International guidelines advocate the use of first-line ultrasound for central venous catheter, particularly for the internal jugular vein.

The role of ultrasound in peripheral venous access remains questionable. In some specific situations, such as pediatrics, obesity and patients with poor venous network, problems to cannulate peripheral vein may occur. Success rate of peripheral intravenous access increases with the diameter of the vein and for a depth of the vein between 0.3 and 1.5cm. The type of puncture (long-axis or short-axis) and the type of catheters have little influence on the success rate. Specific considerations have to be taken concerning infection control.
