Background  Septic shock remains a leading cause of death worldwide. Hyperbaric oxygen treatment (HBO 2 ) has been shown to alter the inflammatory response during sepsis and to reduce mortality. A therapeutic window of HBO 2  treatment has been demonstrated experimentally, but optimal timing remains uncertain. We investigated the effects of 24 h delayed normobaric oxygen (NBO 2 ) and HBO 2  treatment on the endogenous production of the inflammatory markers interleukin (IL)-6, tumor necrosis factor (TNF)-α and IL-10, and on mortality in rats with cecal ligation and puncture (CLP) induced sepsis.    Method  Fifty-five male Sprague-Dawley rats underwent CLP and were randomized to the following groups: 1) HBO 2  2.5 bar absolute pressure (p abs ); 2) NBO 2  1.0 bar p abs ; 3) Control (no-treatment), and they were individually monitored for 72 h with intermittent blood sampling.    Results  IL-6, TNF-α, and IL-10 were increased 24 h after the procedure, and IL-6 was significantly higher in non-survivors than in survivors. The level of IL-10 was significantly higher at hour 48 in the HBO 2  group compared to control ( p  = 0.01), but this was not the case at other time points. No other significant differences in cytokine levels were found for any group comparisons. Delayed NBO 2  and HBO 2  treatment failed to change the mortality in the animals.    Conclusion  High levels of IL-6 in non-surviving animals with sepsis suggest that IL-6 is a potential biomarker. We found a significantly higher concentration of IL-10 in the HBO 2  group at hour 48 vs. control animals. However, 24 h–delayed treatment with HBO 2  did not change the levels of pro-inflammatory cytokines and survival, suggesting that earlier intervention may be required to obtain an anti-inflammatory effect.
