Abstract
A 5 year old boy with chronic renal insufficiency was admitted for the purpose of undergoing operation for CAPD catheter retention and introduction of CAPD. He had been explained by his parents about hospitalization and operation. After admission, fever and mental instability Considered due to his insufficient psycnological preparedness were noticed, so the operation was put off. As such, a picture book on the CAPD introduction in which characters he likes appear was made before operation. He was explained about the CAPD introduction by this book. Using this book, the child was able to concretely image and mentally prepare himself about the operation and CAPD introduction which had been an unknown experience and a source of fear to him. Apprehensions of his parents were also mitigated.
