For patients with thrombocytopenia, the treatment is as follows: First, in the diet should eat more fresh fruits and vegetables, but also eat high-quality protein, such as eggs, meat, fish, etc., because the blood-forming materials are abundant, the number of platelets will also be elevated. Second, if the platelets are raised quickly, the most effective way is to transfuse platelets, by transfusing someone else’s platelets into the patient, the platelets can be raised quickly, often applied to patients with severely reduced platelets complicated by severe bleeding or who need surgery. Third, the application of interleukin-11 to raise platelets, which is a drug that stimulates the proliferation of megakaryocytes, can stimulate the proliferation of megakaryocytes and rapidly raise platelets. However, for elderly patients, interleukin-11 should be used to prevent the occurrence of cardiac arrhythmia. Fourth, recombinant human angiopoietin can be applied to raise platelets, which is a safe and effective method to raise platelets, and can promote the proliferation of megakaryocytes to raise peripheral blood platelets.
