Abstract:

Objective To explore the effect of virtual reality（VR） intervention on improving preoperative anxiety of adult patients. Methods We searched PubMed,Embase,Web of Science,Cochrane Library,CNKI,Wanfang Data from the inception to February,2022. There were 2 researchers who independently screened the literature,extracted information. RevMan 5.4 was used to analyze the data after the quality of literature was assessed. Results 12 randomized controlled trials were finally included,with a total of 1247 patients. The results of meta-analysis showed that the preoperative exposure based on VR technology[SMD=-0.45,95%CI（-0.61,-0.29）,P<0.01] and distraction[SMD=-0.24,95%CI（-0.44,-0.04）,P<0.05] could effectively reduce the preoperative anxiety of adult patients. Conclusion The preoperative VR intervention can effectively alleviate the preoperative stress of adult surgical patients by VR distraction or VR exposure.

摘要：

目的 探讨虚拟现实（virtual reality,VR）技术对改善成人患者术前焦虑的效果。方法 计算机检索PubMed、Embase、Cochrane Library、Web of Science、中国知网、维普数据库和万方数据库,搜集关于虚拟现实技术干预对改善成人患者术前焦虑效果的研究,检索时限均为从建库至2022年2月。由2名评价员独立筛选文献、提取资料和评价纳入研究的质量,采用RevMan 5.4软件进行Meta分析。 结果 最终纳入12项随机对照试验研究,包括 1 247例患者。Meta分析结果显示,术前基于虚拟现实暴露[SMD=-0.45,95%CI（-0.61,-0.29）, P<0.01]和基于虚拟现实分散注意力干预[SMD=-0.24,95%CI（-0.44,-0.04）,P<0.05]均能够有效缓解成人患者术前焦虑。 结论 术前基于虚拟现实暴露或分散注意力干预可有效缓解成人患者术前焦虑。
