extravasation

 [eks-trav″ah-za´shun]
1. a discharge or escape, as of blood, from a vessel into the tissues.
2. the inadvertent administration of a vesicant into the tissues; the intensity of the irritating action is so severe that plasma escapes from the extracellular space and blisters are formed. Large extravasations of some medications may lead to contractures, with the need for débridement and grafting and in severe cases amputation. This term must be distinguished from intravenous infiltration and flare.
3. blood or another substance so discharged.

(eks-trav'ă-sā'shŭn),

[ikstrav′əsā′shən]
Etymology: L, extra + vas, vessel
1 a passage or escape into the tissues, usually of blood, serum, lymph or infusion. Compare bleeding.
2 passage or escape into tissue of antineoplastic chemotherapeutic drugs. Signs and symptoms may be sudden onset of localized pain at an injection site, sudden redness or extreme pallor at an injection site, or loss of blood return in an IV needle. Tissue slough and necrosis may occur if the condition is severe. Treatment depends on the causative agent. Nursing responsibilities include maintaining the patient IV line, elevating the affected area, applying ice packs, and notifying the physician of the need for antidote injections, if applicable.
