Patient's question:
An eight-year-old child was knocked down at school with the back of his head hitting the ground, resulting in bleeding. He was admitted to the hospital for examination, but no abnormalities were found in the CT scan. He was simply bandaged and sent home. Two days have passed, and the child is still experiencing dizziness and nausea. Is there a problem?Doctor's answer:
Medical Analysis: Hello: According to your description, the child had a head injury 2 days ago. At that time, a brain CT scan did not show any abnormalities. After being bandaged, they still experience dizziness and nausea. This is a common symptom of a head injury, related to brain tissue edema caused by trauma. Generally, brain edema reaches its peak about 3 days after the injury. It did not appear immediately, and if there are no complications such as brain bleeding after 5 to 7 days, the dizziness and nausea will gradually subside.Advice: For the current condition, it is recommended to have a follow-up brain CT scan to rule out the possibility of delayed intracranial hemorrhage. If the examination confirms brain bleeding, it is necessary to actively administer mannitol for dehydration and reduce intracranial pressure to alleviate brain edema. If the examination shows no brain bleeding, it can be considered as simple brain tissue edema. In this case, a small amount of intravenous mannitol can be administered to reduce brain edema, and the symptoms of dizziness and nausea will quickly improve. There is no need to worry.
