Where should the new needle be placed following an arterial needle infiltration?

Placing the new needle above or below the infiltrated site is essential to ensure proper blood flow during dialysis. When an infiltration occurs, it indicates that the needle has penetrated the vascular access site improperly, which can cause swelling and discomfort. By inserting the new needle above or below the infiltrated site, you avoid the compromised area and allow for effective puncture into healthy tissue, which minimizes discomfort for the patient and optimizes blood flow.

Using the same infected site could exacerbate the infiltration or lead to further complications. Similarly, placing the needle directly over the infiltrated area may not provide a viable access point either, as that area may still be compromised. While using a completely different limb may be necessary in some severe cases, it is typically not the first choice unless the infiltrated site is completely unsuitable for access. Thus, selecting a new site that is strategically located above or below the infiltration maximizes the likelihood of a successful and comfortable dialysis session.
