Objective: To explore the effect of staged situational simulation education on delivery outcome, role adaptability of mothers and breastfeeding in primipara. Methods: A total of 244 primiparas delivered in our hospital from June 2018 to May 2019 were included as the study objects. The patients were divided into two groups according to their wishes, including 122 cases in the control group and 122 cases in the study group. The control group received regular collective health education, and the research group carried out staged situational simulation education on this basis. The outcome of delivery, the adaptability to the role of the mother before and 3 months after the intervention, and the feeding situation of the two groups were compared. Results: The incidence of natural delivery in the study group was higher than that in the control group (P<0.01), and the cesarean delivery rate was lower than that in the control group (P<0.01). After 3 months of intervention, the scores of care behavior, role identity and parent-child attachment in the study group were higher than those in the control group (P<0.01). The breastfeeding rate of the study group was higher than that of the control group (P<0.01), and the artificial feeding and mixed feeding rate were lower than those in control group (P<0.01). Conclusion: Staged situational simulation education can effectively improve the delivery outcome in primipara, improve the role adaptability of mother, and ensure the quality of breastfeeding, which is worthy of clinical promotion.
