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.
Infiltration is one of the most common adverse effects of IV therapy [52] and is usually not serious unless the infiltrated fluid is a medication damaging to the surrounding tissue, most commonly a vesicant or chemotherapeutic agent. In such cases, the infiltration is termed extravasation, and may cause necrosis. [53]
Infiltration is the diffusion or accumulation (in a tissue or cells) of foreign substances in amounts excess of the normal. The material collected in those tissues or cells is called infiltrate . Definitions of infiltration
Extravasation of intravenous sodium bicarbonate has been reported to cause chemical cellulitis because of its alkalinity, resulting in tissue necrosis, ulceration and/or sloughing at the site of infiltration. This condition is managed by prompt elevation of the part, warmth and local injection of lidocaine or hyaluronidase.
Intravenous injections may also cause phlebitis, especially when multiple injections are given in a vein over a short period of time. [40] Infiltration and extravasation may also occur when a medication intended to be injected into a vein is inadvertently injected into surrounding tissues. [ 41 ]
Extravasation of irrigation fluid is the unintended migration of irrigation fluid (e.g., saline) introduced into a human body.This may occur in several types of endoscopic surgery, such as minimally invasive orthopedic surgery, i.e., arthroscopy, TURP (trans-urethral resection of the prostate), and TCRE (trans-cervical resection of the endometrium).
Venous access is any method used to access the bloodstream through the veins, either to administer intravenous therapy (e.g. medication, fluid), parenteral nutrition, to obtain blood for analysis, or to provide an access point for blood-based treatments such as dialysis or apheresis.
Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response.. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the circulatory system (extravasation) and towards the ...
