Abstract
Background: Preclinical and clinical studies suggest that supplementation with omega-3 fatty acids after trauma
might reduce subsequent posttraumatic stress disorder (PTSD). To date, we have shown in an open trial that PTSD
symptoms in critically injured patients can be reduced by taking omega-3 fatty acids, hypothesized to stimulate
hippocampal neurogenesis. The primary aim of the present randomized controlled trial is to examine the efficacy of
omega-3 fatty acid supplementation in the secondary prevention of PTSD following accidental injury, as compared
with placebo. This paper describes the rationale and protocol of this trial.
Methods/design: The Tachikawa Project for Prevention of Posttraumatic Stress Disorder with Polyunsaturated Fatty
Acid (TPOP) is a double-blinded, parallel group, randomized controlled trial to assess whether omega-3 fatty acid
supplementation can prevent PTSD symptoms among accident-injured patients consecutively admitted to an
intensive care unit. We plan to recruit accident-injured patients and follow them prospective
