Poly-trauma patients are people who are suffering from two or more severe injuries in at least two body areas or, two or more severe injuries in one body area. Worldwide, about 1.2 million people die in Road Traffic Accidents (RTA) annually and about 50 million are injured. In Egypt, about 12000 deaths due to RTA annually with a road traffic fatality rate of 42 deaths per 100000 population.RTA is neither unpredictable nor unpreventable. Appropriate prevention and management strategy implementation can save many lives.
Ultrasound provides an important initial screening tool for assessment of poly-trauma patients. Ultrasound has considerable advantages as it is a non-invasive bedside tool, easy to use, inexpensive, time saver with real time imaging. And also employs no radiation or contrast agents. Since 2004, the E-FAST protocol was developed to detect pneumothorax, intrathoracic and intraperitoneal fluid with a high specificity and sensitivity. Lung contusion (LC) is a common clinical entity in blunt chest trauma and is associated with a 10–25 % mortality rate. Despite its relatively high incidence, it is difficult to identify LCs in the ED as traditional radiology will underestimate its prevalence. For this reason, a new protocol; Chest Abdominal FAST (CA-FAST) that integrates the detection of LCs in the E-FAST examination has been developed.
