What indicates that a PIV should not be used?

The presence of a fracture in the arm is a clear indication that a peripheral intravenous (PIV) catheter should not be used in that location. When a fracture is present, using a PIV could exacerbate pain, increase the risk of complications, and hinder the healing process. This is particularly important because inserting a catheter in an area with compromised structural integrity can lead to further injury or complications like increased swelling or infection.

In general, PIV catheters are utilized in areas where the vascular system is intact and accessible. Other factors, such as the duration of therapy, the type of substances being infused, or a short pulse rate, do not inherently indicate the inappropriateness of using a PIV. For example, therapy lasting less than six days typically aligns with the use of a PIV. Likewise, non-irritant medications can typically be administered safely via PIV. Thus, choosing a site free from any anatomical or structural concerns, such as a fracture, is critical for safe and effective vascular access.
