Abstract: Objective T o evaluate the application of mind mapping combined with PDCA cycle teaching in emergency nursing practice, so as to provide basis for improving the quality of nursing practice teaching. Methods A total of 120 undergraduate nursing students working in the emergency department of the Second Affiliated Hospital of Dalian Medical University from July 2016 to April 2018 were selected as the research subjects, and they were randomly divided into experimental group and control group, with 60 students in each group. The experimental group adopted the mind map combined with PDCA cycle teaching to find the problems in emergency nursing practice through PDCA, and solved the problems with the clear context of mind map. The students in the control group adopted conventional clinical teaching. The satisfaction, training outcome and improvement of clinical reasoning of the two groups of students were compared. Results After continuous quality improvement, the experimental group students' satisfaction with teaching methods was 100.0%(60/60), the satisfaction with teachers' attitude was 93.3%(56/60), the control group students' satisfaction with teaching methods was 80.0%(48/60), the satisfaction with teachers' attitude was 76.7%(46/60), the difference was statistically significant (χ²=13.333, 6.536, all P<0.05). The excellent rate of theoretical achievement and the excellent rate of skill operation examination in the experimental group are higher than those in the control group, and the differences are statistically significant (χ²=6.988,4.415, all P<0.05); The total score of clinical thinking ability and scores of all dimensions of experimental group students are higher than those of control group students (t=-2.975, -4.573, -7.371, -5.702, all P<0.05). Conclusions The application of mind mapping combined with PDCA cycle teaching in emergency nursing practice can effectively improve the satisfaction of trainee, and improve the excellent rate of trainees' theoretical knowledge and operation skills, and improve their clinical reasoning.
