In children, the pain and anxiety associated with acute burn dressing changes can be severe, with drug treatment alone frequently proving to be inadequate. Virtual reality (VR) systems have been successfully trialled in limited numbers of adult and paediatric burn patients. Augmented reality (AR) differs from VR in that it overlays virtual images onto the physical world, instead of creating a complete virtual world. This prospective randomised controlled trial investigated the use of AR as an adjunct to analgesia and sedation in children with acute burns. Forty-two children (30 male and 12 female), with an age range of 3-14 years (median age 9 years) and a total burn surface area ranging from 1 to 16% were randomised into a treatment (AR) arm and a control (basic cognitive therapy) arm after administration of analgesia and/or sedation. Pain scores, pulse rates (PR), respiratory rates (RR) and oxygen saturations (SaO2) were recorded pre-procedurally, at 10 min intervals and post-procedurally. Parents were also asked to grade their child's overall pain score for the dressing change. Mean pain scores were significantly lower (p=0.0060) in the AR group compared to the control group, as were parental pain assessment scores (p=0.015). Respiratory and pulse rates showed significant changes over time within groups, however, these were not significantly different between the two study groups. Oxygen saturation did not differ significantly over time or between the two study groups. This trial shows that augmented reality is a useful adjunct to pharmacological analgesia.
对于儿童而言，与急性烧伤换药相关的疼痛和焦虑可能非常严重，仅靠药物治疗往往效果不佳。虚拟现实（VR）系统已在数量有限的成人和儿科烧伤患者中成功进行了试验。增强现实（AR）与VR的不同之处在于，它将虚拟图像叠加在现实世界之上，而不是创建一个完整的虚拟世界。这项前瞻性随机对照试验研究了AR作为急性烧伤儿童镇痛和镇静辅助手段的应用。42名儿童（30名男性和12名女性），年龄在3至14岁之间（中位年龄9岁），烧伤总面积为1%至16%，在给予镇痛和/或镇静后被随机分为治疗（AR）组和对照（基本认知疗法）组。在操作前、每隔10分钟以及操作后记录疼痛评分、脉搏率（PR）、呼吸率（RR）和血氧饱和度（SaO2）。还要求家长对孩子换药时的总体疼痛评分进行分级。与对照组相比，AR组的平均疼痛评分显著更低（p = 0.0060），家长的疼痛评估评分也是如此（p = 0.015）。呼吸率和脉搏率在组内随时间有显著变化，然而，两组之间没有显著差异。血氧饱和度在两组之间以及随时间均无显著差异。该试验表明，增强现实是药物镇痛的一种有用辅助手段。
