Brief Summary

Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep venous thrombosis (DVT), is a common and severe complication of critical illness. Critically ill patients are at high risk of VTE because they combine both general risk factors together with specific ICU risk factors of VTE. Vasopressor administration was found to be an independent risk factor for DVT. certainly explained by reduced absorption of subcutaneous heparin linked to the vasoconstriction of peripheral blood vessels. For critically ill patients, due to the altered pharmacokinetics behavior of unfractionated heparin, continuous intravenous infusion of the low doses of unfractionated heparin has been proposed. Standard prophylaxis with subcutaneous (SC) heparin is less efficient in patients requiring vasopressors. Sepsis is a systemic inflammatory response due to an infection. Both inflammatory mediators and coagulation are involved in sepsis. the release of inflammatory mediators such as interleukins and tumor necrosis factor causes damage to the endothelium and activation of coagulation which promotes the inflammatory process. Unfractionated heparin is the most negatively charged biological molecule known, heparin has a strong ability to interfere with the functioning of positively charged molecules. Due to the difference in charges, heparin has been documented to interact with over 100 proteins.57 Interleukins, cytokines, and receptors located on endothelial cells, which are involved in the acute phase response, are positively charged and thus are a reasonable target for the modulating effects of heparin. Heparin has strong anti-inflammatory effects with many possible mechanisms, including binding to cell-surface glycosaminoglycans, preventing leukocyte migration, direct binding to chemokines and cytokines, and inhibition of intracellular NF-kB.
