Kawasaki disease after the infusion of gammaglobulin 48 hours and then fever can be injected again gammaglobulin or the choice of glucocorticoid treatment. Kawasaki disease is a self-limiting disease, mostly seen in children, most of the prognosis is good, and its symptoms include high fever, mucosal congestion, rash, palpitation, pericarditis, myocarditis, cardiac arrhythmia, pneumonia, abdominal pain and so on. If the fever returns after a gammaglobulin infusion, the gammaglobulin may not be effective for the child, and a repeat gammaglobulin infusion is recommended, or glucocorticoids may be used. Glucocorticosteroids, in combination with aspirin and dipyridamole, are recommended for children for whom gammaglobulin has not been effective or for whom there is a risk of drug resistance. Note the use of glucocorticoids, such as prednisone acetate, at a dose of 1 to 2 mg/kg per day, with tapering and discontinuation of the drug over 2 to 4 weeks. If severe coronary artery disease occurs surgery is recommended, note that intravenous drugs should be administered by a professional.
