Abstract

Purpose. Results of a meta-analysis of data from clinical studies comparing patient outcomes and hospital length of stay (LOS) in surgical patients receiving fish oil (FO)-containing i.v. fat emulsions (IVFEs) versus non-FO-containing IVFEs are presented. Methods. Computerized searches of the MEDLINE, Embase, and Coch rane CENTRAL databases were performed in August 2014 to identify Englishlanguage articles on randomized controlled trials (RCTs) comparing FO-containing and non-FO-containing IVFEs in adult surgical patients receiving parenteral nutrition. Selected articles were analyzed for methodological and publication bias and study heterogeneity (I2 statistic). Results. Data from 19 RCTs (total n = 1,167) were included in the meta-analysis. Compared with use of non-FO-containing IVFEs (products based in soybean oil [SO], medium-chain triglycerides, or olive oil), use of FO-containing IVFEs was associated with reduced infectious morbidity (odds ratio [OR], 0.44; 95% confidence interval [CI], 0.30-0.65; p < 0.0001; I2 = 0%); the effect size was greatest for FO-containing versus SO-based IVFEs. Relative to use of SO-based IVFEs, use of FO-containing IVFEs was associated with a significant reduction in hospital LOS (weighted mean difference, -2.70 days; 95% CI, -3.60 to -1.79 days; p < 0.00001; I2 = 0%). Conclusion. The results of the meta-analysis indicated that FO-containing IVFEs could improve infectious morbidity and LOS. The overall effect of reducing infectious morbidity and LOS was found to be the greatest in comparison with the SO-based IVFEs.
