[Diagnosis and treatment of causes of fever after open heart surgery].

The causes of fever in 171 cases 10 days after 1527 cases of open heart surgery were analysed. The common noninfectious causes of fever were postpericardiotomy syndrome (35.8%) and drug fever (26.9%). The infectious causes of fever were respiratory system infection (18.1%), chest wall and incision infection (9.9%), infectious endocarditis (7.0%) and transfusion malaria (2.4%). In this paper, the diagnosis, prevention and treatment of common causes of fever after open heart surgery were discussed. The authors believed that etiologic diagnosis of fever and reasonable antibiotic use were key measures.
