Patient: My baby was born by cesarean section beyond the due date, the baby’s amniotic fluid was second degree contaminated and hypoxic at birth, the baby started screaming and did not sleep at birth, and was later examined for ischemic-hypoxic encephalopathy and subarachnoid hemorrhage, then injected with cranial pressure lowering medication and vitamin K. After the bleeding stopped, she was sent to the neonatal unit of the provincial children’s hospital and was discharged after 10 days of hospitalization. Her neck is normal, she can hold up for a while, she cries when she has to pee, she can pee, her eyes follow the movement of objects, but she can’t look for sound sources, she sometimes looks away when she talks, she doesn’t react, and she can’t be made to laugh. The skull overlap has not yet opened. The baby has not yet had a CT review. If the blood in the skull has been absorbed, will the baby still have sequelae? Is the condition now a brain developmental delay? If there are sequelae of epilepsy, when can they develop and can they be detected early? When can the skull overlap be opened in general? If it takes a long time to open, what will be the effect on brain development? The hearing and vision tests are normal, and the baby was prescribed 10 days of ganglioside at the one and a half month review, which has now been injected. In this case of your child, you are advised to feed normally and follow up. You can observe the fullness of the child’s fontanelle and the change in head circumference with the naked eye. CT can also be done regularly, but children should have it done as little as possible and only when the doctor recommends it. The situation you described and the results of the examination cannot be said that the child has any abnormality. It is not yet a delayed brain development. Of course some symptoms are gradually manifested during the child’s growth. The subarachnoid hemorrhage is easily complicated by hydrocephalus, which also needs to be observed at a later stage to know, and generally a small amount of blood will not leave any sequelae after absorption. If epilepsy is not found now, preventive treatment is not considered for the time being. Cranial overlap will gradually open after brain development, it is not time yet, if the head circumference is found to be smaller than normal children for a long time, the brain can be found through CT examination .
