Summary:ABSTRACT Introduction: simulation based teaching is a powerful tool in medical education, allowing hands on practice under a controlled environment and with repeated maneuvers. Central venous access venipuncture is one of the most frequent procedures carried out in the hospital setting, due to its various clinical indications and, when performed with the help of ultrasonography, the risk of adverse events is minimized. Aim: to develop, to describe and to test a porcine model that simulates the central venous access puncture aided by ultrasonography. Method: a low cost porcine model was developed to train medical students and residents on central venous access guided by ultrasonography. Both students and medical residents underwent a theoretical training regarding the model, followed by a hands-on training session. Afterwards, the participants assessed the model by answering a questionnaire. Results: there were 51 participants. The average score regarding the similarity between the model and the human anatomy was 9.15. When the characteristics were separately assessed, the mean scores regarding the similarity of the vessels, anatomic disposition and ultrasonographic characteristics as well as the venipuncture were, respectively, 9.27; 9.31; 9.54 and 8.86. Conclusion: The model was approved and considered appropriate for the training of central venous venipuncture by all the participants. Furthermore, it is a low cost, simple and reproducible model, that presents high similarity with the human anatomy. Therefore, it may be used as an aid to train people on ultrasonography guided central venous access. RESUMO Introdução: o ensino baseado em simulação é poderosa ferramenta para o aprendizado na educação médica, permitindo a prática de procedimentos em ambientes controlados e por repetidas vezes. A realização de acesso venoso central é um dos procedimentos médicos mais realizados em ambiente hospitalar, tendo várias indicações e, quando realizada com o auxilio da ultrassonografia, os riscos das complicações do procedimento são minimizados. Objetivo: desenvolver, descrever e aplicar um modelo porcino para simulação de acesso venoso central guiado por ultrassonografia. Métodos: modelo porcino de baixo custo foi desenvolvido para treinamento de acesso venoso central guiado por ultrassonografia. Estudantes de medicina e médicos residentes receberam treinamento teórico em relação ao procedimento, seguido de treinamento prático no modelo. Posteriormente, os participa
