What does “extravasation” mean in the context of IV therapy?

In the context of IV therapy, "extravasation" specifically refers to the leakage of vesicant fluids into the surrounding tissue. Vesicant fluids are those that can cause tissue damage if they escape from the vein. This can lead to serious complications such as pain, swelling, and tissue necrosis, making it critical for healthcare providers to identify and manage extravasation promptly.

Understanding this term is essential for nurses and other healthcare professionals who administer IV therapy, as it emphasizes the importance of monitoring the IV site for any signs of leakage or complications. Recognizing the difference between extravasation and other issues, such as the formation of a blood clot or problems with IV line initiation, is crucial for patient safety and effective care.
