ABSTRACT
ABSTRACT Background: Three-dimensional videosurgery is already a reality worldwide. The trainee program for this procedure should be done initially and preferably in simulators. Aim: Assemble low-cost simulator for three-dimensional videosurgery training. Methods: The simulator presented here was mounted in two parts, base and glasses. After, several stations can be inserted into the simulator for skills training in videosurgery. Results: It was possible to set up three dimensional (3D) video simulations with low cost. It has proved to be easy to assemble and allows the training surgeon of various video surgical skills. Conclusion: This equipment may be used in undergraduate programs and advanced courses for residents and surgeons. The acrylic box allows the visualization of the task executed by the tutor and even by other experienced students.
RESUMO Racional: A videocirurgia em três dimensões já é realidade no cenário atual. O treinamento dessa habilidade deve ser feito inicialmente e preferencialmente em simuladores. Objetivo: Montar simulador de baixo custo para treinamento de videocirurgia em três dimensões. Métodos: O simulador aqui apresentado foi montado em duas partes, base e óculos. Após montagem, podem ser inseridas estações diversas no simulador para treinamento de habilidades em videocirurgia. Resultados: Foi possível montar simuladores de videocirurgia em 3D com custo baixo. Ele apresentou-se ser de fácil montagem permitindo o treinamento de várias habilidades videocirúrgicas. Conclusão: Este equipamento pode ser utilizado tanto em cursos básicos para a graduação quanto para avançados destinados a residentes e cirurgiões. A caixa de acrílico permite a visualização da tarefa executada pelo orientador/tutor e por outros alunos.

PURPOSE: To report the experience of the school in implementing the 3 Rs replace, reduce and refine; showing time and assembling cost of the experimental models used in the teaching of Surgical Technique and Experimental Surgery. METHODS: Assembly time and costs of models: grafts and flaps performed in pork belly, model of intestinal anastomosis and jejunostomy done in Bahiana box and black box model for training videosurgery. RESULTS: Average time and cost estimate: ten minutes-pork belly, cost $ 6.00 per kilogram; two minutes-Bahiana box, cost $ 27.2; Black box-3.6 hours for manufacturing, cost $ 100.00. The repetition of each practice the cost is $ 3.20 for Bahiana box and at no cost to the black box. CONCLUSION: The experimental models presented are easily reproducible and of low cost. .

PURPOSE: The purpose of this study is to determine the educational suitability of the video-laryngoscope in teaching endotracheal intubation to students. METHODS: Medical students participated in a course on the use of a Macintosh direct laryngoscope and McGrath MAC videolaryngoscope for intubation. The course comprised a 1-hour lecture and 30 minutes of practice on a manikin. After the course, in each of the three simulated patient scenarios-normal airway, cervical spine fixation, and tongue edema-time to intubate, success rate, and chance of complications were measured. A questionnaire was administered before and after the course to determine the suitability of intubation by video-laryngoscope for a medical education course. Also, changes in the perception and stance on the video-laryngoscope were evaluated. RESULTS: Time to intubate decreased as attempts were repeated. The first-attempt success rate in the cervical spine fixation scenario was higher using the video-laryngoscope (p=0.028). Rates if tooth injury were lower in the cervical spine fixation (p=0.005) and tongue edema scenarios (p=0.021) using the video-laryngoscope. Based on the questionnaires, students responded positively with regard to their knowledge of the video-laryngoscope, its practical value, and its suitability for medical education (p<0.001). Also, the preference for the video-laryngoscope was greater (p=0.044). Students felt that repeated attempts and feedback on intubation were helpful. CONCLUSION: The students' evaluations and surveys showed positive results to intubation by video-laryngoscope. Thus, based on its suitability for medical education it is reasonable to consider learning intubation using the video-laryngoscope.

PURPOSE: To develop a new experimental model of lower cost for training in videosurgery. METHODS: This project was performed at the Nucleus of Experimental Surgery of the Bahiana School of Medicine and Public Health, based on previous models described in the literature and under the supervision of the full professor of Operative Technique and Experimental Surgery II. It was made a model cube-shaped, made of wood, with holes distributed in various locations, rubber stoppers for the holes and lined externally with carpet, and internally with laminate. RESULTS: The new experimental model is of low cost and reproduces quite faithfully several videosurgical procedures. CONCLUSION: Medical schools interested in the subject may adopt the new model for training in videosurgery without the need of high costs for making and using these models.
OBJETIVO: Desenvolver um novo modelo experimental de baixo custo para treinamento em videocirurgia MÉTODOS: Este projeto foi conduzido no Núcleo de Cirurgia Experimental da Escola Bahiana de Medicina e Saúde Pública, baseado em modelos prévios descritos na literatura e sob a supervisão do professor titular de Técnica Operatória e Cirurgia Experimental II. Foi feito um modelo em formato de cubo, de madeira, com furos distribuídos em vários locais, tampas de borracha para os orifícios e forrado externamente com carpete e internamente com laminado. RESULTADOS: O novo modelo experimental desenvolvido é de baixo custo e reproduz de forma bastante fiel diversos procedimentos videocirúrgicos. CONCLUSÃO: Faculdades médicas interessadas no tema poderão adotar o novo modelo para o treinamento em videocirurgia sem que sejam necessários gastos elevados para a confecção e o uso desses modelos.
