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

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.
