Abstract: Objective To conduct a scoping review to identify the specific intervention,results and limitations of virtual reality（VR）technology in adult ICU patients,so as to provide the guidance for future research and clinical application. Methods A literature search was performed in the CNKI,Wanfang database,VIP,CBM,Cochrane Library,PubMed,Embase,Web of Science,CINAHL,Scopus,Proquest and IEEE Xplore to identify relevant studies. The retrial limit was from database establishment to March 11,2023. The studies were screened and data was extrated independently by two researchers. Results Totally 23 studies were included,including nine randomized controlled trials,two quasi-experimental studies and two observational studies. Virtual reality（VR）technology provided relaxation and rehabilitation intervention for adult ICU patients. The results showed that VR interventions had positive effects on the motor function rehabilitation of patients,and had a potential effect on the prevention of delirium. However,due to the limitations of sample size,intervention periodicity,environment,whether it can improve cognition,psychology,sleep and pain was still controversial. No serious adverse events were reported and the acceptability of VR technology intervention in patients was good. Conclusion Virtual reality technology is feasible and has a positive effect on adult ICU patients. Future research should combine the advantages of “Internet plus nursing service”,take patients as the center,combine technological innovation and humanistic nursing,to formulate standardized evaluation standards and explore more comprehensive and personalized intervention strategies.
