Children who will undergo surgery for the first time and their families were randomly allocated into the control or VR group. The control group received conventional education regarding the perioperative process of surgery. The VR group watched a 1.5-minute VR video showing the operating theater and explaining the perioperative process. The main finding was preoperative anxiety evaluated using the Children's State Anxiety (CSA) before surgery. Secondary findings included children's postoperative pain ratings using Wong-Baker Faces Pain Rating Scale and parental satisfaction scores using PedsQL Health Care Satisfaction Scale
An immersive virtual reality (VR) tour of the operating theater before surgery could reduce preoperative anxiety. The aims of this study were to analyze whether a preoperative virtual reality tour shows a reduction in anxiety in children and an increase in parental satisfaction.
