Chest Ultrasound Versus Chest X-ray with Ct As Gold Standard At Trauma Patients

Diagnostic Accuracy of Chest Ultrasonography Vs. Chest X-ray in the Evaluation of Chest Trauma: a Comparative Study Using CT As the Gold Standard.

The goal of this observational study is to learn about the predictive value of the chest ultrasound in detection of pneumothorax at chest trauma patients.

The main question it aims to answer is:

How does the performance of the chest ultrasound compare to chest X-ray in predicting pneumothorax in chest trauma patients in Egypt? Participants are patients with different ages Isolated blunt chest trauma patients admitted to the emergency department during the study period.

Study Overview

• Status: Not yet recruiting
• Conditions: Pneumothorax At Trauma Patients

Detailed Description

Chest trauma is a leading cause of morbidity and mortality, with timely and accurate diagnosis essential for effective treatment. While chest X-ray (CXR) has traditionally been the first-line imaging modality in emergency settings due to its availability and ease of use, it has limitations, particularly in detecting subtle or occult injuries like pneumothorax, haemothorax, rib fractures, and pulmonary contusions, especially in trauma patients positioned supine. Overuse of CXR can also lead to increased costs, radiation exposure, and emergency department overcrowding.

Ultrasound has emerged as an alternative, with multiple studies showing that chest ultrasonography (CUS) is highly sensitive and specific for detecting traumatic intrathoracic injuries, including pneumothorax. This systematic review and meta-analysis aimed to assess the diagnostic accuracy of CUS compared to CXR. While CT scans remain the gold standard for diagnosing thoracic trauma due to their superior accuracy, they expose patients to significant radiation and should be used judiciously. Although CXR is a fast and accessible option in emergencies, it may miss critical injuries, highlighting the importance of balancing diagnostic accuracy with patient safety and resource management in trauma care.

The primary aim of this study is to evaluate and compare the diagnostic accuracy of chest ultrasonography (sonar) versus chest X-ray (CXR) in the detection of thoracic injuries in patients presenting with chest trauma, using computed tomography (CT) as the reference standard.
