RESUMEN
Based on the latest results of international researches, combining with the experiences of our team in the simulation of acute dyspnea, Xiangya Hospital Central South University has summarized 7 characteristics, procedures and methods of debriefing, including that immediate feedback happens after simulation; feedback is provided by a trained instructor with clinical experience; feedback time is at least longer than the simulation time; various international methods of feedback can be used; the content of feedback is the learning objective; oral feedback is preferred; video can be used to review the details. The study aims to provide a theoretical basis for debriefing in domestic scenario stimulation teaching, and finally improve the effectiveness of the scenario stimulation teaching.
