摘要
目的分析血液标本细菌感染后对微生物检验结果的影响。方法研究时间为2021年1月—2022年12月,纳入50例细菌感染的血液标本为分析组研究对象,另外纳入50例未受细菌感染的血液标本为对照组研究对象。所有研究对象均按照相同方法开展微生物检验,对最终的检验结果实施对比分析。结果分析组沙门菌检测阳性率、金色葡萄球菌检测阳性率、革兰阴性杆菌检测阳性率、布鲁杆菌检测阳性率、假丝酵母菌检测阳性率均高于对照组(P<0.05)。采集时消毒因素、送检因素、标本保存因素、患者自身因素均为导致细菌感染产生的原因,其占比分别为46.00%(23/50)、24.00%(12/50)、12.00%(6/50)、18.00%(9/50)。结论微生物检验结果会受到细菌感染血液标本的影响,且主要的影响因素为采集时消毒不规范,在日常工作开展中,为了进一步提高微生物检验结果准确率,需要强化对血液标本的防护工作,使细菌感染率有效降低,确保后续临床诊断及治疗工作更加顺利。
Objective To analyze effect of bacterial infection on microbial test results of blood samples.Methods The paper included 50 blood samples with bacterial infection as study subjects in analysis group from January 2021 to December 2022,and 50 blood samples without bacterial infection in control group.All research subjects were treated with microbiological testing with same method.Final test results was compared and analyzed.Results Positive rate of Salmonella detection in analysis group was 20.00%(10/50),Staphylococcus aureus detection was 24.00%(12/50),Gram negative bacilli detection was 36.00%(18/50),Brucella detection was 12.00%(6/50),and Candida detection was 8.00%(4/50),all higher than 4.00%(2/50),4.00%(2/50),6.00%(3/50),0.00%(0/50),and 0.00%(0/50)in control group(P<0.05).Disinfection factors,submission factors,specimen preservation factors,and patient factors were causes of bacterial infection during collection,accounting for 46.00%(23/50),24.00%(12/50),12.00%(6/50),and 18.00%(9/50)respectively.Conclusion Microbial test results can be affected by bacterial infection of blood samples,main influencing factors include improper disinfection during collection.In daily work,to further improve accuracy of microbial test results,it is necessary to strengthen protection of blood samples,reduce bacterial infection rates and ensure smooth clinical diagnosis and treatment in future effectively.
