The difference between leukemia nosebleed and ordinary bleeding is that the cause is different, the location is different, and the hemostatic method is different. 1. Different causes: Leukemia nosebleed is mainly caused by the decrease of platelet and hemostatic function of leukemia patients; common nosebleed is mainly caused by trauma. 2. Different location: Leukemia nosebleed is usually diffuse bleeding, it is difficult to find out the exact location; common nosebleed has a definite location, such as the front of nasal septum or nasopharynx. 3. Different methods of hemostasis: leukemia nosebleed should first find out the coagulation status of the body, if the platelet is too low, the coagulation mechanism decreases, first of all, should be given to stop bleeding (aminomethylenic acid) and at the same time increase the level of platelets (transfusion of platelet components, if necessary); ordinary nosebleed is mild can be naturally hemostatic. If the bleeding cannot be stopped naturally, sponge strips can be used to stop the bleeding. If the above symptoms occur, it is recommended to go to the hospital in time, first identify the cause of the nosebleed, and then under the guidance of the physician to carry out regular treatment as soon as possible.
