Abstract

Intensive care unit patients can require a central venous catheter (CVC) which medical trainees often place. The purpose of this study was to create a novel three-dimensional (3D) printed model, based on actual patient anatomy from a de-identified computed tomography (CT) scan, with improved anatomy, tactile properties, and realism beyond current task trainers for pediatric CVC placement simulation. Bakken Center researchers converted CT DICOM slices into a 3D model using multiple computer programs and multiple 3D printers. Faculty of various subspecialties at our institution attempted to place a CVC line into the model and then evaluated the model in 5 categories using an anonymous REDCap survey. Fifteen faculty participated and fourteen completed their survey. Feedback, based on a 0–10 scale with 10 being highest, was as follows: the model's size scored an average of 8.4, the model's tactile properties scored a 6.1, the model's anatomy received a 7.1, the model's perceived usefulness for practicing central line placement received a 7.6, and the model received a 7.6 in regard to whether it should be utilized in procedural training curriculums. Additional comments were collected in the survey and participants requested that the model's blood vessels be fully visible on ultrasound and that the model be firmer. In conclusion, creating a 3D simulation model for pediatric CVC placement is possible.
