BACKGROUND: Ultrasound training requires proper instruction and guidance tailored both to novice and advanced ultrasound users. The aim of the current investigation was to compare the performance of novice and advanced sonographers using a tofu model for IV cannula placement using either ultrasound static (US) or dynamic (UD) techniques. METHODS: Eighty volunteers were allocated to either the novice or advanced group according to prior ultrasonography experience. Participants were randomly assigned (1:1) to either the US or UD group. A modified version of the global rating scale was used to assess performance. The primary outcome was the assessment scale composite score. Secondary outcomes included time to procedure completion and the number of needle passes. RESULTS: In the novice cohort, the US group scored significantly higher than participants in the UD, median difference 9 (95% CI: 0-19), CONCLUSION: Compared to the real time UD method, the US technique for intravenous cannulation is more fitted for novice users and should be considered more widely as the introductory technique to improve their procedural efficiency of ultrasound guided intravenous cannulation.
