Although crucial in improving health outcomes in the preterm infants, parenteral nutrition (PN) is not without risk, especially if handled improperly. A growing body of evidence suggests that components of PN admixtures, including lipid injectable emulsions (ILEs), are susceptible to degradation, including oxidation when exposed to light (ie, photo-oxidation), resulting in the production of reactive oxygen species. Infants, especially those born preterm, are considered more susceptible to consequences of oxidative stress than children and adults. Oxidative stress is associated with bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and intestinal failure-associated liver disease. The American Society for Parenteral and Enteral Nutrition (ASPEN) assembled a working group to provide recommendations on clinical practice surrounding photoprotection of PN.This Position Paper reviews the scientific literature on the formation of quantifiable peroxides and other degradation products when PN admixtures and ILEs are exposed to light and reports adverse clinical outcomes in premature infants exposed to PN. Recommendations for photoprotection of PN admixtures and ILEs are provided, as well as the challenges in achieving complete photoprotection with the equipment, supplies, and materials currently available in the US. ASPEN and the authors understand that the full implementation of complete photoprotection may not currently be feasible given current product availability; recommendations provided in this paper serve to represent the goal to which to strive as well as to highlight the importance of product availability to achieve these practices. This paper has been approved by the ASPEN Board of Directors.
尽管肠外营养(PN)对改善早产儿的健康结局至关重要,但并非没有风险,尤其是处理不当的情况下。越来越多的证据表明,PN混合液的成分,包括脂质注射乳剂(ILEs),容易发生降解,包括暴露于光线下时发生氧化(即光氧化),从而产生活性氧。婴儿,尤其是早产儿,被认为比儿童和成人更容易受到氧化应激后果的影响。氧化应激与支气管肺发育不良、早产儿视网膜病变、坏死性小肠结肠炎和肠衰竭相关肝病有关。美国肠外和肠内营养学会(ASPEN)组建了一个工作组,就PN光保护的临床实践提供建议。本立场文件回顾了有关PN混合液和ILEs暴露于光线下时可量化过氧化物和其他降解产物形成的科学文献,并报告了暴露于PN的早产儿的不良临床结局。提供了PN混合液和ILEs光保护的建议,以及在美国目前可用的设备、用品和材料实现完全光保护所面临的挑战。ASPEN和作者明白,鉴于目前的产品供应情况,目前全面实施完全光保护可能不可行;本文提供的建议旨在代表努力的目标,并强调产品供应对实现这些做法的重要性。本文已获ASPEN董事会批准。
