The care of fulminant myocarditis should be divided into three aspects, which are routine care, high-flow oxygenation, rehydration care and so on. 1. Routine nursing: the ward should be kept quiet so that the patient can rest effectively, maintain absolute bed rest, and strictly limit activities. If patients have combined acute left heart failure, they should choose semi-sitting position. 2. High-flow oxygenation: High-flow oxygenation can effectively improve the hypoxic symptoms of the patients. If there are patients with combined pulmonary edema, 20%~30% alcohol can also be used for humidification of oxygen, which can effectively reduce pulmonary capillary exudation. 3. Rehydration nursing: a part of the patients may exist cardiogenic shock symptoms, so it is necessary to closely monitor hemodynamics, need to strictly follow the doctor’s instructions for infusion, to prevent the emergence of serious pulmonary edema. The care of fulminant myocarditis is mainly the above methods, it is recommended to strictly follow the doctor’s instructions for care.
