The preoperative period in pediatric care often induces significant stress and anxiety in children, resulting in various maladaptive responses. These extreme levels of preoperative anxiety can have adverse effects on a child's immune system and hinder the healing process. This study's primary objective is the creation and evaluation of a perioperative comic book tailored to the specific needs of children undergoing surgery, with the aim of mitigating their preoperative anxiety. The study employs a research and development (R&D) method, specifically the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) approach. This comprehensive process involves crafting a media framework, compiling relevant materials, and developing engaging scenarios and storyboards. make it simple. The expert panel was composed of two material experts (4,81), two media experts (4,40), and two pediatric nurses practitioner (4,65). The rating test (1-5 scale) by the experts showed that comics were in the satisfactory category, which means that the perioperative comic book is valid and worthy of being tried out. The limited trial was carried out on 20 school-aged children who were about to undergo surgery. The testing results from users (n=20) show that comic book stories were considered very interesting (85%), easy to understand (85%), and helpful anxiety before surgery (100%). Perioperative comic books have been found to be helpful and suitable for children in reducing their anxiety before surgery. These comics also help kids get familiar with what happens in the hospital and during surgery, making the whole experience easier for them.
