A term fetus may have cerebral palsy if there is a lack of oxygen to the fetus. An expired fetus, also known as a term birth, is a fetus delivered after forty-two weeks of pregnancy. Cerebral palsy is a disorder in which a child suffers non-progressive, central motor dysfunction due to damage to the brain parenchyma caused by a variety of factors, such as infection, hemorrhage, and trauma. One of the causes of pediatric cerebral palsy is overdue birth. Overdue births are more likely to have intrauterine distress and hypoxia, which can lead to cerebral edema and intracranial hemorrhage due to hypoxia, causing damage to the brain tissues, which can lead to cerebral palsy in the fetus. Fetus with large size will affect uterine contraction during labor and delivery, and it is easy to have weak contraction and stagnant labor during delivery, and the fetus will suffer from hypoxia, which will increase the chance of cerebral palsy. After pregnancy, do a good job of pregnancy checkups, and try to avoid delivering the baby after the expiration date.
