INTRODUCTION: Previous studies have shown that interleukin-6 (IL-6) levels correlated with mortality in critically ill patients. GOAL: To determine the effect of ketamine on IL-6 levels in liver resections patients with a temporary porto-arterial occlusion (Pringle manoeuvre). MATERIALS AND METHODS: Controlled, prospective, randomized, double-blinded study. One group (n = 21) received ketamine whereas the other group (n = 17) received placebo. IL-6 levels were obtained at baseline, 4, 12, 24 h, 3 and 5 days. RESULTS: There were no significant differences in IL-6 levels between the groups (basal P = 089, 4 hP = 0.83, 12 h P = 0.39, 24 h, P = 0.55, 3 days P = 0.80 and 5 days P = 0.45). Both groups had elevated IL-6 levels that became almost undetectable by day 5. There was no major morbidity and no mortality in either group. CONCLUSIONS:Ketamine does not seem to have an effect on plasma levels of IL-6. This could be interpreted as a potential finding associated with outcome as we did not encounter any deaths or major complications. Further studies will likely be needed to determine the range of IL-6 levels associated with survival and mortality, and whether it could be a predictor of survival.
