Application research of virtual reality technology (VR) in pain management of dressing change after perianal abscess surgery
虚拟现实技术（VR）在肛周脓肿术后换药疼痛管理中的应用研究

摘要

目的 探究VR技术在肛周脓肿术后换药中对患者疼痛、生命体征、焦虑的影响，构建低成本易操作可复制的术后疼痛管理模式。方法 选取重庆市沙坪坝区人民医院胃肠肛肠外科2025年8月至2026年1月收治的74例肛周脓肿术后患者，采用非随机对照研究方法，将2025年8月-2026年1月肛周脓肿患者74例，按入院时间分为对照组（37例，2025年8月至10月）与实验组（37例，2025年11月至2026年1月）；对照组行常规换药疼痛干预，实验组加用VR SHINECON头戴设备，同步播放积极视频或游戏内容。结果 实验组NRS疼痛评分、收缩压、舒张压、心率、呼吸频率及SAS焦虑评分均低于对照组（P＜0.05）。结论 VR技术可有效缓解肛周脓肿术后患者换药疼痛，改善患者生命体征及焦虑状态，具有较高的推广价值。

Abstract

Objective To explore the impact of VR technology on patients' pain, vital signs, and anxiety during dressing changes after perianal abscess surgery, and to construct a low-cost, easy to operate, and replicable postoperative pain management model.
Methods A non-randomized controlled study was conducted on 74 postoperative patients with perianal abscess admitted to the Department of Gastroenterology and Colorectal Surgery at Shapingba District People's Hospital in Chongqing from August 2025 to January 2026. The patients were divided into a control group (37 cases, 2025.8-10) and an experimental group (37 cases, 2025.11-2026.1) according to their admission time; The control group received routine dressing change pain intervention, while the experimental group received VR SHINECON head mounted devices and simultaneously played positive videos or game content.
Results The NRS pain score, systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and SAS anxiety score in the experimental group were all lower than those in the control group (P<0.05).
Conclusion   VR technology can effectively alleviate dressing pain, improve vital signs and anxiety status in patients with perianal abscess after surgery, and has high promotion value.
