Wikipedia
Extravasation is the leakage of intravenously (IV) infused potentially damaging medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices. When the leakage is not of harmful consequence it is known as infiltration. Extravasation of medication during intravenous therapy is an adverse event related to therapy that, depending on the medication, amount of exposure, and location, can potentially cause serious injury and permanent harm, such as tissue necrosis. Milder consequences of extravasation include irritation, characterized by symptoms of pain and inflammation, with the clinical signs of warmth, erythema, or tenderness.
__NOTOC__ Extravasation is the leakage of a fluid out of its container. In the case of inflammation, it refers to the movement of white blood cells from the capillaries to the tissues surrounding them ( leukocyte extravasation), also known as diapedesis. In the case of malignant cancer metastasis it refers to cancer cells exiting the capillaries and entering organs. It is frequently used in medical contexts, either referring to urine, or to blood.
More specifically, it can refer to:
- Extravasation (intravenous)
- Extravasation of infusates
- Extravasation of irrigation fluid
- Extravasation of urine
- Leukocyte extravasation
