This paper reports a case of thrombocytopenia in a child who caused spontaneous tonsillar hemorrhage and severe epistaxis successively. The child, 5 years and 8 months old, was admitted to the hospital for the first time because of "intermittent vomiting of blood for 2 days", the second time for "repeated bleeding in the left nasal cavity for 1 day", and the third time for "repeated bleeding in the left nasal cavity for 3 hours". "See a doctor. The treatment measures and effects of the 3 bleeding events were reviewed and analyzed, and it was found that there were similarities and differences in the treatment principles of the 2 bleeding events. In the treatment of spontaneous tonsil hemorrhage caused by thrombocytopenia, local compression, hemostatic drugs and transfusion of platelets are not effective in controlling bleeding, and surgical hemostasis is effective; when platelet weakness causes epistaxis, surgery needs to be handled carefully, and front and rear nostril packing should be administered at the same time. Systemic therapy is an effective approach to control bleeding. After treatment, the child was discharged from the hospital without any further bleeding.
