This suggests that efforts to improve outcome in septic patients by manipulating systemic oxygen delivery and regional blood flow are doomed to failure. That suggestion remains largely speculative and experimental and clinical results presented here consistently demonstrate that there is still a place for treatment of abnormal perfusion in the context of early severe sepsis and septic shock. Keywords cytopathic hypoxia haemodynamics oxygen delivery sepsis shock In his review paper published in the present issue of Critical Care Stephan Jakob 1 deals with the difficult and broad topic of splanchnic ischaemia in critical care. The presentation is exhaustive including the still controversial issue of inadequate gastrointestinal flow in septic states. As mentioned in that review several lines of evidence support the notion that cellular energetics are deranged in sepsis in terms not only of inadequate tissue perfusion but also of impaired mitochondrial respiration and or coupling . organ dysfunction in sepsis may occur as a result of cytopathic hypoxia 2 . If this is correct then the therapeutic implications might be enormous. It would imply that
