摘要
目的评价双套血培养在提高血流感染检出率及鉴别污染的临床价值。方法统计2010—2011年上海交通大学附属第六人民医院双套血培养的双次阳性率和单次阳性率,评价双次阳性和单次阳性在鉴别血培养污染中的差异。结果我院2010—2011年共送检双套血培养3 151例,占全年送检病例数的71.2%。共检出483例阳性,阳性率15.33%。其中双次阳性192例,阳性率6.09%;单次阳性291例,阳性率9.23%。结论双套血培养能够提高血流感染检出率并能鉴别分离菌的定植或污染,建议临床在诊断血流感染时送检双套血培养。
Objective To evaluate the utility of duplicate blood cultures in identifying bloodstream infection and discriminating contamination. Methods The results of duplicate cultures during 2010 -2011 were analyzed in terms of single or double positive findings. The ability of discriminating contamination was compared between single and double positive cultures. Results Dupli- cate blood cultures were conducted for 3 151 blood samples in our hospital during the period from 2010 through 2011, about 71.2% of all the blood cultures in these two years. There were 483 (15.33%) positive cultures, including double-positive for 192 samples (192/3 151, 6.09%), single-positive for 29l (9. 230/oo, 291/3 151) samples. Conclusions Duplicate blood cultures can improve the detection of bloodstream infection and discrimination of contamination. Duplicate blood cultures should be ree ommended for identifying bloodstream infection.
