Cause of neonatal asphyxia

[Causes] Where can reduce the oxygen concentration of any factors can cause suffocation. Neonatal asphyxia and the fetus in the womb environment and the delivery process closely related. If hypoxia in the production process, fetal blood stimulation of carbon dioxide in the respiratory center, resulting in a strong early action respiratory and throat sphincter and loss of barrier function inhaled a lot of amniotic fluid, causing suffocation at the middle or delivered to the neonatal asphyxia. Such as fetal respiratory center has been paralysis, then delivered a newborn that is not breathing. Neonatal asphyxia caused the mother factors are pregnancy-induced hypertension, threatened son, son, acute blood loss, severe anemia, heart disease, acute infectious diseases, tuberculosis, blood oxygen content to reduce the mother and fetus impact of multiple births, polyhydramnios So that the excessive expansion of the uterus or the placenta early peeling, placenta previa, the placenta functions, are less than the impact of placental blood circulation; umbilical cord around the neck, knotting or prolapsed umbilical cord blood will flow interruption; labor extension, production of abnormal amniotic early break , Not the first basin, producing all kinds of surgery such as forceps, improper handling of the Rotary and the application of anesthesia, analgesia, such as inappropriate drug oxytocin can cause neonatal asphyxia; neonatal airway obstruction, intracranial bleeding, lung development immature, Serious central nervous system, cardiovascular system, such as diaphragmatic hernia deformity and can also lead to the newborn after birth asphyxia.
