Ultrasound to confirm needle, wire, and catheter position in the vein. Ultrasound images during real-time ultrasound-guided central venous catheter placement in the right internal jugular vein. Ultrasound guidance should include confirmation of the needle position in the vein before approaching the guide wire (short-axis/out-of-plane view (a) and long-axis/in-plane view (b)). In addition, the correct position of the guide wire in the vein (short-axis (c) and long-axis (d)) and the correct position of the catheter in the vein (short-axis (e) and long-axis (f)) should be confirmed
