【摘要】：目的分析重症医学科导管相关性血流感染患者流行病学特点及危险因素。方法选取2015年4月-2016年4月医院重症监护室473例患者为研究对象,其中发生导管相关性血流相关感染(CRBSI)患者13例,随机选取非CRBSI患者26例为对照组,研究CRBSI患者流行病学特点及危险因素。结果共有动静脉插管398例,使用率为84.14%,13例发生CRBSI,感染率为2.75%;其中,两组患者的死亡数、平均年龄及糖尿病肾病对比差异有统计学意义(P0.05),而动静脉置管,泌尿道置管等病因对比,差异无统计学意义;两组空腹血糖升高6.1mmol/L水平,差异无统计学意义;CRBSI患者导管留置时间(14.24±2.12)d,急性生理与慢性健康评分(APACHE-Ⅱ)评分(22.30±5.40)分,CD4~+细胞(187.00±70.00)个/μl,体质量指数(BMI)(21.40±3.20)kg/m2,平均动脉压(MAP)(82.10±21.50)mmHg,ICU住院时间(10.30±2.50)d等指标都明显比非CRBSI患者差,两组对比差异有统计学意义(P均0.05);导管留置时间,APACHE评分,CD4~+细胞,MAP等进行单因素与多因素分析这些指标差异有统计学意义(P0.05)。结论对重症医学科导管相关血流感染患者,提高患者免疫力,缩短留置导管时间,降低MAP与APACHEⅡ评分及提升CD4~+细胞数量,可有效降低感染率。
[Abstract]:Objective to analyze the epidemiological characteristics and risk factors of catheter-related blood flow infection in severe medical department. Methods from April 2015 to April 2016, 473 patients in intensive care unit of hospital were selected as study subjects, including 13 patients with catheter-associated blood flow related infection, and 26 patients without CRBSI as control group. To study the epidemiological characteristics and risk factors of CRBSI patients. Results there were 398 cases of arteriovenous catheterization, and the rate of CRBSIwas 84.14%, and the infection rate was 2.75. There were significant differences in death, mean age and diabetic nephropathy between the two groups (P 0.05), while the causes of arteriovenous catheterization and urinary tract catheterization were compared. There was no significant difference between the two groups. Fasting blood glucose increased the level of 6.1mmol/L in the two groups. There was no significant difference in catheter indwelling time (14.24 卤2.12d), acute physiological and chronic health score (APACHE- 鈪，
