3-Dimensional Virtual Reality Versus 2-Dimensional Video for Distraction During the Induction of Anesthesia in Children to Reduce Anxiety: A Randomized Controlled Trial
Authors' conclusion
This randomized controlled trial demonstrated that preoperative anxiety was equally low and induction compliance high with both 3D VR and 2D video distraction in children with parental presence during anesthetic induction.
Study context
- Population
- Children (4–13 years) undergoing elective or emergency surgery under GAenrolled
- Participants
- Two hundred children
- Comparison
- 3D virtual reality (VR) vs 2D video
- 3D VRn = 98
- 2D videon = 90reference
- Primary endpoint
- Anxiety (modified Yale Preoperative Anxiety Scale Short Form, modified Yale Preoperative Anxiety Scale Short Form (mYPAS-SF)), preoperative holding area before randomization (T1) and during induction of GA (T2)
Primary result
As reported in the abstract
mYPAS-SF score during induction (T2) · during induction
| Group | Value | Preoperative holding area (T1) |
|---|---|---|
| 3D VR | median 29.2 (lower quartile, upper quartile 24.0–41.7) | 22.9 (22.9, 35.4) |
| 2D video | median 30.2 (lower quartile, upper quartile 22.9–41.1) | 27.1 (22.9, 35.4) |

2D video27.1 (22.9, 35.4)
- 3D VR vs 2D video: P = 0.672 — no significant difference
Secondary outcomes
| Outcome | P value |
|---|---|
| Perfect induction (Induction Compliance Checklist)3D VR less likely to be rated as perfect induction | P = 0.039 |
Emergence delirium (Cornell Assessment of Pediatric Delirium)
- No evidence of a difference between the groups
Usefulness and satisfaction
- Both devices rated highly for usefulness and patient satisfaction
- Children preferred VR; anesthesiologists and parents felt 2D more useful
