Effect of a Preparation Video on Preoperative Anxiety in Children Undergoing Dental Treatment Under GA

This randomised controlled trial, conducted at King Abdullah University Hospital (KAUH) over an eight-month period from February to October 2023, focused on children aged four to seven years undergoing comprehensive dental treatment under GA. Participants were randomly assigned to either the control group or the study group. Participants in the control group received the standard care provided upon arrival at the Day Case Unit (DCU) at KAUH, involving only a verbal explanation of the anaesthesia induction process. In contrast, on the night before the surgery, participants in the study group were presented with an animated video illustrating the story of a child's journey through the hospital facilities, including the anaesthesia induction, and the postoperative return home. Additionally, all parents watched the video alongside their children and provided positive comments on its content. The primary outcome assessed was the children's preoperative anxiety measured by modified Yale Preoperative Anxiety Scale (m-YPAS) and Visual Facial Anxiety Scale (VFAS), allowing for an evaluation of the intervention's impact.
