It is highly sensitive and specific if performed by experienced physicians. The most complex part of the learning curve is represented by the acquisition of adequate images for diagnostic purposes. Hence it is of primary importance to properly handle the ultrasound probe and to identify its correct position and orientation on patients. High fidelity simulation (HFS) might provide an efficient way of learning by reproducing realistic and rare situations. However, although some ultrasound simulators are commercially available, none is of low cost, suitable for every medical discipline and specifically designed for HFS and made for any mannequin. Objective The purpose of this study was to evaluate the use of an ultrasound simulator specifically designed for HFS during FAST exam. Patients and methods This prospective study involved first- and second-year anesthesiology residents, without prior FAST training. Participants were randomly divided in two groups. The first group was trained by a standardized 2-hours didactic lecture about FAST exam, while the other was given 2-hours training using an innovative, versatile, low budget ultrasound simulator, specifically designed by our researchers. Both groups were trained by the same instructor and the same images were used. Then both groups practiced a FAST exam on a real multiple trauma * Correspondence: [email protected] Department of Morphology, Surgery and Experimental Medicine, Section of Anesthesia and Intensive Care, University of Ferrara, Ferrara, Italy
patient. Four procedures were recorded: correct probe position, time to images acquisition, quality of images and their interpretation.
Results 20 residents were enrolled, ten each group. All participants were able to obtain FAST images, but residents using the simulator were faster than those trained with the traditional lecture: 3.4 ± 0.7 and 4.3 ± 1.1 min, respectively (p
