Infant thrombocytopenia does not necessarily require transfusion of C-globulin, infant thrombocytopenia needs to be treated for the cause. If there is serious bleeding in infants with thrombocytopenia, including gastrointestinal bleeding, cerebral hemorrhage, urinary bleeding, when the bleeding is more extensive, can be transfused gammaglobulin treatment, which can significantly and rapidly increase the number of platelets. Infant thrombocytopenia without severe bleeding is not necessary to transfuse C-globulin treatment, and frequent transfusion of C-globulin treatment will also produce adverse reactions, such as rash, diarrhea and so on. In addition, Procalcitonin is contraindicated in patients with severe hepatic or renal impairment and hypersensitivity to the product. Thrombocytopenia in infants can be caused by infection, immunity, tumor, leukemia, etc. Like infection-induced thrombocytopenia in infants, it can be treated by anti-infection treatment with drugs such as ribavirin, and the platelet count can rise after the infection is controlled. The use of medication should be guided by a doctor. Parents are advised to bring their infants to regular hospitals in time when they find thrombocytopenia in infants, so that doctors can determine the treatment plan.
