等差递增肠内营养用于早产儿及极低出生体重儿研究

目的探讨不同的肠内营养量对早产儿及极低出生体重儿体格发育的影响。方法将60例早产儿及极低出生体重儿随机分对照组和观察组各30例,在静脉营养支持的基础上,根据患儿每天的体质量计算所需营养总量(15mL/kg),对照组采用传统的平均分配营养量的方法即8次/d均分;观察组采用等差递增公式计算每次的营养量。连续14d后评价效果。结果患儿体质量显著重于对照组,胎便排尽及黄疸持续时间显著短于对照组,喂养不耐受发生率、胃残留量及每日排便次数显著少于对照组(P<0.05,P<0.01)。结论对早产儿及极低出生体重儿采用等差递增肠内营养量的方法可循序渐进地刺激患儿肠道,有利于患儿体格发育,效果优于平均分配营养量法。

Enteral nutrition fed to premature and very low birth weight infants with arithmetic progression

Objective To investigate the effect of different amounts of enteral nutrition on physique development of premature and very low birth weight infants. Methods Sixty premature and very low birth weight infants were equally randomized into a control group and an observation group.On the basis of intravenous nutritional support,daily required nutrition was calculated according to infant daily weight(15 mL/kg).Infants in the control group were fed eight times per day by using traditional method of the total amount of nutrition being evenly divided,while for the observation group the feeding amount was increased with an arithmetic increment.The effect was evaluated after 14 days. Results Compared with the control group,infants′ body weight in the observation group was significantly increased;length of complete meconium excretion and duration of jaundice were significantly shorter;incidence rate of feeding intolerance,gastric residual volume,and defecation frequency were significantly lower in the observation group(P<0.05,P<0.01). Conclusion Enteral nutrition fed to premature and very low birth weight infants with the feeding amounting in an arithmetic increment,can stimulate infant′s intestinal tract step by step and help boost physique development.
