[Construction and application of virtual simulation teaching platform for in-hospital emergency nursing of craniofacial injury patients].

Purpose: To construct a virtual simulation teaching platform for in-hospital emergency nursing of craniofacial injury patients by virtual simulation technology, and to evaluate its application effect.

Methods: Through virtual reality, animation, human-computer interaction and other technologies, a 3D experiment scene based on high simulation virtual human was constructed to reproduce the virtual rescue scenes of craniofacial injury patients, such as emergency reception, first-aid cooperation, massive hemorrhage rescue cooperation, and tracheotomy cooperation in emergency rescue of sudden airway obstruction, and exercise modules and assessment modules were set. In the virtual simulation platform, the students used the holistic nursing theory and the PDCA cycle method to observe, evaluate and care for craniofacial injury patients. Preliminary evaluation of the platform was carried out in the training of 62 dental nurses.

Results: The virtual simulation platform could improve students' comprehensive first-aid ability for craniofacial injury patients. The item with the highest satisfaction rate for the virtual simulation platform was the consistency between the content of the virtual simulation platform and the theoretical course (the satisfaction rate was 91.9%), and the lowest satisfaction rate was the convenience of the virtual simulation platform operation and the page setting (the satisfaction rate was 80.6%). The evaluation module of the virtual simulation platform showed that the highest score of the comprehensive evaluation was 97, the lowest score was 56, and the average score was 80.2.

Conclusions: The virtual simulation teaching platform for in-hospital first aid of craniofacial injury patients can create an immersive learning mode, provide an intuitive rescue experience to the students, and improve their comprehensive first-aid ability.
