Augmented reality in paediatric oncology patients undergoing surgery: a feasibility randomised controlled trial

Editor—In the USA, about 19 000 children are diagnosed with cancer annually.1 The acute postoperative pain treatment in children with cancer can be challenging.2,3 It is therefore necessary to identify novel drugs and non-pharmacological interventions to facilitate postoperative pain control.4,5 Among non-pharmacologic approaches to treat acute postoperative pain after paediatric surgery, augmented reality and virtual reality arise as attractive alternatives. Augmented reality superimposes virtual reality images onto real-world objects using existing mobile devices, and is widely used by children.
