Early bleeding in leukemia patients is characterized by petechiae and occasionally petechiae on the skin throughout the body. Early bleeding in leukemia patients is often caused by a decrease in the platelet count. If the platelet count decreases further, there is an increase in bleeding. Bleeding from the gums, nasal bleeding, coughing up blood, gastrointestinal bleeding, and in more severe cases, bleeding from the fundus of the eye as well as brain bleeding can occur, and once brain bleeding occurs, the patient has a 100% mortality rate. For patients with leukemia who have bleeding, they need to monitor the blood routine and check the number of platelets. For patients with significantly decreased platelets, they need to actively apply for platelet transfusion support therapy to prevent rebleeding. For patients with extremely reduced platelets, multiple platelet transfusions can be requested at the same time.
