After a head collision in children, there is usually no need for concern if there is no localized mass, vomiting, headache or other discomforts; if there are symptoms such as vomiting, even if there is no mass, CT or other examinations are recommended.
For mild head collision without mass and localized breakage and bleeding, without vomiting, headache, memory abnormality and other manifestations, there is usually no need to worry and only clinical observation is needed. If the above symptoms occur some time after the injury, one needs to be alert to late hemorrhage and other conditions.
For those who have a short period of impaired consciousness after injury, accompanied by headache, vomiting and other symptoms, even if there is no local hematoma, it is necessary to go to the hospital in a timely manner to perform brain CT, electroencephalography and other tests to determine whether there is a craniocerebral injury, such as concussion.
After head trauma, it is recommended to go to the hospital in time to avoid adverse consequences.
