Venipuncture is one of the most frequent and frightening medical procedures for children. This randomized clinical trial aimed to evaluate whether pre-procedural immersive virtual reality (VR) education could decrease pain and anxiety during venipuncture procedure of children.
Sixty children scheduled for venipuncture at the phlebotomy unit were randomized into either the control or VR group. Before the procedure, children of the control group received conventional simple verbal instructions, whereas those of the VR group experienced a 4-min VR education regarding venipuncture. The primary outcome was the pain and anxiety of pediatric patients assessed with the children's hospital of eastern ontario pain scale. Secondary outcomes were parental satisfaction, venipuncture time, repeated procedure and procedural difficulty rated by phlebotomists.
The pain and anxiety score during the procedure was significantly lower in the VR group than in the control group (median [IQR], 6.0 [5.0-7.0] vs. 8.0 [6.0-9.8], = 0.001). Parental satisfaction about the procedural process were higher in the VR group than in the control group ( = 0.029), and the degree of procedural difficulty was lower in the VR group, compared to the control group ( = 0.026).
The preprocedural VR education significantly reduced pain and anxiety of children and decreased the procedural difficulty of phlebotomists during venipuncture procedure.

静脉穿刺是儿童最常见且令人恐惧的医疗操作之一。这项随机临床试验旨在评估术前沉浸式虚拟现实（VR）教育是否能减轻儿童静脉穿刺过程中的疼痛和焦虑。
60名计划在采血室进行静脉穿刺的儿童被随机分为对照组或VR组。在操作前，对照组儿童接受常规的简单口头指导，而VR组儿童接受4分钟的静脉穿刺VR教育。主要结局是用安大略东部儿童医院疼痛量表评估的儿科患者的疼痛和焦虑。次要结局是家长满意度、静脉穿刺时间、重复操作以及采血人员评定的操作难度。
VR组操作过程中的疼痛和焦虑评分显著低于对照组（中位数[四分位间距]，6.0[5.0 - 7.0]对8.0[6.0 - 9.8]，P = 0.001）。VR组家长对操作过程的满意度高于对照组（P = 0.029），与对照组相比，VR组的操作难度程度更低（P = 0.026）。
术前VR教育显著降低了儿童的疼痛和焦虑，并降低了采血人员在静脉穿刺过程中的操作难度。
