The absorption time of intracranial hematoma needs to be judged according to the cause of bleeding, the size and location of the hematoma volume and the degree of concurrent injury. If the vascular injury is relatively small and the bleeding volume is relatively small, the absorption time will be short. If the vascular injury is relatively large, and the bleeding volume is relatively large, the absorption time will be longer, and even craniotomy will be required for hematoma removal. For intracranial hematomas that do not reach the indication of surgery, absorption can be seen within 1 week and can be observed dynamically, and most hematomas are basically absorbed within 1 month. When an intracranial hematoma is found, medical staff should be alert and take certain measures to sedate the patient and not to make the patient agitated, otherwise the blood pressure will rise and the bleeding will increase, and the hematoma should be removed by craniotomy when the indication for surgery is reached to a certain extent. Even if the surgical indication is not reached, the blood volume increases and the absorption time will be prolonged. Certain measures can also be taken, such as the use of hemostatic drugs or even Chinese medicine, to prevent the bleeding from continuing to increase, as well as to promote blood circulation and speed up the absorption of the hematoma.
