In the event of poor coagulation function, blood routine and coagulation function tests should be carried out first, and if necessary, bone marrow examination should be carried out to clarify the cause of poor coagulation function, and then targeted treatment should be carried out.

1. Thrombocytopenia
Essential thrombocytopenia is an autoimmune disease that requires the use of glucocorticoids, gamma globulin for immunosuppressive therapy, and the use of androgens to promote hematopoiesis. Thrombocytopenia due to hypersplenism requires splenectomy. If thrombocytopenia is severe, activity restriction is required, and platelet transfusions reduce severe bleeding.

2. Coagulation factor deficiency
Hemophilia is a hereditary bleeding disease. The body cannot synthesize coagulation factors 8 and 9, and bleeding is prone to occur. However, there is still no cure for it, and only coagulation factors can be supplemented for replacement therapy. Various types of hepatitis, liver cirrhosis, liver cancer and other liver functions are damaged and cannot synthesize enough coagulation factors, so liver protection treatment is required. If vitamin K is deficient, bleeding will also occur, and exogenous vitamin K supplementation is required to reduce the risk of bleeding.

3. Increased permeability of blood vessel walls
The increase in the permeability of the blood vessel wall caused by various reasons will also affect the coagulation function. It is necessary to take drugs such as vitamin C to improve the permeability of the blood vessels.
