Educational project: low cost porcine model for venous cutdown training / Projeto de ensino: modelo porcino de baixo custo para treinamento de dissecção venosa

ABSTRACT Objective: to describe and evaluate the acceptance of a porcine experimental model in venous cutdown on a medical education project in Southwest of Brazil. Method: a porcine experimental model was developed for training in venous cutdown as a teaching project. Medical students and resident physicians received theoretical training in this surgical technique and then practiced it on the model. After performing the procedure, participants completed a questionnaire on the proposed model. This study presents the model and analyzes the questionnaire responses. Results: the study included 69 participants who used and evaluated the model. The overall quality of the porcine model was estimated at 9.16 while the anatomical correlation between this and human anatomy received a mean score of 8.07. The model was approved and considered useful in the teaching of venous cutdown. Conclusions: venous dissection training in porcine model showed good acceptance among medical students and residents of this institution. This simple and easy to assemble model has potential as an educational tool for its resemblance to the human anatomy and low cost.

RESUMO Objetivo: descrever e avaliar a aceitação de um modelo experimental porcino no aprendizado de dissecção venosa em projeto de educação médica no sudoeste do Brasil. Método: um modelo experimental porcino foi desenvolvido para treinamento em dissecção venosa como projeto de ensino. Estudantes de medicina e médicos residentes receberam treinamento teórico sobre esta técnica cirúrgica e em seguida a praticaram no modelo. Após realizar o procedimento, os participantes preencheram um questionário sobre o modelo proposto. Este estudo apresenta o modelo e analisa as respostas ao questionário. Resultados: o estudo contou com 69 participantes que utilizaram e avaliaram o modelo. A qualidade geral do modelo porcino foi estimada em 9,16 enquanto a correlação anatômica entre este e a anatomia humana recebeu o escore médio de 8,07. O modelo foi aprovado e considerado útil no ensino da dissecção venosa. Conclusão: o treinamento de dissecção venosa em modelo porcino apresentou boa aceitação entre estudantes e residentes de medicina desta Instituição. Este modelo simples e de fácil confecção, tem potencial como instrumento de aprendizado por sua semelhança com a anatomia humana, e baixo custo.

Surgical model pig ex vivo for venous dissection teaching in medical schools

Abstract Purpose: To investigate a method for development of surgical skills in medical students simulating venous dissection in surgical ex vivo pig model. Methods: Prospective, analytical, experimental, controlled study with four stages: selection, theoretical teaching, training and assessment. Sample of 312 students was divided into two groups: Group A - 2nd semester students; Group B - students of 8th semester. The groups were divided into five groups of 12 students, trained two hours per week in the semester. They set up four models to three students in each skill station assisted by a monitor. Teaching protocol emergency procedures training were applied to venous dissection, test goal-discursive and OSATS scale. Results: The pre-test confirmed that the methodology has not been previously applied to the students. The averages obtained in the theoretical evaluation reached satisfactory parameters in both groups. The results of applying OSATS scale showed the best performance in group A compared to group B, however, both groups had satisfactory medium. Conclusion: The method was enough to raise a satisfactory level of skill both groups in venous dissection running on surgical swine ex vivo models.
