Practice of ultrasound-guided central venous catheter technique by the French intensivists: a survey from the BoReal study group.

Background: The ultrasound (US)-guided technique has been recommended for central venous catheter (CVC) placement in critical care. However, several surveys have shown that the majority of physicians continue to perform landmark procedures. In our region, we have implemented special courses to promote the use of US with formal training and simulators.
