Anticoagulation in intensive care medicine

Critically ill patients are at high risk of hemostasis disorders, which can be associated with both an increased risk of bleeding and an increased risk of thromboembolic events. In the case of acute vascular events, specific therapy with drug anticoagulation or platelet aggregation inhibition is essential. In patients with pre-existing conditions, the appropriate continuation of anticoagulation during intensive care treatment is important. Furthermore, in everyday clinical practice, prophylaxis of thromboembolism as well as the question of potential therapeutic options in the treatment of sepsis and infection-triggered disorders of blood coagulation are important. Specific questions arise with the use of extracorporeal devices such as renal replacement and circulatory assist systems. A number of new anticoagulation and anti-platelet drugs have become available in recent years. Laboratory monitoring of anticoagulation is central. In this overview, current aspects of these topics are presented.
