Necrotizing fasciitis is invariably followed by sudden deterioration with rapid progression. Patients with necrotizing fasciitis, apart from surgical debridement or even amputation, may easily develop respiratory failure and eventually die. This paper explores the experience of emergency nursing care for a 62-year-old male patient with cirrhosis. The patient had necrotizing fasciitis due to skin swelling and rashes; his left arm required amputation below the elbow. From July 27 to 30, 2014, the researcher used Gordon's 11 functional health patterns to perform direct nursing, observations, interviews, data collection, and track interviews. Analysis and rearrangement of the subjective and objective information that was collected confirmed that the patient had health problems of pain, body dysmorphic disorder, and failure of respiratory tract clearance function. Listening to the patient and accompanying him with patience, the researcher encouraged him to express and vent his emotions. Having understood the patient's feelings, the researcher encouraged his family members to join the nursing and caring activities, and the patient gradually faced and accepted the fact that his arm needed to be amputated. Through this experience, the researcher would like to share with other nursing staff that when nursing patients with necrotizing fasciitis, we need to not only maintain the stability of the patient's vital signs but also pay attention to other problems that the patient might be experiencing such as psychological concerns, home care after amputation, discharge from hospital, and adaptation to society. We should assist patients in rebuilding their confidence in life, and enable them to redevelop a positive attitude toward human life.
