Influence Of Calming Music In A VR Environment On Preoperative Anxiety In Patients With Eye Diseases

OBJECTIVES: 1.Simulate the operating room scene of the ophthalmology with VR,and explore the effect of this scene on the anxiety level of patients with preoperative eye disease;2.The effect of calming music listening on the level of anxiety in the VR operating room scene;3.Integrate theory with practice,The research results in the theoretical stage lay the theoretical foundation for the development of "VR sound vision" products;4.Combined with the narrative design concept to design "VR sound vision" for patients with eye diseases to reduce anxiety before surgery.METHODS: A clinical controlled trial was conducted to select n=65 preoperative patients in the ophthalmology day ward of Renji Hospital Affiliated to Shanghai JiaoTong University.The subjects were randomly divided into Experimental Group(VR simulated operating room environment,with music)n=33 and Control Group(VR simulated operating room environment,no music)n=32,collected test galvanic skin response SC/GSR value data;heart rate HR(BVP)data;heart rate variability RMSSD,SDNN data;STAI anxiety scale data;VREQ preoperative virtual reality scale data;demographic analysis will be carried out by sample,statistical analysis will be performed using Excel software,T test analysis,F analysis,M value and SD value analysis will be performed.RESULTS: 1.Baseline data: There was no significant difference in the baseline between the Experimental Group and the Control Group(P>0.05).The data were comparable.2.Before and after the experiment of Control Group,the SC/GSR data、the heart rate HR(BVP)data and the STAI anxiety scale T-AI data were different but not significant(0.01<P<0.05).The difference was located in the increase of anxiety;the STAI anxiety scale S-AI data showed significant difference(P<0.01),the difference was located in the significant increase of anxiety;heart rate variability RMSSD,SDNN data were not statistically different(P>0.05),the degree of anxiety was unchanged;3,Before and after the experiment of Experimental Group,the data of the SC/GSR data and the STAI anxiety scale of the experimental group were significantly different(P<0.01),and the difference was located at the significant reduction of anxiety;heart rate HR(BVP)data,heart rate variability RMSSD,SDNN There was no statistical difference in the data(P>0.05),and the degree of anxiety did not change.CONCLUSIONS: 1.The SC/GSR,HR(BVP),S-AI,and T-AI indicators of ophthalmic patients will increase in the VR simulation operating room environment;2.The SC/GSR,S-AI,and T-AI indicators of ophthalmic patients will be reduced when the VR simulated operating room environment is supplemented with calming music.3.Heart rate variability RMSSD and SDNN do not affect the anxiety value of ophthalmic patients;4.Calming music still plays a role in reducing the anxiety value of ophthalmic patients in heart rate HR(BVP).5.The role of SC/GSR,HR(BVP)in the experimental group,the T-AI fitting curve in the control group is well fitted.6.The VR simulation operating room scenario has less stress than the real operating room scene.7.Eye disease patients in the VR environment with the simulated operating room,over 50 years old,primary school and below,married,female,office clerk anxiety increased the most,18-50 years old undergraduate and above,unmarried,Males and freelancers have the least increase in anxiety.8.Eye disease patients in the VR environment with the simulated operating room,while listening to calming music,18-50 years old primary school and below,unmarried men,freelancers have the greatest decrease in anxiety,over the age of 50,junior college Married,female,office clerk relieve anxiety minimum extent.DESIGN PRACTICE: Calming music in VR environment can reduce preoperative anxiety in ophthalmic patients.In the design process,1.Use the results of preoperative anxiety theory research of eye patients combined with narrative design concept to design "VR sound vision";2.User survey and research the user environment,user groups and user needs;3.Design and planning,“VR sound vision” design concept and design planning,technical implementation,interactive interface design;4.Testing and evaluation,for stakeholders,understand the needs of eye patients and health care providers,and make reflective design evaluations.
