Huber needle.

The Huber needles are available in a variety of sizes to accommodate different patients. These Huber infusion sets are available from 19g x 3/4" size to 22g x 1" size. The needle set is latex free, so will not be a concern if a patient is admitted with a latex allergy. The fact they have a new needle hub and a wing design, offers greater security and accuracy when accessing the venous port site with the Huber needle. The set has an 11" micro bore tubing with a Y site, for when the patient is connected to infusions. This makes it more convenient for the patient and the nurses. These Huber needles come 25/box.

Always follow the protocol of the facility when using the implanted central port. Aseptic technique should always be used when caring for or accessing the venous port. The port should only be accessed by a registered nurse or physician. A Huber needle can be left in place for as long as 7 days after insertion, if there are no complications.

Prior to accessing the port with the Huber needle, always wash your hands with antibacterial soap and put on sterile medical gloves. Palpate the patient's chest in order to locate the needle port. Usually you can easily feel the port under the skin. Approximately the size of a quarter, the port will feel firm around the edges with a soft spongy center. After locating the port, follow the protocol of the facility, prepare a clean work area, prepare the Huber needle, clean the port site, insert the Huber needle and secure and cover the needle and site. Always document the gauge and length of the Huber needle used for access in the medical record.

One of the biggest benefits is that the implanted venous port allows for long term access and has the lowest incidence of blood borne infections. Although the port may have been inserted for the patient to receive chemotherapy, it can also be used for other things, such as antibiotics or blood. After use of the port is completed, remove the Huber needle per protocol. Again, always use sterile technique, flush the port per protocol, before you remove the needle.

The complications of the implanted port can include infiltration, skin breakdown, infection, occlusions, thrombus formation or catheter fracture. After assessing the port site, notify the physician and do not access the port if the site is red, tender, swelled or warm to touch.

The Huber needle is the only needle that is used to access the implanted venous port. Always check the site per facility protocol as long as the site is accessed with the Huber needle. Always use sterile technique when accessing or discontinuing a Huber needle, this cannot be stressed enough. The central venous implanted port allows the patient more freedom with daily life and is easy to maintain for hospital or home therapy.
