Acute normovolemic hemodilution (ANH) is a form of autologous transfusion where whole blood is collected from a patient at the start of surgery into a standard blood collection bag with anticoagulant with the simultaneous replacement of intracellular volume using acellular fluids (such as normal saline).
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes , which help keep the bite area unclotted long enough for the animal to obtain blood.
They found that the mixture offers better red blood cell survival than the then state-of-the-art, MRC 1940 (trisodium citrate plus glucose). The old solution also caramelize when autoclaved, while the new one does not due to higher acidity. [3] As a result, blood can now be stored for much longer, up to 21 days. [4]
Direct thrombin inhibitors (DTIs) are a class of anticoagulant drugs that can be used to prevent and treat embolisms and blood clots caused by various diseases. They inhibit thrombin, a serine protease which affects the coagulation cascade in many ways. DTIs have undergone rapid development since the 90's.
Posterior abdominal wall, after removal of the peritoneum, showing kidneys, suprarenal capsules, and great vessels. (Hepatic veins labeled at center top.) Any obstruction of the venous vasculature of the liver is referred to as Budd–Chiari syndrome, [19] from the venules to the right atrium. This leads to increased portal vein and hepatic ...
Plasmapheresis (from the Greek πλάσμα, plasma, something molded, and ἀφαίρεσις aphairesis, taking away) is the removal, treatment, and return or exchange of blood plasma or components thereof from and to the blood circulation. It is thus an extracorporeal therapy, a medical procedure performed outside the body. [citation needed]
[1] [2] Antithrombotics can be used therapeutically for prevention (primary prevention, secondary prevention) or treatment of a dangerous blood clot (acute thrombus). In the U.S., the American College of Chest Physicians publishes clinical guidelines for clinicians for the use of these drugs to treat and prevent a variety of diseases.
Low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. [1] They are used in the prevention of blood clots and, in the treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism), and the treatment of myocardial infarction.
