急危重症患者中心静脉置管相关性感染危险因素分析

对2010年12月~2013年9月在我院留置的急危重症患者的病历资料进行回顾性分析,分析中心静脉置管相关性感染(CVCRI)发生情况以及危险因素,并提出相应的干预措施。880例患者共有61例发生CVCRI,发生率为6.9%;分离出病原菌株65株,其中G+菌28株,G-22株,真菌15株;将这61例视为感染组,单因素分析显示,年龄、病情严重程度评分、免疫功能、导管留置时间及插管时机的差异具有统计学意义(p<0.05),进一步对上述因素进行多因素Logistic回归分析显示,病情严重程度评分、免疫功能和导管留置时间是CVCRI发生的独立危险因素。

Analysis of Risk Factors of Central Venous Catheter-Related Infection in Critical Patients

According to the date of medical information of critically ill patients who was admitted to hospital for observation,we retrospectively analyzed the occurring conditions and risk factors of central venous catheter infected by central venous catheter related infections(CVCRI),and proposed some related effective intervention measures.Among the 880cases,61 patients ware infected by CVCRI,so the incidence of infection would be 6.9%.Among 61 patients with CVCRI,65 pathogenic strains were isolated,including 28G+strains,22G-and 15 strains of fungi.Taking the 61 cases as an infection group,the single factor analysis showed that the difference of age,severity of illness,immune function,time of CVT,incubation timing had statistical significance.Through the further multivariate logistic regression analysis,we found that the severity of illness,immune function and incubation timing are the independent risk factors of CVCRI infection.
