虚拟现实技术在ICU患者早期活动中的应用研究

目的 分析虚拟现实技术在ICU患者早期活动中的应用效果。方法 2021年11月—2022年1月，采用便利抽样法，选取上海市某三级甲等医院ICU收治的76例患者作为研究对象，根据随机数字表法将患者分为试验组和对照组。试验组在常规护理的基础上通过虚拟现实技术进行早期活动；对照组进行常规早期活动，比较两组医学研究委员会评分、握力和每次运动时长、ICU住院时间、风险事件的差异。结果 68例患者完成了该研究，试验组37例，对照组31例。试验组ICU获得性衰弱发生率（13.50%）低于对照组（35.50%），试验组医学研究委员会评分为（57.08±3.24）分，高于对照组（55.74±4.28）分；试验组每次运动时长为（19.78±4.90） min，高于对照组（14.94±6.78） min，试验组ICU住院时长为（4.65±2.82） d，低于对照组（6.90±2.40） d，差异均有统计学意义（P<0.05）；但试验组握力与对照组相比，差异无统计学意义（P=0.393）。结论 虚拟现实技术有助于ICU患者早期活动，预防ICU获得性衰弱，缩短ICU住院时长，促进患者康复。

Application of virtual reality technology in early activities of ICU patients

Objective To investigate the application effects of virtual reality technology in early activities of critically ill patients. Methods From November 2021 to January 2022，76 patients in the surgical intensive care unit of a tertiary A hospital in Shanghai were selected as the research subjects and divided into an experimental group and a control group according to the random number table method. The control group was given routine early activities，and the experimental group was given early activity intervention through virtual reality technology. The Medical Research Council score，grip strength，the duration of exercise，the length of ICU stay and risk events were observed and compared between the 2 groups. Results 68 ICU patients completed the study. The incidence of ICU-acquired weakness in the experimental group（13.50%） was lower than that in the control group（35.50%），and the muscle strength score of（57.08±3.24） by Medical Research Council in the experimental group was higher than that of（55.74±4.28） in the control group. The duration of exercise in the experimental group was （19.78±4.90） minutes，which was higher than that of （14.94±6.78） minutes in the control group. The length of ICU stay in the experimental group was（4.65±2.82） days，which was lower than that of（6.90±2.40） days in the control group，and the differences were statistically significant（P<0.05）. There was no significant difference in grip strength between the experimental group and the control group（P=0.393）. Conclusion Virtual reality technology can help ICU patients with their early activities，improve their muscle strength，prevent ICU-acquired weakness，reduce length of ICU stay， and promote rehabilitation of patients.
