Visual and acoustic virtual reality (VR) has been increasingly explored as a non-pharmacological tool for pain relief in clinical settings.
We aimed to evaluate the effectiveness of VR as a distraction technique in the management of acute pain during operative hysteroscopy in the outpatient setting.
A prospective, open-label, randomized control trial in a tertiary university-affiliated medical centre between April and August 2020. Overall, 82 women were randomly allocated to undergo operative hysteroscopy either with the use of VR (n = 44, study group) or with standard treatment (control group, n = 38). VR was applied throughout the procedure and no anaesthesia was given. The primary outcome measures included self-reported intraoperative pain. Other objectives included vital parameters as pulse rate (PR) and respiratory rate (RR) before and during the first 3 min of the procedure. Pain and anxiety outcomes were measured as numeric rating scores.
The baseline parameters were similar between groups. The mean duration for the procedure was 8.1 ± 3.2 vs. 7.3 ± 6.0 min for the study and the control groups (p = 0.23). There were no statistically significant differences between the reported pain scores during the procedure [median (interquartile range) 5.0 (3.0-7.2) vs. 5.0 (3.0-8.0), respectively; p = 0.67]. While neither intraoperative heart rate nor respiratory rate differed between groups [14.0 (13.0-16.0) vs. 14.0 (11.0-16.5); p = 0.77)], the increase of heart rate was found greater in the VR group [+7.0 (8.5) vs. +1.0 (12.2); p = 0.01].
VR was not effective in reducing pain during an outpatient operative hysteroscopy.
The use of a Virtual reality system was found ineffective in reducing pain during and after an office operative hysteroscopy without anaesthesia, in a thorough examination of both continuous physiological parameters and women's self-reported measures.
视觉和声学虚拟现实 (VR) 已作为一种非药物手段，在临床环境中越来越多地被用于缓解疼痛。
本研究旨在评估 VR 作为一种分散注意力的技术，在门诊手术性宫腔镜检查中管理急性疼痛的效果。
这是一项在 2020 年 4 月至 8 月期间在一家三级大学附属医院进行的前瞻性、开放标签、随机对照试验。总共 82 名女性被随机分配接受手术性宫腔镜检查，一组使用 VR（n=44，研究组），另一组使用标准治疗（对照组，n=38）。VR 在整个过程中使用，且不给予麻醉。主要结局指标包括术中自我报告的疼痛。其他目标包括手术前和手术开始后 3 分钟内的脉搏率 (PR) 和呼吸率 (RR) 等生命参数。疼痛和焦虑的结果以数字评分量表测量。
两组的基线参数相似。手术时间的平均时长为 8.1±3.2 分钟与 7.3±6.0 分钟（研究组与对照组，p=0.23）。手术过程中的报告疼痛评分无统计学差异[中位数（四分位间距）分别为 5.0（3.0-7.2）和 5.0（3.0-8.0）；p=0.67]。两组术中的心率和呼吸率也无差异[14.0（13.0-16.0）与 14.0（11.0-16.5）；p=0.77)]，但研究组的心率增加幅度更大[+7.0（8.5）与 +1.0（12.2）；p=0.01]。
VR 在门诊手术性宫腔镜检查中无法有效减轻疼痛。
在一项没有麻醉的门诊手术性宫腔镜检查中，全面检查连续生理参数和女性自我报告的措施后，发现使用虚拟现实系统无法减轻疼痛。
