The American College of Chest Physicians proposed guidelines for antithrombotic prophylaxis in patients with different risk factors, and it recommends that if the annual risk for thromboembolism is low, warfarin therapy can be withheld for 4-5 days before the procedure without bridging. Direct oral anticoagulants (DOACs) have expanded the armamentarium for antithrombotic therapy. For emergency surgery in patients who haven taken a new anticoagulant within a period less than that of its half-life, the use of the aforementioned antidotes (idarucizumab for dabigatran or andexanet alfa for factor Xa antagonists) can be considered for acute reversal of anticoagulation so that the surgical procedure can be performed with. In May 2018, Andexxa (coagulation factor Xa [recombinant], inactivated-zhzo or formerly andexanet alfa) received accelerated approval from the Food and Drug Administration (FDA) as a specific reversal for rivaroxaban- and apixaban-treated patients with life-threatening or uncontrolled bleeding despite not establishing improvement in hemostasis [].

(B) Andexanet alfa (And-α) is a modified inactive recombinant FXa that binds circulating FXa inhibitors, allowing native FXa to convert prothrombin to thrombin and restaure the coagulation cascade. Recent guidelines recommend resuming anticoagulation within 90 days if the patient is at moderate-high risk for VTE recurrence and the risk of recurrent bleeding is adequately low. Andexanet Alfa, which is a recombinant modified Factor Xa molecule, is currently being developed as an antidote for patients receiving a Factor Xa inhibitor who suffer a major bleeding episode.

It is a recombinant modified human factor Xa decoy protein that is catalytically inactive due to the substitution of the active-site serine with alanine. Deep Venous Thrombosis (DVT) DVT is the primary cause of pulmonary embolism. Apixaban is highly protein-bound; therefore, hemodialysis is ineffective. Idarucizumab is the treatment of choice for dabigatran-related life-threatening bleeding, while andexanet alfa is being developed to reverse factor Xa inhibitors. Mortality at discharge was 25%.

Risk for clinically relevant adverse cardiac events in patients with chest pain at hospital admission. Reversal agents for use with direct and indirect anticoagulants. As with the case series included in our meta-analysis, a controlled study is required to determine whether the reported rate of thromboembolic events exceeds the expected rate in patients who are already at increased risk of thromboembolic. Ciraparantag is a universal antidote targeted to reverse the direct thrombin and factor Xa inhibitors as well as the indirect inhibitor, enoxaparin. The ACCP Chest Guidelines have. Direct oral anticoagulants (DOACs) have been licensed worldwide for several years for various indications. Idarucizumab is the only commercially available agent. Michael Grant, a cardiac anesthesiologist at the Johns Hopkins University School of Medicine, to learn what we need to worry about (and what our pre-op evaluations should include) when our patients go off to cardiac surgery.
