Practical aspects of ultrasound-guided central venous catheter placement in the internal jugular vein using the "single-operator technique”. An aseptic approach including covering the puncture site with a large sterile drape, using sterile barriers (hat, mask, sterile gloves, sterile body gown), and covering the ultrasound probe and cable with a sterile cover is shown. The position of the operator (who holds the ultrasound probe with the nondominant hand while advancing the needle with the dominant hand) allows aligning the insertion site, the needle, and the ultrasound screen in the line of sight during needle insertion (red lines) (Color figure online)
