Which item is NOT typically added to a procedure tray?

In the context of a procedure tray used in interventional radiology, the primary purpose is to have all necessary items readily available for surgeons or interventional radiologists while performing a procedure. Items like catheters, gloves, and guidewires are essential components typically included on a procedure tray.

Catheters and guidewires are critical for accessing vascular pathways and facilitating various interventional procedures. They are used in a wide range of interventions such as placement of stents, embolization, and drainage procedures. Gloves, on the other hand, are fundamental for maintaining a sterile environment and protecting both the patient and the medical staff from infection and contamination during the procedure.

In contrast, hats are not a standard item included in a procedure tray. While personnel may wear surgical caps to maintain hygiene and minimize the risk of contamination, they are considered part of personal protective equipment (PPE) but are not directly utilized or required within the procedure itself for performing medical tasks. Therefore, hats do not belong on the procedure tray, distinguishing them from the essential tools and supplies needed to conduct interventional procedures safely and effectively.
