eFast Diagnosis Performance in Guiding First Aid Resuscitation

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.
