Arm Description
non-septic mesocolic programmed abdominal or thoracic surgery: gastrectomy, esophagectomy, pancreatectomy, hepatectomy
Abdominal or thoracic surgery in a septic context (peritonitis, mediastinitis, pleural abscess)
Patient in brain death for whom a multi-organ sampling is planned
Patient under controlled mechanical ventilation to undergo abdominal or thoracic surgery in a septic context (peritonitis, mediastinitis, pleural abscess)
Outcomes
Primary Outcome Measures
Assessment of atrophy of the myofibers of the human diaphragm
Atrophy of the myofibers will be assessed by comparison of the cross sectional area of the three different types of myofibers between the sepsis-mechanical ventilation group and the sepsis group, the ventilation group and the control group

5. Study Description
Brief Summary
The aim of this study is to study the combined impact of mechanical ventilation and sepsis on the human diaphragm in order to establish the neutral, protective or destructive character of mechanical ventilation by studying the diameter of the fibers, activation of proteolytic systems, inhibition of protein synthesis, tissue inflammation as well as contractile function.
