Abstract: Objective To explore the factors relating to catheter infection in hemodialysis patients with temporary central vein catheterization. Methods Eighty- two hemodialysis patients with temporary central vein catheter and treated in the period of February to December 2012 in our hospital were retrospectively surveyed.
Patients were divided into several groups according to position of the catheter, diabetes, nutrition indicators (hemoglobin and albumin), age and eGFR. Their catheter infection rate was investigated. Results The catheter infection rate was higher in femoral vein (28.8%) than in internal jugular vein ( 6.7%; χ2=5.695, P＜0.05),  and was higher in patients with diabetes (33.3%) than those without diabetes (12.2%; χ2 =5.336, P＜ 0.05). The catheter infection rate was also influenced by the nutrition indicators of hemoglobin and albumin (P＜0.05), but not by age and eGFR of the patients (P＞0.05). Conclusions Catheter infection in hemodialysis patients with temporary central vein catheterization was related to position of the catheter, diabetes and nutrition indicators (hemoglobin and albumin). These factors should be taken into consideration to prevent catheter infection in hemodialysis patients with temporary central vein catheterization.
