Impact of Via CT-based 3D Printing Technology on Success Rate in Endotracheal Intubation in Students

Impact of Via CT-based 3D Models and 3D Printing Technology on Success Rate in Endotracheal Intubation in Undergraduate Medical Students-A Prospective Single-Center Study

The objective of this project is to develop a tracheal intubation teaching curriculum covering both normal and difficult airways using CT three-dimensional imaging and 3D printing technologies, enabling trainees to intuitively learn anatomical knowledge, operational skills, and special handling techniques, and to evaluate the learning outcomes. The research content includes the establishment of airway models and the training of students. Trainees in Group A will be trained using the tracheal intubation curriculum independently developed in this project, while trainees in Group B will be trained using traditional teaching methods, where instructors explain the course content via PowerPoint, elaborate on key and difficult points, answer student questions, and provide a summary. The teaching content for both groups is identical. After the teaching session, the teaching effectiveness will be evaluated using the second part of the teaching assessment methods.
