Study Arms:
- administration of norepinephrine by dynamic elastance (Type: EXPERIMENTAL): The norepinephrine weaning strategy is based on an index that reflects the vasomotor tone: dynamic arterial elastance
- control administration of norepinephrine (Type: OTHER): The usual procedure of withdrawal norepinephrine is based on hemodynamic parameters (blood pressure), clinical (cutaneous perfusion, mottling, hourly diuresis) and biological (SVO2, arterial lactate).

Based on this trial design, predict the completion outcome and termination type (if applicable).
