3种不同全自动血培养仪的临床应用及评价

目的评估Bact/Alert 3D、BD BACTEC FX以及Versa TREK 3种不同全自动血培养仪之间的应用价值及其相互差异。方法比较3种仪器的培养结果的报阳时间及延迟培养的报阳时间,评价3种仪器的临床应用价值。结果 3种血培养仪在培养时间的比较上,BD的最短报阳时间的瓶数所占比例是29.4%,梅里埃的最短报阳时间的瓶数所占比例为11.8%,Versa TREK的最短时间报阳瓶数所占比例为58.8%。在延迟培养的比较中,3种仪器的时间差距较小,延迟培养条件下建议在常温下保存(4℃条件下苛养菌可能死亡)。结论Versa TREK在细菌的培养时间上有一定的优势,但其存在操作较为繁琐,污染率相对较高的风险,Bact/Alert 3D、BD BACTEC FX在培养时间上差距不是很大,且操作方便。

Clinical application and evaluation of three different kinds of automatic blood culture instrument

Objective To assess the application value of 3 different kinds of Bact/Alert 3D ,BD BACTEC FX and Versa TREK automatic blood culture instruments and their mutual difference .Methods By using the contrast method ,the reported positive time for culture results and report positive time for delayed culture were compared a‐mong 3 kinds of instrument for evaluating their clinical value .Results In the comparison of culture time ,the bottle number proportion of shortest reported positive time for BD was 29 .4% ,which for Bact/Alert 3D was 11 .8% and which for Versa TREK was 58 .8% .In the comparison of delayed culture ,the time difference among 3 kinds of in‐strument was smaller ,under the delay culture condition ,the conservation under the room temperature was recommen‐ded(fastidous bacteria may die under the condition of 4 ℃) .Conclusion Versa TREK has certain advantages in the bacterial culture time ,but the risk of tedious operation and relatively high contamination rate exists ,the difference in the incubation time between Bact/Alert 3D and BD BACTEC FX is not very big ,which are easy to operate .
