<b><span>Background:</span></b><span> Blunt thoracic and abdominal traumas are frequent and have a poor prognosis in the absence of prompt diagnosis and adequate management. An ultrasound performed in the emergency room allows a precise diagnosis and a better orientation of the victims.</span><span> </span><b><span>Objective:</span></b><span> To assess the contribution of EFAST ultrasound in the management of blunt thoracic and abdominal traumas.</span><span> </span><b><span>Patients and method:</span></b><span> Cross-sectional descriptive and analytical study with prospective data collection carried out from February 20</span><sup><span style="vertical-align:super;">th</span></sup><span> to August 20</span><sup><span style="vertical-align:super;">th</span></sup><span>, 2017 in the emergency and intensive care units of the Parakou University Hospital Centre. An ultrasound machine fitted with a 3.5 MHz convex probe was used to search for post-traumatic effusion by the EFAST technique on admission and then as needed over 24 hours and after surgery.</span><span> </span><b><span>Results:</span></b><span> Sixty-three patients were collected with an 85.71% male predominance. The average age was 31.36 ± 13.29 years. The time to perform the EFAST ultrasound was 7 ± 3 min. EFAST was positive in 50.79% of patients. Five patients (7.93%) received emergency treatment for hemodynamic instability and positive EFAST within an average of 3.46 ± 2 hours. Eighteen patients (27.58%) received after monitoring by EFAST, surgery within 9 hours 12 minutes (hemoperitoneum) and 27 hours 58 minutes (hemothorax). Two patients were tested positive</span><span>ly</span><span> for EFAST after surgery.</span><span> </span><b><span>Conclusion:</span></b><span> The introduction of an EFAST ultrasound as a sorting tool in an environment with limited resources is desirable and feasible.</span>
