When the nephrologist orders a 16 gauge needle and a 400 BFR, what should you do?

When the nephrologist orders a 16 gauge needle and a blood flow rate (BFR) of 400, it is important to assess the compatibility and safety of the equipment being used. The preferred practice in this situation is to utilize a 15 gauge needle. This recommendation is based on the fact that a 15 gauge needle can better accommodate the flow requirements of 400 BFR while ensuring optimal patient safety and efficiency during the procedure.

Choosing to suggest a 15 gauge needle takes into account the balance between the gauge size and the necessary blood flow rate. Improper gauge selection can lead to complications such as insufficient blood flow or even damage to the patient's vascular access, which emphasizes the need for careful adherence to guidelines.

In this context, considering options involving insertion of needles without consulting or using other sizes such as 14 gauge may not align with established protocols and standards intended for patient safety and procedural accuracy. Therefore, advocating for an adjustment to a 15 gauge needle supports both the practical requirements of the procedure and the best practices in patient care.
