| Abstract | ||||
| Background: Traumatic pneumothorax is a life-threatening condition that may occur in patients with blunt or penetrating chest trauma. Traumatic pneumothorax has different degrees ranges from traumatic occult pneumothorax (TOP) to tension pneumothorax. Early detection of TOP is crucial to predict patients in risk for development of significant pneumothorax and improve patient’s outcome. Bedside ultrasonography (US) has emerged as a valuable tool in the emergency department (ED) for the detection of TOP. Objective: This research aimed to evaluate the diagnostic accuracy of bedside US in detecting traumatic occult pneumothorax in patients with chest trauma. Patients and Methods: We conducted a prospective study on 150 patients with chest trauma who underwent both chest ultrasonography and computed tomography (CT) scans. The primary outcome measure was the sensitivity and specificity of bedside US in detecting TOP. Results: The results showed that bedside US had a sensitivity of 80.99% (95% CI: 72.86% to 87.55%) and specificity of 96.09% (95% CI: 92.11% to 98.41%) to detect TOP. Conclusion: Our study suggests that bedside chest ultrasonography is a reliable tool for the detection of TOP. The high sensitivity and specificity of bedside chest US make it a valuable addition to the diagnostic armamentarium in the ED. Early detection of TOP using bedside chest US can lead to timely intervention and improved patient’s outcome. | ||||
