CLINICAL UTILITY OF IV CATHETER TIP CULTURES FOR SHORT TERM LINES

静脉导管尖端的培养已经是 持续了十年。根据Maki等人的研究结果， 一种基于在血琼脂平板上滚动尖端并计数 由此产生的菌落数量一直是我们使用的“标准”做法， 实验室和其他实验室一样。的有效性和价值 这些文化引起了越来越多的争论，但很少有文献记载 已经公布了数据来澄清这一问题。作为一个更大的系列的一部分 维持CCM部门方案，我们的研究将使用这些患者 观察菌落计数及其在确定品系中的预测价值， 短期中心静脉导管引起的脓毒症。生物体将被保存，因此， 导管分离物和血液分离物可以通过分子生物学方法进行比较。 流行病学技术，以确定它们是否相同或不同 菌株

Culture of intravenous catheter tips has been a routine practice for the last ten years. Based on the findings of Maki et al, a quantitative technique based on rolling the tip on a blood agar plate and counting the resulting number of colonies has been a "standard" practice used by our laboratory as well as most other laboratories. The validity and value of these cultures has come into increasing debate, but little well documented data has been published to clarify this issue. As part of a larger line maintenance CCM department protocol, our study will utilize these patients to look at colony counts and their predictive value in determining line sepsis from short term central lines. Organisms will be saved, so that catheter isolates and blood isolates can be compared by molecular epidemiological techniques to determine if they are the same or different strains.
