The risk period for traumatic brain hemorrhage is usually around 7-10 days, but it should be judged according to the actual condition of the patient. Most patients with traumatic brain hemorrhage can be treated with internal medicine, and the risk period for such cases is basically about 7-10 days. However, there are some cases of traumatic brain injury and brain hemorrhage that need to be treated by craniotomy, and the condition is relatively serious, so the risk period is about 2-3 weeks, or even about a month. It must be combined with head CT, head MRI, and cerebral angiography and other related tests to clarify together, and it must be noted that traumatic brain hemorrhage is not simply a simple treatment of brain hemorrhage, but also a series of conditions such as lung infection and venous thrombosis may also need to be treated. Therefore, its risk period should be determined according to the actual situation.
