Catheter Colonization in Hemodialysis Patients : Comparison with Cuffed & Tunnelled Dialysis Catheter (Permcath(R)) and Noncuffed Dialysis Catheter (Gamcath(R)) / 대한신장학회지

ABSTRACT

PURPOSE: The aim of this study is to investigate incidence and related affecting factors on bacterial colonization and bacteremia of cuffed & tunnelled dialysis catheter and noncuffed dialysis catheter. METHODS: This study was performed retrospectively through review of medical records from May 2005 to May 2006. 102 central venous catheters for hemodialysis were analyzed cuffed & tunnelled dialysis catheter (n=32, group P); noncuffed dialysis catheter (n=70, group G). RESULTS: There was no difference between group P (15.6%) and group G (15.7%) in cumulative incidence of catheter colonization. However, in terms of risk for colonization with time, incidence density of group P was lower than group G (group P, 1.17/1,000 catheter days; group G, 12.97/1,000 catheter days). In the subgroup analysis of group G, incidence density of internal jugular vein group was lower than femoral vein group (internal jugular vein catheter, 7.54/1,000 catheter days; femoral vein catheter, 32.43/1,000 catheter days). CONCLUSION: The risk of catheter colonization turned out higher in noncuffed dialysis catheter than in cuffed & tunnelled dialysis catheter. Therefore, more delicate antiseptic cares for dialysis catheter were needed in case of emergency. Additionally, permanent vascular access should be placed earlier to avoid insertion of temporary dialysis catheter in end-stage renal disease.
