What happens when IV comes out of site and goes interstitial?

When an IV infiltrates and the fluid leaks into the interstitial space instead of remaining in the bloodstream, it can cause swelling, pain, and discomfort at the site. This condition, known as infiltration, may lead to tissue damage if the fluid is irritating or if the infiltration is extensive. Monitoring the site for signs of infiltration and promptly addressing it by stopping the IV and applying appropriate treatment is essential to prevent complications. In some cases, the IV may need to be relocated to ensure proper administration of fluids or medications.
