导管留置感染的概念尚未确立,目前仍处于从细菌性导管败血症至临床性导管热,来研究有各种各样的病理改变的混乱状态。所以研究阐明其机制的理论,指导诊断和采取措施,是目前的重要课题。从1990年8月至1991年7月一年间,作者在医院透行的高能输液共268例,330次。其中90.3％是恶性疾病,与手术有关的病例占79.1％。进行日数平均30.3天(3～213天),因发热而中断或中止的例数为112次,占33.9％,治疗结束例只有47.6％。死亡病例为16.1％,自己或自然拔出例为2.4％。对拔出导管的尖部透行培养,结果303次中有27例占8.9％为细菌培养阳性,检出了28株(CSFI 2.7),进而从导管及外周静脉分别采血,包括用后述的分离器培养的 The concept of catheterized infection has not been established and is currently in the pipeline from bacterial catheter sepsis to clinical catheterization to investigate the chaos of various pathological changes. Therefore, it is an important issue at present to study the theory of clarifying its mechanism, guiding diagnosis and taking measures. During the one-year period from August 1990 to July 1991, a total of 268 high-energy transfusions conducted by the author in the hospital were delivered 330 times. Of these, 90.3% were malignant and 79.1% were related to surgery. The average number of days performed was 30.3 days (3 to 213 days). The number of patients who discontinued or stopped fever due to fever was 112, accounting for 33.9%. Only 47.6% of patients completed the treatment. 16.1% of deaths, or 2.4% of their own natural withdrawal. Percutaneous culture of the tip of the catheter was performed. As a result, 27 of the 303 patients (8.9%) were positive for bacterial culture and 28 (CSFI 2.7) were detected. Blood was collected from the catheter and the peripheral vein, Separator cultured
