Ultrasound-guided central venous cannulation is superior to quick-look ultrasound and landmark methods among inexperienced operators: a prospective randomized study.

Objective: Quick-look ultrasound with a skin mark (UM) has been frequently used for central vein cannulation. The aim of this study is to compare this method with landmark (LM) and ultrasound-guided (UG) cannulation of jugular and femoral veins by inexperienced operators.

Design: Prospective randomized single-center study.
