目的本文主要对ICU导管相关性血流感染(CRBSI)的感染及危险因素进行全面的分析。方法 1003例住院时间>24 h、年龄>2个月的患者,运用前瞻性的检测方式对置管患者的病情进行分析,从划分危险因素的等级来实施监控CRBSI患者。结果 1003例患者中750例采用了血管内置管的实验,综合的覆盖率为75%;广谱抗菌药物主要有:三代头抱菌素类、哌拉西林/他唑巴坦、帕尼培南、万古霉素、喹诺酮类。27.9%患者之前用过抗真菌药物,最常见的抗真菌药物是大扶康。置管时间:在置管5 d前发生感染的占19.3%,置管7 d后发生感染的占80.7%;感染前人均住院19 d。置管的时间和频率越长越多,CRBSI覆盖率随之逐渐增大(P<0.05),分别最高达16.3%,27.8%;置管的时间和频率是CRBSI产生危机因素。结论 ICU的CRBSI检测危险因素的标准依照两方面:留置时间与置管频率。如果定时对双手进行清洁、在无菌环境中置管以及保养、使用后立即拔除导管,就能防止CRBSI的出现和发展。
Objective This article is a comprehensive analysis of ICU catheter-associated bloodstream infections (CRBSI) infection and risk factors. Methods A total of 1003 patients with> 24-h hospital stay and> 2 months of age were enrolled in this study. Prospective testing methods were used to analyze the condition of patients undergoing catheterization and CRBSI patients were monitored from the classification of risk factors. Results Among 1003 patients, 750 cases were treated with endovascular catheter and the comprehensive coverage rate was 75%. The broad-spectrum antibacterial drugs mainly include: third generation cephalosporins, piperacillin / tazobactam, panipenem , Vancomycin, quinolones. 27.9% of patients had previously used anti-fungal drugs, the most common anti-fungal drug is Tai Fu Kang. The duration of catheterization was 19.3% before catheterization 5 days and 80.7% after 7 days of catheterization. The average hospitalization time before infection was 19 days. The longer the time and frequency of catheterization, CRBSI coverage gradually increased (P <0.05), up to 16.3% and 27.8% respectively. The time and frequency of catheterization were the risk factors of CRBSI. Conclusion ICU CRBSI criteria for detecting risk factors according to two aspects: indwelling time and catheter frequency. If the regular cleaning of both hands, in a sterile environment, care and maintenance, the use of catheter immediately after removal, you can prevent the emergence of CRBSI and development.
