The first is before birth, that is, from the mother’s pregnancy to delivery. The development of the fetal nervous system is superior to other systems, and the fetus depends on the mother for survival, so the health and nutritional status of the pregnant woman is closely related to the growth and development of the fetus, which requires active prenatal checkups, fetal prediction, eugenics publicity and education, and perinatal health care to prevent congenital diseases in the fetus. Pregnant women should give up bad habits, such as smoking, drinking alcohol; do not abuse narcotics, sedatives and other drugs; avoid influenza, rubella and other viral infections and contact with cats and dogs; avoid exposure to harmful and toxic substances such as radiation and frequent ultrasound examinations, and preferably do not watch TV and operate computers. In addition, pregnant women with the following conditions should do prenatal checkups as soon as possible: (1) older pregnant women (35 years old or older) or men over 50 years old. (2) Marriage between close relatives. (3) History of unexplained miscarriage, premature birth, stillbirth and neonatal death. (4) Pregnant women with mental retardation, or both close relatives have a history of epilepsy, cerebral palsy or other genetic diseases. If fetal abnormalities are detected early in pregnancy, the pregnancy should be terminated as soon as possible. The second is at birth, i.e. during delivery. Fetal asphyxia and intracranial hemorrhage caused by intrapartum factors are an important cause of pediatric cerebral palsy. Therefore, we should prevent preterm birth and obstructed labor, improve the medical skills and ethics of medical personnel, handle all aspects of delivery carefully, and do a good job in handling obstructed fetuses, which is an extremely important part of preventing the occurrence of pediatric cerebral palsy.
