    en.wikipedia.org/wiki/Thrombocytopenia

    Discontinuation of heparin is critical in a case of heparin-induced thrombocytopenia (HIT). Beyond that, however, clinicians generally treat to avoid thrombosis. [32] Treatment may include a direct thrombin inhibitor, such as lepirudin or argatroban. Other "blood thinners" sometimes used in this setting include bivalirudin and fondaparinux.

  5. Heparin - Wikipedia

    en.wikipedia.org/wiki/Heparin

    Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]

  6. Activated clotting time - Wikipedia

    en.wikipedia.org/wiki/Activated_clotting_time

    Activated clotting time (ACT), also known as activated coagulation time, is a test of coagulation. [1] [2]The ACT test can be used to monitor anticoagulation effects, such as from high-dose heparin before, during, and shortly after procedures that require intense anticoagulant administration, such as cardiac bypass, interventional cardiology, thrombolysis, extra-corporeal membrane oxygenation ...

  7. Thrombin time - Wikipedia

    en.wikipedia.org/wiki/Thrombin_time

    Batroxobin has a similar action to thrombin but unlike thrombin it is not inhibited by heparin, so reptilase time and thrombin time can be used concurrently to distinguish anticoagulant effect from hypofibrinogenemia or dysfibrinogenemia. [1] [5] Normal values for thrombin time may be 12 to 14 seconds, [6] but the test has significant reagent ...

  8. Low-molecular-weight heparin - Wikipedia

    en.wikipedia.org/wiki/Low-molecular-weight_heparin

    Smaller risk of heparin-induced thrombocytopenia, a potential side effect of heparin. Hepatin's anticoagulant effects are typically reversible with protamine sulfate, while protamine's effect on LMWH is limited. LMWH has less of an effect on thrombin than heparin, but about the same effect on Factor Xa.

  9. Medical calculator - Wikipedia

    en.wikipedia.org/wiki/Medical_calculator

    Medical calculators arose because modern medicine makes frequent use of scores and indices that put physicians' memory and calculation skills to the test. [2] The advent of personal computers, the Internet and Web, and more recently personal digital assistants (PDAs) have formed an environment conducive to their development, spread and use.
