Extravasation is the leakage of intravenously (IV) infused, and 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.
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).
A blister agent (or vesicant), is a chemical compound that causes severe skin, eye and mucosal pain and irritation. They are named for their ability to cause severe chemical burns , resulting in painful water blisters on the bodies of those affected.
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 ...
Angiopellosis allows for the extravasation of multiple cells during a single event. The blood vessel will actively remodel around a cluster/group of cells and allow the cells to exit in a single event. Diapedesis only allows for a single white blood cell to migrate across the blood vessel wall at a given time.
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
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.
Most nettle agents, such as the best known and studied nettle agent, phosgene oxime, are often grouped with the vesicant (blister agent) chemical agents. However, because nettle agents do not cause blisters , they are not true vesicants.
