Recommendations for nutrition of very preterm and very low birth weight infants have developed over time with our understanding of the requirements of preterm babies and the awareness of widespread poor postnatal growth. In general, the trend has been towards enhancing nutrition, but more recent recommendations have begun to raise questions with respect to the potential for high and early nutritional intakes, particularly of protein, to carry risks such as refeeding syndrome. However, large gaps in our knowledge remain for both macro- and micronutrient requirements to support optimal growth and how nutrition and growth relate to important long-term outcomes. Closing these knowledge gaps has been hampered by inconsistent reporting of nutrition intakes and growth parameters, small trials with short-term outcomes and the use of a variety of different methods of monitoring growth. The challenge now is for future research to address these issues through consensus building around the important questions that need to be answered, how to report data from neonatal nutritional trials and whether large trials answering important questions can take place through development of consortia that undertake similar trials in multiple jurisdictions with agreements to share data.
针对极早产儿和极低出生体重儿的营养建议随着我们对早产儿需求的理解以及对广泛存在的不良产后生长的认识而不断发展。总的来说,营养支持的趋势一直是增强的,但最近的建议开始对高营养摄入和早期营养摄入提出了质疑,尤其是蛋白质的摄入,可能会带来重新喂养综合征等风险。然而,我们在宏量和微量营养素需求方面仍然存在很大的知识差距,以支持最佳生长,以及营养和生长与重要的长期结果之间的关系。由于营养摄入和生长参数的报告不一致、短期结果的小型试验以及使用各种不同的生长监测方法,这些知识差距的填补受到了阻碍。现在的挑战是,未来的研究需要围绕需要回答的重要问题达成共识,如何报告新生儿营养试验的数据,以及是否可以通过建立联盟来开展大型试验来回答重要问题,这些联盟在多个司法管辖区开展类似的试验,并同意共享数据。
