If the needle infiltrates, what should be done first?

When a needle infiltrates during dialysis, stopping the blood pump immediately is the appropriate first action. This step is crucial because continued blood flow while the needle is infiltrated can cause further complications, such as tissue damage or other adverse effects in the surrounding area.

By stopping the blood pump, you prevent any additional blood from being drawn into the infiltrated tissue, which can help minimize swelling and discomfort for the patient. It's important to stabilize the situation before taking any additional steps, such as replacing the needle or notifying the physician. Addressing the immediate risk by halting the blood flow is vital in ensuring the patient's safety and well-being.
