维持性血液透析导管相关感染危险因素分析

Risk Factor Analysis of Catheter-Related Infection in Maintenance Hemodialysis Patients

摘要: 目的：探讨引起血液透析患者导管相关感染的主要危险因素，为制定相关的预防和治疗措施提供科学依据。方法：选取2008年1月~2O14年12月我院留置中心静脉导管进行维持性血液透析的970例患者的临床资料进行回顾性分析，采用单因素和多因素Logistic回归分析对有导管相关性感染组和无导管相关性感染组的各项临床指标进行分析，找出影响导管相关感染的危险因素。结果：970例留置中心静脉导管病人中引起导管相关性感染者82例(8.45%)，置管部位、导管留置天数、原发病因、血浆白蛋白水平是导管相关性感染的独立危险因素。结论：维持性血液透析患者留置中心静脉导管容易发生相关感染，且与多个因素有关，应针对这些因素进行积极纠正，才能有效预防感染发生。

Abstract: Objective: To analyze the main risk factors of catheter-related infection in hemodialysis patients, so as to provide scientific proof to make the preventive and treatment measures. Methods: The clinical data of the 970 cases of maintenance hemodialysis patients from January 2008 to December 2014 were studied retrospectively; Stepwise logistic regression analysis was performed to identify risk factors associated with catheter-related infection. Results: Catheter related infection in 82 (8.45%) cases from 970 cases of central venous catheter patients. The site of catheter, catheter-retaining number of days, the primary cause, plasma albumin level, were independent risk factors of catheter-related infection. Conclusion: Patients in maintenance hemodialysis with indwelling central venous catheter related infection was easy to occur, and related to many factors, these factors should be focused on positive correction, to prevent infection.
