What causes premature infants?

summary

The shorter the gestational age, the smaller the weight and the shorter the length of the baby. Live birth infants born before 37 full weeks of gestational age are called premature or immature infants. Most of them have birth weight less than 2500g and head circumference less than 33cm. A small number of preterm infants who weigh more than 2500g and whose organ function and adaptability are worse than those of full-term infants, what causes preterm infants? Let's talk about it

What causes premature infants?

The calculation of the expected date of labor due to human factors is wrong. Placental factors include placental abruption, placenta previa or placental insufficiency. Fetal factors include congenital malformation, infection, fetal and maternal blood group incompatibility, multiple pregnancy, too short umbilical cord, too much or too little amniotic fluid.

Maternal factors include malnutrition, excessive fatigue, severe physical and emotional injury, preeclampsia, hypertension, diabetes, cardiopulmonary disease and infectious febrile diseases. Recently, it is considered that 50% - 80% of premature delivery is related to chorionic inflammation.

Children in families with low social and economic status are prone to malnutrition, overwork, overproduction or poor prenatal care. Frequent pregnancy of mother, too old or too young of parents, too much smoking, etc.

matters needing attention

Premature infants need more than mature infants, because the last stage of the fetus is the stage of increasing inorganic salts, such as calcium, phosphorus and iron. Less than one month, premature infants will lack inorganic salts.
