Abstract:

Ｏｂｊｅｃｔｉｖｅ：To analyze the  character of vascular access and its complications in patients receiving continuous renal replacement therapy (CRRT).
Ｍｅｔｈｏｄｏｌｏｇｙ：The patients who treated with CRRT from April 2014 to Septemper 2014 in our hospital were included in this study. Demographic data was collected and laboratory test results were conducted. The data of vascular access were obtained from our database.
Ｒｅｓｕｌｔｓ：A total of 292 patients was enrolled in the study. Patients who needed CRRT  were mainly caused by AKI, MODS and SIRS. Initial vascular access was noncuffed temporary catheters in 280 patients and it was preferentially obtained in the right internal jugular vein (543%). There were 32 (114%) patients needed recatheterization. Catheter malfunction accounted for 714% of all patients, and the median time of catheter malfunction was found at the 5th day. By multivariate analysis, it was found that the main risk factors of catheter malfunction were cumulative treatment time of CRRT and the level of hemoglobin. The average time of catheterrelated infections was 107 days after insertion and the  catheterrelated infections were 719 per 1000 catheter days. The main risk factors of catheterrelated infections were cumulative time of catheterization and the level of serum albumin.
Ｃｏｎｃｌｕｓｉｏｎ：
In the present crosssectional study,  the initial vascular access was noncuffed temporary catheter in CRRT patients, and the first inserted site was the right internal jugular vein. Some patients needed recatheterization during CRRT. The main risk factors of catheter malfunction were cumulative time of CRRT and the level of hemoglobin. In addition, the main risk factors of catheterrelated infections were cumulative time of catheterization and the level of serum albumin.
