Abstract

Objective: Despite the advantages of ultrasound scan, its use as a screening tool in blunt abdominal trauma is controversial. The aim of this study was to evaluate the diagnostic value of early and late ultrasound in patients with blunt abdominal trauma (BAT). Methods: In this study which was performed in a level I trauma center, firstly, 2418 patients with BAT had ultrasound (US) examination by two trauma expert radiologists. Results were compared with the best available gold standards such as laparotomy, CT, repeated ultrasound or clinical course follow-up. Then, 400 patients with BAT were examined by a trained residency student. Results: In the first phase, sensitivity, specificity, negative predictive value, positive predictive value and accuracy of ultrasound were 97, 98.1, 99.7, 83 and 98 respectively. In the second phase, they were 97.3, 97.2, 97.7, 96.8 and 97.3 for the early and 98.5, 97.6, 98.5, 97.5 and 98 for the late ultrasound respectively. Conclusion: Results obtained from this study indicate that negative ultrasound findings associated with negative clinical observation virtually exclude abdominal injury, and confirmation by performing other tests is unnecessary. High sensitivity and negative predictive value is achieved if ultrasound is performed by expert trauma radiologist. © 2015, Professional Medical Publications. All rights reserved.
