Note feeding premature infants

Refers to premature babies 37 weeks of pregnancy childbirth dissatisfaction newborn, feeding the needs of mothers of premature infants and care more carefully. Breast milk contains easy to digest and absorb protein, fat, lactose, there is an appropriate amount of trace elements, vitamins, enzymes and other immune factors, is the best food for premature babies. However, due to the physiological characteristics of premature infants, breast milk of certain trace elements (iron, zinc, etc.) and vitamins (D, C, B, etc.) can not guarantee the supply of their needs, and these nutrients is to ensure that physical development of premature infants intelligence necessary , if not to add these nutrients will result in a lack of nutrients, which is not conducive to intellectual development in preterm infants. Occur in preterm infants calcium, iron and zinc in serum is due to the lower value of the latter part of pregnancy is completed fetal trace element necessary for normal body reserves through an important stage, premature birth premature infants can not come out so that the fetus late in pregnancy from mother to gain adequate reserves of the body, thus the lack of easy. Such as: 1, calcium accumulation late pregnancy the total volume accounted for 80%, and premature infants less calcium and phosphorus in human milk, even though breastfeeding is adequate calcium intake is only of late fetal 1 / 3 ~ 1 / 2, In addition, lack of acid secretion, the absorption of fat-soluble vitamin D is low, so the smaller the gestational age of premature infants more prone to calcium deficiency, and growth in preterm infants than full-term infants, it is prone to calcium deficiency rickets. 2, the re-absorption of iron usually occurs in the near term time, the premature infant less than the reserves of iron. 3, the last 3 months of intrauterine fetal zinc storage capacity of 250g/kg? D, birth, high blood zinc, the zinc deficiency rare full-term infants, gestational age in premature infants due to inadequate storage of zinc less than In addition, human milk content of zinc in the growth of premature infants can not meet the requirements, so easy to zinc deficiency. Breast milk of vitamin E, C, B group and the lack of folic acid content, and faster growth in premature infants, the demand for these relatively large vitamin. Therefore, breast-feeding in premature infants can not be fully satisfied of certain trace elements, vitamins, etc., to be appropriate to add.
