The main objectives of the study are 1)to examine the immediate (2 hours) and delayed (8 hours) effects of intravenous hydrocortison on macro and microvascular post-ischemic vasoreactivity, in septic shock adult patients; 2) to examine possible correlations between post-ischemic flow-mediated dilation (FMD) of the brachial artery (assessed by ultrasound imaging) and post-ischemic recovery slope of the thenar oxygen saturation (StO2) (assessed by near-infrared spectroscopy).
Two primary end points, considered as reflecting vasoreactivity will be assessed :

Flow-mediated dilation (FMD) of the brachial artery, measured by ultrasound imaging, expressed in mm or in percentage, will be calculated from artery diameters measured before and after a vascular occlusion test (cuff around arm or forearm).
recovery slope of thenar oxygen saturation (StO2), assessed by near infrared spectroscopy (NIRS), expressed in %/second, will be recorded after the vascular occlusion test.

The two primary end points (FMD and recovery slope of StO2)will be assessed at the following timepoints :

baseline (before first injection of placebo or hydrocortison)
2 hours after first injection of placebo or hydrocortison
2 hours after second injection of placebo or hydrocortison (i.e. 8 hours after first injection)
4 to 6 hours after third injection
4 to 6 hours after fourth injection (optional)
