Construcción de biomodelo para cateterización intravenosa en pacientes caninos

Abstract

Peripheral canalization is one of the most practiced techniques by veterinary professionals. They are techniques that consume time, require practice, and generate pain. Consequently, the creation of a 3D-printed model of the canine forelimb will facilitate adequate intravenous cannulation since it guarantees the improvement of the quality of work, thus reducing stress in our patients. 3D printing is a manufacturing process in which a three-dimensional object is created from a digital model using successive layers of material. Unlike traditional manufacturing methods, this adds material layer by layer to build the desired object. One of the critical processes in 3D printing is obtaining a digital model, which can be achieved through medical scanning techniques, such as CT or MRI, which capture the patient's anatomy. These images are converted into 3D digital models, which are then used to generate the design file for the printer. The use of models in intravenous catheterization training provides several advantages. Students have the opportunity to become familiar with canine vascular anatomy and structure in a safe and risk-free manner. They can practice identifying relevant veins, assessing emerging tissues’ resistance and response , and refining catheter insertion and advancement techniques. Furthermore, models allow the repetition of procedures, which facilitates gradual learning and error correction.
