针对癌症患儿外周静脉插管疼痛和焦虑的虚拟现实干预
Background 研究背景
Peripheral intravenous cannulation (PIC) is commonly performed in cancer treatment and causes pain and anxiety to children with cancer.
外周静脉插管(PIC)会引起癌症患儿的疼痛和焦虑。
Objective 研究目的
The aim of this study was to determine whether virtual reality distraction intervention can alleviate pain and anxiety and reduce length of procedure among pediatric cancer patients undergoing PIC.
本研究目的是探索虚拟现实分心干预（virtual reality distraction intervention）对减轻接受外周静脉插管癌症患儿的疼痛和焦虑和缩短手术时间的效果。
Methods 研究方法
One hundred eight pediatric cancer patients aged 6 to 17 years were recruited from a regional public hospital in Hong Kong to participate in this randomized controlled trial. The intervention group received virtual reality distraction intervention, and the control group received standard care. The primary outcome was child-reported pain. Secondary outcomes included child-reported anxiety, pulse rate, and length of procedure. Outcome measurements were conducted at 5 minutes before, during, and immediately after the procedure.
（1）随机对照试验设计；共从香港一公立医院招募108名6-17岁的癌症患儿。（2）干预组采用虚拟现实分心干预，对照组采用标准护理干预；其中主要结局指标是：患儿疼痛；次要结局指标为：儿童报告的焦虑、脉搏率和手术时间。（3）结果测量分别在手术前5分钟、术中5分钟和术后5分钟进行。
Results 研究结果
Pediatric cancer patients in the intervention group demonstrated a significantly greater reduction in pain (estimated mean difference = −1.69, P = .007) and anxiety levels (estimated mean difference = −3.50, P < .001) compared with the control group. The mean duration (in minutes) for the PIC procedure was significantly shorter among participants receiving virtual reality intervention compared with the control counterparts (estimated mean difference = −0.75, P = .017). However, no significant difference was observed in pulse rate during and after the procedure between groups.
（1）与对照组相比，干预组癌症患儿在疼痛和焦虑水平差异具有统计学意义；接受虚拟现实分心干预患儿的手术时间明显缩短。（2）两组患者在手术期间和术后的脉搏率无显著差异。
Conclusions 研究结论
Findings indicate that virtual reality is safe and effective to alleviate pain and anxiety among pediatric cancer patients undergoing PIC procedure.
研究结果表明，虚拟现实分心干预可有效缓解行PIC手术癌症患儿的疼痛和焦虑。
Implications for Practice 对临床实践的意义
Virtual reality can be considered as an adjunctive treatment to manage pain and anxiety in pediatric cancer patients before and during PIC procedure.
虚拟现实技术可作为一种辅助治疗手段，用于控制癌症患儿在PIC手术前后的疼痛和焦虑。
