AMATO, Alexandre Campos Moraes et al. Gelatin model for training ultrasound-guided puncture. J. vasc. bras. [online]. 2015, vol.14, n.3, pp.200-204.  Epub Sep 15, 2015. ISSN 1677-5449.


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.


To demonstrate creation and application of a gelatin model for training ultrasound-guided puncture.


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.


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.


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.

Keywords : training; interventional ultrasonography; ultrasonography.
