There is not much progress in the latest treatment of hemophilia, but mainly conventional treatment methods, such as prophylactic treatment, targeted protein s, supplementation of coagulation factors, and mastery of hemostasis methods. 1. Preventive treatment: Adopt quiet living habits from childhood and avoid staying up late, so as to reduce the risk of cerebral hemorrhage. 2. Targeted proteins: Avoid intramuscular injections as much as possible, and use targeted proteins to help patients improve their coagulation function when they have surgical diseases that require surgery. 3. Supplementation of coagulation factors: When suffering from coagulopathy, we should actively supplement the coagulation factors needed by the body to reduce the risk of bleeding and shorten the time of hemostasis after bleeding. 4. Mastering hemostatic methods: Mastering some local hemostatic methods for the oral cavity, nasal cavity, surface trauma for local compression hemostasis or fibrin foam dressing, you can also choose to use gauze dipped in tissue thromboplastin placed in the wound location to assist in hemostasis. Hemophiliacs are advised to go to the hospital for regular checkups, specific diagnosis and treatment under the guidance of a physician.
