Children frequently experience anxiety, pain, and negative behavioral changes during common medical procedures such as venous blood sampling, vaccination, injection, and peripheral intravenous catheter insertion. Providing developmentally appropriate procedural preparation before these procedures may improve children's experiences and reduce procedure-related distress. This multicenter randomized controlled trial evaluates the effectiveness of an artificial intelligence (AI)-supported visual guide developed to prepare preschool children aged 3-6 years for common medical procedures. The intervention consists of standardized 1-3-minute procedure-specific educational videos created using Google Gemini 2.5 Pro (Google DeepMind) and finalized using CapCut. The videos incorporate researcher-developed educational scripts, AI-generated illustrations, and AI-generated voice narration to provide child-friendly, visually engaging, and developmentally appropriate procedural preparation. A total of 110 children are randomly assigned to either an intervention group receiving the AI-supported visual guide before the procedure or a control group receiving routine care. The primary outcome is procedural anxiety assessed using the Modified Yale Preoperative Anxiety Scale (mYPAS). Secondary outcomes include procedural pain measured using the Face, Legs, Activity, Cry, and Consolability (FLACC) Pain Scale and post-procedural behavioral changes measured using the Post Hospitalization Behavior Questionnaire for Ambulatory Surgery (PHBQ-AS).
