Brief Summary:
The purpose of this study is to determine if emergency room physicians can use bedside ultrasound to quickly determine the proper placement of a central venous catheter and to evaluate for complications such as a punctured lung.

Condition or disease Intervention/treatment Phase
Catheterization, Central Venous Procedure: Ultrasound Not Applicable

Detailed Description:

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.

Recent data has shown that ultrasound can accurately detect PTX in critically ill patients. Furthermore, bedside ultrasound is an easy technique to investigate the subclavian and internal jugular veins, and can improve the success rate of catheter insertion. Ultrasound also allows visualization of central venous catheters in vivo. Ultrasound has been reported as a tool to detect catheterization complications and misplacement when performed by ICU physicians, but has never been studied in the ED.

This method could be valuable in hemodynamically unstable patients, who quickly need a CVC for the measurement of central venous pressure, immediate fluid resuscitation, and infusion of vasoactive medications. Similarly, bedside ultrasound examination could quickly confirm PTX and allow immediate chest tube insertion in case of respiratory distress after catheter insertion.

We hypothesize that bedside ultrasound examination performed by ED physicians could accurately detect placement of the CVC and the presence or absence of a PTX after catheterization of the jugular and subclavian veins.
