Patients who have suffered a fall on the back of the head generally have few problems, but should also be closely monitored for nausea, projectile vomiting, and impaired consciousness. Most of the patients are mainly manifested as subcutaneous hematoma, in this case, the main local pain, there will be no neurological signs. Cold compresses can be given in the early stage, and after 48 hours, if there is no more bleeding, hot compresses can be considered to promote the absorption of the hematoma, and local physical therapy can also be considered if necessary. If there are no special circumstances, the hematoma will gradually absorb and dissipate without causing obvious clinical symptoms. As for the high fall injury, if the back of the head is injured, it may cause more serious intracranial hemorrhage, and the patient may have different degrees of consciousness disorder, or even coma, and may also have projectile vomiting, optic papilla edema, etc. In this case, it is also necessary to do head surgery in time. In this case, it is also necessary to do a CT or MRI examination of the head in order to clarify whether there is an intracranial hemorrhage. Conservative treatment can be considered for small intracranial hemorrhages, such as stopping bleeding and replenishing fluids, and observing vital signs and pupil changes. If the amount of bleeding is large, emergency surgery is also needed to save lives.
