本文通过测定血清铁蛋白、血红蛋白、平均红细胞体积(MCV)、总铁结合力(TIBC)、未饱和铁结合力(UIBC)等,对低出生体重儿进行了出生后的铁代谢动态的追踪观察,特别就血清铁蛋白值生后变化和未成熟儿晚期贫血进行了研究和探讨。对象低出生体重儿35例,胎龄平均32.6±2.9周(28～40周),出生体重平均1,601±355 g(820～2,340 g),其中适于胎龄儿27例,小于胎龄儿8例。发现早产儿窒息8例、呼吸窘迫综合征7例、低血糖症3例、气胸1例。另外,特发性高胆红素血症2例,Rh因子不合的新生儿溶血性黄疸1例接受了换血。方法足跟穿刺采取末梢血,在0～4日龄以及
In this paper, we observed the postnatal iron metabolism dynamics of low birth weight infants by measuring serum ferritin, hemoglobin, mean corpuscular volume (MCV), total iron binding capacity (TIBC), and UIBC , In particular, changes in serum ferritin after birth and immature children with anemia were studied and discussed. Subjects 35 cases of low birth weight children, average gestational age 32.6 ± 2.9 weeks (28 to 40 weeks), birth weight average 1,601 ± 355 g (820 ~ 2,340 g), of which 27 were suitable for gestational age children, gestational age less than 8 example. 8 cases of asphyxia in preterm children, 7 cases of respiratory distress syndrome, 3 cases of hypoglycemia and 1 case of pneumothorax were found. In addition, idiopathic hyperbilirubinemia in 2 cases, Rh factor incompatibility in 1 case of hemolytic jaundice received transfusions. Methods Heel puncture to take peripheral blood, at 0 to 4 days of age as well
