Background & AimsThis study assessed the effects of administering a lipid emulsion containing eicosapentaenoic and docosahexaenoic acid before and after open-heart surgery on cytokine production and length of hospital stay in infants.MethodsThirty-two infants (40 ± 2.3 weeks gestational age; 10.6 days at time of surgery) undergoing open-heart surgery with cardiopulmonary bypass were randomized to receive an intravenous lipid emulsion with (treatment) or without (control) eicosapentaenoic and docosahexaenoic acid in this prospective, randomized, double-blind, controlled trial.ResultsMean plasma TNF-α concentration was significantly (p = 0.003) lower in the treatment (5.9 pg/mL) compared to the control group (14.8 pg/mL). In infants without sepsis, plasma TNF-α did not differ according to treatment, however when sepsis developed, mean plasma TNF-α was 21.1 pg/mL and 1.5 pg/mL (p = 0.0007) in control and treatment groups, respectively. Plasma TNF-α was positively correlated with length of hospital stay in the control group (p = 0.01), and negatively correlated with length of stay in the treatment group (p = 0.004), with a significant time by treatment interaction (p = 0.02).ConclusionsProviding a lipid emulsion containing eicosapentaenoic and docosahexaenoic acid reduces TNF-α concentrations in infants undergoing open-heart surgery. Lipid emulsions containing eicosapentaenoic and docosahexaenoic acid may ameliorate the inflammatory response among critically ill infants.Copyright © 2011 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.
