This prospective randomized controlled study evaluates the impact of age-appropriate therapeutic play and structured parental briefing on perioperative anxiety during pediatric MRI under sedation. Children aged 2-11 were assigned to either a multi-modal intervention group or a standard care control group. The primary objective was to measure child anxiety using the Modified Yale Preoperative Anxiety Scale (m-YALE) after the intervention. Secondary objectives included assessing parental anxiety via VAS/APAIS and measuring overall parental satisfaction in the recovery room. The study aims to demonstrate that a brief psychological intervention can effectively reduce stress for both children and their parents, even during prolonged hospital waiting times.
