The common causes of pediatric cerebral palsy are: 1. Low weight infants: including premature immature infants and full-term small-like infants. 2, congenital anomalies: including abnormal brain development caused by various reasons. 53% of cerebral palsy patients with tetraplegia are related to congenital anomalies; 35% of cerebral palsy patients with non-tetraplegia are due to congenital dysplasia. 3. Cerebral ischemia and hypoxia: 20% of cerebral palsy patients are caused by asphyxia and birth injury, and the factors leading to ischemia and hypoxia are: (1) Maternal factors: such as gestational hypertension syndrome, heart failure, hemorrhage, anemia, shock or drug overdose; (2) Placental factors: such as placental abruption, placenta praevia, placental necrosis or placental malfunction; (3) Umbilical cord blood flow blockage: such as cord prolapse, compression, knotting or winding (4) abnormal delivery process: such as breech delivery, stalled delivery, surgical delivery (forceps) or application of anesthetics, etc. (5) neonatal factors: in addition to asphyxia, there are many abnormal cardiopulmonary diseases. Such as: congenital heart disease, respiratory distress syndrome, peripheral circulation failure, erythrocytosis. (4) Nuclear jaundice: It is an important cause of cerebral palsy, but with the progress of domestic medicine, the proportion of cerebral palsy caused by nuclear jaundice has decreased.
