BackgroundThere is growing interest in the use of ω-3 fatty acid (n-3FA) lipid emulsions to prevent complications associated with parenteral nutrition. The authors systematically reviewed the evidence on the benefits and safety of n-3FA compared with standard lipid emulsions in children with intestinal disease, critical illness, trauma, or postoperative complications.Materials And MethodsThe authors searched 4 bibliographic databases from their inception to March 2011, conference proceedings, trial registries, and reference lists. Two reviewers independently selected studies, assessed methodological quality, and rated the strength of the evidence. One reviewer extracted and a second reviewer verified data. The authors summarized findings qualitatively and conducted meta-analysis when appropriate.ResultsFive randomized controlled trials with unclear risk of bias and 3 high-quality prospective cohort studies were included. The studies examined premature, low birth weight infants (n = 6) and children with heart disease (n = 1) or intestinal failure (n = 1). The strength of evidence was consistently low or very low across all lipid emulsion comparisons and outcomes. In young children, n-3FA emulsions resulted in improvement in some biochemical outcomes of intestinal failure-associated liver disease but no difference in mortality. Few studies examined patient-important outcomes, such as length of hospital and intensive care stay; need for transplantation, growth, and cognitive development; or the long-term effects and potential harms associated with these therapies.ConclusionsCurrently, there is a lack of sufficient high-quality data to support the use of parenteral n-3FA lipid emulsions in children. Future trials examining long-term clinical outcomes and harms are needed.
