Methods: taking the children in the pediatric nursing center of the hospital as the research object, in order to ensure the authenticity and feasibility of the research results, 88 children were selected as the research object according to the research needs. In addition to meeting the requirements of the inclusion criteria, these children met the requirements of the hospitalization scope from June 2018 to June 2019. In order to highlight the application effect of safety management methods, the subjects of this study were divided into two groups, namely the observation group and the control group. The patients in these two groups were managed with safety management measures and conventional management methods respectively. Under the condition of ensuring that other conditions remain unchanged, the incidence of adverse events and nursing satisfaction of the two groups were compared. By analyzing these two indicators, the application effects of safety management measures and conventional management methods in pediatric nursing management were compared. Results: on the premise that the patients in the observation group used safety management measures and the patients in the control group used routine management measures, the patients in the observation group and the children in the control group were 4.6% and 22.7% respectively, and the satisfaction of their families with nursing work was 95.5% in the observation group and 84.1% in the control group, respectively, with no statistical significance (P < 0.05). Conclusion: compared with conventional management methods, the application effect of safety management method in pediatric nursing management is better. Therefore, this method is worthy of comprehensive promotion and application in clinic.展开更多
