Active Engagement Game Versus Passive Media During Pediatric Inhalational Induction

Preoperative anxiety is a highly prevalent complication in pediatric anesthesia, occurring in up to 50-60% of children undergoing surgery. High anxiety during the induction of anesthesia-particularly during the application of the face mask-is strongly correlated with poor induction compliance, increased risk of emergence delirium, higher postoperative analgesic requirements, and long-term negative behavioral changes.

To mitigate these risks, non-pharmacological behavioral interventions are widely integrated into routine pediatric perioperative care. While tablet-based audiovisual distraction (e.g., watching cartoons or playing games) has been shown to be a safe and effective alternative to pharmacological premedication, it is fundamentally limited by the physical realities of inhalational induction. Specifically, once the anesthesia mask is applied, children lose the physical ability to interact with standard digital games. Consequently, active distraction strategies frequently revert to passive observation at the exact moment when the child experiences the highest sensory distress.

Emerging evidence suggests that active cognitive engagement is superior to passive observation for sustained anxiolysis. However, there is a lack of specialized active distraction tools that safely integrate with the hands-on airway management workflow of the anesthesiologist. To address this gap, the investigators developed a novel, two-phase interactive iPad/phone game. During the awake pre-induction phase, the child interacts directly with the screen. As the anesthesia mask is applied, control of the game seamlessly transfers to a phone remote operated by the anesthesiologist. The anesthesiologist synchronizes the remote to the child's spontaneous respiratory rate, providing the child with active, breath-driven visual feedback on the iPad/phone screen without requiring their physical interaction.

The primary objective of this pragmatic randomized controlled trial is to determine whether this breath-synchronized active engagement game reduces the need for physical restraint during pediatric mask induction compared to standard passive media distraction.
