Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: CONTROL; In the CONTROL group, the administration of fluid (250-500ml crystalloids or colloids) and cardiovascular supportive drugs will be guided to maintain standard pressure-related parameters within a normal range: MAP > 65mmHg, HR < 90/min, CVP >8-12< cm H20, urinary output > 0.5 ml/kg/h. In line with the conventional approach, other physiological parameters will also be targeted: T° > 35.5°C, Sp02 > 95%, lactate < 2.5 mmol/L, normalisation of the BE. The maximal infused volume of hydroxyethyl starch (Voluven®) will be 33 ml/kg.	Other: CONTROL; In the CONTROL group, the administration of fluid (250-500ml crystalloids or colloids) and cardiovascular supportive drugs will be guided to maintain standard pressure-related parameters within a normal range: MAP > 65mmHg, HR < 90/min, CVP >8-12< cm H20, urinary output > 0.5 ml/kg/h. In line with the conventional approach, other physiological parameters will also be targeted: T° > 35.5°C, Sp02 > 95%, lactate < 2.5 mmol/L, normalisation of the BE. The maximal infused volume of hydroxyethyl starch (Voluven®) will be 33 ml/kg.; Other Names: Standard care; Vasopressors; trauma; fluide balance
Active Comparator: OPTIMIZED; In the OPTIMIZED group, the central venous catheter and the 4-French artery catheter (femoral or humeral access site) will be connected to a dedicated haemodynamic monitor (Pulsiocath, PV2024L; Pulsion Medical Systems AG, Munich, Germany). The administration of fluid (250-500ml crystalloids or colloids) and cardiovascular supportive drugs will be guided by an algorithm taking into account standard parameters (HR, MAP, lactate, Hb), as well as static and dynamic volumetric parameters (SVI, CI, GEDVI, EVLWI, SVV, PPV, PVI).	Other: OPTIMIZED; In the OPTIMIZED group, the central venous catheter and the 4-French artery catheter (femoral or humeral access site) will be connected to a dedicated haemodynamic monitor (Pulsiocath, PV2024L; Pulsion Medical Systems AG, Munich, Germany).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Delta lactate	The primary study endpoint will be the difference between the baseline arterial blood lactate at the time of randomization and the value of the arterial blood lactate at the time of transfer from the emergency operating room (∆ lactate).	From randomization, for the duration of surgery and up to transfer from the operating room to the ICU or recovery room, an expected average of 6 hours.

Secondary Outcome Measures
