Background: Chest trauma is responsible for more than 20 to 25% of all traumatic death. Chest trauma is the second leading cause of traumatic death in each year. In order to keep the prognosis of patients with chest trauma relatively good, the patient should be diagnosed rapidly & managed adequately. Chest ultrasound is a safe, rapid and accurate method in diagnosing chest trauma.Methods: A total of 50 patients were enrolled in this study. Objectives were to assess the accuracy of bedside chest US in detection of either haemothorax, pneumothorax or lung contusion in chest trauma patients. All the patients underwent chest US, CXR, and chest CT. The data from ultrasound and CXR were compared with the gold standard CT. Then the accuracy of which were calculated.Results: Showed that Motorcar accidents are the most common cause for chest trauma and most patients were presented by chest pain and dyspnea. Chest ultrasound specificity in diagnosing pneumothorax was higher than sensitivity, 100% and 81% respectively, with over all accuracy 88%. Supine CXR showed sensitivity (75%), specificity (88.9%) and accuracy (80%) which are good numbers but still lower than chest US. Chest US Detection of haemothorax by chest had showed 100% sensitivity, 90% specificity and 96% accuracy.Conclusions: Chest ultrasound is highly accurate tool for detection of pneumothorax, haemothorax and less lung contusion in chest trauma. Chest ultrasound is a useful tool for the emergency physician for bedside rapid and accurate diagnosis without interruption of the resuscitation and without transferring the patient for the radiology unit.
