简要总结
the purpose of this study is to assess the effect of norepinephrine and fluid expansion on capillary refill time during septic shock.
详细描述
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.

结局指标
主要结局
Difference of capillary refill time before and after the therapeutic change
时间窗: 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
Capillary refill time (CRT) is time required for return of color after application of blanching pressure to a distal capillary bed. In this study, we made a calibrated compression of the skin using a piston for seven seconds, and we recorded CRT with a smartphone's video camera.
次要结局
- Correlation between capillary refill time and perfusion index(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)
- Least significant change of capillary refill time(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)
- Difference between capillary refill time on thorax and on the index finger tip(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)
