本文对感染性心内膜炎的血培养和较新诊断技术的敏感性和特异性进行对比。血培养:对疑有心内膜炎者,至少在数小时至几夭内取三次血培养。常规进行需氧及厌氧血培养。培养阴性时需要再培养和孵育21天,因为感染性心内膜炎偶可由生长缓慢或营养摄取慢的病源体所引起。感染性心内膜炎培养阴性者约为15男。应用抗菌素是培养阴性的常见原因。在应用
This article compares the sensitivity and specificity of blood cultures for infective endocarditis with more recent diagnostic techniques. Blood culture: In patients with suspected endocarditis, at least in a few hours to take blood cultures three times within a few days. Conventional aerobic and anaerobic blood culture. Reproduction and incubation for 21 days are required for culture negative, as infective endocarditis can occasionally be caused by a pathogen that is slow to grow or slow to nutrient uptake. Infective endocarditis culture negative about 15 men. Application of antibiotics is a common cause of culture negative. In use
