摘要
测定新生儿前白蛋白、转铁蛋白、白蛋白水平 ,探讨其作为评价新生儿营养状况的价值。对 1 7例早产儿、1 2例足月儿采股静脉血分别测定其前白蛋白、转铁蛋白、白蛋白水平。结果显示 ( 1 )早产儿前白蛋白水平 ( 8 1 6± 2 0 9)mg dl明显低于足月儿 ( 1 0 73± 2 2 9)mg dl(P <0 .0 1 ) ,而早产儿、足月儿两组转铁蛋白、白蛋白水平比较无显著差异 (P >0 .0 5 )。 ( 2 )早产儿生后 3天测前白蛋白水平较开奶前有明显上升 (P <0 0 1 ) ,而转铁蛋白、白蛋白水平无明显变化。 ( 3)新生儿体重与前白蛋白水平量正相关 ,早产儿、足月儿体重与前白蛋白水平分别呈中度 (r=0 .44)和高度 (r =0 .87)相关。研究表明前白蛋白水平有助于区分LGA、AGA及SGA ,在反映新生儿营养状况方面比白蛋白。
To explore the significance in evaluation nutrition status of prealbumin and transferrin in newborn infants. The prealbumin, transferrin and serum albumin were determined in 17 neonates born before 37 weeks gestation and 12 neonates born at term. Results showed (1) neonates born before 37 weeks gestation had signifcantly lower prealbumin levels (8.16±2.09mg/dl) than those born at term (10.73±2.29mg/dl) (P<0.01). There were no significant differences of the results of transferrin and serum albumin levels between preterm infants and neonates born at term ()>0.05). (2)feefing caused a significant increase of prealbumin levels in preterm infants three days after birth (P<0.01) (3)this study also showed a significant correlation between birth weight and prealbumin levels in 17 infants <37 weeks and 12 infants ≥37 weeks (r=0.44,0.87). Therefore prealbumin levels can be used to distinguish between groups of LGA, AGA and SGA infants. Prealbumin is established more useful than transferrin and serum albumin in evaluating nutrition status.
