目的 探讨经历患者安全事件的ICU护士第二受害者的创伤复苏路径，为构建支持性干预策略提供参考。方法 采用扎根理论研究方法，对郑州市某三级甲等医院不良事件上报系统中近3年经历患者安全事件的23名ICU护士进行深度访谈。运用Strauss和Corbin扎根理论研究方法进行资料分析及模型构建。结果 经历患者安全事件的ICU护士创伤复苏路径包括事故响应期（权衡、应对行为）、应激期（压力源、心理体验、生理症状、行为体验）、调适期（支持需求、自我修复、职业认知、组织安全氛围）、回归期（消极生存、积极生长、影响持续时间）4个阶段，创伤复苏模型揭示了第二受害者成长的过程及机制。结论 ICU护士第二受害者创伤恢复过程具有相对阶段性，组织安全氛围、组织支持是护士从应激期向调适期转变的外在重要推动力，职业认知、自我修复力是催生回归成长的内在因素。护理管理者应结合创伤复苏路径给予相应的干预措施，以促进ICU护士第二受害者积极成长。

Objective To explore the trauma recovery path of ICU nurses who experience patient safety incidents as second victims，and to provide a reference for constructing supportive intervention strategies. Methods Using gounded theory research approach，in-depth interviews were conducted with 23 ICU nurses in a hospital of Zhengzhou City who have undergone patient safety events in the recent three years. Data analysis and model construction were conducted using Strauss and Corbin’s grounded theory. Results The trauma recovery path of ICU nurses who experienced patient safety incidents included four stages：accident response period（trade-offs，coping behaviors），stress period（stressors，psychological experiences，physical symptoms，behavioral experiences），adjustment period（support needs，self-repair，occupational cognition，organizational safety climate），reintegration period（negative survival，positive growth，impact duration）. The recovery model revealed the process and mechanisms of second victim growth. Conclusion The trauma recovery process of ICU nurses as second victims is relatively phased. Organizational safety climate and leadership support are critical external drivers for the transition from the stress phase to the adjustment phase，while professional cognition and self-healing ability are intrinsic factors that foster reintegration and growth. Nursing managers should provide corresponding interventions based on the trauma recovery path to promote the positive growth of ICU nurses as second victims.
