Omega-3 fatty acids improve the diagnosis-related clinical outcome*

Administration of omega-3 fatty acid may reduce mortality, antibiotic use, and length of hospital stay in different diseases. Effects and effect sizes related to fish oil doses are diagnosis dependent. In view of the lack of substantial study literature concerning diagnosis-related nutritional single-substrate intervention in the critically ill, the present data can be used in formulating hypotheses and may serve as reference doses for randomized, controlled studies, which may, for instance, confirm the value of omega-3 fatty acid in the adjunctive therapy of peritonitis and abdominal sepsis.
