It is not recommended to judge on your own if your child has suffered a fall on the head; a professional physician can make a comprehensive judgment on whether there is anything wrong through systematic physical examination, CT and other imaging results. Compared with adults, children’s skulls are more fragile and easy to be damaged after a fall. At the same time, due to the imperfect development of language function in some infants and young children, they cannot express their own symptoms perfectly, which may lead to the injury being overlooked, therefore, it is not recommended to judge the injury on the basis of subjective symptoms by oneself. After a head injury, it is recommended to go to the hospital for a systematic examination by a professional clinician to check whether there is any intracranial or extracranial hemorrhage or hematoma, whether there is any damage to the skull, whether there is any neurological damage such as concussion, etc. For those who are highly suspected of having intracranial injuries, it is recommended to go to the hospital to have a systematic examination. For those who are highly suspected of intracranial injury, it is recommended that further examinations such as cranial CT be performed to clarify the injury. In addition, if symptoms such as coma and vomiting appear directly after the fall, it is necessary to go to the hospital immediately for emergency treatment.
