      【摘要】 目的 通过不同方式给予早产儿输注氨基酸，评价其营养状况的改善情况。方法 将出生24 h内
体重<2 000 g接受静脉营养治疗的早产儿55例随机分为两组，实验组(n=27)生后24 h内给予1 g/(kg·d)氨基酸输
注，每天增加0.5 g/kg，至3~3.5 g/(kg·d)；对照组(n=28)生后第3天给予0.5 g/(kg·d)氨基酸输注，每天增加0.5 g/kg，
至3 g/(kg·d)。结果 实验组的最大体重下降克数，体重恢复至2 000 g天数均少于对照组。结论 早产儿生后
24 h内输注足量氨基酸有利于改善其营养状况。

【Abstract】 Objective To evaluate the improvements of preterm infants’nutritional status by different ad-
ministrations of intravenous amino acid. Methods Fifty-five preterm infants (birth weight<2 000 g) who were re-
ceiving parenteral nutrition were randomly divided into two groups. The study group (n=27) received 1 g/(kg·d) of ami-
no acid within 24 hours after birth, increased by increments of 0.5 g/(kg·d) to a maximum of 3~3.5 g/(kg·d); The con-
trol group (n=28) received 0.5 g/(kg·d) of amino acid on D3, increased by increments of 0.5 g/(kg·d) until a maximum
of 3 g/(kg·d). Results The study group showed lower postnatal weight loss than the control group, and showed short-
er days to reach 2000 g than the control group. Conclusion Plentiful and early administration of intravenous amino
acid within 24 h after birth is beneficial for the improvement of preterm infants’nutritional status.
