Molecular genetic details of the human coagulation system were among the first successes of the genetic revolution in the 1980s. This information led to new molecular diagnostic strategies for inherited disorders of hemostasis and the development of recombinant clotting factors for the treatment of the common inherited bleeding disorders. A longer term goal of this knowledge has been the establ...

introduction: acute traumatic coagulopathy (atc) is defined as having evidence of coagulopathy in patients with severe trauma. the aim of this preliminary study was to assess the prevalence and associated factors of atc in severely traumatic patients presenting to emergency department (ed). methods: in this retrospective cross sectional study, all patients with severe traumatic injury and avail...

Disorders of hemostasis and thrombosis are frequently encountered in the ICU setting. Understanding the relevance of laboratory findings is essential in providing appropriate therapy. Various blood products and hemostatic agents are available to assist in the control of bleeding, and several different classes of anticoagulants are now available for use. Appropriate use of these agents maximizes...

PURPOSE OF REVIEW To provide an overview of acquired coagulopathies that can occur in various perioperative clinical settings. Also described are coagulation disturbances linked to antithrombotic medications and currently available strategies to reverse their antithrombotic effects in situations of severe hemorrhage. RECENT FINDINGS Recent studies highlight the link between low fibrinogen and...

The process of haemostasis is complex and is further complicated in the parturient because of the physiological changes of pregnancy. Understanding these changes and the impact that they have on the safety profile of the anaesthetic options for labour and delivery is crucial to any anaesthetist caring for the parturient. This article analyses current theories on coagulation and reviews the phys...

Coagulation disorders concern a deficiency of the body’s functional ability to regulate blood clotting (Peyvandi and Mannucci, 1999). Disorders in thisarea, which may be genetic or acquired, will result in hemostasis-related problems, including different clinical syndromes from easy bleeding or bruising (so-called “hemophilia”) to inappropriate thrombosis (so-called “thrombophilia”; Weisberg, 1...

The development of inhibitory 'allo' antibodies to a deficient coagulation factor is arguably now the most severe and important complication of clotting factor concentrate exposure in haemophilia and other congenital coagulation disorders. Furthermore, development of an inhibitor to the factor VIII or factor IX transgene product remains a significant concern in gene therapy protocols for haemop...

PURPOSE OF REVIEW New data have been made available in the field of haemostasis and thrombosis. Some long-awaited answers to important questions have been published, and some debates have benefited from an updated perspective. RECENT FINDINGS Two important domains are addressed in this update: massive bleeding (1/1/1 ratios and fibrinogen concentrates) and the management of direct oral antico...

Coagulation and bleeding assume particular importance when operations are performed on the heart using extracorporeal circulation. This chapter begins with a discussion of the depth and breadth of hemostasis relating to cardiac procedures, beginning with coagulation pathophysiology. The pharmacology of heparin and protamine is described next. This background is then applied to treatment of the ...

Perioperative dilutional coagulopathy is a major coagulation disorder during adult and pediatric surgery. Although the main underlying mechanisms are comparable, data of the development and management of dilutional coagulopathy in children are scarce. Observational data showed that intraoperative coagulation disorders mainly based on complex disturbances of clot firmness including acquired fibr...
