The purpose of this study was to evaluate the prognosis of patients with central venous catheter (CVC) sepsis, with particular reference to two therapeutic procedures, 1) CVC exchange over a guide wire and 2) removal of the catheter An evaluation was made of the clinical records of 22 cancer patients receiving total parenteral nutrition because of severe malnutrition and of 27 CVC-related septic episodes defined as growth of the same microorganism on the CVC and in peripheral blood. Bacteriological findings included Candidae n = 17, S albus n = 4, E Cloacae n = 4, Enterococcus n = 1 and P aeruginosa n = 1. In 22 cases the CVC was exchanged and in five cases it was removed on the clinical suspicion of CVC-related sepsis. Nineteen of the 22 patients had their blood culture rendered negative with CVC exchange and in three of the other five patients it was resolved bacteriologically after removal of the CVC. There was no clear effect of the CVC sepsis on the final outcome of the patients' illness. In fact, seven patients eventually died because of reasons apparently unrelated to the CVC sepsis-which had bacteriologically and clinically resolved-and seven patients recovered and were discharged in good condition despite the initial failure of CVC manipulation. The conclusion reached was that death should not occur as a result of CVC sepsis, provided this is properly identified and adequately treated. Since CVC change allows earlier recognition of the complication and effective treatment, it may be considered the therapy of choice in the management of suspected CVC sepsis.
本研究的目的是评估中心静脉导管(CVC)败血症患者的预后,特别参考两种治疗方法:1)经导丝更换CVC;2)拔除导管。对22例因严重营养不良接受全胃肠外营养的癌症患者的临床记录以及27例CVC相关败血症发作进行了评估,CVC相关败血症发作定义为CVC和外周血中生长相同微生物。细菌学检查结果包括念珠菌属17例、白色葡萄球菌4例、阴沟肠杆菌4例、肠球菌1例和铜绿假单胞菌1例。22例患者更换了CVC,5例因临床怀疑CVC相关败血症而拔除了导管。22例患者中有19例通过更换CVC使血培养转阴,另外5例中的3例在拔除CVC后细菌学检查结果转阴。CVC败血症对患者疾病的最终结局没有明显影响。事实上,7例患者最终因明显与CVC败血症无关的原因死亡(CVC败血症在细菌学和临床上均已缓解),7例患者尽管最初CVC操作失败,但仍康复并顺利出院。得出的结论是,只要正确识别并充分治疗CVC败血症,就不应导致死亡。由于更换CVC能更早识别并发症并进行有效治疗,因此在疑似CVC败血症的管理中可将其视为首选治疗方法。
