This study discusses the nursing experience of a young man who underwent Nuss procedure for the diagnosis of a pectus excavatum. The patient was hospitalized from 2020/6/1 to 2020/6/9. Guided by the Roy's adaptation model, the psychological aspects of the Taiwanese version of the World Health Organization Quality of Life Questionnaire-brief (WHOQOL-brief) were used to assess the psychological adaptation of the patient. The author collected data through observation, interview and case consultation. The patient's problems were found to include acute pain, physical dysfunction and body image disturbance. The author established a good nursing relationship with the patient, provided pain relief methods, and assisted in adopting progressive rehabilitation activities. Empathy, companionship and support were given to enhance the patient's self-confidence, acceptance of their own imperfections, and face the disease with a positive attitude. It is hoped sharing this nursing experience can provide future clinical reference for nursing staff, and help achieve all-round physical and mental care in similar patients.
