According to this hypothesis- interventions aimed at preventing or reversing mitochondrial damage may have major clinical relevance- although the timing of such interventions will be critical to both ensuring benefit and avoiding harm. Early correction of tissue hypoxia- strict control of glycaemia- and modulation of oxidative and nitrosative stress may afford protection during the initial- acute systemic inflammatory response. The regulated induction of a hypometabolic state resembling hibernation may protect the cells from dying once energy failure has developed- allowing the possibility of functional recovery. Repair of damaged organelles through stimulation of mitochondrial biogenesis and reactivation of cellular metabolism may accelerate resolution of the multiple organ failure syndrome. Introduction Sepsis is the systemic inflammatory response to infection and represents a major cause of morbidity and mortality in patients admitted to intensive care units ICUs 1 . However- despite decades of research- the pathophysiology of sepsis remains incompletely understood. A critical limitation
