The book provides a comforting yet accurate overview of the anesthetic process for surgery, aimed at children who are injured and frightened about what to expect. It explains the journey from preoperative holding to the operating room and then to the post-anesthesia care unit. The narrative highlights the steps involved in anesthesia in a medically accurate yet fun and playful way, making the child feel as if they are embarking on a rocket ship ride under anesthesia. This process is portrayed as safe and guided by the anesthetist, who is depicted as a knowledgeable and compassionate guide. The child is introduced to the medical equipment they will encounter, such as the face mask, reservoir bag, and vital sign monitors, making them appear approachable and less intimidating. Additionally, the anesthetist is portrayed as an "anesthesia angel" and a real-life superhero, alongside various other healthcare providers who are dedicated to helping and caring for the child. All medical personnel are in scrubs. Ultimately, the child undergoes an inhalational general anesthetic and emerges as their own "astronaut of anesthesia" superhero filled with pride and a beaming smile.
