新生儿脐血及生后十天前白蛋白水平对比观察

TNE PREALBUMIN CONCENTRATION IN CORD AND IN SERUM WITHIN TEN DAYS IN HEALTH NEWBORNS

前白蛋白已被做为评估儿童及成人营养状况敏感的生物学指标。本实验观察对比正常足月新生儿143例脐血及生后2～10天静脉血前白蛋白水平。脐血前白蛋白为17.5±5.58mg/dL,明显低于生后2～10天各天静脉血水平(第五天除外)。生后新生儿为混合喂养,蛋白供给1.5～2.5g/kg/天,热卡50～100卡/kg/天。2～10天静脉血前白蛋白为23.4±9.3mg/dL,各天之间无差异,男女之间无差异。

Prealbumin was used as a sensitive biochemical-mark to evaluat the nutrition of children and adults. In our study, we observated 143 cases mature newborns. We tested the prealbumin concentrition in cord for 20 cases, and the others in serum of 2th to loth day of newborns. The average level of prealbumin in cord was 17.5±5.58mg/dl, it was lower than that in serum. But the average level of prealbumin in 5th day was not different from that in cord. The newborn protein intake was 1.5-2.5 g/kg/ day and the calorie intake was 50-100 cal/kg/day. There were no diffe- rence in the prealbumin level for each day and for sex. The mean prealbumin level during 2-10 days was 23.42±9.3mg/dl.
