A systematic review shows VR interventions reduce preoperative anxiety in pediatric patients, suggesting valuable clinical use.

Evaluate the effectiveness of virtual reality interventions in reducing preoperative anxiety among pediatric patients.
Conducted a systematic review and meta-analysis of randomized clinical trials
Included studies comparing VR interventions to standard treatments or placebo
Analyzed anxiety levels before induction using standardized mean difference (SMD)
12 studies included in the analysis showed significant anxiety reduction (SMD = −0.69)
Immersive VR was more effective than non-immersive in reducing anxiety
Younger children (aged 3-6) had greater anxiety reduction compared to older children (aged 7+)
