Review Meta Analysis Comparative Study
Test characteristics of ultrasonography for the detection of pneumothorax: a systematic review and meta-analysis.
A pneumothorax is a potentially life-threatening condition. Although CT scan is the reference standard for diagnosis, chest radiographs are commonly used to rule out the diagnosis. We compared the test characteristics of ultrasonography and supine chest radiography in adult patients clinically suspected of having a pneumothorax, using CT scan or release of air on chest tube placement as reference standard. ⋯ Performance of ultrasonography for the detection of pneumothorax is excellent and is superior to supine chest radiography. Considering the rapid access to bedside ultrasonography and the excellent performance of this simple test, this study supports the routine use of ultrasonography for the detection of pneumothorax.
