Early prevention of cerebral palsy is of great importance in reducing the burden on families and society and improving the quality of the population. How can prevention be carried out? The first is before birth, i.e. from the mother’s pregnancy to delivery. The development of the fetal nervous system is superior to the development of 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 early prenatal examination, fetal prediction, eugenics publicity and education, and good perinatal health care to prevent congenital diseases in the fetus. Pregnant women should quit bad habits, such as smoking and drinking alcohol; do not abuse drugs such as anesthetics and sedatives; avoid virus infections such as influenza and rubella 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 have prenatal checkups as early as possible: 1, older pregnant women (over 35 years old) 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 with a history of epilepsy, cerebral palsy and other genetic diseases. If fetal abnormalities are found early in pregnancy, terminate the pregnancy as early as possible. The next 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 premature birth and obstructed labor, improve the medical skills and medical ethics of medical personnel, carefully and meticulously handle all aspects of delivery, and do a good job in handling obstructed fetuses, which is an extremely important part of preventing the occurrence of pediatric cerebral palsy. Once again, we should strengthen the care of the fetus within one month after birth, feed it reasonably, prevent intracranial infections and traumatic brain injury, and if they occur, go to the hospital as soon as possible.
