BackgroundWe aimed to show the sensitivity of Extended Focused Assessment with Sonography for Trauma (e-FAST) for detection of pneumothorax, hemothorax and intraabdominal injury. We also investigated the relationship between e-FAST and need for invasive treatment.MethodsThis study included patients who experienced multiple trauma. The emergency physician, who had no clinical information about the patient, performed e-FAST. Findings on a supine chest X-ray and invasive interventions were recorded. The results of abdomen and thorax computed tomography (CT) were reviewed (the size of the pneumothorax was scored).ResultsCompared with CT, the sensitivities of e-FAST for intraabdominal injury and hemothorax were 54.5% and 71%, respectively. The patients with hemothorax and intraabdominal injuries were not identified with e-FAST, didn't need for invasive intervention. Pneumothorax diagnosis was established in 27 patients with e-FAST (sensitivity 81.8%) from among 33 (30.8%) pneumothorax patients. According to the grading on CT, pneumothoraces less than 1 cm in width and not exceeding the midcoronal line in length were not identified. e-FAST was positive for all patients performed with tube thoracostomy.Conclusione-FAST can be used with high sensitivity for determination of pneumothorax requiring invasive procedure. It has low sensitivity in the diagnosis of intraabdominal injury and hemothorax; however, e-FAST can predict the need for invasive procedures.
