“…Thus, in this US-guided CVC training program, A subtle difference between the bench model described here and other similar previously presented simulators 2,10 is that our modified bench model followed a standard guideline for the production of ballistic gelatin 21 . Thus, besides the ease of manufacture and reproduction, homogeneous quality can be easily reached by anyone (resident-in-training or instructor) who is preparing the simulator based on the ballistic gelatin concept 21 . These gelatin bench models suffer from lack of opacity and echogenicity and it can be reduced with the use of graphite powder, millet flour, or dietary fiber supplement, as in our modified bench model.…”

“…The choice between these cylindrical materials must be cost-based. During the training process we found that the ballistic gelatin bench model could be rapidly and reproducibly generated if the method previously described 21 was closely followed. All residents involved in the training were able to fabricate their own bench models and bring them to the teaching and learning sessions ( Figure 1).…”

“…As the development of an alternative bench model allowing US-guided CVC training in a reliable, reproducible, and inexpensive fashion would be extremely valuable for disseminating and facilitating the US-guided CVC teaching and learning, we adapted a homemade low-fidelity gelatin bench model with inspiration on the ballistic gelatin concept 21 . Ballistic gelatin has physical characteristics that accurately simulate the strength and viscosity of human tissues, making it useful in wound ballistic experiments as a tissue surrogate 21 .…”

“…Ballistic gelatin has physical characteristics that accurately simulate the strength and viscosity of human tissues, making it useful in wound ballistic experiments as a tissue surrogate 21 . Besides being well established as soft-tissue substitute in ballistic tissue injury research 21 , ballistic gelatin has served as an excellent surrogate tissue providing an easily manufactured, reproducible, and inexpensive model for a number of purposes 22 .…”

PURPOSE:To propose a simulation-based ultrasound-guided central venous cannulation skills' training program, during residency. METHODS:This study describes the strategies for learning the ultrasound-guided central venous cannulation on low-fidelity bench models. The preparation of bench models, educational goals, processes of skill acquisition, feedback and evaluation methods were also outlined. The training program was based on key references to the subject. RESULTS:It was formulated a simulation-based ultrasound-guided central venous cannulation teaching program on low-fidelity bench models. CONCLUSION:A simulation-based inexpensive, low-stress, no-risk learning program on low-fidelity bench models was proposed to facilitate acquisition of ultrasound-guided central venous cannulation skills by residents-in-training before exposure to the living patient.

Ballistic gelatin is widely used as a soft tissue simulant for non-penetrating and penetrating, and the mechanical properties of gelatin are known to be highly sensitive to strain rate and temperature. Mechanical compression testing was undertaken across a range of strain rates at constant temperature to evaluate the material response. The material strength and stiffness increased with increasing strain rate, while the strain to failure was relatively constant across a wide range strain rates. The mechanical test data was implemented in two constitutive models: a quasi-linear viscoelastic model, commonly available in explicit finite element codes, and a tabulated hyperelasticity model. The implementations were verified using simulations of the experimental tests and it was found that the quasi-linear viscoelasticity model did not adequately capture the low and high strain rate response across the range of data. The tabulated hyperelasticity model was found to provide accurate representation of the material across the range of strain rates considered, and included a damage function to predict material failure.
