Description

After receiving IRB approval from our institution and consent from parents or guardians, ASA I or II status children ages 4 - 10 presenting for surgery requiring general anesthesia were recruited for this study. They were assigned to either tablet- or VR-based groups. At our institution, tablet-based distraction is widely used and represents standard practice. Children in this control group were given tablets in the preoperative holding area before transport to the operating room. Content consisted of entertainment apps providing access to music videos, movies and games targeting various age groups.

The study group was given a Virtual Reality Smartphone headset in the preoperative holding area prior to transport to the operating room. This headset was chosen because of its low cost and wide compatibility for a variety of smartphones. The content consisted of several VR environments that the child/parent could choose from.

In both groups, the distraction with tablet or VR was continued throughout separation from caregivers, transport to the operating room, placement of monitors and mask induction of general anesthesia. Anxiety at time of separation was measured by the modified Yale Preoperative Anxiety Scale (mYPAS). Caregiver anxiety was measured using the State-Trait Anxiety Inventory for Adults (STAI). Mask acceptance at induction of anesthesia was determined by using the Mask Acceptance Scale.
