Septic shock remains a major public health problem in industrialized countries, with a mortality rate as high as 50%, largely related to multiple organ dysfunction. In addition to dysregulated inflammatory response, the pathophysiology of organ failures in septic shock involves ischemia-reperfusion processes. Remote ischemic conditioning is a therapeutic strategy for protecting organs against the detrimental effects of ischemia-reperfusion injury.

The objective of the present study is to determine whether remote ischemic conditioning can limit the severity of organ failure in patients with septic shock.

• Lactatemia > 2 mmol/L at least once in the past 12 hours before inclusion
• Written informed consent signed by the patient or by a next of kin or oral consent given by the patient and as soon as permitted by the clinical state written informed consent signed by the patient.
