Developing a Health Game to Prepare Preschool Children for Anesthesia: Formative Study Using a Child-Centered Approach.

Background: Every year, millions of children undergo medical procedures that require anesthesia. Fear and anxiety are common among young children undergoing such procedures and can interfere with the child's recovery and well-being. Relaxation, distraction, and education are methods that can be used to prepare children and help them cope with fear and anxiety, and serious games may be a suitable medium for these purposes.
