What does infiltration refer to in the context of IV therapy?

Infiltration in the context of IV therapy specifically refers to the unwanted leakage of nonvesicant IV fluid from the vein into the surrounding extravascular tissues. This can occur when the IV catheter becomes dislodged or when the vein wall is compromised, allowing the fluid intended for intravenous administration to seep into the tissue rather than remain within the vascular system.

Recognizing this is crucial for nurses and healthcare providers, as infiltration can lead to swelling, discomfort, and tissue damage if not addressed promptly. Management typically involves stopping the infusion at the site, removing the IV catheter, and evaluating the affected area for any complications.

Other options refer to different conditions or complications associated with IV therapy. Leakage of vesicant fluids could lead to more severe tissue damage and is a separate concern altogether. Air bubbles in the IV line suggest issues with air embolism or improper line setup, while inflammation of the IV site usually indicates phlebitis or infection rather than infiltration. Understanding the distinction between these terms is essential for proper IV therapy management and patient safety.
