目的 探讨急危重症护理学实验课程思政的设计和应用效果。 方法 以某校2022级护理学专业378名本科生为研究对象，在急危重症护理学实验教学中，围绕急救医疗服务体系突发公共卫生事件设计课程思政教学。课前通过“案例—思政”双轨设计情景剧本；课中通过角色扮演逐步推进现场急救、途中转运、院内救治、重症监护，沉浸式体验协同救治过程中的政治认同和职业素养；课后通过志愿服务延伸社会。通过多维度考核评价体系综合分析教学成效，并调查课程思政育人满意度。 结果 考核结果显示，综合考核平均成绩（94.07±1.77）分，表明学生知识能力目标达成良好；96%的学生认为该教学方法新颖，且参与意愿强烈；90%的学生肯定了课程思政的育人效果。 结论 急危重症护理学实验教学中开展课程思政教学效果显著，实现了显性教育与隐性教育的统一，促进了专业知识与思政的协同发展，可为同类院校该课程思政改革提供参考。

Objective To explore the design and application effect of ideological and political education in the situational experiment teaching of Critical Care Nursing. Methods A total of 378 undergraduate students majoring in nursing from a certain university in 2022 were selected as the research subjects. In the scenario based experiential teaching of Critical Care Nursing，course ideological education was designed and implemented around the emergency medical service system and sudden public health emergencies. Before class，the scenario script was designed through the “case-ideological education dual-track” approach. During the class，through role-playing，the content was gradually advanced to include on-site first aid，transportation during the journey，in-hospital treatment，and intensive care. This enabled students to enhance their political identity and professional qualities through immersive experiences and collaborative treatment. After the class，the learned knowledge was extended to society through volunteer activities. The teaching effectiveness was comprehensively analyzed through a multi-dimensional assessment and evaluation system，and the satisfaction of course ideological and political education was also surveyed. Results The assessment results showed that the average score of the comprehensive assessment score of the students was （94.07±1.77） points，indicating that the students achieved good knowledge and ability goals；96% of the students believed that this teaching method was novel，and they had a strong willingness to participate；90% of the students affirmed the educational effect of course ideological and political education. Conclusion The implementation of ideological and political education in the scenario based experimental teaching of Critical Care Nursing has got remarkable results. It has realized the unity of explicit education and implicit education，and promoted the coordinated development of professional knowledge and ideological and political education. It can provide a reference for the reform of course ideological and political education in similar institutions.
