目的 对虚拟现实(virtual reality,VR)系统在重症患者中应用的相关研究进行范围审查，探讨其可接受性、耐受性和潜在有效性。方法 根据范围综述研究方法，检索Embase、PubMed、Web of Science、Cochrane、中国知网、万方和维普等数据库，时限为建库至2022年12月31日；总结系统内容、干预方法、应用效果及局限性等。结果 共纳入20篇文献。主要探讨VR系统对重症患者睡眠、心理、疼痛、认知和早期活动等的影响；单次干预时长约5~30 min；患者对VR系统的接受度较高且满意度良好，不良反应轻微、可控；但临床实施方法不够完善，缺乏较为客观的特异性评估方式，且系统内容偏商业化，其专业性和针对性不强。结论 VR系统应用于重症患者中是可行的，且具有一定效果；未来研究应注重基于循证探索VR最佳干预策略，根据患者病情制定个体化干预方案，考虑跨学科合作定制适合重症患者的系统内容，并分析成本效益，以进一步在临床上推广应用。

Objective Through reviewing the researches,to study the acceptability,tolerability,and potential effectiveness of the application of virtual reality(VR) systems in critically ill patients.Methods Based on the methodology of the scope review,the literature databases,including Embase,PubMed,Web of Science,Cochrane,CNKI,Wanfang Data,and VIP,were searched with the retrieving time between the inception and December 31,2022.The system contents,intervention methods,application effects,and limitations were summarized.Results A total of 20 articles were included,which mainly discussed the influence of VR system on sleep,psychology,pain,cognition,and early activity in severe cases.The single intervention lasted approximately 5-30 min.The patients generally had high acceptance and satisfaction on VR intervention,with mild and controllable adverse reactions,but the clinical application need to improved,such as lacking objective and specific assessment method,over commercialized contents,less professional and targeted intervention.Conclusions VR system is feasible in the intervention of critical ill patients,and has a certain effect.The future research should focus on the evidence-based exploration of VR intervention strategy,providing individualized interventions according to patients’ conditions,developing suitable contents for critical ill patients based on interdisciplinary cooperation,and considering cost-benefit,so as to promote its application in clinical practice.
