Lung Ultrasound Versus Chest Radiography for Detection of Pneumothorax

Sponsor: Sunnybrook Health Sciences Centre

Summary

Sunnybrook Health Sciences Center annually provides assistance to approximately 600 cardiac surgeries and 1500 trauma patients, many of whom require chest tubes to prevent blood and fluids from accumulating in the pleural cavities surrounding the heart. During the removal of chest tubes, there is a risk of air leaking into these cavities, leading to pneumothorax, a critical condition occurring in approximately 5-26% of cases, associated with increased complications and mortality. Currently, the diagnosis of pneumothorax is primarily based on chest X-rays (CXR), despite their limitations and low reliability. As an alternative method, lung ultrasound (LUS) offers several advantages: it is safer, less expensive, and less painful for patients compared to CXR. However, there is a lack of comparative data on the accuracy and interrater reliability of these two diagnostic approaches after chest tube removal. This study aims to evaluate the accuracy of lung ultrasound performed by medical trainees in diagnosing pneumothorax in cardiac and trauma patients. By comparing LUS to CXR, the investigators seek to determine if LUS provides a more reliable and precise diagnosis. This study has the potential to enhance patient care by establishing a more effective and accessible method for diagnosing pneumothorax post-chest tube removal.
