fondaparinux and Multiple-Organ-Failure

Disseminated intravascular coagulation (DIC) is the physiologic result of pathologic overstimulation of the coagulation system. Despite multiple triggers, a myriad of laboratory abnormalities, and a clinical presentation ranging from gross hemostatic failure to life-threatening thrombosis, or even both simultaneously, a simplified clinical approach augmented by a few readily available tests allows prompt identification of the process and elucidation of treatment opportunities. Platelet counts in DIC may be low, especially in acute sepsis-associated DIC, yet increased in malignancy-associated chronic DIC. Thrombotic risk is not a function of the platelet count, and thrombocytopenia does not protect the patient from thrombosis. The stratification of both thrombotic risk and hemorrhagic risk will be addressed.

For patients with heparin-induced thrombocytopenia (HIT), reexposure to heparin is generally not recommended. However, these patients are likely to require anticoagulation therapy at some point in the future. During acute HIT, when thrombocytopenia and anti-heparin-platelet factor 4 antibodies (or HIT antibodies) are present, therapy with heparin must be avoided. In patients with subacute HIT, when platelets have recovered but HIT antibodies are still present, therapy with heparin should be avoided. In patients with a remote history of HIT, when HIT antibodies have cleared, heparin reexposure may be safe, although recurrent HIT has been described in some patients. For all of these patients, the use of alternate anticoagulant agents, including direct thrombin inhibitors and anti-Xa agents, is preferable. There is an increasing amount of data supporting the use of these alternative agents in a wide variety of clinical circumstances, including thromboprophylaxis and treatment of acute thrombosis. Except for a few clinical situations, it is generally possible to avoid heparin reexposure in patients with a history of HIT.

To compare the effects and side-effects of fondaparinux sodium and low molecular weight heparin in patients with hypercoagulability accompanied with traumatic infection.. Thirty-six patients with post-traumatic infections in our hospital intensive care center were diagnosed with hypercoagulability from February 2012 to February 2013. These patients were randomly divided into 2 groups. In group F (18 patients), the patients were treated with fondaparinux sodium, 2.5 mg, 1/d for 11 d. In group L (18 patients), the patients were treated with low molecular weight heparin, 4100 U, 1/12 h for 11 d. The incidence of deep vein thrombosis, bleeding events and multiple organ dysfunction syndrome (MODS) and mortality of two groups after anticoagulation therapy were analyzed. Fibrinogen, D-dimer level and activity of antithrombin III were measured by the coagulation analyzer.. The incidence of deep vein thrombosis, MODS incidence and mortality were not significantly different between the two groups. The rate of bleeding evens in group F was lower than group L (p < 0.05). Antithrombin III got an upward trend after anticoagulant therapy, in which it was higher in group F than in group L on the 5th d and 11th d (p<0.05). Fibrinogen levels were gradually increased, and there was no significant difference between two groups (p>0.05). D-dimer was significantly decreased after anticoagulant therapy for 5 d (p<0.01), and there were significant differences between two groups on the 5th d and 7th d (p<0.05). It showed no significant difference on the 11th d (p>0.05).. Fondaparinux sodium and low molecular weight heparin can effectively improve coagulopathy in patients with traumatic infection. Compared with low molecular weight heparin, fondaparinux sodium may reduce the risk of bleeding events in patients with hypercoagulability accompanied by traumatic infection.
