Sedation Optimisation Strategy (S.O.S.) Ventilation

Use of sedatives and analgesics is common in mechanically ventilated patients hospitalized in Intensive Care Unit (ICU). That is called \" sedation \" and aimed to reduce both pain and anxiety and also to allow an effective and atraumatic mechanical ventilation. However, sedation excess and ventilator support excess, both in duration and intensity, are associated with an excess morbidity. Patients usually are systematically sedated after having been intubated. Then, sedation is stopped first before ventilator support is weaning. Several studies shown that rationalized protocols of sedation and ventilation orderings had a beneficial impact on non surgical patients\' outcome. Feasibility of these protocols in surgical patients is still unknown. Moreover, no study has evaluated an optimized paired strategy of sedation-ventilation based on the priority setting of ventilation. This priority setting of ventilation should increase patient\'s comfort in spite of increasing sedatives and analgesics dosing. An paired sedation-ventilation protocol optimized for both duration and intensity of these treatments could improve surgical patients\' outcome in ICU.
