Simulation-based education is commonly used in undergraduate training but has gained increased utilization in postgraduate education. Ambulance nursing programs struggle to provide suitable simulations, as ambulance care can involve any possible situation. Simulation-based education in ambulance nursing programs commonly includes basic assessment and treatment of various conditions. However, there seems to be a lack of knowledge regarding students' experience of simulating pediatric emergency care in an ambulance care setting. Thus, the aim of this study was to explore specialist nursing students' experiences of simulating pediatric emergency care in an ambulance care setting. A qualitative design was deployed, utilizing field notes, individual and group interviews to capture the students' experiences. The results show that students immerse themselves in the simulations when the environment and facilitators support this. The simulation can elicit both emotional and physical responses among the students. Students gain insights into their knowledge deficit regarding certain topics, such as pediatric emergency care, as well as the rules and regulations governing what they are allowed to do for a child's safety and well-being. During simulation, students understand the importance of using adequate communication and recognize that there might be several aspects influencing this. Finally, the students gain insight into their emotional and behavioral responses when encountering patients and relatives in situations that conflict with their own views. In conclusion, simulation-based education can be a useful pedagogical tool if barriers to immersion are reduced. It can provide students with insights into their emotional and behavioral responses when encountering unexpected events. If properly discussed in debriefing sessions, these matters lead to increased learning that students can carry with them into their future careers. However, more research is needed on the feasibility of this kind of simulation in the ambulance nurse education setting.
