Abstract

A prospective study was conducted over eight months to evaluate the usefulness of two culture techniques using different catheter parts for detection of bacterial colonization or catheter-related bacteremia in patients with jugular or subclavian hemodialysis catheters. A combination of semiquantitative culture of the external surface and quantitative culture of the intraluminal surface of the intradermal catheter segment provided the best means of detecting catheter colonization. For detection of catheter-related bacteremia, this combination had 100% sensitivity and a positive predictive value similar to the actual rate of catheter-related bacteremia.

摘要

进行了一项为期八个月的前瞻性研究，以评估使用不同导管部位的两种培养技术在检测颈内或锁骨下血液透析导管患者细菌定植或导管相关菌血症方面的效用。皮内导管段外表面的半定量培养与管腔内表面的定量培养相结合，提供了检测导管定植的最佳方法。对于检测导管相关菌血症，这种组合具有100%的敏感性，阳性预测值与实际导管相关菌血症发生率相似。
