摘　　要：目的调查血培养污染的发生率以及寻找相应的护理对策。方法对医院2008-2010年送检的血培养标本结果进行回顾性调查,调查血培养污染的发生率。结果 27 128份送检的血培养标本中,培养出的细菌2253份,阳性率为8.3%,在2253份血培养阳性的样本中,判断为污染菌有651份,总污染率为2.4%,血培养阳性样本中的污染率为28.9%,735株污染菌主要为凝固酶阴性葡萄球菌581株,占79.0%。结论血培养污染发生率较高,污染菌主要为皮肤定植的凝固酶阴性葡萄球菌,应改进相应的护理措施,降低污染的发生率。OBJECTIVE To investigate the prevalence of contamination in blood culture samples and look for the corresponding nursing countermeasures.METHODS The results of blood culture samples submitted from 2008 to 2010 were investigated retrospectively,the incidence of the contamination of blood culture was investigated.RESULTS The bacteria were cultured from 2253 of 27 128（8.3%） submitted blood culture samples,651 samples were contaminated by colonized bacterial isolates.The prevalence of contamination in all blood culture samples was 2.4%,and the contamination rate of the blood culture-positive samples was 28.9%;Of 735 strains of contaminated bacteria,there were 581 strains of coaguase-negative Staphylococci isolates,accounting for 79.0%.CONCLUSION The incidence of contamination of blood culture is high.The bacteria contaminating blood culture samples are skin colonized coaguase-negative Staphylococci isolates,it is necessary to improve the corresponding nursing measures to reduce the incidence of contamination.
