Objective To explore the application effect of microlecture teaching approach based on UMU platform in the training of nutritional nursing for surgical nurses. Methods Surgical nurses were trained nutrition nursing in batches according to year training plan in surgical department, the 80 surgical nurses who were trained from February to March 2019 were selected as a control group, who were trained using the traditional classroom lecturing; another 80 surgical nurses who were trained in June 2019 were regarded as an intervention group, who were trained using the microlecture teaching approach based on UMU platform. The theoretical and operational examination results, the implementation of clinical standardization of enteral nutrition and the training satisfaction of the two groups were compared between the two groups. Results After the training, the theoretical and operational examination scores of the intervention group were significantly higher than those of the control group, the implementation rate (except for 3 identifications and flushing drainage tube 3 times) of enteral nutrition standardization for patients was significantly higher than that of the control group (P<0.05, P<0.01); and the training satisfaction of each indicators (except for accurate training key points and guiding clinical work) in the intervention group were significantly higher than those in the control group (P<0.05, P<0.01). Conclusion Application of the microlecture teaching approach based on UMU platform in nutritional nursing training for surgical nurses, can enhance the nurses′ nutrition knowledge and operational skill, then effectively improve nutrition nursing quality in surgical department.
