Kozaci N, et al. - Bedside thoracic ultrasonography (TUSG) performed by emergency physicians with patients in the supine position was compared with that of thoracic computed tomography (TCT) in terms of accuracy for the determination of thoracic injuries due to trauma. Eighty-one trauma patients underwent TUSG followed by TCT imaging. TCT scans revealed subcutaneous emphysema in 16 (19.8%) patients, pneumothorax in 21 (25.9%), pulmonary contusions (PCs) in 27 (33.3%), hemothorax in 20 (24.7%), sternum and clavicular fractures in 6 (7.4%) and rib fractures in 21 (25.9%). Ultrasonography showed variable sensitivity and specificity for detecting the following pathologies: subcutaneous emphysema (56% and 95%), pneumothorax (86% and 97%), hemothorax (45% and 98%), PCs (63% and 91%), sternal fractures (83% and 97%), clavicular fractures (83% and 100%) and rib fractures (67% and 98%), respectively. Hence, for the identification of thoracic injuries, ultrasound is highly specific but is moderately sensitive.
