Perioperative Effects of Operating Room Virtual Tour

The Effects of Operating Room Virtual Tour on Preoperative Anxiety, Emergence Delirium and Postoperative Behavioral Changes of Pediatric Patients: Prospective, Randomized, and Controlled Trial

Preoperative anxiety is associated with adverse consequences such as emergence delirium, and postoperative behavioral changes. According to previous studies, providing information of anesthetic procedures helps to lessen preoperative anxiety. However, verbal explanation alone provides the limited effect, and the tour program of the operating room prior to surgery may not be possible for a number of hospitals due to organizational and financial reasons. Therefore, the virtual reality (VR) tour of the operating room may be an innovative and novel method to give children information about the preoperative process and to alleviate the preoperative anxiety. In this study, we intend to evaluate the effects of the operating room virtual tour on preoperative anxiety as well as emergence delirium and postoperative behavioral changes, in pediatric patients.

At operation day, pediatric patients of the VR group and their parents are educated using virtual tour program explaining preoperative procedures and showing environment of the operating room. A 360-degree virtual reality (VR) video for the tour program was filmed in advance and is provided using a head mount device into which a smartphone is installed, at 30 minutes before the induction of anesthesia.

2 times; before the intervention (baseline) and, at waiting area, before the operating room entrance (preoperative)
