<qa>  What is the efficacy of the proposed measures?Early and adequate fluid resuscitation 6 hours in patients with circulatory failure is essential but may exacerbate oedema, which may itself: 1 aggravate pulmonary lesions and prolong mechanical ventilation, 2 aggravate organ failure and 3 increase mortality notably in patients with acute renal failure. Improving fluid balance is considered crucial in the management of patients in septic shock, but the efficacy of the measures currently proposed diuretics associated or not with albumin andor dialysis is controversial. The investigators hypothesize that a whole-body compression using a body bandage could reduce capillary leakage and thus lead to faster restoration of a normal transmural pressure gradient in postcapillary venules and improve venous return.
