If a baby falls on the back of the head while sitting, if it is only a skin injury, disinfecting the wound is enough and it is generally not important; however, if it is complicated by subdural or intracranial hemorrhage, the situation is more urgent. If a baby falls on the back of the head while sitting, if the baby’s mental state is good and there are no symptoms such as projectile vomiting, convulsions, lethargy, coma, etc., it is only a superficial injury, and local disinfection is enough, which will not pose a threat to the baby’s life safety. However, if the above symptoms occur and worsen progressively, urgent medical treatment is needed to rule out complications such as subdural hemorrhage and intracranial hemorrhage, so as not to lead to craniocerebral injury, which may jeopardize the child’s life or form sequelae. Parents are advised to take their children to the doctor for timely medical treatment, and adopt scientific treatment methods under the evaluation of specialists.
