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.
The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin calor, dolor, rubor, tumor, and functio laesa). Inflammation is a generic response, and therefore is considered a mechanism of innate immunity , whereas adaptive immunity is specific to each pathogen.
Immune complexes form in the setting of high local concentration of vaccine antigens and high circulating antibody concentration. Arthus reactions are characterized by severe pain, swelling, induration, edema, hemorrhage, and occasionally by necrosis. These symptoms and signs usually occur 4–12 hours after vaccination.
A site with signs of infection or muscle atrophy should not be chosen. Intramuscular injections should not be used in people with myopathies or those with trouble clotting. Intramuscular injections commonly result in pain, redness, and swelling or inflammation around the injection site. These side effects are generally mild and last no more ...
The symptoms of TACO can include shortness of breath , low blood oxygen levels , leg swelling (peripheral edema), high blood pressure (hypertension), and a high heart rate (tachycardia). [ 3 ] It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [ 2 ]
