What additional item would be added to a procedure tray?

In the context of interventional radiology, access needles are critical instruments that facilitate the entry of the interventionalist into the vascular system or other specified areas within the body during a procedure. These specialized needles are essential for the initial step of accessing blood vessels or other structures to perform various diagnostic or therapeutic interventions, such as catheter placements, biopsies, or ablations.

Adding access needles to a procedure tray ensures that all necessary tools are readily available and prepared for use during the intervention. This minimizes delays and enhances the efficiency of the procedure, supporting patient safety and care continuity. Access needles are particularly designed for this purpose, which is why they stand out as a logical addition to a procedural setup in interventional radiology.

The other items listed may not be specifically necessary for every procedure. Surgical drapes are used for maintaining a sterile field, bandages are primarily for post-procedural care, and patient monitors, while essential for overall patient safety during procedures, are typically separate from the instruments contained in a procedure tray. Hence, access needles are the most relevant and crucial item to include; they directly support the hands-on aspects of the procedure itself.
