Impact of Early Goal-directed Fluid Therapy in Hypovolemic Patients Undergoing Emergency Surgery
Study Details
Study Description
Brief Summary
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.

| 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. |

| 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). |

Outcome Measures
Primary Outcome Measures
- Delta 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.]
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).
Secondary Outcome Measures
- Cardiovascular complications: myocardial infarct or congestive heart failure [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
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.
- Cerebral complications: stroke [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcomes at day 1-2-3 will be recorded by extracting this specific data from the electronic medical file, and until discharge, death or up to 28 days, whichever comes first.
- Pulmonary complications: ALI/ARDS, bronchopneumonia [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcomes at day 1-2-3 will be recorded by extracting this specific data from the electronic medical file, and until discharge, death or up to 28 days, whichever comes first.
- Pulmonary complications: respiratory insufficiency necessitating re-intubation [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcomes at day 1-2-3 will be recorded by extracting this specific data from the electronic medical file, and until discharge, death or up to 28 days, whichever comes first.
- Surgical complications: re-operation for bleeding or infection [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcomes at day 1-2-3 will be recorded by extracting this specific data from the electronic medical file, and until discharge, death or up to 28 days, whichever comes first.
- Renal complications: infection, urosepsis or renal insufficiency [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcome and surrogate biomarkers (Riffle score, creatinine: 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.
- Duration of post-operative mechanical ventilation: in hours [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcomes at day 1-2-3 will be recorded by extracting this specific data from the electronic medical file, and until discharge, death or up to 28 days, whichever comes first.
- Total duration of ventilation : days [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
Clinical outcomes (ventilation free days) will be recorded by extracting this specific data from the electronic medical file, and until discharge, death or up to 28 days, whichever comes first.
- Length of stay in the ICU: in days [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
- Length of stay in hospital: in days [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
- Mortality [From randomization up to 28 days]
- SOFA score measurement [From randomization : day 1, day 2, day 3]
- Death [Day 1, day 2, day 3 after randomization until hospital discharge or up to 28 days or death, whichever comes first.]
- Number of unexpected ICU admission [From randomization up to 28 days]
