直接药敏试验法和常规药敏试验法在血液细菌检验中的应用研究

Direct Application of Conventional Susceptibility Testing and Susceptibility Testing of Bacteria Inspection in the Blood Test

目的探讨两种药敏试验方法在血液细菌检测中的临床应用价值。方法选择在我院检查的280份患者阳性血液标本进行常规药敏试验法和直接药敏试验法,并对试验结果进行比较分析。结果直接药敏试验法对革兰氏阳性菌和革兰氏阴性菌检测的符合率与常规法比较差异无统计学意义(P>0.05)。两种药敏试验结果的检验敏感性比较差异无统计学意义(P>0.05)。结论直接药敏试验法和常规药敏试验法在临床血液细菌检验中的检出符合率均较高,但直接药敏试验法操作简单、时间相对较短,更有助于临床细菌感染的血液检测。

Objective To explore the clinical value of detecting bacteria in the blood test. Methods Selecting 280 patients in the hospital as positive blood samples for routine susceptibility testing and direct susceptibility testing, and the test results were analyzed. Results There was no statistically significant difference between the coincidence rates of direct testing method and routine method of gram- positive bacterium and gram- negative bacterium（ P 0. 05）. Two susceptibility testing susceptibility test results showed no significant difference（ P 0. 05）. Conclusion Direct susceptibility testing and routine susceptibility testing of bacteria detected in clinical blood tests have the higher rates,but simple and direct susceptibility testing operation needs a relatively short time and does favor to clinical bacterial infection of the blood test.
