How much do you know about the causes of fetal cerebral palsy?

1. Low birth weight babies (less than 2500g): including premature babies and full-term small babies.

2. Congenital abnormalities: including brain development abnormalities caused by various reasons. Among patients with cerebral palsy with quadriplegia, 53% are caused by congenital abnormalities; among patients with cerebral palsy without quadriplegia, 35% are caused by congenital maldevelopment.

3. Cerebral ischemia and hypoxia: 20% of cerebral palsy patients are caused by asphyxia and birth trauma. The factors leading to ischemia and hypoxia are as follows:

(1) Maternal factors: such as pregnancy-induced hypertension, heart failure, heavy bleeding, anemia, shock, drug abuse, drug overdose, etc.;

(2) Placental factors: such as placental abruption, placenta previa, placental necrosis or placental dysfunction;

(3) Umbilical cord blood flow obstruction: such as umbilical cord prolapse, compression, knotting or entanglement;

(4) Abnormal delivery process: such as breech delivery, delayed labor, surgical delivery (forceps) or use of anesthetics;

(5) Neonatal factors: In addition to asphyxia, there are many cardiopulmonary dysfunction diseases. Such as: congenital heart disease, respiratory distress syndrome, circulatory failure, polycythemia.

4. Kernicterus: It is an important cause of cerebral palsy. However, with the continuous advancement of medical technology, the proportion of cerebral palsy caused by kernicterus has decreased.
