Diagnostic Accuracy of Ultrasound in the Detection of Pneumothorax in Chest Trauma Patients With Ct as the Gold Standard

Abstract

Background: To study the diagnostic accuracy of ultrasound in the detection of pneumothorax in chest trauma patients with CT as the Gold Standard
 Methods: The present study was conducted from 31th July 2018 to 30th July 2019. A total of 36 patients were enrolled in the study.
 Results: By chest ultrasound, pneumothorax was detected in 15 of 24 patients. The sensitivity of chest ultrasound for the diagnosis of pneumothorax was 62.5%, specificity was 100%, positive predictive value (PPV) was 100%, negative predictive value (NPV) was 54.14% and accuracy was 75%.
 Conclusion: Chest ultrasound can play an important role in the emergency department aiding a physician for bedside rapid and accurate diagnosis of pneumothorax without interruption in the resuscitation process and without transferring the patient to the radiology section.
