Breast feeding alone does not provide adequate nutrition for growth in preterm infants; therefore, fortifiers are added when over 70-80 cc/kg/day of breast milk is tolerated. As there are few studies comparing early and late breast milk fortification, the following study was conducted.
This double-blind clinical trial was performed on 80 preterm infants (gestational age of 28-34 weeks, birth weight <2 kg). The newborns were randomly divided into two groups to receive either early or late fortification. The primary and secondary outcomes were the difference in growth indices and complications (including feeding intolerance, necrotizing enterocolitis (NEC), and septicemia) between the two groups, respectively.
Both groups showed increases in growth indices; however, there was no statistically significant difference in increments of growth indices and complications between the two groups.
Our findings suggest that early fortification from the first feeding in neonates with exclusive breast feeding did not improve growth in the first 4 weeks in preterm neonates in comparison with late fortification; so early fortification may not be cost effective.
仅母乳喂养不能为早产儿的生长提供足够的营养;因此,当早产儿每天耐受超过70 - 80毫升/千克的母乳时,需添加强化剂。由于比较早期和晚期母乳强化的研究较少,故开展了以下研究。
本双盲临床试验对80名早产儿(胎龄28 - 34周,出生体重<2千克)进行。新生儿被随机分为两组,分别接受早期或晚期强化。主要和次要结局分别是两组之间生长指标和并发症(包括喂养不耐受、坏死性小肠结肠炎(NEC)和败血症)的差异。
两组的生长指标均有所增加;然而,两组之间生长指标的增量和并发症方面无统计学显著差异。
我们的研究结果表明,与晚期强化相比,纯母乳喂养的新生儿从首次喂养就开始早期强化在早产儿出生后的前4周内并未改善生长情况;因此早期强化可能不具有成本效益。
