The ultrasound guidance has greatly reduced installation times, failures and complications related to the set-up of central venous catheter. This was amply demonstrated in the internal jugular and subclavian site outside of extreme emergency situations (Fragou M et al 2011, Farrell J et al 1997, Karakistos et al 2006). The benefit of ultrasound guidance for the set-up of arterial and venous catheters in the femoral emergency has not been evaluated in terms of reduction in complications.
