This study aims to develop an upper body manikin with a high-fidelity upper gastrointestinal tract and apply into the nasogastric tube training program for nursing students.

Background： Nursing trainees often fail to correctly prepare medical supplies and use stethoscopes for position assessment incorrectly when physicians perform nasogastric tube placement techniques. The traditional training model are expensive and difficult to access or maintain. It is easy to cause irreparable damage when repeated tearing and sticking of the elastic adhesive tape on the traditional model. Because of the high-priced the traditional model, it is impossible to use real milk, to simulate the nasogastric tube feeding. Inadequate clinical skills often raises patient safety concerns when assisting in changing nose pads and feeding. To enhance the nasogastric tube training for nursing students, the investigators used 3D-printed education model combined with clinical simulation-based training program. Study Design： This is a randomized controlled trial of medical education study. Methods： The investigators first designed our 3D upper body model using the 3D processing and analysis software. To create the basic outline of the 3D model, the investigators used a white-light handheld 3D scanner to scan a real human. To closely resemble the soft biological tissues of real human organs, an adequate material will be chosen in the study. The pre/post examination, student satisfaction, and direct observation of procedural skills will be used to evaluation the outcome of the study. Effect： The investigators expect the 3D-printed upper body manikin with a high-fidelity upper gastrointestinal tract model has potential in nasogastric tube training, particularly in helping trainees become familiar with the nasogastric tube care.
