  2. Thrombocytopenia - Wikipedia

    en.wikipedia.org/wiki/Thrombocytopenia

    Low levels of platelets in turn may lead to prolonged or excessive bleeding. It is the most common coagulation disorder among intensive care patients and is seen in a fifth of medical patients and a third of surgical patients. [3] A normal human platelet count ranges from 150,000 to 450,000 platelets/microliter (μL) of blood. [4]

  3. Neonatal alloimmune thrombocytopenia - Wikipedia

    en.wikipedia.org/wiki/Neonatal_alloimmune...

    The diagnosis of NAIT is usually made after an incidental finding of a low platelet count on a blood test or because of bleeding complications ranging from bruising or petechiae to intracranial hemorrhage in the fetus or newborn. [6] Frequently, the reduction in platelet count is mild and the affected neonates remain largely asymptomatic. [6]

  4. Heparin-induced thrombocytopenia - Wikipedia

    en.wikipedia.org/wiki/Heparin-induced...

    This results in platelet activation and the formation of platelet microparticles, which initiate the formation of blood clots; the platelet count falls as a result, leading to thrombocytopenia. [1] [7] In addition, the reticuloendothelial system (mostly the spleen) removes the antibody-coated platelets, further contributing to the thrombocytopenia.

  5. Thrombotic thrombocytopenic purpura - Wikipedia

    en.wikipedia.org/wiki/Thrombotic...

    Thrombotic thrombocytopenic purpura (TTP) initially presents with a range of symptoms that may include severe thrombocytopenia (platelet count usually < 30,000/mm³), microangiopathic hemolytic anemia (evidenced by schistocytes in the blood smear), and various clinical signs such as petechiae, purpura, neurologic symptoms, myocardial ischemia ...

  6. Antiplatelet drug - Wikipedia

    en.wikipedia.org/wiki/Antiplatelet_drug

    Antiplatelet drugs effect may be affected by patient's medications, current medical conditions, food and supplements taken. Antiplatelet drugs effect may be increased or decreased. An increase in antiplatelet effect would increase the risk of bleeding and could cause prolonged or excessive bleeding.

  7. Disseminated intravascular coagulation - Wikipedia

    en.wikipedia.org/wiki/Disseminated_intravascular...

    Diagnosis is typically based on blood tests. [2] Findings may include low platelets, low fibrinogen, high INR, or high D-dimer. [2] Treatment is mainly directed towards the underlying condition. [2] [3] Other measures may include giving platelets, cryoprecipitate, or fresh frozen plasma. [2] Evidence to support these treatments, however, is ...

  8. Immune thrombocytopenic purpura - Wikipedia

    en.wikipedia.org/wiki/Immune_thrombocytopenic...

    Diagnosis of ITP involves identifying a low platelet count through a complete blood count, a common blood test. However, since the diagnosis relies on excluding other potential causes of a low platelet count, additional investigations, such as a bone marrow biopsy , may be necessary in certain cases.

  9. Platelet transfusion - Wikipedia

    en.wikipedia.org/wiki/Platelet_transfusion

    Higher platelet transfusion thresholds have been used in premature neonates, but this has been based on limited evidence. [19] There is now evidence that using a high platelet count threshold (50 x 10 9 /L) increases the risk of death or bleeding compared to a lower platelet count threshold (25 x 10 9 /L) in premature neonates. [20]
