1399例儿科血培养结果分析

Analysis of blood culture results of 1399 cases in pediatrics

目的:了解儿科血液感染微生物种类及分布,指导临床医生合理用药。方法:分析2014年1月—2014年6月儿科血培养结果,进行细菌学鉴定。结果:所选标本阳性121例,总阳性率8.65%。其中主要分离出表皮葡萄球菌32株(26.45%)、大肠埃希菌5株(4.13%)、人葡萄球菌56株(46.28%)、溶血性葡萄球菌8株(6.61%)。结论:检测结果显示,人葡萄球菌和表皮葡萄球菌占72.73%,由于抗生素的广泛应用,导致条件致病菌的感染,部分原因是样本采集过程操作不当污染所致。根据患儿血培养情况,需要加强对抗生素应用管理,减少条件致病菌的感染,加强标本采集的宣教,避免操作污染所导致的阳性率的增加。

Objective： According to understand pediatric microbial species and distribution of blood infection,to guide clinicians rational drug use. Methods： To anzlyze the pediatrics blood culture results from January 2014 to June 2014,to identify the bacteriology. Results： Ppositive specimens of 121 cases,the total positive rate was 8. 64%; mainly in the specimens of 121 cases of blood culture positive for epidermis staphylococcus aureus was isolated 32 strains accounted for about 26. 45%,5strains of e. coli accounted for about 4. 1%,56 strains staphylococcus aureus accounted for about 46. 28%,8 strains of hemolytic staphylococci accounted for about 6. 61%. Conclusion： Testing results showed that staphylococcus aureus and epidermis staphylococcus aureus accounted for about 72. 73%,may be due to the widespread use of antibiotics,the condition caused by the infection,some may be sampling process improper operation caused by pollution. According to the situation of children ＇s blood culture,the need to strengthen the management of antibiotics application,reduce the specimen of conditional pathogenic bacteria infection and mission,avoid the pollution caused by the operation rate of increase.
