Which vein selection approach should be prioritized for IV insertion?

Choosing a distal site first for IV insertion is critical in maintaining vein availability for future access. By selecting a vein closer to the wrist or hand, the practitioner conserves proximal veins, which may be required later for additional intravenous therapy or for more complex procedures. This practice is particularly important in patients who may need multiple IV accesses or whose veins are difficult to puncture.

Prioritizing distal veins also ensures that larger, more robust veins in the upper arm or antecubital fossa remain available, allowing for successive procedures without compromising vascular access. This minimizes the risk of complications such as phlebitis or infiltration in the more distal sites, rendering the area unsuitable for future access.

While the size of the vein and visibility are important factors, they should take a back seat to the principle of site conservation when faced with multiple options. This approach not only benefits the patient in the long run but also reflects best practices in IV therapy.
