基于时机理论框架探讨重度烧伤患儿照护者在疾病不同阶段的照护体验，为构建分期干预方案及建立多元化支持体系提供依据。

采用质性研究方法，通过目的抽样法结合最大差异化抽样策略选取2024年1至12月就诊于空军军医大学西京医院烧伤与皮肤外科的18例重度烧伤患儿的照护者为研究对象，以时机理论为指导，于不同阶段进行面对面半结构式访谈并收集资料，运用内容分析法分析资料并提炼主题。

按烧伤分期提炼出3个主题包括9个亚主题。（1）休克期：自责与内疚、治疗需求迫切；（2）治疗期：生活重心转移、因知识匮乏而焦虑、经济负担沉重、照护任务繁重与渴望得到社会援助；（3）康复期：对患儿未来担忧、康复护理需求增加。

医护人员、家庭成员及社会团体应关注重度烧伤患儿照护者在患儿疾病各阶段的动态照护体验及需求变化，为其提供全程、细致的身心照护与专业指导。在提升烧伤患儿救治成功率的同时，需兼顾其照护者的需求，构建多方位支持体系以减轻其心理负担，从而更好地推动重度烧伤患儿的治疗与康复进程，最终提升患儿的生活质量。

Based on the framework of timing theory， this study explores the caregiving experiences of caregivers for children with severe burns at different disease stages， providing a basis for constructing staged intervention plans and establishing a diversified support system.

A qualitative research method was employed， using purposive sampling combined with maximum differentiation sampling strategy to select 18 caregivers of children with severe burns who were treated at Department of Burns and Cutaneous Surgery， Burn Center of PLA， Xijing Hospital, Air Force Medical Univercity from January 2024 to December 2024 as study subjects. Guided by the timing theory， face-to-face semi-structured interviews were conducted at different stages， and data were collected and analyzed using content analysis to extract themes.

Three themes were identified based on burn staging， comprising 9 sub-themes. (1) Shock stage： self-blame/guilt and urgent treatment needs； (2) Treatment stage： shift in life priorities， anxiety due to lack of knowledge， heavy financial burden， demanding caregiving tasks， and desire for social assistance； (3) Rehabilitation stage： increased concerns about the child's future and the need for rehabilitation care.

Healthcare providers， family members， and social organizations should pay attention to the dynamic caregiving experiences and changing needs of caregivers for children with severe burns at different disease stages， providing comprehensive， meticulous physical and psychological care and professional guidance. While improving the treatment success rate of pediatric burn patients， it is essential to address the needs of their caregivers by establishing a comprehensive support system to alleviate psychological burdens. This approach will better facilitate the treatment and rehabilitation process for severe burn patients， ultimately enhancing their quality of life.
