Objective? To understand the psychological experience of nursing interns who underwent bedside rescue events. Methods? From September to December of 2018, 12 nursing interns who underwent bedside rescue events in Rescue Room of Emergency Department were interviewed and data was processed by Colaizzi 7-step analysis method. Results? Totally five themes were extracted: novelty and overwhelming, orderly rescue work caused the nursing interns to think about their own value, the sense of value due to professional identity, solid basic skills and reasonable teaching is the cornerstone of the rescue room internship, and the perception of sense of mission. Conclusions? Schools and hospitals should pay attention to the cultivation of soft skills of nursing interns, improve the familiarity of nursing interns with first-aid equipment, consolidate their basic skills, and establish a standardized first-aid process to improve the teaching work to foster first-aid awareness of nursing interns and promote nursing students to integrate into the rescue environment.
