Abstract: Background: We evaluated whether a simulation-based training with a vessel phantom improves the basic skills of a novice required for ultrasound-guided radial artery cannulation in real patients. In addition, we analysed whether repeated simulation training sets with an inter-training interval would accelerate the learning curve. Methods: From March 2019 to July 2019, twenty-one anesthesiology residents were randomized into either a simulation group (n = 11) or control group (n = 10). Residents performed a total of 84 ultrasound-guided radial artery cannulations in real patients. The simulation group participated in two sets of simulation training on a vessel phantom (10 sessions per set) with a one-month inter-training interval. Trainee’s performance proficiency was scored using a developed checklist, and a learning curve for each training set was constructed. To evaluate the effectiveness of our training curriculum in skill transfer, each resident performed four ultrasound-guided radial artery cannulations in real patients. The primary outcome was first attempt success rate and the secondary outcome was dynamic needle-tip positioning ability in real patients. Results: The first attempt success rate and dynamic needle-tip positioning ability by ultrasound transducer were significantly higher in the simulation group than the control group (81.8% vs. 50%, P = 0.002 and 68.2% vs. 7.5%, P
