胎儿体内铁增积率在妊娠末期显著增加,早产儿出生时铁贮存少,生后生长发育快,铁需要量大,易患缺铁性贫血。本文对早产儿铁代谢特点与缺铁的预防研究进作展一综述。铁贮存在宫内,胎儿铁增积率与体重增长成正比(表1),平均维持在75mg/kg。无论是 Fetal body iron deposition rate increased significantly in the end of pregnancy, premature children born less iron storage, rapid growth after birth, iron demand, susceptibility to iron deficiency anemia. This article reviews the characteristics of iron metabolism in preterm infants and the prevention of iron deficiency. Iron is stored in the uterus, and the rate of fetal iron accumulation is proportional to body weight gain (Table 1), with an average maintenance of 75 mg / kg. Whether it is
