After hitting the head, the first thing to do is to clarify whether there is any epidermal contusion or laceration, active bleeding, and the degree of bleeding at the injured area. However, it is more important to clarify the state of consciousness of the injured person, and the state of consciousness after the injury determines the degree of brain injury. If there is primary coma after the injury, it means that the degree of brain damage is very serious. Some patients appear brief coma and then awake, after a period of time and then coma, in the terminology known as intermediate wakefulness, often suggests that the patient has an intracranial hemorrhage, commonly an epidural hematoma. The surgical prognosis for this hemorrhage is excellent if treated promptly. Once treatment is delayed, even by a few minutes, it can lead to catastrophic consequences, such as death or disability. In addition, it is important to observe the patient’s functional status, such as movement and motion of the arms and legs, the presence of hemiparesis and epilepsy, which are also parts that need to be closely monitored.
