Augmented Reality Improves Pediatric Mask Induction: A Prospective, Matched Case-Control Study.

Introduction

Pediatric perioperative anxiety is a significant problem during mask induction for general anesthesia. Immersive technologies, such as extended reality headsets, are a promising strategy for alleviating anxiety. Our primary aim was to investigate mask acceptance during inhalational induction utilizing augmented reality (AR).

Methods

This was a prospective, matched case-control study at a quaternary academic hospital. Fifty pediatric patients using AR for mask induction were matched to 150 standard-of-care (SOC) controls. The primary outcome was measured with the Mask Acceptance Scale (MAS). Secondary outcomes of cooperation and emergent delirium (ED) were assessed.

Results

MAS scores ≥2 occurred at 4% (95% CI [0, 9.4%]) with AR versus 19.3%, (95% CI [13%, 25.7%]) with SOC (RR 0.21, 95% CI [0.05, 0.84], P = .027). Ninety-eight percent of AR patients were cooperative versus 91.3% with SOC (P = .457). Zero percent had ED with AR versus 0.7% with SOC (P = 1.000).

Conclusions

AR during mask induction improved mask acceptance compared to SOC. No relationship was observed between AR and cooperation or ED. Future research will investigate the integration of AR into clinical practice as a nonpharmacologic intervention.
