Central venous catheterization (CVC) of the subclavian or internal jugular veins is a common procedure performed in the emergency department (ED). This procedure is followed by complications in 0.3 to 12% of cases. Pneumothorax (PTX) and catheter-tip misplacement can occur. The diagnosis of these complications requires a chest radiograph (CXR). In certain cases, CXR may be time-consuming, requiring more than 30 minutes. This could be harmful in the case of critically ill patients. Moreover, several investigators have questioned the need of routine post-procedural CXR in the absence of clinical complications.
