Preoperative paediatric anxiety is a common phenomenon usually associated with surgery and has a negative effect on postoperative recovery like higher postoperative pain, emergence delirium, uncooperative behavior, and higher doses of sedation or preoperative analgesia. In this generation the use of smartphones is more so this study aims to reduce preoperative anxiety in children undergoing surgeries under anaesthesia using smartphone as a distraction technique. Material and method: This blinded randomized clinical trial included 40 children aged 3 to 12 years undergoing a planned surgical intervention at a GMERS general hospital divided into Group A (n = 20) and Group B(n = 20) groups. The video was shown on a smartphone to children in the experimental Group A preceding a planned surgical procedure. The control Group B was posted for surgery without intervention. Results: There was statistically significant reduction in mYPAS score in Group A as compared to Group B. Conclusion: Smartphone can be used to reduce preoperative paediatric anxiety as a distraction technique.
