Resumo

A ultrassonografia Doppler deixou de ter seu uso apenas como método diagnóstico e vem galgando espaço nos procedimentos terapêuticos. Com maior aplicabilidade e uso de cateteres venosos centrais e procedimentos guiados por ultrassom, há preocupação com a melhora da eficácia e segurança durante o procedimento, assim como com a diminuição das potenciais complicações. Para isso, o treinamento da técnica em modelos (phantoms) é desejável. Os modelos industrializados para treinamento em acesso vascular guiado por ultrassom são caros e não reproduzem adequadamente a ecotextura e a densidade dos tecidos humanos. Na tentativa de treinar e aprimorar os profissionais para o uso do ultrassom em procedimentos de acessos vasculares, desenvolveu-se um modelo animal de baixo custo, fácil confecção e excelente aplicabilidade.

Abstract

Duplex ultrasonography has not been used only as a noninvasive diagnostic method. Recently it has been applied for therapeutic procedures. Due to the increasing use and applicability of central venous catheters and eco-guided vascular procedures, there are concerns about improving results regarding accuracy and safety, reducing complication rates during those procedures. It would be desirable that training was accomplished using phantoms before actual procedures in human subjects. Industrialized phantoms are expensive and they do not reproduce human's ecographic density and texture. In order to train and improve ultrasound guided vascular access, we have developed a cheap animal tissue model, which is of easy preparation and applicability.
