Development of an Anatomically Accurate 3D Simulation Model for Pediatric Central Line Placement

Background: ICU patients can require a central venous catheter (CVC) which medical trainees often place. Objective: The purpose of this study was to create a novel 3-dimensional (3D) printed model, based on actual patient anatomy from a deidentified computed tomography (CT) scan, with improved anatomy, tactile properties and realism beyond current task trainers for pediatric CVC simulation. Design/Methods: Bakken 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. Results: 15 faculty participated and 14 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 lines 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 the model's blood vessels be fully visible on ultrasound and that the model be firmer. Conclusion(s): Creating a 3D simulation model for pediatric CVC placement is possible. Next steps for this project include revision of the model to be firmer and with improved vessel appearance on ultrasound.
