eFast Diagnosis Performance in Guiding First Aid Resuscitation

Study Overview
=================
Brief Summary
-----------------
A lesion work-up associating clinical examination, extended focused ultrasound (eFAST including abdominal ultrasound [right upper, left upper, and suprapubic quadrant], bilateral anterior and lateral pleuropulmonary ultrasound, sub-xyphoid pericardial ultrasound, transcranial Doppler), and possibly chest and pelvis x-ray, can early diagnose the most severe traumatic lesions and guide first aid resuscitation and haemostasis. The protocol does not modify the diagnostic and therapeutic strategies applied in the participant centers. The objective of the study is to evaluate the diagnosis performance of an initial lesion assessment by extended focused ultrasound (eFAST) (possibly associated with chest and pelvis x-ray) at the early phase of a severe trauma patient care in guiding first aid resuscitation and haemostasis. The relevance will be judged on the therapeutic decisions taken (thoracic or pericardial drainage, thoracotomy or laparotomy, pelvic embolization, posture of a pelvic girdle, and early optimization of cerebral perfusion pressure) based on the initial ultrasound scan.

Detailed Description
-----------------
Some of the severe traumatized patients who arrive alive in the hospital, are in serious hemodynamic and / or respiratory instability and need resuscitation and / or hemostasis immediate act before a complete exhaustive work-up can be realized. Usually this is a whole body CT scan. These gestures are guided by imaging examinations (extensive focused ultrasound [eFAST] +/- chest X-ray +/- pelvis X-ray) which are less accurate but faster at the patient's bedside. The ability of extended focused ultrasound to properly guide immediate resuscitation and hemostasis should be evaluated to assess effectiveness and safety of the method. This trial is a national prospective cohort (6 French centers). Each participant will benefit from an initial lesion work-up by clinical examination, followed by an extended focused ultrasound (eFAST including abdominal ultrasound [right upper, left upper, and suprapubic quadrant], bilateral anterior and lateral pleuropulmonary ultrasound, sub-xyphoid pericardial ultrasound, transcranial Doppler), and possibly chest and pelvis frontal x-ray. Based on clinical, radiographic and ultrasound data, the investigator will decide to perform immediate resuscitation and haemostasis gestures, or therapeutic abstention, before the realization of the complete lesion work-up by whole body CT scan. This study could validate and strengthen the place of ultrasound in the initial severe traumatic patients' care and seems to be the continuity of the Peytel et al. research, studying new modalities of the eFAST. Our study could extend the scope and the conclusions of the Peytel et al. study to what is routinely done in the French and European Trauma Centers.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the diagnosis performance of an initial lesion assessment by extended focused ultrasound (eFAST) at the early phase of a severe trauma patient care in guiding first aid resuscitation and haemostasis. | Retrospective assessment (on whole-body CT scans data and clinical data), by a panel of experts on the legitimacy of urgent therapeutic decisions taken, following the initial injury evaluation (among a pre-selection of decisions). Assessment of presence of pericardic, intra-abdominal or pleural effusion and presence of pubic symphisis. Assessment of physiological parameters of transcranial Doppler. | Through study completion, an average of 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the duration of the initial lesion assessment by extended focused ultrasound (eFAST). | Time measured between the arrival of the patient in the emergency room and the realization of immediate gestures of resuscitation and haemostasis | A Day 0 | 
| Analysis of the main outcome measure in separate criterion: US (+/- Rx). | Analysis of the relevance of ultrasound vs X-rays by assessing the concordance rate between urgent therapeutic decisions and expert evaluations for each of the therapeutic modalities, taken separately | Through study completion, an average of 1 year |
