This study compares the safety and efficacy of GDTs using standard pressure-related parameters vs. dynamic hemodynamic indices associated with fluid compartment monitoring, in trauma patients requiring emergency surgery.

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.
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).

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).
Time frame: 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.
Cardiovascular complications: myocardial infarct or congestive heart failure
Clinical outcome and surrogate biomarkers (Troponin-I and pro-BNP: day 1-2-3) will be recorded by extracting this specific data from the electronic medical file, until discharge, death or up to 28 days, whichever comes first.
Time frame: Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.
