Objective To assess the value of emergency ultrasound in the diagnosis of patients with abdominal trauma. Methods Retrospective study was performed on 245 patients with abdominal trauma. All patients were examined with emergency ultrasound, and their sonographic findings were compared with their CT and operative findings. Results 1) Abnormal signs suggestive of injury were detected in 346 organs among 245 patients, and correct diagnosis was made in 299 cases, while misdiagnosis occurred in 47. The overall accuracy of sonographic diagnosis was 86.4%. 2) The accuracy rate of sonographic diagnosis of various organs: for splecn, liver, kidney, mesentery, bladder, retroperitoneal injuries were 93.4%, 91.9%, 80.9% and 51.3% respectively. 3) The accuracy of sonography on the free fluid and retroperitoneal fluid were 100% (213/213) and 89.5% (51/57) respectively. Conclusion Emergency sonography to evaluate patients for injury caused by abdominal trauma is highly accurate.
