摘要
目的研究直接药敏试验与常规药敏试验在临床血液细菌鉴定与检验中的临床应用价值。方法选择阳性血液标本690份,对每份样本同时采用直接药敏试验和常规药敏试验检测,并分析两种检测方法各细菌鉴定结果及药敏结果的符合率。结果两种检测方法间G+球菌敏感度无明显差异(Z=-0.217,P>0.05)。两种方法间G-杆菌敏感、中度敏感、耐药的符合率亦无明显差异(Z=-1.109,P>0.05)。结论直接药敏试验与常规药敏试验符合率较高,直接药敏试验且具有检测时间短,操作简单等优势,可广泛应用于细菌感染的临床血液检验。
Objective To investigate the direct antimicrobial susceptibility test（DAST） and Conventional antimicrobial susceptibility test（CAST） in bacterial identification and test.Methods 690 cases positive bloody samples,which were tested both in DAST and CAST.The coincidence rate of the results of identification and antimicrobial susceptibility test were analyzed.Results There were no significant differences in antimicrobial susceptibility test of gram-positive bacteria （Z=-0.217,P〉0.05） and gram-negative bacteria（Z=-1.109,P〉0.05） between two methods. Conclusion The identifying efficacy and antimicrobial susceptibility testing capacity of DAST have high coincidence rate compared with CAST.Thus,it deserves clinical promotion in blood test of bacterial infection patients.
