Muscle dysfunction in intensive care units is associated with significant morbidity and mortality. During septic shock, there is an increased catabolism and systemic inflammation resulting in quantitative and qualitative muscle impairment. In the intensive care setting, quantitative and qualitative assessment of muscle function is challenging due to critical care environments (general anesthesia, altered consciousness, etc.). CT scan measurement at the 3rd lumbar level has been proposed to evaluate muscle function. Recent retrospective studies have highlighted increased mortality among patients with muscle mass impairment and/or decreased muscle density.
To date, no prospective study has assessed the prognostic value of CT scan measurements of muscle function upon admission to intensive care units for patients treated for septic shock. That is the aim of this project.
