“…A variety of models with similar purposes were presented in the contemporary medical literature; the models differ in relation to the level of delity when compared to a human body [20,21,22]. Working on low-cost models favors the training of basic skills during undergraduate training in health sciences, a way to partially reduce costs, especially in developing countries [23,24].…”

Background: Realistic simulation methodology is used in various learning scenarios, allowing students to participate directly in problematic situations that require immediate professional action. The objective of this proof-of-concept study was to develop a low-cost simulator for cardiopulmonary resuscitation procedures in infants.Findings: The prototype was developed successfully with accessories to simulate cardiopulmonary resuscitation maneuvers. The data collection instrument was a questionnaire based on the Basic Life Support guidelines of the American Heart Association to test the instrument. The prototype was used as a learning object for the teaching-learning process as a low-cost resource.Conclusion: A low-cost prototype was developed, and its application was obtained from the simulation of the training activity in Basic Life Support and from the performance of procedures in the positioning and simulation of cardiopulmonary resuscitation.

“…10 Many models have been developed with the aim of simulating medical procedures, but the majority of them bear very little similarity to what is found in real patients. 11,12 With the aim of improving the range of models available, by achieving a closer approximation to reality, this study consisted of creation of a model made from gelatin that could be used to train ultrasound-guided punctures, both transversally and longitudinally.…”

BACKGROUND: It is indispensable that members of the medical profession receive the technical training needed to enable them to rapidly obtain effective vascular access. Training procedures should be used judiciously to familiarize students with the technique. However, existing models are expensive or ineffective, and models need to be developed that are similar to what will be encountered in real patients.OBJECTIVES: To demonstrate creation and application of a gelatin model for training ultrasound-guided puncture.METHOS: The model was made using a mixture of colorless gelatin and water in a transparent plastic receptacle with two pairs of orifices of different diameters, through which two plastic tubes were inserted, to simulate blood vessels.RESULTS: The model was a close approximation to the real medical procedure in several aspects, since gelatin has a similar consistency to human tissues, providing a more faithful reproduction of the tactile sensation at the moment when the needle reaches the interior of a vessel and its contents are aspirated.CONCLUSIONS: The method proposed here can be used to easily construct a low-cost model using everyday materials that is suitable for large-scale training of ultrasound-guided puncture.

“…With the teacher as the primary factor in learning, able to define personality and show the paths to knowledge, it is important to be capable of recognizing new teaching methods, and then integrate them into already used ones, to enable the student to be more active in the process of building their knowledge 14 . The acquirement of methods in conjunction is superior to any that acts singularly 1 , 14.…”

“…Similar methods have been used in other studies, in medicine and other areas, with good results. According to the authors, such methods favor learning, reduce the number of errors during practice, with a significant improvement in the performance of those who were exposed to videos as well as greater satisfaction and acceptance by the target audience 5 , 16 , 1 , 10 6, 7 . It is assumed that the use of this visual resource can be beneficial for the understanding of the surgical technique, since it integrates the image of the teacher to the practical demonstration of the procedure, in great detail, illustrating and providing technical and scientific subsidies.…”

Background: The development of didactic means to create opportunities to permit complete and repetitive viewing of surgical procedures is of great importance nowadays due to the increasing difficulty of doing in vivo training. Thus, audiovisual resources favor the maximization of living resources used in education, and minimize problems arising only with verbalism. Aim: To evaluate the use of digital video as a pedagogical strategy in surgical technique teaching in medical education. Methods: Cross-sectional study with 48 students of the third year of medicine, when studying in the surgical technique discipline. They were divided into two groups with 12 in pairs, both subject to the conventional method of teaching, and one of them also exposed to alternative method (video) showing the technical details. All students did phlebotomy in the experimental laboratory, with evaluation and assistance of the teacher/monitor while running. Finally, they answered a self-administered questionnaire related to teaching method when performing the operation. Results: Most of those who did not watch the video took longer time to execute the procedure, did more questions and needed more faculty assistance. The total exposed to video followed the chronology of implementation and approved the new method; 95.83% felt able to repeat the procedure by themselves, and 62.5% of those students that only had the conventional method reported having regular capacity of technique assimilation. In both groups mentioned having regular difficulty, but those who have not seen the video had more difficulty in performing the technique. Conclusion: The traditional method of teaching associated with the video favored the ability to understand and transmitted safety, particularly because it is activity that requires technical skill. The technique with video visualization motivated and arouse interest, facilitated the understanding and memorization of the steps for procedure implementation, benefiting the students performance.
