Know the Difference: Infiltration vs. Extravasation

Intravenous infiltration is one of the most common problems that can occur when fluid infuses into the tissues surrounding the venipuncture site. This sometimes happens when the tip of the catheter slips out of the vein or the catheter passes through the wall of the vein. If you are concerned an IV is infiltrated, standard procedures should be followed by, for example, discontinuing the site and relocating the IV. An extravasation occurs when there is accidental infiltration of a vesicant or chemotherapeutic drug into the surrounding intravenous site. Vesicants can cause tissue destruction and / or blistering. Irritants can result in pain at the site and along the vein and may cause inflammation. The treatment for extravasation will vary depending on hospital policy.
