The purpose of this study was to ascertain the feasibility and potential effect of a low-cost VR system (eMagin Z800 3DVisor), used in conjunction with pharmacological analgesia, on reducing pain and anxiety in adult burn patients undergoing physiotherapy treatment, compared to pharmacologic analgesia alone at a South African hospital.
Single-blind, within-subject study design.
Pain and anxiety outcome measures were measured by a blinded assessor using the Numeric Pain Rating Scale and Burn Specific Pain and Anxiety Scale. Box-and-whisker plot method, Chi-square tests as well as the Student's paired t-test were used to analyze data.
Eleven eligible adult burn patients consented to participate in this study (3 female, 8 male; median age 33 years: range 23-54 years). A marginal (p=0.06) to insignificant (p=0.13) difference between the two sessions (analgesia with VR and analgesia without VR) in reducing pain was found. No significant difference (p=0.58) was found between the two sessions (analgesia with VR and analgesia without VR) for anxiety.
There seems to be a trend that the low-cost VR system, when added to routine pharmacological analgesics, is a safe technique and could be of considerable benefit if implemented into the pain management regime of burn units at a South African hospital.
本研究旨在确定一种低成本 VR 系统（eMagin Z800 3DVisor）与药物镇痛联合使用，在南非医院与单纯药物镇痛相比，是否能降低接受物理治疗的成人烧伤患者的疼痛和焦虑，并评估其可行性和潜在效果。
单盲、自身对照研究设计。
疼痛和焦虑的评估由盲法评估者使用数字疼痛评分量表和烧伤专用疼痛和焦虑量表进行。使用箱线图、卡方检验和学生配对 t 检验分析数据。
11 名符合条件的成年烧伤患者同意参与本研究（3 名女性，8 名男性；中位年龄 33 岁：范围 23-54 岁）。在减轻疼痛方面，两种治疗方案（使用 VR 镇痛和不使用 VR 镇痛）之间存在边际（p=0.06）到不显著（p=0.13）的差异。两种治疗方案（使用 VR 镇痛和不使用 VR 镇痛）在焦虑方面无显著差异（p=0.58）。
低成本 VR 系统在常规药物镇痛的基础上联合应用，似乎是一种安全的技术，如果在南非医院的烧伤病房疼痛管理方案中实施，可能会带来显著的益处。
