Brief summary: the purpose of this study is to assess the effect of norepinephrine and fluid expansion on capillary refill time during septic shock.

Detailed description: An interventional study compared, in septic shock, the effect of resuscitation strategy targeting normalization of capillary refill time versus strategy targeting serum lactate level. This last highlight a decrease of organ dysfunction at 72 hours with capillary refill time strategy and non-significant trend towards lower 28-day mortality in the capillary refill time strategy group.

The strategy guided by the decreasing of capillary refill time allowed the administration of less fluid than that guided by lactate. This is an important advantage when the intensive care doctor know that the mortality of patient in septic shock increases with the amount of fluid administered.

However, the variations of capillary refill time induced by the principal treatment in septic shock (norepinephrine and fluid resuscitation) during circulatory failure are actually insufficiently described. The purpose of this study is to assess the effect of norepinephrine and fluid expansion on capillary refill time during septic shock.

Eligibility criteria: Inclusion Criteria:

* Septic shock
* Presence of a cardiac output monitoring
* Decision by the physician in charge to perform vascular filling or modification the norepinephrine dose

Exclusion Criteria:

* Patient under a tutelage measure or placed under judicial protection

Primary outcomes:
measure: Difference of capillary refill time before and after the therapeutic change
timeFrame: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
Secondary outcomes:
measure: Correlation between capillary refill time and perfusion index
timeFrame: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
measure: Least significant change of capillary refill time
timeFrame: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
measure: Difference between capillary refill time on thorax and on the index finger tip
timeFrame: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
